Key Ingredients
Here’s what makes Ground Beef & Spinach Casserole so delicious—each ingredient plays its part in building those layers of flavor and texture.
- 1 pound ground beef: Provides hearty, savory protein that forms the base of the casserole.
- 1 medium onion, chopped: Adds a sweet, aromatic foundation when softened in the skillet.
- 2 cloves garlic, minced: Infuses fragrant depth and a hint of warmth to the beef mixture.
- 2 cups fresh spinach, roughly chopped: Brings vibrant color and gentle earthiness, wilting perfectly into the sauce.
- 1 can (15 ounces) diced tomatoes, drained: Contributes acidity and juicy bursts without watering down the casserole.
- 1 cup ricotta cheese: Creates a creamy layer that binds the pasta and beef together.
- 1 cup shredded mozzarella cheese: Melts beautifully on top and inside, giving that irresistible gooey stretch.
- 1 cup cooked pasta (such as penne or rotini): Serves as the tender, filling backbone that absorbs all flavors.
- 1 teaspoon Italian seasoning: Blends oregano, basil, and thyme for classic Italian-inspired warmth.
- 1/2 teaspoon salt: Enhances and balances all the flavors in the dish.
- 1/4 teaspoon black pepper: Adds a subtle kick and depth to every bite.
- 1/2 cup grated Parmesan cheese: Sprinkles on a nutty, savory finish that browns gorgeously under the broiler.
- 1 tablespoon olive oil: Used for sautéing onions and garlic without sticking, adding a fruity richness.
How To Make Ground Beef & Spinach Casserole
This casserole comes together in two simple stages: building a flavorful beef and spinach mixture on the stovetop, then layering it with pasta and cheeses before a golden bake. You’ll start by sautéing aromatics, browning your beef, and wilting fresh spinach. Next, you’ll combine everything with creamy ricotta and mozzarella in a bowl, transfer to a baking dish, and finish under the broiler for that perfect golden crust. Follow these steps, paying special attention to techniques like draining excess fat and folding gently to keep your casserole rich without becoming greasy.
1. Preheat your oven to 350°F (175°C). Make sure it’s fully heated so the casserole bakes evenly.
2. In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook until softened, about 4–5 minutes, stirring occasionally.
3. Add the minced garlic to the skillet and sauté for another minute until fragrant—watch closely so it doesn’t burn.
4. Increase the heat to medium-high, then add the ground beef. Cook until browned, breaking it apart with a spoon, about 6–8 minutes. Drain any excess fat from the pan.
5. Stir in the diced tomatoes, chopped spinach, Italian seasoning, salt, and black pepper. Cook for 2–3 minutes until the spinach is wilted and the mixture is heated through.
6. In a large bowl, combine the cooked pasta, ricotta cheese, and half of the mozzarella cheese. Mix well to ensure every noodle is coated in creamy goodness.
7. Pour the ground beef and spinach mixture over the pasta and cheese mixture, then fold gently to combine all ingredients uniformly.
8. Transfer the combined mixture into a greased 9×13-inch baking dish, spreading it into an even layer.
9. Top the casserole with the remaining mozzarella cheese and sprinkle the grated Parmesan cheese evenly on top.
10. Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes.
11. Remove the foil and bake for an additional 10–15 minutes, or until the cheese is bubbly and golden brown.
12. Let the casserole cool for about 5 minutes before serving to help it set and make slicing easier.

Frequently Asked Questions
Here are answers to common questions that come up when making this casserole.
- How long does it take to prepare and bake this casserole?
It takes about 20 minutes to prepare the ingredients, including chopping vegetables and cooking the beef mixture, and about 35 to 40 minutes to bake (25 minutes covered and 10 to 15 minutes uncovered) for a total time of roughly 55 to 60 minutes.
- Can I substitute frozen spinach for fresh, and if so, what adjustments should I make?
You can substitute one 10-ounce package of frozen spinach, but be sure to thaw and thoroughly squeeze out excess moisture before adding it to the skillet to prevent a watery casserole. The cooking time for the beef and tomatoes remains the same.
- How can I prevent the casserole from becoming too watery?
To avoid excess moisture, drain the diced tomatoes well before adding them, drain any fat after browning the ground beef, and squeeze out water from any substitutions like frozen spinach. Stir ingredients gently to allow excess liquid to evaporate during the initial stovetop step.
- Is it possible to prepare this casserole ahead of time, and how should I store it?
Yes, you can assemble the casserole up to 24 hours in advance. Cover the baking dish tightly with plastic wrap or foil and refrigerate. Before baking, let it sit at room temperature for about 15 minutes, then bake following the recipe’s instructions, adding an extra 5 to 10 minutes to the covered baking time if it’s very cold.
- What are some low-carb or gluten-free variations for this recipe?
To make it low carb, substitute the cooked pasta with cauliflower rice or zucchini noodles, and reduce or omit the ricotta cheese if desired. For a gluten-free version, ensure the pasta is gluten-free and check that any added seasonings or canned tomatoes are certified gluten-free.
- How should I store and reheat leftovers to maintain the best texture?
Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, cover the casserole with foil and warm in a 350°F oven for 15–20 minutes or microwave individual portions until heated through. Removing the foil in the last few minutes helps crisp the cheese topping.
