Preheat oven to 400°F. Grab a 9-inch deep-dish pie plate or 8×8 baking dish.
In a large skillet over medium heat, melt 3 tbsp butter. Sauté celery, carrot, onion, and garlic for 5–6 minutes until softened and fragrant.
Add broccoli (or your chosen low-carb veggies) and cook 2 more minutes.
Pour in broth and heavy cream. Stir in poultry seasoning, thyme, salt, and pepper.
Sprinkle xanthan gum over the surface and whisk like a wizard until the sauce thickens (2–3 minutes).
Fold in the shredded turkey, remove from heat, and set your creamy potion aside.
In a food processor (or by hand), pulse almond flour, coconut flour, baking powder, and salt. Add cold butter cubes and pulse until crumbly. Add sour cream and egg; pulse until dough forms. Chill 10 minutes if you like (makes handling easier).
Press ⅔ of the dough into the bottom and up the sides of your dish (no rolling pin required!). Pour in the creamy turkey filling.
Roll or pat the remaining dough between parchment and cut into strips for a beautiful lattice (or crumble it on for a rustic cobbler top).
Brush with egg wash for that legendary golden shine.
Bake 25–30 minutes until the crust is deep golden and the filling bubbles like a victory cauldron.
Rest 10 minutes, scatter fresh parsley, and serve steaming slices of pure comfort!
