Frequently Asked Questions
Can I use different potatoes?
Yes. Yukon Golds are ideal for their creamy, buttery texture, but Russets, red potatoes, or even fingerlings work well. Russets are starchier and will thicken the dish more, while red potatoes hold their shape and provide a firmer bite. The key is to slice them evenly. You can even mix potato varieties for a range of textures and colors.
What if I don’t have a slow cooker?
You can bake this dish in the oven. Layer the potatoes and onions in a greased 9×13-inch baking dish, add the seasonings, melted butter, and broth, cover tightly with foil, and bake at 375°F for about 50–60 minutes, until the potatoes are tender. Remove the foil, add cheese if using, and bake uncovered for another 10–15 minutes until golden. You can also broil at the end for a crisp top.
How do I prevent the potatoes from turning brown while I slice?
If you’re slicing the potatoes in advance, place the sliced rounds in a bowl of cold water as you work. This prevents oxidation and keeps them white. When you’re ready to assemble, drain them very well and pat them completely dry with a clean kitchen towel. Excess water can dilute the dish.
Can I make this dish dairy-free?
You can use a plant-based butter and omit the cheese, or use a dairy-free shredded cheese alternative. The butter is important for richness, so choose a good-quality vegan butter that melts well. The broth should also be dairy-free; vegetable broth is naturally dairy-free. The result will be lighter but still very flavorful.
Why are my potatoes still firm after the cooking time?
The slices may be too thick, or the slow cooker may not be reaching a high enough temperature. Check that the lid is sealed properly and that the cooker is on the correct setting. If the potatoes are still firm, simply continue cooking on HIGH for an additional 30–60 minutes, checking every 15 minutes, until a fork inserts easily. Slicing them more thinly next time will help.

Ingredients

Notes
- For a main-course version, add smoked sausage, bacon, ham, or cooked ground beef between the layers.
- For a creamier texture, stir in ½ cup sour cream or a can of cream of mushroom soup before the final cook time.
- Leftovers keep in the fridge for up to 4 days. Reheat in the microwave, oven, or stovetop with a splash of broth or butter.
