One-Pan Garlic Parmesan Chicken and Green Beans

One-pan garlic parmesan chicken and green beans is a flavorful, easy dinner that brings tender chicken, crisp-tender vegetables, and a savory Parmesan coating together on one sheet pan. Because everything cooks at once, cleanup stays simple while dinner comes together quickly.

Why This One-Pan Garlic Parmesan Chicken and Green Beans Works

This recipe works because the chicken and green beans roast together, allowing their flavors to blend. In addition, garlic, Parmesan, Italian seasoning, and olive oil create a golden, savory coating without a complicated sauce. As a result, you get a satisfying meal with minimal prep and only one pan to wash.

Ingredients

4 boneless, skinless chicken breasts, about 6 ounces each
1 pound fresh green beans, trimmed
3 tablespoons olive oil, divided
4 garlic cloves, minced
1/2 cup finely grated Parmesan cheese
1 teaspoon Italian seasoning
1/2 teaspoon paprika
1/2 teaspoon kosher salt
1/4 teaspoon black pepper
1 tablespoon fresh lemon juice
Optional: chopped parsley and extra Parmesan for serving

How to Make Garlic Parmesan Chicken and Green Beans

First, preheat the oven to 425°F. Line a large rimmed sheet pan with parchment paper or lightly coat it with cooking spray.
Next, pat the chicken dry. Then, place it on one side of the pan and brush it with 1 tablespoon of olive oil.
In a bowl, combine the remaining olive oil, garlic, Parmesan, Italian seasoning, paprika, salt, and pepper. Stir until a thick mixture forms.
Spread the garlic Parmesan mixture over the chicken. Meanwhile, toss the green beans with the lemon juice and a little of the remaining seasoning mixture.
Arrange the green beans beside the chicken in a single layer. Therefore, avoid overcrowding the pan so everything roasts instead of steams.
Bake for 20 to 25 minutes, or until the chicken reaches 165°F in the thickest part and the green beans are tender.
Finally, rest the chicken for 5 minutes. Garnish with parsley and extra Parmesan, then serve warm.

Pro Tips

Use chicken breasts with a similar thickness so they finish at the same time.
For especially thick breasts, pound them gently to an even thickness before seasoning.
Check doneness with an instant-read thermometer rather than relying only on cooking time.
For extra browning, broil the pan for 1 to 2 minutes at the end, watching carefully.
Although fresh green beans are best here, you can use trimmed frozen green beans without thawing them first.

Storage Instructions

Cool leftovers completely, then place them in an airtight container and refrigerate for up to 3 days. Reheat gently in a covered skillet or in the microwave until hot. However, avoid overcooking the chicken, since reheating it too long can make it dry. For longer storage, freeze the chicken and green beans for up to 2 months, then thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use chicken thighs?

Yes. Boneless, skinless chicken thighs work well and stay juicy. Nevertheless, cook them until they reach 165°F internally.

Can I add other vegetables?

Absolutely. Broccoli florets, zucchini, or sliced bell peppers are good options. Cut larger vegetables into small pieces so they cook evenly with the chicken.

How do I keep the Parmesan from burning?

Use finely grated Parmesan and bake the pan on the center rack. If the topping browns too quickly, loosely cover the chicken with foil for the remaining cooking time.

Can I prepare this meal ahead of time?

Yes. Mix the seasoning, trim the green beans, and store both separately in the refrigerator for up to 24 hours. Then assemble the pan just before baking.
