Preheat your oven to 400°F (200°C) and let it come to full temperature while you prepare the filling.
02 -
In a large skillet over medium heat, cook the chopped onion and jalapeños until they're soft and fragrant, about 5 minutes. The onions should be translucent.
03 -
Stir in the pulled brisket, corn, peas, beef broth, garlic powder, and thyme. Season with salt and pepper, then mix everything together well.
04 -
Let the mixture simmer for about 10 minutes, stirring occasionally, until the flavors meld together and some of the liquid reduces.
05 -
Transfer the hot brisket mixture to a standard pie dish. Unroll the pie crust and lay it over the filling, trimming and crimping the edges to seal it up nice and tight.
06 -
Cut several slits or a decorative pattern in the top crust to let steam escape. Bake for 25-30 minutes until the crust is beautifully golden brown.
07 -
Let it cool for at least 5 minutes before cutting - the filling will be molten hot! Slice and serve while still warm.
