Let’s Make it together
Prepare Your Ingredients: Gather all your ingredients before starting to ensure a smooth cooking process. Slice the onions thinly while your rolls warm in the oven for added crunch.
Sauté Those Onions: In a skillet over medium heat, melt some butter and add your sliced onions. Cook until they turn golden brown and smell divine—about 15 minutes should do it!
Heat Up Your Roast Beef: To infuse moisture, gently heat your roast beef in a separate skillet over low heat. You want it warm but not dried out; around five minutes should suffice.
Melt That Cheese!: Place slices of cheese atop the warm roast beef in the skillet. Once melted (which should take only a couple of minutes), remove from heat and prepare for assembly.
Assemble Your Sandwiches: Take those crispy rolls from the oven and layer on the warm roast beef with melted cheese. Top with sautéed onions and a drizzle of horseradish sauce for an extra zing!
Dunk Away!: Serve each sandwich with a small bowl of au jus on the side for dipping. Trust me; every bite deserves that savory dunk!
Enjoy every juicy bite of your homemade roast beef sandwich! It’s an experience that brings joy—not just to your taste buds but also to your heart.
