Frequently Asked Questions
- → Can this be prepared early?
- Yes, you can build it up to a day ahead and refrigerate. Just bake a bit longer if starting cold.
- → Why is ¼ inch potato slices important?
- It helps them cook evenly while keeping their shape. Thinner slices might break; thicker ones won't cook enough.
- → Is it okay to use other cheeses?
- Totally! Go with Colby Jack, a mix of cheesy favorites, or whatever melts well for you.
- → Why foil the dish while baking?
- The foil stops the top from overbrowning while the potatoes finish cooking underneath. Take it off near the end to brown.
- → How can I tell when it's ready?
- The potatoes should be fork-tender, the sauce bubbly, and the top golden and delicious.
