This Cocotte Onion Boil takes the viral Tiktok version and turns it into a cocotte personal side dish that buttery, seasoned and delicious.

The “onion boil” is a Tiktok viral, side dish that involves baking a whole onion (not actually boiling them) and then stuffing it with butter and spices. They come out soft, buttery and sweet. It gets its name from the heavy-seasoned, butter-drenched style typical of southern seafood boils. This version cooks the onion in a cocotte in all that delicious seasoned butter.

This recipe is apart of an ongoing series with Le Creuset where we reimagine recipes using their mini cocottes. This recipe reimagines how we make a baked brie takes advantage of all the benefits of doing it in a mini cocotte. Not only does it look great on a cheese board, but it allows us to bake cheese together, and to combine with honey and jam in one vessel.

Cocotte Onion Boil
Ingredients
- 1 medium sized sweet onion
- 3 tbsp butter, softened
- 2 tsp Old Bay seasoning
- 1 tsp Cajun seasoning
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp smoked paprika
- 1/2 tsp salt
- 1/2 tsp black pepper
Instructions
- Preheat oven to 275. Core the onion: Using a sharp paring knife, core the center of your onion to create a hollow well. Make sure to not go all the way through the other side or else your butter will leak and it won’t be as good.
- Stuff with butter: take 1 tbsp of softened butter and stuff it into the cavity of the onion, filling the hole all the way to the top. Add onion to cocotte.
- Make the seasoned butter: Melt the remaining 2 tbsp of butter. Stir in the seasonings, then pour the melted butter into the well in the center of the onion, allowing it to overflow into the mini.
- Bake for about an hour, or until the onion is super soft and the layers peel easily. Pour over some of the butter in the bottom of the cocotte. Top with chopped chives. Enjoy!
