Wild Rice and Mushroom Casserole

Preparation

1. Step 1

   Taste broth; if bland, season to taste with salt. In a medium pot, bring broth to a boil over high heat. Stir in rice, lower heat, cover and simmer until just tender, about 40 minutes or according to package directions. Fluff rice with a fork, cover and let stand for 10 minutes.

2. Step 2

   Meanwhile, sauté vegetables: In a large, heavy skillet, heat 3 tablespoons oil over high heat. Add half the mushrooms and cook, stirring, until brown and crispy, about 8 minutes. Adjust heat as needed to prevent burning. Transfer cooked mushrooms to a plate and sprinkle lightly with salt. Repeat with remaining mushrooms and another tablespoon oil, adding more oil to the skillet if it looks dry.

3. Step 3

   In the empty skillet, heat 2 tablespoons oil over medium heat. Stir in leeks, fennel and 1 teaspoon salt; cook, stirring, until soft but not browned, about 8 minutes. Stir in spinach, chopped garlic, tomato paste and red pepper flakes, and cook until garlic starts turning golden, another 2 minutes. Remove skillet from heat.

4. Step 4

   Heat oven to 400 degrees, and oil a 9-by-13-inch casserole dish.

5. Step 5

   In a blender, purée 2 cans beans with their liquid, 2 tablespoons lemon juice, 1 grated garlic clove, and salt to taste. (If your beans are unsalted, they might need more than you’d think.)

6. Step 6

   Stir bean purée, remaining whole beans (drained), mushrooms, cilantro, parsley and cooked wild rice into skillet with vegetables. Taste and add more salt or lemon as needed; it should be well seasoned. Scrape into prepared baking dish.

7. Step 7

   In a small bowl, combine bread crumbs, rosemary, lemon zest, remaining 2 grated garlic cloves and ¼ teaspoon salt. Stir in ¼ cup olive oil and Parmesan, if using.

8. Step 8

   Sprinkle evenly on top of casserole and bake until golden, 20 to 30 minutes. Let cool slightly before serving, topped with flaky sea salt.
