Homemade Gratin Potato's with Steak

This potato recipe is wonderful! But, it makes enough for about 10 people so I used less potato's and put it in an 8x8 instead of a 9x13. I did however, make the full amount of cheese sauce because it is sooo good!

Take a few potato's, peel and slice them up thinly
For the cheese sauce you will need Dijon mustard, butter (the whole cube), Cheddar cheese, Swiss cheese and also a little milk.

To make the sauce, melt 1/2 cup butter over medium heat. Stir in 1/2 cup of flour with a whisk until smooth. Gradually add 2-3 cups of milk. Heat to a boil, reduce heat to low stirring frequently until sauce thickens. Then, add 1 tblsp Dijon mustard, 1 1/2 cups shredded Cheddar cheese and 1 1/2 cups shredded Swiss cheese. Stir until cheese is all melted.

You'll want to boil the potato slices in water for 5-10 minutes to soften them up a bit before layering them in the pan. Layer half the potato's in a greased pan, season with a little salt and pepper.

Pour half the sauce then add the rest of the potato's and cover with the remaining sauce.

Bake for an hour at 350.

The rib eye steaks have been marinating for 8+ hours in the following marinade;

1/4 cup oil, 1/4 cup lemon juice, 2 tblsp soy sauce, 1/2 tsp salt, 1/4 tsp pepper, 3 cloves minced garlic, 1 tblsp sugar.

Grilled and ready to eat!
