How to Make Southern Baked Spaghetti Casserole

  1. Prepare the Oven: Preheat your oven to 350°F (175°C) to ensure even baking of the casserole.

  2. Cook Ground Beef: In a large skillet over medium heat, heat olive oil and add ground beef. Cook until browned, about 4 minutes, breaking it apart with a spoon for an even texture.

  3. Sauté Aromatics: Toss in minced garlic, chopped onion, and diced green pepper. Sauté these together until softened, approximately 4 more minutes, filling your kitchen with a delightful aroma.

  4. Make the Sauce: Drain any excess fat from the skillet, then stir in the diced tomatoes, marinara sauce, fresh basil, oregano, salt, and pepper. Reduce the heat and let it simmer to meld the flavors beautifully.

  5. Cook Spaghetti: In a separate large pot, bring salted water to a boil. Add spaghetti and cook until al dente according to package directions. Drain and set aside, resisting the urge to rinse!

  6. Assemble Casserole: Generously grease a 9×13 inch baking dish. Toss cooked spaghetti with parmesan cheese, then spread it in the dish. Top with the meat sauce, and finish with a sprinkle of mozzarella cheese.

  7. Bake: Place the assembled casserole in the preheated oven and bake uncovered for about 30 minutes. Look for the cheese to melt and turn lightly golden—a sign that it’s ready! Allow it to cool slightly before serving.

Optional: Garnish with fresh basil leaves for an added touch of color and flavor.

Expert Tips for Southern Baked Spaghetti Casserole

  • Cheesy Goodness: Use freshly shredded mozzarella cheese for the best melting experience—store-bought pre-shredded varieties may not melt as well.
  • Perfect Pasta: Cook spaghetti to al dente; this prevents it from becoming mushy once baked in the casserole.
  • Layering Love: When assembling, make sure to evenly distribute the meat sauce. This allows each bite of the Southern Baked Spaghetti Casserole to be flavorful and consistent.
  • Taste Test: Adjust seasonings, especially salt and pepper, to your personal preference before baking—the flavors deepen as it cooks!
  • Avoid Soggy Slices: Let the casserole sit for a few minutes after baking before cutting. This helps the layers hold together better when serving.

What to Serve with Southern Baked Spaghetti Casserole?

As you gather around the table, enjoy these scrumptious pairings that elevate your comforting dish into a delightful feast.

  • Garlic Bread: The warm, buttery crunch of garlic bread perfectly balances the rich, cheesy layers of the casserole and is perfect for soaking up that savory sauce.

  • Fresh Garden Salad: Crisp greens drizzled with a light vinaigrette offer a refreshing contrast to the hearty casserole, enhancing the meal’s overall balance.

  • Roasted Vegetables: Colorful roasted veggies seasoned with herbs bring a delightful crunch and earthy flavors that complement the richness of the spaghetti.

  • Cheesy Breadsticks: Soft, cheesy breadsticks are an indulgent treat that pairs well with the casserole’s savory elements, making every bite even more enjoyable.

  • Sautéed Spinach: Lightly sautéed spinach with garlic provides a burst of freshness and a nutritional boost alongside your dish’s comforting flavors.

  • Red Wine: A glass of medium-bodied red wine, like Chianti or Merlot, enhances the savory notes of the casserole while bringing warmth to the dining experience.

  • Apple Crisp: End your meal on a sweet note with a warm apple crisp, its cinnamon sweetness and crunchy topping beautifully contrasting the savory casserole.

To maintain the quality, be sure to cool the assembled casserole to room temperature before covering.

This time-saving method ensures that you can enjoy hearty, homemade comfort food with minimal effort!

Southern Baked Spaghetti Casserole Recipe FAQs

What type of ground beef should I use for Southern Baked Spaghetti Casserole?
I recommend using lean ground beef (90-93% lean) for a healthier option. If you prefer a lighter dish, ground turkey or chicken also works beautifully and will change the flavor profile slightly while keeping it delicious.

How should I store leftover Southern Baked Spaghetti Casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Just make sure to let it cool completely before sealing to prevent moisture buildup, which could make the casserole soggy.

Can I freeze Southern Baked Spaghetti Casserole?
Absolutely! To freeze, I suggest assembling the casserole without baking it first. Wrap it tightly in plastic wrap and then aluminum foil to ensure it’s airtight. It can be frozen for 2-3 months. When you’re ready to enjoy, thaw it overnight in the fridge, then bake as instructed!

What if my Southern Baked Spaghetti Casserole is too dry?
If it seems a bit dry after baking, it could be that it needed a little more sauce. I recommend stirring in a bit of marinara sauce to the leftover portions when reheating, or you can cover it with foil during baking to retain moisture. Adding a splash of broth can also help.

Are there any dietary considerations for Southern Baked Spaghetti Casserole?
Yes! If you or your guests have dietary allergies, it’s important to check labels on all ingredients, especially pre-made sauces or cheeses. For gluten-free options, simply swap regular pasta for gluten-free pasta, and check that any sauces used are gluten-free.

How can I customize the meat and sauce ratios in this casserole?
For a meat-heavy casserole, I often use around 24 oz. of marinara sauce with a pound of ground beef. However, if you prefer it saucier and less meaty, you can increase the sauce to 32 oz. This flexibility makes it perfect for tailoring the dish to your family’s tastes!
