Traditionally, the croque-monsieur consists of toasted bread filled with ham and cheese and topped with Béchamel Sauce. In my plant-based version, I use eggplants, red bell peppers instead, all covered in a cheesy Mornay sauce. 🧀
How to Prepare The Vegetables?
Simple, yet super indulgent, I’m a big fan of fried eggplants! I also add red bell peppers for a bright, sweet flavor. 🍆🫑
First, I salt the sliced eggplants to take advantage of the osmosis reaction, preventing them from becoming chewy. After resting for 15 minutes, I fry them in extra virgin olive oil on both sides. Once done, I put them aside and use the same pan to sauté the bell peppers until they are sweetened and less bitter.
How to Prepare the Mornay Sauce?
The Mornay Sauce is a cheesy variation of the classic béchamel sauce. I make it by adding nutritional yeast and apple cider vinegar. I love how cheesy this sauce is, it’s also perfect for mac and cheese!
Start by warming some olive oil in a pan and stir in flour. Whisk it for a few minutes to cook off the floury taste, then slowly pour in unsweetened milk. Mix in nutritional yeast and apple cider vinegar, and season with salt, pepper, and a pinch of nutmeg. That's it!

Cooking and Assembling
Prepare by slicing bread for the croque-monsieur. Spread sauce on both top and bottom slices. On the latter, layer the eggplants and bell peppers as well. Bake at 200°C (390°F) for 10 minutes until the bread is crunchy.
Traditionally, croque-monsieur is served with French fries and a side salad in bistros. I enjoy pairing it with a simple green salad, adding any leftover eggplants and bell peppers.
Variations of Croque-Monsieur
Croque-Monsieur might be the most famous type of this Parisian sandwich, but there are many variations in France!
The most popular variation is the Croque-Madame, topped with an egg, but there are many others:
- Croque Provençale (with tomatoes)
- Croque Normand (with apples)
- Croque Tartiflette (with potatoes)
- The Sweet Croque (with banana and chocolate powder)
There are so many ways to make Croque-Monsieur! That’s my cue to you to experiment 🧑🍳
Try different vegetables and sauces. It may not strictly be a Croque-Monsieur, but your taste buds will love it just the same!
