Step‑by‑Step Instructions for Joanna Gaines’ Creamy Gruyere Potato Casserole
Step 1: Prepare Potatoes
Begin by preheating your oven to 375°F (190°C) to ensure it’s hot and ready for baking. While it heats, wash and slice the Yukon Gold potatoes into thin rounds, approximately 1/8 inch thick. You can leave the skin on for added texture. Arrange the sliced potatoes in a large mixing bowl, ready to absorb the creamy goodness of the casserole.
Step 2: Make Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of unsalted butter. Once melted, whisk in ¼ cup of all-purpose flour to create a roux and cook for 1-2 minutes until light golden. Gradually pour in 2 cups of half-and-half, constantly stirring until the mixture thickens and bubbles—about 5-7 minutes. This creamy base forms the heart of your potato casserole.
Step 3: Add Flavors
Once the sauce is thickened, remove the pan from heat and stir in 2 cloves of minced garlic, 1 teaspoon of chopped fresh thyme, 1 teaspoon of kosher salt, and ½ teaspoon of ground black pepper. Mix well until all flavors are combined. The aromatic blend will elevate your creamy potato casserole and infuse it with rich, savory depth.
Step 4: Layer Ingredients
In a greased 9×13 inch baking dish, create a layer of the sliced potatoes, ensuring they are evenly arranged. Drizzle half of the creamy sauce over the potatoes, followed by a generous sprinkle of 1 cup of shredded Gruyere cheese. Repeat this layering process with the remaining potatoes, sauce, and cheese, finishing with a final layer of cheese on top for that delightful golden crust.
Step 5: Bake
Place the assembled potato casserole in the preheated oven and bake for 45-60 minutes. You’ll know it’s ready when the top is golden brown and the casserole is bubbling around the edges. For the best results, keep an eye on it during the last 10 minutes to ensure the cheese doesn’t burn but achieves a beautiful, crispy texture.
Step 6: Serve
After baking, remove the casserole from the oven and allow it to cool for about 10 minutes. This resting period helps the sauce set and makes serving easier. Scoop out portions of the creamy Gruyere potato casserole, providing that satisfying warm and bubbly goodness for your family and friends to enjoy!

How to Store and Freeze Potato Casserole
Fridge: Keep any leftover potato casserole in an airtight container; it will stay fresh for up to 3 days.

Reheating: When ready to enjoy, thaw overnight in the fridge. Reheat in the oven at 350°F (175°C) for about 30-45 minutes or until heated through.
Serving Tip: To maintain the creamy texture of the potato casserole, cover with foil during reheating, then remove the foil in the last 10 minutes to crisp up the top.

Expert Tips for Potato Casserole
- Slice Evenly: Ensure you slice the Yukon Gold potatoes uniformly to guarantee even cooking throughout the casserole; a mandoline can help achieve perfect thickness.
- Adjust Baking Time: Keep an eye on the cooking time based on the depth of your baking dish; deeper casseroles may need extra time in the oven for a perfectly cooked potato casserole.
- Let It Rest: Allow the casserole to sit for 10 minutes after baking; this helps the creamy layers set properly, making it easier to serve.
- Cheese Choice: While Gruyere is delicious, feel free to experiment with other cheeses, but avoid using pre-shredded cheese for a creamier texture.
- Add Flavor Boosters: Don’t hesitate to toss in extras like cooked bacon, ham, or fresh veggies for added richness and nutrition in your potato casserole.

Joanna Gaines’ Creamy Gruyere Potato Casserole Recipe FAQs
What kind of potatoes work best for this casserole?
The star of this dish is definitely the Yukon Gold potatoes! Their creamy texture and buttery flavor make them perfect for baking. The skins can be left on for added character, but ensure they are freshly washed to retain their goodness.
How should I store leftover potato casserole?
Absolutely! To keep your leftover potato casserole fresh, store it in an airtight container in the fridge for up to 3 days. When ready to reheat, pop it back in the oven to rejuvenate its creamy texture instead of using a microwave, which can make it a bit soggy.
Can I freeze the potato casserole?
Yes, you can! To freeze your potato casserole, first allow it to cool completely. Wrap it tightly in plastic wrap, then cover with aluminum foil for added protection. You can freeze it for up to 2 months. When you’re ready to enjoy it, just thaw it overnight in the fridge and reheat as directed.
What if my casserole is too watery after baking?
If your casserole turns out watery, it might be due to excess moisture in the potatoes. To troubleshoot this, I recommend slicing the potatoes thinner next time, around 1/8 inch, to ensure better cooking and absorption of the creamy sauce. Additionally, allowing the casserole to rest for 10 minutes after baking can help it set up nicely.
Is this potato casserole suitable for dietary restrictions?
Yes, you can definitely make adjustments! For those with gluten sensitivities, substitute the all-purpose flour for cornstarch. Also, if you’re lactose intolerant, try using lactose-free dairy products like lactose-free half-and-half and cheese. Just be sure to check the specifics based on individual dietary needs.
How can I customize the flavors in this casserole?
The more, the merrier! You can swap Gruyere for sharp cheddar for a punchier flavor or even add cooked bacon or diced ham for a savory kick. Fresh veggies like spinach or kale not only add nutrition but also bring vibrant colors to this delicious dish. Mix and match based on what you have on hand, and trust your taste buds!
