Summer Vegetable Gratin w/ Eggplant, Tomatoes, Chard, PestoRipe tomatoes and Walla Walla onions add a wonderful natural sweetness. Swiss chard adds a healthy measure of greens. Roasted eggplant adds complex flavor and a “meaty” texture. The 45 minute cooking time concentrates their flavors even more. And Pesto, as always, makes everything more delicious.

So what’s a gratin?
Gratin (pronounced as the French do: gra-TA) refers both to a baked French casserole with a crusty top, and to a shallow round or oval oven-proof dish in which the casserole is baked. Actually, a gratin can be baked in whatever heavy, shallow, ovenproof dish you have. Though, I do love my rustic 7 x 12- inch green oval gratin dish. It looks especially nice when set on the table for serving.Summer Vegetable Gratin w/ Eggplant, Tomatoes, Chard, Pesto

Healthier and lighter than traditional gratins, this recipe for Summer Vegetable Gratin recipe calls for less cheese and no breadcrumbs. Even without the usual crispy crust, it’s delicious. I’ve used two of my favorite cheeses, feta and soft goat cheese. Feel free to use another cheese such as mozzarella, cheddar, Gruyère or Parmesan if you prefer a cheese that melts a bit more. And, for an especially golden top crust, place your gratin under the broiler for the last few minutes of cooking.

Eggplant, aubergine, melanzana, ichiban, brinjal
Eggplants, known by many different names, appear in most every cuisine the world around. Right now, from August through October, this beautiful deep purple (lavender, jade green, orange or yellow-white!) vegetable has its prime season.

Summer Vegetable Gratin w/ Eggplant, Tomatoes, Chard, PestoWhen undercooked, eggplant has an unpleasantly tough texture. Oven-roasting the eggplant with a little olive oil before layering it in the gratin, assures tender, tasty and fully cooked eggplant. After a number of experiments, I found that a hot 450 degree oven yields the deepest golden and most tender slices of oven-roasted eggplant.

I picked up this endearing eggplant the other day at the Saturday market. Too adorable not to share with you. Grown by the lovely ladies from Running Strike Farms here in Bozeman.

Madison created this gratin after a violent hailstorm “shredded the chard and pockmarked the eggplant and tomatoes.” She added that this gratin is so moist and delicious “there’s no need to wait for a hailstorm to make this dish.”
