Make Ahead Philly Beef Strata Recipes

Steps:

• Place a third of the bread cubes in a greased 13x9-in. baking dish. Layer with a third of the peppers, onion, roast beef and cheese. Repeat layers twice. In a large bowl, whisk the eggs, milk, mustard, salt and pepper; pour over top. Cover and refrigerate for 8 hours or overnight., Remove from the refrigerator 30 minutes before baking. Bake, covered, at 325° for 1 hour. Uncover; bake 15-20 minutes longer or until a knife inserted in the center comes out clean. Let stand for 10 minutes before serving.

Steps:

• Preheat the oven to 350 degrees F.
• Tear the hoagie rolls into medium bite-sized pieces and spread on a baking sheet. Toast in the oven until dried out, 10 to 15 minutes.
• Brown the steak slices in the oil, breaking up into pieces with a wooden spoon, in a cast-iron or nonstick skillet over medium-high heat. Remove from the skillet and drain all but 1 tablespoon of fat. Cook the onion, peppers, mushrooms, a pinch of salt and some pepper, stirring occasionally, until soft and translucent, 4 to 5 minutes. Add the steak back to the pan, stir well, turn off the heat and set aside.
• Microwave the cheese sauce in 30-second intervals, stirring after each, until pourable. Pour into a large bowl with the eggs and half-and-half and whisk to combine well.
• Place a layer of dried bread in a deep 9-by-13-inch casserole dish. Add a layer of steak and peppers, then ladle the cheese custard over until just covered. Repeat until all the ingredients are used. Bake the strata until just set, 30 to 35 minutes.
• Preheat the broiler to low. Layer the provolone across the top of the pan, overlapping as necessary. Broil until the cheese topping is brown and bubbly, 5 to 10 minutes. Let the strata sit for 10 minutes to set before serving.

Steps:

• In a 12-inch skillet, cook beef, onions and garlic over medium-high heat, stirring frequently; drain. Reduce heat, cook 5 more minutes. Cool for 5 minutes.

• Freeze about 1 hour, stirring once, until firm.
