3. Prepare the Potatoes

1. Peel and slice 2 pounds each of sweet potatoes and Yukon Gold potatoes into 1/8-inch thick rounds. For best results, use a mandoline for precision.

Common Mistakes to Avoid & How to Perfect the Recipe

1. Uneven Slices:
   • Problem: Uneven slices can lead to some pieces being undercooked while others overcook.
   • Solution: Use a mandoline or sharp knife for consistent slicing.
2. Skipping the Water Soak:
   • Problem: Potatoes may discolor or stick together during assembly.
   • Solution: Keep slices submerged in water while preparing.
3. Overbaking Without Cover:
   • Problem: Baking uncovered for too long can dry out the dish.
   • Solution: Cover the dish with foil for the first bake to lock in moisture and remove it only for browning.
4. Caramelizing Too Quickly:
   • Problem: Rushing the onions can result in a bitter taste.
   • Solution: Cook the onions slowly over low to medium-low heat for the best results.

FAQs

1. Can I make this dish vegan?

Absolutely! Replace the melted butter with olive oil or a vegan butter substitute to keep it plant-based. The caramelized onions and potatoes retain their rich flavor without dairy.

---

2. What other potato varieties can I use?

You can substitute Yukon Golds with Russet or red potatoes, but Yukon Golds are recommended for their creamy texture and buttery flavor. Similarly, white sweet potatoes or Japanese purple sweet potatoes can replace orange sweet potatoes for variety.

---

3. Can I make this recipe ahead of time?

Yes! Assemble the dish up to a day in advance, cover it tightly with foil, and refrigerate. When ready to serve, bake directly from the refrigerator, adding an extra 10-15 minutes to the baking time.

4. Can I add other vegetables?

Certainly! Thinly sliced parsnips, turnips, or carrots make excellent additions to the layers. Be sure to slice them to the same thickness as the potatoes for even cooking.

5. Why are my onions not caramelizing properly?

Caramelization requires patience and low to medium-low heat. If your onions are browning too quickly or sticking, reduce the heat and add a splash of water to the pan to prevent burning.
