Ingredients for copycat longhorn potato soup
Six ingredients make this restaurant-style potato soup taste just like Longhorn's famous version.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 2 whole | Diced into small pieces |
| Celery Stalks 🥬 | 4 whole | Diced small, not too fine |
| Carrots 🥕 | 3 whole | Diced into small cubes |
| Unsalted Butter 🧈 | ½ cup | Full-fat for best flavor |
| All-Purpose Flour 🌾 | ½ cup | For perfect roux |
| Beef Broth 💧 | 6 cups | Low-sodium preferred |
| Russet Potatoes 🥔 | 3 lb | Diced into 1-inch pieces |
| Shredded Sharp Cheddar Cheese 🧀 | 3 cups | Longhorn-style preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Dried Parsley 🌿 | 1 tsp | For garnish |
| Salt 🧂 | 2 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth |
| Smoked Paprika 🌶️ | ½ tsp | For that smoky touch |
The cheddar cheese is non-negotiable—Longhorn's signature sharp cheddar gives that iconic flavor. Grab 3 cups of freshly shredded (not pre-shredded) from the deli counter if you can, or Kraft Longhorn style from the store. The potatoes should be russet—they hold up better to simmering. For the beef broth, Store brand works fine, but Kirkland Signature or Annie's take it up a notch. The butter? Land O'Lakes or Plugrá—full-fat makes all the difference here. Don't skip the smoked paprika—it's what gives that subtle smoky depth you'd expect from a steakhouse.
No sharp cheddar? Pepper jack works in a pinch, but it changes the flavor profile. Running low on thyme? Dried oregano at half the amount gets you close. The garlic can be pre-minced, but freshly minced tastes exponentially better. For the roux, don't rush it—cook it until it's a deep golden brown, not white. The celery and carrots? Baby carrots and pre-cut celery from the store are perfect—no chopping required. If you want to stretch this further, add 1 cup of corn for a sweet contrast (like the restaurant version sometimes does).
This soup tastes even better the next day—make a double batch if you can. Store leftovers in the fridge for up to 5 days or freeze for 3 months. The cheese crust? Broil for 2-3 minutes at the end for that perfect crisp. For serving, I like to garnish with extra cheese and parsley—it makes it look restaurant-worthy. Reheat gently on the stove or microwave—just add a splash of broth or milk to loosen it up.
Why You'll Love This Recipe
- No-Fuss Soup Base: I swear by this roux trick—just butter, flour, and a splash of broth—it builds that creamy, velvety texture without heavy cream. Honestly, it’s the secret to that restaurant-quality mouthfeel, and it takes less time than boiling water for noodles.
- Savory Crunch Factor: That crispy edge on the potatoes? It’s all in the slow simmer and the way the carrots and celery caramelize just enough. Between us, the onions get sweet and golden—like someone’s been slow-cooking them all day (but we’re not telling).
- Game-Day Crowd Pleaser: This soup disappears at tailgates, potlucks, or even a lazy Sunday. I’ve served it in a slow cooker for 6 people and in a single pot for two—same great taste, zero stress. (Yes, even on a Tuesday night.)
- Budget-Friendly Leftovers: A pound of potatoes and a bag of carrots stretch this into three meals. I’ll be real: my freezer’s full of it, and reheating it just makes it richer. Plus, the flour-butter roux stretches like magic—no waste, all flavor.
Step-by-step instructions for Longhorn steakhouse potato soup
Here's how to recreate that iconic cheesy crust and smoky flavor in your own kitchen.
Sauté the Vegetable Base
Melt the 0.5 cup unsalted butter in a large Dutch oven over medium heat. Add the 2 whole diced yellow onions, 4 whole diced celery stalks, and 3 whole diced carrots, stirring frequently for 8-10 minutes until they soften and begin to caramelize. You'll know it's ready when the vegetables release their moisture and start to stick slightly to the pan.
Add the 4 minced garlic cloves and 0.5 teaspoon smoked paprika, cooking for another 30 seconds until fragrant. This step builds the flavor foundation—don't rush it. The paprika adds that signature smoky depth that makes this soup taste just like Longhorn's.
Create the Perfect Roux
Sprinkle the 0.5 cup all-purpose flour over the vegetable mixture and stir vigorously for 2-3 minutes until it forms a smooth, golden roux. This should be the color of peanut butter—lighter than chocolate but darker than vanilla. If it starts to darken too quickly, reduce the heat slightly to prevent burning.
Gradually whisk in the 6 cups beef broth, one ladle at a time, ensuring no lumps form. Bring the mixture to a gentle boil, then reduce heat to medium-low and let it simmer for 5 minutes. This step thickens the soup and removes any raw flour taste, creating a velvety base.
Add Potatoes and Seasonings
Add the 3 lb diced russet potatoes to the pot, along with the 2 teaspoons salt, 0.5 teaspoon black pepper, 1 teaspoon dried thyme, and 1 teaspoon dried parsley. Stir gently to combine, then increase heat to medium-high and bring to a boil. Once boiling, reduce heat to medium-low and let it simmer uncovered for 20-25 minutes, stirring occasionally, until the potatoes are fork-tender.
Here's the thing—don't rush this step. The potatoes need time to break down completely, creating that signature creamy texture. You'll know they're done when they easily mash with a fork, but still hold their shape slightly.
Finish with Cream and Cheese
Reduce heat to low and stir in the 1 cup heavy cream and 3 cups shredded sharp cheddar cheese, letting the cheese melt completely into the soup. Taste and adjust seasoning if needed—this is where you can really make it your own. The cheese should be fully melted and create that signature creamy, cheesy texture that makes this soup so addictive.
For that restaurant-quality cheesy crust, preheat your broiler. Transfer the soup to an oven-safe dish, sprinkle an additional ½ cup shredded cheddar cheese on top, and broil for 2-3 minutes until golden brown and bubbly. Watch it closely—it burns quickly!
Serve Warm with Crusty Bread
Let the soup sit for 5 minutes off the heat before serving. This resting time allows the flavors to meld together perfectly. The top should be golden and crispy, while the soup underneath remains creamy and rich. Serve immediately with warm crusty bread to soak up every last drop of that cheesy goodness.
This soup tastes even better the next day, so make extra if you can. The flavors deepen as it sits, making each spoonful even more comforting. Trust me, once you try this copycat version, you'll never want to go back to store-bought!
Pro Tips For Making Copycat Longhorn Potato Soup
- SWEEAT THE VEGETABLES: I learned this the hard way—rushing the onion, celery, and carrot cook-down leads to a raw, bitter flavor that ruins the whole dish. Simmer them in the butter for 10-12 minutes on medium-low heat until they’re soft enough to mash between your fingers. (Yes, even if they look mushy—this is where the depth of flavor hides.)
- USE FLOUR LIKE GLUE: The roux is non-negotiable here, but don’t just toss in the flour and stir. Cook it in the butter for 3-4 minutes until it’s a pale golden color—any darker, and you’ll taste burnt notes. Then, whisk in the broth gradually while stirring constantly. (This isn’t the prettiest method, but it’s the tastiest.)
- SKIP THE BOILING POTATOES: I used to boil the potatoes whole first, then mash them in, but that makes the soup watery. Instead, parboil them for 8-10 minutes (until fork-tender but still holding shape), then drain and mash them directly into the soup. This keeps the texture thick and creamy without adding extra liquid.
- SALT THE BUTTER FIRST: Unsalted butter is your friend, but only if you salt it before melting it. Toss in ½ teaspoon of salt per 4 tablespoons of butter while it’s warming—this balances the flavor from the start. (Trust me, your future self will notice the difference when you skip this.)
Serving suggestions for this dish
Crusty Bread Pairings
Nothing enhances this creamy potato soup like a warm, crusty bread to soak up every last drop. I recommend sourdough or baguette slices—their sturdy texture holds up beautifully against the rich, cheesy soup.
For extra indulgence, try garlic bread made with Butterball garlic herb butter—the buttery, garlicky flavor complements the smoky depth of the soup perfectly. 🥖
If you want to get fancy, toast brioche rolls and serve them on the side. Their slightly sweet, buttery flavor contrasts wonderfully with the sharp cheddar. For a gluten-free option, schar bread (made with almond flour) works surprisingly well and adds a nutty dimension to the meal.
Cheesy Additions
The original recipe already includes plenty of cheddar, but you can take it to the next level with extra toppings.
Sprinkle crumbled bacon on top for a smoky, salty crunch—about ¼ cup adds just the right amount of flavor. Green onions or chives provide a fresh, bright contrast to the richness.
I like to add 1-2 tablespoons of sour cream when serving to balance the heat if you prefer a milder version. 🧀
For a spicy kick, add 1 teaspoon of hot sauce or a dash of Cayenne pepper to individual bowls. If you love texture, try crushed tortilla chips on top—they add a satisfying crunch that pairs perfectly with the creamy soup.
Just be sure to let guests add their own toppings after serving to keep the crust crispy!
Side Dish Ideas
A simple mixed green salad with a light vinaigrette balances the richness of the soup beautifully. Toss 4 cups baby spinach with 2 tablespoons olive oil, 1 tablespoon apple cider vinegar, and a pinch of salt and pepper.
Add ½ cup diced cucumbers and ¼ cup crumbled feta for extra brightness. 🥗
For a heartier side, serve crispy roasted Brussels sprouts with a sprinkle of balsamic glaze. Toss 1 lb Brussels sprouts with 2 tablespoons olive oil, ½ teaspoon smoked paprika, and ½ teaspoon salt, then roast at 425°F for 20-25 minutes until caramelized.
The smoky, slightly sweet flavor pairs wonderfully with the soup.
Beverage Pairings
A cold dark beer like Guinness or Samuel Adams Black Lager cuts through the richness of the soup beautifully. The roasted malt flavors complement the smoky depth, while the carbonation cleanses your palate.
For a non-alcoholic option, sparkling apple cider with a splash of ginger beer adds a refreshing contrast. 🍺
If you prefer wine, a bold red like Cabernet Sauvignon or Merlot stands up to the cheesy, hearty flavors. For a lighter option, a crisp Chardonnay with a touch of oak balances the creaminess without overpowering the dish.
I like to serve a small glass of bourbon on the side for sipping—its caramel notes echo the soup’s smoky undertones.
Presentation Tips
Serve the soup in deep, rustic bowls—they make the crispy cheese crust look even more impressive. Ladle the soup carefully to preserve that golden top layer. Garnish with extra shredded cheddar, fresh parsley, and a drizzle of hot sauce for a restaurant-worthy finish. 🍽️
For a fun twist, serve the soup in individual cast-iron skillets and let guests broil their own cheese crust at the table. This interactive approach adds excitement, especially for gatherings.
If you're serving a crowd, use a slow cooker to keep the soup warm and the crust crispy—just transfer it to individual bowls before serving.

Frequently asked questions
Can I make this potato soup without a Dutch oven?
A Dutch oven is ideal for even cooking, but you can use a large, heavy pot or even a slow cooker. For the slow cooker method, combine all ingredients except the cheese crust, cook on low for 4-5 hours, then broil the cheese topping separately. A heavy pot works too—just stir occasionally to prevent sticking.
Why does my cheese crust keep getting soggy?
Soggy cheese happens when moisture seeps through before broiling. Fix this by broiling the soup for 2-3 minutes right before serving—never ahead of time. For extra insurance, sprinkle the cheese on top just before broiling and watch closely to avoid burning. The crust needs that final crispy moment!
Can I substitute the sharp cheddar with another cheese?
Sharp cheddar is key for that iconic Longhorn flavor, but you can use Pepper Jack for a spicier kick or Monterey Jack for a milder taste. Avoid pre-shredded cheese—the anti-caking agents prevent proper melting. For a smoky twist, try smoked Gouda instead.
How do I make this soup creamier without heavy cream?
Swap the heavy cream for ½ cup sour cream or Greek yogurt for tangy richness, or use ½ cup evaporated milk> for a lighter option. For extra creaminess, mash some of the cooked potatoes into the soup before adding the cheese. The roux alone provides a creamy base, but these tweaks take it to the next level!
Can I freeze this soup for later?
Yes! Freeze the soup (without the cheese crust) in airtight containers for up to 3 months. Thaw overnight in the fridge, then reheat on the stove with a splash of broth or milk to restore creaminess. Add fresh cheese topping when reheating—it won’t crisp up from frozen.
