Best French Onion Steak Sandwiches Recipes

ULTIMATE STEAK SANDWICH

Steps:

• Preheat an oven to 500 degrees F (260 degrees C). Split the rolls open and toast them on a baking sheet in the oven while it is preheating. Mix together the mayonnaise, garlic, and Parmesan cheese in a small bowl. Refrigerate until ready to use. Remove the rolls from the oven when toasted as desired.
• Heat olive oil in a large skillet over medium-high heat. Carefully place the sliced steak and onions in the pan and season with sea salt, Worcestershire sauce, and liquid smoke. Cook and stir until the steak is browned and the onion is tender, about 10 minutes.
• Generously spread the prepared garlic-Parmesan mayonnaise on both halves of the toasted rolls. Divide the steak and onion mixture evenly among the bottom halves of the rolls, piling them high. Top each with 2 slices provolone cheese and sprinkle with Italian seasoning. Place the tops on the sandwiches.
• Bake the sandwiches on a baking sheet in the preheated oven until the cheese is melted, about 5 minutes.

FRENCH DIP STEAK SANDWICHES WITH HORSERADISH SAUCE

Steps:

• For the horseradish sauce: Combine the sour cream, horseradish, salt and pepper in a medium bowl. Cover and refrigerate to develop the flavors.
• For the au jus: Combine the onion soup, beef broth, sugar, Worcestershire sauce, salt and 3/4 cold water in a saucepan and bring to a boil over medium-high heat.
• Reduce heat and simmer 5 minutes. Taste and season with pepper and more salt if needed. Strain the mixture and discard the onions (if there were any in the soup.) Cover and keep warm.
• For the steak: Heat a grill or grill pan over high heat. Oil the grill pan if needed. Season the steak with salt and lots of black pepper. Grill the steak for 2 to 3 minutes per side for medium rare. Let the steak rest, then thinly slice.
• Spread the horseradish sauce on one side of each baguette. Dip the steak slices in the warm au jus and place on top of the bread with horseradish sauce, then place the other slices of bread on top. Transfer the remaining au jus to two dipping bowls and serve with the sandwiches for dipping.

STEAK SANDWICH WITH CARAMELIZED ONIONS AND BRIE

Steps:

• Preheat the oven to 350 degrees F. Remove steak from the refrigerator and place on a plate. Season liberally with salt and pepper on both sides. Let come to room temperature while you caramelize the onions.
• Prepare the Dijon onions: Heat 1 tablespoon olive oil in a large sautee pan over medium high. Add the sliced red onions and 1/4 teaspoon kosher salt. Cook until the onions begin to soften and brown, 5-8 minutes. Reduce heat to low and let cook, stirring occasionally, until the onions are very soft and caramelized, about 15 additional minutes. Remove from heat and stir in the Dijon to evenly coat. Remove the onions to a plate or bowl, then gently wipe the skillet clean with a paper towel.
• Heat the remaining 1 1/2 tablespoons olive oil in the skillet over medium high. Once the oil is very hot and almost smoking, add the seasoned steaks. Do not crowd them-if your skillet is not large enough to easily accommodate both, cook them in batches. Sear the steaks for 1 minute on each side, then reduce the heat to low and cook the steak for about 6-8 minutes, turning once, until rare and a thermometer inserted in the center reaches 125 degrees F. Transfer to a plate and cover with foil. Let rest for 10 minutes, then slice into strips.
• Spread the melted butter onto the bottom of a 9x13-inch baking dish, using just enough to coat the pan. Lay the bottom of the buns in a single layer in the baking dish, then top with the arugula, steak slices, Brie, and the caramelized onions. Spread the inside of the top buns with about 2 teaspoons jam, then lay the buns on top to complete the sandwiches. Brush the bun tops with the remaining melted butter, then cover the pan with foil. Bake for 15 minutes, just until the cheese has melted. Transfer to a serving plate and enjoy warm.

FRENCH ONION SANDWICHES

Steps:

• In a large skillet, melt butter or oleo. Add steaks and cook over medium high heat for 2-3 minutes on each side or till done. Remove from skillet, reserving the drippings. Cook the onion in the drippings until tender. Combine the broth, cornstarch, Worcestershire sauce, garlic powder, and a dash of pepper. Add to skillet. Cook until bubbly. Cook and stir 2 minutes more. Place on toasted bread top with swiss and onion mixture.

FRENCH ONION DIP SANDWICHES (SLOW COOKER)

Steps:

• Heat 3 tablespoons olive oil over medium heat in a large, deep pot. Add onions and toss to coat with oil. Cook, stirring often, until softened, about 15 minutes. Add 1 tablespoon butter. Cook and stir until onions start to brown, about 15 minutes more.
• Stir sugar and 1/2 teaspoon salt into the onions in the pot. Continue to cook, stirring once halfway through, until onions are well-browned, 10 to 15 minutes more. Mix in garlic and cook for 1 minute more.
• Stir 3 tablespoons of water into the pot, scraping bits from the bottom. Let simmer for 3 minutes; repeat with an additional 3 tablespoons water. Simmer for 3 minutes more and repeat. Add vermouth; scrape bits from the bottom and sides of the pot. Cook for 4 minutes more. Add stock, Worcestershire sauce, soy sauce, thyme, and bay leaf. Simmer for 10 minutes; do not boil. Add black pepper. Discard bay leaf. Remove pot from heat and allow soup to cool. Pour into the slow cooker, but don't turn it on.
• Trim any excess fat from the rump roast. Sprinkle all sides with salt and pepper. Heat remaining 2 tablespoons olive oil in the pot over high heat. Cook the meat, holding it down with tongs, until browned on all sides, about 10 minutes. Transfer meat carefully to the slow cooker. Spoon the soup over the meat so that it is topped with a few onions. Cover and cook on Low for 4 hours.
• Remove meat from the slow cooker. Slice it diagonally and return slices to the slow cooker. Continue to cook on Low for 2 hours more.
• Preheat the oven to 350 degrees F (175 degrees C). Spread rolls with remaining 2 tablespoons butter; place face-down on a baking sheet.
• Bake rolls in the preheated oven until beginning to brown, 8 to 10 minutes. Remove from the oven, flip, and sprinkle with Gruyere cheese. Set oven rack about 6 inches from the heat source and turn on the oven's broiler. Broil rolls until cheese is slightly bubbly and lightly browned, 2 to 4 minutes.
• Remove meat from the slow cooker using a slotted spoon. Place on the rolls. Serve soup on the side for dipping.

FRENCH ONION GRILLED CHEESE

Steps:

• In a large skillet over medium-high heat, melt 2 tablespoons butter. Add the onions and season with salt and pepper. Cover and cook, stirring once or twice, until the onions are softened, 3 to 5 minutes. Uncover, reduce the heat to medium-low, and cook, stirring occasionally, until deep golden brown, 20 to 25 minutes. If the onions look dry or like they might burn, add a few tablespoons of water at a time, scraping up any browned bits that are stuck to the bottom of the skillet. If desired, once the onions are done, deglaze the skillet with vinegar and cook until the liquid has evaporated, about 1 minute. Transfer the onions to a medium bowl and season to taste with salt and pepper. Wipe out the skillet, or wash it, if necessary.
• Add the cheese to the onions and stir to combine. Put down two slices of bread, and scoop half of the cheese-onion mixture onto each one. Top with the remaining slices of bread, and press down gently.
• In the skillet, melt 1 tablespoon butter over medium heat. Add the sandwiches and cook until the bottoms turn golden brown, 3 to 4 minutes, reducing the heat to prevent toast from darkening too quickly, if needed. Add the remaining 1 tablespoon butter, flip the sandwiches, press down and cook until the cheese has fully melted and the bottoms turn golden brown, 3 to 4 minutes. Serve immediately.

SLOW-COOKER FRENCH ONION SHREDDED BEEF SANDWICHES

Steps:

• Spray 5-quart slow cooker with cooking spray. Trim excess fat from beef. Rub beef with steak seasoning and salt. In 12-inch skillet, heat oil over medium-high heat. Cook beef in oil 2 to 3 minutes on two sides, until browned. Transfer to slow cooker.
• In large bowl, beat melted butter, tomato paste and mustard with whisk. Stir in brown sugar. Stir in onion and garlic; pour over beef. Cover and cook on Low heat setting 8 to 10 hours or until beef is tender.
• Remove beef to cutting board; let stand 5 to 10 minutes or until cool enough to handle. Meanwhile, in small bowl, mix cornstarch and vinegar. Stir into liquid in slow cooker; cover and cook on High heat setting 5 to 10 minutes or until mixture thickens. Shred beef; return to cooker.
• Position oven rack 4 inches from broiling element. Set oven control to broil. Place buns, split sides up, on large cookie sheet. Divide cheese evenly among bun tops. Broil 1 to 3 minutes or until buns are toasted and cheese melts. Divide beef mixture evenly among bun bottoms. Sprinkle with parsley, then top with bun tops.
