Ingredients for the Panera Bread Steak & White Cheddar Panini
This sandwich is made from ingredients you are going to find at your local grocery store. You will need some ciabatta bread, sliced roast beef from the deli, pickled red onions, white cheddar cheese, and some horseradish sauce.
You can use a panini press, or you can use a griddle pan, and a heavyweight to help press the sandwich down.
How to make pickled red onions
Pickled red onions take almost 2 minutes to make, and they can be used in oh so many ways. You can enjoy these as a side with grilled meats, on sandwiches, or even in the place of pickles.
I like to slice my onions on a mandolin, but you can use a knife to slice a red onion super thin. Then you will need some vinegar, water, and spices. You literally combine all of these and let them rest for about 15 minutes before you serve them. They taste better with age, so you may even want to keep these on hand all of the time.

Panera Bread Steak & White Cheddar Panini
Pickled Red Onions
- 1 cup sliced red onions slice thin
- 1/2 cup white vinegar
- 1 tablespoon sugar
- 1 1/2 teaspoons salt
- 1 cup warm water
- 1 loaf ciabatta bread
- 2 tablespoons pickled red onions
- 2 tablespoons horseradish sauce
- 6 ounces sliced roast beef
- 4 slices white Cheddar cheese

Pickled White Onions
- Slice onions as thin as possible, I like to use the 1/8 inch setting on my mandolin. Place the onions in a glass jar. In a small bowl combine white vinegar, sugar, salt, and warm water. Stir until the sugar and salt are dissolved. Pour liquid into the jar with onions. These should rest about 30 minutes for using.
- Split the ciabatta loaf open, spread the horseradish sauce onto the top inside of the split loaf. Add roast beef to the bottom. Add the pickled onions, and cheese.
- Place the sandwich in the press, and cook about 3 minutes or until the sandwich is heated through.
- Heat the Panini press. If you do not have a panini press you may want to use a grill pan, and a heavy object to press the sandwich into the pan. Some people like to wrap a brick with foil and use this as a press.
