Bacon and Cheddar Scalloped Potatoes

I can't really figure out where my inspiration comes from, but fortunately for Diane and me, it just comes. Don't interpret this to mean that Diane isn't good at cooking because she is. I enjoy many of the meals that she prepares. It just so happens that right now, I do more of the cooking (since I am the man-wife who works from home while she goes to school all day).
Anyway, I was trying to think of something delicious to make with what we had in stock (you have no idea how many times we run to the grocery store in order to have the exact ingredients for a recipe). We had purchased some red potatoes a while back and it was about time we made something starchy since we neglected them for so long. I wasn't up for the usual mashed potatoes or grilled potatoes with rosemary, so I decided to make scalloped potatoes.
Normal scalloped potatoes are good, but I think many things can be easily improved by adding a little cheddar and bacon. I went to my favorite online recipe site, AllRecipes.com, and quickly search for a simple (yet delicious) scalloped potato recipe. I found one recipe that fared well in the reviews.

Ingredients (Serves 4)
3-1/4 large potatoes, peeled and thinly sliced
1/2 cup chopped onion
2 tablespoons butter or margarine
2 tablespoons and 2 teaspoons all-purpose flour
1 cup and 3 tablespoons chicken broth
1 tablespoon and 1 teaspoon mayonnaise
1/2 teaspoon salt
1/8 teaspoon pepper
Paprika

Directions
In a greased 2-1/2-qt. baking dish, layer potatoes and onion.
In a saucepan, melt the butter; stir in flour until smooth. Gradually add broth, mayonnaise, salt and pepper; cook and stir for 2 minutes or until thick and bubbly. Pour over potatoes. Sprinkle with paprika.
Cover and bake at 325 degrees for 2 hours or until tender.
Modifications
I only used 3 potatoes, but one was fairly large
I forgot to add the mayonnaise
I didn't have paprika
I added 5 strips of bacon (pre-cooked Kirkland Signature kind from Costco)
I sliced enough medium cheddar cheese to cover the potatoes
I didn't grease the pan (it didn't need it)
I used aluminum foil to cover it and I had the shiny side facing outward
I cooked for approximately one hour and then I added the bacon and cheese
After adding the bacon and cheese, I let it cook approximately 30 more minutes without the foil cover
There you have it! Let me know if you have any questions or if you modify it yourself and it turns out delicious.
