Tomato and Zucchini Casserole
Looking for zucchini and tomato recipes? Try this one. Summer markets are overflowing with beautiful tomatoes, zucchini, and fresh herbs, so turn them into a casserole. It's sort of a traditional summer French dish called a vegetable gratin, which is a fancy name for a casserole.
Many casseroles use cheese for richness and breadcrumbs for a crisp topping. This version is lighter and cleaner without cheese or breadcrumbs, yet still a crisp top and a cheesy taste. How? Using Vegan Cheese Powder.
Dairy-Free Vegan Cheese Powder
Vegan cheese powder is made with raw cashews, nutritional yeast, granulated garlic and sea salt. If you are not familiar with the wonderful cheesy flavor of nutritional yeast, read this post for more information. You can make a batch in a minute in a food processor. It provides a cheesy taste with no cheese, a nice alternative for dairy-sensitive or paleo diners.
Zucchini Casserole Ingredient Notes
For the casserole I use Roma tomatoes and green zucchini. Yellow zucchini is nice for added color if you can find it. Choose tomatoes and zucchini that are about the same diameter. When you slice and layer them the casserole looks nice and layers more easily. If they aren't quite even, it still works. You will need lots of fresh thyme, olive oil, garlic and a large shallot. If you don't have any shallot, use a little thinly sliced onion.
How to Assemble the Casserole
Use either an oval casserole baking dish called a gratin, oval roaster, or a rectangular baking dish. Use a 4 quart size. The dish in the photo is approximately 13" long, 10" wide and 2 ½ " deep. For a rectangular casserole, arrange the vegetables in rows rather than an oval.
Slice the tomatoes and zucchini crosswise into about ¼" thick circles. Sauté shallot and garlic in olive oil until soft and place it in the bottom of the casserole, then top with overlapping layers of tomatoes and zucchini. Pack the slices fairly tight as they shrink during baking. Sprinkle the topping over the top and bake uncovered until golden, about 35-45 minutes. Serve to the happy smiles of your family.
