How to Make Ground Beef & Spinach Casserole

1. Preheat the oven to 375 °F (190 °C). This step ensures your casserole bakes evenly and gets that golden-brown topping we all desire!

2. Brown the ground beef in a large skillet over medium heat, breaking it apart with a spatula. Cook until it s no longer pink, about 5-7 minutes.

3. Sauté the chopped onion and minced garlic in the same skillet for 3-4 minutes until softened and fragrant, adding depth to your dish.

4. Combine the ingredients by stirring in the frozen spinach, diced tomatoes, ricotta, mozzarella, Parmesan, Italian seasoning, salt, and pepper. Heat through for 5 minutes until everything is warmed and blended.

5. Transfer the flavorful mixture to a greased 9×13-inch baking dish, spreading it evenly. Sprinkle breadcrumbs generously on top for that irresistible crunchy finish.

6. Bake for 25-30 minutes, or until the top is beautifully golden brown and bubbly. This is where the magic happens!

Optional: Garnish with fresh herbs like basil or parsley for a pop of color and added flavor.

Ground Beef & Spinach Casserole Recipe FAQs

What type of ground beef should I use?
Absolutely! For this Ground Beef & Spinach Casserole, I recommend using lean ground beef which provides the savory flavor while reducing excess grease. If you prefer a lighter alternative, ground turkey or chicken works just as well, giving you a similar texture with fewer calories.

How do I store leftovers properly?
Very! After enjoying your meal, let the casserole cool completely. Transfer into an airtight container and store in the refrigerator for up to 5 days. When you re ready to dig in again, simply reheat in the microwave or bake until warmed through, which will enhance the flavors even more!

Can I freeze the casserole?
Certainly! To freeze your Ground Beef & Spinach Casserole, allow it to cool completely first. Cut it into individual portions and transfer them into airtight containers or resealable freezer bags. It can be frozen for up to 3 months. When you want to enjoy a slice, simply thaw overnight in the refrigerator before reheating for the best results!

What should I do if the casserole is dry?
Don t worry; it happens sometimes! If your casserole comes out dry, next time you can either add a touch more ricotta or a splash of chicken or vegetable broth before baking. If you ve already baked it, consider serving with a dollop of marinara sauce or sour cream on top to add moisture and extra flavor.

Are there any dietary considerations I should keep in mind?
Absolutely! If you re cooking for someone with allergies, be cautious with the cheeses. Ricotta and mozzarella can be replaced with dairy-free alternatives to make this casserole vegan. Additionally, always check ingredient labels for any hidden allergens, and feel free to customize the recipe with your favorite vegetables to suit dietary needs.

Can I use fresh spinach instead of frozen?
Of course! If you prefer fresh spinach, chop enough to make about 2-3 cups, then sauté it for about 2-3 minutes alongside the onion and garlic. This will ensure it wilts down nicely and integrates perfectly into the casserole without extending your cooking time. Enjoy experimenting with flavors!
