Pat the chicken pieces dry with paper towels and season with paprika, Italian seasoning, salt, and black pepper.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken in a single layer and cook for 4 to 5 minutes without moving it too much until golden brown.
Flip the chicken pieces and cook for another 3 to 4 minutes until fully cooked.
Reduce the heat to medium and add the butter to the skillet.
Stir in the minced garlic and cook for about 30 seconds until fragrant.
Add the lemon juice and toss the chicken until every piece is coated in the garlic butter sauce.
Sprinkle with chopped fresh parsley and optional red pepper flakes.
Serve immediately with rice, mashed potatoes, pasta, roasted vegetables, or a fresh salad.
