Ingredients
Vegetables
- 16 ounces broccoli, coarsely chopped
- 4 cloves garlic, minced
Dairy
- 2 tbsp butter, divided
- 3/4 cup heavy whipping cream
- 1 1/3 cups shredded mozzarella, divided
- 1/3 cup grated parmesan cheese
Protein
- 1 1/2 lb cooked, chopped chicken (about 4 cups)
Seasoning
- Salt and pepper, to taste
Instructions
- Sauté Broccoli: Set a 10-inch ovenproof skillet over medium heat and add 1 tablespoon of the butter. Once melted, add the broccoli and sauté until bright green and just tender, about 4 minutes. Remove the broccoli to a bowl to set aside.
- Prepare Cream Sauce: Melt the remaining 1 tablespoon of butter in the same pan and add the minced garlic. Cook until fragrant, about 1 minute. Pour in the heavy whipping cream and bring to a simmer, cooking until the sauce is reduced and thickened, approximately 3 to 5 minutes.
- Add Cheese to Sauce: Stir in 1/3 cup of the shredded mozzarella and all of the grated parmesan cheese until melted and well combined. Season the sauce with salt and pepper to taste, enriching its flavor.
- Combine Ingredients: Stir the sautéed broccoli and the cooked, chopped chicken into the creamy cheese sauce. Evenly distribute the mixture in the skillet and then top it with the remaining 1 cup of shredded mozzarella cheese.
- Broil the Casserole: Preheat your broiler. Position the skillet about 6 inches from the heat source and broil until the cheese topping is bubbling and starting to brown, between 2 to 5 minutes depending on your broiler’s intensity. Keep a close eye to prevent burning.
Notes
- Use an ovenproof skillet to transition easily from stovetop to broiler without transferring the food.
- Feel free to swap mozzarella for another melty cheese like cheddar for a different flavor profile.
- Adding a pinch of red pepper flakes to the cream sauce can give this casserole a subtle kick.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
