How to Make Ground Beef Broccoli Casserole

With two leading players, beef and broccoli, this simple casserole delivers mouthwatering flavors. The seasonings jazz up beef and broccoli and bake together with three different cheeses for the ultimate comfort food.

Ingredients You Need

• Broccoli: Adds a pop of color, nutrition, and flavor. You’ll need trimmed and cut broccoli florets for this recipe. Use fresh or frozen.
• Ground beef: The primary protein source, making this casserole dish hearty and savory. It also adds a satisfying texture that complements the smooth texture of broccoli and cheeses. Go for an 80/20 lean ground beef blend for the best balance of meaty and juicy. 
• Italian seasoning: A blend of various herbs like oregano, basil, thyme, and rosemary infuses the ground beef with rich and aromatic flavors.
• Garlic powder: Adds a mild garlic taste without the overpowering flavor of fresh garlic.
• Salt and black pepper: Enhances the overall flavor of the dish.
• Parmesan cheese:  Adds a nutty, salty, and savory flavor to the casserole and contributes to the creamy texture when melted.
• Cream cheese: Adds luscious richness to the bake and helps bind all the ingredients together.
• Mozzarella cheese: Offers gooey, stretchy, and melty goodness. It’s used in the casserole and on top to create a golden-brown crust.

Ingredient Substitutions

Even though this is such a simple recipe, you might need one of the key ingredients. Review the recommendations here for quick and clever substitutions for your homemade ground beef and broccoli casserole.

Here are suggested substitutions:

• Not a fan of broccoli? Substitute it with cauliflower florets for a similar texture.
• Use another ground meat. Swap out the ground beef with ground turkey, chicken, or pork if you prefer a different protein source. You can even opt for Italian sausage instead.
• Add more aromatics. Bump the flavors by mixing finely chopped yellow or green onions and minced fresh ginger.
• Use seasonings. While this recipe calls for Italian seasoning, feel free to use what you have on hand. Ranch seasoning would be absolutely delicious here, too.
• Try different cheeses. While I wouldn’t recommend swapping out the cream cheese unless necessary (it won’t be as creamy), you can sprinkle in other cheeses like Swiss, Colby, or cheddar cheese instead of Parmesan and mozzarella.

Step-By-Step Instructions

This ground beef and broccoli casserole comes together in 30 minutes. You can cut down on time even more if the broccoli is already trimmed and cut into florets.

Follow these simple directions, and you can’t go wrong!

1. Preheat the oven to 375 F.
2. Bring water to a boil in a medium saucepan and steam the broccoli for five to seven minutes, until bright green and tender.
3. Meanwhile, cook the ground beef in a skillet over medium-high heat in an even layer, breaking it up with a wooden spoon or spatula. Season with Italian seasoning, garlic powder, salt and pepper.
4. Remove the meat from heat and mix in the broccoli, Parmesan cheese, and cream cheese. Stir thoroughly until well combined. Fold in one cup of shredded mozzarella.
5. Transfer to an 8×8-inch baking dish and top with remaining cheese. Bake for 15 minutes until the cheese bubbles and turns golden brown on top.
6. Allow the broccoli casserole to rest for at least five minutes before garnishing with optional chili pepper flakes. Serve warm.

How to Store This Recipe

Leftover ground beef and broccoli casserole can be stored in an airtight container in the refrigerator for up to four days. Transfer a single serving into a small saucepan to reheat leftovers and add a splash of water or broth. Reheat over medium heat until warmed through.

Alternatively, you can reheat the entire casserole, covered with foil to trap heat and avoid burning the top, in a preheated oven for a few minutes.

Can I Make Ground Beef and Broccoli Casserole Ahead of Time?

Yes! You can prep the casserole, but don’t bake it and store it in the refrigerator covered for up to three days. Then, when ready to bake, remove it from the refrigerator and allow it to come to room temperature first. Then bake and serve immediately.

Can I Freeze Ground Beef and Broccoli Casserole?

Yes, you can freeze this casserole, but because of the dairy, the texture may change after freezing and thawing. To freeze, transfer the casserole to a freezer-safe container and freeze for up to two months. When ready to enjoy again, thaw overnight in the fridge and reheat in the oven until warmed through.
