So I did a little searching on line, looking for fairly simple potatoes au gratin or something similar. I ended up combining a few recipes, adapting for what we had on hand, and using a shortcut I found. The results were not at all bad, although this has made us resolve to keep better cheese on hand. I used mostly a colby/cheddar mix we had on hand, intended for dressing up tacos and nachos and the like, but this would be just divine with a really sharp cheddar! We will also add chives and/or leeks next time.
Ingredients:
- 4-6 russet potatoes, peeled and sliced--a food processor makes this incredibly easy (ours varied greatly in size, so I just used up the rest of what we had in one bag)
- Salt and pepper to taste
- 3 Tbsp butter
- 3 Tbsp flour (I used Pamela's Baking and Pancake mix, which works really well)
- 2 cups milk
- 2 cups cheese
Steps:
- Preheat oven to 400 degrees Fahrenheit (about 200 Celsius).
- Place sliced potatoes in a glass casserole dish. Add some salt and pepper as you do this.
- Microwave potatoes for about 8 minutes--this will cut the baking time down greatly!
- Make white sauce: melt butter in a saucepan over medium-low heat and then add flour. Be sure to get the flour fully stirred in and cooked. (NB: since the Pamela's mix includes some baking powder, it will bubble a bit when you first add it, but it's otherwise just like using regular flour.)
- Add milk and stir frequently until thick. My little white sauce trick is to get the mixture up to a low boil and let it stay there for about a minute. This gets it to just about the right thickness a little faster, but you have to be careful not to burn the mixture!
- Either turn off the heat or put it as low as possible and add the cheese. Stir until smooth. You can add salt if you want.
- Pour cheese mixture over potatoes.
- Bake for about 30 minutes. The top should be just a little brown.
