The Short Answer: How Long to Microwave a Small Potato

For most people, the quick answer is this: microwave a small potato for about 5 to 7 minutes on high power, flipping it halfway through. This assumes a standard 1000-watt microwave and a potato weighing roughly 4 to 6 ounces, which is about the size of your fist or slightly smaller. If your microwave has a lower wattage, you may need to add 1 to 2 minutes. If your potato is very small, start with 4 minutes and add more time as needed.

Because potatoes vary in size, shape, moisture content, and starch level, no single time works perfectly for every potato. The best approach is to start with a conservative time, test for doneness, and add more time in short increments if needed. This prevents overcooking and gives you control over the final texture.

In general, plan for these rough ranges:

• Very small potato (3 to 4 ounces): 4 to 5 minutes
• Small potato (5 to 6 ounces): 5 to 7 minutes
• Medium-small potato (7 to 8 ounces): 7 to 9 minutes

These times assume high power and a single potato. Cooking two or more potatoes at once increases the total time, usually by about 50 percent for the second potato.

What Counts as a Small Potato

Before you can answer “How Long to Microwave a Small Potato?” accurately, you need to know what size you are actually working with. Grocery stores sell potatoes in many sizes, and the label on the bag does not always tell you much. A small potato is generally one that weighs between 4 and 6 ounces, or roughly 115 to 170 grams. It is about the size of a tennis ball or slightly smaller, and it fits comfortably in the palm of your hand.

Common varieties sold as small potatoes include baby potatoes, new potatoes, fingerlings, and small Yukon Golds. These are often sold in mesh bags or plastic containers. They are popular because they cook quickly, have thin skins, and are easy to portion for one person.

If you are unsure about size, use a kitchen scale for accuracy. Weighing the potato takes only a few seconds and removes the guesswork. If you do not have a scale, compare the potato to a standard tennis ball or a computer mouse. Anything significantly larger should be treated as a medium potato, which needs more time.

Shape matters too. A long, thin potato cooks faster than a round, thick one because heat penetrates more evenly along a slender shape. If your small potato is oddly shaped, check it a minute earlier than usual.

Factors That Affect Microwave Time

Several factors influence how long to microwave a small potato. Understanding them helps you adjust the timing instead of relying on a single number.

Microwave Wattage

Microwave ovens range from about 600 watts in compact models to 1200 watts or more in full-size units. Higher wattage means faster cooking. Most standard household microwaves are around 1000 watts. If your microwave is 700 watts, add roughly 30 to 50 percent more time. If it is 1200 watts, reduce the time slightly.

Potato Moisture and Starch

Waxy potatoes, such as red potatoes and fingerlings, contain more moisture and less starch. They tend to cook slightly faster and stay firmer. Starchy potatoes, such as Russets, take a bit longer and become fluffier inside. New potatoes, which are harvested young, have thinner skins and higher moisture, so they cook quickly.

Starting Temperature

A potato taken straight from the refrigerator takes longer than one at room temperature. Cold potatoes can add 1 to 2 minutes to the cooking time. For best results, let the potato sit at room temperature for 10 to 15 minutes before cooking, or simply add a little extra time.

Number of Potatoes

Cooking two potatoes at once does not simply double the time, but it does increase it. For two small potatoes, add about 2 to 3 minutes to the total. For three, add another 1 to 2 minutes. Arrange them in a ring so they cook evenly.

Hot Spots and Turntable

Most modern microwaves have a turntable that rotates food for even heating. If your microwave lacks a turntable, you will need to rotate the potato manually halfway through. Microwaves also have hot spots, so flipping and rotating the potato is essential for even cooking.

Step-by-Step: How to Microwave a Small Potato

Follow these steps for a perfectly cooked small potato every time. This method works for most varieties and most microwaves. (See Also:How Long To Steam Broccoli In Microwave)

1. Wash the potato. Scrub it under running water to remove dirt. You can use a vegetable brush. Pat it dry with a paper towel.
2. Poke holes. Use a fork to pierce the potato 4 to 6 times all over. This allows steam to escape and prevents the potato from bursting.
3. Optional: rub with oil and salt. For better flavor and slightly crispier skin, rub the potato lightly with olive oil or vegetable oil and sprinkle with salt. This step is optional but recommended.
4. Place on a microwave-safe plate. Do not wrap the potato in foil, which is unsafe in a microwave. You can place it on a paper towel to catch moisture.
5. Microwave on high. Cook for 3 minutes, then flip the potato over. This promotes even cooking.
6. Continue cooking. Microwave for another 2 to 4 minutes, depending on size and wattage.
7. Test for doneness. Carefully squeeze the potato with an oven mitt or towel. It should give slightly and feel soft. You can also insert a fork; it should slide in easily.
8. Let it rest. Let the potato sit for 1 to 2 minutes after cooking. Residual heat finishes the cooking process and makes the texture more even.
9. Serve. Cut open, fluff with a fork, and add your favorite toppings.

If the potato is still hard after the initial time, return it to the microwave in 30-second to 1-minute increments until done. Always test before adding more time to avoid overcooking.

Microwave Cooking Times by Size and Power

The table below gives approximate cooking times for a single small potato. Use these as starting points and adjust based on your microwave and potato.

These times assume the potato is at room temperature and cooked on high power with one flip halfway through. Always check for doneness before serving, since individual potatoes can vary.

Best Potato Varieties for Microwaving

Different potatoes give different results in the microwave. Choosing the right variety for your goal makes a big difference.

Russet Potatoes

Russets are the classic baking potato. They are starchy, with thick brown skin and a fluffy interior. A small Russet microwaves well and gives you that traditional baked potato texture. The skin can be a bit tough if not oiled, but the inside becomes light and airy.

Yukon Gold Potatoes

Yukon Golds are all-purpose potatoes with a buttery flavor and creamy texture. They microwave beautifully and hold their shape well. Small Yukon Golds are excellent for quick side dishes and taste great with just butter and salt.

Red Potatoes

Red potatoes are waxy with thin, edible skin. They stay firm after cooking and are ideal if you want a potato that holds together for slicing or salads. They cook quickly because of their moisture content.

Fingerling and New Potatoes

These are naturally small and cook very fast. Fingerlings have a firm, slightly waxy texture and a nutty flavor. New potatoes are harvested young and have thin, delicate skins. Both are excellent for microwaving, often needing only 3 to 5 minutes.

Purple and Blue Potatoes

These colorful potatoes are waxy and slightly nutty. They microwave well and retain their vibrant color. They are a fun choice for visual appeal and add antioxidants to your meal.

How to Check for Doneness

Knowing when a potato is done is just as important as knowing how long to microwave a small potato. Overcooked potatoes become dry and mealy, while undercooked ones are hard and unpleasant.

Here are the most reliable ways to check:

• Squeeze test: Using an oven mitt or folded towel, gently squeeze the potato. A done potato yields slightly and feels soft. An undercooked potato feels firm and resistant.
• Fork test: Insert a fork into the thickest part. It should slide in with little resistance. If you feel hard resistance, cook longer.
• Knife test: A thin paring knife should slide in and out smoothly. If it sticks, the center is not done.
• Temperature check: For precision, use an instant-read thermometer. A fully cooked potato reaches an internal temperature of about 205 to 210 degrees Fahrenheit (96 to 99 degrees Celsius).

If the potato is not done, return it to the microwave for 30 seconds to 1 minute at a time. Test again after each increment. This careful approach prevents overcooking.

How to Get Crispy Skin in the Microwave

One common complaint about microwaved potatoes is that the skin stays soft rather than crispy. While a microwave cannot truly crisp skin the way an oven or air fryer can, you can improve the texture.

First, dry the potato thoroughly after washing. Moisture on the skin creates steam, which softens it. Second, rub the skin with a little oil and coarse salt before cooking. The oil helps conduct heat and promotes browning. Third, after microwaving, you can place the potato in a hot oven or under a broiler for 3 to 5 minutes to crisp the skin. A toaster oven works well for this.

Another trick is to microwave the potato on a microwave-safe rack rather than a flat plate. Elevating the potato allows air to circulate around it, reducing sogginess. If you do not have a rack, a folded paper towel can lift it slightly.

Keep in mind that for a quick meal, soft skin is perfectly acceptable and still tastes good. Do not let the pursuit of crispy skin discourage you from using the microwave, which is primarily about speed and convenience.

Common Mistakes to Avoid

Even a simple task like microwaving a potato has pitfalls. Avoiding these common mistakes will improve your results dramatically. (See Also:How Long Cook Sweet Potato Microwave)

• Not poking holes: This is the most dangerous mistake. Steam builds up inside the potato and can cause it to burst, making a mess and potentially burning you. Always pierce the skin several times.
• Overcooking: Leaving the potato in too long dries it out and makes the texture mealy. Start with less time and add increments.
• Undercooking: Pulling the potato out too early leaves a hard center. Always test for doneness before serving.
• Wrapping in foil: Aluminum foil should never go in a microwave. It can spark and cause a fire. Use a microwave-safe plate or paper towel instead.
• Cooking too many at once: Overloading the microwave leads to uneven cooking. Cook in batches or increase the time carefully.
• Skipping the rest time: Cutting into the potato immediately can release steam and make the texture uneven. Let it rest for 1 to 2 minutes.
• Ignoring wattage: Using oven-baked potato times in a microwave leads to disaster. Always adjust for your microwave’s power.
• Not flipping: Failing to flip the potato halfway through can leave one side undercooked. Flip once during cooking.

Tips and Best Practices

These practical tips will help you get the most out of microwaving small potatoes.

• Use a microwave-safe cover: A vented microwave cover traps some steam for even cooking while preventing splatters.
• Cook potatoes of similar size together: This ensures they finish at the same time.
• Add a small bowl of water: Placing a cup of water in the microwave alongside the potato can help maintain moisture and prevent drying.
• Use the potato setting: Many microwaves have a built-in potato button. It works reasonably well but still benefits from a flip halfway through.
• Season after cooking: Salt and butter absorb better into a hot, freshly cut potato. Season the inside, not just the skin.
• Try the par-cook method: Microwave the potato for 3 minutes, then finish in a hot oven for 10 minutes. This gives you speed plus crispy skin.
• Store properly: Keep raw potatoes in a cool, dark, ventilated place. Do not refrigerate them, as cold temperatures convert starch to sugar and affect flavor.
• Batch prep: Microwave several small potatoes at once, then refrigerate. Reheat individually throughout the week for quick meals.

Serving Ideas for Microwaved Small Potatoes

A microwaved small potato is a versatile base for many meals. Here are some simple serving ideas.

• Classic baked potato: Split open, fluff with a fork, and top with butter, sour cream, chives, and shredded cheese.
• Loaded potato: Add crumbled bacon, cheddar cheese, sour cream, and green onions.
• Garlic herb: Toss hot potato chunks with butter, minced garlic, rosemary, and thyme.
• Potato salad base: Cool cooked potatoes, then toss with mayonnaise, mustard, celery, and pickles.
• Breakfast hash: Dice the cooked potato and fry with onions, peppers, and eggs.
• Soup thickener: Mash a microwaved potato and stir into soups for body and creaminess.
• Simple side: Serve with just butter, salt, and pepper alongside any protein.

Because small potatoes cook so quickly, they are ideal for single servings or small households. You can have a hot, satisfying side dish in under 10 minutes.

Storage and Reheating

If you have leftover cooked potatoes, store them in an airtight container in the refrigerator for up to 4 days. Let them cool to room temperature before refrigerating to prevent condensation.

To reheat a microwaved potato, place it on a microwave-safe plate and cook on high for 1 to 2 minutes. Cover it with a damp paper towel to retain moisture. You can also reheat in an oven at 350 degrees Fahrenheit for 10 to 15 minutes, which restores a better texture.

Avoid reheating potatoes more than once, as repeated heating degrades texture and flavor. If you plan to use leftovers in a salad or hash, cold potatoes often work better than reheated ones.

Frequently Asked Questions

Do I really need to poke holes in the potato?

Yes. Poking holes allows steam to escape during cooking. Without holes, pressure builds up inside the potato and it can explode, creating a mess and a safety hazard. Use a fork to pierce the skin 4 to 6 times before microwaving.

Should I wrap the potato in a paper towel?

You can, but it is not required. A damp paper towel helps retain moisture and promotes even cooking. A dry paper towel absorbs excess moisture. Both work fine. Avoid plastic wrap unless it is labeled microwave-safe.

How long to microwave two small potatoes?

For two small potatoes, add about 2 to 3 minutes to the single-potato time. In a 1000-watt microwave, that means roughly 8 to 10 minutes total. Arrange them in a ring and flip halfway through.

Can I get crispy skin in the microwave?

Not truly crispy. The microwave steams rather than bakes, so skin stays soft. You can improve texture by oiling and salting the skin, and you can finish the potato under a broiler or in a toaster oven for a few minutes to crisp it.

Should I use full power or 50 percent power?

Use full power for speed. However, if your potato is large or cooks unevenly, try 70 to 80 percent power for a longer time. Lower power cooks more gently and can produce a more even texture, though it takes longer. (See Also:How Long Sponge In Microwave)

Can I microwave a potato wrapped in foil?

No. Aluminum foil should never be placed in a microwave. It can spark, cause arcing, and start a fire. Always use microwave-safe dishes and coverings.

Why did my potato burst in the microwave?

Bursting usually happens because holes were not poked, or the potato was overcooked. Steam builds up inside with no way to escape. Always pierce the skin and monitor cooking time carefully.

How do I adjust for a cold potato from the fridge?

Add 1 to 2 minutes to the cooking time. Cold potatoes take longer because the microwave must first bring them to room temperature. For best results, let the potato sit out for 10 to 15 minutes before cooking.

Should I salt the potato before microwaving?

Salting the skin before cooking adds flavor and helps with texture. Salting the inside after cutting is also important. Avoid over-salting, as potatoes absorb salt readily.

What happens if I microwave a potato too long?

Overcooking dries out the potato, making it mealy and tough. The skin can become leathery. In extreme cases, the potato can burn or catch fire. Always start with less time and add increments.

Conclusion

So, how long to microwave a small potato? For most situations, the answer is about 5 to 7 minutes on high power in a standard 1000-watt microwave, flipping halfway through. Very small potatoes may need only 4 to 5 minutes, while slightly larger ones can take 7 to 9 minutes. Always adjust for your microwave’s wattage, the potato’s size and variety, and whether it is cold from the refrigerator.

The key to success is simple: wash, poke holes, microwave, flip, test, and rest. By starting with a conservative time and adding increments, you avoid both undercooking and overcooking.
