🍗 Cheesy Garlic Chicken, Potato & Green Bean Bake

This is a one-pan chicken dinner with juicy seasoned chicken, tender potatoes, green beans, broccoli, and a golden cheesy garlic topping. The combination is similar to popular chicken-potato-green bean bakes, which are commonly prepared as an easy one-pan meal.

🛒 Ingredients

Serves 4–6

Chicken

  • 1½ lb boneless, skinless chicken breasts or thighs
  • 2 tbsp olive oil
  • 2 tbsp melted butter
  • 3 cloves garlic, minced
  • 1 tsp Italian seasoning
  • 1 tsp dried parsley
  • ½ tsp paprika
  • ½ tsp garlic powder
  • ½ tsp onion powder
  • ½ tsp black pepper
  • ½ tsp salt
  • ½ tsp dried oregano
  • ½ cup shredded mozzarella
  • ¼ cup grated Parmesan

Vegetables

  • 3 medium potatoes, cut into small cubes
  • 2 cups fresh green beans, trimmed
  • 1½ cups broccoli florets
  • ½ small onion, sliced
  • 1 tbsp olive oil
  • ½ tsp Italian seasoning
  • Salt and pepper, to taste

👩‍🍳 Instructions

1. Preheat the oven

Preheat oven to 400°F (200°C).

Lightly grease a 9×13-inch baking dish.

2. Prepare the potatoes

Cut the potatoes into small, evenly sized cubes so they cook at the same rate as the chicken.

Toss them with olive oil, Italian seasoning, salt and pepper.

3. Prepare the green beans and broccoli

Add the green beans, broccoli and sliced onion to the baking dish.

Drizzle with a little olive oil and toss gently.

4. Season the chicken

Pat the chicken dry with paper towels.

In a small bowl combine:

  • melted butter
  • olive oil
  • minced garlic
  • Italian seasoning
  • parsley
  • paprika
  • garlic powder
  • onion powder
  • oregano
  • salt
  • black pepper

Rub this mixture generously over both sides of the chicken.

5. Assemble

Arrange the seasoned potatoes, green beans and broccoli around the chicken.

Try to keep everything in a relatively even layer so it roasts rather than steams.

6. Cover and bake

Cover the dish tightly with aluminum foil.

Bake for 30 minutes.

7. Remove the foil

Remove the foil and gently stir the vegetables.

Continue baking for another 15–20 minutes, until the potatoes are tender and the chicken reaches 165°F (74°C) internally.

8. Add the cheese

Sprinkle the mozzarella and Parmesan over the chicken and vegetables.

Return to the oven, uncovered, for another 5–8 minutes, until the cheese is melted and beautifully golden.

For an extra-browned top, broil for 1–2 minutes, watching closely.

9. Rest and serve

Let the casserole rest for 5 minutes before serving.

Spoon the cheesy vegetables onto a plate and place a juicy piece of chicken on top. 😋

  • Boneless chicken thighs will give you especially juicy chicken.
  • For extra flavor, add a squeeze of fresh lemon juice before serving.
