- Onion: Use yellow onions for sweetness; sauté until translucent for maximum flavor.
- Garlic: Fresh garlic cloves enhance the aroma; don’t skimp on this aromatic superstar!
- Chicken Broth: Low-sodium broth helps control salt levels while keeping everything moist and flavorful.
- Flour: A key element for thickening your sauce; all-purpose flour works well here.
- Puff Pastry Sheets: These create that irresistible flaky crust everyone loves—don’t forget to thaw them!
- Olive Oil: A drizzle adds flavor during sautéing; go for extra virgin for a richer taste.

How to Make Chicken & Spinach Pot Pie Casserole with Feta
Preheat Your Oven and Prepare Your Dish: Start by preheating your oven to 400°F (200°C). Spray a baking dish with nonstick cooking spray or grease it lightly with butter to prevent sticking.
Sauté the Aromatics: In a large skillet over medium heat, add olive oil and toss in the diced onion and minced garlic. Sauté until onions turn translucent and release their sweet aroma—about 4-5 minutes.
Add the Chicken: Stir in diced boneless chicken breasts seasoned with salt and pepper. Cook until they are browned on all sides—about 6-8 minutes—ensuring they’re cooked through.
Add Spinach and Feta: Toss in fresh spinach leaves and crumbled feta cheese. Stir until the spinach wilts down—this should take around 2-3 minutes—and everything is well combined.
Create the Sauce: Sprinkle flour over the mixture while stirring constantly to combine evenly. Gradually pour in chicken broth while continuing to stir until everything thickens—about 3-4 minutes should do it.
Assemble Your Casserole: Pour your delightful chicken-spinach mixture into your prepared baking dish. Roll out thawed puff pastry sheets over the top, sealing any edges or gaps.
Bake Until Golden Brown: Place your casserole in the preheated oven and bake for 25-30 minutes or until puff pastry turns golden brown and crispy.
And there you have it! A delightful Chicken & Spinach Pot Pie Casserole with Feta that’s sure to impress not just your taste buds but also anyone lucky enough to share this meal with you. Enjoy!
