Dough: Whisk yeast and ¼ cup warm water in a large bowl until yeast is dissolved. Whisk in oil, sugar, salt, and 1¼ cups room-temperature water. Add 4 cups (500 g) flour and stir with a wooden spoon until a shaggy dough forms.
Turn dough out onto a clean surface and knead to bring together and incorporate any loose flour. Continue to knead, dusting with more flour as needed to prevent sticking, until the dough is very smooth and firm and no longer sticky, 10–12 minutes. Gather dough into a ball, dust with more flour, and place in a clean large bowl. Cover with a damp towel. Let the dough sit in a warm draft-free spot until doubled in size, about 1½ hours.
Meanwhile, place butter on a large sheet of parchment paper and sprinkle Parmesan, garlic powder, onion powder, oregano, pepper, and paprika on top; toss butter to coat. Place in a pile on 1 side of parchment. Fold opposite side of parchment over; lightly beat with a rolling pin in several directions until butter is pliable and forms into a single mass (it should still be cold and have a waxy texture, not soft and greasy looking). Unfold parchment and use a small offset spatula or butter knife to spread butter into about a 7" square. Fold parchment back over butter, this time enclosing it in a neat square packet like you’re wrapping a present. Place packet seam side down, then roll over it with the rolling pin to smooth butter into an even layer and work into corners of packet. Chill until dough is ready.
Turn dough out onto surface and punch down with your fist to deflate. Place on a rimmed baking sheet lined with a sheet of plastic wrap and stretch into about a 9" square, flattening it with the heel of your hand. Cover with another sheet of plastic wrap and freeze until dough is very firm but not frozen solid, 10–15 minutes.
Remove dough from freezer and transfer to a lightly floured surface. Remove butter from refrigerator and unwrap. Place butter on top of dough, arranging in the center at a 45° angle so it looks like a diamond set inside the square of dough. Fold dough corners up and over butter so they join in the center. Pinch along the seams to seal. You should now have a square of dough completely encasing the butter.
Dust underneath and on top of dough with more flour, then roll out into a long, even slab that’s about 3 times longer than it is wide, keeping the ends as square as possible. Fold slab from short ends into thirds like a letter to form a square packet, then rotate the dough 90-degrees and roll out again to the same dimensions. Try to work quickly to prevent butter from softening and making dough sticky and hard to roll (if this happens, chill dough about 10 minutes before proceeding). Fold in thirds again, then wrap in plastic and chill until dough is very firm, at least 2 hours and up to 1 day.
Filling: Arrange a rack in middle of oven; preheat to 350°. Line a small rimmed baking sheet with parchment paper and pour marinara onto sheet; spread into a single layer. Bake, stirring with a heatproof rubber spatula every 15 minutes, until sauce is thickened, darker in color, and starting to blacken around the edges, 45–60 minutes. Reduce oven temperature to 300° and continue to cook, stirring every 15 minutes, until sauce holds its shape and is the consistency of tomato paste, 45–60 minutes more. Let cool.
Meanwhile, toss pepperoni, soppressata, mozzarella, Parmesan, oregano, and red pepper flakes in a large bowl to combine. Add reduced tomato sauce and mix well to evenly distribute. Taste filling. It probably doesn’t need salt, but add a pinch if you think it does.
Using a kitchen scale, measure out filling into 60 g portions. Press each portion between your hands (wear gloves if you have them) to form tightly compacted 4x1" rectangles. Place portions on a large plate or a rimmed baking sheet and chill, uncovered, until ready to assemble hot pockets.
Do Ahead: Filling can be made 4 days ahead. Cover and keep chilled.
Seasoning Mix and Assembly: Toss breadcrumbs, salt, onion powder, paprika, and cayenne in a small bowl to combine; set aside.
Roll out chilled dough on a lightly floured surface to a large ¼"-thick slab a little more than 22x11", dusting underneath and on top with more flour as needed. Using a knife or pizza cutter, cut into a sharp even 22x11" rectangle, then cut rectangle in half lengthwise. Cut each half crosswise in fourths to make eight 6x5½" rectangles.
Working with 1 square at a time, lightly floured work surface and thin out and elongate both longer sides of dough with rolling pin, leaving about a thicker 1½" wide strip in the center. Place a portion of filling on thicker part, then brush thinner sides with a thin layer of egg white. Trim the thinner edges to make them straight, if needed, then fold them up and over the filling, overlapping as much as possible. Trim away all but about 1½" excess dough on shorter sides, then pinch them firmly together to seal. Fold shorter sides up and over like a burrito. Place on a parchment-lined baking sheet, seam side down. Once you have finished assembling all of the hot pockets, make sure they are evenly spaced out on the baking sheet and cover with a damp towel. Let sit at room temperature until slightly puffed, 15–25 minutes.
Meanwhile, preheat oven to 300°.
Uncover hot pockets and brush all over with remaining egg white. Sprinkle with reserved breadcrumb mixture and cut four ½"-long vents in the surface of each one, spacing evenly. Bake until hot pockets are puffed and golden brown all over and illing is lightly bubbling, 30–35 minutes. Let cool before serving.
Do Ahead: Hot pockets can be made 2 days ahead. Store tightly wrapped at room temperature.
