Steak Sandwich with Caramelized Onions and Brie

*By: Linz Bordner*


If you love steak sandwiches, you won’t want to pass this one up. Packed with so many incredible flavor combos such as tender and juicy meat, caramelized onions, creamy Brie cheese, and sweet fig jam, it’s definitely not your average steak sandwich!

We paired the dish with some homemade tater tots, which took some trial and error to get just right. You could also pair with French fries or salad. This meal is both easy and sophisticated and makes for a great lunch, brunch, or even dinner.


  • 2 beef strip steaks or tenderloin (10-ounces each, about 1-inch thick)
  • Kosher salt, for seasoning
  • Ground black pepper, for seasoning
  • 2 ½ tablespoons extra virgin olive oil, divided
  • 2 large red onions, thinly sliced
  • 1 tablespoon Dijon mustard
  • 2 tablespoons melted unsalted butter
  • 8 mini-sized French rolls, or a similar soft, sturdy roll
  • 1 ½ cups arugula
  • 8 ounces Brie cheese, cut into thin slices
  • ½ cup fig jam


1. Preheat the oven to 350°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.

2. Prepare the Dijon onions: Heat 1 tablespoon olive oil in a large sauté 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.

3. 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 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°F. Transfer to a plate and cover with foil. Let rest for 10 minutes, then slice into strips.

4. Spread the melted butter onto the bottom of a 9×13-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.
