Ingredients

  • 3 bell peppers (yellow, orange or red) cored and cut into 1-inch wide strips
  • 2 zucchini quartered lengthwise and cut into 1-inch cubes
  • 2 summer squash quartered lengthwise and cut into 1-inch cubes
  • 8 cremini mushrooms halved
  • 1 yellow onion peeled and sliced into 1-inch strips
  • 1.5 Tbsp extra virgin olive oil
  • 1 tsp salt divided
  • 1 tsp ground black pepper divided
  • 2 tbsp dried Italian seasoning
  • 1/8 tsp crushed red pepper
  • 1 pound whole wheat penne pasta
  • 5 cups marinara sauce store bought or homemade
  • 1.5 cups frozen peas thawed
  • 1-1.5 cups shredded Italian cheese keep about 1/3 cup for the topping separate (I used a fontina, mozzarella & parmesan blend)

Instructions

  • Chop all the veggies and preheat your oven to 450 degrees
  • On a baking sheet (or in a casserole dish/large pan), toss the peppers, zucchini, squash, mushrooms, and onions with olive oil, 1/2 teaspoon salt, 1/2 teaspoon pepper, and dried herbs. Roast until tender, about 15 minutes.
  • Bring a large pot of salted water to a boil over high heat. Add the pasta and cook for about 6 minutes. Don't overcook your pasta! It will cook a second time in the oven, so you want to make sure the inside is still hard. Drain and set aside.
  • Once the veggies are done, toss the drained pasta with the roasted vegetables, marinara sauce, cheeses, peas, 1/2 teaspoon salt, and 1/2 teaspoon pepper. If you used a large casserole dish/pan to roast the veggies in, you can just dump all of the additional ingredients (pasta etc.) into that pan to mix everything together (that's what I'd recommend!). Using a wooden spoon, gently mix, until all the pasta is coated with the sauce and the ingredients are combined.
  • Top the pasta with the remaining cheese (about 1/3 cup).
  • Bake until top is golden and cheese melts, about 25 minutes. Let sit 5-10 minutes before serving.

Notes

Top tips for making Vegetarian Pasta Bake
  • Make sure to use a large, deep casserole dish for baking so that you can fit everything into one dish!
  • To save on cleanup, roast the veggies in the dish you're going to bake the pasta in.
  • You can make this ahead of time - follow the steps to step 5 in the recipe, then cover and keep in the fridge until ready to cook later that day.
  • Leftovers should be kept in an airtight container in the fridge - they will last for up to 4 days and gently reheated in the microwave or oven. You can also freeze this recipe in an airtight container - it will keep for up to 3 months! To reheat from frozen, defrost in the microwave on low and then heat in the oven on 350 until warmed through.
  • Don't overcook your pasta. I recommend cooking it for 50-60% of the time recommended on the package. It should still be a little hard inside when you drain it, and it will continue to cook while it’s in the oven.
