Chicken
- 2 cups cooked, shredded or diced chicken (rotisserie chicken works well)
Vegetables
- 1 cup diced carrots
- 1 cup diced celery
- 1 cup diced onions
- 1 cup peas (frozen or fresh)
Cream Sauce
- 4 tablespoons butter
- 1/4 cup all-purpose flour (or gluten-free flour for GF version)
- 2 cups milk (dairy or plant-based such as almond or oat milk)
- Salt and pepper to taste
- 1 teaspoon fresh or dried thyme
Herbs
- 1 tablespoon fresh parsley (chopped) or 1 teaspoon dried parsley
Topping
- 1 sheet pie crust or puff pastry (regular or gluten-free)
- 1 beaten egg (for brushing the crust)
- Prepare the Chicken and Vegetables: Cook chicken by boiling or roasting if not pre-cooked, then dice or shred it. Sauté diced carrots, celery, and onions in butter over medium heat until tender but still slightly crisp to maintain texture and natural sweetness.
- Make the Creamy Sauce: In a saucepan, melt the butter and whisk in the flour to form a roux. Slowly add milk while whisking constantly to avoid lumps. Cook the mixture until it thickens into a creamy sauce, then season with salt, pepper, and thyme.
- Combine Ingredients: Stir the cooked chicken, sautéed vegetables, and peas into the cream sauce, mixing thoroughly to coat everything evenly and create a smooth, creamy filling.
- Add the Topping: Transfer the filling into a casserole dish. Cover it evenly with your choice of pie crust or puff pastry. Trim excess dough, flute the edges, and brush the top with beaten egg for a golden, glossy finish.
- Bake to Perfection: Preheat the oven to 375°F (190°C). Bake the casserole for 30 to 35 minutes, or until the crust turns golden brown and the filling bubbles around the edges. Let rest 5-10 minutes before serving to set the casserole.
Notes
- Use shredded rotisserie chicken for quicker preparation without sacrificing flavor.
- Sauté vegetables just until tender-crisp to retain texture in the final bake.
- Whisk continuously when making the roux and adding milk to prevent lumps in the sauce.
- Chill pie crust or pastry dough before baking to ensure a flaky, crisp topping.
- Let the casserole rest before serving for neat slicing and better cohesion.
