Potato and Onion Gratin
This Potato and Onion Gratin combines thinly sliced potatoes and onions with sharp cheddar cheese, fresh herbs such as marjoram, and rich cream to create a tender, cheesy bake. Butter dots enhance the richness and help achieve a golden crust. The gratin is baked covered to cook through, then uncovered to brown the top, resulting in tender, flavorful layers with a creamy texture.

Ingredients
- 2 baking potato washed and peeled, Russet variety
- 1 onion medium
- 1 tsp salt fresh cracked, to taste
- 1 tsp black pepper fresh cracked, to taste
- 2 cups cheddar cheese divided, sharp, shredded
- 1 cup heavy cream divided
- 3 Tbsp marjoram oregano, or thyme leaves, plus for for garnish, fresh
- 2 Tbsp butter cut in pieces
Instructions
- Set oven to 350F
- Slice the peeled potatoes into 1/8 inch slices with a mandoline slicer.
- Slice the onions the same way. Cut the onion slices into quarters so there will be no long stringy pieces.
- In a very large bowl add the onions, potato slices, 3/4 cup of the cream, the fresh herbs, and 1 1/2 cups of the cheese ~ mix well with clean hands. Season with salt and cracked pepper. Separate the potato slices as best you can.
- Pile the mixture into an 11-12 inch gratin dish. Arrange the potatoes evenly. Dot with the butter.
- Blend the remaining cheese and cream together
- Dot the potatoes with the pieces of butter, and then top with the remaining cheese and cream.
- Cover loosely with foil and bake for about 90 minutes, or until browned and bubbling, and you can easily pierce the potatoes with the tip of a sharp knife. Remove the foil for the last 1/2 hour of baking.
- Run under the broiler at the end if you want more browning.
