Why This Soup Slaps (And Stays Low-Carb)

What makes it keto?

• We skip the beans and corn (sneaky carb bombs).
• We use low-carb aromatics like onions, garlic, and green chiles.
• We thicken with cream cheese and cheese—not flour.

The Ingredients You’ll Need

Save

Keep it simple, but don’t be shy with the seasoning. This soup thrives on bold flavors.

• 1 lb (450 g) ground beef (80/20 or 85/15)
• 2 tbsp olive oil or avocado oil
• 1 small onion, diced (about 1 cup)
• 3 cloves garlic, minced
• 1 red bell pepper, diced
• 1 4-oz can diced green chiles (mild or hot)
• 1 14.5-oz can diced tomatoes (no sugar added)
• 4 cups beef broth (low sodium)
• 3 oz cream cheese, softened
• 1 cup shredded cheddar or Mexican blend cheese
• 2 tsp chili powder
• 1 tsp ground cumin
• 1 tsp smoked paprika
• 1/2 tsp dried oregano
• 1/2 tsp salt (adjust to taste)
• 1/4 tsp black pepper
• Optional: 1/4 tsp chipotle powder or cayenne for heat

Toppings (you choose):

• Avocado slices or diced
• Sour cream
• Fresh cilantro
• Lime wedges
• Pickled jalapeños
• More shredded cheese (obviously)

How to Make It (Weeknight-Easy)

You’ll get dinner on the table in under 40 minutes. No slow cooker required—though you can use one if you want “set it and forget it” energy.

1. Heat oil in a large pot over medium-high. Add the ground beef. Break it up and cook until browned with crispy bits, about 6–8 minutes. Drain excess fat if needed (or don’t—flavor lives there, IMO).
2. Add onion and bell pepper. Sauté 4–5 minutes until softened. Stir in garlic for 30 seconds until fragrant.
3. Season like you mean it: chili powder, cumin, smoked paprika, oregano, salt, pepper, and optional chipotle/cayenne. Toast the spices for 30–60 seconds.
4. Add green chiles, diced tomatoes, and beef broth. Stir, bring to a simmer, and cook 10 minutes to let the flavors mingle.
5. Reduce heat to low. Stir in cream cheese until fully melted and smooth. Add shredded cheese and stir until silky. Taste and adjust salt.
6. Ladle into bowls and hit it with your favorite toppings. Squeeze of lime? Always.

Slow Cooker Option

Brown the beef with onion and pepper first. Transfer to slow cooker with everything except cheeses. Cook on Low 6–7 hours or High 3–4 hours. Stir in cream cheese and shredded cheese at the end until smooth.

Flavor Tweaks and Swaps

Save

Keep it fun. You can absolutely riff on this without breaking your macros.

• Meat swap: Use ground turkey or chicken if you prefer lighter. Add 1 tbsp butter for richness.
• Extra veg: Add zucchini or riced cauliflower for bulk with basically no carbs.
• Spice level: Double the green chiles or throw in jalapeño during the sauté if you like it spicy.
• Creaminess factor: More cream cheese = thicker, silkier soup. FYI, it also adds fat (keto win).
• No dairy? Use coconut cream instead of cream cheese/cheddar. Different vibe, still tasty.

What About Beans?

Classic taco soup usually leans hard on beans. Keto you says “nah.” If you absolutely need them, use a tiny amount of black soybeans (they’re lower net carb) and portion carefully. But honestly, you won’t miss them here.

Make-Ahead, Storage, and Reheating

This soup tastes even better the next day. It’s like the flavors did an overnight team-building retreat.

• Fridge: Store in airtight containers up to 4 days.
• Freezer: Freeze up to 2 months. Thaw overnight in the fridge.
• Reheat: Low and slow on the stove or microwave in short bursts. Add a splash of broth if it thickens too much.

Meal-Prep Tip

Keep the toppings separate. Fresh avocado waits until serving time. Lime wedges go on everything because you’re a person of taste.

Serving Ideas That Go Beyond the Bowl

Save

You can treat this soup like a sauce, IMO.

• Taco salad topper: Pour a ladle over shredded lettuce with avocado and salsa.
• Cauli-rice bowls: Spoon over garlicky cauliflower rice for extra volume.
• Cheesy bake: Transfer to a baking dish, blanket in cheese, and broil till bubbly. Serve with pork rinds for crunch.

FAQ

Can I make this dairy-free and still keep it keto?

Yes. Swap cream cheese for full-fat coconut cream and use a dairy-free shredded “cheese” or skip cheese entirely. The texture stays rich, and the carbs barely budge.

Will this soup kick me out of ketosis?

Unlikely if you stick to the portions. Each serving clocks in around 6g net carbs without toppings. Track your day, and you’re golden.

How do I make it thicker without flour or cornstarch?

Let it simmer uncovered to reduce, or add a bit more cream cheese and shredded cheese. You can also blend a small scoop of the soup (veggies + broth) and stir it back in. Works like a charm.

Can I use taco seasoning packets?

You can, but many packets include starch or sugar. Read labels carefully. Homemade seasoning tastes fresher and stays cleaner on carbs, IMO.

What’s the best ground beef for flavor?

85/15 hits the sweet spot. It browns nicely, keeps things juicy, and doesn’t make the soup greasy. If you use 90/10, add a splash more oil or butter for richness.

Is this kid-friendly?

Usually yes—just dial back the heat. Skip the cayenne/chipotle and offer toppings like cheese and sour cream. Kids love the taco vibes.

Conclusion

Keto Mexican Beef Taco Soup brings all the fun of taco night without all the carbs—and without a mountain of dishes. It’s bold, cozy, and endlessly customizable. Make it once, and it’ll slide into your weeknight rotation faster than you can say “pass the lime.” Now go ladle up a bowl and flex your low-carb magic.
