Step-by-Step Instructions
Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 Ă— 9-inch baking dish with cooking spray or a little olive oil.
Cook the Ground Beef
Place a large skillet over medium heat.
Add the ground beef and cook, breaking it apart with a spatula as it browns.
Continue cooking until the beef is completely cooked and nicely browned.
Drain any excess grease if necessary.
Add the Tomatoes and Seasoning
Add the well-drained diced tomatoes to the cooked beef.
Sprinkle in the Italian seasoning and season with salt and black pepper to taste.
Stir everything together and cook for another 2–3 minutes so the flavors can combine.
Assemble the Casserole
Transfer the beef and tomato mixture to the prepared baking dish.
Spread it evenly across the dish.
Sprinkle the shredded mozzarella evenly over the entire surface.
Bake
Place the baking dish in the preheated oven.
Bake for 15–20 minutes, or until the mozzarella is completely melted, bubbly, and lightly golden.
For a deeper golden crust, switch the oven to broil for the final 1–2 minutes, watching carefully so the cheese doesn’t burn.
Finish and Serve
Remove the casserole from the oven and allow it to rest for about 5 minutes.
Sprinkle the fresh chopped parsley over the top.
Serve warm with your favorite side dishes.
Best Tips
Drain the tomatoes well: Excess liquid can make the casserole watery.
Shred your own mozzarella: Freshly shredded mozzarella generally melts more smoothly than many pre-shredded varieties.
Brown the beef properly: Allowing the beef to develop some golden-brown color adds extra flavor.
Don’t overcrowd the skillet: If you’re doubling the recipe, brown the beef in batches for better browning.
Let it rest: A few minutes of resting helps the casserole settle and makes serving easier.
Best Ingredient Alternatives
Ground turkey: Substitute ground turkey for the beef for a lighter variation.
Italian sausage: Mild Italian sausage adds extra seasoning and a richer flavor.
Cheddar cheese: Replace some or all of the mozzarella with shredded cheddar.
Provolone: Provolone creates a deliciously rich, melty topping.
Fresh tomatoes: Fresh tomatoes can be used, but remove some of their excess liquid before adding them.
Recipe Variations
Cheesy Beef and Bell Pepper Bake
Add diced red, yellow, or green bell peppers to the skillet while browning the beef.
Spicy Beef Bake
Add diced jalapeños, red pepper flakes, or your favorite hot sauce for extra heat.
Beef and Onion Casserole
Sauté a finely chopped onion with the ground beef for a deeper savory flavor.
Mushroom Beef Bake
Add sliced mushrooms and cook them with the beef before adding the tomatoes.
Extra-Cheesy Version
Mix mozzarella with a little grated Parmesan before sprinkling it over the casserole.
What to Serve With
Serve this cheesy beef bake with a crisp green salad for a fresh contrast.
Roasted broccoli, asparagus, zucchini, or green beans also make excellent sides.
For a heartier meal, serve it with garlic bread, roasted potatoes, rice, or your favorite pasta.
Make-Ahead Instructions
You can prepare the ground beef and tomato mixture up to 24 hours ahead of time.
You can also assemble the entire casserole, cover it tightly, and refrigerate it before baking.
When ready to cook, place it in the preheated oven and add a few extra minutes to the cooking time if the casserole is still very cold.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 4 days.
For the best texture, only reheat the amount you plan to eat.
Reheating
Microwave: Place an individual portion on a microwave-safe plate and heat for 1–2 minutes, or until hot throughout.
Oven: Place the casserole in a 350°F (175°C) oven and heat until warmed through.
Covering the dish loosely with aluminum foil can help prevent the cheese from becoming overly browned.
Freezing
This casserole can be frozen before or after baking.
For an unbaked casserole, assemble the beef mixture and cheese in a freezer-safe baking dish.
Cover tightly with aluminum foil and freeze for up to 3 months.
Thaw overnight in the refrigerator before baking.
Common Mistakes to Avoid
Forgetting to drain the tomatoes: Excess liquid can create a soggy base.
Using too much liquid: Keep the tomato mixture relatively thick before adding it to the baking dish.
Overcooking the mozzarella: Too much oven time can make the cheese dry or rubbery.
Skipping the resting time: Allowing the casserole to rest for a few minutes makes it easier to serve.
Not browning the beef: Proper browning gives the meat a deeper, richer flavor.
