Equipment
- Skillet
- Oven
- Peeler
- Large Pot
- Chef's Knife
- Wooden Spoon
- Baking Sheet
Ingredients
- 3 lbs yukon gold or russet potatoes peeled and chopped into chunks
- 2 Tbsp avocado oil
- 2 large yellow onions finely chopped
- 1 bulb garlic
- 1.5 cups buttermilk
- 2 cups parmesan cheese or to taste
- 3 Tbsp unsalted butter optional
- 1 tsp sea salt to taste
Instructions
- Start by adding the avocado oil to a large non-stick skillet and heat it to medium-high. Once hot, add the finely chopped onions and sprinkle liberally with sea salt. Cover the skillet to trap the moisture, allowing them to soften and release their liquid, stirring occasionally.
- After about 20 minutes, the onions will start to turn translucent and soften. Remove the cover and reduce the heat to medium or medium-low. Continue cooking, stirring often, until the onions turn golden brown and caramelized, which should take another 30 to 40 minutes.
- While the onions caramelize, prepare the garlic. Cut the top off the bulb, place it on a sheet of foil, drizzle with avocado oil, and wrap it tightly. Roast in a preheated oven at 400 degrees Fahrenheit for 35 to 45 minutes, or until the cloves are golden brown and tender.
- Once the garlic is cool enough to handle, squeeze the bulb over a cutting board to release the soft cloves. Chop them into smaller pieces and set aside.
- In a large pot, bring water to a boil. Peel and chop the potatoes into roughly equal-sized chunks and add them to the boiling water. Cook until they’re very soft when poked with a fork, about 15 to 20 minutes.
- Drain the potatoes in a colander and transfer them back to the pot. Ensure they are still hot, as this will help with the mashing process.
- Add the buttermilk, parmesan cheese, butter (if using), and sea salt to the hot potatoes. Mash thoroughly using a potato masher until you reach your desired consistency.
- Give the mashed potatoes a taste and adjust the seasoning with more sea salt or parmesan cheese if necessary. Finally, fold in the caramelized onions and chopped roasted garlic until well combined.
- Serve your creamy Caramelized Onion Roasted Garlic Buttermilk Mashed Potatoes hot with your favorite main dish. Enjoy the compliments!
Notes
- Tip 1: 3 pounds will be approximately six medium to large sized russet potatoes. Note that if you’re serving more than 8 people, going up to 5 pounds of potatoes may be a solid choice. Just be sure to adjust the amounts of the other ingredients as needed.
- Tip 2: You can use low-fat buttermilk if you’d like, but I use regular. You can replace the buttermilk with full-fat canned coconut milk if you don’t do fresh dairy.
