How to Make Caramelized Onion & Gruyère Mashed Sweet Potatoes
Prepping those sweet potatoes: Begin by peeling and chopping four medium-sized sweet potatoes into even chunks. Place them in a large pot filled with salted water and bring it to a boil on high heat.
Cook until tender: Allow the sweet potatoes to simmer for about 15-20 minutes until they’re fork-tender—this means they should easily break apart when pierced.
Caramelizing onions: While your sweet potatoes are cooking, heat two tablespoons of butter in a skillet over medium heat. Add sliced onions and cook until they turn golden brown and fragrant—this usually takes around 15 minutes.
Mash those sweet potatoes: Drain your cooked sweet potatoes and return them to the pot. Add in caramelized onions (make sure you save some for garnishing), Gruyère cheese, heavy cream, salt, and pepper.
Mix it up: Using a potato masher or mixer, blend everything together until smooth but still a little chunky—this adds character! Taste and adjust seasoning as necessary; it’s important to get it just right.
Serve with flair: Transfer your mashed masterpiece into a serving bowl and sprinkle the remaining caramelized onions on top for that extra touch. Enjoy this creamy delight warm!
