Full Recipe (Ingredients + Instructions)

Ingredients 🍝

For the Meat Sauce

  • 1 pound ground beef
  • 1 pound Italian sausage, casings removed
  • 10 slices thick-cut bacon, chopped
  • 1 medium yellow onion, diced
  • 4 garlic cloves, minced
  • 1 jar (24 ounces) marinara or spaghetti sauce
  • 1 can (15 ounces) tomato sauce
  • 2 tablespoons tomato paste
  • 1 teaspoon Italian seasoning
  • 1 teaspoon dried oregano
  • ½ teaspoon smoked paprika
  • ½ teaspoon crushed red pepper flakes, optional
  • ½ teaspoon black pepper
  • Salt, to taste
  • 1 teaspoon sugar, optional

For the Pasta

  • 16 ounces spaghetti
  • 1 tablespoon salt for pasta water
  • 1 tablespoon butter

Creamy Cheese Layer 🧀

  • 8 ounces cream cheese, softened
  • 1 cup ricotta cheese
  • ½ cup sour cream
  • ½ cup grated Parmesan cheese
  • 1 teaspoon garlic powder
  • ½ teaspoon black pepper

For the Cheesy Top

  • 3 cups shredded mozzarella cheese
  • 1½ cups shredded sharp cheddar cheese
  • ½ cup grated Parmesan
  • Reserved crispy bacon
  • Fresh parsley, for garnish

Instructions

Step 1: Cook the Bacon 🥓

Add chopped bacon to a large skillet.

Cook over medium heat until crispy.

Transfer the bacon to a paper towel-lined plate.

Reserve about 2 tablespoons of bacon drippings in the skillet.

Set aside about ⅓ of the bacon for topping the casserole.

Step 2: Brown the Beef & Sausage 🥩

Add ground beef and Italian sausage to the skillet with the bacon drippings.

Add diced onion.

Cook for 7–10 minutes, breaking the meat into crumbles, until browned.

Drain excess grease if necessary.

Add garlic and cook for another 30–60 seconds.

Step 3: Make the Meat Sauce 🍅

Stir in:

  • Marinara sauce
  • Tomato sauce
  • Tomato paste
  • Italian seasoning
  • Oregano
  • Smoked paprika
  • Red pepper flakes
  • Black pepper

Add sugar if your tomato sauce tastes particularly acidic.

Stir most of the crispy bacon into the sauce.

Simmer over low heat for 15–20 minutes.

Step 4: Cook the Spaghetti

Bring a large pot of salted water to a boil.

Cook spaghetti until 1–2 minutes shy of al dente, according to package directions.

Don’t overcook—the pasta will continue cooking in the oven.

Drain and toss with butter.

Step 5: Make the Creamy Cheese Filling 🧀

In a bowl, combine:

  • Cream cheese
  • Ricotta
  • Sour cream
  • Parmesan
  • Garlic powder
  • Black pepper

Mix until creamy.

For an extra-smooth filling, let the cream cheese come completely to room temperature first.

Step 6: Assemble the Spaghetti Bake

Preheat oven to:

375°F (190°C)

Lightly grease a 9×13-inch baking dish.

Spread a thin layer of meat sauce over the bottom.

Then layer:

½ spaghetti → ½ meat sauce → creamy cheese mixture → 1½ cups mozzarella → remaining spaghetti → remaining meat sauce

Finish with:

  • Remaining mozzarella
  • Cheddar
  • Parmesan
  • Reserved crispy bacon

Step 7: Bake 🔥

Cover loosely with foil.

Bake for 20 minutes.

Remove the foil and bake for another 15–20 minutes, until the cheese is melted and the sauce is bubbling around the edges.

For a beautiful golden cheese top, broil for 1–2 minutes at the end.

Watch carefully so it doesn’t burn.

Step 8: Rest & Serve

This part is important!

Let the casserole rest for 10–15 minutes before slicing.

Finish with fresh parsley and a little extra Parmesan.

Then dig in! 🧀🍝

Extra Recipe Tips & Variations ✨

🌶️ Jalapeño Bacon Spaghetti Bake

Add 2–3 diced jalapeños to the meat mixture.

Pepper Jack cheese also works beautifully here.

🌶️ Green Chile Version

Add 1½ cups roasted Hatch green chile for a smoky Southwestern twist.

🧀 Five-Cheese Spaghetti Bake

Use:

  • Mozzarella
  • Cheddar
  • Parmesan
  • Provolone
  • Monterey Jack

The cheesier, the better!

🍄 Mushroom Version

Sauté sliced mushrooms with the onions before adding the meat.

🌶️ Spicy Italian Version

Use hot Italian sausage and extra crushed red pepper flakes.

🥓 Extra Bacon Version

Cook an additional 4–6 slices and sprinkle them over the casserole immediately before serving.

Flavor Upgrades / Secret Tips 🔥

✅ Don’t overcook the spaghetti. Slightly undercooked pasta holds up much better during baking.

✅ Cook the beef and sausage in a little bacon fat for extra flavor.

✅ Use freshly shredded cheese whenever possible—it melts more smoothly.

✅ Simmer the meat sauce before assembling so the flavors have time to develop.

✅ Keep some bacon aside for the top so you still get crispy bacon pieces.

✅ Let the finished casserole rest before slicing. Otherwise, the cheesy layers may fall apart.

Serving Ideas 🍽️

Serve with:

🥖 Garlic bread
🥗 Caesar salad
🥦 Roasted broccoli
🧄 Garlic knots
🥬 Fresh garden salad
🌶️ Pickled jalapeños

For the ultimate comfort-food dinner, serve a big square of spaghetti bake with garlic bread for soaking up the extra sauce.

Storage & Meal Prep Tips 🥡
