Old Fashioned Au Gratin Potatoes

Day 51 –  With the “Stay Home. Stay Safe” order extended here until May 28th both kids are searching for what this all means for them. We had the dreaded conversation in our house about school in the fall. Both kids have been questioning what school will look like when they go back in September (or August). Both are having some anxiety over what the world is going to look like as we move into the future. We have to say we really don’t know. There are many options. Not opening the school and keeping the online schooling going – which both were displeased with. A  hybrid of online and in person part-time school or even going back full time in person are all possibilities.  Short of going back full time I don’t think either one will really be happy but we just don’t know. They will adjust but it is going to take time. Like us they are still looking for their “normal.”

For me comfort foods make things feel normal. One of my favorite dishes from when I was a child are Potatoes au Gratin. These cheesy potatoes served with ham were always my go to meal when it was my turn to choose the special dinner. I don’t make them very often but when I do I remember why. These are super tasty and comforting to my soul.

Verdict: I love these potatoes! They are the perfect balance for me of cheese and potatoes. The browned top of the cheesy casserole is my favorite part so I bake them in a full sized 9″ x 13″ pan to get all the cheesy goodness on top I can.  It has been so long since we last made these that we decided they need to go in the rotation again soon they were so good.
