Follow these simple steps to create your amazing Creamy Lemon & Dill Skillet Chicken:

1. Prep Chicken: Pat the chicken breasts dry with a paper towel. Season both sides with salt and pepper.
2. Heat Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Cook Chicken: Add the chicken breasts to the skillet. Cook for about 5-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
4. Sauté Garlic: In the same skillet, add the minced garlic and sauté for about 30 seconds until fragrant.
5. Add Broth and Cream: Pour in the chicken broth and heavy cream. Stir well to combine, scraping any brown bits from the bottom of the pan.
6. Incorporate Flavors: Add the lemon juice, lemon zest, chopped dill, and Dijon mustard to the skillet. Stir until everything is well combined.
7. Thicken Sauce: If you prefer a thicker sauce, mix the cornstarch with a tablespoon of cold water, then add it to the skillet. Let the sauce simmer for a few minutes until it thickens.
8. Return Chicken: Place the cooked chicken back into the skillet, allowing it to warm through and coat with the sauce for about 2-3 minutes.
9. Adjust Seasoning: Taste the sauce and adjust the seasoning with salt and pepper as needed.
10. Garnish: Remove from heat and garnish with lemon slices and additional dill for a pop of color and freshness.

By following these straightforward steps, you are bound to achieve an incredibly flavorful meal that will impress anyone at your dining table.
