Let’s break down the essentials that make this casserole so comforting and flavorful:
Transforming simple ingredients into this layered masterpiece is easier than you think. You’ll brown, wilt, mix, and bake to create a dish that’s creamy on the inside with a perfectly golden cheese crust. Follow these steps closely to ensure every layer cooks evenly and the flavors meld beautifully.
1. Preheat your oven to 350°F (175°C) to ensure it’s hot and ready when the casserole goes in.
2. In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook, stirring occasionally, until softened and translucent, about 4–5 minutes.
3. Add the minced garlic to the skillet and sauté for another minute until fragrant, taking care not to let it brown too much.
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 before proceeding.
5. Stir in the drained diced tomatoes, roughly chopped spinach, Italian seasoning, salt, and black pepper. Cook for 2–3 minutes until the spinach wilts and the flavors meld.
6. In a large mixing bowl, combine the cooked pasta, ricotta cheese, and half of the shredded mozzarella cheese. Mix well so every piece of pasta is coated in creamy ricotta.
7. Pour the ground beef and spinach mixture over the pasta and cheese. Fold gently with a spatula to combine everything evenly without crushing the pasta.
8. Transfer the combined mixture into a greased 9×13-inch baking dish, spreading it out into an even layer.
9. Top the casserole with the remaining mozzarella cheese and generously sprinkle the grated Parmesan cheese on top.
10. Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. This traps steam and melts the cheeses inside.
11. Remove the foil and bake for an additional 10–15 minutes, or until the cheese is bubbly and golden brown. Let the casserole rest for about 5 minutes before serving to help it set.

Got questions about timing, make-ahead tricks, or ingredient swaps? Here are the answers to the most common queries so your casserole comes out perfect every time.
The total time is about 50–55 minutes. Prep—chopping, browning the beef, and mixing ingredients—takes roughly 15–18 minutes. Baking covered and then uncovered in a preheated 350°F oven requires 35–40 minutes, plus a brief 5-minute rest before serving.
Yes. You can mix and layer all ingredients in the greased baking dish, cover it tightly with foil, and refrigerate for up to 24 hours. When ready to bake, remove from the fridge, uncover, and bake for 25 minutes covered, then 10–15 minutes uncovered, adding a few extra minutes if it’s cold.
Make sure to drain the diced tomatoes thoroughly and squeeze excess moisture from any thawed frozen spinach. Cook pasta al dente so it doesn’t release too much starch. After baking covered, remove the foil to allow steam to escape and the cheese to crisp, and let the dish rest for 5 minutes before serving to set.
You can swap ground beef for ground turkey or chicken, use frozen spinach (thawed and well-drained), or replace ricotta with cottage cheese. Whole wheat, gluten-free, or alternative pasta shapes all work. Feel free to add diced bell peppers or zucchini when sautéing the onions and garlic for extra veggies.
Transfer cooled leftovers to an airtight container and refrigerate for up to 3 days. To reheat, microwave individual portions until hot throughout or bake in a 350°F oven for 10–12 minutes, covered with foil to prevent drying, then uncover for a minute to regain the cheese’s stretchiness.
Yes. Assemble the casserole but don’t bake, then cover tightly with foil and plastic wrap and freeze for up to 2 months. Thaw overnight in the refrigerator, remove plastic wrap, and bake at 350°F for about 30 minutes covered, then 10–15 minutes uncovered until bubbly and golden.
