Embrace the magic of Potatoes Au Gratin with these simple ingredients, and get ready to create an unforgettable dish! Step‑by‑Step Instructions for Potatoes Au Gratin Step 1: Infuse the Cream Begin by combining 1 finely chopped shallot, 2 cloves of minced garlic, 4 sprigs of fresh thyme, 2 cups of heavy cream, and 1 cup of whole milk in a saucepan. Heat mixture over medium-low heat, allowing it to simmer gently for about 30 minutes. Stir occasionally and watch for the cream to thicken slightly and the aromatics to infuse beautifully, filling your kitchen with a comforting scent. Step 2: Prepare the Potatoes While the cream infuses, peel and thinly slice 2 to 3 Yukon Gold potatoes (around 2 pounds) to about 1/8 inch thick. Utilize a mandoline for even slices, if available, to ensure consistent cooking later. Once sliced, keep the potatoes at room temperature to avoid browning and to maintain their fresh appearance until ready to combine with the cream sauce. Step 3: Combine and Cook the Potatoes Once infused, strain the cream mixture back into the saucepan, discarding the solids. Add the sliced potatoes and 1 teaspoon of kosher salt to the warm cream. Cook over medium heat for about 4 to 5 minutes until the potatoes are tender but not fully cooked; they should be easily pierced with a fork. This step ensures the potatoes absorb that rich flavor before layering. Step 4: Layer the Ingredients Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with unsalted butter, then begin layering the dish. Start with a layer of potatoes, followed by a spoonful of the creamy mixture, a sprinkle of 1 cup of Gruyère cheese, and some fresh thyme. Repeat this layering process until you’ve used all the ingredients, finishing with a top layer of cream and cheese. Step 5: Bake the Gratin Once layered, place the baking dish in the preheated oven and bake uncovered for 40 to 50 minutes. Keep an eye on it until the surface becomes golden brown and bubbling delightfully. The edges should look crispy, while the center remains creamy, promising a beautifully rich flavor with each bite of your luxurious Potatoes Au Gratin. Step 6: Let it Rest After baking, remove the Potatoes Au Gratin from the oven and allow it to rest for about 5 to 10 minutes before serving. This resting time allows the dish to set slightly, creating a perfect consistency for serving. As you cut into this decadent creation, enjoy the rich aroma and the beautiful layers that make every bite a comforting indulgence. What to Serve with Creamy Potatoes Au Gratin?

Expert Tips for Potatoes Au Gratin Use a Mandoline Safely: Always utilize the safety guard when slicing potatoes to ensure even thickness and keep your fingers safe during prep.

Even Cooking: Ensure all potato slices are uniformly cut to guarantee they cook evenly and create that perfect creamy texture in your Potatoes Au Gratin.

Potatoes Au Gratin Recipe FAQs What type of potatoes are best for Potatoes Au Gratin? I recommend using Yukon Gold potatoes as they hold their shape well and have a creamy texture that complements the dish beautifully. If you prefer, you can use Russet potatoes, but they may create a slightly different texture due to their starch content. How should I store leftover Potatoes Au Gratin? Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Just make sure to let the dish cool completely before sealing it to maintain its creamy consistency and flavor. Can I freeze Potatoes Au Gratin? Absolutely! To freeze, wrap your cooled Potatoes Au Gratin tightly in plastic wrap and then in aluminum foil. This method helps to avoid freezer burn. You can keep it in the freezer for up to 2 months. When you’re ready to enjoy, thaw it in the fridge overnight and reheat it in the oven at 350°F for about 20-30 minutes. What can I do if my potatoes remain hard after baking? If your potatoes are still hard after baking, it often means they were sliced too thickly or not cooked long enough in the cream before layering. Next time, try slicing them thinner (about 1/8 inch) and ensuring they simmer in the cream until fork-tender for optimal tenderness. Can I make Potatoes Au Gratin without dairy? Yes! If you’re looking for a dairy-free alternative, you can use coconut milk or a cashew cream for the sauce, and substitute nutritional yeast for the cheese to give it a cheesy flavor without using actual cheese. This way, everyone can enjoy a delicious version of Potatoes Au Gratin! Is it okay to add other ingredients to the recipe? Very!
