This cheesy chicken broccoli casserole is a stunningly easy and delicious keto dinner recipe. It comes together in 25 minutes and has less than 5g net carbs per serving!
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.
Melt the remaining butter in the pan and add the garlic, cooking until fragrant, about 1 minute. Add the cream and bring to a simmer, then cook until reduced and thickened, 3 to 5 minutes.
Stir in 1/3 cup of the mozzarella and all of the Parmesan until melted. Season with salt and pepper to taste.
Stir in the broccoli and the chicken and top with the remaining 1 cup of mozzarella cheese.
Preheat the broiler. Set the pan about 6 inches from the heat and broil until the cheese is beginning to brown, 2 to 5 minutes (depends on how intense your broiler is!).
