Creamy mashed potatoes get a rich upgrade with the nutty aroma of browned butter and the earthy taste of just-fried sage. This side dish transforms a simple comfort food into something special for weeknight dinners or holiday tables.
The first time I tried brown butter in mashed potatoes was at a holiday dinner with friends. It turned a classic into the most requested side dish every year since.
Ingredients
- Yukon Gold potatoes: Bring a naturally creamy texture and buttery flavor that holds up well when mashed. Look for potatoes that feel firm and heavy with thin smooth skins.
- Unsalted butter: Essential for browning and lets the nutty flavor shine. Choose high quality butter as its taste is the star here.
- Whole milk and optional heavy cream: Add silkiness and richness. Warm them before adding to help your potatoes stay fluffy.
- Fresh sage leaves: Deliver a woodsy punch and subtle crisp texture. Choose leaves that are firm and vibrant green.
- Kosher salt and freshly ground black pepper: Balance and enhance all the flavors. Season as you go to build depth.
Instructions
- Prepare the Potatoes:
- Peel Yukon Gold potatoes and cut into even chunks to ensure smooth even cooking. Place them in a large pot and cover with cold salted water. Boil then simmer until fork tender which takes about fifteen to twenty minutes.
- Brown the Butter with Sage:
- While the potatoes cook melt unsalted butter in a small saucepan over medium heat. Add chopped fresh sage and let them sizzle. Watch closely swirling the pan until the butter becomes golden and aromatic with sage crisping up. Immediately remove from the heat to retain flavor and avoid any bitterness.
- Drain and Steam Off:
- Once the potatoes are soft drain thoroughly in a colander. Return to the hot pot and let them sit for one to two minutes to steam off extra moisture so your mash will be creamy not watery.
- Mash to Perfection:
- Use a sturdy masher or ricer to break up the potatoes. Work until completely smooth with no lumps remaining.
- Warm the Dairy:
- Gently heat the milk and cream if using so that adding them keeps the potatoes supple and hot. Pour this into the mashed potatoes.
- Combine and Finish:
- Pour in the browned butter sage mixture saving a little for topping. Add salt and pepper. Stir well until every bite is creamy and flecked with sage.
- Taste and Serve:
- Taste again for seasoning. Adjust with more salt or pepper as needed. Scoop into a serving bowl and spoon the reserved brown butter sage on top.

I love the way the butter sizzles around the sage filling the kitchen with a toasted aroma. My kids always hover by the stove hoping for crispy sage leaves as a snack before dinner is ready. These little details make it a recipe we cherish.
Storage Tips
Let leftovers cool fully before boxing them up in a shallow airtight container. Refrigerate up to three days. When reheating add a splash of milk and cover to keep them silky and moist. For longer storage freeze portions in ziptop bags and defrost in the fridge or gently in the microwave.
Ingredient Substitutions
Russet potatoes work if you prefer a fluffier finish. For dairy free needs use your favorite plant based milk and butter blend. Rosemary or thyme can sub for sage in a pinch but the flavor profile will change.
Serving Suggestions
This mash shines alongside roast chicken and holiday turkey but it is just as welcome with weeknight mushroom gravy. For added luxury top with extra herbs or a handful of crispy shallots. Sometimes I drizzle hot brown butter on top right before serving for a restaurant worthy flourish.
Cultural and Seasonal Notes
Mashed potatoes have roots in many cultures but brown butter and sage nod to both American comfort food traditions and classic Italian seasonings. In fall or winter always use hearty sage but in spring swap in chives or tarragon for a lighter twist.

Brown butter sage mashed potatoes are impressive yet comforting, guaranteed to make any dinner feel special. With a few simple techniques, you get maximum flavor in every spoonful.
