Potato Bake with Onions in a Béchamel sauce

Creamy goodness oozing with cheese, that is what this potato bake is all about! Well worth the time it takes to prepare.

In our opinion, potatoes are delicious in every form, and lucky for us they have so many! These versatile vegetables can be enjoyed as fries, hash-browns, mashed, baked, and roasted. But a clear winner of the potato show off is definitely THE potato bake! This dish is a Potato Bake in a delectably rich and creamy Béchamel sauce, and ticks all of the classic potato bake boxes! 

The Elements of a Great Potato Bake 

This potato bake is alternating layers of onion, slices of potato, and béchamel sauce. The layers are topped with mozzarella cheese and baked in the oven for one hour and ten minutes, or until the potatoes are fork tender (a fork should pierce through them easily). If you are short on time, you can parboil your potatoes so that they need less time in the oven!  

What is a Béchamel Sauce?  

Béchamel sauce has been around for hundreds of years, with many different opinions as to where it came from. Some believe it originated in France and was brought to Italy in the 1500s, whereas others believe it only came to be in the 1700s when it was invented by Louis de Béchameil, a chief steward to King Louis XIV. All we know is, we are glad it came to be! A Béchamel sauce is a staple sauce made from three simple ingredients- butter, flour, and milk (you would probably already have these in your kitchen!). Many herbs and spices are added and play a major role in the flavor of the sauce. A tip when making the sauce is to keep stirring– this will ensure a smooth sauce that is free from lumps.  

Serve this potato bake with roast chicken or steak, and a salad of your choice for a balanced and delicious weeknight meal!
