Why I Love These Crockpot Mashed Potatoes With Caramelized Onions
- It requires only 6 ingredients!
- The caramelized onions and garlic powder add so much flavor.
- The mashed potatoes are super light, airy, and fluffy.
- There is no boiling involved.
Ingredient Notes
Potatoes – I used russet potatoes but feel free to use any type of potatoes such as Yukon gold, red potatoes, or baby yellow potatoes.
Onions – I highly recommend using Vidalia onions for this recipe. Vidalia onions are nice and sweet and are my favorite for caramelizing.
Top Tips
- If you like your mashed potatoes super creamy, add a generous amount of heavy cream or whole milk.
- Take your time caramelizing the onions, it should take about 35-40 minutes while stirring frequently. I like to get started on the onions while the potatoes cook.
- Use salted butter instead of unsalted butter!
- Not a fan of sour cream? Use mascarpone cheese or cream cheese instead.
- Garnish with fresh chives.
Can I Make These On The Stovetop Instead?
Yes, of course. Follow this recipe for creamy mashed potatoes, and then top them off with caramelized onions! It’ll be just as good.
What Can I Serve This With ?
You can serve this with creamy smothered chicken thighs and honey roasted carrots for a restaurant-quality meal.
