- 1 jar (24 oz.) of marinara or pasta sauce (homemade or store-bought)
- 1 can (14.5 oz.) diced tomatoes (optional for extra texture)
- 1 teaspoon Italian seasoning
- 1 teaspoon paprika (optional for a smoky kick)
- 1 teaspoon sugar (balances the acidity of tomatoes)
- Salt and pepper to taste

Substitutions and Variations
One of the great things about Southern baked spaghetti casserole is its versatility. Here are a few substitutions and variations you can try, depending on your preferences or dietary needs:
- Meat Substitutes: Instead of ground beef, you can use Italian sausage, ground turkey, or even ground chicken. For a vegetarian option, you can substitute the meat with sautéed mushrooms, zucchini, or eggplant.
- Cheese Variations: While mozzarella and Parmesan are classic choices, feel free to experiment with other cheeses like cheddar, provolone, or gouda for added richness.
- Sauce Choices: A traditional marinara sauce works great, but you can add a twist by using a vodka sauce or even an Alfredo sauce for a creamier casserole.
- Gluten-Free: You can use gluten-free pasta to make this dish gluten-free without sacrificing any flavor.
- Vegetable Additions: Add some nutrition by incorporating veggies like spinach, bell peppers, or chopped carrots into your sauce.
- Low-Carb: Swap out the pasta with spaghetti squash or zucchini noodles for a low-carb version of this recipe.
Step-by-Step Cooking Instructions

Now that we have our ingredients and variations covered, it’s time to start cooking. Here’s a step-by-step guide to making your Southern baked spaghetti casserole.
1. Cook the Spaghetti
- Begin by bringing a large pot of salted water to a boil. Cook the spaghetti according to the package instructions until al dente. Be sure not to overcook the pasta since it will continue cooking in the oven.
- Once cooked, drain the spaghetti and set it aside.
2. Prepare the Meat Sauce
- In a large skillet, heat some oil over medium heat. Add the ground beef (or Italian sausage) and cook until browned, breaking it up with a spoon as it cooks. Drain excess fat if necessary.
- Add the chopped onions and minced garlic, cooking until the onions are translucent.
- Stir in the marinara sauce, diced tomatoes (if using), Italian seasoning, paprika, sugar, salt, and pepper. Let the sauce simmer on low for 10-15 minutes, allowing the flavors to meld together.
3. Mix the Cheeses
- In a medium bowl, combine the ricotta (or cottage cheese), sour cream, eggs, half of the shredded mozzarella, and half of the Parmesan. Mix until smooth.
4. Assemble the Casserole
- Preheat your oven to 350°F (175°C).
- Grease a 9x13-inch baking dish with butter or non-stick spray.
- Spread a thin layer of the meat sauce at the bottom of the baking dish.
- Add half of the cooked spaghetti, then spoon half of the cheese mixture over the pasta.
- Pour more meat sauce over the cheese layer, and repeat with the remaining pasta and cheese.
- Finish with a final layer of meat sauce.
5. Top the Casserole
- Sprinkle the remaining mozzarella, Parmesan, and shredded cheddar over the top of the casserole. The cheddar adds a nice Southern twist with its bold flavor.
6. Bake the Casserole
- Cover the dish with foil and bake in the preheated oven for 25 minutes.
- Remove the foil and bake for another 10-15 minutes, or until the cheese on top is golden and bubbly.
7. Let it Rest
- Allow the casserole to rest for about 10 minutes before serving. This helps the layers set and makes it easier to slice and serve.
Common Mistakes to Avoid
Even a simple casserole can come with some potential pitfalls. To ensure your baked spaghetti casserole turns out perfectly, avoid these common mistakes:
- Overcooking the Pasta: Al dente pasta is key since it will continue cooking in the oven. Overcooking can lead to mushy spaghetti.
- Too Watery Sauce: If your sauce is too thin, your casserole might not hold together well. Let the sauce simmer to thicken before adding it to the casserole.
- Skipping the Resting Period: After baking, it’s essential to let the casserole rest for a few minutes. This helps the cheese set and makes the dish easier to serve.
- Using Too Little Cheese: Be generous with your cheese! This is a comforting dish, and the cheese adds richness and flavor. Don’t skimp on the mozzarella, Parmesan, or cheddar.
