Bertucci's Sausage Soup Copycat Recipe: Smoky Bacon Velout With Celery Crown Crunch

Bertucci's sausage soup copycat recipe delivers that iconic smoky, savory depth you crave in every spoonful. The secret lies in slow-cooked bacon velouté and perfectly seasoned sausage, creating a rich broth that's both hearty and comforting.

I've replicated the restaurant's signature technique of building flavor layer by layer, starting with crispy bacon and ending with that signature celery crown crunch.

The foundation of this soup is a rich, smoky broth made from bacon and sausage, simmered until the flavors meld together beautifully. We'll use Italian sausage for that authentic taste, combined with celery, carrots, and onions for a classic mirepoix that forms the base of the soup.

The key is patience—allowing everything to simmer until the vegetables are tender and the broth is deeply flavorful.

What makes this recipe special is the velouté texture achieved through careful reduction and the addition of a touch of cream at the end. The result is a soup that's both rich and smooth, with the perfect balance of smoky, savory, and slightly sweet flavors.

The celery crown crunch adds a delightful textural contrast that's impossible to resist.

This copycat recipe captures all the elements that make Bertucci's sausage soup so beloved—from the smoky bacon flavor to the comforting velouté texture and the signature celery crown crunch.

It's a soup that's perfect for chilly days or whenever you need a comforting meal. Let's get started on creating this restaurant-quality dish at home.

Ingredients for bertucci's sausage soup copycat

Smoky bacon, Italian sausage, and velouté texture—this copycat captures Bertucci's signature soup perfectly.

The bacon is non-negotiable for that signature smoky depth. Thick-cut bacon from Costco or Whole Foods gives the best flavor—don't skimp. Italian sausage should be sweet or spicy, but Johnsonville or Albertsons brand are reliable grocery store options. Celery crown crunch requires fresh, crisp stalks—avoid those rubbery ones. For the broth, low-sodium chicken brothKing Arthur or Gold Medal brands stay clump-free when whisked.

No thick-cut bacon? Regular bacon cut into thick slices works in a pinch. Italian sausage unavailable? Substitute Italian-style ground beef with Italian seasoning. Fresh thyme unavailable? Dried works at one-third the amount. The celery crown crunch can be made ahead—just store it separately until serving. For extra richness, half-and-half instead of milk adds more body. The velouté flour should be whisked into cold cream first to avoid lumps—trust me on this.

Bacon keeps 1 week in the fridge, sausage 2 weeks frozen. Celery crowns stay crisp for 3 days in the fridge if stored in a sealed container. The velouté soup reheats beautifully—simmer gently to avoid breaking the emulsion. Portion into 6-8 servings for easy leftovers. Freeze soup portions for up to 3 months—just thaw overnight in the fridge.

Step-by-step instructions for Bertucci's sausage soup copycat recipe

Here's how to recreate that signature smoky, velvety soup with restaurant-quality depth.

In a large Dutch oven, cook the 12 oz thick-cut bacon over medium heat for 12-15 minutes, stirring occasionally, until deep golden brown and crispy. The bacon should render about 3 tablespoons of fat—this is your flavor foundation. Remove the bacon with a slotted spoon and set aside, leaving the fat in the pot.

Increase heat to medium-high and add the 1.5 lb Italian sausage, sliced into rounds. Cook for 5-6 minutes, breaking up the meat with a wooden spoon, until lightly browned and cooked through. The sausage should lose its raw pink color completely. Here's the thing—don't rush this step. Proper browning develops that deep, smoky flavor that makes this soup stand out.

Add the diced yellow onion, sliced carrots, 1-inch celery pieces, and minced garlic to the Dutch oven. Stir to combine and cook for 6-8 minutes until the vegetables soften and the garlic becomes fragrant (not browned). You want them to lose their sharp edges but still hold their shape—this prevents a mushy soup texture.

Sprinkle in the 1 tbsp all-purpose flour and stir for 1 minute to coat the vegetables. This creates a light roux that will thicken the broth later. If the mixture looks dry, add 1-2 tablespoons of the rendered bacon fat to help it blend smoothly. The flour will absorb into the vegetables, forming a flavorful base for the soup.

Pour in the 6 cups chicken broth, scraping up any browned bits from the bottom of the pot. Add the 2 whole bay leaves, 1 tsp dried thyme, 1.5 tsp salt, and 0.5 tsp black pepper. Bring to a gentle boil, then reduce heat to low and let it simmer uncovered for 20 minutes. This allows the flavors to meld while the vegetables cook down slightly.

After 20 minutes, taste the broth and adjust seasoning if needed. The soup should be flavorful but not overly salty. If it's too thin at this point, you can remove one of the bay leaves to reduce bitterness. The broth should be rich and aromatic, with the vegetables just tender but still holding their shape. This is the moment that matters—proper seasoning now ensures balanced flavor throughout.

Stir in the 0.5 cup heavy cream and 0.25 cup whole milk to create that signature velvety texture. Simmer for 5 minutes on low heat—don't let it boil, or the cream will curdle. The soup should thicken slightly and develop a luxurious mouthfeel. If it's too thick, whisk in 1-2 tablespoons of hot broth to reach your desired consistency.

Remove the 2 bay leaves before serving. Ladle the soup into bowls and garnish with the crispy bacon and a celery crown from the 1 whole celery stalk (cut into a 1-inch thick round). That celery crown adds a satisfying crunch that contrasts beautifully with the creamy broth. Serve immediately while the soup is hot and the bacon is crisp.

For the perfect celery crown, select the 1 whole celery stalk with the largest diameter. Trim the ends and cut a 1-inch thick round using a sharp chef's knife. The crown should be flat on one side and rounded on the other. This simple garnish not only adds texture but also enhances the visual appeal of your soup, making it look just like the restaurant version.

I know it seems like an extra step, but trust me—this little detail elevates the dish from homemade to restaurant-quality. The contrast between the creamy soup and the crisp celery crown is what makes this copycat recipe so satisfying. Plus, it's a fun way to use up the leftover celery stalk without wasting anything.

Dietary considerations for this bertucci's sausage soup copycat

Gluten-Free Adaptations

The original recipe uses all-purpose flour for the velouté, but you can easily make it gluten-free by substituting 1 tbsp gluten-free all-purpose flour blend (like Bob's Red Mill 1:1) or 1 tbsp cornstarch instead.

Whisk it into the cold cream first to prevent clumping, just like the original method. The texture will be slightly lighter but still velvety when simmered properly. 🥄

Dairy-Free Options

For a dairy-free version, replace the heavy cream and whole milk with ½ cup full-fat coconut milk (canned, not cartoned) and ¼ cup unsweetened almond milk. The coconut milk adds richness while keeping the velouté texture, though it will have a subtle coconut flavor.

For extra creaminess, stir in 2 tbsp nutritional yeast after simmering. The bacon and sausage will still provide plenty of savory depth.

Low-Carb Adjustments

To make this soup keto-friendly, skip the flour entirely and use 2 tbsp butter instead to thicken the broth slightly. Replace the heavy cream with ½ cup heavy whipping cream and omit the milk.

For extra flavor, add 1 tbsp Worcestershire sauce (check for gluten-free brands) to the simmering broth. The celery crown remains a great low-carb garnish, as celery is naturally low in carbs.

Vegetarian Substitutions

For a meat-free version, replace the 1.5 lb Italian sausage with 1 lb vegan sausage crumbles (like Beyond Meat or Field Roast) or 1 lb mushrooms (cremini or portobello) sliced into rounds.

Increase the garlic to 6 cloves for extra depth. Use vegetable broth instead of chicken broth, and add 1 tsp smoked paprika to mimic the smoky flavor from the bacon and sausage.

Allergen Considerations

This recipe contains common allergens like dairy, gluten, and meat. For an allergen-friendly version, use the gluten-free and dairy-free adaptations above. If you're serving guests with shellfish allergies, ensure your broth doesn't contain any seafood-based additives.

Always check labels on Italian sausage—some brands contain wheat or dairy. For nut allergies, avoid coconut milk and use oat milk instead of almond milk if needed. 💡
