My nana used to make this every week to make a little go a long way. With just four ingredients, it turns into a hearty meal that feels like pure comfort.

Tip: Consistency is key here. If some slices are thick and others are paper-thin, you’ll end up with a mix of mushy and crunchy potatoes. If you have a mandoline slicer, now is the time to use it!

Step 3: The Sauce Secret: In a bowl, whisk the two cans of soup with 1/2 cup of water. This thinness is intentional—it allows the sauce to trickle down through the potato layers rather than just sitting on top.

Step 4: The Layering Process:

• Bottom: 1/3 of the potatoes.
• Middle: 1/2 the beef, 1/3 the soup mixture, 1/2 cup cheese.
• Repeat: Another 1/3 potatoes, the rest of the beef, 1/3 soup, 1/2 cup cheese.
• Top: The last 1/3 of the potatoes, covered with the final 1/3 of the soup.

Step 5: Low and Slow: Cover and cook on LOW for 6/7 hours or HIGH for 3/4 hours. You want the potatoes to be “butter soft” when pierced with a fork.

Step 6: The Cheesy Finish 20/30 minutes before serving, sprinkle the remaining 1 cup of cheese over the top. Cover until melted and bubbly. Let it sit for 10 minutes with the lid off before scooping to let the sauce thicken.
