Some dinners just stick with you—not because they’re fancy, but because they feel like a warm hug after a long day. This beef chicken broccoli casserole is one of those meals. It’s the kind of dish that fills the kitchen with a cozy aroma of garlic and melted cheese, making it impossible to resist the urge to sneak a taste before it’s even out of the oven.
I remember the first time I made this, my mind was elsewhere—half-listening to a podcast and slightly distracted by a phone call that ran longer than expected. Somehow, I got the timing a bit off and nearly forgot to drain the broccoli before mixing everything. Thankfully, the casserole still turned out rich and creamy, with just enough bite from the broccoli to keep things interesting. The golden crust on top was a little more browned than I usually like, but honestly, it added an unexpected crunch that made me want to dig in even faster.
Why You’ll Love It:
- Combines two proteins for a hearty, satisfying meal that feels substantial without being heavy.
- The broccoli adds a fresh pop of color and texture, balancing the creamy cheese sauce nicely.
- It’s simple—and that’s kind of the point. No complicated steps, just good ingredients coming together.
- Feeds a crowd but also reheats well for leftovers, making it a solid choice for busy weeknights.
It’s perfectly fine if you don’t have exactly the same cheeses on hand; the flavor won’t suffer much. Sometimes I swap out mozzarella for a bit of Monterey Jack or even a touch of pepper jack just to mix things up.

Beef, Chicken, and Broccoli Casserole
- Total Time: 1 hour
- Yield: 6
Description
A hearty and comforting casserole combining ground beef, diced chicken, fresh broccoli, and a creamy cheese sauce baked to golden perfection. Perfect for a family dinner.
Ingredients
1 pound ground beef
1 pound boneless, skinless chicken breast, diced into 1/2-inch pieces
4 cups fresh broccoli florets
1 medium onion, finely chopped
3 cloves garlic, minced
2 tablespoons olive oil
1/4 cup all-purpose flour
2 cups whole milk
1 cup chicken broth
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dried thyme
1/2 teaspoon paprika
2 cups shredded sharp cheddar cheese, divided
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 cup cooked white rice
Instructions
Preheat the oven to 375°F (190°C).
Bring a large pot of salted water to a boil. Add the broccoli florets and cook for 2 minutes until bright green and slightly tender. Drain and set aside.
Heat olive oil in a large skillet over medium-high heat. Add the chopped onion and garlic; sauté for 3 minutes until softened.
Add the ground beef to the skillet. Cook, breaking it up with a spoon, until browned and cooked through, about 6-8 minutes. Remove the beef from the skillet and set aside.
In the same skillet, add the diced chicken pieces. Cook for 6-7 minutes until the chicken is cooked through and lightly browned. Remove and set aside with the beef.
Reduce heat to medium and add the flour to the skillet. Stir constantly for 1-2 minutes to cook the flour without browning.
Gradually whisk in the milk and chicken broth, stirring continuously until the sauce thickens, about 4-5 minutes.
Add salt, black pepper, dried thyme, and paprika to the sauce. Stir well.
Remove the skillet from heat and stir in 1 1/2 cups of shredded cheddar cheese until melted and smooth.
In a large mixing bowl, combine the cooked ground beef, cooked chicken, blanched broccoli, cooked rice, and cheese sauce. Mix gently until well combined.
Transfer the mixture to a greased 9×13-inch baking dish.
Sprinkle the top evenly with the remaining 1/2 cup cheddar cheese, shredded mozzarella cheese, and grated Parmesan cheese.
Bake uncovered in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the cheese on top is golden brown.
Remove from the oven and let rest for 5 minutes before serving.

Kitchen Notes: This comes together in one skillet and a single baking dish, so cleanup is pretty manageable. I usually serve it with a simple side salad or some crusty bread to soak up any extra sauce. If you want to mix things up, swapping white rice for quinoa or even cauliflower rice could work—though I haven’t tested those thoroughly myself. For a bit of a twist, stirring in some caramelized onions or a handful of sliced mushrooms before baking adds a lovely depth, but it’s absolutely optional.
FAQ:
Can I make this ahead of time? Yes, prepping it a day ahead and baking it just before dinner works well.
Is this casserole freezer-friendly? Definitely. Freeze leftovers for up to two months and thaw overnight before reheating.
Any tips for cooking the chicken and beef evenly? Cooking them separately helps keep the flavors distinct and ensures both are perfectly done.
Give this casserole a try when you want something that feels like a little celebration after a busy day. It’s comforting, filling, and just the right touch of indulgence.
