This casserole is pure comfort food at its finest. It brings together tender, cooked chicken and fresh broccoli in a creamy, cheesy sauce that feels like a warm hug on a plate. I find it perfect for busy weeknights when you want something hearty, filling, and easy to prepare. Plus, its rich flavors remind me of family dinners where everyone gathers around the table to enjoy something delicious and satisfying.
The key components include 3 cups of cooked, diced chicken breast and 3 cups of steamed broccoli florets, which add both protein and vibrant greens to the dish. The creaminess comes from 8 ounces of softened cream cheese blended with 1 cup of mayonnaise, giving the casserole a smooth, tangy base. To finish, there’s a delightful mixture of cheeses: 2 cups of shredded cheddar, divided, and 1/2 cup of grated Parmesan, which melt into a golden, bubbly topping. Together, these ingredients create a flavor profile that is creamy, cheesy, and rich, balanced by the freshness of the broccoli and lean chicken.
This recipe is simple to make and perfect if you don’t want to spend too much time cooking. Start by preheating your oven to 375 degrees Fahrenheit. Then, beat the cream cheese and mayonnaise until smooth. Combine the diced chicken, steamed broccoli, 1 cup of cheddar, and Parmesan cheese in the creamy base. Pour everything into a baking dish, sprinkle the remaining cheddar on top, and bake for about 20 to 22 minutes until bubbly and golden. Serve it warm, and you get a rich, comforting low-carb casserole. When you have leftovers, just store them in an airtight container in the fridge for up to four days.
This dish is perfect for chilly nights when you want something heartwarming and filling. It’s also a great choice for potlucks or family gatherings since it’s easy to make in larger quantities and sure to please a crowd. Whether you’re looking for a simple weeknight dinner or a comforting casserole to share, this recipe fits the bill beautifully.

Chicken Tips
When selecting chicken for this casserole, opt for boneless, skinless chicken breast for lean protein. It’s best if the chicken is already cooked and diced, which saves time and ensures even cooking throughout the bake. You can use leftovers from a roast chicken or quickly poach chicken breasts in lightly salted water until cooked through. Make sure to dice the chicken into small, uniform pieces to allow every bite to have chicken and broccoli mixed with the creamy cheese sauce. If you prefer, cooked shredded chicken works just as well and blends nicely with the steaming broccoli.
Options for Substitutions
- Swap chicken breast for cooked turkey breast or cooked shredded pork for variety
- Use cauliflower florets instead of broccoli for a milder taste and similar texture
- Replace cream cheese with Greek yogurt or sour cream for a tangier sauce
- Use mayonnaise alternatives like avocado mayo or plain yogurt for lighter options
- Switch cheddar to mozzarella or Monterey Jack for a different melting cheese
- Substitute Parmesan with Pecorino Romano or omit for a less sharp flavor
Watch Out for These Mistakes
One common mistake is not softening the cream cheese enough before mixing. If the cream cheese is too cold, it can cause lumps and make the sauce uneven, so be sure to let it sit at room temperature until smooth or soften it gently in the microwave. Another issue could be overcooking the casserole. Baking it for too long may dry out the chicken and broccoli, so aim for about 20 to 22 minutes until bubbly and golden. Finally, be careful with seasoning. Since the cheeses and mayonnaise are already flavorful, adding too much salt can overpower the casserole. Taste carefully if adding extra seasonings to avoid that common pitfall.
What to Serve With Keto Chicken Broccoli Casserole Bake?
This casserole pairs wonderfully with a crisp, fresh side salad tossed in a light vinaigrette to balance the richness of the dish. For added veggies, roasted asparagus or sautéed green beans make great companions. If you want something warm and soft, garlic mashed cauliflower or zoodles (zucchini noodles) work well to keep the meal low-carb and satisfying.
Storage Instructions
Store any leftover casserole in an airtight container in the refrigerator for up to four days. For longer storage, you can freeze the casserole for up to three months. To freeze, cover tightly with plastic wrap and aluminum foil or use a freezer-safe container. Reheat leftovers gently in the microwave or on the stovetop over low heat to keep the texture creamy and prevent drying out. Add a splash of milk or cream if needed to loosen the sauce while reheating.
