Step-by-Step Instructions
Step 1: Prepare the Chicken
You can use freshly cooked chicken or leftover roasted chicken. I often roast mine with olive oil, salt, and pepper at 375°F until fully cooked.
Dice into bite-sized pieces.
Shortcut: Rotisserie chicken works beautifully here.
Step 2: Cook the Bacon
Cook bacon in a skillet until crisp. Drain on paper towels and crumble once cooled.
Reserve one tablespoon of bacon grease for extra flavor if desired.
Step 3: Lightly Steam the Broccoli
Steam broccoli for 3–4 minutes until slightly tender but still bright green.
You don’t want it mushy — it will finish cooking in the oven.
This keeps the low carb chicken casserole from becoming watery.
Step 4: Make the Cream Sauce
In a saucepan over medium heat:
- Add heavy cream and cream cheese.
- Stir until smooth.
- Add sour cream, garlic, onion powder, paprika, salt, and pepper.
- Simmer gently for 3–4 minutes until thickened.
The sauce should be creamy and rich but not overly heavy.
Step 5: Assemble the Casserole
Preheat oven to 375°F (190°C).
In a large mixing bowl, combine:
- Diced chicken
- Steamed broccoli
- Half of the bacon
- Cream sauce
Mix gently until coated.
Transfer to a greased 9×13 baking dish.
Top with cheddar, mozzarella, and remaining bacon.
Step 6: Bake
Bake uncovered for 25–30 minutes until:
- Cheese is melted
- Top is bubbly and lightly golden
For extra crispiness, broil for 2–3 minutes at the end.
Let rest 5–10 minutes before serving.
