There can never be enough potato dishes in our Irish household, so I am forever looking for new & different ways to make them. Bacon adds lots of flavor to many savory dishes, & since I had purchased the Bacon ends & pieces on sale at a fraction of what a good quality pound of bacon would cost, I thought it was befitting to use it with the potatoes. I have quite a few Potato casserole dishes posted & this just adds to them, it is so cheesy & tasty & the bacon & onions really flavors them very well. Hope you will give it a try. I can't begin to tell you how much my hubby loved these potatoes.

1 Hr 5 Min


  • 3 lb
    potatoes, yukon gold, red or russet
  • 1 lb
    bacon, i used ends and pieces
  • 1/2 stick
  • 4 Tbsp
    flour, all purpose
  • 3 c
  • 2 c
    sharp cheddar cheese
  • 1 c
    mozzarella cheese
  • 2 tsp
    granulated garlic
  • 1 1/2 tsp
    black pepper
  • 2-3 tsp
    kosher salt (added to pot of potatoes)
  • 2 medium
    onions, chopped



  1. Preheat oven to 350 degrees F. Spray a 9 X13 size casserole dish with cooking spray and set aside.
  2. I prefer to peel my potatoes then place them in a pot of water and boil them whole or cut in half until they are just about done, this usually takes about 15 to 20 minutes depending on how many potatoes you have. This hastens the baking time. Don't forget to add salt to the water to add flavor to the potatoes. The salt infuses the potatoes during the boiling time. Slice potatoes when cool enough to handle.
  3. Cook the bacon in a large skillet, over medium high heat, remove bacon to a platter lined with paper towel as it cooks up crisp, repeat until all is cooked, but reserve the drippings.
  4. Add the onions to skillet of reserved bacon drippings, then cook until onions begin to become transparent, add in bacon pieces and continue to cook to blend the flavors together.
  5. Remove bacon and onions from skillet to a plate or small bowl, then add in the half stick of butter, and allow to melt, then add in the flour, and whisk until flour blends with the butter, creating a paste.
  6. Add in the milk and stir until flour mixture begins to blend into the milk, add in granulated garlic and pepper, stir and continue cooking over low heat until mixture begins to thicken and coat the back of a spoon. Then add in both shredded cheeses and stir until cheese is melted & mixture is creamy and smooth. Remove from heat.
  7. Now add a layer of the potatoes to bottom of casserole dish, then top with the bacon and onion mixture,and about half of the cheese mixture. I also added extra shredded cheese between each layer and on top.
  8. Repeat with potatoes & remaining cheese sauce. Bake in preheated 350 degree F. oven for 35 minutes or until hot and bubbly. Allow to cool and serve with your favorite entree.
  9. This is the finished dish.
