How to Make Roasted Garlic Potatoes au Gratin
Step 1: Roast the Garlic
Preheat your oven to 400°F (200°C). Cut the top off the head of garlic to expose the cloves. Drizzle with olive oil, wrap in foil, and roast in the oven for about 30-35 minutes or until soft and golden. Once cool, squeeze out the roasted garlic into a bowl and mash.
Step 2: Prepare the Cream Mixture
In a mixing bowl, combine the heavy cream, whole milk, mashed roasted garlic, salt, pepper, thyme, and paprika. Whisk until well blended.
Step 3: Layer the Potatoes
In a greased 9×13 inch baking dish, layer half of the sliced potatoes evenly. Pour half of the cream mixture over them. Then sprinkle half of both Swiss and cheddar cheeses on top. Repeat this process with the remaining potatoes, cream mixture, and cheeses.
Step 4: Bake the Dish
Cover your baking dish with aluminum foil and bake in the preheated oven for 45 minutes. Afterward, remove the foil and bake for an additional 20-25 minutes until the potatoes are tender and the top is golden brown and bubbly.
Step 5: Garnish and Serve
Let your dish sit for about 10 minutes before serving. Garnish with freshly chopped parsley to add a pop of color. Enjoy your delicious side dish!
