Step‑by‑Step Instructions for Creamy Cheesy Potato Gratin
Step 1: Prepare Potatoes
Begin by preheating your oven to 350°F (175°C) for the perfect bake later. Using a mandoline or sharp knife, thinly slice your starchy potatoes, aiming for about 1/8-inch thickness. This ensures they cook evenly and meld beautifully with the creamy sauce. Once sliced, set them aside in a bowl of cold water to prevent browning.
Step 2: Make Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of unsalted butter. If you’re opting for the creamy sauce, stir in 2 cups of heavy cream and 1 cup of milk, along with minced garlic, thyme, salt, and pepper. Heat gently until well combined and steaming, but do not boil. If you prefer béchamel, create a roux by whisking in ¼ cup of flour and slowly adding 3 cups of milk until thickened and bubbling.
Step 3: Combine Sauce and Cheese
Once your sauce reaches a gentle simmer and thickens to your desired consistency, remove it from heat. Gradually mix in about 2 cups of grated Gruyère cheese, stirring consistently until the cheese melts completely and creates a rich, enticing sauce. This creamy cheesy mixture is the heart of your potato gratin, giving it that mouthwatering flavor.
Step 4: Layer Ingredients
In a greased 9×13-inch baking dish, arrange a layer of your soaked potato slices, slightly overlapping them for even coverage. Carefully pour a portion of your creamy cheesy sauce over the potatoes, followed by a sprinkling of extra cheese. Repeat the layering process until you exhaust all ingredients, finishing with sauce and a generous topping of cheese for that golden crust.
Step 5: Bake to Perfection
Place the assembled gratin into your preheated oven and bake for 60-70 minutes. You’re looking for a bubbly, golden top with tender potatoes; if the top browns too fast, cover it loosely with foil. Allow your kitchen to be filled with the irresistible aroma of baking creamy cheesy potato gratin as it cooks.
Step 6: Finish and Serve
After the gratin is baked to a flawless golden brown, remove it from the oven and let it cool for about 10-15 minutes. This resting period allows the layers to set, making it easier to slice. Top with freshly chopped parsley for a delightful pop of color and serve warm, allowing everyone to enjoy every creamy, cheesy bite.

Make Ahead Options
These creamy cheesy potato gratin are perfect for meal prep enthusiasts!

This way, you’ll have a deliciously comforting dish with minimal effort on busy weeknights, ensuring you enjoy every cheesy bite just as if it were freshly made!
Expert Tips for Creamy Cheesy Potato Gratin
- Slice Evenly: Use a mandoline for perfectly uniform potato slices. This ensures that everything cooks evenly and melds beautifully in your creamy cheesy potato gratin.
- Let It Rest: After baking, allow the gratin to rest for 10-15 minutes before slicing. This helps the layers to set and makes serving smoother.
- Watch the Seasoning: Be mindful not to over-season, especially if using a salty cheese like Gruyère. Taste your sauce before adding extra salt to ensure balanced flavors.
- Cheese Choice: Experiment with different cheeses, but if you want classic creaminess, stick with Gruyère. A blend of cheeses can add a unique flavor twist to your gratin.
- Cover if Necessary: If the top browns too quickly while baking, cover with foil to prevent burning. Remove the cover towards the end to achieve that golden crust.

Creamy Cheese Potato Gratin Recipe FAQs
What type of potatoes should I use for the best texture?
Using starchy potatoes like Russets is highly recommended for this dish, as they break down nicely to create a creamy texture. Waxy potatoes can lead to a firmer gratin that may not blend as well with the sauce.
How should I store leftovers of the gratin?
Refrigerate any leftovers in an airtight container for up to 3 days. When you’re ready to indulge again, gently reheat in the oven at 350°F (175°C) for optimal warmth and to maintain that luxurious creamy texture.
Can I freeze creamy cheesy potato gratin?
Yes! For long-lasting delight, allow your gratin to cool completely, then store it in a freezer-safe dish covered tightly with plastic wrap and aluminum foil. It will stay fresh for up to 2 months.
How do I reheat frozen gratin successfully?
To reheat your frozen creamy cheesy potato gratin, first, transfer it to the refrigerator and let it thaw overnight for the best texture. Once thawed, preheat your oven to 350°F (175°C) and bake for about 25-30 minutes, or until it’s hot and bubbling through the center.
Can I make substitutions for dietary preferences?
Absolutely! If you’re sensitive to dairy, consider using non-dairy milk and cheese alternatives. For a gluten-free option, replace the flour in the béchamel with cornstarch. Different cheeses such as cheddar or mozzarella can be used based on your taste preference.
What if my gratin is browning too quickly during baking?
Should you notice your gratin top developing too much color too soon, simply cover it loosely with foil for the remainder of the baking time. This will protect it from burning while still allowing the ingredients to cook evenly underneath.
