Ingredients:
- 4 medium potatoes
- 1 large onion
- Swiss cheese, sliced
- 2 cups half-and-half
- Butter
- Salt and pepper to taste
Instructions:
-
Preheat Oven: Start by preheating your oven to 425Β°F (220Β°C). This ensures that your gratin cooks evenly and develops a golden, crispy top.
-
-
Prepare Baker: Spray an oval baker with cooking spray to prevent the gratin from sticking to the dish during baking. This step makes cleanup a breeze!
-
Layer Ingredients: Begin assembling your gratin by creating layers of potatoes, onions, and Swiss cheese. Peel and thinly slice the potatoes and onion.
- Place a layer of sliced potatoes at the bottom of the baker.
- Top the potatoes with a layer of sliced onions.
- Arrange slices of Swiss cheese over the onions.
- Season each layer with salt and pepper to enhance the flavors.
Repeat these layers until you’ve used up all your ingredients, ensuring that the top layer consists of potatoes and cheese.
-
Add Half-and-Half: Once you’ve layered all the ingredients, pour the half-and-half over the gratin until it reaches the same height as the layers. This creamy addition adds richness and moisture to the dish as it bakes.
-
Dot with Butter: Dot the top of the gratin with small pieces of butter. As the gratin bakes, the butter melts and adds a luxurious richness to each bite.
-
Bake Covered: Cover the baker with a lid or aluminum foil to trap steam and moisture, allowing the ingredients to cook and meld together beautifully. Bake the gratin in the preheated oven for 45 minutes.
-
Uncover and Bake: After 45 minutes, remove the cover from the baker to allow the top of the gratin to brown and crisp up. Return the gratin to the oven and bake for an additional 15 minutes, or until the top is golden brown and bubbling.
-
Serve and Enjoy: Once the gratin is done baking, remove it from the oven and let it cool for a few minutes before serving. Scoop out generous portions of this comforting dish and savor each creamy, flavorful bite!
