This breakfast casserole is an homage to one Julia Child dreamed up, and known as Râpée Morvandelle. Which means a gratin of grated cheese and potatoes. And other things. There are a million recipes for this, but here’s mine with all the changes I made.
If you are cooking this for our ward Christmas Party, please make it that morning, and bring it — covered in foil — HOT to the church by about 9:30 a.m.
We will provide the cubed ham, the butter, and a chunk of cheese. The other ingredients you will need to provide. Below are some photos from food prep. The recipe begins below them.

Ingredients
1 small yellow onion, small dice (about 1/2 to 2/3 cup)
2 cloves garlic, grated or minced–but not crushed
2 Tbs. extra virgin olive oil
6 Tbs. butter, divided into three parts of 2 Tbs each
4 eggs
1/2 cup heavy cream
8 ounces grated mild Cheddar cheese, divided
1/2 teaspoon ground pepper
2 tsp Kosher salt [NOTE: if you are using table salt, cut back slightly on the amount, say 1 3/4 teaspoons.]
1 30-ounce bag frozen shredded hash brown potatoes
8 ounces cubed good-quality ham
Directions
- Preheat your oven to 375 degrees while you get everything else prepped up.
- Sauté the onion in 2 Tbsp. olive oil and 2 Tbsp butter, over medium heat for about 5 minutes, until tender but not browned. Remove from heat and add the grated/minced garlic. Stir it and allow it to sit in the warm pan with the onion. Set aside.
- Whisk together the egg, cream, salt, and pepper.
- Place your baking dish in the oven with 2 Tbsp of butter and let the butter melt and the pan get hot while you combine everything. Keep an eye on the butter so it doesn’t burn.
- In a large bowl add the potato shreds and 6 ounces of the grated cheddar cheese and toss.
- Add in the onion and garlic mixture and toss it again.
- Pour the cream and egg mixture over the potato mixture, and toss well to coat every potato shred.
- Place the potato mixture into your hot baking dish and top with the cubes of ham.
- Cut 2 Tbs. butter into small bits, then dot the casserole with butter.
- Over the top of everything, add the remaining grated cheese (a couple of handfuls, or roughly 2 ounces).
- Bake for 35 minutes or until lightly browned in places.
Cover with foil and BRING TO CHURCH AT 9:30 A.M. while it’s HOT!
NOTE: It is not recommended to make this ahead, as the cook time will need to be adjusted (maybe even doubled) for a cold pan. However all ingredients can be prepped in advance. The casserole takes only about 10-15 minutes to throw together if ingredients are prepped. Putting it in the hot pan with melted butter will yield a more satisfying crust on the bottom.
