This recipe is all about the harmony of flavors and textures. The key players, like the yukon gold or russet potatoes, create a creamy base, while the buttermilk adds a tangy richness. The caramelized onions and roasted garlic bring warmth and depth, making each bite a comforting experience.

• 3 lbs yukon gold or russet potatoes – Peeled and chopped into chunks, these potatoes form the creamy foundation of the dish.
• 2 Tbsp avocado oil – This oil adds a light, nutty flavor and is perfect for cooking the onions.
• 2 large yellow onions – Finely chopped, they will caramelize beautifully, adding sweetness.
• 1 bulb garlic – Roasted until golden brown, it infuses the potatoes with rich flavor.
• 1 1/2 cups buttermilk – This creamy ingredient offers a slight tang, enhancing the overall taste.
• 2 cups parmesan cheese – Grated and mixed in, it adds a savory depth that’s hard to resist.
• 3 Tbsp unsalted butter – Optional, but it adds an extra layer of creaminess.
• 1 tsp sea salt – To taste, elevating and balancing the flavors.

How to Prepare Caramelized Onion Roasted Garlic Buttermilk Mashed Potatoes

Making Caramelized Onion Roasted Garlic Buttermilk Mashed Potatoes is a delightful journey of flavors. Follow these steps to create your own batch of comfort.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
