I love this thanksgiving side dish because you can assemble it ahead of time and finish the baking just before your guests arrive. That way you can serve warm brussles sprouts and cheese alongside your other holiday favorites.

How to make These Baked Cheesy Brussels Sprouts

Step 1: trim brussels sprouts and dice onion

To begin, preheat oven to 425F. Trim the ends off the brussels sprouts and cut them into quarters or eiths depending on the size.

Then, dice the onion and mince the cloves of garlic.

Step 2: Saute Brussels sprouts

Add oil to a large saute pan and cook garlic and onions until they are soft and fragrant. Add the brussels sprouts to the pan and increase the heat to medium.

Next, saute the brussels sprouts for about 8 minutes tossing frequently. Season them with 3/4 tsp of salt and pour into a casserole dish.

Step 3: Prepare the gruyere cheese sauce

In the same large saute pan, melt butter over medium heat. Mix in the flour until a paste forms. Then, slowly pour in the heavy cream stirring constantly to make a roux.

Then, mix in the vegetable broth and half of the gruyere cheese. Sir the mixture until the cheese is completely melted and mixed into the sauce. Season the sauce with salt and pepper.

Step 4: Bake brussles sprouts with cheese

Pour the warm cheese sauce over the brussels sprouts in the casserole dish. Top the whole thing with more gruyere cheese and place in the oven to bake.

Bake at 425F for 25 minutes and serve immediately.

Storage and reheating

Once fully cooled, store cheesy brussels sprouts in their original casserole dish with a cover or in an airtight container. Store in the fridge for up to 5 days.

Reheat in the oven until warmed through or reheat individual portions in the microwave, air fryer or toaster oven.

Make this dish ahead of time

If you want to make this dish the day before thanksgiving, follow all of the step up until baking the dish. Then, cover the dish and place in the fridge until just before you are ready to eat. Follow baking instructions and add a few extra minutes to account for the fact that the dish was chilled.
