Super Easy Homestyle Buttermilk Mashed Potatoes

There is nothing better than fresh and fluffy homemade mashed potatoes.

But who really wants to take the time to make them from scratch? It usually involves peeling, cutting, boiling and finally mashing potatoes, which can feel like an eternity when all you want is potatoes. Like right now.

If you want fresh and fluffy homemade mashed potatoes in less than 10 minutes, then this recipe is for you!

{cause seriously, I am all about quick and easy}

There is no peeling, chopping, or boiling involved.

And yes, real potatoes ARE involved.

I love making these mashed potatoes for a quick and easy side dish that everyone will think you spent hours preparing. It pairs perfectly with grilled meats, meatloaf, ham, a spoon, or pretty much anything.

Start by washing 1 pound (about 5-6 medium) red potatoes and placing them in a microwave safe dish.

Do not pierce them with a fork. {resist the urge}

Make sure they are flat on the bottom, and not on top of each other.

Cover the dish with plastic wrap, and leave a little area for venting on the side. Make sure the plastic wrap is not touching the potatoes.

Microwave for 8 minutes.

Once they are done, carefully remove them from the microwave and remove the plastic wrap.

Almost done!

Don’t have buttermilk? Try using this buttermilk substitute…works every time!

If you like your potatoes super smooth, you can get out your hand blender and whip them till they are smooth. But personally I like those little bits of potato chunk here and there to add texture. Leaving the tender skins on the potatoes not only saves time, it boosts the taste and adds color to these hearty homestyle buttermilk mashed potatoes.

No more potato flakes, or powdered potatoes…mmm’ K? 

No excuses for not making fresh homemade mashed potatoes when they are this easy.

Get on it!

    This looks so delicious! I’m all about leaving the skin on mashed potatoes too. Must try this recipe soon 🙂 Great meeting you last weekend, Shawn!

    Love this quick way of making potatoes! And the buttermilk always adds something special to mashed potatoes.

    1. Shawn

      It really does add a little something extra. And with a quick buttermilk substitute, making these potatoes can be a snap!

  3. Stefanie @ Sarcastic Cooking

    You are so clever Shawn! I love this recipe. So quick and easy! And the buttermilk addition! Mmm!

  4. Rachel @ Baked by Rachel

    I use the microwave trick for fries and baked potato chunks – gives a nice fluffy interior. I’ll have to try this sometime when I don’t want to wait 30 min for mashed potatoes!

  5. Mystie @ Simple Pantry Cooking

    What a great way to do mashed potatoes in the summer when I don’t want to heat up the kitchen! I’ve never done potatoes in the microwave.

    We’re headed to the Farmer’s Market today; new potatoes will be on my list. 🙂
