- 1 pound 90 to 92% lean ground beef: Offers protein while minimizing fat content.
- ½ cup diced white or yellow onion: Adds sweetness and depth to the flavor.
- 1 teaspoon minced garlic: Elevates the overall taste profile.
- 2 teaspoons Italian seasoning: Brings aromatic herbs together for a savory experience.
- ½ teaspoon salt (or to taste): Enhances all flavors in the dish.
- ½ teaspoon freshly ground black pepper: Adds a hint of spice.
- 24 ounces marinara sauce (your favorite brand): Provides moisture and flavor.
- 15 ounce can diced tomatoes (don’t drain): Introduces texture and freshness.
- ¼ cup chopped fresh Italian parsley: A finishing touch for color and brightness.
- 1 tablespoon olive oil: Used for sautéing veggies and browning meat.
- 1 egg (lightly beaten): Acts as a binder for the casserole ingredients.
- ¾ cup finely shredded Parmesan cheese (divided): Two-layered cheesy goodness.
- 1 cup part-skim ricotta cheese: Creamy and flavorful addition.
- 2 cups shredded part-skim mozzarella cheese (about 8 ounces divided): Melts beautifully into the dish.
Step-by-Step Directions
- Preheat the Oven
- Preheat the oven to 350 degrees F. This ensures the casserole will bake evenly once it’s assembled.
- Prepare the Pasta
- Cook the spaghetti noodles according to package instructions until al dente. Drain and set aside.
- Cook the Meat and Vegetables
- In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic; sauté until soft and fragrant, about 3-5 minutes. Add the ground beef, breaking it apart, and cook until browned, about 7-10 minutes.
- Season the Meat
- Once the meat is browned, stir in the Italian seasoning, salt, and black pepper. Mix well before adding the marinara sauce and diced tomatoes. Let it simmer for 5 minutes to blend the flavors.
- Combine Noodles and Meats
- In a large bowl, combine the cooked spaghetti noodles with the meat sauce mixture. Stir in the chopped parsley and one half of the Parmesan cheese.
- Assemble the Casserole
- Coat a 13- x 9-inch baking dish with nonstick cooking spray. Spoon half of the spaghetti mixture into the dish, spreading it evenly. Add whisked egg and ricotta cheese in dollops on top. Layer with the remaining spaghetti.
- Add Cheese Topping
- Sprinkle the remaining mozzarella and Parmesan cheeses over the top of the casserole. This will create a beautiful, melty crust as it bakes.
- Bake
- Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and continue to bake for an additional 15-20 minutes, or until the cheese is golden and bubbly.
Common Mistakes to Avoid & Pro Tips
- Mistake: Overcooking the Pasta
- Fix: Cook spaghetti until al dente; it will soften further in the oven.
- Mistake: Not allowing the casserole to cool
- Fix: Let the casserole sit for 10 minutes after baking for easier slicing.
- Mistake: Using low-quality sauce
- Fix: Choose a marinara sauce you genuinely enjoy, as it will greatly impact the flavor.
Pro Tips:
- Prepare the meat sauce a day ahead for convenience.
- Feel free to swap ground beef for turkey or chicken for a lighter option.
