Ingredients

• 2 19-ounce / 540g cans cannellini beans, rinsed and drained
• 1 19-ounce / 540g can garbanzo beans, rinsed and drained
• 1/2 cup / 70g chopped onion
• 1/4 cup / 60g basil pesto, divided
• 4 cloves garlic, minced
• 1 1/2 teaspoons dried Italian seasoning, crushed
• 1 16-ounce / 450g tube refrigerated cooked polenta, cut into 1/2-inch slices
• 2 cups / 8 oz finely shredded Italian cheese blend, divided
• 1 large tomato, thinly sliced
• 2 cups fresh spinach leaves
• 1 cup torn radicchio
• 1 tablespoon water

Instructions

1. In a large bowl, combine the rinsed cannellini beans, garbanzo beans, chopped onion, 2 tablespoons of the basil pesto, minced garlic, and Italian seasoning. Stir gently to combine.
2. Spread half of the bean mixture in the bottom of a 4- to 5-quart slow cooker. Top with a layer of half the polenta slices, followed by half of the shredded cheese (1 cup).
3. Repeat the layers with the remaining bean mixture and the remaining polenta slices. Cover the slow cooker and cook on the low setting for 4 to 6 hours or on the high setting for 2 to 2 1/2 hours.
4. Once cooked, carefully arrange the tomato slices over the top layer. Sprinkle with the remaining 1 cup of cheese. Top with the fresh spinach and radicchio.
5. In a small bowl, whisk together the remaining 2 tablespoons of pesto and 1 tablespoon of water. Drizzle this mixture evenly over the greens.
6. Let the dish stand, uncovered, for 5 minutes to allow the cheese to melt and the greens to wilt slightly before serving.

Pro Tips

• Pat the polenta slices dry with a paper towel before layering. This helps them hold their shape and prevents the casserole from becoming too watery.
• For an extra creamy texture, stir 1/4 cup of heavy cream or full-fat coconut milk into the bean mixture before layering.
• Feel free to swap the cannellini or garbanzo beans for other favorites like Great Northern beans or even black beans for a different flavor profile.
• Add the fresh spinach and radicchio at the very end as directed to ensure they just wilt perfectly without becoming overcooked and mushy.
