4 Tablespoons Salted Butter – Adds a rich, buttery flavor that makes the mashed potatoes irresistibly creamy.

¾ Cup Half & Half or Full-Fat Coconut Milk or Dairy-Free Milk – This creates a dreamy texture. Choose dairy-free milk for a vegan option.

1 Teaspoon Kosher Salt – Essential for seasoning, this salt enhances the flavors of the dish.

1 Cup Parmesan Cheese – Freshly grated for the best flavor and a cheesy kick that complements the sweetness of the onions.

1 Bunch Chives – Finely chopped for garnish, they add a burst of color and a mild onion flavor that brightens the dish.

How to Make Best Ever Caramelized Onion Mashed Potatoes

Follow these simple steps to prepare this delicious Best Ever Caramelized Onion Mashed Potatoes:

Step 1: Slice the Onions
Peel and thinly slice the onions, ensuring they are uniform in size for even caramelization. Set them aside for the next step.

Step 2: Caramelize the Onions
In a skillet over medium heat, add the olive oil and the sliced onions. Stir them occasionally, allowing them to cook until they become beautifully browned and caramelized, roughly 40-50 minutes. Patience is key here, so resist the urge to crank up the heat.

Step 3: Prepare the Potatoes
While your onions are getting their golden glow, wash and chop the Yukon Gold potatoes into small, even pieces. This helps them cook evenly and mash easily.

Step 4: Boil the Potatoes
Bring a large pot of salted water to a rolling boil. Carefully add your chopped potatoes and let them cook for 20 minutes or until fork-tender. No one likes undercooked potatoes, so stick a fork in and check for doneness.

Step 5: Mash the Potatoes
Drain the potatoes and return them to the pot. Mash them until they’re creamy and smooth, then stir in the butter, kosher salt, and half & half (or non-dairy milk) until well combined.

Step 6: Combine It All
Stir half of the caramelized onions into the mashed potatoes along with the grated parmesan cheese. Mix until everything is incorporated. This is where the magic happens.

Finish by transferring your creamy concoction to a large serving bowl. Arrange the remaining caramelized onions on top, sprinkle with chopped chives, thyme, and sage, and drizzle with melted butter for an extra touch of decadence. Serve these Best Ever Caramelized Onion Mashed Potatoes with pride, because you’ve turned a humble dish into a masterpiece that your family and friends will rave about!
