How to Make Baked Potato Mashed Potatoes

  1. Peel 2 pounds of russet potatoes and cut them into 2-inch chunks.
  2. Place potatoes in a large pot, cover with cold salted water (about 1 teaspoon salt), and bring to a boil.
  3. Reduce heat and simmer for 15-20 minutes, or until potatoes are easily pierced with a fork.
  4. While potatoes cook, melt 6 tablespoons (3 ounces) of butter in a small saucepan over medium heat. Add 1/2 cup milk and heat until warm and melted, stirring occasionally.
  5. In a separate skillet, melt 2 tablespoons (1 ounce) of butter over medium heat. Add 2 large yellow onions, thinly sliced, and cook, stirring occasionally, until caramelized to a deep golden brown (about 20-25 minutes).
  6. Add 2 tablespoons of dry sherry to the caramelized onions and cook for 2 minutes, or until the liquid evaporates.
  7. Drain the cooked potatoes well.
  8. Add the warm milk and butter mixture to the potatoes and mash until smooth. Season generously with salt and pepper to taste.
  9. Stir in the caramelized onions.
  10. (Optional) Stir in 1/2 cup of grated Gruyère cheese or cheddar cheese.
  11. (Optional) Serve immediately, or keep warm until ready to serve. For individual servings add cheese and remaining ingredients directly to each dish.
  12. (Optional) If omitting cheese and sherry, top with your favorite gravy.

Chef's Tip for Extra Flavor

Want to unlock deeper, more complex flavors? Try toasting your whole spices before grinding them, or blooming ground spices in a little warm oil to enhance their aroma. Deglazing your pan with a bit of stock, wine, or even water after browning ingredients can capture those tasty caramelized bits, adding richness to your dish.
