Ingredients :
- 4–5 large potatoes, thinly sliced
- 1 medium onion, thinly sliced
- 2 cups shredded cheddar cheese
- 2 cups milk (or half-and-half for extra creaminess)
- 3 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 teaspoon garlic powder
- 1 teaspoon salt (adjust to taste)
- ½ teaspoon black pepper
Optional Add-Ins
- Parmesan cheese for extra flavor
- Fresh thyme or parsley
- Crispy bacon bits
- A pinch of paprika for color
Instructions :
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or non-stick spray.
Step 2: Prepare the Potatoes and Onions
Wash and peel the potatoes if desired, then slice them thinly and evenly. Slice the onions into thin rings or half-moons.
Uniform slicing helps the potatoes cook evenly and creates a soft, layered texture.
Step 3: Make the Cheese Sauce
In a saucepan over medium heat, melt the butter. Stir in the flour and cook for about 1 minute to form a light roux.
Slowly whisk in the milk, making sure there are no lumps. Continue stirring until the sauce begins to thicken.
Add garlic powder, salt, and black pepper. Once thickened, stir in most of the shredded cheddar cheese, reserving a small amount for topping.
Step 4: Layer the Dish
In the prepared baking dish, arrange a layer of sliced potatoes followed by a layer of onions. Pour some cheese sauce over the top.
Repeat the layers until all ingredients are used, finishing with sauce on top.
Step 5: Add Cheese Topping
Sprinkle the remaining cheddar cheese evenly over the top layer for a golden, cheesy crust.
Step 6: Bake
Cover the dish with foil and bake for 45 minutes. Then remove the foil and bake for another 20–25 minutes, or until the potatoes are tender and the top is golden and bubbly.
Step 7: Rest Before Serving
Let the dish sit for about 10 minutes before serving. This helps the sauce set and makes it easier to slice and serve.
Tips for Best Results
- Slice potatoes evenly for consistent cooking
- Use starchy potatoes like Russets for a creamier texture
- Don’t rush the sauce—thickening it properly is key
- Let the dish rest before serving to avoid runny sauce
