Why Day-Old Tortillas Work Best: Using day-old corn tortillas that have dried out slightly produces much crunchier chips that hold up better under warm red sauce. Fresh tortillas contain more moisture and take longer to crisp up.
Control the Crispy-to-Soggy Ratio: For chips with more crunch, toss only half the chips with the sauce and leave the other half on top, exposed to the air. For softer, saucier chilaquiles, coat all the chips thoroughly and let them sit for 2–3 minutes before serving.
Adjusting Heat Levels: Guajillo chiles are mild. For more heat, add 1–2 dried arbol chiles or a fresh serrano pepper to the sauce. For less heat, use only 2 guajillo chiles and increase the tomatoes slightly.
Make-Ahead Sauce: The red guajillo sauce can be made up to 5 days in advance and stored in an airtight container in the fridge. Reheat gently before tossing with the chips.
Frying Without a Thermometer: If you do not have a thermometer, test the oil by dropping in a small piece of tortilla. It should sizzle immediately and float to the surface. If it sinks and bubbles slowly, the oil is too cool.
Best Cheese Substitutes: If you cannot find Oaxaca cheese, whole-milk mozzarella or Monterey Jack are the best substitutes. Avoid using cheddar, which does not melt as smoothly and can taste too sharp.
Rotisserie Chicken Shortcut: One rotisserie chicken from the grocery store yields about 3–4 cups of shredded meat, which is perfect for this recipe. Remove the skin and shred the meat with two forks.
Egg Variations: For a richer dish, fry the eggs in the remaining chile-infused oil from the skillet. For a lighter version, poach the eggs and place them on top of the chilaquiles just before serving.
Serving Suggestions: Serve chilaquiles with refried beans on the side, a squeeze of fresh lime juice over the top, and extra hot sauce for those who want more heat. Sliced radishes add a fresh, crunchy contrast.
Why Chilaquiles Do Not Store Well: The chips absorb the sauce and lose all crispness within an hour of assembly. Always make chilaquiles fresh and eat them immediately for the best texture.
