Some nights, you just want dinner to feel like a warm blanket. This Keto Chicken Broccoli Casserole is exactly that kind of meal—comforting without the carb overload, creamy but not heavy, and packed with flavors that settle in just right. It’s the kind of dish you can make ahead and trust to deliver when the day has been a little too much.
I remember the first time I made this casserole. The kitchen smelled like melted cheese mixed with garlic and a hint of something buttery, but I was half-distracted by a phone call that ran longer than expected. When I finally pulled it from the oven, the edges were golden and bubbly, the broccoli perfectly tender but still bright. I sliced a piece and nearly burned my tongue because I couldn’t wait. There was this cozy creaminess that wrapped around every bite, with the chicken giving it a solid, hearty backbone. It wasn’t fancy, but it was exactly what I needed that evening.
- Combines simple ingredients into a creamy, satisfying low-carb meal.
- Comfort food vibes without the guilt of heavy carbs.
- It’s simple — and that’s kind of the point; no fuss, just good food.
- Great for leftovers, though the texture changes a bit if frozen.
If you’re curious about how flexible this casserole can be, you’ll be happy to know it’s pretty forgiving. I usually swap out broccoli for cauliflower or mix in some sautéed mushrooms when I have them on hand. It’s a good base to experiment with, and somehow it always feels like a meal worth savoring.

Ingredients
3 cups cooked chicken breast, shredded
4 cups fresh broccoli florets
1 cup shredded cheddar cheese
1 cup shredded mozzarella cheese
1/2 cup cream cheese, softened
1/2 cup sour cream
1/4 cup mayonnaise
1/4 cup grated Parmesan cheese
1/2 cup heavy cream
2 cloves garlic, minced
1 teaspoon onion powder
1/2 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons olive oil
Instructions
Preheat the oven to 375°F (190°C).
Bring a large pot of water to a boil. Add the broccoli florets and cook for 2-3 minutes until bright green and slightly tender. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
In a large mixing bowl, combine cream cheese, sour cream, mayonnaise, heavy cream, onion powder, salt, and black pepper. Mix until smooth.
Add shredded chicken, cooked broccoli, cheddar cheese, mozzarella cheese, and half of the Parmesan cheese to the bowl. Stir until all ingredients are evenly coated with the sauce.
Transfer the mixture to a greased 9×13 inch casserole dish and spread evenly.
Sprinkle the remaining Parmesan cheese evenly over the top.
Bake in the preheated oven for 25-30 minutes, until the casserole is bubbly and the cheese is golden brown.
Remove from the oven and let it cool for 5 minutes before serving.
When it comes to kitchen gear, nothing fancy is required here—just a good oven-safe dish and a skillet to bring the flavors together. This casserole shines best fresh from the oven, but leftovers reheat well in the microwave or oven, just keep an eye on it so it doesn’t dry out. Try pairing it with a crisp green salad or some roasted garlic asparagus if you want to round out the meal. Variations can be as simple as swapping cheeses or adding a pinch of smoked paprika for a subtle smoky twist—though I haven’t tested all of these, so feel free to experiment.
FAQ

Is this recipe suitable for meal prep? Definitely. It keeps well in the fridge for a few days, making weekday dinners a breeze.
Can I add other veggies? Sure, though I’d stick to low-carb options to keep it keto-friendly.
What if I don’t have cream cheese? Sour cream and mayonnaise help with creaminess, but the texture changes a bit without it.
