Step 1

Season chicken with 1 teaspoon salt and 1/2 teaspoon pepper. Dredge chicken in 4 tablespoons flour until evenly coated.

Step 2

Heat canola oil and butter in a large cast iron skillet over medium heat.

Step 3

Working in batches, add chicken to the skillet in a single layer and cook until golden brown and cooked through, reaching an internal temperature of 165 degrees F, about 4-5 minutes per side; set aside. Reduce heat to medium low.

Step 4

Whisk in remaining 1 1/2 tablespoons flour until lightly browned, about 1 minute.

Step 5

Gradually whisk in chicken stock and lemon juice. Bring to a boil; reduce heat and simmer, stirring occasionally, until reduced and slightly thickened, about 3 minutes. Stir in dill; season with salt and pepper, to taste. Return chicken to the skillet.

Step 6

Serve immediately.
