Step‑by‑Step Instructions for Keto Chicken Cheese Bake
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This step is vital for ensuring your Keto Chicken Cheese Bake cooks evenly and achieves that delightful bubbly, golden top. Allow the oven to come to temperature while you prepare the ingredients, setting the stage for a scrumptious meal.
Step 2: Cook the Bacon
In a large skillet, cook the diced bacon over medium heat until it's crispy and golden, about 5-7 minutes. Once done, drain the excess fat, reserving about 2 tablespoons in the skillet for later use. Remove the bacon, crumble it, and set it aside to add that delicious smoky flavor to your dish later on.
Step 3: Prepare the Cream Sauce
In a medium saucepan, combine cream cheese, Parmesan, sharp cheddar, avocado mayonnaise, and heavy cream over medium heat. Stir continuously until the mixture is creamy and well blended, about 5 minutes. This rich cream sauce will form the flavorful base for the Keto Chicken Cheese Bake, ensuring every bite is packed with cheesy goodness.
Step 4: Sauté the Vegetables
Using the reserved bacon fat in your skillet, sauté the diced red onion for about 3 minutes, until it softens. Add the baby Bella mushrooms and continue cooking for another 5 minutes, stirring occasionally. Finally, add minced garlic and baby spinach, cooking just until the spinach wilts down, about 2-3 minutes.
Step 5: Combine Chicken and Sauce
In a large mixing bowl, gently combine the cooked rotisserie chicken, crumbled bacon, and the creamy sauce you prepared in Step 3. Stir until everything is evenly coated and well mixed. Then, pour this deliciously rich mixture into an 8x12-inch casserole dish, spreading it out evenly for optimal cooking.
Step 6: Add the Cheese Topping
Sprinkle shredded mozzarella cheese generously over the top of the mixture in the casserole dish. The mozzarella cheese will melt into a gooey layer, creating a satisfying texture for your Keto Chicken Cheese Bake. With the casserole assembled, it's time to send it to the oven.
Step 7: Bake to Perfection
Place the casserole in the preheated oven and bake for 20 minutes until the cheese is melted and bubbly. Keep an eye on it, as you want the top to be a lovely golden color. This baking process ensures that all the flavors meld beautifully together.
Step 8: Broil for a Golden Finish
For an extra touch, switch the oven to broil for an additional 1-2 minutes after baking. This will create a perfect browned crust on the cheese, making your Keto Chicken Cheese Bake look irresistibly enticing. Watch closely so it doesn't burn!
Step 9: Rest Before Serving
Once out of the oven, let the bake sit for 10 minutes. This resting period allows the flavors to meld together and the sauce to settle. As tempting as it is to dive right in, this step enhances the overall experience of your delicious Keto Chicken Cheese Bake.
