Johnny Marzetti Casserole is a glorious, hearty monument to American comfort food, a dish born from community kitchens and potluck traditions that delivers unmatched satisfaction in every forkful. This recipe elevates the classic midwestern baked pasta by building layers of robust flavor, starting with a savory foundation of ground beef and Italian sausage that provides a rich, meaty depth. The magic deepens with the addition of earthy cremini mushrooms, sweet onions, and vibrant bell peppers, all sautéed in the rendered meat fats until tender and caramelized. This aromatic medley is then simmered in a simple yet potent tomato sauce, infused with garlic, thyme, and marjoram, creating a chunky, rustic ragù that clings perfectly to every twist of corkscrew rotini pasta. Baked under a generous, bubbling blanket of both sharp cheddar and Italian cheese blends, the casserole emerges as a unified, golden-brown masterpiece of melted cheese and savory goodness.
The brilliance of this recipe lies in its harmonious balance and crowd-pleasing simplicity. It is a complete, one-dish meal that masterfully combines protein, vegetables, pasta, and cheese into a comforting, cohesive whole. The use of two cheeses—sharp cheddar for a tangy punch and a melty Italian blend for gooey richness—creates a complex, irresistible topping. Unlike many baked pastas that can become dry or heavy, this version maintains a perfect sauciness, ensuring each bite is moist and flavorful. It’s the quintessential feed-a-crowd dish: forgiving to make, easy to transport, and guaranteed to elicit contented sighs around the dinner table. Johnny Marzetti is more than a casserole; it’s a edible piece of culinary heritage, offering warmth, abundance, and the deeply comforting promise of a meal made with care.

Ingredients:
For the Pasta & Meat Base:
12 ounces (340g) rotini pasta
1 lb lean ground beef
½ lb ground Italian sausage (mild or hot)
8 ounces cremini mushrooms, sliced
1 medium yellow onion, sliced
1 medium red bell pepper, diced
4 cloves garlic, minced
1 teaspoon dried thyme
½ teaspoon dried marjoram
For the Sauce & Assembly:
1 (15-ounce) can tomato sauce
1 (15-ounce) can diced tomatoes, undrained
2 cups (8 oz / 226g) shredded sharp cheddar cheese
1 ½ cups (6 oz / 170g) shredded Italian cheese blend (mozzarella, provolone, Asiago, etc.)
Kosher salt and freshly ground black pepper, to taste
Non-stick cooking spray or olive oil for greasing
Instructions:
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with non-stick spray or olive oil.
Step 2: Cook the Pasta
Bring a large pot of generously salted water to a boil. Cook the rotini according to package directions until just al dente (it will cook further in the oven). Drain well and set aside.
Step 3: Brown the Meats and Vegetables
While the pasta cooks, in a large skillet or Dutch oven over medium-high heat, cook the ground beef and Italian sausage, breaking it up with a spoon. When the meat is about halfway browned (after 4-5 minutes), add the sliced mushrooms, onion, and bell pepper. Continue cooking, stirring occasionally, until the meat is fully browned and the vegetables have softened, about 6-8 more minutes.
Step 4: Build the Sauce
Reduce the heat to low. Add the minced garlic, thyme, and marjoram to the skillet and cook, stirring constantly, for 1 minute until fragrant. Stir in the tomato sauce and diced tomatoes with their juices. Season the mixture generously with salt and pepper. Bring to a simmer and let it cook for 5 minutes to allow the flavors to meld.
Step 5: Combine and Assemble
In the prepared baking dish, combine the drained pasta and the meat sauce. Stir until the pasta is evenly coated. Spread the mixture into an even layer. Sprinkle the shredded cheddar cheese evenly over the top, followed by the Italian cheese blend.
Step 6: Bake
Bake, uncovered, for 20-25 minutes, or until the cheese is completely melted, bubbly, and just beginning to turn golden in spots.
Step 7: Rest and Serve
Remove from the oven and let the casserole rest for 5-10 minutes before serving. This allows it to set slightly for cleaner portions.
Tips:
- Don’t Overcook the Pasta: Cook it to al dente, as it will absorb moisture and soften further in the sauce during baking.
- Drain Excess Fat: If your meat mixture seems very greasy after browning, you can drain off some excess fat before adding the garlic and tomatoes for a less oily final dish.
- Customize the Vegetables: Add a cup of frozen corn, diced zucchini, or sliced olives when you add the tomatoes for extra flavor and nutrition.
- Cheese Flexibility: Feel free to use all cheddar, all Italian blend, or add a cup of ricotta dolloped over the sauce before topping with the shredded cheeses.
- Make it Spicy: Use hot Italian sausage and add a pinch of red pepper flakes with the garlic for a kick.
Storage Options:
- Refrigerator: Store leftover casserole, covered tightly, in the refrigerator for up to 4 days.
- Reheating: Reheat individual portions in the microwave. For larger amounts, reheat, covered with foil, in a 325°F (165°C) oven for 20-25 minutes, or until heated through.
- Freezing: Assemble the casserole but do not bake. Wrap the dish tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the refrigerator and bake as directed, adding 10-15 minutes to the baking time.
- Make-Ahead: You can assemble the entire casserole up to 24 hours in advance. Cover and refrigerate. Bake as directed, adding 5-10 minutes to the bake time since it will be cold.
Johnny Marzetti Casserole is the epitome of hearty, no-fuss, family-pleasing cooking. It takes simple, accessible ingredients and weaves them into a cheesy, savory, and utterly comforting masterpiece that promises to become a requested favorite in your home for years to come.
