Creamy White Bean and Fennel Casserole

Step 1

Heat the oven to 425 degrees. Trim the fennel. Cut it in half lengthwise and slice it crosswise, about 1/4-inch thick (reserve about 1/4 cup roughly chopped fennel fronds). Heat 2 tablespoons oil in a large cast-iron skillet over medium. Add the sliced fennel, season with salt and pepper and cook, stirring occasionally, until softened but still retaining a little bite, about 12 minutes. Stir in the garlic and cook until fragrant, 1 to 2 minutes.

Step 2

Meanwhile, pour 1 can white beans and its liquid into a blender. Add the heavy cream, lemon juice and 2 tablespoons olive oil and purée until smooth. Drain and rinse the remaining can of beans and transfer it to the skillet along with the bean purée. Season generously with salt and pepper.

Step 3

Mix the panko with the remaining 2 tablespoons olive oil in a small bowl. Add the Parmesan, lemon zest and 1/2 teaspoon pepper and toss to coat. Sprinkle evenly over the fennel-white bean mixture.

Step 4

Bake until bubbly and lightly golden on top, about 15 minutes. Broil until topping is browned in spots, 1 to 2 minutes, if desired. Top with reserved fennel fronds and serve.
