Steps
Before you start
- Preheat your oven to 400 °F (200 °C)
- Pat potatoes dry with a clean kitchen towel—excess moisture prevents browning
- Have your brown butter ingredients ready before you start roasting
Toss potatoes with oil and season
- Place the halved or quartered potatoes in a colander and rinse under cold running water, then pat completely dry with paper towels.
- Transfer to a large mixing bowl.
- Drizzle with olive oil, sprinkle with 1 tsp (6 g) kosher salt and ½ tsp (1 g) black pepper, and toss until every piece is lightly coated and evenly seasoned.

Ready when: Potatoes are evenly coated and glistening
Tip: Drying the potatoes is essential—any surface moisture will steam rather than caramelize during roasting.
Roast potatoes until goldenOven 400°F / 205°C
- Spread the potatoes in a single layer on a sheet pan, cut-side down.
- Roast in a preheated 400 °F (200 °C) oven for 28–32 minutes, stirring halfway through at the 15-minute mark.
- The potatoes are ready when the cut sides are deeply golden-brown and a fork or knife pierces the flesh with minimal resistance, but the pieces still hold their shape.

Ready when: Cut surfaces are golden-brown; flesh is tender when pierced
Tip: Don't skip the halfway stir—it ensures even browning on all sides. If your pan is crowded, the potatoes will steam; use two pans if needed.
Brown butter with sage and garlic
- While the potatoes finish roasting, melt the 4 tbsp (57 g) cold butter in a small heavy-bottomed saucepan over medium heat.
- Add the 3 smashed garlic cloves and the torn sage leaves.
- Watch closely, stirring frequently with a wooden spoon.
- The butter will foam, turn pale golden, then deepen in color as the milk solids toast.
- After about 5–6 minutes, you'll smell a rich, nutty aroma.
- The solids at the bottom should be golden-brown (not black).
- Remove from heat immediately and set aside.
- If using red pepper flakes, add them now.

Ready when: Butter is nutty-smelling and golden-brown; solids are toasted but not burnt
Tip: Browning butter happens fast—don't walk away. Once it smells nutty, it can burn in seconds. If you overshoot and the solids look black, discard and start again with fresh butter.
Toss hot potatoes with brown butter
- Transfer the hot roasted potatoes to a serving bowl or back to the large mixing bowl.
- Slowly pour the warm brown butter over the potatoes while gently tossing with a wooden spoon or rubber spatula.
- Make sure the garlic cloves and sage leaves are distributed throughout.
- Let the potatoes rest for 2–3 minutes off heat so they absorb the flavors and any excess butter settles.

Ready when: Potatoes are evenly coated; sage and garlic are visible throughout
Tip: Use the warm pan to toss so the butter stays emulsified. If the brown butter has cooled and separated, give it a brief stir over low heat to bring it back together.
Taste and adjust seasoning
- After resting, taste a potato.
- Add more salt or pepper as needed—brown butter is rich, so the potatoes may need a pinch more salt to stand out.
- Transfer to a serving dish and serve warm.

Ready when: Flavors are balanced to your taste
Tip: Don't skip this step—brown butter's richness can mask the potato flavor if underseasoned.
Good to know
Tips
- Brown butter is the star here—don't rush it or let it burn. The nuttiness develops over a few minutes of gentle heat, and the aroma tells you when it's ready.
- Keeping the potato skins on adds texture and flavor. If you prefer peeled potatoes, peel them before halving, but pat them extra dry afterward.
- For extra depth, add a squeeze of fresh lemon juice or a splash of good balsamic vinegar just before serving—the acidity cuts through the richness of the butter beautifully.
- This dish is best served immediately while the potatoes are still warm and the brown butter is fragrant. If making for a crowd, reheat gently just before serving.
Storage & reheating
Serve warm or at room temperature. Leftover roasted potatoes keep refrigerated in an airtight container for up to 3 days. Reheat gently in a low oven (300 °F / 150 °C) for 10–12 minutes, or reheat in a skillet over medium heat with a splash of water until warmed through. Freezing is not recommended, as the texture of roasted potatoes deteriorates.
Substitutions
- Fresh sage leaves → Fresh thyme or rosemary. Use the same amount. Both herbs work beautifully in brown butter and complement roasted potatoes. Rosemary has a stronger flavor, so you might use 1 tbsp (3 g) instead of 8 leaves.
- Baby potatoes (such as Yukon Gold, Red Bliss, or fingerling) → Waxy potatoes such as new potatoes or fingerlings, cut into 1- to 1.5-inch (2.5–4 cm) chunks. Avoid starchy potatoes like russets, which become fluffy and won't crisp on the edges. Waxy varieties hold their shape and develop a creamy center with crispy edges.
- Unsalted butter → Ghee or clarified butter. Use the same amount. Ghee already has milk solids removed, so you'll skip the browning step and simply warm it gently with the sage and garlic for 1 minute. The result is slightly different in flavor but equally delicious.
- Extra-virgin olive oil → Neutral oil such as grapeseed or avocado oil. Use the same amount. The brown butter will provide all the rich flavor, so a neutral oil works fine for the initial roast.
