How to Reheat Nachos to Crispy, Cheesy Perfection


Nachos are a crowd-pleasing appetizer or snack made of tortilla chips, cheese, and an array of tasty toppings. But leftover nachos often end up soggy and lacking their original crunch. Fortunately, with the right reheating method, you can revive yesterday’s nachos to their former glory. Here’s how to reheat nachos using the oven, microwave, or air fryer.

Reheating Nachos in the Oven

The oven allows you to reheat nachos gently and evenly for a crispy result.

What You Need

  • Leftover nachos
  • Oven-safe baking sheet or pan
  • Aluminum foil


  1. Preheat oven to 375°F.
  2. Place nachos in a single layer on a foil-lined baking sheet. Make sure chips don’t overlap.
  3. Cover pan with more foil, sealing the edges to keep in steam.
  4. Bake for 10-15 minutes until hot and crunchy.
  5. Remove foil and bake 2-3 more minutes to recrisp any soggy chips.

Pro Tip: For the best texture, avoid piling on heaps of toppings which can make nachos soggy and hard to reheat. Save extras like guacamole, salsa, and sour cream for serving.

Common Questions

How long should you reheat nachos in the oven? Depending on amount, nachos take 10-15 minutes covered in foil plus 2-3 minutes uncovered. Watch carefully near the end to avoid burning.

Can you reheat nachos with toppings in the oven? Yes, but go light on wet ingredients like salsa, cheese, beans or it may create sogginess. Save excess toppings to add after reheating.

Reheating Nachos in the Microwave

The microwave provides a fast, convenient way to reheat nachos when you’re short on time.

What You Need

  • Leftover nachos
  • Microwave-safe plate or bowl


  1. Place nachos on a microwave-safe plate in a single layer.
  2. Microwave on high in 30 second intervals until heated through, about 1-3 minutes total.
  3. Allow to sit 1 minute before serving.

Pro Tip: Microwaves can create hot and cold spots. Rotate the plate every 30 seconds for even reheating. Add a glass of water along with the nachos to create steam.

Common Questions

How long should you microwave nachos? Cook times vary based on amount and power level. Nachos take 1-3 minutes on high in a typical microwave. Heat in 30 second bursts then check to avoid overcooking.

How can you make nachos crispy again in the microwave? The key is to go low and slow. Cook at 50% power for a longer time to gently crisp without scorching. Let sit 1 minute before eating so chips fully recrunch.

Reheating Nachos in the Air Fryer

The hot air circulating technology of an air fryer makes it ideal for crisping up leftover nachos.

What You Need

  • Leftover nachos
  • Air fryer


  1. Place a single layer of nachos in the air fryer basket.
  2. Air fry at 375°F for 3-5 minutes, shaking the basket halfway through.
  3. Check frequently and cook until heated through and crispy.

Pro Tip: Like the oven, limit cheese and wet toppings when air frying or they’ll make nachos soggy. Brush both sides of chips with oil before air frying for extra crunch.

Common Questions

How long do you air fry nachos? Cook time can vary based on amount and air fryer. Most take 3-5 minutes at 375°F to reheat nachos evenly. Shake or flip chips halfway for optimum crispness.

What’s the best way to crisp up nachos in an air fryer? Brush both sides of chips lightly with oil before air frying. Cook in a single layer, shaking the basket occasionally for even crisping.
