ZUCCHINI PESTO ORZO CASSEROLE

My new favorite pasta is orzo. It doesn’t really cook faster than other pasta, but it cooks about 10 minutes faster than rice.

This recipe cooks in 20 minutes and takes just under 10 minutes to prep, depending on how quickly you slice. Therefore, you can have this casserole on the table in less than 20 minutes.

Actually, even though it is meatless, we have it as our meal. You can always serve it alongside chicken, fish, or other protein.

Instructions

  • Preheat the oven to 400° F. In a 9×13 inch baking dish, combine the zucchini, olive oil, garlic, shallots, Italian seasoning, cayenne pepper, salt, and black pepper. Cook for 15 minutes.
  • Take the zucchini out of the oven. To the same pan, add the orzo and pesto. Pour over 2 and 1/2 cups of water over the ingredients and stir to combine.
  • Return the dish to the oven and bake for 14 to 16 minutes. Most of the water should be cooked into the pasta at this point. There may be a little in the bottom of the dish, but that's okay.
  • Stir the pasta around, then sprinkle over the cheese.
  • Bake another 10 minutes, until the cheese has melted and the sauce is bubbling. If there's a lot of oil from the pesto on top, drain off the excess. Top with fresh basil!

    This is a great garden meal with so much flavor! Was able to make fresh pesto from abundance of basil, used 2 zucchini and a yellow squash since my kids like those veggies. Easy to make and enjoyed not having to boil the pasta prior to baking. Will be making this again!

    1. I’m so happy you liked it. I love fresh veggies and this recipe is so easy. Thanks for commenting!

    Fast and easy, used 1 tablespoon of Italian seasoning since the amount was not listed in the ingredients. Loved the texture and I did use mozzerella cheese.
