This Easy Vegetarian Ziti Casserole Recipe is super easy to make and perfect for a weeknight! You can make it with regular pasta or gluten-free pasta.

In fact, studies show that vegetarians tend to have better diet quality than meat-eaters and a higher intake of important nutrients like fiber, vitamin C, vitamin E and magnesium. A vegetarian diet may provide several other health boosts as well.

Add your favorite veggies to this ziti casserole! And the more cheese the better! Yummy. If you aren’t crazy about ricotta cheese, you can use cream cheese instead. I love the creaminess of cream cheese more than ricotta, but ricotta makes it taste more like a lasagna.

It’s so easy to cook the pasta separately and then mix up the ricotta with vegetables in a bowl. If you want to sauté anything like fresh spinach or zucchini, you can do that while the ziti is cooking.

I’ve made this with homemade red sauce but I prefer to buy my favorite spaghetti sauce. It’s so much easier and less mess and more flavorful. But if you know how to make good spaghetti sauce, go for it!
