French Onion Steak Sandwich Ingredients

Everything you need to make French onion steak sandwiches.

  • Chosen Foods 100% Pure Avocado Oil: Chosen Foods 100% Pure Avocado Oil is ideal for cooking due to its high smoke point and neutral flavor. It enhances the sear on the steak and helps caramelize the onions evenly without burning.

    Chosen Foods Classic Mayo made with 100% Pure Avocado Oil: This creamy, rich mayo with a delicious flavor makes it a versatile ingredient in any recipe, all while the avocado oil provides a source of good fats. In this recipe, it forms the base of the balsamic aioli, enhancing the overall flavor profile and providing a delicious, guilt-free spread.

    Steak: Ribeye and sirloin are both excellent choices for this sandwich, offering rich flavor and tenderness. Ribeye provides a bit more marbling and a juicier bite, while sirloin is leaner and still flavorful. If you prefer, you can substitute these with flank steak or skirt steak, which also has great flavor and texture. Both cuts will cook beautifully and complement the caramelized onions and balsamic aioli.

    Baguette: A crisp baguette provides the perfect crunch and structure for this sandwich. If you need a gluten-free option, substitute with a gluten-free baguette or a sturdy gluten-free bread of your choice. You can also use a ciabatta roll or crusty sourdough as an alternative. These options will still hold up well with the hearty fillings and add a satisfying texture to the sandwich.

Test Kitchen Notes

  • Caramelizing Onions: To achieve the perfect caramelization, cook the onions slowly over medium heat. Stir frequently to ensure they cook evenly without burning. Adding a pinch of cinnamon and a splash of red wine adds depth to the sweetness of the onions, making them an irresistible topping for the steak.

    Balsamic Aioli: The balsamic aioli adds a tangy, creamy element to the sandwich, perfectly balancing the richness of the steak and onions. If you prefer a stronger garlic flavor, consider using a microplane to finely grate the garlic into the mayo.

    Steak Tips: For the best results, use a well-marbled cut like ribeye or sirloin. Season the steak generously with salt and pepper before cooking to enhance its natural flavors. After cooking, let the steak rest for a few minutes before slicing it thinly against the grain; this will ensure tender, juicy slices.

    Baguette Toasting: Toasting the baguette in avocado oil gives it a deliciously crisp texture while preventing it from becoming soggy when assembled. It also adds a subtle flavor that ties the sandwich together.

    Customizing Your Sandwich: Feel free to add more greens like arugula or swap the cheese for your favorite variety. The versatility of this sandwich allows you to make it your own while keeping the core flavors intact.

For the Sandwich

  • 2 tablespoons Chosen Foods 100% Pure Avocado Oil, divided
  • 1/2 pound steak (ribeye or sirloin)
  • Kosher salt, for seasoning the steak
  • Freshly ground black pepper, for seasoning the steak
  • 1 baguette (or gluten-free baguette), cut into two equal lengths and halved lengthwise
  • 4 slices provolone or gruyere cheese
  • Fresh arugula, dressed in balsamic and Chosen Foods 100% Pure Avocado Oil
  • Fresh thyme (optional), for topping

Method

To make the Caramelized Onions:

  • Step 1

    Heat 1 tablespoon of Chosen Foods 100% Pure Avocado Oil in a large skillet over medium heat. Add the sliced onions and cook, stirring frequently, for about 20 minutes, until the onions are soft and beginning to brown.

  • Step 2

    Add the unsalted butter, sugar, kosher salt, and cinnamon to the onions. Continue cooking, stirring every 2-4 minutes, for an additional 20 minutes until the onions are deeply caramelized.

  • Step 3

    Add the chopped garlic and cook for 2 minutes until fragrant. Pour in the red wine, stirring to deglaze the pan. Cook for 2-3 minutes until most of the wine has evaporated. Season with black pepper to taste. Set the caramelized onions aside.

To Prepare the Balsamic Aioli:

  • Step 1

    In a small bowl, whisk together the Chosen Foods Classic Mayo made with 100% Pure Avocado Oil, balsamic vinegar, and the minced garlic. Season with salt and black pepper to taste. Set aside.

Cook the Steak:

  • Step 1

    Heat 1 tablespoon of Chosen Foods 100% Pure Avocado Oil in a skillet over medium-high heat. Season the steak with salt and pepper, then cook for 3-4 minutes on each side, or until it reaches your desired doneness. Let the steak rest for 5 minutes, then slice it thinly against the grain.

Toast the Baguette:

  • Step 1

    Brush the cut sides of the baguette with the remaining tablespoon of Chosen Foods 100% Pure Avocado Oil. Toast in a skillet or under the broiler until golden brown.

Assemble the Sandwiches:

  • Step 1

    Spread the balsamic aioli on the toasted sides of the baguette. Layer the caramelized onions, steak slices, and cheese on the baguette halves. Place the sandwiches under the broiler for 1-2 minutes, until the cheese is melted and bubbly.

  • Step 2

    Top with dressed arugula and fresh thyme if using. Close the sandwiches, slice them in half, and serve immediately.
