Step‑by‑Step Instructions for Keto Chicken Broccoli Casserole
Step 1: Sauté Broccoli
In a large skillet, melt 1 tablespoon of butter over medium heat. Add the chopped broccoli and cook for about 4 minutes until it turns bright green and is slightly tender. This vibrant color signals it’s ready! Once done, transfer the broccoli to a bowl and set aside to maintain its crispness.
Step 2: Cook Garlic and Reduce Cream
In the same skillet, add the remaining 2 tablespoons of butter and melt over medium heat. Toss in the minced garlic and sauté for 1 minute until fragrant. Stir in the heavy whipping cream and let it simmer, stirring occasionally, for 3 to 5 minutes until the sauce thickens slightly and becomes glossy.
Step 3: Add Cheeses and Season
Next, incorporate the grated Parmesan cheese and one-third of the shredded mozzarella into the thickened cream mixture. Stir until the cheeses melt completely, transforming the sauce into a creamy delight. Season with salt and pepper to taste, ensuring your Keto Chicken Broccoli Casserole is flavorful and balanced.
Step 4: Combine Ingredients
Return the sautéed broccoli to the skillet, along with your cooked chopped chicken. Gently mix everything together until well combined, ensuring that the broccoli and chicken are fully coated in the luscious cheese sauce. This step unites all the flavors, setting the stage for a comforting casserole.
Step 5: Broil Cheese
Transfer the combined mixture into a baking dish and sprinkle the remaining mozzarella cheese evenly on top. Preheat your broiler and place the dish under it for about 2 to 5 minutes. Watch closely as the cheese melts and bubbles beautifully, turning a lovely golden brown—this is when your Keto Chicken Broccoli Casserole is at its most tempting!
