What You’ll Need

• 1 pound ground beef (85–90% lean), or ground turkey
• 1 tablespoon avocado oil or olive oil
• 1 small yellow onion, diced
• 1 bell pepper (any color), diced
• 2 cloves garlic, minced
• 1 medium zucchini, diced (optional for extra veg)
• 1 (10-ounce) can diced tomatoes with green chiles, drained
• 2 tablespoons tomato paste
• 1/2 cup beef broth (low-sodium)
• 1 1/2 tablespoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon dried oregano
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4–1/2 teaspoon cayenne (optional, to taste)
• Salt and black pepper, to taste
• 1 1/2 cups shredded cheese (cheddar, Monterey Jack, or a blend)
• 2 tablespoons fresh cilantro, chopped
• Juice of 1/2 lime
• Toppings: avocado or guacamole, sour cream, sliced jalapeños, sliced green onions, shredded lettuce

How to Make It

1. Warm the pan. Set a large skillet over medium-high heat. Add the oil and let it heat until it shimmers.
2. Brown the meat. Add the ground beef and break it up with a spatula. Cook until no longer pink and starting to brown, about 5–6 minutes.

   Season lightly with salt and pepper.

3. Sauté the veggies. Push the meat to one side. Add onion and bell pepper to the open space. Cook 3–4 minutes until softened.

   Stir in the garlic and zucchini (if using) and cook 1 more minute.

4. Add seasonings. Sprinkle in chili powder, cumin, smoked paprika, oregano, garlic powder, onion powder, and cayenne. Stir well so the spices coat the meat and vegetables.
5. Build the sauce. Add the tomato paste and cook for 30 seconds to bloom it. Pour in the beef broth and the drained tomatoes with green chiles.

   Stir until everything is combined and saucy.

6. Simmer and reduce. Lower the heat to medium and simmer for 4–6 minutes, stirring occasionally, until the mixture thickens and most of the liquid reduces. Taste and adjust salt, pepper, or heat.
7. Add lime and cilantro. Turn off the heat. Stir in lime juice and half the cilantro for brightness.
8. Melt the cheese. Sprinkle the shredded cheese over the skillet.

   Cover for 1–2 minutes, or slide the skillet under the broiler for 1–3 minutes, until the cheese is melted and bubbly.

9. Finish and serve. Garnish with the remaining cilantro. Add toppings like avocado, sour cream, jalapeños, or green onions. Serve as is, over shredded lettuce, or with cauliflower rice.

Keeping It Fresh

Store leftovers in an airtight container in the fridge for up to 4 days.

The flavors often get even better after a night’s rest. Reheat in a skillet over medium heat with a splash of broth to keep it juicy, or microwave in 30-second bursts.

For freezing, skip the fresh toppings and cheese. Cool the cooked meat mixture, then freeze up to 3 months.

Thaw overnight in the fridge, reheat on the stove, and add cheese and toppings just before serving.

Why This is Good for You

• Low in carbs, high in satisfaction: You get classic taco flavor and texture without the tortilla load, helping you stay on track with keto or low-carb goals.
• Protein-forward: Ground beef or turkey supports satiety and muscle maintenance.
• Healthy fats: Avocado, cheese, and sour cream add fats that help keep you full and support ketosis.
• Veggie boost: Bell pepper, onion, and zucchini bring fiber, micronutrients, and a little crunch.
• Customizable sodium and spice: You control the seasonings, which is great if you’re watching salt or heat.

Common Mistakes to Avoid

• Skipping the drain step: If your meat releases a lot of fat, drain excess grease before adding the spices and liquids. Too much grease can dull the flavor and make it heavy.
• Not blooming the tomato paste: Cooking the paste briefly deepens flavor. Adding it cold can make the sauce taste flat.
• Overcooking the veggies: You want them tender with a little bite.

  Mushy peppers and zucchini can make the skillet feel soggy.

• Adding toppings too early: Avocado and sour cream should go on right before serving so they stay fresh and vibrant.
• Going overboard on broth: Start with the listed amount and let it reduce. Too much liquid will dilute the taco flavor.

Alternatives

• Different proteins: Use ground turkey, chicken, bison, or a mix of beef and chorizo. For a vegetarian option, try crumbled tofu or a low-carb meat alternative and boost the spices.
• Cheese swaps: Pepper Jack for heat, Colby Jack for mild melt, or a Mexican blend for convenience.

  For dairy-free, use a good melting vegan cheese or skip and top with guacamole.

• Veggie variations: Swap zucchini for riced cauliflower, add mushrooms for umami, or toss in spinach at the end to wilt.
• Spice tweaks: Add chipotle powder for smoky heat, or use a premade sugar-free taco seasoning if you’re in a rush.
• Serving ideas: Spoon over cauliflower rice, stuffed into lettuce wraps, or over a bed of shredded romaine for a taco bowl.

FAQ

Is this truly keto-friendly?

Yes. Without tortillas or beans, carbs stay low. The main carbs come from veggies and tomatoes.

Portion size and toppings matter, but this fits comfortably in a keto or low-carb plan.

Can I make it less spicy?

Absolutely. Skip the cayenne and choose mild diced tomatoes. Use Monterey Jack or mild cheddar, and avoid jalapeño toppings.

You’ll still get great flavor from the cumin, paprika, and oregano.

How can I make it spicier?

Add more cayenne, throw in chopped fresh jalapeños with the onions, or finish with hot sauce. A touch of chipotle in adobo brings smoky heat and depth.

What if I don’t have tomato paste?

Use a couple tablespoons of sugar-free salsa or a splash of low-sugar ketchup and simmer longer to reduce. The flavor won’t be identical, but it will still be tasty and cohesive.

Can I meal prep this?

Yes.

Cook the base through step 7, cool, and store in portions. Reheat and add cheese and toppings just before eating. It holds up well for several days.

What cheese melts best?

Freshly shredded cheddar or Monterey Jack melts smoothly and avoids additives.

Pre-shredded works in a pinch, but it may not melt as creamy.

How do I keep it from getting watery?

Drain excess fat after browning, drain the canned tomatoes well, and simmer until the sauce thickens. If needed, cook uncovered for a few extra minutes to reduce.

Can I add beans or corn?

If you’re not strict keto, you can add a small amount of black beans or corn. For strict keto, skip them and stick with low-carb veggies like zucchini or mushrooms.

What pan should I use?

A large cast-iron or stainless-steel skillet works best for good browning and even heat.

Nonstick is fine, but you may not get the same sear on the meat.

How many servings does this make?

It makes about 4 servings as a main. If you add cauliflower rice or a big salad, you can stretch it to 5.
