Slow-Cooker Vegetable Stew

Place tomatoes and their juice in a 4- to 7-quart slow cooker and crush them with your hands or a potato masher. Add cannellini beans, frozen beans, potatoes, onion, oregano, salt, pepper and crushed red pepper. Stir in broth and cover. Cook on Low for 8 hours or High for 4 hours.

To prepare croutons: About 30 minutes before serving, preheat oven to 400 degrees F. Mash chopped garlic into a paste with a fork or the side of a chef's knife. Transfer to a medium bowl and stir in 2 tablespoons oil and Italian seasoning. Add bread and toss to coat. Transfer to a rimmed baking sheet. Bake until golden, 12 to 15 minutes.

Just before serving, heat 1 tablespoon oil in a small skillet over medium heat. Add minced garlic and cook, stirring, until just golden, about 1 minute. Stir the garlic and oil into the slow cooker. Divide the stew among 6 bowls and top with the croutons. Serve with more crushed red pepper and Parmesan, if desired.
