Easy Microwave Scalloped Potatoes

This came from a recipe book given to me by my grandmother-in-law. I like it because it cooks in about 1/2 the time of regular (oven) scalloped potatoes, and tastes basically the same. Great for weeknights when time is at a premium, or if you have no room in the oven. (Note, I noticed other recipes for scalloped potatoes call for cheese or other ingredients - this is scalloped potatoes like my mom used to make, basically just white sauce and potatoes. We always eat ours with lots of ketchup on top!)

• Ready In: 40 mins
• Serves: 4-6

Ingredients

• 3  tablespoons margarine or 3  tablespoons butter
• 2  tablespoons flour
• 2  cups milk
• 1  teaspoon salt
• 1⁄4 teaspoon pepper
• 4 -6  medium potatoes, sliced
• 1  small onion, sliced

Directions

1. Put margarine (or butter) into LARGE glass bowl, and microwave on High for 1 minute, or until melted. (If you really like cleaning your microwave, feel free to use a smaller bowl.).
2. Blend in flour, salt & pepper. Gradually stir in milk.
3. Microwave on High 8-10 minutes, stirring after 4 minutes.
4. Layer half the potatoes and onion in a greased 2-quart casserole dish. Top with half the prepared sauce, then the rest of the potatoes and onion, then the rest of the sauce.
5. Cover and microwave on High 20 minutes, or until done. (Cooking times will depend on the strength of your microwave; I think ours is in the 1,200-watt range, and 20 minutes usually works just fine for us).
