This Caramelized Onion Mashed Potatoes recipe can quickly become a family favorite. You’ll find that the cooking process is straightforward, consisting of boiling the potatoes, sautéing onions to golden perfection, and blending it all into a creamy mash. To set the stage, here’s what you will be needing.
What you’ll need
- 3 lbs Russet potatoes
- 2 tablespoons unsalted butter
- 1/4 cup half and half or sour cream
- 1 medium white onion, chopped (about 1.5 cups)
- 2 teaspoons minced garlic
- 2 tablespoons unsalted butter (divided)
- 1 tablespoon olive oil
- 1 teaspoon packed brown sugar
- 1 teaspoon low-sodium soy sauce
One option for a crispier texture might be to use an air fryer technique for the potatoes, which can yield delightful results.
Directions to follow


Start by peeling and chopping your Russet potatoes. Place them in a pot, cover with cold water, and bring everything to a boil over medium heat. Cook until the potatoes are soft, about 15-20 minutes.
Drain the potatoes well, then add the butter and half and half (or sour cream). Mash until creamy and season with salt and pepper to taste.
In a large skillet, heat the olive oil over medium heat. Add one tablespoon of butter and let it melt. Incorporate the minced garlic and chopped onions, sautéing until fragrant and translucent.
After about 5 minutes, add the second tablespoon of butter to the onions. Stir in until melted, and continue cooking until the onions are golden brown and caramelized, about another 10 minutes.
Add the brown sugar and soy sauce to your skillet, stirring until combined. Then, remove from heat.
Finally, stir in the caramelized onions into the mashed potatoes, melding those delightful flavors together. Serve right away, or allow to cool completely, then cover and store in the fridge for the next day.
Best ways to enjoy it
Caramelized Onion Mashed Potatoes can be enjoyed in various ways. They pair wonderfully with hearty dishes like beef stew or can accompany juicy meats like roasted chicken. For a complete meal, consider serving them alongside some green vegetables for a balanced plate. Small garnishes, such as fresh herbs or crispy bacon bits, can add an extra touch of flair when plating.
How to store & freeze
If you have leftovers, storing caramelized onion mashed potatoes is quite easy. Simply let them cool to room temperature, then place them in an airtight container in the fridge. They should be consumed within 3-4 days. For longer storage, they can be frozen for up to 3 months. When reheating, add a splash of milk or cream to restore creaminess.
Pro chef tips
- When caramelizing onions, patience is key! Low and slow results in beautifully brown, sweet onions without burning.
- Choose Yukon Gold potatoes for a creamier texture if desired. They’ll add an even richer flavor to your dish.
- If you’d like to incorporate even more flavors, try mixing in some cheese or herbs while mashing.
Creative twists
Feel free to play with flavors by adding different cheeses, like feta or goat cheese, or even incorporating roasted garlic into your potatoes. Another option is adding sautéed mushrooms along with the onions for an earthier flavor profile. The possibilities are endless!
