Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat oven to 375°F (190°C). Grease a 9×13 baking dish or similar-sized casserole dish with butter.
Step 2: Make the Cheese Sauce
In a saucepan, melt butter over medium heat. Add garlic and cook for 30 seconds. Stir in flour and cook for 1 minute to form a roux. Slowly whisk in cream and milk. Add salt, pepper, and nutmeg. Simmer until slightly thickened (4-5 minutes). Stir in 1 cup cheddar and 1/2 cup Monterey Jack until smooth.
Step 3: Layer the Potatoes
Layer half the sliced potatoes in the baking dish. Pour half the cheese sauce over the top. Repeat with remaining potatoes and sauce.
Step 4: Bake Until Golden
Cover with foil and bake for 40 minutes. Remove foil, top with remaining 1/2 cup cheddar cheese, and bake another 20 minutes until bubbly and golden on top.
Step 5: Cool and Serve
Let the dish rest for 10 minutes before serving. Garnish with chopped parsley if desired.
