Directions and Instructions
- Begin by lightly greasing the inside of a 4- to 6-quart slow cooker with a small amount of butter. This will help prevent sticking and create those beautifully golden edges on your bake.
- Next, peel the potatoes and slice them into thin rounds, about 1/8 inch thick. If you have a mandoline, it can help achieve even thickness! Place the slices in a large bowl and cover them loosely with a clean kitchen towel to keep them from drying out while you prepare the onions.
- Now, peel the onions and slice them into thin half-moons, making sure they’re similar in thickness to the potato slices. This will ensure everything cooks together beautifully.
- In a small bowl, mix the flour, salt, and pepper (if you’re using it) until well combined.
- Start layering in your slow cooker! Begin with an even layer of potato slices on the bottom, overlapping slightly as if laying shingles. Next, sprinkle a layer of sliced onions over the potatoes, followed by a light dusting of the flour mixture.
- Dot a few small pieces of butter—about 1 tablespoon total—over the flour and onions to infuse richness.
- Continue building your layers: potatoes, onions, a sprinkle of flour, and butter, until you’ve used all your ingredients. Aim to finish with a layer of potatoes on top, then add any remaining butter pieces over the surface.
- Cover the slow cooker with its lid and set it to cook on HIGH for 3 1/2 to 4 hours or on LOW for 6 to 7 hours. You’re looking for the potatoes to be very tender when pierced with a fork and the onions to be soft and caramelized.
- When the potatoes are ready, remove the lid and, if possible, let it sit on WARM or LOW for another 15 to 20 minutes with the lid slightly ajar. This extra time allows the flavors to meld beautifully.
- Finally, serve the potato and onion bake directly from the slow cooker. Be sure to scoop down through the layers, ensuring everyone gets a share of the buttery, caramelized onions along with the tender, browned potatoes.
Notes or Tips
- This dish is incredibly versatile—feel free to add herbs such as thyme or rosemary for a fragrant twist.
- If you’re short on time, prep everything the night before, layer it in the slow cooker, and pop it in the fridge. In the morning, simply set it to cook before you start your day!
- For a cheesy variation, add grated cheese in between the layers or sprinkle on top before the final few minutes of cooking.
Cooking Techniques
This recipe utilizes the slow cooking technique, allowing the flavors to merge beautifully over time. The gentle heat softens the potatoes while slowly caramelizing the onions, creating a dish that’s both comforting and full of depth. If you don’t have a slow cooker, you can achieve similar results in a covered baking dish in your oven at 325°F, just keep an eye on it to ensure it doesn’t dry out.
