Start by trimming the chicken breasts and slicing the zucchini into half-moons. I like to pat the chicken dry with a paper towel to help it brown better. Mixing the zucchini with a little olive oil and seasoning ensures every bite is flavorful.
In a small bowl, combine olive oil, garlic, oregano, paprika, salt, and pepper. Rub the mixture over the chicken breasts evenly. Toss the zucchini in any leftover seasoning to ensure everything is coated for even flavor.
Place the chicken in the center of the baking sheet and arrange the zucchini slices around it. This helps the chicken cook evenly while the zucchini roasts to a tender-crisp texture. I like giving the veggies a little space so they don’t steam and lose their crunch.
Bake at 400°F (200°C) for 25–30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C). I like to check the zucchini halfway through to make sure it doesn’t overcook. The chicken should be golden and slightly crispy on top.
Once out of the oven, squeeze fresh lemon juice over the chicken and zucchini. Garnish with chopped parsley for freshness. I find this step really elevates the flavors and makes the dish look restaurant-worthy.
