1poundbonelessskinless chicken breasts, thinly sliced into bite-sized strips
½teaspoonfine sea saltplus more to taste
½teaspoonfreshly ground black pepperplus more to taste
1tablespoonall-purpose flour
4tablespoonsunsalted butterdivided
1poundasparagustrimmed and cut diagonally into ¾-inch pieces
3large garlic clovesminced or pressed
⅓cupchicken stockor broth
1medium lemonzested and juiced (about 2 tablespoons juice)
2tablespoonsfresh dill or basilchopped (optional for garnish)
Instructions
Season and Coat the Chicken: Place the sliced chicken pieces into a medium-sized mixing bowl. Generously season with fine sea salt and freshly ground black pepper, making sure each piece is well-flavored before cooking. Sprinkle the all-purpose flour over the chicken, then use a spoon or clean hands to gently toss and coat every piece evenly. The flour gives the chicken a light crust when cooked and helps thicken the sauce later. Once coated, set the bowl aside while you prepare the vegetables.
Sauté the Asparagus to Perfection: In a large sauté pan or nonstick skillet, melt 2 tablespoons of butter over medium-high heat. When the butter starts to foam, add the asparagus pieces in an even layer. Lightly season with a pinch of salt and pepper. Sauté for about 2 minutes, stirring occasionally, until the asparagus turns bright green and begins to soften but still has a slight crunch. Add the minced garlic to the pan and cook for 1 additional minute, stirring constantly to prevent burning. The garlic should become fragrant and golden without turning bitter. Transfer the asparagus and garlic mixture to a clean plate and set aside.
Brown the Chicken Evenly: Return the pan to the heat and add the remaining 2 tablespoons of butter, swirling to coat the bottom of the skillet. Once the butter is melted and hot, carefully add the floured chicken pieces in a single layer. Let them cook undisturbed for 2 to 3 minutes so the bottoms develop a golden-brown crust. After the first side is seared, toss or stir the chicken and continue cooking for another 3 to 5 minutes, until the pieces are cooked through and lightly browned on all sides. The chicken should no longer be pink in the center.
Deglaze and Build the Sauce: Pour the chicken stock into the pan with the cooked chicken. Use a wooden spoon to gently scrape the bottom of the pan, lifting up any browned bits that have stuck. These caramelized bits add incredible flavor to the sauce. Stir in the freshly grated lemon zest and lemon juice, then add a few extra twists of black pepper to bring out the bright, peppery flavor.
Combine and Finish the Dish: Return the cooked asparagus and garlic mixture to the pan. Toss everything together gently, making sure the chicken and vegetables are evenly coated with the lemon-butter sauce. Allow the mixture to simmer for about 1 minute, just until the sauce slightly thickens and clings to the chicken and asparagus. Taste and adjust seasoning with extra salt, pepper, or lemon juice as desired.
Garnish and Serve Warm: Transfer the lemon pepper chicken and asparagus to a serving platter or individual plates. For a fresh finishing touch, sprinkle generously with chopped dill or basil if using. Serve immediately while warm, and enjoy this flavorful, protein-rich, and veggie-packed dish with your favorite sides or on its own for a lighter meal.
Notes
Use fresh, high-quality chicken breasts for the best flavor and texture.
Slice chicken evenly to ensure consistent cooking.
Trim woody ends off asparagus to keep it tender and pleasant to eat.
Fresh lemon juice and zest create a brighter, fresher flavor compared to bottled lemon juice.
Use unsalted butter to control seasoning and enhance the sauce’s flavor.
Don’t overcrowd the pan when cooking chicken to allow proper searing instead of steaming.
Lightly dusting chicken with flour improves browning and helps thicken the sauce.
Serve immediately for the best taste and texture, as asparagus loses crunch when reheated.
