How to Make Brown Butter Mashed Potatoes Recipe
Step 1: Prepare and Boil the Potatoes
Start by bringing a large pot of water to a rolling boil. Meanwhile, scrub your red potatoes until they’re sparkling clean and chop them into roughly 1 to 2 inch pieces—this size cooks faster and keeps the texture perfect. Once your water is ready, gently add the potatoes, bring the water back to a boil, then reduce to medium heat and simmer. Keep an eye on them; they’ll need anywhere between 20 to 35 minutes depending on the size of your chunks. The test? When you can easily pierce them with a fork, you’re ready for the next step.
Step 2: Drain and Combine Flavorful Ingredients
Drain the cooked potatoes thoroughly and return them to the pot or transfer to a large bowl. Now comes the fun part—adding milk, sour cream, salt, pepper, minced garlic, onion powder, parsley, and Parmesan cheese. Each ingredient blends to create a harmonious flavor profile where creamy meets tangy and savory, preparing the mash for a luxurious texture and taste.
Step 3: Mash and Add Horseradish
Grab your favorite potato masher or hand mixer and start breaking down the potatoes with the other ingredients. The goal is smooth yet a bit rustic—think creamy with some small chunks to keep things interesting. Next, stir in horseradish sauce; start with one teaspoon and keep tasting until you hit the zing level you love. This little kick sparks life into the mash without overwhelming it.
Step 4: Brown the Butter to Perfection
Here’s where your Brown Butter Mashed Potatoes Recipe really shines. Place your butter in a skillet or pot over medium heat and stir gently every couple of minutes. The butter will foam and then slowly start turning a golden brown, releasing those tiny brown specks at the bottom and filling your kitchen with a warm, nutty aroma. This process requires attention, but it’s worth every second. Once perfectly browned, immediately transfer the butter into a bowl to stop it from cooking further.
Step 5: Finish and Serve
You have two options here: fold all that gorgeous brown butter directly into your mashed potatoes or serve it on the side for an inviting drizzle. I trust you’ll agree drizzling makes it feel extra special! No matter how you do it, the buttery richness combined with the spiced, creamy potatoes will blow your mind.
How to Serve Brown Butter Mashed Potatoes Recipe

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover Brown Butter Mashed Potatoes Recipe should be cooled to room temperature and then stored in an airtight container in the refrigerator. They last well for about 3 to 4 days and retain much of their fresh flavor and texture.
Freezing
If you want to freeze these mashed potatoes, do so before adding the brown butter drizzle. Store in a freezer-safe container, leaving some headspace for expansion. Properly wrapped or sealed, they will keep their quality for up to 2 months. When ready to use, thaw overnight in the fridge for best results.
Reheating
Reheat leftover mashed potatoes gently on the stovetop over low heat or in the microwave. Stir occasionally and, if needed, add a splash of milk to loosen the texture. Add fresh browned butter at serving time to revive that rich nutty essence and creamy texture perfectly.
FAQs
Can I use a different type of potato for this Brown Butter Mashed Potatoes Recipe?
Absolutely! While red potatoes are preferred for their creamy texture and slightly sweet flavor, Yukon Gold or Russet potatoes also work well. Just adjust cooking times accordingly since they have different moisture and starch levels.
What’s the best way to brown the butter without burning it?
Use medium heat and stir frequently. Keep a close eye on the butter as it melts and foams. Once it starts turning golden and you see brown specks forming, remove it from heat immediately to stop the cooking and avoid a bitter burnt taste.
Can I make this recipe dairy-free or vegan?
Yes, by swapping regular butter for a plant-based margarine or vegan butter and using almond milk or another non-dairy milk, you can make a dairy-free version. Just note that the flavor will change slightly without the richness of traditional dairy.
How much horseradish should I add?
It depends on personal taste! Start with one teaspoon, then taste and add up to five teaspoons if you want more of a bite. Horseradish adds a wonderful zing that cuts through the richness of the potatoes and butter.
Can I prepare these mashed potatoes ahead of time?
Yes, you can make the mashed potatoes a day ahead without the brown butter. Refrigerate and reheat gently, then prepare and drizzle the brown butter just before serving to keep its rich flavor and aroma.
