Turn your steak leftovers into pure comfort with this Leftover Ribeye Steak and Gouda Grilled Cheese Sandwich. Tender slices of ribeye, smoky Gouda, caramelized onions, and a touch of Dijon mustard come together between crispy, buttery bread for an indulgent twist on a classic favorite.
Ingredients
- 1 cup thinly sliced leftover ribeye steak
- 1 small onion, thinly sliced
- 4 slices Gouda cheese
- 4 slices hearty bread (sourdough or rustic white)
- 2 tsp Dijon mustard
- 2 tbsp butter, divided
- Salt and pepper, to taste
Instructions
- Caramelize the onions: In a skillet over medium heat, melt 1 tablespoon of butter. Add sliced onions and cook slowly for 10–15 minutes, stirring occasionally, until golden and sweet. Set aside.
- Warm the steak: In the same skillet, add the leftover ribeye slices and warm gently for 1–2 minutes. Remove from heat.
- Assemble the sandwich: Spread a thin layer of Dijon mustard on one side of each bread slice. Layer Gouda cheese, ribeye slices, and caramelized onions on one slice of bread, then top with the second slice.
- Grill the sandwich: Melt remaining butter in a clean skillet over medium heat. Add the sandwich and cook until the bread is golden and crispy, about 3 minutes per side, pressing gently with a spatula.
- Serve: Slice in half and serve immediately while the cheese is gooey and the steak is warm.
Serving Suggestion
Pair with a side of tomato bisque or a crisp green salad for a cozy and satisfying meal.
