Oven-Grilled Roast Beef and Cheddar Sandwiches

These easy oven-grilled roast beef and cheddar sandwiches get a big flavor boost from our creamy horseradish spread. Made from sautéed garlic and shallots, sour cream and horseradish, the spread is a great contrast to the sharp cheddar cheese and tangy sourdough bread. Oven grilling is an easy method that saves time, trouble and dishes because you can make a few sandwiches at a time without needing multiple pans. As long as you keep an eye on them you’ll end up with perfect, evenly toasted sandwiches every time.

A creamy spread made with sauteed garlic, shallots, sour cream and horseradish adds great flavor to these oven-griled roast beef and cheddar sandwiches.


  • 1/2 lb rare deli roast beef, thinly sliced
  • 4 slices sweet onion, 1/4-inch thick
  • 8 thin slices sharp cheddar cheese, sliced
  • 8 slices sourdough bread
  • 2 tablespoons melted butter
  • 1 tablespoon vegetable oil
  • 2 cloves garlic, finely chopped
  • 1 medium shallot, finely chopped
  • 3 tablespoons sour cream
  • 1-1/2 tablespoon prepared horseradish
  • 1 tablespoon mayonnaise
  • Freshly ground black pepper


  • Preheat the oven to 425°F and position a rack in the center.
  • To make the horseradish spread, heat the vegetable oil in a small skillet over medium heat. Add the garlic and shallot and sauté just until the shallot is soft and translucent. Transfer to a small bowl and add the sour cream, horseradish and mayonnaise. Mix well.
  • Place a baking sheet (avoid nonstick) in the oven to preheat while you prepare the sandwiches.
  • Lay 4 slices of bread on a flat surface and spread each piece with about 2 teaspoons of the horseradish mixture. Add a slice of cheese, a slice of onion and several slices of roast beef. Top with the remaining slices of cheese.
  • Spread the rest of the horseradish mixture on the remaining 4 slices of bread and finish the sandwiches. Press down on each lightly, then brush the tops with half of the melted butter.
  • Remove the preheated baking sheet from the oven. Place the sandwiches, buttered side down on the hot sheet. Brush the other side with the remaining butter.
  • Bake for about 8 minutes, until the sandwiches are toasted and golden brown, turning once.
