Ingredients:
- 1.5 lbs boneless, skinless chicken thighs, cut into 1-inch pieces
- 2.5 lbs Russet potatoes, peeled and cubed
- 1 large yellow onion, finely diced
- 2 medium carrots, peeled and diced
- 2 celery stalks, sliced
- 3 cloves garlic, minced
- 1 cup frozen peas
- 3 tbsp all-purpose flour
- 2 cups low-sodium chicken broth
- 1 tsp Worcestershire sauce
- 4 tbsp unsalted butter
- 0.5 cup whole milk
- 0.5 cup shredded sharp cheddar cheese
- 1 tsp dried thyme
- 0.5 tsp dried rosemary
- 0.5 tsp garlic powder
- Salt to taste
- Black pepper to taste
Instructions:
- Place cubed potatoes in a large stockpot of salted water. Bring to a boil and cook for 15-20 minutes until fork-tender. Drain thoroughly.
- Mash the hot potatoes with 4 tbsp butter, 0.5 cup milk, and garlic powder until fluffy. Set aside.
- In a large skillet or Dutch oven, sear the chicken thigh pieces over medium-high heat until golden brown to develop fond. Remove chicken and set aside.
- In the same skillet, sauté onion, carrots, and celery until softened. Add minced garlic and cook for 1 minute.
- Sprinkle flour over the vegetables, stirring for 2 minutes to cook out the raw flour taste. Slowly whisk in chicken broth and Worcestershire sauce.
- Simmer sauce until thickened. Stir in the seared chicken, frozen peas, thyme, and rosemary. Season with salt and pepper.
- Transfer filling to a 2-quart casserole dish. Spread mashed potatoes over the top, using a fork to create ridges for extra crisping.
- Top with shredded cheddar cheese. Bake at 400°F (200°C) for 20-25 minutes until the potato peaks are golden brown and the gravy is bubbling.
