4 teaspoons sweet paprika
4 teaspoons dried thyme
2 teaspoons onion powder
2 teaspoons garlic powder
1 teaspoon fine salt
3/4 teaspoon cayenne pepper
3/4 teaspoon ground black pepper
4 (8-ounce) boneless skinless chicken breasts
2 to 3 tablespoons canola oil, divided
Lemon wedges, for serving
Whisk together 4 teaspoons sweet paprika, 4 teaspoons dried thyme, 2 teaspoons onion powder, 2 teaspoons garlic powder, 1 teaspoon fine salt, 3/4 teaspoon cayenne pepper, and 3/4 teaspoon ground black pepper in a small bowl until evenly combined.
Slice each of 4 (8-ounce) boneless skinless chicken breasts horizontally through the center to create 2 thinner breasts (8 total). Working with half of a breast at a time, cover in a layer of plastic wrap and pound each to about 1/2-inch thick. Repeat with remaining breasts.
Pat chicken breasts dry, and evenly coat in the prepared seasoning.
Heat 1 tablespoon of the canola oil in a large nonstick skillet over medium-high until the oil shimmers. Working in batches, cook the chicken, flipping once, until cooked through and a thermometer inserted in the thickest part registers at least 155 F, about 3 minutes per side.
