Substitutions and Variations
The beauty of a casserole is its versatility, and Southern Baked Spaghetti Casserole is no exception. You can easily adjust the ingredients to suit your taste preferences or dietary needs. Here are some ideas:

- Pasta alternatives: If you want to make this dish gluten-free, simply swap out regular spaghetti for your favorite gluten-free pasta. You can also use whole wheat or chickpea pasta for added fiber.

Step-by-Step Cooking Instructions
Ready to dive into making this delicious Southern Baked Spaghetti Casserole? Follow these step-by-step instructions to create a casserole that will have everyone coming back for seconds.

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch casserole dish with non-stick spray or oil.
Step 2: Cook the Spaghetti
Bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until al dente. Drain the pasta and set it aside.
Step 3: Cook the Meat and Vegetables
In a large skillet, heat the olive oil over medium heat. Add the ground beef or sausage, breaking it apart with a spatula. Cook until browned, about 5-7 minutes. Once the meat is mostly cooked through, add the finely chopped onion and minced garlic. Sauté until the onions are soft and translucent, about 3-4 minutes.
Step 4: Prepare the Sauce
To the meat mixture, add the marinara sauce, diced tomatoes, Italian seasoning, and red pepper flakes if you're using them. Stir everything together and let the sauce simmer for 10 minutes. Taste and season with salt and black pepper as needed.
Step 5: Mix the Pasta and Sauce
In a large bowl, combine the cooked spaghetti with the meat sauce. Stir in the sour cream or cream cheese until everything is well combined. This adds an extra layer of creaminess that makes the casserole irresistible.
Step 6: Assemble the Casserole
Spread half of the spaghetti mixture into the prepared casserole dish. Sprinkle 1 cup of mozzarella and ½ cup of cheddar cheese evenly over the top. Add the remaining spaghetti mixture on top, then sprinkle the rest of the mozzarella, cheddar, and Parmesan cheese.
Step 7: Bake
Cover the casserole dish with aluminum foil and bake in the preheated oven for 25 minutes. After 25 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly with golden edges.
Step 8: Garnish and Serve
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. Garnish with fresh parsley or basil, and enjoy!
Common Mistakes to Avoid
When making Southern Baked Spaghetti Casserole, there are a few common mistakes that you can avoid to ensure your dish turns out perfectly:
- Overcooking the pasta: Be sure to cook the spaghetti al dente (firm to the bite), as it will continue to cook while baking. Overcooked pasta can become mushy after baking.
- Using too much sauce: While it's tempting to add extra sauce, too much can make the casserole watery. Stick to the recipe measurements to ensure the casserole holds together.
- Skipping the resting time: Let the casserole sit for a few minutes before serving. This helps the dish set and makes it easier to slice and serve.
- Not seasoning properly: Taste your sauce before assembling the casserole and adjust the seasoning. A bland sauce can affect the overall flavor of the dish.
Serving and Presentation Tips
Southern Baked Spaghetti Casserole is a hearty dish, so it’s best served with lighter side dishes to balance out the meal. Here are some ideas for what to serve alongside your casserole:
- A simple green salad with a tangy vinaigrette
- Garlic bread or buttery dinner rolls
- Steamed vegetables such as broccoli, green beans, or asparagus
- Roasted vegetables like zucchini, carrots, or bell peppers
How to Serve Southern Baked Spaghetti Casserole
For a family-style meal, you can simply slice the casserole into squares and serve it directly from the baking dish. If you're hosting a more formal gathering, try serving individual portions with a garnish of fresh herbs and a drizzle of olive oil or balsamic glaze for added flair.
Presentation Ideas for Southern Baked Spaghetti Casserole
Make your Southern Baked Spaghetti Casserole look as good as it tastes with these presentation tips:

- Layer the cheese: Add extra cheese on top in the final few minutes of baking for a golden, bubbly presentation.
- Slice into squares: For a neater presentation, let the casserole cool slightly before cutting it into squares for serving.
