Cooking Instructions

Follow these simple steps to prepare this delicious Buttermilk Mashed Potatoes with Crispy Onions:

Step 1: Prepare Your Potatoes

Start by peeling the potatoes and cutting them into even chunks. This ensures they cook evenly. Place them in a large pot and cover with cold water.

Step 2: Boil Until Tender

Bring the pot of water to a boil over medium-high heat. Add a generous pinch of salt and let those potatoes simmer away until tender—about 15-20 minutes should do it.

Step 3: Drain and Dry

Once tender, drain the potatoes thoroughly and return them to the pot over low heat for about a minute. This helps evaporate excess moisture so your mash will be creamy rather than watery.

Step 4: Mash It Up

Using a potato masher or ricer (because we’re fancy like that), mash those spuds until fluffy. Add in your butter and pour in that luscious buttermilk while mixing until well combined.

Step 5: Season to Perfection

Sprinkle in salt and pepper according to your taste buds’ desires. Give it one last mix before transferring to your serving dish.

Step 6: Top It Off

Finally, sprinkle those crispy onions generously on top just before serving so they stay wonderfully crunchy!

Transfer to plates and enjoy these Buttermilk Mashed Potatoes with Crispy Onions as an indulgent side dish that elevates any meal from ordinary to extraordinary!
