Here’s my recipe for oven-baked croque-monsieurs with béchamel sauce—they’re easy to make. It’s a classic family favorite that’s sure to be a hit with kids and adults alike!

As you’ll see, making these croque-monsieurs is really very simple. Basically, you toast the slices of bread until they’re golden and crispy. At the same time, you prepare the béchamel sauce. Put everything in a baking dish and pop it in the oven 😉

Serve these croque-monsieurs with a seasonal salad, and you’ve got a complete meal, with meat, vegetables, and carbs… It’s a pretty rich dish, but it’s so good 😋

Enjoy, and thank you in advance for your comments 🙏
