Why This Low-Carb Chicken Casserole Works

Casseroles have been a staple in family kitchens for generations, and for good reason. They’re economical, filling, and easy to scale. Traditional versions often rely on pasta, rice, or breadcrumbs — all high in carbs. This keto chicken casserole skips those fillers and replaces them with nutrient-dense, low-carb ingredients that still deliver comfort.

Key advantages:

High in protein, keeping you full longer
Naturally gluten-free
Kid-friendly flavors
One-dish meal = easy cleanup
Ideal for keto and low-carb lifestyles

The creamy base binds everything together, while the cheese topping creates that irresistible baked finish.

Ingredients

3 cups cooked chicken breast, shredded or diced
1 ½ cups broccoli florets, lightly steamed
1 cup shredded cheddar cheese
½ cup shredded mozzarella cheese
4 oz cream cheese, softened
½ cup heavy cream
2 cloves garlic, minced
1 tbsp olive oil
½ tsp salt
½ tsp black pepper
½ tsp paprika
¼ tsp onion powder
Optional garnish: fresh parsley

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a medium casserole dish with olive oil.
In a large mixing bowl, combine softened cream cheese and heavy cream. Mix until smooth and creamy.
Stir in garlic, salt, black pepper, paprika, and onion powder until evenly combined.
Add the cooked chicken and broccoli to the bowl. Toss gently until fully coated in the creamy mixture.
Fold in half of the shredded cheddar and mozzarella cheeses.
Transfer the mixture to the prepared casserole dish and spread evenly.
Sprinkle the remaining cheese evenly over the top.
Bake uncovered for 25–30 minutes, or until the cheese is melted and bubbly with lightly golden edges.
Remove from the oven and let rest for 5 minutes before serving. Garnish with fresh parsley if desired.

Tips for the Best Keto Chicken Casserole

Use rotisserie chicken to save time and add flavor.
Soften cream cheese fully before mixing to avoid lumps.
Don’t overcook broccoli — it should be just tender before baking.
Let it rest after baking so it sets and slices cleanly.

Easy Variations

Cheesy Bacon Version
Add ½ cup cooked, crumbled bacon for smoky richness.

Spicy Kick
Mix in crushed red pepper flakes or diced jalapeños.

Veggie Swap
Replace broccoli with cauliflower, zucchini, or spinach.

Extra Creamy
Add ¼ cup sour cream for an even richer texture.

Serving Suggestions

This casserole is hearty enough to stand alone, but it pairs beautifully with:

A simple green salad with olive oil dressing
Roasted asparagus or green beans
Cauliflower rice for a fuller meal

For family dinners, serve it straight from the baking dish — it’s cozy, casual, and inviting.

Meal Prep & Storage

Refrigerator: Store in an airtight container for up to 4 days
Freezer: Freeze individual portions for up to 2 months
Reheat: Warm in the oven at 325°F or microwave until heated through
