Notes and variations
- Potatoes. You can use most types of potatoes for this recipe. Russet potatoes and yukon gold potatoes are some of the potatoes that work really well for mashed potatoes. This recipe also works well with sweet potatoes and yam.
- Milk. I used whole milk for this recipe, but you can also use skimmed milk with a 1:1 ratio. Alternatively, you can also opt to use dairy-free milk. To achieve a creamier mashed potato, use half and half or heavy cream. Check out this detailed post on substitutes for milk in mashed potatoes for other options.
- Butter. You can use either salted or unsalted butter for this recipe. You can also substitute butter with margarine to make it vegan.
- Chopped fresh herbs. Level up your microwave mashed potatoes by adding fresh herbs such as fresh parsley, rosemary, sage, dill, or basil.
- Add cheese! If you thought mashed potatoes couldn't get any better, wait until you add cheese. You can use sharp cheddar, parmesan, or Swiss cheese.
- Add more seasonings of your liking such as roasted garlic, caramelized onions, garlic powder, or chili flakes.
📖 How to make microwave mashed potatoes
Place the chopped potatoes in a microwave-safe bowl and add enough water to cover the potatoes.
Microwave on high for 8-10 minutes, or until the potatoes are tender and can be easily pierced with a fork.
Drain the water from the potatoes and add the milk and two tablespoons of butter.
Use a potato masher or fork to mash the potatoes until they are smooth and creamy. If you prefer a smoother consistency, you can use a hand blender or food processor to puree the potatoes.
Season the mashed potatoes with salt and pepper to taste.
If desired, top the mashed potatoes with chopped fresh herbs or grated cheese and serve!
👩🏽🍳 Tips for the best microwave mashed potatoes
To make microwave mashed potatoes the perfect way, make sure to follow these expert tips!
- Soak the chopped potatoes in water for a couple of minutes, drain the water, and pat them dry before cooking. This will help remove excess starch and make your mashed potatoes fluffier.
- Cut the potatoes into smaller chunks. If you want to cook the potatoes a bit faster, you can cut them into even smaller chunks.
- Use a medium to large microwave-safe bowl. Make sure that the bowl is big enough that it will only be ½ to ⅔ full once it is filled with potatoes and water to prevent any spills in your microwave.
- Use a potato masher. While you can always use a fork, you'll have an easier time mashing the potatoes if you have a potato masher in hand. Better yet, use a potato ricer, hand mixer, or food processor for a smoother consistency.
- Microwave wattage. Check on the potatoes after five minutes to see whether they are tender enough. After cooking for eight minutes and potatoes are still not tender, continue to microwave and check every 30-second increments.
- Use oven mitts when removing the potatoes from the microwave as the bowl can get hot!

- Cut the potatoes into even pieces. This will help them cook evenly in the microwave.

Hey Dan! Typically you want to cover the chopped potatoes with water, but depending on the starchiness of the potato you're using, it might be helpful to add a small amount of water at the bottom as well. Hope that helps!
