Step-by-Step Instructions
Step 1: Marinate the chicken
In a medium bowl, whisk 3 tbsp lemon juice, 1 tsp lemon zest, minced garlic (4 cloves), 2 tbsp olive oil, Dijon mustard, honey, 1 tsp kosher salt, black pepper, and red pepper flakes (if using). Add the chicken thighs and toss to coat. Let marinate for 15 minutes at room temperature, or cover and refrigerate up to 8 hours. If marinating longer than 30 minutes, remove from the fridge 15 minutes before cooking so the chicken cooks evenly.
Step 2: Make the couscous
Bring 1 cup chicken broth to a boil in a small pot. Stir in 1 tbsp olive oil or butter and 1/4 tsp salt. Place the couscous in a heatproof bowl, pour the hot broth over it, cover tightly, and let stand for 5 minutes. Fluff with a fork, then fold in 1/2 tsp lemon zest and 2 tbsp chopped parsley. Cover loosely to keep warm.
Step 3: Sear the chicken
Heat a large (12-inch) skillet over medium-high heat for 2 minutes. Shake excess marinade from the chicken (do not wipe completely dry) and add the thighs to the hot skillet in a single layer. Cook without moving until deep golden brown, 5–6 minutes. Flip and cook another 4–6 minutes, until the thickest part reaches 165°F. Transfer to a plate and tent loosely with foil to rest.
Step 4: Cook the green beans
Reduce the heat to medium. Add 1 tbsp olive oil to the same skillet, then the green beans. Sauté, tossing, for 3 minutes. Add 2 tbsp water, cover, and steam-sauté until crisp-tender, 2 minutes. Uncover, stir in the remaining 2 cloves minced garlic and 1/2 tsp lemon zest, and cook 30–60 seconds until fragrant. Season with 1/4 tsp salt and a pinch of pepper. Transfer beans to a plate.
Step 5: Build the lemon-garlic pan sauce
Return the skillet to medium heat. Add 1/2 cup broth and 1 tbsp lemon juice, scraping up any browned bits with a wooden spoon. Simmer until reduced by about one-third, 2–3 minutes. Turn off the heat and whisk in the cold butter until the sauce is glossy and slightly thickened.
Step 6: Finish and serve
Return the chicken and any accumulated juices to the skillet, turning to coat in the sauce for 30–60 seconds. Spoon couscous onto plates, add a mound of green beans, and top with chicken. Drizzle with pan sauce and sprinkle with parsley. Serve with lemon wedges for extra brightness.
Pro Tips
- Pat chicken lightly before searing so excess marinade doesn’t burn; a thin coating helps caramelization.
- Use a heavy skillet (cast iron or stainless) and preheat well for best browning.
- Don’t crowd the pan; if needed, sear chicken in two batches for an even crust.
- Add garlic to the beans at the end to prevent it from scorching.
- For ultra-silky sauce, keep butter cold and whisk off heat so it emulsifies cleanly.
Variations
- Swap the veg: Use asparagus or broccolini (same method, adjust time by 1–2 minutes).
- Add briny punch: Stir 1 tbsp drained capers into the sauce with the butter.
- Change the base: Serve with quinoa, orzo, or lemony rice instead of couscous.
Storage & Make-Ahead
Refrigerate leftovers in airtight containers for up to 4 days. Reheat chicken and beans gently in a skillet with a splash of broth or water until warmed through; or microwave in 45-second bursts, stirring sauce between bursts. Cooked couscous keeps well for 4 days; fluff with a fork and warm covered with a damp paper towel. Marinate chicken up to 8 hours ahead. Trim beans up to 2 days in advance and store wrapped in a paper towel in a zip-top bag.
