- ½ teaspoon black pepper: Adds a gentle spice that livens the dish up.
- ½ teaspoon paprika: Contributes a hint of smokiness and color to the potatoes.

How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish generously with butter. This ensures your gratin won’t stick and helps the edges become deliciously crisp.
Step 2: Slice the Potatoes
Wash the Yukon Gold potatoes thoroughly, then slice them thinly—about 1/8 inch thick is perfect. To keep the slices from browning, place them in a bowl of cold water until you’re ready to assemble.
Step 3: Sauté Onions and Garlic
In a medium skillet, melt the butter over medium heat. Add the finely chopped onion and sauté until it turns translucent and soft. Then stir in the minced garlic, cooking for about one minute until fragrant. This step unlocks a wonderful aroma and deep flavor that will infuse the gratin.
Step 4: Mix the Cream Base
In a large bowl, combine the heavy cream with salt, black pepper, paprika, and thyme. Whisk everything together until well blended. This creamy mixture will soak into the potatoes and make every bite silky and flavorful.
Step 5: Layer the Ingredients
Drain the potato slices and start layering them in half within your prepared baking dish. After the first layer, spread half of the sautéed onion and garlic mixture over the potatoes, then sprinkle with one cup of the combined shredded cheddar and Gruyère cheeses. Repeat with the remaining potato slices, onions, garlic, and cheese for a perfect layered effect.
Step 6: Pour and Bake
Pour the cream mixture evenly over the layered potatoes, making sure each slice gets coated with the rich, herbed cream. Cover the dish tightly with foil and bake for 30 minutes. After that, remove the foil and bake for another 15-20 minutes, until the top is golden, bubbly, and irresistibly crispy.
Step 7: Rest and Garnish
Once baked, remove the dish from the oven and let it cool for about 10 to 15 minutes. This resting time helps the dish settle and makes serving easier. Finish by sprinkling freshly chopped parsley over the gratin, adding a pop of color and freshness.
How to Serve Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe

Garnishes
Fresh parsley is the classic choice for garnishing Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe, providing a vibrant green contrast that brightens the warm, golden casserole. For an extra touch of indulgence, sprinkle some extra shredded cheese or a few crispy fried onions on top right before serving.
Side Dishes
This gratin pairs beautifully with roasted meats like chicken, beef, or pork. A crisp green salad or steamed vegetables add a refreshing balance to this indulgently cheesy dish. You can also serve it alongside grilled asparagus or sautéed green beans for some crunch and color.
Creative Ways to Present
Serve individual portions in small ramekins for a charming, restaurant-style presentation that’s perfect for dinner parties. You can also sprinkle a pinch of smoked paprika or even chopped chives on top for a subtle makeover that enhances both look and flavor.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe in an airtight container in the refrigerator. It will stay fresh for up to 3-4 days, making it a great option for easy reheats later in the week.
Freezing
You can freeze the gratin either before baking or after cooling completely. Wrap it tightly in foil and place it in a freezer-safe container. It should last well for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
The best way to reheat is in the oven at 350°F (175°C) until warmed through and bubbly, usually about 20-25 minutes. This ensures the top remains crispy and the cheese melts beautifully again. Microwaving is quicker but might lose that lovely crust.
FAQs
Can I use a different type of potato?
While Yukon Gold potatoes are ideal for their creamy texture and mild flavor, you can substitute with Russet potatoes. Just keep in mind they’re starchier and may produce a slightly different texture—still delicious though!
Is it possible to make this recipe dairy-free?
This recipe relies heavily on cream and cheese for its signature taste. For a dairy-free version, you’d need to use plant-based cream substitutes and vegan cheese alternatives, but the final taste and texture will differ from the original.
How long does it take to prepare and cook?
Overall, prep time is around 15 minutes with about 45-50 minutes of baking. The layering and sautéing steps are straightforward and come together quickly, so it’s a manageable recipe even on busy days.
Can I prepare Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe ahead of time?
Absolutely! You can assemble the gratin a few hours before baking and refrigerate it until you’re ready to cook. Just add extra baking time if baking straight from the fridge to ensure it heats through evenly.
What cheese substitutes can I use if I don’t have Gruyère?
If you can’t find Gruyère, Swiss cheese or Emmental are excellent substitutes that melt well and offer a similar nutty flavor. A mild mozzarella could be used in a pinch, but it won’t have quite the same richness.
Final Thoughts
Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe is truly a treasure in the world of comfort foods. Its perfect layers of creamy potatoes and melted cheese deliver a taste that’s both nostalgic and exciting. I highly encourage you to try it for your next family dinner or special occasion—you’ll be amazed at how this humble dish can steal the spotlight and bring everyone back for seconds.
