Crunchy French Fries

Pro tips

• Spread fries in a single layer on a microwave-safe plate and cover loosely to allow steam to escape—this prevents them from becoming soggy.
• Pat fries lightly with a paper towel after microwaving to remove any remaining surface moisture before adding beef fat.
• Toss fries with melted beef fat just before air frying to ensure even coating and maximize crispness.
• Shake the air fryer basket halfway through cooking to promote uniform browning on all sides.

Substitutions

• Frozen steak fries → frozen shoestring or crinkle-cut fries (adjust cooking time by 1–2 minutes)
• Beef fat → duck fat, avocado oil, or vegetable oil (note: beef fat provides the richest flavor)
• Salt → garlic salt, seasoned salt, or cajun seasoning (for added flavor depth)

Storage & make-ahead

Store cooled leftover fries in an airtight container at room temperature for up to 2 days; reheat in the air fryer at 350°F for 3–4 minutes to restore crispness.

Equipment

Microwave · Air fryer

Why microwave the fries before air frying?

Microwaving removes surface moisture, which prevents steaming in the air fryer and allows them to crisp more effectively.

Can I use oil instead of beef fat?

Yes, though beef fat adds a richer flavor. Vegetable oil or avocado oil work as substitutes for a neutral taste.

How do I know when the fries are done?

They should be golden brown and crispy throughout. Check at the halfway mark and shake the basket to ensure even cooking.

Can I make these ahead of time?

Best served immediately, but leftovers can be stored in an airtight container for 1–2 days and reheated in the air fryer at 350°F for 3–4 minutes.

What size bag of frozen fries works best?

A 28 oz bag is standard and fits most air fryer baskets; larger bags may need to be cooked in batches.
