A tian doesn't have too much to set it apart from its plainer cousins, but all the variations I've tried have had just an edge of sophistication, a dash of something special. Take this one, for instance, which I learned from Rosa Jackson, a food writer and teacher in Nice, France. It starts with a base of creamy, Parmesan-flecked orange squash, and bakes up with a green crust of garlicky herbed bread crumbs. You can practically taste the South of France: Olive oil, sun-kissed vegetables, garlic and rosemary. This is how the French do casseroles.
It is a little more involved than many of the other casseroles I make. You chop and cook the butternut squash (or pumpkin, or Red Kuri squash — my favorite) until it is soft. Then mash it up with a little parboiled rice to soak up any extra moisture, plus Parmesan and eggs. The topping is a scrumptious Provençal bread crumb mix of parsley, rosemary, olive oil, and garlic. Blended in the food processor, the crumbs turn bright green and make a delightfully colorful topping for the orange squash below.
Butternut Squash Tian with Herbed Bread Crumbs
Recipe adapted from Rosa Jackson. Serves 4
2 to 2 1/2-pound whole butternut squash
1 tablespoon olive oil, plus additional for drizzling
1/4 cup short-grain or arborio rice
2 ounces freshly grated Parmesan cheese
2 large eggs
Sea salt and freshly ground black pepper, to taste
Freshly grated nutmeg
Provencal breadcrumbs (recipe below)
Heat the oven to 375°F and lightly grease a 1 1/2 to 2-quart baking dish (such as a deep pie dish) with olive oil.
Peel and slice the butternut squash. You should have 1 1/4 to 1 1/2 pounds prepared squash flesh. Heat the olive oil in a deep sauté pan over medium heat. Cook the squash in the olive oil with a sprinkling of salt until it softens and starts to disintegrate, about 20 to 25 minutes. Cover for most of the cooking time to speed the process.
While the squash is cooking, heat a small saucepan of salted water over high heat. When it is boiling, add the rice. Cook for 10 minutes, then drain and set aside.
Place the cooked pumpkin in a large bowl and combine with the rice, Parmesan, about 1/2 teaspoon salt, and generous dashes of pepper and nutmeg. When it has cooled slightly, mix in the eggs quickly so that they don't scramble. The mixture may seem on the liquid side, but this is fine.
Pour it into the prepared gratin dish, top with the herbed bread crumbs (recipe below) and a generous drizzle of olive oil. (If desired, you can prepare to this point, cover and refrigerate for up to two days. When ready to serve, bake as directed below.)
Bake for 35 minutes or until slightly toasted on top and set. Serve warm.
This recipe doubles very well; I use a 4-pound squash and bake the tian in a 9x13-inch casserole dish.
Herbed Bread Crumbs
1 cup dried bread crumbs
1 big handful flat leaf parsley, leaves only
Leaves from 3 to 4 sprigs of thyme or rosemary
2 cloves garlic, peeled
2 tablespoons olive oil
Salt and freshly ground pepper
In a food processor, blend together all the ingredients except the olive oil. Add the olive oil and blend until the breadcrumbs are soft and green, adding a little more oil if necessary. Season well with salt and pepper.
Keep airtight in the refrigerator or freezer (in a plastic bag or jar) until you need them.
