How to Make Best Minestrone Casserole
Step 1 – Prep the oven and baking dish
Preheat the oven to 350°F (180°C). Lightly coat a 3-quart baking dish with nonstick cooking spray.
Step 2 – Cook the pasta
Bring a large pot of water to a boil. Add the mafalda pasta and cook for the minimum time listed on the package, then drain and transfer to a large bowl.
Step 3 – Sauté the vegetables
Heat olive oil in a large skillet over medium heat. Add the onion, carrots, and celery, then cover and cook for 5 to 8 minutes, stirring occasionally, until the carrots are just tender.
Step 4 – Add zucchini and garlic
Stir in the zucchini and garlic. Cook for 1 minute more until fragrant.
Step 5 – Combine everything
Add the cooked vegetable mixture, kidney beans, cannellini beans, diced tomatoes, green beans, tomato sauce, 1/4 cup Parmesan cheese, Italian seasoning, salt, and black pepper to the bowl of pasta. Stir well until evenly combined.
Step 6 – Fill the baking dish
Transfer the pasta mixture to the prepared baking dish. Cover tightly with foil.
Step 7 – Bake and add cheese
Bake for 20 minutes. Remove the foil, top with mozzarella cheese, and continue baking for 10 to 15 minutes until hot and the cheese is melted.
Step 8 – Finish and serve
Top each serving with the remaining Parmesan cheese and sprinkle with chopped fresh basil and/or oregano. Serve warm.
