Thanks to my friend Diane, I went to see a movie and came home with a cornucopia of fresh, organic produce. Diane, a Master Gardener who specializes in edible gardens, had been to a garden swap and brought two huge baskets full of veggies, including some unique varieties of heirloom tomatoes, peppers, eggplant, etc. with names I don’t remember, and encouraged us to take whatever we wanted. It was a veritable farmers market in the Regal Cinema’s parking lot!
Now, with a huge bowl of veggies from Diane and my garden on my kitchen counter, I set to thumbing through my cookbooks and the gorgeous two-page photo spread of the mise-en-place for Summer Vegetable Gratin in Thomas Keller’s Ad Hoc At Home caught my eye. Here tomatoes, squash, and eggplant are layered on a cooked onions and baked with a cheese and bread crumb topping. I actually sliced an eggplant but didn’t use it because my baking dish was smaller than the 9×13 suggested.
The recipe states that this is a good dish to assemble ahead and then bake before serving. But I ended up hurrying to slice everything up and get it in the oven as soon as the Young Baker was finished making the cookies she was taking to a sleepover. I made fresh bread crumbs, but in my hurry forgot to sprinkle them on top! Not to worry, this didn’t stop us from devouring every bit of this gratin down to the delicious juices in the bottom of the baking dish.
Summer Vegetable Gratin
(adapted from Ad Hoc at Home)
1 medium yellow squash
1 medium zucchini
1 medium tomato
Canola oil
1 c. onion, chopped
2 garlic cloves, finely grated with a Microplane
sea salt
1 tablespoon fresh thyme, chopped
¼ c. extra virgin olive oil
freshly ground pepper
½ c. freshly grated Parmesan cheese
Serves 4
Thinly slice (¼ inch) the yellow squash, zucchini, and tomato as close in size as possible.
Heat some canola oil in a large frying pan over medium heat. Reduce to med-low, add the onions and garlic and cook without browning, stirring occasionally, until the onions are translucent, about 15 minutes. Remove from burner. Stir in the thyme.
Combine the yellow squash and zucchini in a large bowl and toss with the olive oil, and season with salt. Drizzle the slices of tomato with olive oil and season with salt.
Combine the Parmesan, bread crumbs, and thyme.
Spread the onion mixture in the bottom of an 8½ inch round shallow baking dish. Layer the vegetables in the dish overlapping the slices in a circle beginning with the zucchini. Then a circle of yellow squash overlapping the zucchini and ending up with a center of overlapping tomato slices. Sprinkle with half the cheese mixture and continue making overlapping rows with the remaining vegetables, and sprinkle with remaining cheese mixture.
Bake for 45 minutes to 1 hour (depending on the depth of your pan) until the vegetables are tender (can be pierced easily with a knife). Remove from the oven and allow the gratin to rest for 10 minutes. If desired, turn on the broiler and place the gratin under the broiler to brown the top just before serving.
