Step‑by‑Step Instructions for Roasted Garlic Potatoes au Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). A hot oven will set the stage for perfectly roasted garlic and tender potatoes. This ensures that when you're ready to bake your Roasted Garlic Potatoes au Gratin, the heat is just right to create that golden, bubbly top.
Step 2: Roast the Garlic
Cut the top off a head of garlic to expose the cloves. Drizzle with olive oil, wrap it in foil, and place it in the oven. Roast for about 30–35 minutes until the garlic becomes soft and golden brown. Once done, let it cool slightly before squeezing the roasted cloves into a bowl to mash them.
Step 3: Prepare the Cream Mixture
In a medium mixing bowl, combine 1 cup of heavy cream, 1 cup of whole milk, the mashed roasted garlic, salt, black pepper, thyme, and paprika. Whisk the mixture until it’s smooth and well blended, ensuring all the flavors meld together beautifully for your Roasted Garlic Potatoes au Gratin.
Step 4: Layer the Potatoes
Grease a 9x13 inch baking dish with light oil or cooking spray. Start layering half of the thinly sliced Yukon Gold potatoes evenly across the bottom. Pour half of the cream mixture over the potatoes, then sprinkle half of the Swiss and cheddar cheeses on top, creating a delicious creamy, cheesy layer.
Step 5: Repeat the Layering
Add the remaining sliced potatoes to the dish, layering them neatly. Pour the rest of the cream mixture over the potatoes, ensuring they’re well coated. Finish by generously sprinkling the remaining Swiss and cheddar cheeses on top. This ensures a rich flavor in your Roasted Garlic Potatoes au Gratin.
Step 6: Bake Covered
Cover the baking dish tightly with aluminum foil to trap in moisture. Place it in the preheated oven and bake for 45 minutes. This covered baking will soften the potatoes, making them tender and allowing them to absorb all the delicious flavors.
Step 7: Bake Uncovered
After the initial 45 minutes, carefully remove the foil. Return the baking dish to the oven and bake uncovered for an additional 20–25 minutes. Look for the top to turn golden brown and bubbly, giving it that appetizing finish typical of Roasted Garlic Potatoes au Gratin.
Step 8: Let It Rest
Once out of the oven, let the dish sit for about 10 minutes before serving. This resting time helps the layers settle and firm up a bit, making serving easier. Just before serving, garnish your wonderfully comforting Roasted Garlic Potatoes au Gratin with freshly chopped parsley for a touch of color and flavor.

Roasted Garlic Potatoes au Gratin Recipe FAQs
How do I choose the best potatoes for this recipe?
When it comes to making Roasted Garlic Potatoes au Gratin, Yukon Gold potatoes are my top recommendation! They have a creamy texture that pairs beautifully with the rich, cheesy filling. Look for firm potatoes with smooth skin and avoid those with dark spots or blemishes, as this can indicate overripeness.
What is the best way to store leftovers?
Absolutely! Once your Roasted Garlic Potatoes au Gratin has cooled completely, you can store it in the fridge. Just cover it tightly with plastic wrap or aluminum foil to keep it fresh. It’ll last about 3 days, so you can enjoy those creamy bites for a few extra meals!
Can I freeze Roasted Garlic Potatoes au Gratin?
Yes, you can! First, let the dish cool completely. Then, portion it into airtight containers or wrap it tightly in aluminum foil or plastic wrap. You can freeze it for up to 3 months! When you're ready to enjoy it, simply thaw overnight in the fridge and reheat as outlined to bring back that lovely cheesy goodness.
What should I do if my potatoes are not cooking evenly?
If you find that some of your potatoes are undercooked while others are mushy, it’s likely due to uneven slicing. Make sure each potato slice is about ⅛ inch thick for consistent cooking. If you’ve already baked it and some parts are still hard, cover the dish with foil and bake a bit longer at 350°F (175°C) until they’re tender.
Are there any dietary considerations with this recipe?
This Roasted Garlic Potatoes au Gratin contains dairy, so it’s not suitable for those with lactose intolerance or dairy allergies. However, you can make a non-dairy version by substituting the heavy cream and milk with almond or coconut milk and using dairy-free cheese. For those with nut allergies, opt for specially formulated plant-based creams and cheeses. Always be sure to check labels!
How do I know when the dish is done baking?
Great question! To check if your Roasted Garlic Potatoes au Gratin is ready, look for a bubbly and golden brown top. The potatoes should be tender when pierced with a fork, typically after removing the foil for the final 20-25 minutes of baking. If the top isn’t browning as expected, you can turn on the broiler for a minute or two—just keep an eye on it to prevent burning!
