Ingredients
For the Casserole
- 4 cups cooked chicken breast, shredded or cubed
- 4 cups broccoli florets
- 2 tablespoons butter
- 3 garlic cloves, minced
- 1 cup heavy cream
- 4 ounces cream cheese, softened
- 1 cup chicken broth
- 1½ cups shredded cheddar cheese
- ½ cup grated parmesan cheese
- 1 teaspoon onion powder
- 1 teaspoon Italian seasoning
- Salt and black pepper to taste
Optional Toppings
- Extra shredded cheddar cheese
- Crushed pork rinds for crunch
- Chopped parsley
Equipment Needed
- Large skillet
- Mixing spoon or spatula
- 9×13-inch casserole dish
- Oven
Step 1: Prepare the Broccoli
Preheat your oven to 375°F (190°C).
Bring a large pot of water to a boil and blanch the broccoli florets for about 2–3 minutes until bright green and slightly tender.
Drain the broccoli and immediately rinse with cold water to stop the cooking process.
This step helps keep the broccoli vibrant and prevents it from becoming mushy during baking.
Step 2: Prepare the Chicken
If using freshly cooked chicken, cut or shred it into bite-sized pieces.
Rotisserie chicken works wonderfully in this recipe because it saves time and adds extra flavor.
Place the chicken and broccoli into a lightly greased casserole dish and spread evenly.
Step 3: Make the Creamy Sauce
In a large skillet over medium heat, melt the butter.
Add the minced garlic and cook for about 1 minute until fragrant.
Pour in the chicken broth and heavy cream, stirring gently.
Add the softened cream cheese and continue stirring until the sauce becomes smooth and creamy.
The cream cheese gives the sauce richness while helping it thicken naturally without flour or starch.
Step 4: Add the Seasonings and Cheese
Stir in the onion powder, Italian seasoning, salt, and black pepper.
Add 1 cup of shredded cheddar cheese and the parmesan cheese, stirring until melted and smooth.
The sauce should be creamy, cheesy, and slightly thickened.
Taste the sauce and adjust seasoning if needed.
Step 5: Assemble the Casserole
Pour the creamy sauce evenly over the chicken and broccoli in the casserole dish.
Gently stir everything together until fully coated.
Top with the remaining shredded cheddar cheese for a delicious golden cheesy layer.
If desired, sprinkle crushed pork rinds over the top for added crunch without extra carbs.
Step 6: Bake
Place the casserole in the preheated oven and bake for 20–25 minutes.
The casserole is ready when the cheese is melted, bubbly, and lightly golden around the edges.
For extra browning, broil for 2–3 minutes at the end of baking.
Watch carefully during broiling to avoid burning the cheese.
Step 7: Cool and Serve
Allow the casserole to rest for about 5 minutes before serving.
This helps the creamy sauce thicken slightly and makes serving easier.
Garnish with chopped parsley if desired.
Serve warm and enjoy the rich creamy flavor.
Why This Recipe Works for Keto
This casserole is naturally low in carbohydrates because it avoids traditional casserole fillers like rice, pasta, breadcrumbs, or potatoes.
Instead, healthy fats from cream cheese, cheddar cheese, butter, and heavy cream provide satisfying richness while keeping the dish keto-friendly.
Broccoli adds fiber and nutrients without significantly increasing carb count.

- Do not overcook the broccoli before baking.
