A Michigan pasty wraps seasoned beef, potatoes, rutabaga, and onions in a flaky pastry crust. This protein-rich, portable family meal originated with Upper Peninsula miners and remains a beloved regional classic.
Combine the diced beef, potatoes, rutabaga, and onion in a large mixing bowl. Season the mixture with kosher salt and black pepper, stirring gently to distribute evenly.
In a separate bowl, cut the cold unsalted butter into the all-purpose flour with a pastry cutter or fingertips until the mixture resembles coarse crumbs. Add ice water gradually, mixing until the dough just comes together without overworking.
Divide pastry dough into four equal pieces. Roll each piece into a circle about 8 inches wide on a lightly floured surface, ensuring consistent thickness for even baking.
Place a generous portion of the beef and vegetable filling onto one side of each pastry circle, leaving a rim for sealing. Fold the dough over, press edges together firmly, and crimp or tuck to seal. Brush each pasty with beaten egg for a golden finish.
Arrange pasties on a parchment-lined baking sheet and bake at 400°F for 45–50 minutes. Rotate halfway through baking for even browning. Bake until the crust is deeply golden and filling is tender. Let cool slightly before serving.
