Ingredients

For the meat sauce:

1 pound ground beef
1 small onion finely diced
1 green bell pepper finely diced
2 teaspoons cajun seasoning
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon dried Italian seasoning
24 ounce jar marinara sauce

For the Alfredo layer:

½ cup unsalted butter
4 cloves garlic minced
2 cups heavy cream
2 cups shredded parmesan cheese
½ teaspoon kosher salt
½ teaspoon black pepper
16 ounces 1 pound spaghetti noodles, cooked to al dente

For the topping:

2 cups shredded mozzarella cheese
2 Tablespoons shredded parmesan cheese
2 teaspoons dried parsley flakes optional

Instructions

Preheat the oven to 350°F.
Spray a 9x13-inch baking dish with cooking spray, and set aside.
Start cooking the spaghetti noodles according to package directions.
In a large skillet over medium-high heat, add the ground beef, onion, bell pepper, cajun seasoning, garlic powder, onion powder, and Italian seasoning. Break up the beef into crumbles and cook, occasionally stirring, until the beef is no longer pink and the veggies have softened, about 10 minutes.
Drain any excess grease then stir in the marinara sauce and reduce the heat to low, simmer for 15 minutes, stirring occasionally.
While the meat sauce simmers, make the alfredo sauce.
In a dutch oven or large stock pot melt the butter over medium heat.
Add the garlic and cook for 30 seconds until fragrant.
Stir in the heavy cream, parmesan cheese, salt, and pepper.
Cook until the cheese has melted and the sauce thickens slightly.
Add the cooked spaghetti to the alfredo sauce and stir until the noodles are coated in the sauce.
Pour this mixture into the prepared baking dish.
Top with the meat sauce.
Sprinkle the mozzarella and parmesan cheese over the top.
Bake uncovered for 15 minutes until the cheese is melted.
Garnish with dried parsley flakes (optional) and serve!
