Is there anything better than an ooey, gooey, cheesy and decadent grilled cheese? We didn't think so. This childhood favorite got a serious makeover with this recipe, so don't expect to see Kraft singles. This grilled cheese is made with perfectly cooked flank steak, vintage white cheddar cheese and a homemade horseradish cream sauce. Each bite is filled with gooey melted cheese and spicy horseradish. Trust me, these babies are worth all the calories.

One of these will instantly warm up your cold, tired bones after a long day shoveling snow (or in our case, long day watching our husbands shovel snow). Plus, they could make fabulous cocktail party appetizers if you cut them into bite-size pieces! After one bite of these, you'll never eat a regular grilled cheese again.

Steak & horseradish cream grilled cheese

Serves 4


For the sandwich: 

  • 1 pound flank steak
  • 8 slices ciabatta bread
  • 8 tablespoons of butter
  • 4 slices vintage cheddar cheese
  • 4 tablespoons horseradish cream (recipe below)
  • 2 medium yellow onions, sliced
  • 1-1/2 tablespoon olive oil
  • 1 cup sliced mushrooms

For the horseradish cream: 

  • 1/2 cup sour cream
  • 2 tablespoons freshly grated horseradish
  • 1/2 tablespoon Dijon mustard
  • 1/2 teaspoon white wine vinegar
  • Salt and pepper


  1. Heat the olive oil in a large skillet over medium heat. Add the onions and cook until softening, about 2 minutes. Add the mushrooms and cook another 10 to 15 minutes, or until the vegetables are fully cooked and the onions are golden brown.
  2. Liberally season the steak with salt and pepper. Using the same pan you did for the onions and mushrooms, add the steak and another 1/2 tablespoon of olive oil. Cook the steak until browned on both sides and rare in the middle, about 3 minutes on each side. Let sit for about 5 minutes and then slice into strips.
  3. Butter the sourdough bread on both sides. Layer the steak, onions, mushrooms and cheese on one piece of bread. Slather the 1 tablespoon of horseradish cream on the other piece of the bread and press down.
  4. Grill each sandwich on a panini press for about 1 to 3 minutes, or until the cheese is melted and oozing out.
