Heat olive oil in a large skillet over medium-high heat. Add chicken cubes, season with salt and pepper, and cook for 6–8 minutes until golden and cooked through. Remove chicken and set aside.
Reduce heat to medium and add butter to the same skillet. Once melted, add garlic and sauté for 1 minute.
Add paprika, smoked paprika, chili flakes, Dijon mustard, lemon juice, and honey. Stir for 30 seconds to combine.
Pour in chicken broth and let simmer for 2 minutes.
Return chicken to the skillet and coat well in the cowboy butter sauce.
Stir in parsley, chives, and cilantro. Simmer for an additional 3–4 minutes until sauce thickens slightly.
Serve warm with rice, pasta, potatoes, or bread.
