What Is Brown Butter?
If you’ve never made brown butter before, prepare to become obsessed.
Brown butter is simply butter that’s cooked long enough for the milk solids to toast and caramelize. Instead of regular melted butter, you get a rich, nutty flavor that adds incredible depth to both savory and sweet dishes.
It’s a simple step that makes these mashed potatoes taste like something you’d order at a restaurant.
Brown Butter & Parmesan Mashed Potatoes
Prep Time: 15 Minutes
Cook Time: 35 Minutes
Total Time: 50 Minutes
Servings: 8-10
Ingredients
- 3 pounds Yukon Gold potatoes
- 1 stick (½ cup) butter
- ½ cup heavy cream
- ½ cup sour cream
- 1 cup freshly grated Parmesan cheese
- 3 garlic cloves, peeled
- Salt, to taste
- Freshly ground black pepper, to taste
- Fresh thyme, for garnish
Instructions
Step 1: Cook the Potatoes
Place the potatoes and garlic cloves in a large pot and cover with cold water.
Bring to a boil and cook until the potatoes are fork tender, about 20 to 25 minutes.
Drain well and allow the potatoes to sit for a few minutes so excess moisture can evaporate.
Step 2: Brown the Butter
While the potatoes cook, melt the butter in a skillet over medium heat.
Continue cooking until the butter becomes golden brown and develops a nutty aroma. Watch carefully, as brown butter can go from perfect to burnt rather quickly.
Remove from the heat.
Step 3: Mash the Potatoes
Mash the drained potatoes and softened garlic together until smooth.
Stir in the brown butter, heavy cream, and sour cream until fully combined and creamy.
Season generously with salt and black pepper.
Step 4: Bake
Transfer the mashed potatoes to a greased baking dish.
Use the back of a spoon to create decorative swirls across the surface.
Sprinkle the Parmesan cheese evenly over the top.
Bake at 400°F for 15 to 20 minutes, or until the Parmesan is melted and golden brown.
For an extra crispy crust, broil for 1 to 2 minutes at the end of baking.
Step 5: Garnish and Serve
Remove from the oven and garnish with fresh thyme.
Serve warm and watch them disappear.
Make-Ahead Instructions
One of my favorite things about this recipe is that it can be made ahead of time.
Prepare the potatoes through the assembly step and refrigerate, covered, for up to 2 days before serving.
When ready to bake, remove from the refrigerator while the oven preheats and bake as directed. You may need to add an extra 5 to 10 minutes of baking time if the dish is still chilled.
It’s the perfect side dish for stress-free holiday hosting.
