When you’re craving comfort food but want to keep carbs in check, this Easy Low-Carb Chicken Casserole hits every note. Creamy, cheesy, deeply satisfying, and unbelievably simple, it’s the kind of dinner that makes everyone at the table happy—whether they’re following a keto lifestyle or not.

Casseroles have always been the unsung heroes of home cooking. They’re practical, forgiving, and designed to feed hungry families without requiring constant attention. This low-carb version stays true to that comforting tradition while swapping out carb-heavy ingredients for wholesome, keto-friendly alternatives that don’t sacrifice flavor.

What makes this recipe especially special is its versatility. It works just as well for busy weeknights as it does for meal prep Sundays. It reheats beautifully, freezes well, and adapts easily to whatever vegetables or cheeses you already have on hand. Even picky eaters tend to go back for seconds—always a good sign.

Why This Low-Carb Chicken Casserole Works

Many low-carb casseroles fall into one of two traps: they’re either too bland or overly complicated. This recipe avoids both.

First, it builds flavor in layers. Tender cooked chicken forms the hearty base. Lightly cooked broccoli adds texture and freshness. A rich, creamy sauce made with cream cheese and heavy cream brings everything together, while shredded cheese melts into a golden topping that seals in moisture and flavor.

Second, it’s intentionally simple. No specialty ingredients, no obscure keto flours, and no complicated techniques. If you can stir, pour, and bake, you can make this casserole.

Finally, it’s family-friendly. Even if you’re the only one eating low-carb, this dish doesn’t feel like “diet food.” It feels like real comfort food—because it is.

Ingredients

3 cups cooked chicken breast or thighs, shredded or cubed
2 cups broccoli florets, lightly steamed or blanched
8 oz cream cheese, softened
1 cup shredded cheddar cheese
½ cup shredded mozzarella cheese
½ cup heavy cream
2 cloves garlic, minced
1 tsp onion powder
½ tsp paprika
Salt, to taste
Black pepper, to taste
1 tbsp olive oil
Optional: chopped parsley or chives for garnish

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a medium casserole dish with olive oil.
In a large skillet over medium heat, warm the olive oil and sauté the minced garlic for about 30 seconds until fragrant.
Add the cream cheese and heavy cream to the skillet, stirring gently until the mixture becomes smooth and creamy.
Season the sauce with onion powder, paprika, salt, and black pepper. Stir well and remove from heat.
In a large mixing bowl, combine the cooked chicken and broccoli florets.
Pour the cream cheese sauce over the chicken and broccoli, mixing until everything is evenly coated.
Fold in half of the shredded cheddar and mozzarella cheese.
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 casserole is bubbly and the cheese is lightly golden.
Remove from the oven and let rest for 5 minutes before serving. Garnish if desired.

Tips for the Best Keto Chicken Casserole

Use rotisserie chicken to save time and add extra flavor.
Don’t overcook the broccoli before baking—it should stay slightly crisp.
Let it rest after baking so the sauce thickens naturally.
Shred your own cheese if possible; it melts better than pre-shredded varieties.

Easy Variations

Spicy version: Add red pepper flakes or diced jalapeños.
Bacon lovers: Stir in crispy chopped bacon before baking.
Extra veggies: Mushrooms, zucchini, or cauliflower work beautifully.
Different cheeses: Try Monterey Jack, Colby, or a sharp white cheddar.

Serving Suggestions
