I grew up loving those nasty boxes of Au Gratin potatoes with the dried potato slices and the powdered cheese mix. In all honesty, I *still* love them.
But I knew in order to be considered an Actual Grown Up, I should learn how to make them myself. So I did. And they are GOOD! And so blissfully easy. I used a recipe that takes 90 minutes, but you can parboil the potatoes whole and then slice them up if you want to save time.
Homemade Au Gratin Potatoes:
4-5 Yukon Gold potatoes (I peel mine, but the original recipe said it didn't matter)
1 medium sized sweet yellow onion
3 tbs butter
3 tbs flour
2 cups milk
1.5-2 cups shredded cheddar cheese
1/2 tsp garlic powder
Preheat oven to 450. Slice the potatoes into thin chips, and slice up the onion. Layer the potatoes and onion in an oven-safe pyrex/casserole dish. On medium-low heat, melt the butter, then stir in the flour. Slowly add the milk while stirring. Add the garlic powder and some salt and pepper, then start adding in the shredded cheese. After all the cheese is melted, pour it into the casserole dish.
This should result:
It looks tasty already! And I haven't even cooked it!
Then I cover the top with foil and bake for 90 minutes. Usually with 20 minutes left I'll stir it all up and uncover so it gets a nice brown crusty top.
I made this with the chicken tenders I wrote about a bit ago. And steamed asparagus, as well. You will notice the green vegetables to fat/carbs ratio is set on "morbidly obese", but that's how I roll.
