Phil's Au Gratin Potatoes

• 3 Tbsp butter
• 3 Tbsp flour
• 1/2 Tbsp parsley, finely chopped
• 1/2 Tbsp garlic, minced
• 1 1/2 cups milk
• salt
• pepper
• 8-10 medium yellow/red potatoes, sliced
• 1 cup peas
• 2 1/2 cups cheddar cheese, grated
• 1/2 cup Swiss cheese, grated
• 1/2 tsp chilli pepper

Preheat oven to 350°F.

In a 3qt pan, melt butter on medium-low heat. When butter is melted, add flour and whisk for 2 min or until flour is lightly browned. Next, add the garlic and parsley to the roux and stir just to combine. Add the milk and bring to a simmer whisking continuously. The sauce should thicken. Remove sauce from the heat and then mix in 1 1/2 cups cheddar and 1/2 cup Swiss cheeses adding slowly to avoid clumps. Salt and pepper to taste. Add peas to the sauce.

In a 8x8" glass casserole dish, pour just enough sauce to coat the bottom of the dish. 

Slice potatoes thinly, about 1/8" thick, and layer them in the dish. Alternate one layer of sauce to coat and then a layer of sliced potatoes. There should be about 5 layers of potatoes.

Pour remaining sauce on the top and then cover with the remaining 1 cup of cheddar cheese.

Bake at 350°F for 80-90 minutes or until the the potatoes are fork tender and the cheese on top is browned.
