How to Make Best Ever Caramelized Onion Mashed Potatoes

Step 1: Prepare the Onions

To make these mashed potatoes, start by peeling the skin from the onions and thinly slicing them. It may look like a lot of onions, but trust me—it’s worth it! The sweetness that develops during caramelization adds incredible depth to your mashed potatoes.

Step 2: Caramelize the Onions

Heat a skillet over medium heat and add in the olive oil. Once hot, toss in those sliced onions. Stir occasionally as they cook down until they become beautifully browned and caramelized—this process usually takes about 40-50 minutes. Patience here pays off; those sweet flavors will transform your dish!

Step 3: Cook the Potatoes

While your onions are cooking away, wash your Yukon Gold potatoes thoroughly and chop them into small pieces—no need to peel unless you prefer it that way! Next, bring a pot of water to a rolling boil and add in your chopped potatoes. Let them cook for about 20 minutes until fork-tender.

Step 4: Mash It Up

Once your potatoes are done cooking, drain them well before mashing them in a large bowl. Add in the salted butter, kosher salt, and half & half (or coconut milk). Mash until everything is creamy and smooth—this is where you get that dreamy texture!

Step 5: Combine Onions with Potatoes

When your onions are perfectly caramelized, remove them from heat. Add half of them directly into your mashed potatoes along with freshly grated parmesan cheese. Stir well to ensure everything is fully incorporated—the cheesy goodness mingling with sweet onion flavors is pure magic!

Step 6: Serve!

Transfer those luscious mashed potatoes into a serving bowl. Top with the remaining caramelized onions, chopped chives, thyme, sage, and drizzled melted butter. Now it’s time to serve! Enjoy every bite—you’ve just created something truly special!

Pro Tips for Making Best Ever Caramelized Onion Mashed Potatoes

Making mashed potatoes can be a simple task, but a few tips can elevate your dish to the next level. Here are some tried-and-true suggestions to ensure your Best Ever Caramelized Onion Mashed Potatoes turn out perfectly every time.

• Use Yukon Gold Potatoes: These potatoes have a creamy texture and buttery flavor, making them an excellent choice for mashed potatoes. They hold up beautifully when mashed and create a rich, satisfying dish.

• Don’t Rush the Onions: Caramelizing onions takes time, usually around 40-50 minutes. Patience is key! Slow cooking brings out their natural sweetness and adds depth of flavor to your mashed potatoes.

• Warm Your Dairy: Before adding half & half (or coconut milk) and butter to your potatoes, warm them slightly. This helps everything blend more smoothly and keeps your mash fluffy rather than gummy.

• Season in Layers: Be sure to season at different stages—add salt while cooking the potatoes and again when mixing in the butter and dairy. This ensures an evenly flavored dish without any bland bites.

• Experiment with Herbs: While this recipe calls for thyme and sage, feel free to mix it up! Fresh parsley, rosemary, or even a hint of dill can add unique flavors that complement the caramelized onions beautifully.
