My husband's birthday was a couple of weeks ago. All he wanted for his birthday was scalloped potatoes, pork chops and red velvet cake (I make Non-Red Velvet Cake because I don't use red food coloring, but it doesn't change the taste of the cake). He LOVES potatoes and he loves cheese, so scalloped potatoes are his favorite. Through the years I have tried several different recipes and they were all okay, but a few years ago I used Pioneer Woman's recipe and now that is the ONLY recipe I use. I don't even like potatoes very much, but these are amazing! WARNING - THEY ARE NOT CALORIE FREE! But they are so worth splurging on for special occasions. I don't know what the difference is between scalloped and au gratin, but we just call them scalloped.
Here is a link to Pioneer Woman's recipe
Of course, I change it up a little to add the flavors that my family likes so here's how I do it:
2 tablespoons butter, softened
4 large russet OR 8 red potatoes
1/2 cup 2% milk
1 1/2 cups heavy cream
2 tablespoons flour
3 tablespoons minced garlic
1 onion, diced
1 teaspoon salt
2 tablespoons McCormick Hot Shot or pepper
1 tablespoon chopped basil
1 cup shredded sharp cheddar
1 cup shredded monterey jack
Option - cooked & chopped ham or bacon are great additions
Preheat oven to 400 degrees.
Slice potatoes into circles or diced cubes. I use red potatoes because they are less starchy and have lots of iron, so since they are smaller, I just slice them in circles.
Combine milk and cream in bowl.
Add the flour, garlic, salt, pepper (Hot Shot), basil and onion. Whisk together well so that the flour is incorporated into the mixture.
Grease square baking dish with the softened butter. Pour potatoes into dish. Pour mixture over potatoes.
Cover the dish with foil and bake it for 30 minutes. Remove the foil and bake for 20 minutes more. Sprinkle the cheese all over the top and bake 5-10 minutes more or until cheese is bubbly.
TIPS FOR A BUSY WEEKNIGHT - I got these all ready in the morning before I left for work, covered with foil and put in refrigerator. Kevin gets home an hour before I do, so he took the dish and set it on the counter to get to room temperature and turned the oven on. Then all I had to do when I got home from work was pop the dish in the oven and let them bake while I cooked the pork chops. I think these could be cooked in a rectangular slow cooker also. I haven't tried it yet.
Merry Christmas to you all!
