It’s a family favorite that’s ideal for holidays, potlucks, and cozy dinners. With only three ingredients, it’s as simple as it is delicious.
📝 Ingredients
- 2 lbs (900 g) russet or Yukon Gold potatoes, peeled and thinly sliced
- 2 cups (480 ml) heavy cream (or half-and-half for a lighter version)
- 2 cups (200 g) shredded cheddar cheese
Optional (for garnish only)
- Chopped fresh parsley
- Cracked black pepper
Directions
- Preheat the oven (5 minutes).
Preheat to 375°F (190°C) and lightly grease a 9×13-inch baking dish. - Layer the potatoes (5 minutes).
Arrange half of the sliced potatoes evenly in the baking dish. - Add cream and cheese (3 minutes).
Pour half of the heavy cream over the potatoes and sprinkle with half of the shredded cheddar cheese. - Repeat the layers (3 minutes).
Add the remaining potatoes, cream, and cheese. - Bake covered (50 minutes).
Cover the dish tightly with foil and bake for 50 minutes. - Bake uncovered (20 minutes).
Remove the foil and continue baking for 20 minutes, until the top is golden brown and bubbling. - Rest before serving (10 minutes).
Let the casserole rest for 10 minutes to allow the creamy sauce to thicken before serving.
Heat Level
- 375°F (190°C) throughout baking.
Timing Tips
- Slice potatoes about ⅛-inch thick for even cooking.
- Check tenderness by inserting a fork into the center; it should slide in easily.
Texture & Visual Cues
- Potatoes should be fork-tender.
- Cheese should be golden and bubbly.
- Cream should thicken into a rich sauce.
- The edges should be lightly browned.
Cooking Tips
- Yukon Gold potatoes create an extra creamy texture.
- Freshly shredded cheese melts more smoothly than pre-shredded cheese.
- For extra flavor, add garlic powder, onion powder, or fresh thyme (optional).
- Avoid overbaking, which can cause the sauce to separate.
