Easy Zucchini and Squash Gratin
Ingredients
- ¾ lb. zucchini
- ¾ lb. yellow summer squash
- 2 tablespoons olive oil divided
- ½ teaspoon minced garlic
- ½ cup finely-diced onion
- 1 cup canned unsalted crushed plum tomatoes in juice
- 1 tablespoon fresh basil
- 1 tablespoon fresh parsley
- ½ teaspoon salt
- ¼ teaspoon pepper
- 3 tablespoons grated Parmesan cheese
Instructions
- Preheat oven to 400°F (200°C). Spray a medium-sized baking dish with cooking spray and set aside (I used a deep 5-inch by 9-inch dish, but a 7x11-inch dish or anything similar in size will work well).
- Slice zucchini and squash into thin rounds (I like to use a mandolin to make it fast and uniform, but it’s not necessary).
- In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add garlic and cook (stirring constantly) for about 1 minute. Add zucchini and squash to the skillet. Stir and cook until vegetables are tender (about 5-6 minutes). Remove from heat.
- In a small saucepan, add remaining 1 tablespoon of oil and diced onion. Cook onion over medium heat until translucent (about 2 minutes), and then add the tomatoes (with their juice) and the basil. Simmer tomatoes about 5 minutes. Stir in parsley, salt, and pepper to taste.
- Spread half of the zucchini/squash mixture into the bottom of the prepared baking dish. Cover with half of the tomato sauce from the saucepan, and sprinkle with 1 tablespoon of grated Parmesan.
- Add another layer with the remaining zucchini, top with the remaining sauce, and finish with the last 2 tablespoons of Parmesan.
- Bake for 15 minutes, or until cheese is melted and the top becomes golden brown.
- Allow dish to sit for about 10 minutes before serving.

I have soooo many zucchini in my house right now and IDK what to do with them! But now I know;) This gratin looks incredible!
Blair
Thanks so much, Bethany! I feel the same way -- what the heck do I do with all of the cucumbers, zucchini, and squash that are coming into my house right now! 🙂 There could be worse problems, I realize!
Gayle @ Pumpkin 'N Spice

Such a beautiful, summer dish, Blair! I'm sharing this on the farms' FB's today. Everyone has so much zucchini right now 🙂

Omg you have my childhood zucchini favorite. I have not seen this recipe anywhere else. I make it and we all love it. My only addition since childhood is add-ons lots of Ritz crackers and mozzarella cheese on top. We like the gooie crunchie topping. We called it zucchini pizza. Thanks for fond memories.
Blair
So simple, but so good, right?! I'm so glad that this dish brings back good memories. I love the idea of adding Ritz crackers and mozzarella. YUM!

Can you use fresh tomatoes in this recipe?
Blair
Hi, Betsy! Yes, you can -- but the texture will be different. The crushed tomatoes have a texture that's more like sauce, while the fresh tomatoes will retain their shape.
