How to Make Low Carb Chicken Casserole with Cheese
Step 1: Prep the Ingredients
Preheat your oven to 375°F (190°C). If your chicken isn't already cooked, poach or bake the breasts until cooked through and shred with two forks. Chop the broccoli and cauliflower into bite-sized florets. Dice the onion and mince the garlic.
Step 2: Sauté Veggies
Heat olive oil in a large skillet over medium heat. Add the onion and sauté for 2-3 minutes until translucent. Toss in the garlic, broccoli, and cauliflower, cooking for another 5-7 minutes until just tender. Season with smoked paprika, dried thyme, salt, and pepper.
Step 3: Mix the Creamy Sauce
In a large bowl, combine the softened cream cheese, sour cream, and heavy cream. Stir in 1 cup of the shredded cheddar cheese until smooth and creamy.
Step 4: Assemble the Casserole
Add the shredded chicken and sautéed veggies to the creamy cheese mixture. Stir until everything is well combined. Pour the mixture into a greased 9x13-inch casserole dish and sprinkle the remaining ½ cup of cheddar cheese evenly on top.
Step 5: Bake to Perfection
Bake uncovered for 25-30 minutes or until the casserole is bubbly and the cheese is golden brown. Let it cool for a few minutes, garnish with fresh parsley, and dig in!
