Preheat your oven to 400F. This temperature is perfect for roasting and will help achieve that beautiful golden color.
Line a small sheet pan with foil and set it aside. This not only makes for easy cleanup but also helps in roasting.
In a small bowl, combine all the ingredients for the marinade: olive oil, garlic, oregano, basil, black pepper, and salt. Whisk them together until well blended. This marinade is where the magic happens, so don’t skip this step!
On the sheet pan, place the cubed chicken, potatoes, string beans, onion, and tomatoes. Ensure they’re evenly spread out to allow for even roasting.
Pour the marinade mixture over the veggies and chicken. Use your hands to mix everything together, ensuring each piece is fully coated. This is crucial for flavor!
Place the sheet pan in the preheated oven and bake for 25 minutes. As it cooks, your kitchen will fill with an irresistible aroma.
Check for doneness by ensuring the potatoes are tender and the chicken is cooked through. You want a lovely char on the veggies, which adds depth to the dish.
Once satisfied, remove from the oven. Let it sit for a couple of minutes before serving to enhance the flavors.
Serve with your choice of rice, pasta, or a light salad. This meal is versatile and pairs well with many sides!
