📖 Instructions

1. Prep Your Ingredients: Start by getting everything ready. Preheat your oven to a cozy 375°F (190°C) and grab your favorite 9x13 inch baking dish; give it a light spray with cooking spray. If your chicken isn't already shredded, now's the time! I usually boil a couple of chicken breasts and then use two forks to pull them apart, but a rotisserie chicken works wonders for saving time, too. Have your shredded Monterey Jack cheese divided and ready, along with those green chiles.
2. Make the Roux (Sauce Base): In a large, sturdy skillet or pot, melt the butter over medium heat. Once it’s fully melted and looking nice and golden, sprinkle in the all-purpose flour. Whisk, whisk, whisk! Keep whisking continuously for about 1-2 minutes until you’ve got a smooth, pale paste, often called a roux. This step is super important for avoiding a lumpy sauce later on, so don’t rush it. It should smell a little nutty, a good sign!
3. Build the Creamy Sauce: Slowly, and I mean slowly, pour in the warm milk while you continue to whisk like your life depends on it. Adding it gradually prevents lumps and helps the sauce thicken evenly. After the milk is incorporated, pour in the chicken broth and continue whisking until the sauce starts to thicken and bubble gently. This should take about 5-7 minutes. It'll go from watery to a beautiful, velvety consistency.
4. Flavor the Sauce: Once the sauce is thick and smooth, stir in the undrained diced green chiles, cumin, and garlic powder. Give it a good taste test now and add salt and black pepper as needed. Remember, you can always add more, but you can’t take it out! I usually start with a generous pinch of each and adjust. This is where the magic happens and the flavors really start to sing.
5. Add Cheese to Sauce: Reduce the heat to low and stir in 1 cup of the shredded Monterey Jack cheese. Continue stirring until the cheese is completely melted and the sauce is wonderfully smooth and cheesy. Set this luscious sauce aside for a moment. Don’t let it boil too vigorously once the cheese is in, as it can separate.
6. Assemble the Enchiladas: Now for the fun part! Take one of your flour tortillas. Spoon about 2-3 tablespoons of the shredded chicken down the center. Then, sprinkle a small amount of the remaining shredded cheese over the chicken. Roll the tortilla up tightly and place it seam-side down in your prepared baking dish. Repeat this with all the remaining tortillas, chicken, and cheese, arranging them snugly in the dish. Don't worry if they're a little cozy in there.
7. Smother with Sauce and Bake: Once all your enchiladas are rolled and nestled in the dish, generously pour the remaining creamy white sauce evenly over the top, making sure every tortilla is nicely coated. Nobody wants a dry enchilada! Sprinkle the remaining 1 cup of shredded Monterey Jack cheese over the sauce.
8. Bake to Golden Perfection: Pop the baking dish into your preheated oven. Bake for 25-30 minutes, or until the enchiladas are bubbly around the edges and the cheese on top is melted, golden, and just a little bit browned in spots. That golden crust is the sign of true comfort!
9. Rest, Garnish, and Serve: Once out of the oven, resist the urge to dive in immediately! Let the enchiladas rest for about 5-10 minutes. This helps the sauce set a bit and prevents everything from falling apart when you serve it. Garnish with fresh chopped cilantro and a dollop of sour cream if you like (I always do!). Serve warm and watch them disappear!
