I first started making this Slow Cooker Taco Soup during a stretch of long days when I needed something hearty but didn’t want to juggle a dozen ingredients. Taco night is always a win in my house, and soup night is even easier — so combining the two just made sense. One pot, bold flavors, and that comforting smell filling the house all afternoon.

What I love most is how forgiving this recipe is. It’s perfect for busy weekdays, game days, or anytime you want something warm and filling without babysitting the stove. By dinner, you’ve got a rich, taco-flavored soup that tastes like it took way more effort than it did. Add a handful of toppings, and suddenly it feels like a fun, build-your-own meal.

This soup has become a staple in my kitchen because it checks every box: it’s budget-friendly, pantry-stable, endlessly customizable, and absolutely delicious. The ground beef makes it hearty enough to be a main course. The taco seasoning brings all those familiar, bold flavors. And the beans, corn, and tomatoes create a satisfying, chunky texture that everyone loves.

Whether you’re feeding a crowd on game day, meal-prepping for the week, or just need a no-fuss dinner on a busy Tuesday, this taco soup delivers.

Ingredients

Ground beef – 1 pound, browned and drained
Taco seasoning – 1 packet (about 1 ounce)
Diced tomatoes – 1 can (15 ounces), with juices
Black beans – 1 can (15 ounces), drained and rinsed
Corn – 1 can (15 ounces), drained
Beef broth – 2 cups

Ingredient Notes

What kind of ground beef?80/20 (80% lean, 20% fat) is ideal for flavor. Drain the excess grease after browning. You can use leaner beef (90/10 or 93/7) — you may not need to drain anything.

What kind of taco seasoning?Any standard 1-ounce packet works. Mild, original, or spicy — choose based on your heat preference. You can also use 2–3 tablespoons of homemade taco seasoning (chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and pepper).

Can I use fresh or frozen corn instead of canned? Absolutely. Use 1½ cups of fresh or frozen corn kernels. No need to thaw if using frozen.

What kind of diced tomatoes?Regular, fire-roasted, or tomatoes with green chiles (like Rotel) — all work beautifully. Fire-roasted adds a subtle smoky depth. Rotel adds a little heat.

Why drain and rinse the beans?Draining and rinsing removes the thick, starchy liquid from the can, which can make the soup gummy. It also reduces the sodium content.

Can I use chicken broth instead of beef broth? Yes. Chicken broth is slightly lighter but works perfectly. Vegetable broth works for a vegetarian version (omit the beef or use plant-based crumbles).

Step-by-Step Instructions

Step 1: Brown the Ground Beef

In a skillet over medium-high heat, brown the 1 pound of ground beef until fully cooked, breaking it into small crumbles with a spatula. This takes about 5–7 minutes.

Drain the excess grease from the cooked beef.

Step 2: Add Everything to the Slow Cooker

Transfer the browned and drained ground beef to your slow cooker.

Add:

1 packet taco seasoning
1 can (15 oz) diced tomatoes (with juices)
1 can (15 oz) black beans, drained and rinsed
1 can (15 oz) corn, drained
2 cups beef broth

Stir everything together until well combined.

Step 3: Cover and Cook

Cover the slow cooker with the lid. Cook on:

LOW for 6 to 7 hours, or
HIGH for 3 to 4 hours

The soup is ready when it’s hot, bubbly, and the flavors have melded together beautifully. Because everything is already cooked (the beef is browned, the canned goods are pre-cooked), you’re really just heating everything through and letting the flavors marry.

Step 4: Stir and Serve

Stir the soup well before serving. Taste and adjust seasoning if needed — add more salt, pepper, or a pinch of chili powder if you like.

Ladle into bowls and let everyone add their favorite toppings.

Variations & Tips

Make It Spicier

Use hot taco seasoning
Add 1 can (4 oz) of diced green chiles
Stir in 1 teaspoon of cayenne pepperor red pepper flakes
Use Rotel tomatoes with habanero(if you can find them)
Top with sliced fresh jalapeños or pickled jalapeños

Make It Milder

Use mild taco seasoning
Omit any spicy additions
Serve with plenty of sour cream and cheese (dairy helps tame the heat)
Add a dollop of plain Greek yogurt to each bowl

Add More Vegetables

Stir in any of these during the last 30 minutes of cooking:

1 bell pepper, diced (adds color and crunch)
1 zucchini, diced (adds bulk without strong flavor)
1 cup frozen peas or green beans
1 cup sliced mushrooms

Make It Thicker

Mash some of the beansagainst the side of the slow cooker before serving. The mashed beans will thicken the soup naturally.
Make a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water) and stir in during the last 20 minutes on HIGH.
Add a can of refried beans(stir in well — it will thicken the soup significantly and add a creamy texture).

Make It Creamy

Stir in ½ cup of cream cheese(cut into cubes) or ½ cup of sour cream during the last 30 minutes of cooking. The soup will become rich, creamy, and almost stew-like.

Make It with Turkey or Chicken

Substitute 1 pound of ground turkey or 1 pound of shredded cooked chickenfor the ground beef. For ground turkey, brown it just like beef. For shredded chicken, add it already cooked during the last hour.

Make It Vegetarian

Omit the ground beef
Add 1 additional can of beans(kidney beans, pinto beans, or more black beans)
Use vegetable broth instead of beef broth
Add 1 cup of frozen corn for extra bulk

Make It in an Instant Pot

Use the “Sauté” setting to brown the ground beef directly in the Instant Pot.
Drain the grease.
Add all remaining ingredients.
Pressure cook on HIGH for 10 minutes.
Natural release for 5 minutes, then quick release.

Storage & Reheating

Refrigerator: Store leftovers in an airtight container for up to 5 days. The flavors will deepen and improve overnight — this soup is famously better the next day.

Reheating:

Microwave: 1–2 minutes per serving.
Stovetop: Warm over medium heat, stirring occasionally. Add a splash of broth or water if it’s too thick.
Slow cooker: Warm on LOW for 30–45 minutes.

Freezing: This soup freezes beautifully for up to 3 months. The beans and corn hold up well, and the beef doesn’t become grainy. Freeze in individual portions for easy lunches. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions (FAQs)

Can I use dried beans instead of canned?

Yes, but you’ll need to cook them first. Dried black beans must be soaked and cooked before adding to the slow cooker (raw dried beans contain toxins that must be destroyed by boiling). For convenience, canned beans are highly recommended for this recipe.

Can I make this without browning the beef first?

Technically yes, but you’ll lose a lot of flavor. Browning the beef creates the Maillard reaction — those browned, caramelized bits that add deep, savory flavor to the soup. It only takes 5 minutes and is absolutely worth it.

Why is my soup thin?

This soup is meant to be brothy, not thick like chili. If you want a thicker soup:

Mash some of the beans
Add a cornstarch slurry
Use less broth (1½ cups instead of 2)
Let it simmer uncovered for the last 30 minutes to reduce

Can I use fresh tomatoes instead of canned?

Yes. Use about 1½ cups of diced fresh tomatoes. You may need to add a little extra liquid (tomatoes release water as they cook, so start with 1½ cups of broth and add more if needed).

Can I double this recipe?

Yes. Use a larger slow cooker (7–8 quarts). Double all ingredients. Cooking time remains the same. Do not fill the slow cooker more than ¾ full.

What if I don’t have taco seasoning?

Make your own! Combine:

1 tablespoon chili powder
1 teaspoon ground cumin
1 teaspoon paprika
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon dried oregano
½ teaspoon salt
¼ teaspoon black pepper

Toppings Bar (The Best Part!)

Set out a variety of toppings and let everyone build their own bowl. This is what makes taco soup so fun.

Essential toppings:

Shredded cheddar cheese – Sharp or mild
Sour cream – A dollop cools the heat and adds creaminess
Tortilla chips – Crushed on top for crunch
Sliced green onions – Fresh and mild

Next-level toppings:

Fresh cilantro – Chopped
Diced avocado or guacamole – Creamy and rich
Sliced black olives – Salty and briny
Pickled jalapeños – For heat and tang
Hot sauce – Let everyone choose their own heat level
Lime wedges – A squeeze of fresh lime brightens everything

What to Serve With It

This soup is a complete meal on its own, but here are some pairing ideas:

On the side:

Cornbread – Sweet, crumbly, and perfect for dipping
Cheese quesadillas – Cut into strips for dipping
Mexican rice – Serve on the side or stir into the soup
Simple green salad – With lime vinaigrette

For dipping:

Tortilla chips – The classic
Saltine crackers – Surprisingly good
Fritos – Adds corn flavor and crunch

Why This Recipe Works

This taco soup is greater than the sum of its parts. Here’s why:

Ground beef provides hearty, savory depth. Taco seasoningbrings all the familiar, craveable flavors of taco night. Diced tomatoes add acidity and brightness. Black beans add protein, fiber, and a creamy texture. Corn adds sweetness and pop of color. Beef brothties everything together into a rich, savory base.

The slow cooker allows these flavors to meld slowly over hours, creating a soup that tastes complex and developed — even though you barely lifted a finger.
