Omaha Steaks Potatoes au Gratin Recipe

Omaha Steaks is known for delivering quality steaks straight to the door. They have a large menu, and one of the most popular sides is their Potatoes au Gratin. That creamy cheese sauce and crispy top have always been my favorite. After too many orders, I decided to make it myself. This copycat Omaha Steaks Potatoes au Gratin Recipe comes surprisingly close to the original.

No need to wait for a delivery when you can make it in your own oven. Just follow the recipe, and you will have that same restaurant-style flavor at home.

What Is the Difference Between Potato Gratin and Scalloped Potatoes

Both dishes are made by layering sliced potatoes, but they have some differences. Potato gratin uses cheese and a rich sauce, while scalloped potatoes rely on a lighter cream base.

1. Cheese Content: Potato gratin almost always includes cheese layered between the potatoes, giving it a rich, savory taste. Scalloped potatoes usually skip cheese entirely, keeping the dish simpler with just cream and seasoning.

2. Sauce Style: Gratin recipes often use a cheese sauce made with butter, flour, and milk for a thick texture. Scalloped potatoes typically use plain cream or milk, giving a lighter, thinner sauce overall.

3. Texture Difference: Potato gratin turns out thicker and creamier because of the cheese and roux. Scalloped potatoes have a softer, more delicate texture since the sauce stays thin and light throughout baking.

4. Topping Difference: Gratin dishes often get a golden, bubbly cheese top from broiling at the end. Scalloped potatoes rarely have a cheese topping, so the top layer stays soft and pale.

What Potatoes Are Best for Au Gratin Potatoes

The right potato helps control the final texture. I like Russet potatoes for this recipe.

Russet Potatoes Russet: potatoes work best for au gratin because they have a starchy texture that thickens the sauce naturally. Their firm structure holds up well during a long bake, and they stay creamy inside without falling apart.

Yukon Gold Potatoes: Yukon Gold potatoes offer a buttery flavor and creamy texture, making them a solid backup choice. They hold together during baking but soften a bit more than Russets, giving a slightly different bite.

Avoid Waxy Potatoes: Waxy potatoes, like red potatoes, do not work as well for this dish. They stay too firm and do not soak up the cheese sauce, leaving the layers less flavorful and creamy overall.

Omaha Steaks Potatoes au Gratin Ingredients

These simple ingredients create the creamy potato layers and cheesy sauce. Each amount is set for this recipe, with easy swaps listed below when a substitute works well.

• Russet Potatoes (2 pounds): Thinly sliced Russet potatoes create tender layers and help the sauce thicken naturally. Yukon Gold potatoes can replace them using the same amount.

• Butter (1/4 cup): Butter gives the sauce a smooth base and also helps grease the baking dish. Divide the 1/4 cup between the roux and the dish. Salted or unsalted butter works, though extra salt should be adjusted when using salted butter.

• All-Purpose Flour (1/4 cup): Flour combines with melted butter to form the roux that thickens the milk. Use 1/4 cup for the sauce. A gluten-free all-purpose flour blend can replace regular flour in the same amount.

• Milk (2 cups): Milk creates the creamy base for the cheddar sauce. Whole milk gives the smoothest result, though 2% milk can also work. For a fuller sauce, use 2 cups of half-and-half instead of milk.

• Sharp White Cheddar Cheese (2 cups): Sharp white cheddar gives the potatoes their creamy cheese flavor while keeping the sauce pale. Mild white cheddar can replace it using the same 2-cup amount.

• Onion (1/2 cup): Thinly sliced onion adds gentle savory flavor and softens during baking. Yellow onion works well, but white onion can replace it using the same 1/2-cup amount.

• Salt (To Taste): Salt brings out the potato, cheese, and onion flavors. Start with a small amount between the potato layers and add more after tasting the sauce. The amount can vary based on the cheese and butter used.

• Black Pepper (To Taste): Black pepper adds mild warmth and balances the creamy sauce. Freshly ground pepper works well, but regular ground black pepper can also be used. Sprinkle a small amount between the potato layers.

• Fresh Chives (1 to 2 Tablespoons): Chopped fresh chives add a fresh finish just before serving. Use 1 to 2 tablespoons based on preference. Thinly sliced green onion can replace the chives in the same amount.

Making Omaha Steaks Potatoes au Gratin at Home

Follow these simple steps, and you’ll end up with tender potato layers coated in creamy cheddar sauce and finished with a golden, bubbly top.

1. Heat the Oven

Set the oven to 400°F and let it heat fully. This temperature helps the potatoes cook until tender while the cheese sauce becomes hot and bubbly.

2. Slice the Russet Potatoes

Thinly slice 2 pounds of Russet potatoes into ⅛-inch-thick slices. A mandoline makes it easier to create thin, even slices, but a sharp knife works well too.

Try to keep the slices similar in thickness so the potatoes cook evenly and become tender throughout.

3. Grease the Baking Dish

Use part of the 1/4 cup butter to coat the bottom and sides of a 9 × 13-inch baking dish. A good coating helps the potato layers release more easily after baking.

4. Make the Cheddar Cheese Sauce

Melt the remaining butter in a saucepan over medium heat. Stir in 1/4 cup flour and whisk until smooth. Slowly pour in 2 cups milk, whisking as you add it.

Bring the sauce to a gentle boil and keep whisking until it thickens enough to coat a spoon. Lower the heat, then stir in 2 cups shredded sharp white cheddar until fully melted and smooth.

5. Layer the Potatoes, Onion, and Cheese Sauce

Place a layer of sliced potatoes in the prepared dish. Season lightly with salt and black pepper, then add some of the sliced onion.

Spoon some of the cheddar cheese sauce over the potatoes. Repeat the layers with the remaining potatoes, onion, seasoning, and cheese sauce, finishing with the remaining cheese sauce on top.

6. Cover and Bake

Cover the dish with foil and place it in the 400°F oven. Bake for about 1 hour, or until the potatoes are tender and the sauce is bubbling well around the edges.

Remove the foil once the potatoes are tender. Turn on the broiler and let the top brown for a short time. Keep a close eye on it because the cheddar can brown quickly.

7. Let the Potatoes au Gratin Rest

Remove the dish from the oven and let it rest for about 10 minutes. This gives the sauce time to thicken slightly and settle between the potato slices.

8. Finish with Chives and Serve the Potatoes au Gratin

Sprinkle chopped fresh chives over the top just before serving. The fresh chives add a simple finishing touch to the Omaha Steaks Potatoes au Gratin.

Chef Tips I Follow for a Creamy Center and Crispy Top

While making these Omaha Steaks Potatoes au Gratin, I found a few small but helpful notes that made a big difference. So, while making your own recipe, pay attention to these small details for the best flavor and texture.

1. Slice Potatoes Evenly – Even potato slices cook at the same rate, helping the center become tender and creamy. A mandoline makes it easier to keep each slice thin and even.

2. Season Every Layer – Add a little salt and pepper between the potato layers rather than putting it all on top. This gives each bite a more balanced flavor.

3. Let It Rest – Let the baked potatoes rest for about 10 minutes before serving. This gives the sauce time to thicken slightly and helps the layers hold together.

4. Watch the Broiler Closely – The broiler can brown the cheddar very fast. Stay close during this step and remove the dish once the top has a nicely browned finish.

Make Omaha Steaks Potatoes au Gratin Ahead of Time

These Omaha Steaks Potatoes au Gratin work well for planning ahead. Assemble the potato, onion, seasoning, and cheese sauce layers in the baking dish as directed in the recipe.

Cover the dish tightly and refrigerate for up to 1 day before baking. Take the dish out about 30 minutes before baking so it can lose some of its chill.

The baking time may be slightly longer when starting from cold, so check the potatoes with a fork before removing the foil. This process saves time while keeping the center creamy and the cheese top golden.

My Favorite Ways to Serve These Potatoes au Gratin

These potatoes work well beside a simple main dish. I especially like serving them with steak because the creamy cheddar sauce pairs well with the savory meat.

For an easy meal, serve a spoonful of potatoes with grilled steak and a crisp green salad. Roasted chicken, baked chicken breast, pork chops, or roasted vegetables also work nicely.

Refrigerating and Freezing Tips

Refrigerating Tips –

Place cooled leftovers in an airtight container and refrigerate within two hours. They keep well for about 3 to 4 days. Store portions separately for easier reheating.

Freeze Options –

1. Freeze Before Baking – For the best texture, freezing the potatoes after baking is preferable. The assembled unbaked dish can still be frozen for up to 2 months, but the potatoes may become slightly softer after thawing.

Wrap the dish tightly before freezing, then thaw it overnight in the refrigerator before baking as directed. Add a little extra baking time as needed until the potatoes are tender.

2. Freezing After Baking – Cool the baked dish completely, then wrap portions tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Reheating Process for Potatoes au Gratin

• Oven – The oven gives the best texture and most even reheating. Cover the potatoes loosely with foil and heat at 350°F until hot in the center. Remove the foil near the end.

• Air Fryer – The air fryer works well for individual portions. Place a serving in an oven-safe dish and heat at about 325°F until warmed through. Watch the top so the cheese does not brown too much.

• Microwave – Place a portion in a microwave-safe dish and cover it loosely. Heat at medium power in short intervals, checking the center between rounds. Continue until heated through.

FAQs About Omaha Steaks Potatoes au Gratin Recipe

I’ve included these common questions to cover the small details that can come up while making this recipe. Hope these answers help clear up any confusion before you start cooking.

1. Why did my cheese sauce become lumpy?

Lumps can form when the milk is added too quickly or the flour and butter are not whisked well. Add the milk slowly while whisking constantly. Keep the heat moderate and continue whisking until the sauce becomes smooth and thick.

2. Can I slice the potatoes with a knife?

Yes. A mandoline is helpful, but it is not required. Use a sharp knife and aim for thin, similar-sized slices. Consistent slices help the potatoes cook at the same rate and give the finished dish an even texture.

3. Can leftovers be reheated more than once?

Reheating leftovers once is best for food safety and texture. Reheating multiple times can dry out the sauce and affect the overall creaminess of the dish.

4. Is it necessary to peel the potatoes first?

Peeling is optional. Leaving the skin on adds texture and a rustic look, while peeling creates a smoother, softer bite throughout the finished dish.

5. Can I add breadcrumbs on top?

Mix breadcrumbs with a little melted butter and sprinkle on top. It adds extra crunch. Add them during the last 10 minutes of baking so they don’t burn.
