- All-purpose flour (¼ cup): Thickens the sauce into a luscious, velvety consistency.
- Low-sodium chicken broth (1 cup): Enhances the sauce with umami and keeps it light.
- Whole milk or half and half (2 cups): Creates the signature creamy texture that coats every slice of potato.
- Salt (½ teaspoon) and black pepper (½ teaspoon): Essential seasoning that balances and elevates the flavors.
- Fresh thyme, chopped (1 tablespoon): Bright herbaceous garnish that adds a lovely aroma at the end.
- Yukon Gold potatoes (3 pounds): Their natural buttery flavor and creamy texture make them ideal for this recipe.

How to Make Potatoes Au Gratin Recipe
Step 1: Preheat and Prep
Start by setting your oven to 350°F (175°C), creating the perfect environment to slowly bake your layers of creamy goodness. Lightly grease a 9×13 inch casserole dish with cooking spray to ensure every bite comes out smoothly without sticking, making clean-up a breeze.
Step 2: Sauté Vegetables
In a skillet over medium-low heat, melt the butter until it’s warm and inviting. Add the chopped onion and minced garlic, gently cooking until they soften and release their fragrant aroma. This step builds the flavor foundation for the sauce. Sprinkle in the flour, stirring constantly for about 2 minutes to cook out the rawness and create a light roux that will thicken your sauce beautifully.
Step 3: Make the Sauce
Slowly pour in the chicken broth and milk while whisking continuously, guaranteeing a smooth, lump-free sauce. Bring it to a gentle boil over medium heat, stirring consistently, so the sauce develops that perfect creamy texture. Season with salt and black pepper to taste, balancing the richness and setting the flavor stage for the potatoes to shine.
Step 4: Layer Your Dish
In your prepared casserole, lay down one-third of the sliced potatoes in an even layer. Pour over a third of the velvety sauce and sprinkle half a cup of the sharp cheddar cheese. Repeat this layering process twice more until all the potatoes and sauce are used up. Finish by scattering the freshly grated Parmesan cheese on top, promising that irresistible, golden crust after baking.
Step 5: Bake to Perfection
Cover the casserole dish with aluminum foil to trap moisture and bake for 45 minutes, allowing the potatoes to soften and the flavors to meld. Remove the foil and bake for another 45 minutes until the cheese is beautifully golden and bubbling, and the potatoes are tender to the fork. If you’re craving an extra golden finish, a quick broil for a few minutes will give you that perfect gratin crust.
Step 6: Serve and Enjoy
Once out of the oven, sprinkle the chopped fresh thyme over the top. This simple addition brightens the dish with a subtle herbal note and adds an inviting pop of color. Serve your Potatoes Au Gratin Recipe hot, and prepare for delighted compliments and seconds.

Garnishes
Adding fresh thyme is a classic touch that elevates the dish with its fragrant, woody flavor. You might also try a sprinkle of finely chopped chives or a dash of smoked paprika for an unexpected twist. These simple garnishes not only enhance taste but also add to the visual appeal at the table.
Side Dishes
Potatoes Au Gratin Recipe pairs beautifully with a variety of dishes. Serve alongside roasted chicken or a juicy steak for a hearty meal, or complement it with steamed green beans or a crisp garden salad to balance the richness. Its versatility means it can anchor your dinner plate effortlessly.
Creative Ways to Present
For a stunning presentation, bake individual portions in ramekins for a personalized touch that’s perfect for dinner parties. You can also layer thinner slices of potato in a circular pattern for an elegant spiral that impresses visually before the first bite. Either way, this recipe’s creamy texture and golden top make it a feast for the eyes as well as the palate.
Make Ahead and Storage
Storing Leftovers
If you have leftovers—and you probably will—store them in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen after a day, making it a fantastic make-ahead option for quick dinners.
Freezing
Freezing your Potatoes Au Gratin Recipe is possible but not ideal for maintaining the cheese’s original creamy texture. If you choose to freeze, cover the casserole tightly with plastic wrap and foil, and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheating
Reheat leftovers gently in the oven at 325°F (160°C) for about 20-25 minutes, covered loosely with foil to prevent the top from burning while warming through. This method keeps the potatoes tender and the cheese melty, reviving the magic of the original bake.
FAQs
Can I use other types of potatoes for this recipe?
Absolutely! Yukon Gold potatoes are recommended for their creamy texture and buttery flavor, but Russets or red potatoes can also work. Be mindful that the texture and cooking time might vary slightly depending on the potato variety.
Is it possible to make this recipe vegetarian?
Yes, simply substitute the chicken broth with vegetable broth to keep the rich flavor while making it fully vegetarian. This switch doesn’t compromise the creaminess or taste.
Can I make this dish gluten-free?
Definitely! Replace the all-purpose flour with a gluten-free flour blend or cornstarch to thicken the sauce. This adjustment ensures everyone can enjoy the deliciousness without losing any of the creamy charm.
How thin should I slice the potatoes?
The potatoes should be sliced about 1/8-inch thick. This thinness allows them to cook evenly and absorb the luscious sauce thoroughly, resulting in that melt-in-your-mouth texture everyone loves.
What’s the best cheese to use if I want a different flavor?
While white cheddar and Parmesan are fantastic, Gruyere or fontina are excellent substitutes that melt beautifully and add slightly different flavor profiles. Mixing cheeses can create a unique twist on the classic Potatoes Au Gratin Recipe.
