Take your piece of aluminum foil and press it into your 4 quart slow cooker insert to make a boat.
Spray your foil boat with cooking spray
Layer one potato's worth of thin slices in the bottom of your foil boat and sprinkle with salt and pepper.
Spread out half of your onion slices on top of your potatoes.
Lay 2 of your bacon slices on top of everything.
Repeat layers and close up your foil boat.
Cover and cook on low for 4-6 hours or 2-3 hours on high. (It is done when your potatoes are fork tender.)

As with any of our recipes, carb counts, calorie counts and nutritional information varies greatly. As a result, your nutritional content depends on which products you choose to use when cooking this dish. The auto-calculation is just an automated estimate and should NOT be used for specific dietary needs.
All slow cookers cook differently, so cooking times are always a basic guideline. Recipes should always be tested first in your own slow cooker and time adjusted as needed.
