- 4 medium russet or Yukon Gold potatoes, peeled and thinly sliced
- 2 cans sliced carrots, drained well
- 1 can condensed cream of mushroom soup
- 2 cups shredded cheddar cheese
How to Make Slow Cooker 4-Ingredient Potato and Canned Carrots Casserole
1. Prepare the Slow Cooker
Lightly grease the inside of a 5- to 6-quart slow cooker with cooking spray or butter.
2. Add the First Potato Layer
Place half of the sliced potatoes in an even layer across the bottom of the slow cooker.
3. Add the Carrots
Spread half of the drained canned carrots over the potatoes.
4. Add the Soup and Cheese
Spoon half of the cream of mushroom soup over the carrots and potatoes. Spread it as evenly as possible.
Sprinkle half of the shredded cheddar cheese over the soup.
5. Repeat the Layers
Add the remaining potatoes, followed by the remaining carrots. Spread the rest of the condensed soup over the top and finish with the remaining cheddar cheese.
6. Cook
Cover and cook on LOW for 5 to 6 hours, or until the potatoes are completely tender when pierced with a fork.
Cooking times can vary depending on the slow cooker and how thinly the potatoes are sliced, so begin checking toward the end of the cooking time.
7. Rest and Serve
Turn off the slow cooker and let the casserole rest for about 5 minutes before serving. This allows the creamy sauce to settle and makes the casserole easier to spoon onto plates.
Tips for the Best Slow Cooker Potato Casserole
Slice the potatoes evenly. Consistent slices help the potatoes cook at the same rate.
Drain the canned carrots thoroughly. Too much liquid can make the casserole watery.
For the best results, avoid lifting the slow cooker lid unnecessarily. Keeping the heat inside helps the potatoes cook properly.
Yukon Gold potatoes are especially good for this recipe because they have a naturally creamy texture. Russet potatoes also work well and tend to absorb the sauce beautifully.
For a stronger cheese flavor, use sharp cheddar. Mild cheddar can be used if you prefer a more subtle flavor.
Easy Variations
Although this recipe is delicious as written, there are several simple ways to change it.
Add cooked crumbled bacon between the layers for a smoky, savory casserole.
Replace some of the cheddar with Monterey Jack or Colby cheese for a different flavor.
Add a little black pepper or garlic powder if you want additional seasoning.
For a heartier dish, add diced cooked ham between the potato and carrot layers.
Cream of chicken soup can also be substituted for cream of mushroom soup.
What to Serve With It
This casserole makes an excellent side dish for roasted chicken, pork chops, meatloaf, roast beef, baked ham, or grilled sausages.
It is also a great addition to a holiday meal. Serve it alongside turkey or ham with green beans, stuffing, rolls, and cranberry sauce for a comforting family-style dinner.
Make-Ahead Option
You can prepare the ingredients and layer the casserole several hours before cooking. Cover the prepared slow cooker and refrigerate it until you are ready to cook.
If the ingredients are very cold when cooking begins, the casserole may require a little additional cooking time.
How to Store Leftovers
Allow leftover casserole to cool before transferring it to an airtight container.
Refrigerate for up to 3 to 4 days. Reheat individual portions in the microwave or reheat larger portions gently in the oven until hot.
Frequently Asked Questions
Can I use fresh carrots instead of canned carrots?
Yes. Fresh carrots can be used, but they will have a firmer texture and may require additional cooking time. Canned carrots are convenient because they are already tender.
Can I use baby potatoes?
Yes. Baby potatoes can be used as long as they are sliced thinly enough to become tender during the cooking time.
Can I use another type of cheese?
Absolutely. Cheddar is an excellent choice, but Colby, Monterey Jack, or a combination of cheeses can also be used.
Can I cook the casserole on HIGH?
Yes, although LOW is recommended for the most even cooking. If cooking on HIGH, start checking the potatoes after approximately 3 hours.
Can I add meat?
Yes. Cooked diced ham or cooked crumbled bacon are particularly good additions. Make sure any meat added is already fully cooked before it goes into the slow cooker.
