How to Make Brown Butter Mashed Sweet Potatoes

Prepare Potatoes: Peel and dice 2 pounds of sweet potatoes into evenly sized 1-inch cubes for quick, uniform cooking. Rinse in cold water to remove excess starch.
Boil: Place potatoes in a large pot, cover with salted water, and bring to a gentle boil. Simmer 15–20 minutes until tender and easily pierced with a fork.
Brown Butter: Meanwhile, melt ½ cup unsalted butter over medium heat. Swirl occasionally until golden brown specks form and aroma turns nutty, about 3–4 minutes. Watch carefully to prevent burning.
Drain & Mash: Drain potatoes and return to warm pot. Add heavy cream, salt, and pepper. Mash until smooth and creamy, reaching a velvety texture without lumps.
Combine & Serve: Pour brown butter (and crispy sage if using) over mashed sweet potatoes. Fold gently to distribute color and flavor evenly. Serve hot, garnished with extra sage leaves.

Optional: Sprinkle chopped fresh parsley for color.

Expert Tips for Brown Butter Mashed Sweet Potatoes

Choose the right potatoes: Select firm, medium-sized sweet potatoes to achieve a creamy mash that won’t turn watery or grainy.
Watch the butter carefully: Brown butter can quickly go from nutty to burnt; swirl constantly and remove from heat just as it turns golden brown.
Don’t overcook potatoes: Boil until just tender to avoid mushy texture; perfectly cooked cubes mash smoothly without losing structure.
Mash while warm: Mash potatoes right after draining to keep them fluffy and ensure the cream and butter incorporate seamlessly.
Add seasoning gradually: Salt and pepper should be adjusted toward the end to balance the natural sweetness and rich brown butter flavor perfectly.
