Ingredients for slow cooker taco soup

  • Ground beef – Ground beef is packed with protein and is extra delicious in this soup.
  • Taco seasoning – Feel free to use your favorite homemade or store-bought variety.
  • Rotel – Rotel is a mix of canned tomatoes, chiles, and spices that will add moisture and flavor to the soup. 
  • Diced green chiles – Diced green chiles will add a slightly spicy kick to our soup.
  • Beans – I’ve used a combination of black and kidney beans here, but if you prefer one over the other, feel free to use your favorite.
  • Fire roasted tomatoes – These fire-roasted diced tomatoes will add a hint of smokiness to our soup.
  • Yellow onion – A classic ingredient that will add earthiness and sweetness.
  • Ranch seasoning – Feel free to use your favorite homemade or store-bought variety.
  • Lime juice – Fresh is best! The lime juice will add brightness and freshness to the soup when it’s served.

Making your own taco seasoning

Most store-bought taco seasonings are perfectly fine, but if you prefer to have control over the ingredients (whether it be to monitor levels of spice, or avoid certain allergies,) it’s super simple to make your own taco seasoning at home!

My favorite blend is 1 tbsp of chili powder, 1 tsp of cumin, garlic powder, onion powder, and paprika, ½ tsp of oregano, black pepper, and red pepper flakes.

This is a fairly mild blend, and not too spicy. 

You’ll see I’ve left out salt, and that’s on purpose. I like to control the amount of salt separately in the dish. 

Feel free to add other spices like ground chipotle powder, or smoked paprika, or more or less crushed red pepper flakes as you see fit. 

Fun toppings

Making a little toppings bar ahead of time is a great way to get guests to interact when you’re having a party!

Some of my favorite topping offerings are: sour cream (or Mexican crema,) diced white onions, cilantro, shredded cheddar cheese, sliced avocado, corn chips, or sliced jalapeños. 

You can prepare the little bowls of toppings the day before, and keep them covered with plastic wrap in the refrigerator. 

When you’re ready to serve the soup, just bring out the bowls and uncover them for your guests to go wild!

Storage and leftovers

Any leftovers can be kept in an airtight container in the refrigerator for up to 4 days.

To reheat, simply place in a microwave-safe bowl and cover loosely with a paper towel, and heat for 3-4 minutes or until heated thoroughly.
