The holidays are over and it is time to get back to real life. But real life doesn’t have to just be salads, boring, and no fun. It is still cold out, and I still want comfort food. Food that brings me back and makes me feel like I am home. And today we are doing just that with these open faced croque monsieur sandwiches.

A croque monsieur is traditionally a ham and cheese sandwich with mustard that is broiled or fried and brushed with a bechamel sauce. Sounds like pure comfort food to me! But we are putting just a tiny twist on it and making it extra delicious!

I am excited to work with Martin’s on this recipe. Martin’s Old Fashioned Real Butter Bread is exactly what this croque monsieur needs. It is super soft and tender. Plus it combines the nostalgia of classic butter bread with the high quality ingredients we have come to expect today. It is made with 100% real butter, without any other oils. It uses high protein wheat flour, nonfat milk, real cane sugar, and other high-quality ingredients. All the flavors you remember as a kid, but something you feel good about feeding your family.

Martin’s has been baking bread for over 60 years. It has been a staple in so many households for years. Coming together over bread and food, is what creates memories and brings people together. These open faced croque monsieur sandwiches will bring the whole family around the table, and create memories together. The breads gets slightly crispy with the melty cheese, tangy creamy sauce, and the salty ham is just a magical combination!

These sandwiches are super easy to put together. You can get the kids and family in the kitchen to help! Baking in the oven melts the cheese and crisps up the bread. A great weeknight dinner that gets the family together.

We really enjoyed this. We followed the recipe exactly and the sauce had the perfect amount of spice and creamy goodness to the sandwich. We will definitely make this again. Thanks for a great recipe.

I will definitely make this! FYI, I think you meant whisk in the "flour" in the second sentence (not butter). :-)
