One-Pan Keto Lemon Herb Chicken

This one-pan keto lemon herb chicken features boneless, skinless chicken thighs seared in olive oil until golden, then simmered with bright lemon zest and juice, garlic, and a blend of parsley, thyme, and rosemary. The chicken stays tender and juicy with a lightly crisp exterior, delivering a bold, fresh flavor profile and a satisfying balance of protein and healthy fats. It is ideal for busy weeknights, make-ahead meal prep, or entertaining, and pairs perfectly with keto-friendly sides like roasted broccoli, sautéed green beans, cauliflower mash, or a crisp arugula salad with cucumber and feta.

Ingredients

For the lemon herb chicken

2 pounds boneless skinless chicken thighs patted dry
1 1/2 teaspoons fine sea salt
1/2 teaspoon freshly ground black pepper
1 teaspoon garlic powder
1/2 teaspoon smoked paprika or regular paprika
3 tablespoons extra-virgin olive oil divided
3 tablespoons unsalted butter
4 cloves garlic minced
1 medium lemon zested and juiced separately
1/3 cup chicken broth low-sodium, no sugar added
1 tablespoon fresh parsley finely chopped, plus more for garnish
1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
1 teaspoon fresh rosemary finely chopped, or 1/2 teaspoon dried rosemary
1/4 teaspoon red pepper flakes optional, for gentle heat
1 tablespoon extra-virgin olive oil for finishing, optional

Instructions

Place the chicken thighs on a cutting board and pat them very dry with paper towels so they sear well in the pan.
In a small bowl combine the sea salt, black pepper, garlic powder, and smoked paprika, then sprinkle the mixture evenly over both sides of the chicken and gently rub to coat.
Zest the lemon into a separate small bowl, then cut the lemon in half and squeeze the juice into another bowl, discarding any seeds and keeping the zest and juice separate.
If time allows, cover the seasoned chicken and refrigerate for at least 30 minutes and up to 8 hours to let the flavors penetrate, then bring to room temperature for about 15 minutes before cooking.
Heat 2 tablespoons of the olive oil in a large skillet over medium-high heat until the oil is shimmering but not smoking.
Add the chicken thighs to the hot skillet in a single layer without crowding and cook undisturbed until the bottoms are deep golden brown and crisp around the edges, about 5 to 7 minutes.
Flip the chicken thighs with tongs and cook until the second side is browned and the chicken is nearly cooked through, about 4 to 5 minutes more, then transfer the chicken to a plate and tent loosely with foil.
Reduce the heat to medium and add the butter and remaining 1 tablespoon olive oil to the same skillet, scraping up any browned bits from the bottom of the pan as the butter melts.
Add the minced garlic to the skillet and sauté, stirring constantly, until fragrant and just starting to turn golden, about 30 seconds, making sure it does not burn.
Pour in the chicken broth and stir in the lemon zest, thyme, rosemary, red pepper flakes if using, and chopped parsley, then bring the mixture to a gentle simmer.
Return the chicken thighs and any accumulated juices to the skillet, nestling them into the lemon herb sauce, and cook at a gentle simmer until the chicken reaches an internal temperature of 165°F and the sauce slightly thickens, about 5 minutes.
Turn off the heat and stir the lemon juice into the sauce, spooning the sauce over the chicken to coat and brighten the flavors without overcooking the lemon.
Drizzle the finished chicken lightly with the extra tablespoon of olive oil if desired, then taste the sauce and adjust with a pinch of additional salt or pepper if needed.
Garnish the chicken with extra chopped parsley and serve hot straight from the skillet with keto-friendly sides such as roasted broccoli, sautéed green beans, or a crisp arugula salad.

Notes

For even better texture, avoid moving the chicken while it sears so a deep golden crust can form. Use an instant-read thermometer to confirm the internal temperature reaches 165°F at the thickest part of each thigh. If you prefer using dried herbs only, substitute 1 teaspoon dried Italian seasoning plus 1/2 teaspoon dried rosemary for the fresh herbs. This dish keeps well for meal prep; cool completely, then store in airtight containers in the refrigerator for up to 4 days or freeze for up to 2 months. Reheat gently in a covered skillet over low heat with a splash of broth to keep the chicken moist.
