Atlanta Bread Company Wisconsin Cheese Soup Recipe: Velvety Fondue-Style Richness

This Atlanta Bread Company Wisconsin cheese soup recipe delivers the same velvety fondue-style richness you crave, with a perfect balance of sharp cheddar and buttery bread. The secret lies in a slow-simmered roux that creates a silky texture without lumps, while toasted bread cubes add hearty texture.

I developed this recipe after years of perfecting the technique—every spoonful is creamy, cheesy, and deeply satisfying.

The foundation of this soup is a classic French-style roux cooked to a golden brown, which forms the base for a rich, velvety sauce. Wisconsin sharp cheddar melts into this roux, creating a flavorful, creamy foundation that's the heart of the soup.

The addition of toasted bread cubes adds a satisfying crunch and soaks up the cheese sauce beautifully.

What makes this recipe special is its balance of simplicity and depth. The slow simmer allows the flavors to meld together, resulting in a soup that's both comforting and elegant.

Each bite delivers a harmonious blend of sharp cheddar, creamy sauce, and toasted bread, making it perfect for chilly evenings or as a hearty appetizer.

This soup is designed to impress without being overly complicated. It's ideal for feeding a crowd or enjoying a cozy meal at home. The technique is straightforward, and the ingredients are simple, yet the result is restaurant-quality.

Let's get started on creating this velvety Wisconsin cheese soup that will become a family favorite.

Ingredients for atlanta bread company wisconsin cheese soup

Sixteen ingredients transform into velvety Wisconsin cheese soup with restaurant-quality depth.

The cheddar is non-negotiable—Wisconsin sharp delivers that signature tang. Local grocers or specialty cheese shops carry the best blocks, but a high-quality pre-grated works in a pinch. For the roux, European-style butter (like Plugrá) creates a richer flavor than American brands. The sourdough bread should be day-old—fresh bread gets soggy. Toast the cubes until golden before adding to the soup for maximum texture contrast. If you can't find sourdough, baguette or French bread works just as well, cut into similar-sized cubes.

No sharp cheddar? Gruyère or Emmental melts beautifully and adds nutty depth. Out of chicken broth? Vegetable broth with a splash of white wine keeps the flavor profile intact. The Dijon mustard adds subtle complexity—if you're avoiding it, a pinch of lemon zest gives a similar bright note. Fresh thyme is ideal, but dried works at one-third the amount. For the roux, don't rush the cooking—this is where the magic happens. Cook it low and slow until it reaches a deep golden brown, about 15-20 minutes. The bread cubes should be toasted until they're crisp at the edges but still hold their shape when pressed.

This soup tastes even better the next day as flavors meld. Store in an airtight container for up to 5 days in the fridge. For freezing, portion into single-serving containers—it reheats beautifully. The roux base can be made ahead and stored in the fridge for up to 3 days before adding the remaining ingredients. To reheat, warm on the stove over medium-low heat, stirring frequently to prevent lumps. The bread cubes will soften slightly but maintain their satisfying bite—add fresh toasted cubes on top when serving for that restaurant-quality crunch.

Step-by-step instructions for atlanta bread company Wisconsin cheese soup

This method delivers the signature velvety texture and rich Wisconsin cheddar flavor that makes this soup legendary.

In a heavy-bottomed pot over medium heat, melt the 0.75 cup unsalted butter until completely liquid. Add the 0.75 cup all-purpose flour all at once and whisk vigorously for 2-3 minutes until the mixture turns a rich, golden brown color. This is your roux foundation—don't rush this step, as proper browning develops deep flavor and helps thicken the soup.

Watch closely as the roux cooks. It should smell nutty and toasty before moving to the next step. If it darkens too quickly, reduce the heat slightly to prevent burning. The perfect roux is the secret to that signature smooth, velvety texture that sets this soup apart from ordinary cheese soups.

Immediately pour in the 4 cups chicken broth and whisk continuously for 1-2 minutes until the mixture is completely smooth. Add the 1 medium yellow onion and 4 cloves garlic cloves, stirring to incorporate. Bring the mixture to a gentle simmer over medium-low heat and cook for 8-10 minutes until the onion softens and the garlic becomes fragrant.

This is where the flavor foundation develops. You'll notice the mixture will thicken slightly as it simmers. Here's the thing—don't let it boil vigorously or the roux will break and create lumps. Keep the heat low enough to maintain a gentle simmer, and stir occasionally to prevent sticking at the bottom of the pot.

Reduce the heat to low and gradually whisk in the 3 cups whole milk and 2 cups Wisconsin sharp cheddar cheese in three additions. Start with half the milk and cheese, whisking until smooth before adding the remaining amounts. This gradual approach prevents curdling and ensures a silky texture. The soup should begin to thicken noticeably as the cheese melts.

Here's where it gets critical: keep the heat at a bare simmer. You want the cheese to melt completely but not cook too long, which can make the soup grainy. Stir constantly for 3-4 minutes until the cheese is fully incorporated and the mixture is smooth. If you see any lumps forming, immediately whisk them out—once they form, they're nearly impossible to fix.

Add the 1 tbsp Dijon mustard, 1 tsp dried thyme, 0.5 tsp black pepper, and 1.5 tsp kosher salt, stirring well to distribute. Then fold in the 1.5 cups sourdough bread cubes, letting them soak up some of the soup for 2-3 minutes before bringing everything to a gentle simmer again.

The sourdough bread adds wonderful texture contrast to the creamy soup. Let the soup simmer uncovered for another 5-7 minutes until it reaches your desired consistency. It should be thick enough to coat the back of a spoon but still flow smoothly. If it's too thick, you can thin it with a splash of warm milk or broth.

Remove the soup from heat and let it rest for 5 minutes to allow the flavors to meld. Drizzle with the 2 tbsp extra-virgin olive oil and stir gently to create a glossy finish. This final touch adds richness and helps prevent a skin from forming on top.

Serve immediately in warm bowls, garnished with additional cheese shavings if desired. The soup should be velvety smooth with a perfect balance of cheesy richness and savory depth. Each spoonful should deliver that signature Atlanta Bread Company experience—comforting, indulgent, and utterly satisfying.

Storing and reheating this recipe

Refrigerator Storage

Let your Wisconsin cheese soup cool to room temperature (about 30 minutes) before transferring to an airtight container. I use glass containers with tight-sealing lids to preserve freshness.

Store in the fridge for up to 5 days—the flavors actually deepen as the cheese continues to meld with the broth. The bread cubes will soften slightly but maintain their texture, while the roux base keeps its velvety consistency. 🥫

Freezer Prep Tips

For longer storage, portion the soup into single-serving containers or freezer bags. Leave 1 inch of headspace to prevent expansion cracks. I recommend using quart-sized containers for individual portions. Label with the date and freeze for up to 3 months.

The texture remains creamy when thawed properly, though the bread cubes may lose some crunch—just toast fresh cubes when reheating. ❄️

Stovetop Reheating

My preferred method is stovetop reheating over medium-low heat. Transfer the chilled soup to a pot and add 2-3 tablespoons of water or milk to prevent sticking. Heat gently, stirring frequently for 8-10 minutes until reaching 165°F.

The gradual warmth preserves the soup's silky texture. For best results, add fresh toasted bread cubes on top just before serving to restore that satisfying crunch. 🔥

Microwave Method

For quick reheating, transfer soup to a microwave-safe bowl and cover loosely with a microwave-safe lid. Heat on 50% power for 2-3 minutes, stirring halfway through. If the soup looks too thick, add 1 tablespoon of warm milk or broth and stir well.

Avoid overheating—this can make the cheese separate. I find this method works best for single servings when you're in a hurry. ✨

Reviving Texture

If your reheated soup seems too thick, thin it with warm milk or broth—about 1 tablespoon at a time—until it reaches your preferred consistency. For extra richness, stir in 1 teaspoon of butter while reheating.

The bread cubes will soften further, but their flavor remains intact. I often add a pinch of black pepper and dried thyme during reheating to refresh the seasoning. 💫

Make-Ahead Roux

You can prepare the roux base up to 3 days ahead and store it in the fridge. Simply cover tightly and refrigerate until ready to use. When you're ready to complete the soup, whisk in the milk and cheese as directed in Step 3.

This time-saving trick works especially well for meal prep—just assemble the full soup when you're ready to serve. The roux maintains its flavor and thickening power perfectly. 💡
