Ingredients

  • 3 chopped onions
  • 2 lb cubed potatoes
  • 1 cup buttermilk
  • 1 cup water
  • 1 1/4 teaspoon salt
  • 1/8 teaspoon pepper

Instructions

  1. Combine all ingredients in a saucepan and simmer covered for 20 minutes or until the potatoes are tender.
  2. Drain, reserving the liquid.
  3. Add 3/4 cup of the reserved liquid to the potatoes and mash until smooth.
  4. Add more cooking liquid to thin the mixture if necessary.

Tips & Substitutions

For a creamier texture, consider substituting half of the buttermilk with sour cream. If you prefer a stronger onion flavor, sauté the onions in a bit of butter before adding them to the saucepan. Feel free to experiment with different types of potatoes; russets work well for mashing, while Yukon Golds offer a buttery flavor. This recipe is a great side dish for American recipes.

Serving Suggestions

Serve the oniony potatoes as a comforting side dish with grilled meats or roasted vegetables. They pair beautifully with a fresh salad or a hearty main like Spinach Romanoff. For a complete meal, consider adding a protein such as chicken or fish. Garnish with fresh herbs for an extra touch.

Storage & Reheating

Store any leftover mashed oniony potatoes in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a saucepan over low heat, adding a splash of water or buttermilk to ensure they don't dry out. Stir frequently until warmed through, or microwave in short intervals, stirring in between.
