Step‑by‑Step Instructions for Ground Beef & Spinach Casserole

Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This is a crucial step to ensure your Ground Beef & Spinach Casserole cooks evenly and develops that beautiful golden-brown crust on top. While the oven heats up, take a moment to gather your ingredients and prepare your baking dish by greasing it lightly.

Step 2: Brown the Ground Beef
In a large skillet over medium heat, add the ground beef. Cook, breaking it apart with a spatula, for about 6-8 minutes until it’s fully browned. You’ll know it’s ready when there’s no pink remaining and the meat has a nice, rich color. This step builds a flavorful foundation for your casserole.

Step 3: Sauté Onion and Garlic
Once the beef is browned, stir in the chopped onion and minced garlic. Sauté the mixture for 3-4 minutes, or until the onion becomes translucent and fragrant. This will add depth to your Ground Beef & Spinach Casserole, enhancing its overall flavor profile. Be sure to stir occasionally to prevent burning.

Step 4: Incorporate Spinach and Tomatoes
Next, add the well-drained frozen spinach and diced tomatoes to the skillet. Stir everything together, cooking for about 5 minutes until heated through. The moisture from the tomatoes will blend nicely with the beef and spinach, creating a deliciously savory filling that forms the heart of your casserole.

Step 5: Mix in Cheeses and Seasonings
Lower the heat and gently fold in the ricotta, mozzarella, Parmesan, Italian seasoning, salt, and pepper. Cook for another 5 minutes, stirring continuously until the cheese is melted and the ingredients are evenly combined. The mixture should look creamy and rich—this is what makes the Ground Beef & Spinach Casserole so comforting.

Step 6: Transfer to Baking Dish
Carefully transfer the mixture into your greased 9×13-inch baking dish, spreading it out evenly. This ensures every bite of the casserole is packed with flavor. Once spread, sprinkle a generous layer of breadcrumbs on top to create that delightful, crunchy topping we all love.

Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for 25-30 minutes or until the top is golden brown and bubbling. Keep an eye on it towards the end—when it’s perfectly cooked, it will look irresistible and you’ll smell that comforting aroma filling your kitchen.

Step 8: Cool and Serve
After baking, remove the Ground Beef & Spinach Casserole from the oven and let it cool for about 5 minutes before serving. This allows it to set slightly, making it easier to serve. Dish out portions and enjoy a meal that is sure to delight your family and satisfy those comfort food cravings!
