How to Make Vegan Chicken Pot Pie Casserole

1. Preheat the Oven

Preheat to 400°F (200°C) and lightly grease a casserole dish.

2. Brown the Plant-Based Protein

Heat olive oil in a large skillet over medium heat. Add soy curls or meatless chicken pieces and cook until lightly browned.

3. Cook the Vegetables

Add onion, carrots, celery, and potatoes. Cook 5–7 minutes until vegetables begin to soften. Stir in garlic and cook for 30 seconds.

4. Make the Roux

Sprinkle flour over the mixture and stir well to coat. Cook for 1 minute to eliminate the raw flour taste.

5. Create the Creamy Sauce

Gradually pour in vegetable broth and non-dairy milk, stirring constantly until thickened.

6. Season and Finish Filling

Add salt, pepper, and thyme. Stir in peas and simmer for 2–3 minutes.

7. Assemble

Transfer filling to the prepared casserole dish. Lay puff pastry over the top, trimming excess and sealing edges.

For a decorative finish, score the pastry lightly with a knife and cut small vents.

8. Bake

Bake 25–30 minutes, until pastry is golden brown and crisp.

9. Rest Before Serving

Allow to rest for 5 minutes so the filling sets slightly before scooping.

Tips for Success

  • If the sauce becomes too thick, add a splash of broth before baking.
  • Keep puff pastry cold until ready to use for maximum flakiness.
  • For extra golden color, brush pastry lightly with non-dairy milk before baking.
  • Don’t skip venting the pastry — it prevents sogginess.
