🥘Ingredients

• canned cannellini beans- the creamiest of the canned white beans, and because they're already pre-cooked, the soup doesn't need to cook as long
• carrots- sliced or julienned (I sometimes use matchsticks from the store to save time), they provide some sweetness to the soup
• celery- sliced or chopped for added flavor
• white onion- a white bean soup deserves a white onion; Vidalia onions are a little sweeter and the best choice for this recipe
• fresh garlic- for added, savory flavor
• smoked paprika- adds a hint of wood-fired flavor and a touch of warmth without being "spicy-hot."
• dried thyme- it pairs perfectly with white beans and helps round out the savory base of the broth
• dried rosemary- offers a bold, pine-like fragrance and a woody flavor; a little goes a long way in adding a bit of a Mediterranean flair to this hearty soup
• vegetable broth + water- to keep the soup vegan, we use vegetable broth, but low sodium chicken broth also works here  

See recipe card for quantities.

🔪Instructions

Hint: For the best slow-cooked flavor, use the low setting. If you're in a hurry, you can cook it on high for 3 hours instead.

🥣Substitutions

• Great Northern Beans – These are the best direct alternative to cannellini beans. They have a similar creamy texture and mild flavor that holds up well during slow cooking.
• Leeks or Shallots – If you don't have a white onion, leeks or shallots offer a more delicate, gourmet sweetness. They pair beautifully with the earthiness of the rosemary and thyme.
• Liquid Smoke – If you don't have smoked paprika, a tiny drop of liquid smoke can provide that wood-fired "meaty" undertone
• Chicken Broth – While vegetable broth keeps this soup vegan, using low-sodium chicken broth can add a richer, more savory depth if you don't have dietary restrictions.

📖Variations

• Zesty Greens & Lemon – Stir in two cups of fresh spinach or kale and a squeeze of fresh lemon juice during the last 15 minutes of cooking. This adds a bright acidity and a boost of nutrients that lightens up the rich, earthy flavors.
• Hearty Italian Sausage – For those who aren't vegan, brown some ground Italian sausage or sliced kielbasa in a pan before adding it to the slow cooker. The spices from the meat infuse the broth with an extra layer of savory depth.
• Creamy Parmesan – To create a thicker, more indulgent texture, stir in a half-cup of grated Parmesan cheese and a splash of heavy cream (or full-fat coconut milk for a vegan option) right before serving.

See Easy White Bean Chicken Chili for another savory recipe that features beans.

🍽Equipment

• 6 Quart Slow Cooker (Crock-Pot) – lined or greased
• Chef’s Knife and Cutting Board
• Measuring Cups and Spoons
• Colander or Mesh Strainer
• Large Spoon or Ladle
• Skillet (Optional) – Only needed if you choose the "Hearty Italian Sausage" variation to brown the meat before slow cooking.

🍶Storage

Allow the soup to cool completely before transferring it to an airtight container. It will stay fresh in the refrigerator for 3 to 4 days.

This soup freezes beautifully! Store it in freezer-safe bags or containers, leaving about an inch of space at the top for expansion. It can be frozen for up to 3 months.

Thaw frozen soup in the fridge overnight. Reheat on the stovetop over medium heat or in the microwave, stirring occasionally until warmed through. If the soup has thickened too much, add a splash of broth or water to reach your desired consistency.
