Rich Potato Gratin Ingredients
For the Gratin
• Starchy Potatoes (Russets or Yukon Golds) – Choose Russets for creaminess or Yukon Golds for a buttery flavor.
• Butter – Use unsalted butter to control seasoning while enriching the sauce.
• Onion (minced) – Adds depth; substitute with shallots for a gentler taste.
• Garlic (grated) – Fresh garlic enhances the flavor of the sauce beautifully.
• Fresh Thyme (chopped) – Provides an earthy aroma; dried thyme works too, but use less (1/3 amount).
• All-Purpose Flour – Thickens the cheese sauce; for gluten-free, try cornstarch or a gluten-free flour blend.
• Milk – Whole milk makes for a richer sauce; almond or soy milk can substitute, though the sauce might differ in texture.
• Gruyere Cheese – Offers nutty creaminess; Swiss cheese or a mozzarella-parmesan blend can be used instead.
• Ground Nutmeg – A dash adds warmth and enhances that cheesy flavor profile.
• Salt & Pepper – Essential for seasoning each delicious layer of potatoes.

Step‑by‑Step Instructions for Rich Potato Gratin
Step 1: Preheat Oven
Start by preheating your oven to 350°F (175°C). This temperature is perfect for achieving a creamy interior while ensuring the top gets a nice golden crust. Once the oven is warm and ready, you can focus on prepping your ingredients for this delicious Rich Potato Gratin.
Step 2: Prepare Potatoes
Wash and peel the starchy potatoes, then slice them into 1/8-inch rounds for even cooking. A mandoline slicer works great for this task, ensuring uniform thickness. After slicing, set the potato rounds aside in a bowl to prevent browning while you prepare the sauce.
Step 3: Prep Sauce Base
In a medium saucepan, melt 4 tablespoons of unsalted butter over medium heat. Once melted, add 1 minced onion, 2 cloves of grated garlic, and 2 teaspoons of fresh chopped thyme. Sauté the mixture for about 3-5 minutes until the onion becomes translucent and fragrant, forming the flavorful base for your gratin.
Step 4: Make Roux
Sprinkle ¼ cup of all-purpose flour over the sautéed onion mixture, stirring continuously for 1 minute. This creates a roux that will help thicken your cheese sauce. Gradually whisk in 3 cups of whole milk, ensuring there are no lumps. Continue cooking for 1-2 minutes until the sauce thickens slightly, taking care to keep it smooth.
Step 5: Add Cheese
Remove the saucepan from heat and stir in 2 cups of grated gruyere cheese, along with a pinch of ground nutmeg, salt, and pepper to taste. Keep stirring until the cheese melts completely and the sauce is creamy and rich. This cheese sauce is what makes your Rich Potato Gratin deliciously indulgent.
Step 6: Layer Gratin
Butter a baking dish, then spread a thin layer of the cheese sauce on the bottom. Arrange half of the sliced potatoes in an even layer over the sauce. Pour half of the remaining cheese sauce over the potatoes, then repeat with the second half of the potatoes, finishing with the last layer of sauce on top.
Step 7: Top with Cheese
To achieve a wonderfully crispy top, generously sprinkle the remaining 1 cup of gruyere cheese over the surface of the gratin. This will create a deliciously golden crust during baking that everyone will love when they dive into your Rich Potato Gratin.
Step 8: Bake
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 45-60 minutes until the potatoes are tender (you can check with a fork). For the last 15-20 minutes of baking, remove the foil to let the top turn bubbly and golden brown.
Step 9: Rest
Once baked to perfection, remove the gratin from the oven and let it rest for about 10 minutes. This cooling time allows the layers to set and makes it easier to slice and serve your inviting Rich Potato Gratin to family and friends.

Rich Potato Gratin Recipe FAQs
What type of potatoes should I use for potato gratin?
I recommend using starchy potatoes like Russets for their creamy texture, or Yukon Golds for a more buttery flavor. Russets break down beautifully, while Yukon Golds provide a lovely, rich taste.
How should I store leftover potato gratin?
Leftover potato gratin can be stored in an airtight container in the refrigerator for up to 4 days. Make sure it cools completely before sealing to maintain its creamy texture.
Can I freeze potato gratin for later use?
Absolutely! You can freeze your baked potato gratin for up to 3 months. Portion it into freezer-safe containers, leaving some space at the top for expansion. Just thaw it in the fridge overnight when you’re ready to enjoy it.
I’m worried about my potato gratin becoming watery. What can I do?
Great question! To avoid a watery gratin, ensure you’re slicing your potatoes uniformly and spreading them evenly in each layer. Also, be sure to season each layer with salt and pepper to draw out excess moisture. Covering the dish with foil during the first half of baking helps retain moisture, after which you can uncover it to allow for a crispy top.
Is potato gratin suitable for gluten-free diets?
Yes! If you need a gluten-free option, simply substitute the all-purpose flour with cornstarch or a gluten-free flour blend when making the roux for the cheese sauce. It will thicken just as well without the gluten.
Can I add other ingredients to my potato gratin?
Very much so! You can personalize your Rich Potato Gratin by adding sautéed vegetables like spinach or mushrooms or mixing different cheeses, such as cheddar or feta, for added flavor. The more, the merrier—feel free to get creative!
