Preheat your oven to 350°F and cook ziti al dente according to the directions on the box.
Prep your vegetables by dicing the zucchini and onion, slicing the mushrooms, and mincing the garlic.
Add the prepped veggies to a large saucepan or pot with spinach, olive oil, salt, and pepper. Cook over high heat until the liquid from the veggies releases and the onion turns translucent (10-15 minutes).
Add the marinara sauce to the saucepan and continue to cook for another 2 minutes, stirring frequently, until the sauce thickens.
Remove from heat and stir in the ricotta.
Add your cooked pasta to the veggie-packed sauce and stir to coat. Transfer the ziti and sauce to a 9 x 13-inch baking dish.
Layer the shredded Italian cheese blend on top, completely covering the ziti with cheese.
Bake for 25-30 minutes until the top layer of cheese is completely melted and starts to brown. Option to garnish with fresh basil. Enjoy!
Pro Tips
If you're not a fan of mushrooms you can easily sub in any other vegetable like peppers, eggplant, or even fresh tomatoes.
You can use yellow squash, butternut squash, or summer squash in place of zucchini. Or leave it out entirely!
