How to Make Best Ever Caramelized Onion Mashed Potatoes

Step 1: Prepare the Onions

To make these mashed potatoes, start by prepping your onions. Peel off the skin and thinly slice them. It may seem like a lot of onions at first, but remember—they will shrink down significantly as they cook!

Step 2: Caramelize the Onions

Heat a skillet over medium heat and drizzle in your olive oil. Once hot, add those sliced onions. Stir occasionally as they cook down for about 40-50 minutes until they turn golden brown and sweetly fragrant. This slow cooking process brings out their natural sugars, creating that beautiful caramelization.

Step 3: Cook the Potatoes

While your onions are caramelizing away, let’s get those Yukon Gold potatoes ready! Wash them thoroughly and chop them into small pieces—no need to peel unless you prefer it that way. Place them into a pot of boiling water and let them cook for about 20 minutes until fork-tender.

Step 4: Mash the Potatoes

Once your potatoes are cooked through, drain them well and return them to the pot. It’s time to mash! Add in your butter, kosher salt, and half & half (or coconut milk) before mashing again until everything is smooth. This step is crucial for achieving that creamy texture we all love.

Step 5: Combine Onions with Potatoes

When your onions are beautifully caramelized, remove half of them from the skillet and add them directly into your mashed potatoes along with freshly grated parmesan cheese. Stir well so everything gets nicely incorporated.

Step 6: Serve It Up!

Transfer your mashed potato mixture into a large bowl. Top it off with the remaining caramelized onions along with chives, thyme, sage, and a drizzle of melted butter if you like! Now you’re ready to serve up this delicious side dish—enjoy every bite!

Pro Tips for Making Best Ever Caramelized Onion Mashed Potatoes
