In a 2 quart saucepan, melt the butter over medium heat. Stir in the flour, salt, and pepper. Cook while stirring for 1 minute.
Slowly pour in the milk and stir until smooth. Bring to a gentle simmer and cook, stirring frequently, for about 2 minutes until thickened.
Remove from heat and stir in the Monterey Jack cheese until melted.
Spoon 2 tablespoons of the sauce into a 5×7-inch baking dish and spread evenly over the bottom.
Prepare the Casserole
Cook the Vegetables: Melt butter in a 10 inch skillet over medium heat. Add the bell pepper, onion, and jalapeño. Cook, stirring occasionally, for 2 minutes.Stir in the garlic, salt, cumin, and chili powder. Cook for 1 minute.Stir the vegetables into the cheese sauce.
Soften the Tortillas: Heat 1 to 2 tablespoons of oil in the same skillet over medium high heat. Warm each tortilla for about 30 seconds per side until soft. Transfer to a paper towel lined plate.
Assemble the Casserole: Tear half of the tortillas into pieces and layer in the bottom of the dish.Add half of the chicken, half of the tomatoes, half of the sauce, and half of the cheddar cheese.Repeat the layers, ending with the remaining cheddar cheese on top. Place the baking dish on a rimmed baking sheet.
Bake: Bake uncovered for 25 to 30 minutes until bubbly and lightly golden on top. Let rest for 5 to 10 minutes before serving.
Notes
Do Not Rush the Sauce: Cook the roux for a full minute before adding the milk and stir constantly as it thickens. This ensures a smooth, creamy sauce without a floury taste.
Add the Cheese Off the Heat: Stir the Monterey Jack cheese into the sauce after removing it from the heat. This helps the cheese melt smoothly and prevents a grainy texture.
Layer Evenly: Spread the chicken, sauce, tortillas, and cheese evenly in each layer. This helps the casserole bake evenly and ensures every bite has good balance.
Let It Rest Before Serving: Allow the casserole to rest for 5 to 10 minutes after baking. This helps the layers set and makes it easier to serve.
If doubling the recipe, bake the casserole in an 8x8-inch baking dish.
