Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Bring a large pot of salted water to a boil. Add 12 oz penne pasta and cook for 8 minutes until just al dente, then drain and set aside.
  2. Step 2: While pasta cooks, heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 medium diced yellow onion and sauté for 3 minutes until translucent.
  3. Step 3: Add 1 medium diced zucchini, 1 diced red bell pepper, and 3 minced garlic cloves to the skillet. Cook for 5 minutes until vegetables soften and garlic is fragrant.
  4. Step 4: Stir in 28 oz canned crushed tomatoes, 1 tsp dried oregano, 1 tsp dried basil, 1 tsp salt, and 1/2 tsp black pepper. Simmer sauce for 8 minutes until slightly thickened.
  5. Step 5: Combine the cooked penne pasta with the tomato-vegetable sauce in a large mixing bowl, stirring gently to coat all pasta.
  6. Step 6: Transfer mixture to a 9x13 inch baking dish. Sprinkle 1 1/2 cups shredded mozzarella cheese evenly over the top, then 1/2 cup grated Parmesan cheese.
  7. Step 7: Bake uncovered for 20 minutes until cheese is melted and bubbly with golden edges. Let cool 5 minutes before serving.
