Globe Au Gratin Potatoes
Need to bring potatoes to a gathering? You have just found your new, go to dish for “fancy” potatoes. I usually reserve making them for the holidays, bringing to a gathering or a very special dinner because they are a bit decadent. Irresistibly delicious and always a big hit, but definitely rich.
This is an adaption from a recipe I found in the Boston Globe (hence the name), over thirty years ago! I have tweaked it a bit over the years, using different cheeses, swapping half and half for the original light cream and always had great luck. Give it a try, use your favorite cheese; use light cream, half and half or milk, but whichever you choose, I promise you will not be disappointed.
INGREDIENTS
5 lbs. potatoes, yukon gold or russet (see notes below)
8 Tbs. butter, divided
6 Tbs. flour
1 tsp. dry mustard
3 cups light cream or half & half
1 tsp. kosher salt
3/4 tsp. fresh ground pepper
1 cup grated, extra sharp cheddar (see notes below)
1/2 cup panko bread crumbs
DIRECTIONS
Preheat oven to 350º
Peel potatoes and boil until almost tender. Drain, cut into bite-sized pieces and put in a greased casserole dish.
While the potatoes are cooking, melt 6 Tbs.of the butter in a sauce pan on medium heat, add the flour, mustard, salt & pepper, stir and cook for a minute or two, until slightly browned. You’re just cooking the raw taste out of the flour here. Then, slowly add the 3 cups of half and half, cook, stirring frequently until the sauce starts to thicken. Pour over the potatoes, then sprinkle the cheese on top of that.


Finally, melt the remaining 2 Tbs. of butter, pour over the bread crumbs, season with salt and pepper, and mix well. Sprinkle the bread crumbs over the potatoes. Either bake immediately in a preheated oven for about 20-30 minutes, until it is bubbly and browned. Or, you could refrigerate until ready to bake and there is no problem doing that a day ahead. However, if you do refrigerate the dish, then make sure to bring it to room temperature, before baking, otherwise increase the baking time.
NOTES
Although you can use russet or Yukon gold potatoes, I think the Yukons hold up a bit better. They are definitely my new favorite, as they keep there shape better, even if overcooked a bit. The russets, when overcooked a bit (which I seem to do too frequently), can breakdown and tend to get a bit mushy. They still taste delicious, they’re just not as firm.
I highly recommend getting a block of cheese and grating it, rather than buying a bag of grated. The pre-grated versions have additives to lengthen the shelf life and it doesn’t melt as well.
