Ingredients Overview

This soup uses pantry staples and common Tex-Mex flavors to create a dish that’s easy, filling, and budget-friendly.

Ground Beef

• 80/20 ground beef offers great flavor and richness.

• For a leaner version, choose 90/10 beef, or substitute ground turkey or ground chicken.

• For a vegetarian option, skip the meat or use a plant-based ground alternative.

Onion & Garlic

• Provide aromatic depth and a base layer of flavor.

• Yellow or white onions work well. Garlic adds savory warmth.

Canned Diced Tomatoes

• Use fire-roasted for a smoky layer.

• Regular or petite diced tomatoes work too.

Rotel (Diced Tomatoes with Green Chilies)

• Brings a mild heat and tangy kick. Adjust based on your spice preference.

Beans

• Black beans and pinto beans are classic for Tex-Mex soups.

• Use canned, drained, and rinsed for convenience.

• Kidney beans or white beans can be used for variety.

Corn

• Adds sweetness and texture.

• Fresh, frozen, or canned corn all work — no need to thaw frozen.

Taco Seasoning

• Use homemade or store-bought taco seasoning to season the entire pot.

• Add more or less depending on how bold you like it.

Ranch Dressing Mix (Dry)

• A surprise flavor-booster often used in taco soup. Adds tang and creamy undertones.

• Use 1 tablespoon of dry mix or skip for a cleaner flavor profile.

Beef Broth

• Adds body and rounds out the soup.

• Use low-sodium for better control over seasoning.

• Substitute with vegetable broth for vegetarian versions.

Optional Additions

• Bell peppers, jalapeños, or chopped zucchini for extra vegetables.

• A splash of lime juice or a handful of fresh cilantro before serving.

Step-by-Step Instructions

This soup is as simple as it gets — the slow cooker does all the heavy lifting.

1. Brown the Beef (Optional but Recommended)

In a skillet over medium heat, brown the ground beef with diced onion and garlic. Season lightly with salt and pepper.

Tip: Drain excess grease before adding to the slow cooker.

This step enhances the flavor and texture, but if you’re short on time, you can add raw beef directly to the slow cooker — it will cook through during the long simmer.

2. Add Everything to the Slow Cooker

To the slow cooker, add:

• Cooked beef and onion mixture

• 1 can diced tomatoes

• 1 can Rotel (mild or spicy)

• 1 can black beans (drained and rinsed)

• 1 can pinto beans (drained and rinsed)

• 1½ cups corn (fresh, canned, or frozen)

• 2–3 cups beef broth (depending on how thick you like your soup)

• 1 packet taco seasoning

• 1 tablespoon dry ranch seasoning (optional)

Stir to combine.

3. Cook Low and Slow

• Low for 6–8 hours

• High for 3–4 hours

The longer it simmers, the deeper the flavor becomes.

4. Finish and Serve

Before serving, taste and adjust seasoning. Add a splash of lime juice or top with fresh cilantro for brightness.

Ladle into bowls and top with your favorite taco-style garnishes.

Tips, Variations & Substitutions

• Add heat: Use spicy Rotel, extra chili powder, or chopped jalapeños.

• Vegetarian: Skip the meat and double the beans or add lentils or veggie crumbles.

• Creamy version: Stir in a splash of heavy cream or a dollop of sour cream right before serving.

• Make it chunkier: Add chopped zucchini, carrots, or bell peppers in the last 2 hours.

• Low-carb: Omit corn and beans; substitute with riced cauliflower and extra ground meat or mushrooms.

Serving Ideas & Occasions

FAQs

Q1: Can I make this on the stovetop?

Yes. Brown the beef, add all ingredients to a large pot, and simmer uncovered for 30–40 minutes until flavors meld.

Q2: Can I freeze this soup?

Absolutely. Let it cool completely, portion into freezer-safe containers, and freeze for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove.

Q3: Do I have to use ranch seasoning?

Not at all. It’s a fun flavor twist, but you can skip it for a more traditional taste.

Q4: Can I use homemade taco seasoning?

Definitely. Use about 2–3 tablespoons of your homemade blend of chili powder, cumin, garlic powder, onion powder, paprika, oregano, and salt.

Q5: How can I thicken the soup?

Let it simmer uncovered for 30 minutes at the end, or mash some of the beans against the side of the slow cooker to naturally thicken it.

Q6: Is this soup spicy?

It’s mild by default, but the spice level can be adjusted based on the Rotel, seasoning, and added peppers.

Q7: Can I add rice or pasta?

Yes. Stir in cooked rice or small pasta (like elbow or ditalini) during the last 30 minutes of cooking. Add extra broth as needed.
