How to Make Zucchini Tomato Gratin

Prepare the Vegetables

Wash the zucchini and tomatoes, then slice them into even rounds. Keeping the slices similar in thickness helps everything bake at the same speed.

Season the Dish

Brush a baking dish with a little olive oil. Mix the minced garlic with the remaining oil, herbes de Provence, salt and black pepper.

Layer and Bake

Arrange the zucchini and tomato slices in overlapping rows. Add the mozzarella between the layers and drizzle the garlic oil over the top.

Bake at 190°C for 30 to 35 minutes, until the vegetables are tender and the cheese is melted and lightly golden.

Helpful Tips

If the tomatoes are very juicy, let the sliced vegetables rest for 10 minutes and pat them dry before baking. This keeps the gratin from becoming watery.

Serve it warm as a light dinner, or as a vegetable side dish with rice, chicken or grilled fish.

Conclusion

This zucchini and tomato gratin is easy, colorful and comforting. It is a practical recipe when you want a vegetable dish that feels generous without being complicated.
