This 3 Ingredient 15 Bean Soup with Sausage is hearty, delicious, and incredibly easy to make. Just like my 4 Ingredient Cheater Lasagna, the secret is in using flavorful ingredients. Starting with these types of products from the grocery store gets you a crazy delicious and filling soup you can make any time.

Add a side of crusty buttered bread or even better, a slice of warm cornbread, and you’ll have tummies filled and satisfied.

What’s So Lovely About This 3 Ingredient Soup

  • Well, because it’s only 3 main ingredients. The beans come from a bean soup package so they’re counted as one ingredient.
  • It’s made in a crockpot, so it’s basically throwing it all together (set it and forget it) until dinner.
  • Low cost and easy is the game with this one. Minimal ingredients, under 10 bucks, and it feeds an army!

Groceries Needed

Raw sausage, a can of diced tomatoes and a package of 15 bean soup mix on a marble table.
Three ingredients used to make this soup is sausage, diced seasoned tomatoes, and a 15-bean soup pack.
  • Dry Bean Soup Mix: I used Hurst’s brand Hambeens 15 Bean Soup Mix. It’s inexpensive and comes with a seasoning packet. If you can’t find Hambeens, there are other brands that have a variety of beans all in one bag, so use what you can find available. All the beans they collect in the package will make a fantastic soup, so don’t worry if the mix will taste great or not. *Note: Sometimes other brands don’t come with a seasoning packet which I found out the hard way. Look in the recipe card below for suggestions if this happens to you.
  • Italian Sausage: Use your favorite brand. I used a spicy Italian sausage for even more flavor, but if you’re worried about the heat, use a regular or “sweet” Italian sausage. If the sausage you find is only in link form, simply remove the meat from the casing and then proceed with the recipe.
  • Canned Diced Tomatoes: Choose a brand that has added seasonings to it. The one I chose had added garlic, oregano, and basil. If you can’t find anything like that, try choosing ‘fire-roasted diced tomatoes. The fire-roasting char on the tomatoes will add extra flavor when combined with this 15-bean soup recipe with sausage.

Eazy Tip: Remember, salt, pepper, garlic, oil and water don’t factor into the ingredient count because most people have those pantry items in their kitchen.

Directions for Making this Hearty Slow Cooker Soup

Honestly, this is so super easy, check it out.

  1. Brown the sausage. (This step is optional but recommend you do it. It adds nice color to the meat so it doesn’t look anemic in the soup, plus the caramelization (called the Maillard reaction) also adds extra flavor to the soup that comes for free!
  2. When finished browning, add the sausage to the crockpot, along with the beans and seasoning packet, and the can of tomatoes. (Don’t drain the tomatoes! Add that extra flavor to your delicious soup.)
  3. Add the water, give it a good mix, put the lid on it, set it, and go about your day till it’s ready to serve!

Full instructions are listed in the printable recipe card at the bottom of this post.

Variations For This Crockpot Bean Soup

  • Try swapping out the water for chicken or vegetable broth if you have it on hand.
  • Add a cup of rice or small pasta shapes (macaroni, ditalini, etc) in the last 30 minutes before serving to stretch the volume of the soup even more. You may want to add another cup of water or broth.
  • Adding a few cups of frozen diced vegetables (carrots, corn, and peas) will give more nutrition to the soup, more flavor, and more volume to feed more people.
  • Serve with some rolls, bread, or some easy-to-make cornbread if you don’t have a box of Jiffy on hand.
  • Switch out the sausage with smoked kielbasa to make a delicious fifteen-bean soup with smoked garlic sausage.

Storing Leftovers

Eazy Peazy!

Fridge: Place the soup in a container with a lid or place plastic wrap over the top. Store in the fridge for up to 5 days.

Freezer: This bean soup freezes like a charm. Transfer leftovers into a freezer-friendly container and freeze for up to 3 months.
To thaw, put it in the fridge overnight, or thaw it in the microwave in a glass container.

Can I use canned beans instead?

Absolutely. Some producers make a 6-bean or a 3-bean combination in cans. If you can’t find that, try using Great Northern Beans, Red Kidney Beans, Cannellini Beans, and even black beans if you like. You won’t have the variety that the 15-bean combination offers, but it will still be delicious.

Can I use beef broth instead of chicken broth?

Yes. It may have a slightly different flavor profile than using chicken broth, but I’m sure it won’t even be noticeable with all the other flavors coming together.

Can I start with frozen sausage?

I recommend you don’t for a few reasons. Safety in how long it takes for the sausage to thaw and then come up to temp in the slow cooker, and also being able to cook the sausage beforehand – you don’t want to miss out on adding that extra flavor!

3 Ingredient 15 Bean Soup with Sausage

Slow cooker bean soup in a white bowl that's sitting on a black tray.

A delicious and super hearty soup to make. 15 bean soup with sausage will easily become a staple meal in the house simply because it's easy, nutritious and delicious!

Prep Time 5 minutes
Cook Time 6 hours
Total Time 6 hours 5 minutes


  • 1 package of 15 Bean Soup, dry mix (20 ounces)
  • 1 can Diced Tomatoes with spices, 14.5 ounces, undrained
  • 1 pound Italian sausage, either hot or sweet (regular)
  • 10 cups water
  • Salt and pepper as desired.


  1. *Optional Step, but recommended*. Place the sausage into a skillet and brown it completely before adding it to the slow cooker.
  2. Rinse the beans under cool water. Add them along with the browned sausage and can of tomatoes to the slow cooker.
  3. If there is a seasoning packet in the package of beans, put that aside and use it for another dish. The seasoning that comes from the sausage and the tomatoes is enough to flavor this delicious soup.
  4. Put the lid on the slow cooker and cook on low for 7-8 hours or high for 5-6. You know the soup is ready when the beans are tender, but not mushy.
  5. Season with salt and pepper before serving. Enjoy!


Salt and pepper, garlic, oil and water are not counted as ingredients as most people have these items in their kitchen already.

Frying the sausage first allows a sear (or caramelization) on the sausage that adds flavor. Also, it helps adds color to the meat so it doesn't look a funny grey color.

If your soup packet didn't come with a seasoning pouch, then feel free to use things like seasoning salt, garlic powder, onion powder, sage, dried chilis, dried rosemary, a touch of fennel seed, etc. If you would like to season things in an easier way, try using Montreal Steak Spice. I find it to be a really tasty all-around seasoning.
