Ingredients

  • 2 cups broccoli florets, chopped
  • 1 cup diced bell peppers (red, yellow, or green)
  • 1 cup sliced mushrooms
  • 1 medium carrot, diced
  • 1 small onion, finely chopped
  • 3 cloves garlic, minced
  • 2 cups shredded cheddar cheese (or a cheese blend)
  • 1 cup shredded mozzarella cheese
  • 2 cups milk (whole or 2%)
  • 3 tbsp all-purpose flour
  • 3 tbsp unsalted butter
  • 1 tsp dried Italian herbs (oregano, basil, thyme mix)
  • Salt and pepper to taste
  • 1/2 cup grated Parmesan cheese (optional, for topping)
  • 2 tbsp olive oil (for sautéing vegetables)

Equipment

  • Large pot for boiling pasta
  • Large skillet or frying pan
  • Medium saucepan for cheese sauce
  • 9×13 inch casserole dish
  • Mixing bowls
  • Wooden spoon or spatula
  • Whisk
  • Measuring cups and spoons
  • Colander

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Cook the pasta shells: Bring a large pot of salted water to a boil. Add the pasta shells and cook according to package instructions until al dente, usually about 8-10 minutes. Drain and set aside.
  3. Sauté the vegetables: Heat 2 tbsp olive oil in a large skillet over medium heat. Add the onions and garlic and sauté for 2-3 minutes until fragrant. Add the carrots, bell peppers, mushrooms, and broccoli. Cook for 5-7 minutes until the vegetables are tender but still crisp. Season with salt, pepper, and Italian herbs. Remove from heat.
  4. Prepare the cheese sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour to form a roux and cook for 1-2 minutes, stirring constantly. Slowly add the milk, whisking continuously to avoid lumps. Cook until the sauce thickens, about 5 minutes.
  5. Add cheese to the sauce: Remove the saucepan from heat and stir in 1 1/2 cups cheddar cheese and 1/2 cup mozzarella cheese until melted and smooth. Season with salt and pepper to taste.
  6. Combine pasta, vegetables, and cheese sauce: In a large mixing bowl, combine the cooked pasta shells, sautéed vegetables, and cheese sauce. Mix gently but thoroughly to ensure everything is coated evenly.
  7. Assemble the casserole: Transfer the pasta mixture into the greased 9×13 inch casserole dish. Sprinkle the remaining cheddar and mozzarella cheese on top. Optionally, add the grated Parmesan for an extra cheesy crust.
  8. Bake: Place the casserole in the preheated oven and bake for 20-25 minutes, until the cheese is bubbly and golden brown on top.
  9. Rest and serve: Remove from oven and let the casserole rest for 5-10 minutes before serving. This helps it set and makes serving easier.

Tips & Variations

Tip: For a creamier sauce, substitute half the milk with heavy cream or use a combination of milk and vegetable broth.

Variation: Swap out cheddar and mozzarella for pepper jack or gouda for a different flavor profile.

Vegetable options: Feel free to add spinach, zucchini, or peas to the vegetable mix for added texture and nutrients.

Make it vegan: Use dairy-free cheese alternatives and plant-based milk, and sauté vegetables in olive oil or vegan butter. For a vegan cheese sauce, check out our Cauliflower Vegan Cheese Sauce Recipe for Easy Dips.
