Why should I air fry frozen french fries?

When you buy a bag of frozen fries, you’ll see that they come with a variety of instructions on how to cook them in the oven, air fryer, pan or deep fryer.

When you cook them in the oven or air fryer, you don’t have to add extra oil, which makes that cooking process a healthier option.

The advantage of cooking them in an air fryer versus the oven is that they get extra crispy on the outside while still staying soft on the inside.


Garlic Parmesan Ranch Fries Ingredients: frozen fries, parmesan cheese, ranch seasoning, granulated garlic.
  • Frozen French Fries: Look for packages that say shoestring fries or fast food fries. These are the skinnier ones.
  • Parmesan Cheese: Use grated Parmesan instead of shredded or shaved. The grated Parmesan will stick to the fries better.
  • Ranch Seasoning: You can buy little packets that are used to make ranch dressing or buy the seasoning in a bottle. I use the bottled variety from Spiceology.
  • Granulated Garlic: I prefer granulated garlic to garlic powder, but either will work for this recipe.
  • Dipping Sauces: Ketchup, mayonnaise and ranch dressing are great options.
Substitutions: If you use thicker steak fries, follow the cooking instructions on the package. They will require a little more time in the air crisper.

How to make Parmesan ranch french fries

  1. STEP ONE: If your frozen fries have ice crystals on them, lay them on a paper towel-lined baking sheet for 5 minutes, so some of that ice melts. If they have too many crystals, the liquid will steam the fries instead of crisp them.

  1. STEP TWO: In a small bowl, combine the Parmesan cheese, ranch seasoning and granulated garlic.

  1. STEP THREE: Heat your Ninja Foodi or Woodfire Grill to Air Crisp, 400F degrees, 20 minutes. Place fries in a single layer, filling the air fryer basket and cook the fries for 5 minutes.
  1. STEP FOUR: Using a spatula, flip the fries, so they cook more evenly. You can also shake the basket, just be sure to grab it with a hot pad or towel. Cook for another 4-5 minutes.

NINJA PRO TIP: If you like extra crispy fries, cook them for 1-2 minutes longer.

  1. STEP FIVE: Once the fries are golden and crispy, transfer them to a large bowl.

You can also save the extra garlic parmesan ranch seasoning and use it on garlic bread, grilled chicken and grilled salmon.

There’s no great way to store leftover garlic parmesan french fries, because they start to lose their crispiness.

If you do have extra that you want to save, you can keep them in an airtight container in the refrigerator for 1-2 days. The best way to bring them back to life is to put them back in the Ninja Grill and Air Crisp them for a few minutes.

  1. My air fryer heats in a couple of minutes, do I really have to preheat it for 15-20 minutes?
