Easy 40-Minute Vegan Mexican Bean Soup with Toppings

Chilies (like this vegan bean chili) and other bean-based recipes, like this Mexican bean soup and this Mexican inspired vegetable soup, are some of our favorites: They’re usually inexpensive to make, hearty, and packed with nutrients – and this is no different. With a combination of nutritious vegetables (like bell pepper and corn) and fiber and protein-rich beans, this recipe could be called Mexican bean soup, vegan tortilla soup, and meat-free Southwest soup—oh, and delicious!

By using tinned beans and tomatoes with fresh or frozen inexpensive vegetables, this soup is a quick, low-cost midweek meal ready in just 30 minutes with very little hands-on time required and just one pot. It’s perfect for busy weeknights as a crowd-pleasing, comfort food lunch or dinner to keep you satisfied for hours.

Plus, you can cook it with one of three methods: stove, crockpot, or Instant Pot. With minimal chopping needed, sauté the veggies, throw in the rest of the ingredients, and leave it to simmer, hands off, to allow the flavors to meld with a satisfying depth of flavor. It’s really easy to customize seasoning and spice levels, too, and add your favorite toppings like avocado, tortilla chips, and hot sauce.

Best of all, this delicious vegetarian Southwestern soup tastes even better on day two and is both meal-prep and freezer-friendly, just like our hearty kale & bean soup, barley and bean soup, quick mole soup, and black bean chili!

How to Make Mexican Bean Soup

Let it simmer even longer for a more developed flavor, adding a little extra water/broth if needed. You can also taste and salt to season.

Slow Cooker Mexican Bean Soup

Making this bean-based vegan tortilla soup in a crockpot is a great set-and-forget meal for busy weekdays.

1. First, prepare the vegetables.
2. Then, throw everything into the crock pot, mix thoroughly, and cook over LOW for 4-6 hours or HIGH for 1-2 hours, stirring. Add more broth/water if needed. Then try it and adjust salt/cumin to taste, garnish, and enjoy!

Instant Pot Vegan Southwest Soup

1. First, prepare the vegetables.
2. Use the sauté function to cook the onion, bell pepper, and garlic until tender.
3. Add the remaining ingredients and cook on manual HIGH pressure for 5 minutes.
4. Carefully set the pressure release valve to the ‘venting’ position to release the remaining steam. Enjoy!

Top Recipe Tips and Notes

• Cut veggies evenly: So they cook evenly within the black bean corn soup.
• For a creamier consistency: Use an immersion blender directly in the crockpot or transfer a small amount of the beans and broth to a blender to blend until creamy, then mix it back into the soup.  
• To adjust the consistency: Add more broth for a thinner, brothier vegan chili soup.
• Temper the spice/s: For more flavor, add the cumin when sautéing the veg to help temper the spices for a better flavor.

Topping Ideas

Like chili, this Mexican bean soup is made even better with all your favorite toppings. We like to use avocado, hot sauce, and tortilla chips, but you could also add:

• Fresh herbs (parsley, cilantro, scallions)
• Jalapeno slices
• Grilled corn
• Fresh salsa, like easy Pico de Gallo
• Vegan sour cream or dairy-free yogurt
• Radish slices
• Tofu feta cheese
• Lime wedges

Storage Instructions

Allow the Southwest black bean soup to cool, then store the leftovers in an airtight container in the fridge for 3-4 days (it tastes even better on day two!). Alternatively, freeze it for up to 3 months. Then, leave it to thaw in the refrigerator overnight before reheating it.

We like to reheat the soup gently on the stovetop or in the microwave (in 30-second increments, stirring in between) until piping hot. If it’s thickened, add water or vegetable broth.
