Step‑by‑Step Instructions for Cheesy Mashed Potato Gratin
Step 1: Prepare the Mashed Potatoes
Begin by peeling and dicing 1.5 kg of baking potatoes into equal pieces. Place them in a large pot, cover with cold, salted water, and bring to a boil over medium-high heat. Cook for about 15-20 minutes until the potatoes are knife-tender; they should easily break apart. Once cooked, drain and let sit for 1 minute to dry slightly.
Step 2: Make the Mash
Return the drained potatoes to the pot and add 6 tablespoons of room-temperature butter and 160 ml of warmed cream. Mash them together until smooth and creamy, ensuring no lumps remain. Stir in 150 g of grated cheddar cheese and season with salt and 1/4 teaspoon of black pepper, mixing well until the cheese is melted and fully incorporated.
Step 3: Preheat the Oven
While you prepare the gratin topping, set your oven to preheat at 200°C (400°F). This temperature is crucial for achieving that perfect golden crust on the top layer of your cheesy mashed potato gratin. Make sure your oven is fully preheated before you start assembling the dish for even cooking.
Step 4: Assemble the Gratin
Take 750 g of baking potatoes and peel them before slicing them into thin half-moons. In a mixing bowl, melt 2 tablespoons of butter and combine it with 1 minced garlic clove, a pinch of salt, and additional black pepper. Toss the sliced potatoes in this mixture along with half of the 40 g of diced Parmesan, ensuring all slices are evenly coated for flavor.
Step 5: Layer
In a baking dish, spoon the creamy mashed potatoes and spread them out evenly to create a smooth layer. Next, layer the garlic buttered potato slices on top of the mash, stacking them at a slight angle for an appealing presentation. Press down gently to ensure the layers meld together, showcasing the texture of the cheesy mashed potato gratin.
Step 6: Bake with Foil
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow the flavors to meld. After this, carefully remove the foil and sprinkle the remaining Parmesan evenly over the top. Return to the oven and bake uncovered for an additional 40 minutes, or until the top is golden brown and crispy.
Step 7: Rest Before Serving
Once out of the oven, let the cheesy mashed potato gratin rest for 15-20 minutes. This resting period allows the layers to set, making it easier to serve. Just before serving, garnish with freshly chopped chives for a pop of color and a fresh touch. Enjoy the delightful combination of creamy mash and crispy topping!
Make Ahead Options
Preparing the Cheesy Mashed Potato Gratin ahead of time is a fantastic way to save precious minutes on busy weeknights! You can make the mashed potatoes up to 24 hours in advance; simply prepare as directed, cool them completely, and store in an airtight container in the refrigerator. The gratin topping can also be assembled ahead, covering the dish tightly with foil or plastic wrap to keep everything fresh. When ready to serve, layer the mashed potatoes into the baking dish and top with the prepared gratin layer. Bake as usual, adding an extra 10-15 minutes to ensure it’s heated through and the top is gloriously crispy. Enjoy a delicious, stress-free meal that feels like a treat!
