Tomato Zucchini Casserole: No Cheese or Gluten

Summer markets are overflowing with beautiful tomatoes, zucchini, and fresh herbs. Ever turn them into a casserole? Its sort of a traditional summer French dish, a vegetable gratin, which is a fancy name for a casserole. Many casseroles use cheese for richness and breadcrumbs for a crisp topping. My version is lighter and cleaner without cheese or breadcrumbs, yet still a crisp top and a cheesy taste. How? Using the dairy-free cheesy sprinkle recipe I posted recently.

Dairy-Free Cheesy Sprinkle

Dairy-free cheesy sprinkle 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, so great for dairy-sensitive or paleo diners.

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 you could use a little thinly sliced onion.

How to Assemble the Casserole

Use an oval casserole dish called a gratin, oval roaster, or oval casserole. Use a 4 quart size. My dish is approximately 13″ long, 10″ wide and 2 1/2 ” deep. You can also use a rectangular casserole. Just arrange the vegetables in rows rather than an oval.

Slice the tomatoes and zucchini crosswise into about 1/4″ 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 will 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.

Perfect! It looks delicious! I am testing different yeast powder for a best taste. I bought one that I didn’t like at all. It smells bad! What brand are you using?
