Air Fryer White Bean Soup is my go-to when I want something hearty and comforting that doesn't require much effort. It's a flavorful soup made with cannellini beans, tender vegetables, fresh spinach, and finished with lemon and Parmesan for brightness and richness. I love it for fall and winter dinners, Meatless Mondays, or anytime I'm craving something warm and nourishing. It's filling but not heavy, budget-friendly, and comes together quickly in the air fryer. Store leftovers in the fridge for up to 4 days or freeze for up to 3 months.
In an oven dish, combine oil, onion, carrots, and celery, and bake in the air fryer at 350°F (180ºC) for 7 minutes until tender. Add garlic and cook for 1 more minute.
Then, add beans, broth, parsley, thyme, salt, and pepper. Cook again for another 15 minutes.

Next, add spinach and cook for 10 minutes more. Stir in fresh lemon juice and Parmesan cheese. Taste and adjust seasoning with salt and pepper if needed.
Serve in bowls, garnished with parsley and crusty bread.

Notes
Here are my best tips for making Air Fryer White Bean Soup perfectly every time:
Use an oven-safe dish: Make sure your dish fits comfortably in the air fryer basket with at least an inch of clearance on all sides so air can circulate properly.
Don't skip rinsing the beans: Draining and rinsing canned cannellini beans removes excess sodium and the starchy liquid that can make the soup too thick or gummy.
Stir halfway through: When the beans and broth are cooking for 15 minutes, stir once at the 7-minute mark so everything cooks evenly and nothing sticks to the bottom.
Adjust thickness to your liking: If the soup gets too thick, just stir in extra vegetable broth or water a little at a time until it reaches your preferred consistency.
Add lemon at the end: Fresh lemon juice loses its brightness if cooked too long, so stir it in after the soup finishes cooking for the best fresh, citrusy flavor.
Flash freeze for easy portions: Freeze individual servings in muffin tins for about 2 hours, then pop them out and store in a freezer bag so you can grab just one or two portions whenever you need them.
