Heat olive oil in a large skillet over medium-high heat. Season the chicken breasts with salt, pepper, and smoked paprika. Sear for about 5 minutes per side until golden brown. Remove from the skillet and set aside.
Make the Sauce
In the same pan, melt the butter and sauté the minced garlic until fragrant, about 1 minute. Pour in the chicken broth and let it simmer for 2 minutes, scraping up any browned bits from the pan.
Add the Creamy Elements
Lower the heat to medium and whisk in the heavy cream, Dijon mustard, whole grain mustard, and honey. Stir until the DIY honey mustard sauce becomes smooth and well combined.
Thicken (If Needed)
If you prefer a thicker sauce, mix 1 teaspoon of cornstarch with 1 tablespoon of water and whisk it into the sauce.
Simmer and Cook the Chicken
Return the seared chicken to the skillet, spooning the sauce over it. Cover and let it simmer for 8-10 minutes or until the chicken is fully cooked (internal temperature reaches 165°F).
Garnish and Serve
Sprinkle fresh thyme and parsley over the dish. Serve hot with rice, mashed potatoes, or roasted vegetables.
