Do you have an abundance of brilliant summer vegetables? Are you looking for an easy and delicious dinner that makes wonderful leftovers? Then this zucchini rice gratin in what you're looking for...
Enough of my sales pitch. This dish is delicious. And while zucchini and tomatoes are at their best this time of year, you could make this year-round. It will remind you of summer and possibly even evoke memories of Provence, whether you've been there (lucky!) or not (ahem, like me).
Zucchini Rice Gratin
from Gourmet: Easy Dinners special edition magazine (get the original recipe here)
Makes a 2-quart baking dish full of gratin (4-6 servings)
Ingredients:
1 cup long-grain white or brown rice
2 lbs. zucchini (about 4 medium), sliced into 1/4-inch thick rounds
8 tbsp. olive oil, divided
1 lb. plum tomatoes, sliced 1/4-inch thick
1 medium onion, thinly sliced
3 garlic cloves, finely chopped
6 large eggs, lightly beaten
1 tsp. chopped thyme
1 cup grated Parmesan-Reggiano, divided
Preparation:
Preheat oven to 450 degrees F with racks in upper and lower thirds.
Cook rice according to box instructions.
While rice cooks, toss zucchini with 2 tbsp. olive oil and 1/4 tsp. salt, then spread in a single layer on a baking sheet. Toss the tomatoes with 1 tbsp. olive oil and 1/4 tsp. salt, then spread in a single layer on a second baking sheet. (It's annoying to use 2 sheets, but they cook for different times.)
Roast zucchini on upper rack in the oven for 20 minutes, flipping slices over at halfway through roasting. Roast tomatoes on the bottom rack for 10 minutes, turning over halfway through roasting. You are pre-cooking the veggies here, and don't want them to be fall-apart-mushy roasted at this point; you'll cook them a bit more later.
While the zucchini and tomatoes roast in the oven, cook the onion and garlic in 2 tbsp. olive oil and 1/4 tsp. salt in a large heavy skillet over medium-low heat, covered and stirring occasionally. Cook until soft, about 10 minutes.
Time to assemble the gratin. Butter a shallow 2-quart baking dish. Stir together the cooked rice, cooked onions, beaten eggs, 2/3 cup Parmesan-Reggiano cheese, 1 tbsp. olive oil, 1/4 tsp. salt, 1/2 tsp pepper, and thyme. Spread half of this mixture in the baking dish and layer half the roasted zucchini on top.
Spread the remaining rice mixture on top and layer the remaining roasted zucchini on top of the second rice layer. Top with the roasted tomatoes and drizzle with 2 tbsp. olive oil. Sprinkle with 1/3 cup Parmesan-Reggiano cheese (or more, I won't tell).
Bake on upper rack of the oven until set and golden brown, about 20 minutes.
The rice-egg-cheese mixture bakes into an almost custard-like consistency and makes this gratin a substantial meal, with roasted seasonal vegetables and a light crust of browned cheese. It's also fantastic and easy as leftovers -- just reheat in the microwave and dig in!
