- 1 (15 oz) can kidney beans, drained and rinsed
- 1 (15 oz) can cannellini beans, drained and rinsed
- 1 cup green beans, trimmed and cut into 1-inch pieces
- 1 cup small pasta (e.g., ditalini, elbow, or gluten-free pasta)
- 1 tsp dried oregano
- 1 tsp dried basil
- 1 bay leaf
- 1 tsp salt (adjust to taste)
- ½ tsp black pepper
- 2 cups fresh spinach or kale, chopped
- 2 tbsp olive oil
- Fresh parsley or basil for garnish (optional)
- Vegan Parmesan cheese for serving (optional)
Optional Add-Ins for Extra Flavor
- 1 tsp smoked paprika (for depth)

Step-by-Step Instructions
1. Prep Your Ingredients
Chop all vegetables into uniform pieces to ensure even cooking. If using dried beans, soak them overnight or use canned beans for convenience. Measure out your spices and have your slow cooker ready.
2. Sauté the Aromatics (Optional but Recommended)
For deeper flavor, sauté the onion, garlic, carrots, and celery in olive oil in a skillet over medium heat for 5 minutes until softened. Transfer to the slow cooker. Skip this step if you’re short on time—it’ll still taste great!
3. Add Everything to the Slow Cooker
Combine the sautéed veggies (or raw veggies if skipping the sauté step) with the remaining ingredients except the pasta, spinach/kale, and fresh herbs. Stir well to combine.
4. Cook on Low or High
- Low: Cook for 6–7 hours for maximum flavor development.
- High: Cook for 3–4 hours if you’re in a hurry.
5. Add the Final Touches
30 minutes before serving, stir in the pasta and spinach/kale. If the soup is too thick, add a splash of vegetable broth. Taste and adjust seasoning with more salt or pepper if needed.
6. Serve and Enjoy!
Ladle the soup into bowls and garnish with fresh parsley or basil, vegan Parmesan, and a drizzle of olive oil. Serve with crusty bread or a side salad for a complete meal.
Pro Tips for the Best Vegan Minestrone Soup
1. Don’t Overcook the Pasta
Add the pasta toward the end of cooking to prevent it from turning mushy. If meal prepping, store the pasta separately and add it when reheating.
2. Use Homemade Vegetable Broth
For richer flavor, use homemade vegetable broth instead of store-bought. Save veggie scraps (carrot tops, celery leaves, onion skins) in the freezer to make your own.
3. Make It Gluten-Free
Swap regular pasta for gluten-free pasta or omit it entirely. Use quinoa, farro, or rice for a grain-based alternative.
4. Freeze for Later
This soup freezes beautifully! Store in airtight containers for up to 3 months. Freeze without pasta to avoid mushiness—add fresh pasta when reheating.
5. Boost the Protein
Add 1 cup of cooked lentils or ½ block of crumbled tofu for extra plant-based protein. Chickpeas also work well as a bean substitute.
6. Add Umami Flavor
Enhance the depth of flavor with 1 tbsp of nutritional yeast, 1 tsp of soy sauce, or a Parmesan rind (remove before serving).
Delicious Variations to Try
One of the best things about minestrone is its adaptability. Here are some creative twists:
1. Creamy Minestrone
Stir in ½ cup of coconut milk or cashew cream at the end for a rich, creamy texture.
2. White Bean Minestrone
Swap kidney beans for great northern beans or butter beans for a milder flavor.
3. Summer Minestrone
Use seasonal summer veggies like corn, cherry tomatoes, and fresh basil. Add a squeeze of lemon juice for brightness.
4. Winter Minestrone
Incorporate hearty winter veggies like butternut squash, sweet potatoes, or kale. Add a pinch of cinnamon or nutmeg for warmth.
5. Italian-Inspired Minestrone
Add 1 tbsp of tomato paste and ½ cup of red wine when sautéing the aromatics for a deeper, more complex flavor.
