How to Make Cheesy Scalloped Potatoes with Thyme Recipe

Step 1: Prep the Oven and Baking Dish

Start by heating your oven to 400°F and greasing a 9 x 13-inch baking dish with cooking spray. This simple step ensures your scalloped potatoes don’t stick and allows the edges to crisp beautifully while baking.

Step 2: Sauté the Onion and Garlic

Melt butter in a large sauté pan over medium-high heat. Add the thinly sliced onion and cook until soft and translucent, about 4-5 minutes. Then add minced garlic and cook for an extra 1-2 minutes until fragrant. This forms the flavorful base of your creamy sauce.

Step 3: Whisk in the Flour and Liquids

Sprinkle the flour evenly over the onions and garlic, stirring constantly to combine and cook out the rawness, about 1 minute. Slowly pour in the stock while whisking vigorously to avoid lumps. Add the milk, salt, pepper, and 1 teaspoon of fresh thyme, continuing to whisk until everything is smooth and the sauce starts to gently simmer and thicken—make sure it doesn’t boil.

Step 4: Layer the Potatoes and Cheese

Place half of the sliced potatoes evenly in the baking dish. Pour over half of the creamy sauce, straining out and adding the onions from your sauce for extra flavor and a smoother texture. Sprinkle with half of the cheddar and all of the Parmesan cheese. Repeat this layering with the remaining potatoes, sauce, and cheddar cheese to build those irresistible layers.

Step 5: Bake Covered

Cover the dish with aluminum foil and bake at 400°F for 30 minutes. This allows the potatoes to cook through gently and the sauce to bubble up, melding all the flavors wonderfully.

Step 6: Bake Uncovered Until Golden

Remove the foil and continue baking uncovered for another 25-30 minutes. The top will become beautifully golden, the cheese perfectly melted and slightly crisped, and the potatoes tender through and through.

Step 7: Cool and Garnish

Let the dish cool on a rack for a few minutes. Sprinkle the remaining teaspoon of thyme and extra Parmesan cheese on top for a fresh herb finish and added savory flavor that really brings the dish to life.

Step 8: Serve Warm and Enjoy

Serve these Cheesy Scalloped Potatoes with Thyme Recipe warm for the ultimate cozy side that everyone will rave about.

Make Ahead and Storage

Storing Leftovers

Leftovers can be tightly covered and refrigerated for up to 3 days. The flavors have time to meld, and a quick reheat will bring back that creamy, cheesy goodness.

Freezing

You can freeze the whole dish before baking or after cooking. Wrap tightly in foil and plastic wrap to prevent freezer burn, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat in the oven at 350°F, covered with foil, until warmed through, about 20-25 minutes. For crispy edges, remove the foil during the last 5 minutes.

FAQs

Can I use a different type of potato?

Absolutely! While Yukon Golds are ideal for their buttery texture and even cooking, Russets or red potatoes can work well too. Just slice them evenly for consistent baking.

Is it possible to make this recipe vegetarian?

Yes! Simply swap the chicken stock for vegetable stock, and all other ingredients remain the same for a delicious vegetarian version.

Can I add other herbs besides thyme?

Definitely. Rosemary, sage, or a mix of Italian herbs can add extra flavor dimension. Just be mindful of their potency compared to thyme.

How do I make this dish dairy-free?

Try using a dairy-free butter substitute, unsweetened plant-based milk, and vegan cheese alternatives. The texture might be slightly different, but it will still be tasty!

What’s the best cheese to use if I want a different flavor profile?

Gruyère or Fontina cheeses offer a nutty, creamy alternative that melt beautifully. Feel free to blend cheddar with these for a unique twist on the Cheesy Scalloped Potatoes with Thyme Recipe.
