Perfect for Meal Prep & Leftovers
This soup is ideal for meal prep, as it reheats beautifully and the flavors deepen over time. Make a big batch on the weekend and portion it into containers for easy lunches or quick dinners throughout the week.
You can also freeze it for later, ensuring a delicious homemade meal is always within reach. The hearty beans and sausage keep you full, while the spinach adds a touch of freshness even after reheating.
Customizing This 15-Bean Soup
One of the best things about this one pot recipe is its versatility. Here are a few ideas for tailoring it to your preferences:
- Make it vegetarian: Swap out the sausage for plant-based alternatives or additional vegetables like zucchini or sweet potatoes.
- Boost the spice: Add more red pepper flakes or a splash of hot sauce for extra heat.
- Go gluten-free: Use gluten-free chicken broth and double-check your sausage for hidden gluten.
- Try different greens: If spinach isn’t your favorite, kale or Swiss chard are great substitutes.
Tips for the Best Slow-Cooked Soup
To ensure your soup turns out perfectly every time, keep these tips in mind:
- Rinse the beans: Discard the seasoning packet and rinse the beans thoroughly to remove excess starch and improve texture.
- Layer flavors: Sauté the sausage, onion, and garlic before adding them to the slow cooker to build a deep, rich flavor base.
- Cook low and slow: If you have the time, opt for the low setting on your slow cooker. It allows the beans to soften and absorb all the savory flavors.
Pairing Suggestions for a Complete Meal
While this soup is satisfying on its own, pairing it with a side can elevate your dining experience. Serve it with:
- Crusty bread: Perfect for soaking up the flavorful broth.
- Simple salad: A crisp side salad with a light vinaigrette complements the hearty soup.
- Roasted vegetables: Add even more depth to your meal with roasted carrots, parsnips, or brussels sprouts.
Whether you’re cooking for a family dinner, prepping meals for the week, or simply craving comfort food, this one pot recipe is a must-try!
