Ingredients for Caramelized Onion Mashed Potatoes
Gathering the right ingredients is key to making these Caramelized Onion Mashed Potatoes a hit at your dinner table. Here’s what you’ll need:
Russet potatoes: These starchy potatoes are perfect for mashing, giving you that creamy texture we all love.
Unsalted butter: Adds richness and flavor. Using unsalted allows you to control the saltiness of the dish.
Onions: Sweet, thinly sliced onions are caramelized to bring out their natural sugars, adding a deep, rich flavor.
Salt: Essential for enhancing the flavors of the potatoes and onions. I recommend using it in stages for the best results.
Black pepper: A dash of this adds a subtle kick that balances the sweetness of the onions.
Whole milk: This creamy addition makes the potatoes smooth and luscious. You can substitute with low-fat milk for a lighter version.
Sour cream: It adds a tangy flavor and creaminess that elevates the dish. Greek yogurt can be a great substitute if you’re looking for a healthier option.
Parmesan cheese (optional): For those who love a cheesy twist, this adds a savory depth. Feel free to skip it if you prefer a lighter dish.

How to Make Caramelized Onion Mashed Potatoes
Making Caramelized Onion Mashed Potatoes is a delightful journey that fills your kitchen with mouthwatering aromas. Follow these simple steps, and you’ll have a creamy, flavorful side dish that everyone will love!
Step 1: Prepare the Potatoes
Start by peeling and cutting your russet potatoes into chunks. This helps them cook evenly. Place the potato chunks in a large pot and cover them with cold water. Add 1/2 teaspoon of salt to enhance their flavor. Bring the pot to a boil over medium-high heat. Cook the potatoes until they’re tender, which usually takes about 15-20 minutes. Once they’re done, drain them and return them to the pot. This step is crucial for achieving that perfect creamy texture!
Step 2: Caramelize the Onions
While the potatoes are cooking, it’s time to caramelize the onions. In a large skillet, melt 2 tablespoons of unsalted butter over medium heat. Add the thinly sliced onions and sprinkle with 1/2 teaspoon of salt. Stir occasionally, allowing the onions to cook slowly. This process takes about 20-25 minutes, but trust me, the sweet, golden-brown onions are worth the wait. They’ll add a rich depth of flavor to your mashed potatoes!
Step 3: Mash the Potatoes
Once your potatoes are drained, grab a potato masher or a ricer. Mash the potatoes until they’re smooth and creamy. This is where the magic begins! The fluffier the mash, the better the dish will be. If you prefer a chunkier texture, feel free to leave some small lumps. It adds character to your Caramelized Onion Mashed Potatoes.
Step 4: Combine Ingredients
Now it’s time to bring everything together. Stir in the remaining 2 tablespoons of butter, whole milk, sour cream, and black pepper into the mashed potatoes. Then, fold in those beautifully caramelized onions. Mix until everything is well combined and creamy. If you’re feeling adventurous, add in the grated Parmesan cheese for an extra layer of flavor. It’s like a warm hug for your taste buds!
Step 5: Adjust Seasoning and Serve
Before serving, taste your mashed potatoes and adjust the seasoning with additional salt and pepper if needed. Serve them warm, and for a lovely presentation, garnish with extra caramelized onions on top. Your family and friends will be raving about these Caramelized Onion Mashed Potatoes long after the meal is over!
Tips for Success
Use a potato ricer for the fluffiest texture.
Don’t rush the caramelization; low and slow is key for sweet onions.
For extra creaminess, warm the milk before adding it to the potatoes.
Adjust the seasoning gradually; taste as you go!
Make ahead and reheat gently for a stress-free meal.
Equipment Needed
Large pot: Essential for boiling the potatoes. A Dutch oven works great too!
Skillet: A non-stick skillet is perfect for caramelizing onions.
Potato masher or ricer: Use a masher for a rustic texture or a ricer for fluffiness.
Measuring cups and spoons: Handy for precise ingredient measurements.
Variations
Garlic Mashed Potatoes: Add roasted garlic for a rich, savory flavor. Simply roast a head of garlic until soft and mash it into the potatoes.
Herbed Mashed Potatoes: Stir in fresh herbs like chives, parsley, or thyme for a burst of freshness and color.
Vegan Option: Substitute butter with olive oil and use plant-based milk and yogurt for a delicious vegan version.
Spicy Kick: Add a pinch of cayenne pepper or some chopped jalapeños for a spicy twist that will wake up your taste buds!
Cheesy Variation: Mix in different cheeses like cheddar or gouda for a cheesy delight that pairs perfectly with the caramelized onions.
Serving Suggestions
Pair with roasted chicken or grilled steak for a hearty meal.
Serve alongside steamed vegetables for a colorful plate.
Drizzle with a bit of olive oil or sprinkle fresh herbs for a beautiful presentation.
