Ingredients
- 12 ounces spaghetti noodles
- 1 pound ground beef (ensure it’s from a trusted source)
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 1 (24-ounce) jar marinara or spaghetti sauce (choose your favorite brand or homemade)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon crushed red pepper flakes (optional, for a subtle kick)
- Salt and freshly ground black pepper, to taste
- 2 cups shredded mozzarella cheese
- 1 cup grated Parmesan cheese
- 2 large eggs
- 1 cup ricotta cheese
- 2 tablespoons olive oil
- Fresh parsley or basil, chopped (for garnish)
How To Make Spaghetti Casserole
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil. Add the spaghetti noodles and cook according to package instructions until al dente. Drain the noodles and drizzle with a little olive oil to prevent sticking. Set aside.
Step 2: Prepare the Meat Sauce
Heat olive oil in a large skillet over medium heat. Add the chopped onion and sauté for about 3-4 minutes until translucent. Stir in the minced garlic and cook for another 30 seconds until fragrant. Add the ground beef and cook until browned, breaking it apart with a wooden spoon as it cooks. Drain any excess fat.
Step 3: Season the Sauce
Pour the marinara sauce into the skillet with the beef. Stir in dried oregano, basil, crushed red pepper flakes (if using), salt, and pepper. Let the sauce simmer gently for 10 minutes, allowing the flavors to meld.
Step 4: Prepare the Cheese Mixture
In a medium bowl, whisk together the eggs, ricotta cheese, and half of the grated Parmesan cheese. This mixture will add creaminess and help bind the casserole together.
Step 5: Assemble the Casserole
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the cooked spaghetti noodles with the meat sauce. Fold in the ricotta cheese mixture until evenly distributed.
Transfer half of the spaghetti mixture to a greased 9×13-inch baking dish. Sprinkle 1 cup of shredded mozzarella cheese over the layer. Add the remaining spaghetti mixture on top, then finish with the remaining mozzarella and Parmesan cheese.
Step 6: Bake
Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
Step 7: Garnish and Serve
Allow the casserole to cool for about 5 minutes before serving. Garnish with freshly chopped parsley or basil for a pop of color and fresh flavor.
Expert Tips
- Use day-old spaghetti or chill freshly cooked noodles to prevent the casserole from becoming mushy.
- For extra flavor, sauté the onions and garlic in a bit of butter alongside the olive oil.
- Don’t skip the eggs in the cheese mixture—they help hold the casserole together beautifully.
- If you want a crispier top, broil the casserole for 2-3 minutes at the end of baking, but watch closely to avoid burning.
- Make sure to drain the ground beef well to keep the casserole from becoming greasy.
- Feel free to use part-skim mozzarella for a lighter version without sacrificing meltiness.
Variations and Customizations
- Vegetarian version: Substitute the ground beef with sautéed mushrooms, zucchini, and bell peppers for a hearty veggie-packed casserole.
- Spicy twist: Add chopped jalapeños or increase the crushed red pepper flakes for a bolder heat.
- Cheese lovers: Mix in provolone or fontina cheese along with mozzarella for more complex flavors.
- Herb infusion: Use fresh herbs like thyme, rosemary, or oregano instead of dried for a fragrant, garden-fresh taste.
- Gluten-free: Swap out regular spaghetti for your favorite gluten-free pasta to accommodate dietary needs.
- Make it meaty: Add cooked sausage or ground lamb for a richer flavor profile.
How to Store Leftovers
After enjoying your spaghetti casserole, you’ll likely have leftovers to savor later. Allow the casserole to cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3-4 days. To reheat, place individual portions in the microwave or warm the entire dish in a 350°F (175°C) oven, covered with foil, until heated through (about 15-20 minutes). For longer storage, you can freeze the casserole for up to 3 months. Be sure to thaw it overnight in the refrigerator before reheating to maintain the best texture and flavor.
FAQ
Can I make this spaghetti casserole ahead of time?
Absolutely! You can assemble the casserole a day in advance, cover it, and refrigerate until ready to bake. Just add a few extra minutes to the baking time if baking straight from the fridge.
What type of cheese works best in this casserole?
Mozzarella and Parmesan are classic choices because mozzarella melts beautifully and Parmesan adds a sharp, salty flavor. Ricotta adds creaminess and helps bind the casserole. Feel free to experiment with other melting cheeses like provolone or fontina if you prefer.
Can I use a different type of pasta?
Yes! While spaghetti is traditional here, you can use penne, rigatoni, or any pasta shape you have on hand. Just adjust the cooking time slightly based on the pasta type.
Is this recipe suitable for picky eaters?
Definitely! This casserole is mild in flavors and familiar in taste, making it ideal for picky eaters. You can always reduce or omit the red pepper flakes and finely chop vegetables to sneak in extra nutrition without changing the overall flavor.
