Instructions

Preheat oven – to 375°F (190°C). Lightly grease a baking dish (8×8 or similar).

Layer veggies – Arrange alternating slices of zucchini and tomato in overlapping rows inside the baking dish. Season with salt, pepper, oregano, thyme, garlic, and a light drizzle of olive oil.

Notes & Tips

Add cheese layers: A little mozzarella or feta tucked between veggies makes it heartier.

Make ahead: Assemble ahead, refrigerate, and bake before serving.

Lighter topping: Swap breadcrumbs for almond flour for gluten-free.

Extra flavor: A drizzle of balsamic reduction before serving adds brightness.

Frequently Asked Questions 

Q: Can I use yellow squash instead of zucchini?
Yes — it adds more color and blends beautifully.

It’s best fresh, but leftovers keep 3 days in the fridge. Freezing can make the veggies watery.
