Cost: $8.70 total, $2.17 per serving
Ingredients
- 3 large Large Potatoes (Russet or Idaho potatoes, scrubbed clean)
- 0.5 cup Onion (minced)
- 1 teaspoon Kosher Salt (large‑grain kosher salt)
- 0.5 teaspoon White Pepper (freshly ground)
- 0.25 teaspoon Cayenne Pepper (plus extra for dusting)
- 2 cups Sharp White Cheddar Cheese (grated)
- 1 cup Sour Cream (full‑fat)
Instructions
Preheat and Bake Potatoes
Preheat the oven to 400°F. Place the three whole potatoes directly on the oven rack and bake for 1 hour and 15 minutes, or until tender when pierced with a fork.
Time: PT1H15M
Temperature: 400°F
Cool Potatoes Completely
Remove the potatoes from the oven and let them cool on a rack until they reach room temperature (about 30 minutes). They must be completely cold before grating.
Time: PT30M
Grate Cold Potatoes
Using a box grater, grate the cooled potatoes into a large mixing bowl.
Time: PT10M
Season the Potatoes
Add the minced onion, kosher salt, white pepper, and cayenne pepper to the grated potatoes. Toss gently to distribute the seasoning evenly.
Time: PT5M
Incorporate Cheese
Fold in the grated sharp white cheddar cheese, mixing carefully so the cheese stays in small clumps and doesn’t melt prematurely.
Time: PT5M
Add Sour Cream
Gently fold in the sour cream until the mixture is just barely combined; you should still see distinct potato shreds.
Time: PT5M
Transfer to Baking Sheet
Spread the potato mixture evenly on the prepared baking sheet, smoothing the top with a spatula. Dust a light layer of cayenne pepper over the surface for color and heat.
Time: PT5M
Final Bake
Increase the oven temperature to 425°F and bake the gratin for about 30 minutes, or until the center is piping hot and the top is golden‑brown.
Time: PT30M
Temperature: 425°F
Serve
Remove from the oven, let rest 5 minutes, then serve hot as a side to steak, chicken, or any main dish.
Time: PT5M

Chef Tips from the Video
- Use a sharp white cheddar for the best tangy flavor.
- Grating the potatoes while they are fully chilled prevents them from turning mushy.
- A pinch of smoked paprika can replace cayenne for a smoky twist.
Troubleshooting

Broil for 2–3 minutes, watching closely to avoid burning.
Gratin is watery.
Make sure potatoes are completely cold before grating and avoid over‑mixing the sour cream.
Cheese clumps together.
Fold cheese in gently and keep the mixture cool; add cheese just before the final bake.

Make-Ahead Tips

Why does this Food Wishes recipe use a two‑stage baking method (400°F then 425°F) instead of a single temperature?
The lower temperature first cooks the potatoes through without drying them out. The higher temperature at the end creates a golden, crispy top while ensuring the interior is piping hot.
