Note: You can make this a one pot dish by using a 12" Cast Iron Skillet, or you can also transfer the filling to a 9x13" Casserole Dish as well. Both work great!
I recommend browning your vegan chick'n in the pan first and then setting aside, but this is totally optional!
Next melt the vegan butter in your skillet and then add in the carrots, celery and shallots / onion. Stir to get them all nice and coated and cook down for about 8 minutes or until they begin to soften a bit.
Add in the rosemary sprig and bay leaves, chopped thyme and sage, a pinch of salt and black pepper, mushroom seasoning and then add in the minced garlic. Stir around and cook for 1-2 minutes.
Stir in the flour. I recommend doing this a tablespoon or so at time and stirring in, and then adding in more flour once it's combined. Repeat this process until all the flour is mixed in.
Next do the same with the vegan chicken broth, add a little and combine. Start with 2 cups of veggie broth. Repeat this with the non-dairy milk.
Add in the reserved vegan chick'n, stir to combine and then add in the frozen peas and stir to combine those as well.
If it seems too thick, add up to 1 more cup of veggie broth as needed. Taste and adjust for seasoning! Very important! Keep warm on low while we prepare the puff pastry. To achieve the flower pattern, cut one sheet of the puff pastry into rectangular strips. For the middle part, use the other sheet and then place a bowl on top and cut out around the bowl.
Before you add the puff pastry remember to remove the Rosemary sprig and bay leaves!
Assemble the puff pastry pedals first. Lay them so they are overlapping slightly and lightly press them into each other. I also recommend pressing a bit of a lip up the wall of the skillet to seal it. Add the middle circle part and lightly press down into the pedals. Cut a small crisscross section in the middle to allow steam to vent.
Brush the puff pastry with a vegan egg such as Just egg, or some aquafaba, non-dairy milk or melted vegan butter.
Bake in a preheated 425° F oven for 25 - 30 minutes. Check around the 20 minute mark to make sure it doesn't burn, and then checking every 1 -2 minutes to avoid a burned crust. If you are making the single serve version, check the puff pastry after 15 minutes.
Once it's baked to perfection, remove from the oven and let it rest a minimum of 15 minutes. Not only will it be incredibly too hot to eat, but the filling will need time to cool down and set.
ENJOY!
