Prep your toppings and shells: Rinse and pat dry lettuce leaves or warm low-carb tortillas. Set out cheese, avocado, salsa, and sour cream so assembly is easy.
Sauté aromatics: Heat oil in a large skillet over medium heat.
Add onion and cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds, just until fragrant.
Brown the turkey: Add the ground turkey to the skillet. Break it up with a spatula and cook 5–7 minutes until no longer pink.
Don’t overcook—keep it juicy.
Season it right: Sprinkle in chili powder, cumin, smoked paprika, oregano, salt, pepper, and cayenne if using. Stir to coat the meat evenly.
Add tomato paste and liquid: Mix in tomato paste, then pour in broth or water. Simmer 3–5 minutes until the sauce thickens and clings to the turkey.
Finish with lime: Turn off the heat and stir in lime juice.
Taste and adjust salt or spice as needed. Add chopped cilantro if you like.
Assemble tacos: Spoon the turkey into lettuce cups or tortillas. Top with cheese, avocado, salsa, sour cream, and a squeeze of lime.
Serve immediately.
