Farro White Bean And Broccoli Rabe Gratin Make Ahead Recipe From Cooks Illustrated

Steps:

• Tear broccoli rabe or kale leaves into bite-size pieces and set aside. Chop the stems into about 1/4-inch pieces; set aside.
• Heat 1/4 cup olive oil in a large pot over medium heat. Add garlic and onion, and season with salt and pepper. Cook, stirring occasionally, until lightly browned and sizzled at the edges, 4 to 6 minutes.
• Add harissa (or tomato paste and a pinch of red-pepper flakes), and stir to coat in the oil. Cook until the harissa is a nice brick red color, the sugars start to caramelize and the oil turns a nice vibrant fiery orange color, about 2 minutes.
• Add beans, and season with salt and pepper. Using a wooden spoon or spatula, crush a few beans to release their creamy interior.
• Add the broth and reserved stems, and season with salt and pepper. Bring to a simmer and cook until you've reached your desired consistency (less time for a brothier soup, more time for a thicker stew), 15 to 20 minutes.
• Add broccoli rabe or kale leaves and preserved lemon or lemon juice, and stir to wilt the greens. Season with salt, pepper and more red-pepper flakes if you want it spicier.
• Serve with feta and parsley, and with eggs, if you like.
