STORAGE & FREEZING : Slow Cooker Navy Bean Soup
Store cooled soup in airtight containers in the fridge for up to 4 days. For meal prep, divide into single-serve containers. This makes it easy to reheat and control portions. For longer storage, freeze soup in freezer-safe containers or heavy freezer bags for up to 3 months. Thaw in the fridge overnight before reheating.
To reheat, warm gently on the stovetop over low heat, stirring often. If the soup is thick after cooling, add a splash of water or broth to reach your preferred texture.
SERVING SUGGESTIONS
Balanced side options:
- Large green salad with vinegar dressing (keeps meal light and low calorie).
- Steamed broccoli or green beans for extra fiber.
- Small serving of brown rice or quinoa if you need extra carbs for activity.
For a lighter option, pair one cup of soup with a big mixed salad and skip the roll. For a more filling meal, add a side of roasted lean chicken breast or a boiled egg to boost protein.
VARIATIONS
-
Healthier version:
Reduce the olive oil to 1 tablespoon or omit it. Lower salt to 3/4 teaspoon and use low-sodium broth instead of water if you want a deeper flavor without added salt. Add extra vegetables like zucchini or spinach for more fiber and micronutrients. -
High-protein or low-carb version:
For a high protein meal, add 2 cups of shredded cooked chicken breast or diced turkey in the last 30 minutes of cooking. You can also stir in canned tuna (drained) at the end. For a low-carb friendly bowl, reduce the beans to 1 cup and add 2 cups of chopped cooked chicken or firm tofu. This keeps the soup satisfying while cutting net carbs. Note that lowering beans reduces fiber; balance with leafy greens. -
Air fryer or oven-baked version:
Use the air fryer to roast the diced fennel, carrots, and onion first. Toss them with a little olive oil, salt, and pepper, then air fry at 375°F for 12–15 minutes until caramelized. Add the roasted vegetables to a pot with beans and water and simmer on the stove for 1–2 hours until beans are tender. Or use a Dutch oven and finish the soup in a 350°F oven for 1 hour for a slow, even simmer. For a crunchy topping, make bread cubes in the air fryer to serve as croutons.
