Crockpot Cheddar Green Chile Scalloped Potatoes Step-by-step instructions

Before you start

Before you begin, make sure your slow cooker is clean and dry. Thinly slice the potatoes using a mandoline or a sharp knife; aim for uniform 1/8-inch rounds so they cook evenly. If you're using a mandoline, use the guard to protect your fingers.

Have the green chiles, condensed soup, shredded cheese, and butter measured and ready. You can prep the potatoes and chiles up to a day ahead, storing them in the refrigerator in airtight containers. The soup and cheese can be measured and kept refrigerated as well. This makes assembly a breeze when you're ready to cook.

Instructions

Layer the potatoes and toppings

1. 1Layer the potato base
   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 overlapping layers along the bottom of the slow cooker. Scatter one-third of the chopped green chiles over the potatoes, then drizzle with one-third of the condensed cheddar cheese soup. Repeat the layers twice more, finishing with the last of the soup on top.
   Look for The potatoes should be evenly layered with chiles and soup between each layer.
   Tip Use a mandoline for uniform 1/8-inch slices so the potatoes cook evenly.
2. 2Top with cheese and butter
   Sprinkle the shredded sharp cheddar cheese evenly over the top of the potato mixture. Dot with the butter pats, spacing them evenly across the surface. Do not stir the ingredients together; leave the layers intact for the best texture.
   Look for The cheese and butter form a thick blanket over the potatoes.
   Tip If using unsalted butter, add a pinch of salt to the layer.

You should see neat layers of potato slices with green chiles and soup between them. The cheese and butter on top create a thick, appetizing blanket. The slow cooker should be about two-thirds full. This is the assembly phase, so there's no cooking yet, but the ingredients should look fresh and vibrant.

Slow cook until fork-tender

3. 3Slow cook until tender
   Cover the slow cooker with the lid. Cook on LOW for 7 to 8 hours or on HIGH for 3 to 4 hours, until the potatoes are fork-tender and the sauce is bubbling around the edges. Do not lift the lid during the first 4 hours of cooking on LOW (or 2 hours on HIGH) to maintain heat and moisture.
   Look for The sauce will be bubbly and the top will be golden brown.
   Tip If the top browns too quickly, you can cover it with foil or turn the slow cooker to WARM briefly.
4. 4Check for doneness
   After the minimum cooking time, insert a paring knife or fork into the center of the potatoes. They should slide in with little resistance. If the potatoes are still firm, continue cooking in 30-minute increments on LOW until tender. The cheese should be melted and the edges lightly browned.
   Look for A knife inserted into the center meets no resistance.
   Tip If the top is getting too dark but the potatoes are not done, cover with foil and continue cooking.

After several hours, the slow cooker will be filled with a bubbling, fragrant sauce. The cheese on top will be melted and starting to brown at the edges. The potatoes should be tender when pierced with a fork, and the sauce should be creamy and slightly thickened. The aroma of cheddar and green chiles will fill the kitchen.

Rest and serve

5. 5Rest before serving
   Turn off the slow cooker and let the potatoes rest, uncovered, for 5 to 10 minutes. This allows the sauce to thicken slightly and the layers to set, making serving easier. Spoon onto plates or a serving platter, making sure to include some of the golden crust from the top.
   Look for The sauce thickens slightly as it rests.
   Tip Use a wide spatula or slotted spoon to lift out portions without breaking the layers.

After turning off the slow cooker, the sauce will settle and thicken slightly. The top cheese crust will be set but still glossy. When you spoon out a portion, you'll see distinct layers of potato and sauce, and the potatoes will be perfectly tender. The dish should hold its shape on the plate.

Common mistakes

One common mistake is lifting the lid too often during cooking, which releases heat and extends cooking time. Resist the urge to peek for at least the first 4 hours on LOW.

Another mistake is using a slow cooker that is too small; the potatoes should fit comfortably without being packed too tightly, which can lead to uneven cooking.

Also, avoid using pre-shredded cheese for the topping, as it doesn't melt as smoothly. Finally, don't skip the rest time—it helps the layers firm up so you can serve neat portions.

How to tell it’s done

The potatoes are done when a fork or paring knife slides into the center of the potato layers with little to no resistance. The sauce should be bubbling around the edges and the top should be golden brown, with some spots of browned cheese.

If the potatoes are still firm, continue cooking on LOW in 30-minute increments. The total cooking time can vary depending on the thickness of your potato slices and your slow cooker model. Once done, let the dish rest for 5 minutes before serving to allow the sauce to set slightly.
