Caramelized Onions Mashed Potatoes – jazz up the classic side dish by adding fragrant, sweet, caramelized onions to creamy mashed potatoes. The flavor is irresistible!
Served them with Baked Pork Chops or Instant Pot Tenderloin.
This dish is my comfort food lately: creamy mashed potatoes and sweet caramelized onions all in one side dish. Best combo ever! White onions, chopped fine, are sauteed with garlic in butter and olive oil combo. Once perfectly golden brown, sweet, fragrant and caramelized the onions are stirred into fluffy mashed potatoes. The onions add a whole new flavor to this classic side dish. It’s irresistible!
These Caramelized Onion Mashed Potatoes are a perfect way to jazz up plain mashed potatoes. The addition of perfectly caramelized onions take the spuds to a whole new level. You have to try this recipe!
Instructions:
- Start by peeling and chopping your potatoes. Place in a pot, cover with cold water, salt it and bring to a boil. Cook until potatoes are soft. Drain and mash with sour cream and butter. Season with salt and pepper to taste.
- Next, make caramelized onions: chop white onions and mince garlic. Heat up olive oil in a skillet, then add a tablespoon of unsalted butter. Melt. Add onions and garlic and saute until translucent, fragrant and some pieces are just starting to turn gold. Add another tablespoon of butter. Sautee onions until golden brown (see photo below for reference). Add soy sauce and brown sugar. Stir in. Remove onions from heat.
- Stir caramelized onions with mashed potatoes. Place in a serving dish. Garnish with chopped parsley, salt and pepper and serve.
Storing and reheating:
You can make the mashed potatoes and the onions a day ahead, then reheat and serve. You can reheat this dish in a skillet on the stove or place them in a casserole dish and reheat in the oven. Add milk or sour cream and butter as needed.

I will be serving baked salmon and are looking for a twist on the basic mashed potato recipe. I do like garlic mashed. Do you think the onions in the potat will go well with the salmon. Personally I love onions, just not sure about my guests.
Anna says
Hi Phil! I am a big fan of caramelized onions and I think this version of mashed potatoes will go great with salmon, chicken, pork chops, etc. You can always use the onions as a topping for the mashed potatoes, sort of make it an option for your guests. I hope you will give it a try! Enjoy!
