How to Make Caramelized Onion Mashed Potatoes
Follow these simple steps to prepare this delicious dish:
Step 1: Prepare the Potatoes
Start by peeling and chopping your Yukon Gold potatoes into evenly sized chunks. Place them in a large pot of cold salted water and bring to a boil over medium-high heat.
Step 2: Cook the Potatoes
Once boiling, reduce heat and let simmer until tender—about 15-20 minutes should do it. You can test doneness by poking them with a fork; they should crumble easily.
Step 3: Caramelize the Onions
While your potatoes are cooking, slice your sweet onions thinly. In a large skillet over medium-low heat, melt two tablespoons of butter. Add onions and season with salt; cook gently until they turn golden brown—this should take about 20-25 minutes, stirring occasionally.
Step 4: Mash It Up
Once your potatoes are tender, drain them thoroughly. Return them to the pot and add remaining butter, heavy cream, salt, and pepper. Mash until smooth and creamy.
Step 5: Combine Flavors
Now gently fold in those luscious caramelized onions into your potato mixture. Give it a taste—add more salt or pepper if needed!
Step 6: Serve Warm
Transfer your beautiful creation to a serving bowl and garnish with extra caramelized onions on top if desired. Feel free to serve alongside roasted meats or enjoy them straight from the bowl—no judgment here!
