O’Brien Potato Bake Slow Cooker. A creamy, cheesy potato dish with colorful peppers and onions that cooks itself while you relax! This easy slow cooker potato bake uses just four simple ingredients to make something truly special. Frozen O’Brien potatoes mix with creamy soup, tangy sour cream, and melty cheddar cheese to create a warm, bubbly dish your whole family will love any time of day.
This 4-ingredient slow cooker O’Brien potato bake is the kind of old-fashioned comfort food that many of us who grew up in the Midwest know and love. It uses a bag of frozen O’Brien potatoes — those little diced potatoes with colorful peppers and onions that were super popular in American diners and home kitchens back in the mid-1900s. You just mix them with three easy pantry ingredients, and the slow cooker does all the hard work while you go about your day. The result is a rich, creamy, and savory potato dish that slowly bubbles away all afternoon long.
You can serve this potato bake right out of the slow cooker, scooped into shallow bowls or spooned onto plates. It goes really well with roasted sausages, meatloaf, baked chicken, or a simple green salad on the side. If you want to serve it at brunch, it tastes amazing next to scrambled eggs, crispy bacon, or ham with some fresh fruit. Adding something crunchy on the side — like buttered toast, crusty bread, or a green salad with a zippy dressing — helps balance out all that creamy, cheesy goodness.

O’Brien Potato Bake Slow Cooker
O’Brien Potato Bake: Directions
- Grease your slow cooker. Spray the inside of a 4- to 6-quart slow cooker with nonstick cooking spray, or rub a little neutral oil all around the inside. This keeps the potatoes from sticking to the sides.
- Make the creamy sauce. In a medium bowl, whisk together the condensed cream of mushroom soup and sour cream until the mixture is smooth and well blended. Then stir in the shredded cheddar cheese until it is spread throughout. Add the salt and black pepper if you are using them.
- Add the potatoes. Open the bag of frozen O’Brien potatoes and pour them straight into the greased slow cooker. Spread them out into an even layer. You should be able to see the peppers and onions scattered all throughout.
- Pour on the sauce. Spoon the creamy soup, sour cream, and cheese mixture right on top of the frozen potatoes. Use a spatula or big spoon to gently fold and stir everything together so most of the potatoes get coated. Don’t stress if a few spots look plain — those potatoes will soak up all the good flavor while they cook.
- Cook low and slow. Put the lid on the slow cooker. Cook on LOW for 4 to 5 hours, or on HIGH for 2 to 3 hours, until the potatoes are soft and tender and the edges look hot and bubbly. Try not to lift the lid too many times while it cooks — every time you peek, heat escapes and it takes longer to finish.
- Give it a stir. Once the potatoes are nice and tender, stir everything gently so the sauce and melted cheese gets mixed back in evenly. Taste a little bit of it. If you think it needs more flavor, add a bit more salt or pepper.
- Serve and enjoy!
