This easy stromboli recipe takes a few shortcuts from the grocery store so you can have dinner on the table fast. Refrigerated roast beef au jus provides the base for the filling alongside sweet caramelized onions. Thyme and pepperoncini peppers add some sharp notes to balance out the savory meat and onions. Purchased pizza dough forms the crust of this beef stromboli recipe. The characteristic rolled bread creates several crunchy bread layers within each bite. Its flavor and variety make it a great game day snack or party grab-and-go dish, but the heartiness of the beef and onions still make it perfect for a nice sit-down meal. Ingredients 1 Tbsp. butter 1 large sweet onion, thinly sliced 1 tsp. chopped fresh thyme ¼ tsp. salt ¼ tsp. black pepper 2 tsp. olive oil 1 Tbsp. cornmeal 1 pound pizza dough, purchased or homemade 1 15-oz pkg. refrigerated cooked beef roast au jus ¾ cup shredded mozzarella cheese (6 oz.) ¾ cup shredded smoked Gouda cheese (6 oz.) 1/3 cup sliced pepperoncini peppers 1 egg yolk Directions For caramelized onions, in a 10-inch skillet melt butter over medium. Add onion, thyme, salt, and pepper; cook, covered, stirring occasionally, until onion is tender, 13 to 15 minutes. Uncover; cook, stirring occasionally, until onion is golden, 4 to 6 minutes more. Meanwhile, preheat oven to 375°F. Line a 15×10-inch baking pan with foil. Brush with olive oil and sprinkle with cornmeal. On a lightly floured surface roll dough to a 13×10-inch rectangle. Transfer to prepared pan. Heat beef roast au jus according to package directions. Remove meat from the au jus and shred. Reserve au jus for serving; keep warm. Arrange shredded beef on dough, leaving a 1/2-inch border. Sprinkle with half of the cheeses. Top with the caramelized onions and pepperoncini peppers. Top with the remaining cheeses. Starting from a long side, roll up dough around filling. Pinch seam and ends to seal. Lightly beat egg yolk with 1 tsp. water. Brush dough with egg yolk mixture. Using a sharp knife, cut shallow slits on top to vent. Bake until golden brown, 30 to 40 minutes. Cool 10 minutes. Cut into slices. Serve with reserved au jus.
