Easy Potato Gratin Ingredients
• A delightful blend of flavors awaits!
For the Gratin
- Starchy Potatoes (Russets or Yukon Golds) – Russets are perfect for a creamy texture; Yukon Golds add a buttery flavor.
- Butter – Unsalted is best to control the saltiness in your dish.
- Onion (minced) – Adds depth and a touch of sweetness; shallots can be a milder substitute.
- Garlic (grated) – Fresh garlic enhances the overall flavor, giving it a beautiful aroma.
- Fresh Thyme (chopped) – Adds herbal notes; dried thyme can also work in a pinch.
- Flour – Essential for thickening your rich cheese sauce, preventing lumps!
- Milk – Whole milk creates a luscious, creamy base; skim milk can be too thin.
- Gruyere Cheese (shredded) – A must for its rich, nutty flavor; feel free to substitute Swiss or Cheddar.
- Ground Nutmeg – Just a pinch enhances the cheese flavor, making it more complex.
- Salt and Pepper – Essential for seasoning; remember to season each layer for the best flavor!
Step‑by‑Step Instructions for Easy Potato Gratin
Step 1: Preheat the Oven
Begin your adventure with Easy Potato Gratin by preheating your oven to 350°F (175°C). This step is crucial for achieving that beautifully golden top. Set the temperature and allow your oven to warm up as you prepare the potatoes and rich cheese sauce.
Step 2: Prepare the Potatoes
While the oven heats, slice your starchy potatoes—Russets or Yukon Golds—into 1/8-inch rounds using a mandoline for uniform thickness. This ensures even cooking and a tender texture throughout. Place the potato slices in a bowl of water to prevent browning as you continue with the recipe.
Step 3: Sauté Aromatics
In a medium saucepan, melt 4 tablespoons of unsalted butter over medium heat. Add the minced onion and sauté for about 3-5 minutes, stirring occasionally, until it’s softened and translucent. Then, stir in the grated garlic and chopped fresh thyme, allowing their delightful aromas to fill your kitchen for another minute.
Step 4: Create the Roux
Sprinkle 3 tablespoons of flour over the sautéed mixture, stirring continuously for about 1 minute to form a roux. This will help thicken your cheese sauce later. Be sure to keep the heat at medium to avoid burning the flour while constantly stirring until it turns a light golden color.
Step 5: Make the Cheese Sauce
Gradually whisk in 2 cups of whole milk, cooking the mixture for 1-2 minutes until it thickens. You’ll know it’s ready when the sauce coats the back of a spoon. Remove the saucepan from heat and stir in ½ cup of shredded Gruyere cheese, a pinch of ground nutmeg, salt, and pepper until melted and smooth for that rich gratin flavor.
Step 6: Assemble the Gratin
Pour a thin layer of the creamy cheese sauce into the bottom of a buttered 9×13-inch baking dish. Layer half of the potato slices evenly over the sauce, followed by half of the remaining cheese mixture. Repeat the process with the remaining potato slices and sauce, creating a deliciously layered Easy Potato Gratin.
Step 7: Top with Cheese
Finish your assembly by topping the final layer of sauce with the remaining 1 cup of shredded Gruyere cheese. This will create the perfect melted, bubbly topping that is the hallmark of any great potato gratin. Ensure the cheese is evenly distributed for a beautifully caramelized finish during baking.
Step 8: Bake the Gratin
Cover your baking dish with aluminum foil, and place it in the preheated oven. Bake for 45-60 minutes, or until the potatoes are tender and the layers meld beautifully together. Check for doneness by inserting a knife into the center—it should slide in easily.
Step 9: Broil for a Finish
Optional, but highly recommended! After the initial baking, remove the foil and switch your oven to the broil setting. Broil the gratin for an additional 2-3 minutes, watching carefully as the top turns a lovely golden brown and becomes slightly crispy.
Step 10: Rest Before Serving
Once out of the oven, allow the Easy Potato Gratin to cool for about 10 minutes. This resting period helps the layers to set and makes serving easier. Cut into squares, dish up, and relish in the comforting flavors you’ve created!
Expert Tips for Easy Potato Gratin
Slice Consistently: Aim for uniform 1/8-inch potato slices to ensure even cooking; a mandoline can guarantee thickness and save time.
Layer Wisely: Season each layer with salt and pepper to prevent bland spots in your easy potato gratin; even seasoning is key to flavor.
Cover While Baking: Use foil for the first 30-40 minutes of baking to allow the gratin to cook evenly, then uncover to achieve that perfect golden-brown top.
Whisk the Sauce: Thoroughly whisk flour into the butter mixture before adding milk to avoid lumps in your cheese sauce and ensure creaminess.
Resting Time Matters: Always let the gratin sit for 10 minutes before serving; this will help the layers set beautifully and make it easier to slice.

Reheating: Reheat your gratin in the oven at 350°F (175°C) for about 20-25 minutes, or until warmed through. Adding a splash of milk can revive creaminess.

Easy Potato Gratin Recipe FAQs
How should I select the potatoes for the gratin?
Absolutely! For the best results, choose starchy potatoes like Russets or Yukon Golds. Russets provide a creamy texture due to their high starch content, while Yukon Golds deliver a lovely buttery flavor. Look for potatoes that are firm with smooth skins and no dark spots or blemishes.
How do I store leftover potato gratin?
Store your leftover Easy Potato Gratin tightly covered in the fridge for up to 4 days. Make sure it’s in an airtight container to prevent it from drying out. If you want to enjoy it later, freezing is a great option!
Can I freeze Easy Potato Gratin?
Definitely! For freezing, I recommend portioning the gratin into individual servings, wrapping each tightly in plastic wrap, and then placing them in a freezer-safe bag. This way, you can easily grab a portion whenever you need it. It will last in the freezer for up to 3 months. To reheat, let it thaw overnight in the refrigerator, then bake at 350°F (175°C) for about 20-25 minutes until warmed through.
What should I do if my cheese sauce is lumpy?
If your cheese sauce turns out lumpy, don’t worry—there’s a way to save it! Begin by whisking the sauce vigorously to incorporate any clumps, and if that doesn’t work, you can blend it with an immersion blender to achieve a smooth texture. Remember, it’s all about that creamy consistency, so take your time and be patient!
Can I make any substitutions for the ingredients?
Very! Substitute Gruyere cheese with Cheddar or Fontina for a different flavor twist. If you’re keeping things dairy-free, consider using a non-dairy milk and cheese alternative. Additionally, feel free to add veggies like spinach or roasted garlic between layers to customize your gratin to your family’s liking!
Is this gratin suitable for kids?
Oh, definitely! Easy Potato Gratin is a family-friendly dish that most kids absolutely love, thanks to its creamy texture and comforting flavors. Just keep any dietary restrictiveness in mind, and you can customize it by swapping in vegetables or cheeses according to their tastes.
