Prep the chicken: Pat the chicken dry and season both sides with salt, pepper, cumin, chili powder, and smoked paprika. This helps the spices stick and keeps the flavor consistent throughout.
Sauté aromatics: In a large skillet or Dutch oven, heat olive oil over medium heat.
Add the onions and cook 3–4 minutes until softened. Stir in the garlic for 30 seconds until fragrant.
Add salsa verde: Pour in the salsa verde and bring to a gentle simmer. If your salsa is very thick, add a splash of chicken broth to loosen it slightly.
Cook the chicken: Stovetop: Nestle the chicken into the sauce.
Cover and simmer on low for 15–20 minutes, flipping once, until the internal temperature reaches 165°F (74°C).
Oven: Transfer everything to a baking dish. Cover with foil and bake at 375°F (190°C) for 25–30 minutes, or until cooked through.
Slow cooker: Add onions, garlic, chicken, and salsa to the slow cooker. Cook on Low for 4–5 hours or High for 2–3 hours.
Shred and finish: Remove the chicken to a plate and shred with two forks.
Return it to the sauce, stir in lime juice, and simmer 2–3 minutes so it soaks up the flavors. Taste and adjust salt or acidity as needed.
Garnish and serve: Top with chopped cilantro and, if you like, sliced jalapeño. Serve in bowls, tacos, burritos, or over rice, quinoa, or cauliflower rice.
