Warm, comforting, and endlessly adaptable, this Chicken Shepherd’s Pie is a cozy way to use leftover rotisserie chicken or a rotisserie substitute. It layers a savory chicken-and-vegetable filling under a blanket of mashed potatoes and bakes until the top is golden and slightly crisp — perfect for weeknight dinners, potlucks, and picky eaters who love a familiar mash-and-filling combo. If you prefer a pastry crust instead of mash, consider a classic chicken pot pie recipe for a different take on the same flavors.

Why you’ll love this dish

This pie hits several marks at once: it’s budget-friendly, kid-approved, and fast when you use leftover chicken and store-bought mashed potatoes. The shredded chicken keeps the filling light while the mashed-potato topping adds comfort and texture. It’s also forgiving — swap vegetables or herbs depending on what’s in your fridge.

“Family-friendly weeknight comfort: the kids ask for seconds and I love how fast it comes together.” — a happy home cook

Perfect occasions: weeknight dinners, casual entertaining, or a make-ahead option for busy nights. It’s also a great way to turn rotisserie chicken into a new meal.

How this recipe comes together

This is a simple three-part process: sauté aromatics, combine with shredded chicken and peas/carrots/corn plus a splash of chicken broth, then top with mashed potatoes and bake. Total hands-on time is short — mostly chopping and stirring — and the oven does the rest for a golden finish.

What you’ll need

2 cups shredded cooked chicken (leftover rotisserie chicken works great)
4 cups mashed potatoes (homemade or store-bought)
1 cup frozen mixed vegetables (peas, carrots, corn — choose your favorites)
1 medium onion, chopped
2 garlic cloves, minced
1 cup chicken broth (low-sodium if preferred)
1 tbsp olive oil
Salt and pepper to taste
1 tsp thyme (fresh or dried)
1 tsp rosemary (fresh or dried)

Substitutions/notes:

Swap turkey for chicken if you have holiday leftovers.
Use a splash of cream or a tablespoon of butter in the mashed potatoes for extra richness.
If you prefer a thicker filling, stir a teaspoon of cornstarch into the broth before simmering.

Step-by-step instructions

Preheat the oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish (or similar size).
Heat 1 tablespoon olive oil in a skillet over medium heat. Add the chopped onion and sauté until translucent, about 4–5 minutes. Add the minced garlic and cook 30–45 seconds until fragrant.
Stir in the shredded chicken and frozen mixed vegetables. Add the chicken broth, thyme, rosemary, salt, and pepper. Mix well. Simmer gently for about 5 minutes so the flavors meld and most of the liquid reduces. If the filling seems watery, simmer a minute longer or add a small slurry of cornstarch and water.
Spread the chicken-vegetable mixture evenly in the prepared baking dish. Smooth it into an even layer.
Dollop or spread mashed potatoes over the filling until covered in a uniform layer. Use a fork to create light peaks on the potato surface for extra browning. Dot with a little butter if you like a crisp, golden crust.
Bake in the preheated oven for 25–30 minutes, until the potato topping is golden and slightly crispy around the edges. If you want more color, finish under the broiler for 1–2 minutes — watch closely to avoid burning.
Let cool for a few minutes before serving so the filling sets slightly and is easier to portion.

How to plate and pair

Serve slices straight from the dish for a rustic presentation or scoop onto plates with a spatula for clean portions. Crisped potato peaks add visual appeal. Pair with a bright side salad (vinaigrette cuts through the richness) or roasted green beans for a textural contrast. For a spoonable, stew-like companion, compare this pie to 30-minute chicken and dumplings biscuits to see how the textures differ and choose what your dinner crowd prefers.

Storage and reheating tips

Refrigeration: Cool to room temperature, cover tightly, and store in the refrigerator for up to 3–4 days.
Freezing: Assemble in a freezer-safe dish and freeze unbaked for up to 2 months. Thaw overnight in the fridge before baking. Baked leftovers can be frozen for 2–3 months; wrap tightly with foil and plastic.
Reheating: From the fridge, reheat individual portions in the microwave (cover and heat until steaming through, stirring once) or place the whole dish in a 350°F (175°C) oven for 15–20 minutes until heated to 165°F (74°C) internal temperature. For a crisp top, finish under the broiler for 1–2 minutes.

Food safety note: Because cooked chicken is the main protein, always reheat until the filling reaches 165°F (74°C) and refrigerate within two hours of cooking to reduce bacterial risk.

Pro chef tips

Crispier top: Brush mashed potatoes with melted butter before baking and create ridges with a fork to increase surface area for browning.
Texture control: If you prefer a creamier filling, stir 2–3 tablespoons of cream or cream cheese into the chicken mixture. For a thicker filling, add a cornstarch slurry (1 tsp cornstarch + 1 tbsp cold water).
Herb freshness: If using fresh thyme and rosemary, chop finely and add half during cooking and half just before baking to keep bright herb notes.
Make it ahead: Assemble the pie, cover, and refrigerate for up to 24 hours before baking — great for dinner timing. Let sit at room temperature 15–20 minutes before baking to avoid dramatic temperature shock to the dish.

Recipe variations

Cheddar-topped: Mix 1 cup shredded sharp cheddar into the mashed potatoes or sprinkle on top before baking for a cheesy crust.
Low-carb: Replace mashed potatoes with mashed cauliflower for a lighter, lower-carb topping.
Vegetarian: Swap shredded chicken for a mix of sautéed mushrooms and lentils, and use vegetable broth.
Mediterranean twist: Add olives, sun-dried tomatoes, and oregano; top with a Parmesan mash.
Spicy kick: Stir in a teaspoon of smoked paprika or a pinch of cayenne to the filling for warmth.

Common questions

Q: Can I use raw chicken instead of shredded rotisserie chicken?
A: Yes, but you’ll need to cook the chicken first. Cut into small pieces, sauté with the onions until cooked through, or poach until done, then shred. Ensure the filling reaches 165°F (74°C) during final bake.

Q: Can I make this entirely ahead of time and freeze it?
A: Yes. Assemble the unbaked pie in a freezer-safe dish, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge and bake as directed, adding a few extra minutes if still slightly cold.

Q: How do I get the top extra-crispy without drying out the filling?
A: Bake until nearly done, then switch to the broiler for 1–2 minutes to brown the tops of the mashed potatoes. Keep the dish a few inches below the broiler and watch constantly to avoid burning.

Q: Is this recipe kid-friendly and freezer-friendly?
A: Absolutely. Mild flavors and familiar textures make it kid-friendly. It also freezes and reheats well, making it ideal for lunchboxes or meal prep.

Q: Can I use instant mashed potatoes?
A: Yes — instant or refrigerated mashed potatoes both work. If using instant, prepare them slightly thicker than usual to prevent a watery top.
