Ingredients (Serves 6–8)

Core Ingredients

• 12 oz large or medium pasta shells
• 1 lb ground beef (or ground turkey)
• 2–3 bell peppers, diced (mix of green and red)
• 3 cups marinara sauce
• 2 cups shredded mozzarella or Monterey Jack cheese

Optional Additions

• ½ cup grated Parmesan
• ½ cup panko breadcrumbs
• 1 cup diced zucchini or spinach
• Fresh basil or parsley for garnish

Equipment Needed

• Large pot for boiling pasta
• Large skillet
• 9x13-inch baking dish
• Colander
• Mixing spoon

Step-by-Step Instructions

Step 1: Preheat and Prepare the Pasta

Preheat your oven to 375°F (190°C). Boil pasta shells in salted water until just shy of al dente, about 2 minutes less than package instructions. This ensures the shells finish cooking perfectly during the oven bake and absorb the sauce without becoming mushy.

Step 2: Brown the Protein

In a large skillet over medium-high heat, brown the ground beef until fully cooked. Drain excess fat to prevent a greasy casserole. This creates the savory base for your stuffed pepper pasta dinner.

Step 3: Add the Peppers

Add diced bell peppers to the skillet and sauté for 3–5 minutes. They should soften slightly while maintaining a subtle bite, giving this baked pasta dish texture contrast and classic stuffed pepper flavor.

Step 4: Stir in the Marinara

Lower heat and pour in the marinara sauce. Stir to combine thoroughly. This step merges the meat and vegetables into a cohesive, hearty pasta sauce perfect for an oven-baked casserole.

Step 5: Combine with Pasta

Add drained pasta shells to the skillet and toss gently until evenly coated. Alternatively, combine everything in a large mixing bowl. Transfer mixture into a greased 9x13-inch baking dish and spread evenly.

Step 6: Add the Cheese Topping

Sprinkle shredded cheese generously over the top. This creates the signature golden, bubbly crust that makes baked pasta casseroles so satisfying.

Step 7: Bake

Bake uncovered for 20 minutes, or until the sauce bubbles at the edges and the cheese is melted and lightly browned. Allow to rest 5 minutes before serving.

Pro Tips for the Perfect Stuffed Pepper Pasta Bake

• Drain meat thoroughly to avoid excess grease.
• Use high-quality marinara for deeper flavor in this simple casserole.

• Double the recipe for freezer meal prep.
