Ingredients for Your Lemon Chicken

• Extra virgin olive oil

How to Make Lemon Chicken

Step 1. In a large bowl, whisk together 3 tablespoons of olive oil, 2 tablespoons of fresh lemon juice, the oregano, and minced garlic until well combined. Season with salt and black pepper to taste, then give everything a good stir. Set the marinade aside while you prepare the remaining ingredients.

Step 2. Add the cubed chicken to a large bowl and pour half of the prepared marinade over top. Toss until the chicken is evenly coated, then set it aside to soak up the flavor while you move on to the next step.

Step 3. Add the sliced zucchini and yellow squash to the bowl with the remaining marinade. Toss until the vegetables are evenly coated, then set them aside while you cook the chicken.

Step 4. Heat a large nonstick skillet over medium heat. Once the skillet is warm, add the remaining tablespoon of olive oil and the sliced red onion. Season with salt and black pepper to taste, then stir to coat. Cook for 4–5 minutes, stirring occasionally, until the onion softens and begins to turn lightly golden around the edges.

Step 5. Add the marinated chicken to the hot skillet and cook for 8–10 minutes, stirring occasionally, until the chicken is golden brown and fully cooked. Transfer the chicken and onions to a plate or serving platter and set aside while you cook the vegetables.

Step 6. Increase the heat to medium-high and add the zucchini and yellow squash to the skillet. If you’d like, season with a little extra salt and black pepper. Cook for 3–5 minutes, stirring occasionally, until the vegetables are crisp-tender and lightly browned.

Step 7. Return the chicken, onions, and any juices back to the skillet, then stir everything together until well combined. Remove the skillet from the heat and drizzle with the remaining fresh lemon juice. Sprinkle with chopped parsley and fresh basil for a burst of flavor and color. Serve right away with extra lemon wedges on the side if desired, and enjoy!
