Ingredients Breakdown

• 1 lb (450 g) ground beef (80/20 for best flavor and fat content)
• 1 tbsp avocado oil or olive oil (if your beef is very lean)
• 1 small onion, diced (about 1/2 cup; optional if you’re ultra-low carb)
• 2 cloves garlic, minced
• 1 bell pepper, diced (green or red; adds crunch without many carbs)
• 1 small jalapeño, minced (optional for heat)
• 2 tbsp tomato paste
• 1/2 cup canned diced tomatoes (drained well) or 1/3 cup sugar-free salsa
• 1/4 cup beef broth (or water)
• 2 tsp chili powder
• 1 tsp ground cumin
• 1/2 tsp smoked paprika
• 1/2 tsp dried oregano
• 1/2 tsp sea salt (plus more to taste)
• 1/4 tsp black pepper
• 1/4 tsp crushed red pepper flakes (optional)
• 1 1/2 cups shredded cheese (cheddar, Monterey Jack, or a Mexican blend)
• 1/4 cup full-fat sour cream (for serving)
• 1 avocado, diced or sliced
• Fresh cilantro, chopped
• Lime wedges (game-changer for brightness)
• Optional add-ins: 1 cup riced cauliflower for extra bulk, sliced black olives, pickled jalapeños

How to Make It – Instructions

1. Heat the skillet: Place a large skillet over medium-high heat.

   Add oil if your beef is lean.

2. Brown the beef: Add ground beef and break it up with a spatula. Cook until no longer pink and browned in spots, 5–7 minutes. Drain excess fat if needed (leave 1–2 tsp for flavor).
3. Sauté aromatics: Add onion, bell pepper, and jalapeño.

   Cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.

4. Spice it right: Sprinkle in chili powder, cumin, smoked paprika, oregano, salt, black pepper, and red pepper flakes. Toss to coat the beef and veggies.
5. Tomato boost: Stir in tomato paste; cook 1 minute to caramelize.

   Add diced tomatoes (or salsa) and beef broth. Mix and bring to a simmer.

6. Optional cauliflower rice: If using, stir in now. Cook 2–3 minutes until tender and most liquid is absorbed.
7. Cheese time: Reduce heat to low.

   Sprinkle cheese evenly over the skillet. Cover and let it melt, 1–2 minutes, until bubbly and irresistible.

8. Top and serve: Remove from heat. Finish with sour cream, avocado, cilantro, and a squeeze of lime.

   Serve straight from the pan like a boss.

Storage Instructions

• Fridge: Cool completely, then store in an airtight container for 3–4 days.
• Freezer: Freeze the beef mixture without fresh toppings for up to 2 months. Thaw overnight in the fridge, reheat, then add cheese and toppings.
• Reheat: Skillet over medium heat with a splash of broth or water until hot. Or microwave in 45–60 second bursts, stirring between.

Nutritional Perks

• Keto-aligned macros: High fat from beef, cheese, and avocado keeps you satisfied and supports ketosis.
• Protein power: Ground beef delivers essential amino acids for muscle maintenance.
• Micronutrient boost: Bell peppers and tomatoes add vitamin C and antioxidants; cilantro and lime add brightness without carbs.
• Low-carb friendly: Skip the tortillas and you’re keeping net carbs in check.

  FYI, onions and tomatoes add small amounts, so portion accordingly if you’re strict.

Common Mistakes to Avoid

• Skipping the drain: If your beef renders a lot of fat, drain some before adding spices. Too greasy = muted flavors.
• Watery skillet: Don’t dump in liquid like it’s soup. Simmer until thick and saucy before adding cheese.
• Cheese overload (yes, it’s possible): More isn’t always better.

  Too much can turn the skillet greasy instead of gooey.

• Overcooking veggies: Mushy bell peppers aren’t the vibe. Keep them slightly crisp for texture.
• Under-seasoning: Salt wakes everything up. Taste and adjust before topping with cheese.

Mix It Up

• Protein swap: Use ground turkey, chicken, or chorizo.

  If using lean meat, add 1–2 tbsp oil for richness.

• Fajita remix: Add sliced mushrooms and extra peppers. Finish with pepper jack for heat.
• Burrito bowl (keto edition): Serve over shredded lettuce or cabbage with extra avocado and salsa.
• Eggs on top: Crack 2–3 eggs into little wells, cover, and steam 3–4 minutes for a brunchy twist.
• Chipotle-lime kick: Add 1 tsp chipotle in adobo to the tomato paste for smoky heat and a squeeze of extra lime.

FAQ

Can I make this dairy-free?

Yes. Skip the cheese and use a dairy-free shredded cheese alternative or melt in a dollop of coconut cream for richness.

Top with avocado and a dairy-free sour cream substitute.

Is this spicy?

Mild by default. For heat, keep the jalapeño seeds, add red pepper flakes, or use pepper jack. For no heat, skip jalapeño and flakes entirely.

What can I use instead of tomato paste?

Use an extra 2–3 tablespoons of sugar-free salsa or 1/4 cup crushed tomatoes, then simmer longer to reduce.

Tomato paste just speeds up the flavor payoff.

How do I keep it strictly keto?

Reduce onion to 2 tablespoons or omit; use drained tomatoes sparingly or choose a low-carb salsa. Don’t add corn or beans (save those for non-keto guests).

Can I make it ahead?

Absolutely. Cook the beef mixture, cool, and store.

Reheat, add cheese to melt, then finish with fresh toppings right before serving for best texture.

What if I don’t have chili powder?

Mix 1 tsp paprika, 1/2 tsp cumin, 1/4 tsp garlic powder, 1/4 tsp onion powder, and a pinch of cayenne. Boom—instant DIY blend.

How can I thicken a watery skillet fast?

Simmer uncovered on medium-high for 2–3 minutes, or stir in 1–2 tablespoons of cream cheese for a thicker, creamier finish. Works like a charm.
