Ingredients for Slow Cooker Rustic Ratatouille with White Beans

Instructions

Prepare all vegetables: dice the eggplant, slice the zucchini into half-moons, dice the bell peppers, and chop the onion and garlic.
In a large mixing bowl, combine the eggplant, zucchini, red and yellow bell peppers, onion, and garlic.
Add the canned diced tomatoes with their juice, tomato paste, white beans, and vegetable broth (or water) to the bowl.
Sprinkle in the dried thyme, oregano, rosemary, smoked paprika, and add the bay leaf. Season with salt and freshly ground black pepper to taste.
If using, pour in the dry white wine and drizzle the olive oil over the mixture. Toss gently to combine all ingredients evenly.
Transfer the vegetable and bean mixture into the slow cooker crock, spreading it out evenly.
Cover and cook on low for 6 hours or on high for 3 to 4 hours until vegetables are tender and the flavors have melded beautifully.
About 30 minutes before serving, remove the bay leaf. Taste and adjust seasoning with additional salt and pepper if needed.
Serve warm, garnished with fresh chopped basil and parsley. Enjoy alongside crusty bread or over cooked grains like rice or quinoa, if desired.
Store any leftovers in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months.
