How to Make Keto Chicken Broccoli Casserole Step by Step
Now for the fun part – let’s get cooking!
Step 1: Prepare the Chicken and Broccoli
Preheat your oven to 375°F (190°C). In the meantime, cut your chicken breasts into bite-sized pieces. Steam the broccoli until tender-crisp(about 5 minutes). After you are done steaming the broccoli, it is important to allow it to cool before adding it to the other ingredients; this prevents the casserole from getting watery. After it cools, set aside.
Step 2: Make the Creamy Cheese Sauce
In the same pan you used for the Broccoli, melt 2 tablespoons of butter over medium heat. Stir in 1/4 cup of almond flour and cook until fragrant and lightly browned (about 1 minute). Gradually whisk in 2 cups of heavy cream and 1 cup of shredded cheddar cheese, stirring until smooth and creamy like a velouté. Season with salt, pepper, garlic powder, and onion powder (around half a teaspoon of each). This is the key to the rich taste of this delicious dish.
Step 3: Combine and Assemble
Add the cooked chicken and broccoli to the cheese sauce; gently stir until combined. Pour the mixture into your prepared 9×13 inch baking dish.
Step 4: Bake the Casserole
Bake for 25-30 minutes, or until the casserole is bubbly and golden brown. Alternatively, you could opt for a low-temperature, long cooking technique that yields a more thorough integration of flavors.
Let it cool for at least 10 minutes before serving. This minimizes the risk of burns and ensures that the flavors meld together harmoniously.

Chef Kima’s Quick Fixes
