Preparation Phase & Tools to Use
Before you dive into cooking, take a moment to prepare your kitchen. Make sure you have a reliable mandoline or sharp knife handy for slicing the potatoes thinly—this is key for perfect cooking and texture. A large baking dish is essential; you’d want one that can hold all those delicious layers without spilling over. Preheating the oven to 400°F (200°C) ahead of time ensures that your dish will bake evenly. Use an oven mitt to protect your hands when removing and placing the baking dish in the oven, and don’t forget a whisk for mixing your cream and milk with spices.

Ingredients
- 3 lbs russet potatoes, peeled and thinly sliced
- 2 cups heavy cream
- 1 cup whole milk
- 2 cups shredded cheddar cheese
- 1 cup shredded Monterey Jack cheese
- 1/2 cup grated Parmesan
- 3 tbsp butter
- 3 cloves garlic, minced
- 1 tsp salt
- 1/2 tsp black pepper
- 1/4 tsp nutmeg (optional)
- Fresh parsley for garnish
Instructions
Step 1: Preheat Your Oven
Begin your culinary adventure by preheating the oven to 400°F (200°C). This ensures that your potatoes au gratin will cook evenly and properly, creating that perfect golden crust we all crave.
Step 2: Prepare Your Baking Dish
Generously grease a baking dish with butter. This step is essential to prevent the potatoes from sticking and also adds extra flavor. A medium to large casserole dish is ideal to accommodate the layers of potatoes and sauce.
Step 3: Cook the Garlic and Cream Mixture
In a saucepan over medium heat, melt the butter, allowing it to start bubbling gently. Once melted, add in the minced garlic and sauté until aromatic—this should take about a minute. Next, pour in the heavy cream and milk, whisking to integrate the garlic thoroughly. As it warms, mix in the salt, pepper, and nutmeg; heat until the mixture is steaming but not boiling to ensure a smooth sauce.
Step 4: Layer the Potatoes
Start layering the sliced potatoes evenly in the prepared baking dish. The first layer should consist of half of the potato slices laid out methodically. Drizzle half of the warm cream mixture over this potato base. Follow by sprinkling half of your cheddar, Monterey Jack, and Parmesan cheeses over the top. This layering method creates a robust flavor profile, with every forkful delivering creamy osmosis of goodness.
Step 5: Complete the Layers
Now, repeat the process: lay down the remaining potato slices, top with the rest of the cream mixture, and finish with the remaining cheeses. This double layering creates a perfect texture balance between the soft potatoes and melted cheese.
Step 6: Bake to Perfection
Cover the baking dish tightly with aluminum foil to trap steam, ensuring the potatoes cook thoroughly. Bake in the preheated oven for 30 minutes, then remove the foil to let the top brown beautifully. Continue baking for an additional 20 minutes or until the top is bubbling and beautifully golden. This process not only cooks the gratin through, but it also gives you that irresistible crunchy cheese layer.
Step 7: Let It Rest
After pulling the dish from the oven, allow it to rest for around 10 minutes. This is a crucial step as it helps to consolidate the layers, making it easier to serve without them falling apart. Garnish with freshly chopped parsley just before serving for a pop of color!

Variations
- Protein: Add cooked, crumbled bacon or diced ham for a delightful protein boost.
- Vegetables: Layer thinly sliced onions or sautéed mushrooms for added depth of flavor.
- Spices: Experiment by adding smoked paprika or cayenne pepper for a hint of heat.
Cooking Notes
- Ensure your potato slices are uniform in thickness to guarantee even cooking.
- For a gluten-free version, double-check the cheese labels; most are gluten-free, but it’s worth confirming.
Serving Suggestions
- Pair this gratin with a perfectly cooked steak or roasted chicken for a gourmet dinner experience.
- Serve alongside a green salad dressed with lemon vinaigrette to balance the richness of the dish.
Tips
- Feel free to prepare the dish a day in advance until the baking stage, so all that’s left is to pop it in the oven.
- For a crispier cheese topping, broil for an additional 2-3 minutes after baking.
