In a bowl, season the boneless chicken thighs with black pepper, paprika, and salt.
Toss until the chicken is evenly coated on all sides.
Pan-sear the chicken
Heat a drizzle of cooking oil in a pan over medium-low heat.
Add the chicken thighs and cook for 4 to 5 minutes per side, until nicely browned and cooked through.
Cooking time may vary depending on the thickness of your chicken.
Remove the chicken from the pan and set aside.
Sauté the aromatics
Using the same pan, add the diced onion and garlic. Cook for 1 to 2 minutes, stirring occasionally, until softened and fragrant.
Make the honey mustard sauce
Pour in the white wine to deglaze the pan. Use a spatula to scrape up the browned bits from the bottom, since that's where a lot of the flavor is.
Add the mustard and honey, then stir until everything is thoroughly combined. Pour in the heavy cream and mix until you have a smooth, creamy sauce.
Finish the sauce and serve
Add chopped parsley and season with salt to taste. Let the sauce simmer for about 30 seconds, then return the chicken to the pan and coat it in the sauce.
