Layers of sliced tomatoes and zucchini baked into a casserole with a dairy-free, grain-free, gluten-free cheesy tasting herb topping. If you enjoy dairy, finish the top with grated Parmesan.
Pre-heat an oven to 375° degrees. Slice tomatoes and zucchini crosswise into approximately ¼" slices.
Cook shallot and garlic
Add 1 tablespoon of olive oil to a small pan and heat oil over medium low heat. Add the shallot and cook until soft, about 2-3 minutes. Add garlic and cook another 30-60 seconds. Spread the soft shallots and garlic into the bottom of a 3-4 quart oval casserole.
Layer the vegetables
Layer the tomato and zucchini slices alternately around the dish, starting at the outside and working in, overlapping tightly. Get as much as you can into the dish. You may not use quite all of the slices. Sprinkle with the salt and pepper.
Create topping
Combine the parmesan, breadcrumbs, and herbs (or dairy-free sprinkle) then then scatter evenly over the top of the casserole. Drizzle with the last tablespoon of the olive oil.
Bake casserole
Bake casserole until top is golden and crisp, about 35-45 minutes. Timing will depend on your oven. Serve warm.
Notes
Dairy-free option: Omit the Parmesan and use a dairy-free Parmesan-style topping, or increase the breadcrumbs slightly and drizzle with a little extra olive oil.
