Recipe Ingredients

• 375 g (13 oz) great northern, navy, or haricot beans, soaked overnight, drained, and rinsed
• 1 medium onion, finely chopped
• 500 ml (2 cups) vegetable stock
• 500 ml (2 cups) water
• 2 tbsp maple syrup
• 2 tbsp treacle or molasses
• 1 tbsp smoked paprika
• ½ tsp cayenne pepper (optional, for a touch of heat)
• 2 garlic cloves, finely chopped
• 2 tbsp Dijon mustard
• 1 x 400 g (14 oz) tin chopped tomatoes
• 1 fresh or dried bay leaf
• Toasted crusty bread, for serving
• Fresh parsley leaves, for garnish

How To Make Slow Cooker Boston Beans

1. Prepare the Beans: After soaking the beans overnight, drain and rinse them thoroughly under cold water.
2. Cook on the Stovetop: In a large saucepan, combine the beans, chopped onion, vegetable stock, and 500 ml (2 cups) of water. Bring the mixture to a boil over medium-high heat, then let it simmer for 10 minutes. Skim off any foam or impurities that rise to the surface for a cleaner dish.
3. Transfer to the Slow Cooker: Carefully pour the contents of the saucepan into your slow cooker.
4. Add Flavorful Ingredients: Stir in the maple syrup, treacle or molasses, smoked paprika, cayenne pepper (if using), garlic, Dijon mustard, chopped tomatoes, and the bay leaf. Mix everything well to combine.
5. Cook Low and Slow: Set your slow cooker to the low setting and let the beans cook gently for 8 hours. By the end, the beans should be tender and infused with the rich, smoky flavors of the sauce.
6. Final Touches: Once cooked, discard the bay leaf and taste the beans. Adjust the seasoning with salt and pepper, if needed.
7. Serve and Enjoy: Ladle the beans into bowls and serve with slices of toasted crusty bread. Garnish with fresh parsley leaves for a pop of color and freshness.

Recipe Tips

• Use Canned Beans for Convenience: If you’re short on time, swap dried beans for canned ones. Rinse and drain them well, then reduce the cooking time to 4 hours on low.
• Add More Vegetables for Nutrients: Enhance the dish by adding diced carrots, celery, or bell peppers. Sauté them before adding to the slow cooker for extra depth of flavor.
• Make It Spicier: If you enjoy heat, increase the cayenne pepper or add a chopped fresh chili. A dash of hot sauce at the end also works well.
• Sweeten It Your Way: Replace maple syrup with honey, agave nectar, or brown sugar. Each sweetener adds a slightly different flavor profile to the sauce.
• Serve It Creatively: Try serving the beans over fluffy white rice, mashed potatoes, or as a filling for baked sweet potatoes for a hearty twist.
