When you think of indulgent comfort food, potatoes often top the list. Today, I’m sharing a recipe that elevates the humble spud into a rich, creamy, and utterly satisfying dish: Potatoes Romanoff.

Let’s dive into the delightful world of Potatoes Romanoff and discover why this dish deserves a spot on your dinner table.

What Are Potatoes Romanoff?

Potatoes Romanoff is a classic American dish that dates back to the mid-20th century. It is believed to have been popularized by Las Vegas’s iconic Strip House steakhouse. 

It’s essentially a creamy, cheesy, and slightly tangy potato casserole made with shredded baked potatoes, sharp Cheddar cheese, and a dollop of sour cream. 

The result? A rich, fluffy, and flavorful side dish that pairs perfectly with steaks, roasts, or even as a stand-alone vegetarian main.

Ingredients You’ll Need

Russet Potatoes – I’ve never tried this recipe with a yukon gold potato, but the starch content of the Idaho potatoes makes a great casserole. I need to try this recipe withe frozen hashbrowns, it seems like it would work!

Large russet potatoes are the ones we (in America!) use for a Baked Potato Bar.

Onion – I used a yellow onion because I had it on hand, but a raw shallot would be sensational in this delicious recipe.

Sour Cream – tangy sour cream is one of my favorite ingredients to use in a casserole! (Or any dish!) It’s one of those basic ingredients that makes a huge difference when you use it. 

Shredded Cheese – sharp white cheddar cheese is traditional, but feel free to use a cheese you have on hand. 

You’ll also need pepper (black pepper or white pepper), salt,  and some chives or green onions for garnish if you want to.

How to Make a Potatoes Romanoff Recipe

First, Bake the Potatoes

Start by preheating your oven to 400°F (200°C). Scrub the potatoes clean and prick them with a fork several times to allow steam to escape during baking. Place the potatoes directly on the oven rack and bake for about 1 hour or until they are tender when pierced with a fork. Once baked, let the potatoes cool completely. This step can be done a day in advance to save time.

Next, Prep the Potatoes

Using a box grater, shred the potatoes into a large bowl. Shredding the potatoes while they’re cold helps maintain a fluffy texture and prevents them from becoming mushy.

I left the skin on the potatoes because it doesn’t bother me. If it bothers you, peel your potatoes before grating! 

As you grate the potatoes, you’ll end up with the potato skin in your hand but the white inside all grated. You can toss the skin or put it in your air fryer for a few minutes and have crispy potato skins!

Then, Mix the Ingredients

In the same bowl, add the finely chopped onion, sour cream, grated Cheddar cheese, melted butter, salt, and black pepper. Gently fold the ingredients together until well combined. Be careful not to overmix, as you want to keep the potatoes light and airy.

Finally, Assemble and Bake

Transfer the potato mixture into a prepared baking dish, spreading it out evenly. 

Sprinkle a bit more Cheddar cheese on top for a golden, cheesy crust. I’ve experimented with parmesan cheese on top, which gives a gorgeous golden brown color to the top of the casserole.

Bake in the preheated oven at 350°F (175°C) for 30-35 minutes or until the top is bubbly and lightly browned.

Garnish and Serve

Remove the dish from the oven and let it sit for a few minutes to cool slightly. Sprinkle the top with freshly chopped chives or green onions for a burst of color and a hint of freshness. 

Serve your Potatoes Romanoff hot, straight from the baking dish, and watch as your family or guests dive in with delight.

This is one of those recipes that is great baked-in individual ramekins! Making steakhouse at home extra special with individual servings!

Tips for Success

Choose the Right Potatoes: Russet potatoes are ideal for this recipe because of their starchy texture, which helps create a fluffy and creamy dish.

Pre-Bake and Cool: Baking the potatoes in advance and allowing them to cool completely ensures the perfect texture when shredded. If you’re having baked potato night, go ahead and bake a few extra. Use the leftover baked potatoes for this potato Romanoff casserole. 

Use Sharp Cheddar: The bold flavor of sharp Cheddar cheese cuts through the richness of the potatoes and sour cream, adding depth to the dish

Don’t Overmix: Gently folding the ingredients preserves the texture of the shredded potatoes and prevents them from becoming gummy.

Customize Your Dish: Feel free to add extras like crispy bacon bits, sautéed mushrooms, or even a touch of garlic powder for an added twist.

What to Serve with this Cheesy Potato Casserole

Potatoes Romanoff is incredibly versatile and pairs well with a variety of dishes. Of all the cheesy potato casseroles, this is the one I don’t hear of often. You hear of funeral potatoes or hashbrowns casserole, but this is such a classic side dish.

Here are a few suggestions to complete your meal:

Grilled or Roasted Meats: Serve alongside a juicy steak, roast chicken, or pork tenderloin for a hearty and satisfying dinner.

For me, serving alongside a Beef Tenderloin for a holiday meal is wonderful. But, a nice filet mignon is my favorite steak for Potatoes romanov.

Fresh Salads: A crisp, green salad with a tangy vinaigrette balances the richness of the potatoes. It’s the perfect accompaniment to a simple recipe

Steamed or Roasted Vegetables: Lightly seasoned vegetables, such as asparagus, broccoli, or green beans, make a great complement.

For big holiday gatherings, this potato casserole is something you can make a couple of days ahead of time, and heat before you serve the meal. 

Potatoes Romanoff, or “Potatoes Romanov,” as some like to call it, is a dish that combines simplicity and luxury in every bite. 

Whether you’re hosting a special dinner or looking for a comforting side dish, this creamy, cheesy potato casserole is sure to impress. It will be a wonderful addition to any menu you serve your whole family!
