Many Names for One Recipe
Anything Mexican food, I’m all in! Those warming spices, rich-saucy flavors and anything I can put an avocado on, all the better. But toss it all in a slow cooker and walk away? You’ve got my attention!
Taco soup is an old favorite, but I didn’t learn until recently that this recipe I’ve been making forever is officially known as taco soup. I had several other names for it like Scott’s bean soup, and Mexican corn and bean sopa. This epiphany came from my Ma, who is a taco soup connoisseur. Little did I know.
A few weeks ago I was getting ready to make this recipe, so I thought I’d ask her about it because she recently said she was making taco soup. I asked her to text me her recipe. Sure enough, I’d been making taco soup all along but of course with my own little twists. The name stuck.
Slow Cooker Vegetarian Taco Soup comes together quick, and then, you can set it and forget it. A long slow cook ensures a rich and thick tomatoey base, concentrated flavors from the spices and tender, creamy beans.
How to Make Slow Cooker Taco Soup
Simple ingredients make up the base of this soup. You’ll need some dry beans. I use three different varieties for color and texture, but you can also use a mix of two if you like.
- First, sort and rinse the dry beans. If using kidney beans, you’ll need to prepare them according to FDAs advisory (see notes**).
- Next, to a crock pot, pour in the dry beans, garlic, onion, fire roasted tomatoes, tomato sauce, corn (frozen, fresh or canned) broth, water, spices and jalapeños.
- Third, cook on low for 7-8 hours or high for 4-5 hours.
- Last, *OPTIONAL* (but recommended): About 15 minutes prior to sharing, make a slurry of masa harina and a bit of water. Stir the slurry into the soup. This will thicken the soup a bit and give it a mildly sweet, corn flavor.
Spoon into bowls and generously pile on your favorite toppings like avocado, onions, cilantro, sour cream, or chili-lime pepita creama, and/or a bit of cheddar.
A Few Recipe Notes
- Time to cook this crock pot taco soup varies depending on bean age, the older the bean the longer the cook. It’s possible that a bean can be so old and dry it won’t cook through. I do not recommend eating under-cooked beans. If they are tough and not showing any signs of progressively getting softer, throw them out. Too, temperature variations range among slow cookers. Be sure to check the manufactures owners manual for guidance on cook times. Use the cook times in this recipe as a guide.
- Soaking the dry beans overnight is optional (except for kidney beans** – see FDAs advisory in notes). If you do soak, the cooking time will be just slightly shorter, but not enough to change the cooking time overall. If soaking the beans overnight, the only adjustment needed is to reduce the broth by about 1/2 C.
- I use fresh jalapeño to add spice and flavor to this recipe. If you like, pickled jalapeño or canned chilis can be used.
- This recipe calls for Masa Harina, but it’s optional. I keep it on hand as a pantry staple to thicken chili and add authentic flavor to my Mexican food. See recipe card for more recipes using masa harina.
- Make this easy Taco Soup vegan by leaving toppings such as sour cream and cheese off.
- Freezer friendly? Yes please!! Freeze in individual lunch portions or in a larger container for up to two weeks.
**UPDATE** : FDAs advisory I’ve been cooking dry beans (including kidney) in a slow cooker for 20+ years without any ill effects but after a reader alerted me to a raw and undercooked kidney bean toxin, I updated this recipe with notes and FDA’s advisory. Feel free to use a mix of black and pinto beans and omit the kidney beans. Just because I’ve not experienced adverse issues, doesn’t mean there’s not the potential for others to experience it. See page 254 on FDA’s Bad Bug Book for more info.

the recipe
Slow Cooker Vegetarian Taco Soup
Ingredients
- 1 1/2 C (320g) Dry Beans (see note about soaking* and FDA cooking advisory on dry kidney beans in the slow cooker**) I use 1/2 C each: pinto, black and/or kidney beans.
- 1 C (125g) Onion purple or yellow, medium dice, about one medium onion
- 2 C (250g) Corn Niblets fresh or frozen
- 1 Tbs Fresh Jalapeño minced, about 1/2 a large jalapeño. Adjust up or down to taste.
- 1 Tbs Fresh Garlic minced, about 3 large cloves
- 1, 15 oz (425g) Can of Tomato Sauce
- 1, 15 oz (411g) Can of Fire Roasted Tomatoes
- 2 Tbs Cumin ground
- 1 1/2 Tbs Chili Powder
- 3/4 tsp Smoky Paprika
- 1/2 tsp Black Pepper
- 2 tsp Fine Sea Salt
- 3 C (675g) Vegetable Broth
- 1 C (225g) Water
- 1 1/2 Tbs Masa Harina (optional - but recommended) mixed with + 1/4 C (56g) water
- For Serving / Garnish: Avocado, jalapeño, cilantro, sour cream, diced onion and/or shredded cheddar
- 1/2 Lime
Instructions
- Pick through the beans picking out any shriveled beans or small stones. Rinse the dry beans and place them in the cook-pot of a slow cooker. If using dry kidney beans, soak/boil them according to FDA's guidelines below in the notes (and make sure they're fully cooked) before adding them to the soup or use one can (drained) of already cooked kidney beans. Add them to the crock during the last 30 minutes of cooking. To the beans add the onion, corn, jalapeño, garlic, tomato sauce, tomatoes, cumin, chili powder, paprika, black pepper, salt, broth and water. Stir throughly.
- Set the slow cooker on high or low. Total Time: Low Setting = 7-8 hours | High Setting = 4-5 hours. The total cook time will depend on how fresh the dry beans are. The fresher the beans, the less time, the older (more dry), the longer the cook time. Keep an eye on the beans as they near the low end of the cook time and add more water if needed. The beans are done when they give under gentle bite pressure and are creamy on the inside. It’s possible that a bean can be so old and dry it won’t cook through. I do not recommend eating under-cooked beans. If they are tough and not showing any signs of progressively getting softer, throw them out. Also, depending on the crock pot used, these cook times will probably vary. Temperature variations range among slow cookers. Use the cook times in this recipe as a guide. Be sure to check the manufactures owners manual for guidance on cook times.
- (OPTIONAL): About 15 minutes before serving, mix the Masa Harina with hot water and pour into the soup. Stir. The soup will begin to thicken during the last minutes of cooking. One maker, Sabrina, added a good squeeze of lime at the end of cooking - I agree!
- Ladle into soup bowls and garnish with any toppings you like: avocado, jalapeño, cilantro, sour cream, diced onions, lime wedges or shredded cheddar.
- Store in the refrigerator in a lidded container for up to three days or freeze for up to two weeks. Thaw overnight in the fridge and gently rewarm on low heat on the stovetop.
Hi. Any way this could be done on the stove. I no longer have a slow cooker. Thanks
I made it on the stove and used canned beans. Turned out great.
Hi Katie! Thank you for your note and tip! So happy to hear you enjoyed it.
Hmm… what’s the difference between this Mexican ‘Soup’ and vegetarian chili? Looks thick and hearty to me – very similar to my favorite chili recipe.
Similar yes, but the main differences, when compared to my vegetarian chili recipe (and I realize chili recipes run the gamut) is that this Taco Soup has tomato sauce and corn in it, where as my chili recipe does not.
I’ve always read that beans will not cook after adding any tomato sauce or like mixture.
So, I want to confirm, that you add all of these ingredients to your crockpot and the beans cook very well. ??
Hi LouAnn! That’s not been my experience with beans and tomatoes. I hope this helps!
The flavor of this is absolutely delicious but my beans are not soft enough even after having this in the crockpot all day. I looked the issue up and learned some things about beans. Apparently they can be pretty toxic if not cooked all the way. I saw warnings about not relying on a crockpot to cook dry beans. I also saw several mentions that acids (like tomatoes) should not be added until beans are cooked because it inhibits the cooking process. I’m not sure what to do now and I’m afraid I may have to throw the whole thing out. The beans are just not getting soft and I don’t know if continuing to cook them in crockpot will help. Unfortunately I ate a bowl before I did the research and now I’m worried I’ll get sick. I don’t think I’ll use dry beans in a crockpot again. The flavor is good though. 🤷🏻♀️
P.S. my stomach is now starting to hurt 😞
Hi Katie. Thank you for your note and letting me know about the FDA’s advisory on kidney beans! I’ve added their resource and advisory in the post/recipe. I’ve been cooking dry beans (including kidney) in the crock pot for over 20 years (until the beans are soft and creamy) and haven’t experienced any ill effects. But I appreciate your letting me know so I can share the information in this space. I’m sorry to hear your beans didn’t cook through. Sometimes this is a result of old beans. I hope you’re feeling better.
I liked the addition of the masa harina! I’ve had a bag just sitting on my shelf after a failed attempt to make tamales. Overall, I enjoyed this recipe. I made it on the stove, but cooked the beans in the instant pot after soaking about 6 hours (didn’t have time to soak longer). I used 1.5-2x the amount of spices and added in chopped red pepper. This could have benefitted from a squeeze of lime.
Hi Sabrina! Thank you for your notes. So happy you enjoyed the recipe and adapted it to your taste/needs! Thank you for your note on the squeeze of lime! I don’t know why I left that off?! Mexican food always benefits from it!
Love this recipe! It is super hearty. It has the perfect blend of spices.
Thank you!
Hi Christina! Thank you so much for coming back and leaving a note! I’m so happy to hear you’re enjoying the soup! :D
We made your taco soup last night to serve for National Margarita Day – awesome recipe! We used whole milk greek yogurt instead of sour cream to garnish.
Hi Monica! Thank you for coming back and leaving a note – and hooray for National Margarita Day! I didn’t know (and how?!). SO happy to hear y’all enjoyed the recipe! And thank you for your tip on whole milk greek yogurt! Delicious!
I’m all in for Mexican flavors too, Traci! This taco soup looks fabulous :)
Isn’t it funny about naming recipes, Traci? Taco soup sounds delicious to me. Love how easy and flavorful this is! Lots of healthy ingredients and spicy flavor – perfect for this time of year and good for you too! Looking forward to trying this! Have a great weekend. Xo
Hi
Looks amazing, like all your recipes.
I am wondering about NOT soaking the beans though. For people with sensitive tummies, would this be an issue, or because its done in liquid for so long, should be ok??Just wondering about thoughts on this soaking vs not. or maybe I could soak and don’t put in crockpot for as long, but would be tricky I think getting them perfectly cooked.
Hi Leanne, thank you for your note and kind words! Not soaking could be an issue for some, but I’ve not experienced this in our household (and this could be because we eat a lot of beans?). The reading I’ve done seems to point to individual preference and/or dietary needs. I’m sure there’s more to this that I don’t know, so please do what best suits your family’s needs. I do typically soak when I’m cooking on stovetop (ie. faster) because it produces a more tender bean. But when cooking in the crock pot, I’ve not noticed a difference. If you do soak and cook in the crock pot *and are able keep an eye on them until done, please share with us about how long you cooked them for. Thank you! I hope this helps and you enjoy the recipe!
My first thought as I was clicking on this recipe was Mexican, I’m all in, and then I cracked up as I read your first line! You must be in serious need of warming, slow cooked comfort food like this with all of the snow you’ve been socked with. Hope you are doing ok and managing to enjoy the beauty of it all.
Love how easy this is! And that trick with the masa – must try! Have a fabulous weekend, Traci!
I am confused why you would cook for less time on low setting? It seems like the high and low times are swapped???
Hi Jen! You’re right! Oops! Thank you for catching that. It’s fixed!
I’m always looking for new slow cooker recipes Traci and this is one I will gladly add to my list! I’m all in when it comes to anything taco and so is Tom! Love the combination of beans you used and great idea to use the masa harina to thicken it up and give it that extra flavor. Can’t wait to try this one! Happy weekend! Mary Ann
