Cheesy Hasselback Potato Gratin Ingredients

For the Gratin
• Salted Butter – Adds richness and helps prevent sticking. Substitute with olive oil for a dairy-free option.
• Heavy Cream – Provides creaminess and thickness to the sauce. Use half-and-half for a lighter version, but avoid non-dairy substitutes as they might curdle.
• Garlic – Enhances flavor with aromatic notes. Substitute with garlic powder if fresh is not available.
• Fresh Rosemary, Sage, and Thyme – Add aromatic herbal flavors. Use dried herbs if fresh is unavailable but reduce the amount to 1/3.
• Dijon Mustard – Adds a slight tanginess that balances the richness. Can be omitted for a milder taste.
• Nutmeg – A subtle spice that enriches the flavor profile. Omit if not available.
• Kosher Salt and Black Pepper – Enhances overall flavor. Use other salts if preferred, adjusting the quantity to taste.
• Gruyere Cheese, Fontina Cheese, Parmesan Cheese – Three-cheese blend creates a depth of flavor and gooey texture. Replace with similar melting cheeses like mozzarella or cheddar if necessary.
• Russet Potatoes – Essential for texture; starchy potatoes yield the best results. Yukon Gold can be a good substitute.

Step‑by‑Step Instructions for Cheesy Hasselback Potato Gratin

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). While the oven is warming up, take a moment to grease a 2-quart ceramic baking dish with softened salted butter to prevent the gratin from sticking later on.

Step 2: Grate Cheese
Next, finely shred your Gruyere, Fontina, and Parmesan cheeses. Set aside 1 cup of the shredded blend, as you’ll need it for the final layer of this delicious Cheesy Hasselback Potato Gratin. The rest will get mixed into the sauce, adding that irresistible gooeyness.

Step 3: Prepare Sauce
In a large mixing bowl, whisk together heavy cream, minced garlic, chopped fresh rosemary, sage, thyme, Dijon mustard, nutmeg, kosher salt, and black pepper. Once well combined, fold in 5 cups of your shredded cheese mixture until the ingredients mingle beautifully, creating a rich, creamy sauce.

Step 4: Slice Potatoes
Peel your russet potatoes and thinly slice them to about 1/8 inch thick for even cooking. Toss the potato slices in the creamy mixture, ensuring that each slice is well-coated in the luscious sauce, which will infuse flavors throughout the dish.

Step 5: Layer Gratin
Now it’s time to arrange the potato stacks in your greased baking dish. Carefully layer the coated potato slices, overlapping slightly. Pour any remaining cream sauce over the top, making sure it distributes evenly to envelop the potatoes as they bake.

Step 6: Bake
Cover the dish tightly with aluminum foil and bake in your preheated oven for 40 minutes. After this time, remove the foil and continue baking for an additional 30 minutes until the potatoes are tender and the edges start to crisp up.

Step 7: Add Cheese and Finish Baking
After the initial baking, pull the dish out and sprinkle the reserved cup of cheese over the top. Pop it back into the oven for another 30 minutes, allowing the cheese to melt and form a bubbly, golden crust that beckons to be served.

Step 8: Rest Before Serving
Once baked to perfection, take the Cheesy Hasselback Potato Gratin out of the oven and let it rest for 20-30 minutes. This short cooling period allows the layers to set, making it easier to serve and enhancing the overall flavor.

Make Ahead Options

These Cheesy Hasselback Potato Gratin are perfect for meal prepping, allowing you to enjoy this rich and creamy dish without the last-minute rush! You can assemble the entire gratin up to 24 hours in advance; just cover it tightly with foil or plastic wrap and refrigerate. To maintain quality, make sure to let the dish reach room temperature before baking. When you’re ready to serve, preheat your oven and remove the cover, baking it according to the original instructions, ensuring that cheesy topping achieves that ideal golden-brown crust. This thoughtful prep not only saves time during busy holidays but guarantees a crowd-pleasing star of your festive table!

Helpful Tricks for Cheesy Hasselback Potato Gratin

Even Slicing: Use a mandoline slicer for uniform potato thickness, ensuring even cooking and that perfect creamy consistency in your Cheesy Hasselback Potato Gratin.
Hand-Grated Cheese: Grate your cheeses by hand rather than using pre-shredded packs. Freshly grated cheese melts better and enhances the overall texture of the dish.
Avoid Low-Fat Cream: Stick to heavy cream instead of low-fat options, preventing curdling in your sauce. The richness of cream is vital for the creamy, decadent layers.
Choose the Right Bakeware: Opt for a ceramic baking dish instead of glass to ensure even heat distribution, yielding perfectly baked potatoes and a deliciously golden crust.
Rest the Gratin: Allow the dish to rest for 20-30 minutes after baking. This cooling period helps the layers firm up for easier serving and a more delightful mouthfeel.
