Longhorn Steakhouse has one of my all-time favorite baked potato soup recipes. It’s unique because the soup is smooth, yet it hits you with amazing chunks of (not mushy) potatoes – combined with all sorts of other delicious flavors.

It took us a while to figure out how to make the base for this soup, and as we tasted it over and over again, it became clear that it was more of a cheddar-based soup than a potato soup. We felt that adding some potato flakes would add some extra potato flavor, but we really wanted to nail the cheddar flavor of it—and nailed it we did.

This soup is a little more time-intensive than some soups, but let me tell you – it is 100% worth it! If you’re a fan of Longhorn’s baked potato soup, I think you’ll love this version!

Ingredients

  • 1/4 cup salted butter
  • 1/4 cup all-purpose flour
  • 3 cups chicken broth
  • 3 cups milk
  • 16 ounces mild shredded cheddar cheese
  • 1/2 cup instant pot flakes
  • 2 large russet potatoes, diced and peeled
  • Salt
  • Pepper
  • Bacon Bits (You can make your own, but if you use store-bought, crisp them up on the stovetop – trust us, it makes a huge difference!)
  • Extra Cheddar (for topping)
  • Green Onions, diced

Instructions

  1. Over medium-high heat, melt butter in a 3-quart saucepan.
  2. Stir in flour and cook until flour has blended with butter.
  3. Add chicken broth and stir constantly until mixture starts to thicken.
  4. Add in milk and heat until it starts to simmer, stirring the whole time.
  5. Stir in shredded cheese until smooth.
  6. Add in potato flakes.
  7. Add lots of salt and pepper to taste—it really depends on taste, but I used 2 teaspoons of salt and 2 teaspoons of pepper. Start with a little and go up as you need it!
  8. Use an immersion blender to blend until smooth, or pour in batches into a blender.
  9. At this point, bring your soup to a light boil and add in your diced potatoes.
  10. Stir constantly, but allow the potatoes to cook until they are al dente. Keep stirring so the soup doesn’t stick to the bottom of the pot.
  11. Alternatively, boil the diced potatoes in a separate pot until al dente and add to soup right before serving.
  12. Serve soup immediately with cheddar cheese, bacon bits, and green onions.

Recipes Tips and Suggestions:

  • This soup really shouldn’t be frozen. Because potatoes dry out, they absorb moisture from the soup, leaving it extremely thick. Once defrosted, it can take on a grainy texture, which is not pleasant to eat.
  • This soup can be stored in the fridge for several days after you make it. Just store it in an airtight container. It is best when reheated on the stovetop over low heat—you may need to add some extra broth if it’s too thick.
  • This soup can be served as a main dish alongside a crusty piece of Longhorn Steakhouse bread or a fantastic side dish with just about any meat. Add a delicious side salad to round out the dish!

Variations and Substitutions:

  • Use a different blend of cheese for a different flavor profile
  • Add diced ham instead of bacon
  • You can use other types of potatoes – we just find that russets seem to work the best
  • Use a low fat milk to cut down on extra fat

  1. When do I add the potato flakes? I missed that part and left them out, but it was still wonderful! I just want to get it right next time I make some!

    1. So sorry! It is right after the cheese – the recipe has been updated to reflect this. So glad you enjoyed it!

  2. Just cooked this. I could not find potato flakes so I used dehydrated potatoes. Turned out great! I used too much but thined iut nicely with milk and a touch of water. I also used light cream for the milk. You nailed this recepie! Thank you!

  3. The only thing I would change is the amount of black pepper. I thought 2 tsp was too much. But other than that it was really good. But a little labor intensive for a weeknight meal, at least for me.
