INGREDIENTS TO MAKE BRUSSELS SPROUTS CASSEROLE
- Brussels Sprouts
- Butter
- Olive oil
- Garlic
- Shallot
- All-purpose flour
- Milk
- Cream Cheese
- Salt + pepper
- Montery Jack cheese or Gruyere
- Mozzarella cheese
- Parmesan cheese
HOW TO MAKE BRUSSELS SPROUTS CASSEROLE
- Preheat oven to 375 degrees F. In a large frying pan over medium heat, combine the butter, oil, garlic, shallot, salt and pepper. Sauté until the shallots are tender, about 2-3 minutes. Add the brussels sprouts and stir to coat in the oil and butter. Cook until sprouts have softened, about 5 minutes.
- Remove the brussels sprouts mixture from the frying pan and set aside.
- In the same frying pan over low heat, melt the butter and once butter has turned frothy, whisk in the flour until it turns into a paste. Slowly pour in the milk and add the cream cheese whisking continuously ensuring no lumps form and the butter and flour are incorporated. Season with salt and pepper.
- Raise the heat to medium and continue to whisk until the mixture is simmering and small bubbles form. Stir in the cheeses until they have melted and the cheese sauce has thickened, about 5 minutes. The cheese sauce will coat the back of a wooden spoon when done.
- Add the cooked brussels sprouts to the cheese mixture and stir until all of the brussels sprouts are drenched in the cheese sauce. Pour into an 8 x 8 inch baking dish and top with more cheese!
- Bake for 15-20 minutes.
Look at all of that creamy goodness from the cheese sauce. The key to getting the brussels sprouts so soft making them pair with the melty cheese sauce so perfectly is sautéing the sprouts before. This side dish is so luscious and mouth-watering, you won’t believe you are eating veggies!
