Cut 2 boneless, skinless chicken breasts evenly in half lengthwise. Place the chicken between two pieces of plastic wrap and use the flat side of a meat mallet to pound to an even ¼-inch thickness.
Season the flattened cutlets with 1 teaspoon salt, ½ teaspoon pepper, and 1 teaspoon garlic powder.
In 3 separate shallow dishes, place ½ cup flour, 2 eggs beaten with 1 teaspoon Dijon mustard, and 1 ¼ cups panko bread crumbs.
Dredge the cutlets in the flour, coating evenly. Next, coat them in the eggs, allowing any excess egg to drip back into the bowl from the cutlets. Lastly, coat them completely in the panko bread crumbs.
Heat ⅓ cup oil in a large skillet over medium-high heat. When the oil is hot, place 2 cutlets in the oil and fry for about 4-5 minutes on each side. The chicken should be golden brown and cooked through.
Remove the cooked chicken from the oil and place on a wire rack to allow any excess oil to drain off. Repeat this process with the remaining cutlets.
Sprinkle the hot schnitzel with coarse salt and serve with fresh lemon wedges if desired.
Notes
Make Ahead & Storage Instructions
In the Refrigerator: Store leftovers in an airtight container for up to 3 days.
To Reheat: I like to use an air fryer to reheat the schnitzel to keep it crispy. About 5 minutes at 375°F. Flip halfway so both sides get nice and toasty.
Freezer: Place in a freezer-safe airtight container and store in the freezer for up to 3 months. Thaw in the fridge overnight before reheating.
Make Ahead: Prep up to the frying step, and store the breaded chicken between parchment paper in the refrigerator for up to 24 hours or in the freezer for up to 3 months.
