Cheddar Sour Cream Scalloped Potatoes: Crockpot Dump Dinner Step-by-step instructions

Before you start

Before starting, lightly grease the slow cooker insert to prevent sticking. Slice the potatoes using a mandoline or sharp knife; keep the slices in a bowl of cold water if you're not layering them immediately to prevent browning.

Measure out the soup, sour cream, shredded cheese, and butter. Have all ingredients ready to assemble quickly. No need to pre-cook anything—this recipe is all about simplicity.

Instructions

Layer and Dump

1. 1Layer the Potatoes
   Lightly grease the inside of a 6-quart slow cooker with butter or nonstick spray. Arrange one-third of the sliced Yukon Gold potatoes in an even layer on the bottom, overlapping slightly like shingles. Repeat with the remaining potatoes to create three layers.
   Look for The potato slices should cover the bottom completely, with no gaps.
   Tip A mandoline makes quick work of slicing the potatoes uniformly thin, ensuring even cooking.

After layering the potatoes, soup mixture, cheese, and butter, the slow cooker should be filled to about three-quarters full. The top will look like a patchwork of cheese, butter, and creamy sauce—not perfectly smooth, but that's fine. The aroma is fresh and savory, with the sharp scent of cheddar. Before covering, ensure the top is as level as possible for even melting.

Slow Cook to Tender

2. 2Add the Creamy Mixture
   In a medium bowl, stir together the condensed cream of chicken soup and sour cream until smooth. Dollop this mixture over the potatoes, spreading it gently to cover most of the surface. It doesn't need to be perfect—the slow cooker will meld everything together.
   Look for The soup-sour cream mixture should be evenly distributed over the potatoes.
   Tip For easier spreading, let the sour cream come to room temperature before mixing.

After 3-4 hours on low, the kitchen will fill with the comforting aroma of melting cheese and simmering potatoes. The sauce will be bubbling gently around the edges, and the top will look golden and slightly puffed.

The potatoes should be nearly tender when pierced with a fork. If the top is browning too quickly, you can rotate the insert or lower the heat setting, though this is rarely necessary.

Serve and Enjoy

3. 3Top with Cheese and Butter
   Sprinkle the shredded sharp cheddar cheese evenly over the soup mixture. Dot the top with the pats of salted butter, spacing them out so they melt and create a golden crust.
   Look for The cheese should cover the top generously, with butter pats visible.
   Tip Use freshly shredded cheddar for the best melt; pre-shredded varieties may contain anti-caking agents that affect texture.

The final casserole will be bubbling, with a golden, crusty top and creamy sauce peeking through. The potatoes will be fork-tender, and the sauce will have thickened to a velvety consistency. The aroma is intensely cheesy and buttery. Let it rest for 5-10 minutes before serving to allow the sauce to set slightly, then scoop out generous portions with a large spoon.

Common mistakes

One common mistake is using pre-shredded cheese, which can lead to a gritty texture due to anti-caking agents. Another is overfilling the slow cooker—leave at least an inch of headspace so the sauce can bubble without overflowing.

Also, resist the urge to lift the lid and stir frequently; each time the lid is removed, heat escapes and extends cooking time. Finally, don't use waxy potatoes like red or new potatoes, as they won't soften properly and will remain crunchy.

How to tell it’s done

The potatoes are done when they are fork-tender: a knife or fork should slide through the thickest potato slice with no resistance. The sauce will be bubbly and thickened, and the top will have a golden, melted cheddar crust.

If the potatoes are still firm after the recommended time, continue cooking in 30-minute increments. The internal temperature of the casserole should reach at least 165°F (74°C) for food safety, though the potatoes will be soft well before that.
