Ingredient Breakdown

• 12 oz spaghetti: The pasta base for this dish. Use any long pasta you prefer, but spaghetti holds the sauce beautifully.

• 2 cloves garlic, minced: Essential for that fragrant, savory aroma.

Must-Have Equipment

• Large pot: For boiling the spaghetti.
• Large skillet or frying pan: To cook the ground beef and sauté vegetables.
• Colander: To drain the pasta and canned tomatoes.
• 9×13 inch baking dish: The perfect size for layering and baking the casserole.

Directions: Baked Spaghetti Casserole Supreme

Step 1: Cook the spaghetti

Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain well and set aside.

Step 2: Prepare the meat sauce

While the pasta cooks, heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart, until browned and no longer pink. Drain excess fat if necessary. Add the chopped onion, minced garlic, and chopped bell pepper to the skillet. Sauté for about 5 minutes until vegetables are softened and fragrant.

Step 3: Add tomatoes and seasonings

Stir in the marinara sauce and drained diced tomatoes. Sprinkle in the dried oregano, dried basil, salt, and black pepper. Reduce heat to low and simmer the sauce for 10 minutes, stirring occasionally to meld the flavors.

Step 4: Mix cheeses

In a medium bowl, combine the cottage cheese, 1 cup of the shredded mozzarella, and the grated Parmesan. Stir until smooth and evenly mixed.

Step 5: Assemble the casserole

Preheat your oven to 375°F (190°C). In your baking dish, spread half of the cooked spaghetti evenly. Spoon half of the meat sauce on top, then dollop half of the cheese mixture over the sauce. Repeat layering with the remaining spaghetti, meat sauce, and cheese mixture. Finally, sprinkle the remaining 1 cup of mozzarella cheese evenly over the top.

Step 6: Bake

Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown on top.

Step 7: Garnish and serve

If using, sprinkle crumbled turkey bacon over the casserole as soon as it comes out of the oven for an added smoky crunch. Finish with a generous sprinkle of fresh parsley. Let the casserole rest for 5 minutes before serving to allow it to set.

This comforting dish pairs wonderfully with a crisp green salad or garlic bread for a complete meal. For more cheesy baked pasta inspiration, you might also enjoy trying Baked Cheesy Ravioli With Marinara or Baked Three Cheese Chicken Penne.

Adaptations for Special Diets

• Vegetarian: Swap the ground beef for plant-based crumbles or cooked lentils for a meat-free version.
• Lower fat: Use lean ground beef or substitute with ground turkey. Opt for low-fat cottage cheese and mozzarella.
• Dairy-free: Replace the cheeses with dairy-free alternatives like cashew cheese or vegan mozzarella.
• Gluten-free: Use gluten-free spaghetti to keep this dish safe for gluten-sensitive eaters.

Steer Clear of These

• Avoid overcooking the pasta; it should still have some bite since it will cook further in the oven.
• Do not skip draining the diced tomatoes thoroughly to prevent a watery casserole.
• Refrain from using pre-shredded cheeses with anti-caking agents if you want the best melt and texture.
• Avoid substituting with highly processed meats as toppings to keep the flavor clean and balanced.

Storage Pro Tips

Leftover Baked Spaghetti Casserole Supreme keeps beautifully in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the whole dish covered with foil in a 350°F oven until heated through. For longer storage, freeze the casserole before baking or after it has cooled completely. To freeze, wrap tightly with foil and plastic wrap and store for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reader Q&A

Can I make this casserole ahead of time?

Absolutely! Assemble the casserole a day before baking, cover it tightly, and refrigerate. When ready, bake as directed, adding a few extra minutes if it’s cold from the fridge.

Is turkey bacon necessary for this recipe?

Turkey bacon is optional and adds a smoky crunch topping, but the casserole is delicious on its own without it. You can omit it or replace with cooked mushrooms for a vegetarian crunch.

How can I prevent the casserole from drying out?

Make sure to keep enough sauce in the layers and avoid overbaking. Cover the casserole with foil for the first 20 minutes of baking if you notice the top browning too quickly.

Can I use fresh herbs instead of dried oregano and basil?

Yes, fresh herbs can be used. Use about three times the amount of fresh herbs compared to dried to maintain flavor balance. Add them towards the end of cooking to preserve their vibrant taste.
