Ingredients
Method
- Heat oil in a skillet over medium heat. Cook onion 4–5 minutes until soft, then add garlic and green chiles; cook 1 minute. Remove from heat.
- Spread ½ cup sauce in a 9x13-inch dish. Layer 6 tortillas, half the onion mixture, ½ cup sauce, and 1½ cups cheese. Repeat layers with remaining tortillas, onion mixture, 1 cup sauce, and 1½ cups cheese. Top with olives if using.
- Preheat oven to 375°F (190°C). Bake uncovered 20–22 minutes until cheese melts and sauce bubbles at the edges.
- Rest 5 minutes, then slice into squares. Garnish with cilantro and sour cream.
Notes
You can assemble the casserole up to a day ahead, cover it, and refrigerate. Add about 5 minutes to the bake time if cooking it straight from cold.
