Philly Cheese Steak Spaghetti Recipe 455

Steps:

• Put the steak in the freezer for 30 minutes to firm up for easier slicing.
• Preheat the oven to 400 degrees F. Bring a pot of salted water to a boil.
• Slice the steak as thinly as possible, discarding any large pieces of fat; set aside.
• Cook the pasta according to the package instructions for 1 minute less than al dente. Drain, then transfer to a large bowl; set aside.
• Heat 1 tablespoon of the oil in a large skillet over high heat until shimmering. Working in batches, add the beef in a single layer, season with 1 teaspoon salt and several grinds of pepper and cook without stirring, until brown on the bottom, about 3 minutes. Flip the beef with tongs and brown the other side, about 3 minutes. Transfer to the bowl with the pasta.
• Heat 1 tablespoon oil in the same skillet over medium heat and add the onions. Season with 1 teaspoon salt and several grinds of pepper. Cook, stirring often, until translucent and softened but not brown, about 10 minutes. Transfer to the bowl with the pasta.
• Heat the remaining 1 tablespoon oil in the same skillet over medium heat and add the peppers. Season with 1 teaspoon salt and several grinds of pepper. Cook, stirring often, until softened but not brown, about 10 minutes. Set aside.
• Add the sour cream, beef broth, 3/4 cup of the sharp provolone, the diced mild provolone and 1 teaspoon salt to the pasta bowl and stir to combine. Transfer to a 9-by-13-inch baking dish and cover with the remaining mild provolone slices. Top with the bell peppers and pickled cherry peppers.
• Bake until the mixture is starting to bubble around the edges and the cheese is melted on top, about 30 minutes. Top with the remaining 3/4 cup sharp provolone and bake until heated through and the top is slightly golden, about 10 minutes. Let sit for 5 minutes before serving so the pasta can absorb some of the liquid and the cheese can set.
