Chicken Shepherd's Pie is the ultimate way to transform leftover chicken and mashed potatoes into a bubbling comfort meal everyone will ask for again. A rich chicken and vegetable filling gets blanketed in buttery potatoes and baked to golden perfection. This cozy main dish is easy to adapt with what you have and hearty enough to feed a crowd.
I first made this when I ran short on time and needed to clean out the fridge. Now, it is the first thing I plan when we have leftover mashed potatoes. My family has even started fighting over the crispy edge pieces.
Ingredients

- Onion powder, mustard powder, thyme and rosemary: add a well-rounded savory earthiness dried herbs work great here
- Ground sage and black pepper: add complexity to the gravy always use fresh ground pepper if you can
- Flour: thickens the filling use all-purpose flour and sift if lumpy
- Half and half: makes the gravy creamy but not too heavy avoid using plant milk here
- Chicken bouillon or better than bouillon: deepens chicken flavor check for low-sodium versions if needed

Step-by-Step Instructions
- Prep the Chicken and Broth:
- Pat the chicken dry and season with salt and black pepper. Add to a saucepan with chicken broth. Bring it slowly to a gentle simmer with the lid slightly ajar. Cook for fifteen minutes or until chicken is just cooked through. Do not let it boil hard or the meat will get tough. Remove the chicken shred with forks and reserve the broth.
- Build the Aromatic Base:
- Melt butter in a wide skillet over medium heat. Add finely diced onion and sauté four minutes until soft and fragrant. Stir in minced garlic and all dried seasonings. Cook gently for one minute to bloom the flavors.
- Create the Roux:
- Sprinkle in flour and stir to coat onion mixture. Keep cooking for two minutes to get rid of raw taste. The mixture will be thick and golden.
- Make the Gravy:
- Turn heat to low. Gradually pour in reserved chicken broth a little at a time stirring in each splash fully before adding more. Add half and half the same way to create a rich smooth gravy. This keeps things thick and lump-free.
- Finish the Filling:
- Stir in chicken bouillon and Worcestershire sauce followed by your shredded chicken. Turn heat to medium and simmer the mixture for ten to fifteen minutes letting the gravy thicken and reduce. Add more chicken broth if it looks tight.
- Add the Vegetables:
- Mix in frozen vegetables and cook until heated through and evenly distributed. Remove skillet from heat.
- Prepare to Bake:
- If your skillet is not oven-safe transfer filling to a greased baking dish. Let filling cool slightly. Gently scoop mashed potatoes over the top in large mounds so you do not disturb the filling. Spread into an even layer with a spatula but do not press down.
- Create a Crispy Top:
- Rake the surface with a fork for texture if you like. Bake uncovered in a preheated oven at four hundred fifty degrees for ten minutes.
- Brown the Potatoes:
- Switch to broil on high for about four minutes to get a golden crispy crust. Watch carefully so nothing burns and avoid glass or Pyrex dishes for this step.
- Rest and Serve:
- Remove from oven. Sprinkle with fresh chopped parsley if you like. Let the pie sit for five minutes before serving so it sets up nicely.

Storage Tips
You can refrigerate leftovers in an airtight container for up to three days. This pie also freezes well for up to three months if wrapped tightly. To reheat let it thaw in the fridge overnight and bake covered in a three hundred fifty degree oven until bubbling.
Ingredient Substitutions
Feel free to swap out chicken thighs for breasts or even use leftover turkey. If you do not have half and half you can stir a splash of whole milk with a bit of cream and get a similar result. Any blend of frozen mixed vegetables will work just pick what your family likes most.
Serving Suggestions
This hearty pie is a meal on its own but a crisp green salad or roasted broccoli on the side keeps things bright. Homemade buttermilk biscuits make it feel extra indulgent and are perfect for scooping up any saucy bits.

Cultural and Historical Context
Shepherd's pie is classically made with lamb but this chicken version has become a soft spot in American kitchens where leftover chicken reigns. Swapping beef or lamb for chicken keeps it a bit lighter while still honoring the comfort food roots.
