Ingredients
For the Chicken:

  • 4 boneless, skinless chicken thighs (or breasts)
  • 1 tbsp olive oil
  • 1 tsp smoked paprika
  • 1 tsp garlic powder
  • 1 tsp dried thyme
  • ½ tsp onion powder
  • 1 tsp kosher salt
  • ½ tsp black pepper

For the Creamy Garlic Herb Sauce:

  • 2 tbsp unsalted butter
  • 1 small yellow onion, finely diced
  • 3 garlic cloves, minced
  • 8 oz cremini mushrooms, sliced
  • 1 lb baby potatoes, halved and parboiled (5 minutes in salted water)
  • ½ cup dry white wine (optional, substitute with broth)
  • 1 cup low-sodium chicken broth
  • ½ cup heavy cream
  • 1 tbsp Dijon mustard
  • 1 tsp fresh thyme leaves (or ½ tsp dried)
  • 2 cups fresh baby spinach
  • 1 tbsp all-purpose flour (for thickening)
  • Salt and pepper to taste
  • Fresh parsley, chopped (for garnish)

Step-by-Step Instructions

  1. Prep the Chicken:
    • Pat chicken dry and season evenly with paprika, garlic powder, thyme, onion powder, salt, and pepper.
  2. Sear the Chicken:
    • Heat olive oil in a large skillet over medium-high heat. Sear chicken for 5-6 minutes per side until golden brown. Transfer to a plate.
  3. Build the Sauce Base:
    • Reduce heat to medium. Melt butter in the skillet. Add onions and sauté for 2 minutes. Stir in garlic and mushrooms, cooking 4-5 minutes until mushrooms caramelize.
  4. Deglaze & Thicken:
    • Pour in white wine (or broth) to deglaze the pan, scraping up browned bits. Sprinkle flour over the mixture and stir for 1 minute. Gradually whisk in chicken broth, cream, and Dijon mustard. Add thyme and parboiled potatoes.
  5. Simmer & Combine:
    • Return chicken to the skillet, nestling it into the sauce. Reduce heat to low, cover, and simmer for 12-15 minutes until chicken reaches 165°F internally.
  6. Finish with Spinach:
    • Stir in spinach until wilted (1-2 minutes). Adjust seasoning with salt and pepper.
  7. Serve:
    • Garnish with parsley. Pair with crusty bread or a simple salad.

Pro Tips for Success

  • Crispy Potatoes: For extra texture, pan-fry parboiled potatoes in the skillet for 2-3 minutes before adding the sauce.
  • Chicken Breasts Option: Reduce cooking time to 8-10 minutes to avoid drying out.
  • Dairy-Free Twist: Substitute heavy cream with coconut cream and butter with olive oil.
