Recipe Information
Ingredients
- 2 pounds Russet potatoes
- 6 tablespoons Unsalted butter
- 1 cup Whole milk
- 2 large Yellow onions
- 2 tablespoons Olive oil
- 1.5 teaspoons Salt
- 0.5 teaspoons Black pepper
- 1 teaspoon Fresh thyme leaves (optional)
Instructions
Peel the potatoes and chop them into evenly sized chunks, about 1.5 inches each. Rinse under cold water to remove excess starch.
Place the potatoes in a large pot and cover with cold water. Add 1 teaspoon of salt to the water. Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15-20 minutes or until the potatoes are fork-tender.
While the potatoes are cooking, prepare the caramelized onions. Peel and thinly slice the onions.
In a medium skillet, heat the olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for 20-25 minutes, or until the onions are golden brown and caramelized. Lower the heat slightly if the onions are browning too quickly.
Once the onions are caramelized, set them aside.
When the potatoes are done, drain them and return them to the pot. Let them sit for 1-2 minutes to evaporate any residual water.
Add the butter to the pot with the potatoes and mash using a potato masher or ricer until smooth. Stir in the milk a little at a time until the desired consistency is reached.
Season the mashed potatoes with 0.5 teaspoons of salt and 0.5 teaspoons of black pepper. Adjust seasoning to taste.
Fold in the caramelized onions and mix gently to combine. If desired, sprinkle the mashed potatoes with fresh thyme leaves for an herbal note.
Serve warm as a side dish and enjoy!
