Rich, thick, and loaded with the kind of toppings that make a bowl feel like a meal, this copycat Chili’s baked potato soup has the same restaurant-style comfort people go back for again and again. The base stays velvety without turning gluey, the potatoes hold some texture, and the finish is exactly what you want: cheddar melting into the hot soup, a little tang from sour cream, and smoky bacon on top of every spoonful.
What makes this version work is the way the flour gets cooked in butter before any liquid goes in. That step takes the raw edge off the roux and gives the soup body without tasting pasty. Baked russet potatoes matter here too, because they bring that dry, fluffy potato texture you just can’t get from boiling them first. A little mashing once they’re in the pot gives the soup the best of both worlds — thick and hearty, with some chunks left behind.
Below, I’ll walk through the part that keeps the soup smooth, the ingredient swaps that still taste right, and the reheating trick that keeps the dairy from separating the next day.
The soup thickened up just like the restaurant version, and mashing some of the potatoes into it gave it that hearty texture without turning it into mashed potatoes. My husband went back for seconds before I even sat down.
Save this copycat Chili’s baked potato soup for the nights when you want that loaded, creamy restaurant bowl without leaving the house.
The Trick to a Soup That Tastes Like the Restaurant Version, Not Mashed Potatoes in Milk
The gap between a good baked potato soup and a great one usually comes down to texture control. If every potato is fully broken down, the soup turns heavy in the wrong way. If you leave them all in big cubes, it feels thin and disconnected. This version lands in the middle by mashing some of the potato flesh into the broth while leaving enough chunks to remind you it started with real baked potatoes.
The other place people go wrong is rushing the flour and milk base. That roux needs a couple of minutes in the pot before the liquids go in, and the soup needs enough time to thicken before the cheese and sour cream are added. If you bring dairy in too early or over high heat, it can turn grainy instead of smooth.
What Each Ingredient Is Actually Doing in This Bowl
- Russet potatoes — These are the right potatoes for a baked potato soup because they get fluffy and dry on the inside after baking. That texture breaks down into the broth better than waxy potatoes, which tend to stay too firm.
- Bacon — Use it in two places: folded into the soup and piled on top. The bits inside add smokiness to every bite, while the topping keeps the finish tasting like a loaded baked potato.
- Butter and flour — This is the roux that thickens the soup. Cook it until it smells a little nutty and looks pale gold; if it stays raw, the soup can taste pasty.
- Whole milk and chicken broth — The milk gives the soup body and the broth keeps it from tasting flat or overly rich. You can swap in 2% milk in a pinch, but the soup won’t be quite as plush.
- Cheddar and sour cream — Add both off the heat or over very low heat so the soup stays smooth. Sharp cheddar gives the strongest flavor here, and the sour cream brings the tang that makes this taste like the restaurant version.
Building the Base Without Breaking the Dairy
Start With the Roux
Melt the butter over medium heat, whisk in the flour, and cook it for 2 to 3 minutes until it looks slightly golden and smells cooked instead of floury. That short cook time is what keeps the soup from tasting raw. If you stop too early, the base can have a chalky edge that shows up even after the milk goes in.
Whisk in the Liquid Slowly
Pour in the milk and broth gradually while whisking. The mixture will look thin at first, then turn glossy as it warms and thickens. If you dump all the liquid in at once, the roux can clump before it has a chance to dissolve smoothly.
Work the Potatoes the Right Way
Fold in the chopped baked potato flesh once the base has thickened. Mash some of the pieces against the side of the pot, but leave plenty whole. That gives the soup its signature restaurant texture — thick enough to coat a spoon, with enough potato pieces to keep every bite interesting.
Finish Off the Heat
Stir in the cheddar and sour cream with the heat low enough that the soup barely simmers, not boils. High heat is what makes dairy grainy. The cheese should melt into the soup and disappear into the base; if you see stringy bits or oily separation, the pot was too hot.
Make It Lighter Without Losing the Loaded Potato Feel
Use 2% milk instead of whole milk and cut the cheddar back slightly. The soup will still thicken, but it won’t be quite as rich or velvety. Keep the sour cream, though — that tang is part of what makes the bowl taste complete.
Gluten-Free Version
Swap the all-purpose flour for a gluten-free 1:1 flour blend that includes xanthan gum. The texture comes out nearly the same if you cook the roux long enough, though you may need a minute or two more for full thickening.
Vegetarian Swap
Skip the bacon and use vegetable broth instead of chicken broth. The soup loses some smokiness, so add a pinch of smoked paprika or extra black pepper to bring back some depth.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days. It will thicken as it chills.
- Freezer: You can freeze it, but dairy-based soups may separate slightly when thawed. For the best texture, freeze before adding the sour cream and cheddar, then stir those in after reheating.
- Reheating: Warm it slowly over low heat with a splash of milk or broth. Fast reheating can make the dairy split and turn the texture grainy.

Method
- Melt the unsalted butter in a large pot over medium heat, then whisk in the all-purpose flour and cook for 2-3 minutes until golden, stirring to avoid browning too fast.
- Gradually whisk in the whole milk and chicken broth until smooth, then cook over medium heat for about 10 minutes, stirring constantly, until the mixture thickens to a creamy, spoon-coating consistency.
- Fold in the chopped baked potato flesh and mash some pieces into the soup so you get a mix of smooth creaminess and chunky bites.
- Stir in the shredded cheddar and sour cream until smooth, then season with salt, black pepper, and garlic powder, mixing well so the seasoning is evenly distributed.
- Fold in half of the crumbled bacon so the soup is layered with flavor throughout.
- Serve in bowls loaded with extra sour cream, shredded cheddar, the remaining bacon, and chives so each bowl has the full loaded presentation.
