Pat dry the chicken breasts and slice into 1-inch strips. Season generously with salt and pepper.
Heat a large skillet over medium-high heat and add a tablespoon of olive oil until shimmering and fragrant.
Place the chicken strips in the hot skillet in a single layer. Sear for about 3-4 minutes on each side, until golden brown and cooked through, hearing a satisfying sizzle and seeing a caramelized crust form.
Remove the cooked chicken and set aside. Add another tablespoon of olive oil if needed, then toss in the diced zucchini.
Sauté the zucchini for 5-7 minutes, stirring occasionally, until it’s tender and has developed some golden edges.
Add the minced garlic to the zucchini and cook for 30 seconds until fragrant, with a slightly nutty aroma filling the air.
Return the browned chicken to the skillet, nestling it among the zucchini slices. Reduce the heat to low, cover, and cook for another 2-3 minutes to let the flavors meld.
Squeeze fresh lemon juice over the skillet contents, then sprinkle with chopped herbs for a bright, fresh finish. Toss gently to combine.
Give everything a final stir, then remove from heat. Let it rest for a couple of minutes to allow juices to settle.
Serve the skillet straight from the pan for a rustic presentation, enjoying the tender chicken and caramelized zucchini with a squeeze of lemon and fresh herbs on top.
