What Are Oven Roasted Chestnuts? ❄️🌰
Roasted chestnuts are a winter treat enjoyed for centuries. Traditionally, chestnuts were roasted over an open fire in metal pans with holes, which gave them a smoky flavor. Oven roasting is a safe, convenient alternative that produces tender, flavorful nuts without the hassle.
With proper scoring and par-boiling, oven roasted chestnuts peel easily and taste just as comforting as the traditional method. Pair them with sage, butter, or other cozy winter flavors for a perfect snack or recipe addition.
Ingredients & Notes for Oven Roasted Chestnuts 📝
- Fresh chestnuts: Look for smooth, glossy shells and heavy weight. Avoid dried or hollow nuts.
- Butter (or vegan alternative): For browning with sage. Optional if you want classic roasted chestnuts.
- Fresh sage leaves: Adds a fragrant, warm flavor when browned in butter.
- Flaky sea salt: Sprinkled at the end for the perfect finishing touch.
Notes:
- Chestnuts roast best when scored on the rounded side with a sharp knife.
- You can adjust the butter and sage based on preference or omit for a plain version.
- Oven roasting allows you to enjoy chestnuts anytime, not just over an open fire.
How to Roast Chestnuts in the Oven 🔥🌰
1. Prepare the Chestnuts
Choose fresh, glossy chestnuts that feel heavy. Briefly soak them in boiling water to soften the shells and make scoring easier.
2. Score the Chestnuts ✂️
Cut an “X” on the rounded side of each chestnut using a sharp knife. Scoring makes peeling easier after roasting.
3. Roast the Chestnuts 🍂
Place the chestnuts on a rimmed baking sheet or cast iron pan, cut-side up, and roast at 400°F (204°C) for 15–20 minutes. Larger nuts may need a few extra minutes. You’ll know they’re done when the shells curl slightly and the nuts feel tender.
4. Make Sage Browned Butter (Optional) 🌿🧈
Melt butter in a skillet, add sage leaves, and cook until golden and fragrant. Pour over the roasted chestnuts for a warm, aromatic finish.
5. Serve Your Oven Roasted Chestnuts 🍽️
Transfer chestnuts to a dish, sprinkle with flaky salt, and cover with a towel for a few minutes to loosen the shells. Serve warm for best flavor.
Serving Suggestions for Oven Roasted Chestnuts 🍴

Notes & Tips for Perfect Roasted Chestnuts 📝
- Cover freshly roasted chestnuts with a towel to make peeling easier.
- Experiment with cinnamon, nutmeg, or other spices in the browned butter for seasonal variations.
- Always use care when scoring chestnuts — the shells can be tough and slippery.

Oven Roasted Chestnuts
Roasting chestnuts in the oven is quite a bit simpler than you might think! These are served with a drizzle of browned sage butter for extra flavor.
Ingredients
- 1 pound/454g fresh unshelled chestnuts
- 8 to 10 fresh sage leaves
- 3 Tablespoons/42g butter
- A hefty pinch of fleur de sel
Instructions
- Preheat oven to 400°. Bring a medium sized pot of water to a boil and turn off heat.
- Soak the chestnuts in the hot water for 1 minute then drain chestnuts and pat dry. (This softens the shells and makes them easier to score.)
- Using a sharp paring knife, carefully cut an X on the rounded side of each chestnut while holding them down firmly on a kitchen towel.
- Arrange the scored chestnuts in a single layer, X side up on a sheet pan or cast iron pan.
- Roast until the peel begins to curl up, about 15 to 20 minutes.
- Three minutes before the chestnuts are done, make the sage browned butter.
Make the Sage Browned Butter:
- Heat the butter and sage leaves in a medium sized skillet until bubbly. Reduce heat to low and let bubble until the mixture turns light brown and fragrant and the sage leaves are crispy (about 1 to 2 minutes).
- Remove chestnuts from the oven and place then X side up in a serving dish or platter. Pour the browned sage butter over making sure to get the sauce into the cracks of the chestnuts. Place a clean towel or napkin over the chestnuts and left sit for 2 to 3 minutes until the chestnuts are cool enough to handle.
- Season generously with salt and serve immediately.
Notes
Variations:
Omit sage browned butter if desired and serve chestnuts plain.
Use vegan butter for a vegan/dairy-free version.
Storage:
Chestnuts are best served warm but peeled chestnuts can be stored in an airtight container in the fridge for 3-4 days.

When I think of roasted chestnuts, I always think of New York for the holidays. This recipe sounds so delicious.
Megan Stevens says
I have not had good chestnuts since I went to Venice 20 years ago, where they were soft and warm like a baked potato inside. Does 20 minutes at 400 make them this soft? This is a beautiful recipe and the photography is very compelling. Thanks for sharing! I'd love to try the addition of sage and butter. Yummy.
