How to Make Caramelized Onion Mashed Potatoes

Phase 1 – Prep

Gather your ingredients to streamline cooking.
Thinly slice the white onions; this will help them caramelize properly.
Peel and quarter the Yukon gold potatoes, ensuring even cooking.
Prepare a pot of salted boiling water for the potatoes.

Phase 2 – Cook/Assemble

In a large skillet over medium heat, add 3 tablespoons of olive oil.
Once hot, add the sliced onions and 2 teaspoons of sea salt. Cook for about 25-30 minutes, stirring occasionally, until deeply caramelized and golden brown.
While the onions are cooking, boil the quartered potatoes in salted water for about 15-20 minutes, or until fork-tender.
Drain the potatoes and return them to the pot. Let them steam for a minute to remove excess moisture.
Add in the caramelized onions, 3 tablespoons of unsalted butter, and 1 cup of blended cottage cheese.
Using a potato masher, mix until the potatoes reach a creamy consistency.
Season with ½ teaspoon of ground black pepper, adjusting salt as needed.

Phase 3 – Serve

Transfer the mashed potatoes to a serving bowl.
Garnish with a sprinkle of black pepper and a drizzle of olive oil for visual appeal.
Enjoy warm as an unforgettable side dish with your favorite entrees.

Pro Tips for the Best Results

For extra creaminess, blend the cottage cheese until smooth before adding it to the potatoes.
Try substituting half the butter with Greek yogurt for a lighter, tangy flavor.
Store leftover mashed potatoes in an airtight container for easy reheating.
Use a ricer instead of a masher for an ultra-smooth texture.
Sauté onions slowly on low heat to enhance their natural sugars.

Common Mistakes to Avoid

One common mistake is overcooking the potatoes, leading to a gummy texture. This happens when potatoes are boiled too long. To fix this, check the potatoes with a fork; they should be tender but not falling apart.

Another error is not allowing the onions enough time to caramelize. Shortening the process leads to raw flavors in your dish. For perfect caramelized onions, let them cook down patiently, stirring occasionally over medium heat until golden and sweet.

Lastly, some may rush the mashing process, resulting in lumps in the potatoes. Mash the potatoes while they’re still hot for a fluffier texture, and don’t over-mix, or you risk gumminess!
