Mini Croque Monsieur

If you can’t be in France you can still enjoy Mini Croque Monsieur appetizers.  An easy appetizer with puff pastry and a béchamel sauce. Your guests will love this take on a French classic.

Mini croque monsieur appetizers are inspired by an all time favorite French dish, a Croque Monsieur. It’sbasically an open faced ham and cheese sandwich topped with a cheesy béchamel sauce and then placed under the broiler.  Bon appetìt has a recipe that looks fabulous.

The only problem with a true croque monsieur sandwich is that there is a lot of bread and it’s smothered in a cheesy béchamel sauce, maybe not the healthiest of lunches.

If you’re in France and don’t know what to order, you can never go wrong with a croque monsieur, it’s almost always on the menu. While wonderful, it can be a little heavy and requires a knife and fork. These French appetizers, on the other hand, capture the essence but in miniature form.

They are one of my most requested appetizer recipes from my friends and one that I serve over and over again.   You can make mini croque monsieurs in advance and then pop them in the oven before everyone arrives.  

They smell so delicious it’s hard to wait for them to cool.  They are trés bon while hot, but just as good once they’re at room temperature. No utensils necessary, the perfect finger food appetizer.

What you’ll need

With just a few ingredients you’ll be looking for an excuse to make these.

• Puff pastry – the best is one that has butter in the ingredients like Dufour or Trader Joe’s.
• Ham – any type of cooked ham will work. If you don’t have leftovers, get a few slices from the deli.
• Gruyere cheese – It just doesn’t taste like a real croque monsieur without gruyere.
• Mustard– I prefer a whole grain dijon
• Pantry items – flour, butter, milk and an egg.

Which brand of puff pastry should you use?

There are three brands of puff pastry in my area, Pepperidge Farms, Dufour and Trader Joe’s. The difference between them is butter. Dufour and Trader Joe’s uses butter and Pepperidge Farms uses shortening. I prefer Dufour any time I can get it, you can really tell the difference, but you will pay for that difference. Trader Joe’s is almost as good and great on your budget but is only available from October through Deceember.

I’ve used Pepperidge Farms many times and it works for this recipe.  If it’s available and within your budget, I would recommend using Dufour or Trader Joe’s for a more flaky and buttery texture.

Is it hard to make a béchamel sauce:

Absolutely not, and it’s so handy to know how to make one. I use it in my Lasagna, Macaroni and Cheese, Hot Browns and many other recipes. It’s the same technique as you would use to make a roux for Crawfish Etoufee. You start by heating butter and add flour letting it cook until the flour is hot. Next you slowly add milk or if making a roux, some type of broth. It starts out very thick but as you gradually add the liquid it thins out. It needs to cook slowly until it thickens to just the right consistency.

How do you make the best party appetizers:

As fancy as these sound, they’re very simple to make and can be prepared in advance.

Step 1: Start by making the béchamel sauce so that it can cool a little. Melt butter, add flour and then slowly add milk cooking until it has thickened. Then add a little mustard and salt and pepper.

Step 2: Roll out the puff pastry and cut it into into rounds, then top with the béchamel sauce. On top sprinkle chopped ham and gruyere.

I use a 2 inch round biscuit cutter which is a perfect two bite size.  Make sure you chop the ham so that they’re easier to eat. Once they’re assembled, you can refrigerate until ready to bake.

I made these on a night when the girls had gone to a concert and got home rather late with a friend. I figured they might be hungry and want a late night snack. When I got up the next morning there were only a couple left which they quickly ate for breakfast.  I would have heated them a bit, but they swear they were perfect at room temperature.

I’ve made these so many times, they are my go-to appetizer when friends are coming over.

Why are Mini Croque Monsieurs the PERFECT appetizer:

• Easy to prepare
• Can be made ahead of time
• Can be eaten with your fingers, no utensils needed
• They are good warm and at room temperature
• All your guests will love them and want the recipe
