It transforms simple garden vegetables into a truly memorable meal.
What Exactly is a Gratin? Unveiling a Classic French Technique
The term “gratin” (pronounced grah-TAN, as in the French original) refers to a classic culinary technique that originated in France, characterized by a browned crust, often made of breadcrumbs, cheese, or both, which forms over the top of a dish when baked or broiled. The word “gratiné” literally means “to be scraped” or “to crust over,” referring to the delightful golden-brown layer that develops. This technique is applied to a wide array of ingredients, ranging from humble potatoes and various vegetables to more elaborate fish and poultry dishes.
What makes a gratin so beloved is its ability to transform simple ingredients into something extraordinary. The browning process intensifies flavors, creates a wonderful textural contrast between the crisp topping and the tender interior, and locks in moisture. It’s a method that promises warmth, comfort, and a touch of rustic elegance. While potato gratin (gratin dauphinois) is perhaps the most famous, the versatility of the gratin technique allows for endless creativity, making it perfect for showcasing seasonal produce like our vibrant yellow squash and tomatoes.
Crafting Your Own Yellow Squash and Tomato Gratin with Two Cheeses: A Step-by-Step Guide
Creating this delicious gratin is straightforward, but a few key steps ensure a perfectly structured and flavorful outcome. One crucial tip for working with fresh tomatoes is to remove excess moisture. Tomatoes, while wonderfully juicy, can release a significant amount of water during baking, potentially leading to a watery gratin. Pre-draining them ensures a firm, luscious texture.
Prepping the Tomatoes for Perfection: The Salting Method
- Begin by slicing your Roma tomatoes thinly and uniformly. Aim for about 1/4-inch thickness.
- Arrange the tomato slices in a single layer on a stack of paper towels. Sprinkle both sides generously with salt. The salt will draw out moisture from the tomatoes through osmosis.
- Allow the tomatoes to drain for at least 15 to 20 minutes. You will visibly see moisture being absorbed by the paper towels.
- Gently turn the slices over onto a fresh, dry section of paper towels and let them drain for another 15 to 20 minutes.
- Finally, blot the top side of the tomatoes dry with another clean paper towel to remove any remaining surface moisture. This step is vital for a gratin that holds its shape and isn’t soggy.
Assembling the Gratin: Layers of Flavor
- Lightly oil a gratin-style dish or a similarly shallow baking dish with 1 tablespoon of olive oil. This prevents sticking and helps create a lovely crust on the bottom.
- Arrange the first third of your thinly sliced yellow squash in a single, even layer at the bottom of the prepared dish. Season lightly with salt and freshly ground black pepper.
- Scatter a third of the fresh basil leaves and half of the chopped fresh garlic over the squash layer. The fresh herbs and garlic will infuse the entire dish with incredible aroma and flavor as it bakes.
- Carefully place half of the drained tomato slices over the squash, basil, and garlic. Ensure even coverage for a balanced bite in every spoonful.
- In a small bowl, combine the creamy ricotta cheese with one beaten large egg and a quarter cup of the freshly grated Parmesan cheese. This mixture acts as a luscious binder and adds incredible richness. Dollop half of this ricotta-Parmesan mixture over the tomato layer, spreading it gently. Sprinkle with 2 tablespoons of the remaining Parmesan cheese.
- Repeat the layering process: Add another third of the yellow squash, season with salt and pepper, layer with the remaining garlic, and a third of the basil leaves. Follow with the remaining tomatoes, the rest of the ricotta mixture, and another 2 tablespoons of Parmesan cheese. Top with a few more fresh basil leaves.
- Finish the gratin by arranging the final layer of yellow squash slices on top, then sprinkle generously with the remaining Parmesan cheese. This will create a beautiful cheesy crust.
- Evenly scatter the fresh breadcrumbs (preferably brioche for a richer flavor and texture) over the entire surface.
- Drizzle the remaining olive oil over the breadcrumbs. This helps them crisp up to a beautiful golden brown during baking.
- Preheat your oven to 400°F (200°C) and bake the gratin for 30-40 minutes. The gratin is ready when the cheese is bubbly, the breadcrumbs are golden brown and crisp, and the squash is tender when pierced with a knife. If the breadcrumbs begin to brown too quickly, you can loosely cover the dish with aluminum foil.
- Once baked, remove from the oven and let it rest for about 10 minutes before serving. This allows the layers to set, making it easier to serve clean portions.
And there you have it – a truly lovely, vibrant, and incredibly flavorful gratin! It’s the quintessential dish to make the most of those last glorious summer vegetables, delivering both comfort and gourmet appeal.
This beautiful gratin serves as the perfect side dish for any roasted meat or poultry, or stands proudly as a delicious vegetarian entree.

Summer Squash and Tomato Gratin
Equipment
-
Wusthof Chef Knife
-
Cutting Board
-
Gratin Baking Dish
-
Stainless Steel Mixing Bowls
Ingredients
- 3-4 large Roma tomatoes, thinly sliced
- Salt
- 1 cup ricotta cheese
- 1 large egg, beaten
- 3/4 cup freshly grated Parmesan cheese, divided
- 1/4 cup extra-virgin olive oil, divided
- 3 medium yellow squash, thinly sliced
- Freshly ground black pepper
- 15-20 whole basil leaves, torn if large
- 4 cloves garlic, chopped
- 1/2 cup fresh bread crumbs, preferably brioche
- Chopped fresh parsley, for garnish (optional)
Instructions
-
Slice the Roma tomatoes thinly and place them on paper towels. Sprinkle with 1 teaspoon salt and let stand for 15 minutes to draw out moisture. Flip onto fresh, dry paper towels and salt again, letting them stand for another 15 minutes. Blot the top side of the tomatoes dry with paper towels to remove any remaining surface moisture.
-
In a medium bowl, combine the ricotta cheese with the large beaten egg and 1/4 cup of the freshly grated Parmesan cheese. Mix well and set aside.
-
Preheat your oven to 400 degrees Fahrenheit (200°C).
-
Brush a gratin-style dish or another shallow baking dish with 1 tablespoon of the extra-virgin olive oil.
-
Arrange 1/3 of the thinly sliced yellow squash in a single layer at the bottom of the baking dish. Season lightly with salt and freshly ground black pepper. Top this layer with 1/3 of the fresh basil leaves and 1/2 of the chopped garlic. Next, add 1/2 of the drained tomato slices. Evenly spread 1/2 of the ricotta mixture over the tomatoes and sprinkle with 2 tablespoons of the remaining Parmesan cheese. Finish with a few more basil leaves.
-
Repeat the layering process: Add another 1/3 of the yellow squash, season with salt and black pepper, and scatter the remaining garlic and another 1/3 of the basil leaves. Follow with the remaining tomato slices, the rest of the ricotta mixture, and another 2 tablespoons of Parmesan cheese. Add a few more basil leaves.
-
Finish the gratin with the final layer of yellow squash slices and sprinkle with the remaining Parmesan cheese.
-
Evenly spread the 1/2 cup of fresh bread crumbs over the top layer of the gratin.
-
Drizzle the remaining olive oil over the breadcrumbs.
-
Bake for 30-40 minutes, or until the gratin is bubbly, golden brown on top, and the yellow squash is tender when easily pierced with a small knife. If the breadcrumbs start to brown too much before the squash is tender, cover the dish loosely with aluminum foil.
-
Let the gratin rest for 10 minutes after baking before serving immediately. Garnish with chopped fresh parsley if desired.
Notes
- For variety, you can easily use zucchini in place of yellow squash. A combination of both also works beautifully.
MAKE AHEAD:
- This gratin can be assembled up to 1 day in advance. Prepare all layers, but do NOT add the breadcrumbs and olive oil topping. Cover the dish tightly with plastic wrap and refrigerate.
- When you are ready to bake, remove the gratin from the refrigerator, scatter the breadcrumbs over the top, and drizzle with olive oil. You may need to increase the baking time by 5-10 minutes to account for the chilled temperature.
