How to Make Baked Mostaccioli Primavera – Step by Step

Step 1: Preheat the oven to 375°F (190°C).

Step 2: Cook the mostaccioli according to package directions until al dente, then drain and set aside.

Step 3: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté for about 5 minutes, until translucent.

Step 4: Add the minced garlic and cook for another minute until fragrant.

Step 5: Add the red and yellow bell peppers, chopped zucchini, and broccoli florets. Sauté for 7–10 minutes, until the vegetables are tender but still vibrant.

Step 6: Stir in the halved cherry tomatoes, Italian seasoning, and salt and pepper. Cook 1–2 minutes more to warm the tomatoes and blend the flavors.

Step 7: In a large mixing bowl, combine the cooked pasta with the vegetable mixture. Pour in the marinara sauce and toss until everything is evenly coated.

Step 8: Transfer the pasta and vegetables to a lightly greased 9×13-inch baking dish. Evenly sprinkle shredded mozzarella and grated Parmesan over the top.

Step 9: Bake for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden.

Step 10: Remove from the oven and garnish with chopped fresh basil before serving.

Helpful Tips

• Use fresh produce: Fresh vegetables deliver the best texture and flavor—avoid overcooking them when sautéing.
• Cook pasta al dente: The pasta will continue to cook in the oven; aim for slightly firm to the bite before baking.
• Cheese options: Try fontina, provolone, or gouda for a different flavor profile. Freshly grated cheese melts and browns more evenly than pre-shredded varieties.
• Sauce quality matters: Use a good-quality marinara or make a simple homemade tomato sauce for a brighter finish.

Serving Suggestions

This baked mostaccioli is versatile—pair it with simple sides to round out the meal:

• Warm garlic bread or a crusty loaf to soak up extra sauce.
• A crisp mixed green salad with a light vinaigrette for contrast.
• A glass of crisp white wine or a sparkling water with lemon for a refreshing complement.
