Ingredients
Cheese Sauce
- 1 cup leftover gravy
- 1/2 cup milk
- Pinch of nutmeg
- 2 cups shredded Gruyère cheese, divided
- 1/2 cup grated Parmesan cheese
Sandwich
- 4 croissants, halved
- 4 tablespoons Dijon mustard
- 1 cup leftover mashed potatoes
- 1 cup leftover turkey
- 1 cup leftover cranberry sauce
- 1/2 cup leftover vegetables
- 4–8 slices crispy bacon
For Serving
- 4 fried eggs
- Crispy sage leaves
Instructions
- Make the cheese sauce: In a small pot, combine the leftover gravy and milk. Bring to a gentle boil over medium heat. Add a pinch of nutmeg for warmth and aroma. Remove from heat and stir in 1 cup of shredded Gruyère cheese and the grated Parmesan until fully melted and smooth.
- Prepare for baking: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper. Arrange the bottom halves of the croissants evenly on the sheet.
- Assemble the sandwiches: Spread 1 tablespoon of Dijon mustard on each bottom croissant half. Layer a generous spoonful of mashed potatoes over the mustard. Drizzle some of the cheese sauce on top of the potatoes, then add turkey, cranberry sauce, leftover vegetables, and crispy bacon slices. Top with the croissant halves. Spoon the remaining cheese sauce over the sandwich tops, then sprinkle with the remaining Gruyère cheese.
- Bake the sandwiches: Place the assembled croque madames in the preheated oven. Bake for approximately 3–4 minutes or until the cheese sauce is bubbling and has a nice golden-brown color.
- Fry the eggs: While the sandwiches are baking, fry the eggs sunny-side up or to your preferred doneness in a skillet over medium heat, aiming for runny yolks to complement the richness of the sandwiches.
- Serve: Remove the croque madames from the oven. Place one fried egg atop each sandwich. Garnish with crispy sage leaves for a fresh, aromatic finish. Serve immediately and enjoy your elevated Thanksgiving leftovers!
