Prep the oven and pan: Heat oven to 375°F (190°C).
Lightly oil a 9x13-inch baking dish. Spoon 1/2 cup salsa verde into the bottom and spread to coat.
Sauté aromatics: Warm olive oil in a skillet over medium heat. Add onion and a pinch of salt; cook 3–4 minutes until translucent.
Stir in garlic and jalapeño; cook 1 minute until fragrant. Remove from heat.
Make the filling: In a bowl, combine shredded chicken, sautéed aromatics, cumin, half the cilantro, 1/2 cup salsa verde, cream cheese or sour cream, and a squeeze of lime. Season with salt and pepper.
Mix until just combined.
Warm the tortillas: To prevent cracking, wrap tortillas in a damp towel and microwave 45–60 seconds, or lightly toast each side on a dry skillet for 10–15 seconds.
Assemble: Spread 2–3 tablespoons of filling down the center of each tortilla and sprinkle with a little cheese. Roll snugly and place seam-side down in the baking dish. Repeat until the dish is filled.
Sauce and cheese: Pour remaining salsa verde evenly over the enchiladas.
Top with the rest of the cheese.
Bake: Bake 15–20 minutes, until the cheese is melted and the sauce is bubbling around the edges.
Finish and garnish: Let rest 5 minutes. Add remaining cilantro, lime zest, and any optional toppings like avocado, radishes, or a drizzle of crema.
Serve: Scoop with a spatula and serve hot with extra lime wedges.
