Step-by-Step Instructions to Make Southern Spaghetti Bake

This casserole comes together in a few simple stages: preparing the components, assembling the layers, and baking to perfection. Follow these steps for a flawless result.

1. Prepare the Pasta and Meat Sauce

First, preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. Cook the spaghetti according to package directions until it’s al dente. While the pasta cooks, start your meat sauce. In a large skillet, brown the ground beef with the chopped onion over medium-high heat. Once cooked, drain any excess fat. Stir in the minced garlic and cook for another minute until fragrant. Finally, add the marinara sauce, diced tomatoes, and Italian seasoning. Let the sauce simmer for about 10 minutes to allow the flavors to meld.

2. Mix the Creamy Cheese Filling

In a large bowl, combine the softened cream cheese, sour cream, cottage cheese, beaten egg, and grated Parmesan cheese. Mix until everything is well combined and the mixture is smooth and creamy. This will form the luscious middle layer of your Southern Spaghetti Bake.

3. Assemble and Bake the Casserole

Now for the fun part! Spread half of the cooked spaghetti into the bottom of your prepared baking dish. Top it with the entire cream cheese mixture, spreading it into an even layer. Add the remaining spaghetti on top of the cheese layer. Pour the hearty meat sauce over everything, ensuring it covers the spaghetti completely. Finally, sprinkle the shredded mozzarella cheese evenly over the top. Bake for 25-30 minutes, or until the cheese is melted, bubbly, and beautifully golden brown on top.

Pro Tips for a Perfect Bake Every Time

  • Don’t Overcook the Pasta: Cook the spaghetti just until al dente. It will continue to cook in the oven, and this prevents it from becoming mushy.
  • Soften the Cream Cheese: Make sure your cream cheese is at room temperature. This makes it much easier to mix into a smooth, lump-free filling.
  • Let it Rest: After taking the casserole out of the oven, let it rest for 10-15 minutes before slicing. This allows it to set up, making it much easier to serve clean portions.

Fun Variations to Try

While this classic Southern Spaghetti Bake is fantastic as is, feel free to get creative! Here are a few ideas:

  • Different Meats: Swap the ground beef for Italian sausage, ground turkey, or even a meatless crumble. For a similar comforting dish with a different twist, check out this classic baked spaghetti casserole (coming soon).
  • Spice it Up: Add a pinch of red pepper flakes to the meat sauce for a little kick of heat.
  • Add Veggies: Sautéed mushrooms, bell peppers, or spinach can be added to the meat sauce for extra flavor and nutrition.

What to Serve with Your Spaghetti Bake

This hearty casserole is a meal in itself, but it pairs wonderfully with a few simple sides. A crisp green salad with a vinaigrette dressing, some steamed green beans, or a side of warm garlic knots are all excellent choices to round out your dinner.

Frequently Asked Questions

Absolutely! You can assemble the entire casserole up to 24 hours in advance. Cover it tightly and store it in the refrigerator. When you’re ready to eat, you may need to add about 10-15 minutes to the baking time since it’s starting from cold.

The key is the creamy cheese filling in this recipe, which adds a significant amount of moisture. Also, ensure you have enough sauce to generously cover the pasta. Letting the casserole rest for 10-15 minutes after baking also helps the moisture settle back into the dish.

The ‘Southern’ touch comes from the ultra-creamy cheese layer, typically made with cream cheese, sour cream, and sometimes cottage cheese. This creates a richer, tangier filling than what’s found in a standard baked spaghetti.

While they share similar flavors, the main difference is the pasta. Baked spaghetti uses spaghetti noodles, which are typically mixed with the sauce and cheese layers, whereas lasagna uses wide, flat lasagna noodles to create distinct, separate layers.
