“Ratatouille” Gratin

All of us love ratatouille, one of our favorite summer side dishes, especially for my grandson. So when I saw a recipe for a summer vegetable gratin it occurred to me that if I added some eggplant to it, it would be a ratatouille in a casserole with a nice crunchy top. Sounded delicious and indeed, it turned out succulent and indeed the top was very crunchy. The most important thing is to cut the vegetables all about the same so they cook at the same rate. It does take time since getting the water out of the squash and tomatoes, and the bitter out of the eggplant takes about a half hour of sitting but that time can be used to make really delicious caramelized onions. But it’s very easy to make. While I used yellow and zucchini squash, one or the other will work.

First thing is to cut up the vegetables:

1 pound zucchini squash, smallish, about 2

1 pound yellow summer squash, smallish again about 2

1 medium eggplant, peeled (about 6″ long)

6 medium size, ripe tomatoes

Wash and slice the squash, eggplant and tomatoes about 1/4 inch thick. Place the vegetables on baking trays covered with paper towels, sprinkle with salt and let sit for at least 1/2 hour. Wash off the salt (except from the tomatoes) and dry thoroughly between paper towels to get the squash and eggplant as dry as possible.

While the vegetables are sitting, cut:

3 large or 4 medium size onion

Peel and then cut them in half and slice each half into thin slices. Should have about 4 cups of onions. Heat in a 12″ skillet:

1 tablespoon olive oil

Add the sliced onions and cook for a minute over medium high heat before reducing to medium heat. Cook, uncovered, stirring every few minutes so that they don’t stick to the bottom of the skillet, for approximately 30 minutes or until golden brown. The heat may need to be reduced if they begin sticking. I wasn’t patient enough and mine didn’t get as brown as they should have but still tasted delicious.

Preheat oven to 400 degree. Spread in the bottom of a 9×13″ baking dish:

1 tablespoon olive oil

Begin by layering the squash.

Now layer the eggplant on top of the squash. Next, mix together:

3 tablespoons olive oil

2 teaspoons minced garlic

1 tablespoon fresh thyme (pull the leaves off the tough stems)

1/2 teaspoon of ground pepper (or to taste)

Sprinkle half the mixture over the eggplant and then turn the eggplant over so that the mixture also gets to the squash. Now layer the onions on top of the eggplant and then the tomatoes on the onions.

Sprinkle the remaining mixture (garlic oil) over the top of the tomatoes and again, turn over the tomatoes so the oil can mix with the casserole. Bake for about 40-45 minutes until the vegetables are tender and the tomatoes look a little brown. Remove from the oven and spread on top:

1 cup gluten-free bread crumbs, plain

1 cup dairy-free parmesan cheese, grated (Follow Your Heart makes an excellent one)

1 tablespoon fresh thyme (again, pull the small leaves off the tough stems)

1 tablespoon olive oil

Salt and pepper to taste (about 1/2 teaspoon salt and 1/4 teaspoon ground pepper)

Return to the oven and bake about 15 minutes more or until the topping has browned.

Sprinkle with:

1/4 cup roughly chopped basil

Feel free to half the recipe. The 9×13″ size will easily serve 8-10.
