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 and wrap in foil. Roast in the oven for about 30-35 minutes until soft and golden. Once cool, squeeze out the roasted garlic into a bowl and mash.

Step 2: Prepare the Cream Mixture

In a 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 the potatoes. Then sprinkle half of the Swiss and cheddar cheeses on top. Repeat with remaining potatoes, cream mixture, and cheeses.

Step 4: Bake the Dish

Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 20-25 minutes until the potatoes are tender and the top is golden and bubbly.

Step 5: Garnish and Serve

Let the dish sit for 10 minutes before serving. Garnish with freshly chopped parsley for a pop of color. Enjoy as a delicious side dish to any meal!

Common Mistakes to Avoid
