Step-by-Step Instructions
- Boil the Pasta:
- Bring a large pot of salted water to a boil. Add penne and cook until al dente about ten to twelve minutes. Drain and set aside keeping a small cup of pasta water for adjusting the sauce later.
- Brown the Meats:
- Heat olive oil in a large skillet over medium high heat. Add ground beef and Italian sausage breaking into small pieces as it cooks. Stir until no pink remains and edges are lightly crisp. Drain excess grease to prevent a heavy dish.
- Sauté the Aromatics:
- Add chopped onion to the pan with the meat and cook about five minutes until soft and translucent. Add minced garlic and cook until fragrant about one minute. Stir in the squeezed spinach and heat through for two to three minutes before removing from heat.
- Make the Creamy Sauce:
- In a separate saucepan melt butter over medium heat. Whisk in flour for one minute to form a roux. Gradually add milk and chicken broth whisking constantly. Simmer gently until thickened about five to seven minutes.
- Finish the Sauce:
- Lower the heat and stir in heavy cream then add Parmesan, mozzarella, Cajun seasoning, Italian seasoning, and smoked paprika. Stir until cheese melts and sauce turns glossy and creamy.
- Combine Everything:
- In a large pot combine pasta, meat and spinach mixture, and sauce. Toss thoroughly to coat all pasta. Taste and adjust salt and pepper as needed.
- Optional Broil:
- Transfer to an oven safe dish, sprinkle more mozzarella on top, and broil a few minutes until bubbly and golden. Watch carefully to avoid burning.

My favorite part is how Parmesan melts into the sauce giving a subtle nutty flavor. I remember Sundays when everyone fought for the scoop with the most cheese which always makes me smile.
Storage Tips
Store leftovers in an airtight container in the fridge up to four days. Reheat with a splash of milk or broth to restore creaminess. Freeze in single portions for longer storage and gently reheat on the stove.
Ingredient Substitutions
Ground turkey or chicken works for a lighter version. Short pasta like rigatoni or ziti holds sauce well. Kale can replace spinach. Use coconut milk and plant based cheese for dairy free options.
Serving Suggestions
Pair with a fresh green salad and crusty bread to soak up extra sauce. Add diced bell peppers or sun dried tomatoes for a sweet and colorful twist.

Cultural Notes
This pasta bake is Italian American comfort food. The mix of sausage, beef, and cheese nods to classic pasta al forno while the hint of Cajun seasoning adds a unique twist.
