Microwave Scalloped Potatoes

READY IN: 40mins
Recipe by Recipe Book Worm

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!)

I love this recipe! I have the microwave cookbook it came out of. At any rate, I make this all the time for holidays to serve with ham. My Changes: DH does not like onion so I leave that out. Also, I'm using my large casserole (2.5 Qt) I use more potatoes and double the sauce except the flour which I use 6T instead of 4. The extra sauce cooks in the Pampered Chef big glass batter bowl without spilling over. However, Cook the casserole on a microwave safe plate because it will boil over. May take 25 minutes to cook through. Makes enough to serve8-10.

Ingredients Nutrition


  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).
