Roque Monsieur

Imagine biting into layers of buttery, crisp toast, rich béchamel sauce, melty cheese, and a luscious egg right on top — that’s what this Roque Monsieur delivers. This air fryer version skips the ham for a pork-free twist, swapping in savory sautéed mushrooms or turkey slices instead. It’s rich, comforting, and so satisfying with every single bite. And the best part? It’s all ready in your air fryer, no flipping or frying needed.

Behind the Recipe

This version of the iconic Roque Monsieur was born out of a craving for that creamy, cheesy French sandwich — but without the ham. I had some fresh mushrooms and leftover béchamel, and the air fryer made the rest of it incredibly simple. The egg-on-top twist turns it into something halfway between breakfast and dinner. Think of it as comfort food with a Parisian soul, minus the pork.

Recipe Origin or Trivia

The Roque Monsieur hails from France and has been a beloved café classic since the early 20th century. Traditionally made with ham and cheese between slices of bread and topped with more cheese or béchamel before baking, it’s France’s elevated version of a grilled cheese. Our pork-free variation stays true to its decadent roots while making it suitable for broader diets. When you add an egg on top, it becomes a Croque Madame — but who’s keeping score when it tastes this good?

Instructions for Making Roque Monsieur

Let’s build this sandwich step by step. It’s fast, fun, and seriously satisfying.

1. Preheat Your Equipment:
Preheat your air fryer to 375°F (190°C) for 3 to 5 minutes.

2. Combine Ingredients:
Make the béchamel by melting butter in a small saucepan. Whisk in flour and cook for 1 minute. Gradually add milk, whisking constantly until thickened. Season with nutmeg, salt, and pepper.

3. Prepare Your Cooking Vessel:
Place a piece of parchment paper in your air fryer basket.

4. Assemble the Dish:
Lightly toast the bread slices in the air fryer for 2 minutes. Then, spread béchamel on one side of each slice. Top four slices with sautéed mushrooms or turkey and a sprinkle of cheese. Cover with another slice, béchamel side in. Add béchamel and cheese on top, then crack one egg over each.

5. Cook to Perfection:
Carefully place the assembled sandwiches in the air fryer. Cook at 375°F (190°C) for 6 to 8 minutes or until the cheese is bubbly and the egg is set.

6. Finishing Touches:
Let cool slightly, then use a spatula to lift out.

7. Serve and Enjoy:
Serve warm with a green salad, fruit, or roasted potatoes.

Texture & Flavor Secrets

Expect crispy edges, creamy layers, and rich, melty cheese in every bite. The egg adds moisture and richness on top while the béchamel gives the sandwich that signature French elegance. The contrast between the crusty bread and the soft, gooey middle is what makes this so irresistible.

Cooking Tips & Tricks

A few simple tweaks can make a big difference:

• Use cold béchamel when assembling so it doesn’t soak the bread too much.
• If using turkey, warm it slightly first.
• Add a sprinkle of chives or herbs on top for extra flavor and color.

What to Avoid

Keep these in mind for best results:

• Don’t overload with cheese — too much can spill and burn.
• Avoid watery fillings — drain mushrooms well before using.
• Don’t skip pre-toasting the bread — it keeps the base crispy.
