  • 3 cups shredded rotisserie chicken (dark and white meat combined)
  • 2 tablespoons tomato paste
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups chicken broth (low-sodium preferred)
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon dried rosemary, crushed
  • Salt and black pepper to taste

Mashed potato topping

  • 2 pounds russet or Yukon Gold potatoes, peeled and cut into chunks
  • 4 tablespoons butter
  • 1/2 cup milk (more if needed) or half-and-half
  • Salt and pepper to taste
  • 1/4 cup grated Parmesan or sharp cheddar (optional)
  • 1 egg yolk (optional)

Optional garnish

  • Chopped fresh parsley or chives

Equipment

  • 9×9-inch or similar baking dish (or individual ramekins)
  • Large skillet
  • Medium pot for potatoes
  • Potato masher or ricer

Instructions

  1. Preheat oven to 400°F (200°C).
  2. Cook the potatoes: place potato chunks in a pot, cover with cold salted water, bring to a boil, and simmer 12–15 minutes until tender. Drain well.
  3. Make the mashed potatoes: return potatoes to the pot, add butter and milk, mash until smooth. Stir in Parmesan if using, season with salt and pepper, and mix in egg yolk if using. Set aside.
  4. Prepare the filling: heat oil or butter in a large skillet over medium heat. Add onion and carrots; cook 5–7 minutes until softened. Add garlic and cook 30 seconds.
  5. Add tomato paste and stir to coat; cook 1 minute. Sprinkle flour and cook 1–2 minutes.
  6. Gradually stir in chicken broth. Add Worcestershire sauce, thyme, rosemary, and simmer until slightly thickened, 3–4 minutes.
  7. Add shredded chicken, peas, and corn. Stir and heat through. Adjust seasoning. Add a splash of broth if too thick.
  8. Assemble: transfer filling to baking dish. Spoon mashed potatoes over and spread evenly. Add fork texture on top if desired.
  9. Bake 20–25 minutes until golden and bubbling. Broil 2–3 minutes for extra browning.
  10. Rest 5 minutes. Garnish with parsley or chives and serve warm.
