Ingredients
For the base:
- 6-7 medium yukon gold potatoes thinly spiced
- 1/2 white onion cut into slices
- 1/2 cup gruyere cheese for topping
- 1/4 cup grated parmesan for topping
- 1-2 tbsp fresh parsley for garnish
For the sauce:
- 2 tbsp butter
- 1/4 cup flour
- 1.5 cups milk
- 8 oz sharp cheddar cheese about 2 cups
- 1/2 tsp garlic powder
- 3/4 tsp salt
- freshly ground black pepper to taste
Instructions
- Preheat the oven to 375 degrees & grease a square baking dish with a little butter.
- Place sliced potatoes in three tight slanted rows and add in onion slices between the rows wherever you can fit them.
- Next make your sauce: add butter to a pan on medium heat until butter is melted. Then whisk in the flour and slowly add in milk, whisking constantly to prevent lumps until it’s a similar consistency to creamy gravy.
- Turn heat to low and stir in shredded cheddar cheese, garlic powder, salt and pepper. Stir together until smooth.
- Pour cheese sauce over potatoes, cover with foil & bake for 45 minutes.
- Remove foil, add gruyere & parmesan and bake again uncovered for another 30-45 minutes until potatoes are done and your cheese is golden brown on top.
- Garnish with fresh chopped parsley and enjoy!
