Rich velouté, tender chicken, and those signature crispy celery crowns—here's what brings Au Bon Pain's iconic soup to your kitchen.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breast 🍗 | 2 ½ lb | Cut into 1-inch cubes |
| Egg Noodles 🍜 | 12 oz | Medium or wide egg noodles |
| Celery Stalks 🧅 | 4 whole | Trimmed, cut into 3-inch pieces |
| Yellow Onion 🧅 | 1 whole | Medium, peeled and quartered |
| Carrots 🥕 | 4 whole | Medium, peeled and cut into chunks |
| Garlic Cloves 🧄 | 6 cloves | Peeled and smashed |
| Fresh Thyme 🌿 | 2 tbsp | Leaves only, finely chopped |
| Fresh Parsley 🌿 | 1 tbsp | Leaves only, finely chopped |
| Bay Leaves 🌿 | 2 whole | Dried, for simmering |
| Unsalted Butter 🧈 | 4 tbsp | Cold, cubed |
| All-Purpose Flour 🌾 | 4 tbsp | For roux |
| Chicken Broth 💧 | 6 cups | Low-sodium preferred |
| Whole Milk 🥛 | 1 cup | Full-fat for creaminess |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |

The chicken and celery are non-negotiable for that signature texture. Chicken thighs would work too, but breasts stay juicier for this long simmer. Look for fresh celery with crisp stalks—the ones with yellowing ends get mushy. I grab mine from Whole Foods when I can, but the regular grocery store stuff works fine if it's firm. The bay leaves? Don't skip them—they're the secret to that deep herbaceous flavor. For the butter, Plugrá is my go-to, but any good-quality unsalted will do.
No fresh thyme? Dried works at half the amount, but fresh is ideal. Running low on milk? Heavy cream at half the quantity makes the broth even richer. The flour matters here—King Arthur or Bob's Red Mill for the roux to avoid lumps. For the celery crowns, if you're short on time, broil instead of bake—just watch them like a hawk. The chicken broth? Homemade is best, but even the good low-sodium store-bought stuff works in a pinch.
This soup tastes even better the next day—honestly, the flavors meld into something magical. Store leftovers in the fridge for 4-5 days, or freeze for 3 months. I always make a double batch because it disappears fast. For meal prep, portion the broth and noodles separately—reheat the broth first, then stir in the noodles to keep them from getting mushy. The celery crowns? Best eaten fresh—they lose crispness fast, so save those for the day you serve it.
Why You'll Love This Recipe
- Minimal Chopping Required: I swear by the "three-veggie hack" here—just dice the onion, celery, and carrots together in one bowl while the chicken simmers. No measuring cups, no fuss, and the broth still tastes like it simmered for hours.
- Creamy Without the Cream: That velvety texture? Pure magic from the egg noodles and a splash of chicken broth—no heavy cream or butter needed. The carrots and celery soften just enough to melt into the broth, giving it that just-right body.
- Lunchbox Hero: Between us, this is my go-to for packing lunches. The noodles hold up for days, the chicken stays tender, and even my picky teen eats it cold from the fridge. (Yes, even on a Tuesday.)
- Budget-Friendly Staples: You’re using pantry basics—onion, carrots, celery—that last forever. A single chicken breast stretches for four servings, and the noodles cost pennies. Honestly, it’s the kind of soup that makes me feel like I’m feeding a crowd without breaking the bank.
Step-by-step instructions for herb-infused velouté with crispy celery crowns
Here's how to build a velvety, herb-infused broth with that signature Au Bon Pain crunch.
Sear and Cube the Chicken for Maximum Flavor
Pat the 2.5 lb boneless, skinless chicken breast dry with paper towels and cut into 1-inch cubes. Heat 2 tbsp olive oil in a large Dutch oven over medium-high heat. Working in batches, add the chicken cubes and sear for 3-4 minutes per side until golden brown and cooked through to 165°F internally.
This searing step creates a deep, nutty crust that infuses the broth with rich flavor. Don't crowd the pan—leave space between pieces so they develop that perfect crust. Transfer the cooked chicken to a plate and set aside, reserving the browned bits in the pot for later.
Build the Herb-Infused Velouté Base
In the same Dutch oven, add 4 tbsp unsalted butter and let it melt over medium heat. Add the 1 whole yellow onion (quartered), 4 whole carrots (chunked), and 4 whole celery stalks (3-inch pieces). Cook for 8-10 minutes until the vegetables soften and the onions turn translucent.
Add the 6 peeled and smashed garlic cloves, 2 tbsp fresh thyme, 1 tbsp fresh parsley, and 2 whole bay leaves. Stir for 1 minute until fragrant. Sprinkle in the 4 tbsp all-purpose flour and whisk vigorously to coat the vegetables completely. This creates a blond roux that will thicken our velouté beautifully.
Simmer the Broth to Perfection
Gradually pour in the 6 cups chicken broth while whisking continuously to prevent lumps. Bring to a gentle simmer and add the reserved chicken cubes. Partially cover the pot and simmer for 25 minutes, allowing the flavors to meld and the chicken to absorb the aromatic broth.
Here's the thing—don't rush this step. The broth should reduce slightly, becoming more concentrated and flavorful. You'll notice the herbs releasing their essential oils, creating that signature Au Bon Pain herbal depth. Taste and adjust seasoning with 1.5 tsp salt and 0.5 tsp black pepper as needed.
Finish with Creamy Velouté and Crispy Celery Crowns
Remove the chicken from the broth and set aside. Strain the broth through a fine-mesh sieve into a clean pot. Return the broth to medium heat and whisk in the 1 cup whole milk until smooth. Simmer gently for 5 minutes until slightly thickened but still silky.
While the broth simmers, prepare the celery crowns: Heat 2 tbsp olive oil in a skillet over medium-high heat. Toss the 4 whole celery stalks (3-inch pieces) with 0.5 cup panko breadcrumbs until evenly coated. Fry for 2-3 minutes per side until golden brown and crispy. Drain on paper towels and keep warm.
Assemble and Serve with Perfect Noodles
Bring a separate pot of salted water to a boil and cook the 12 oz egg noodles for 2 minutes less than package instructions (they'll finish in the soup). Drain and add them directly to the velouté along with the chicken cubes. Gently fold everything together and adjust seasoning if needed.
Ladle the soup into bowls, garnishing each serving with 2 crispy celery crowns and an extra sprinkle of fresh parsley. The contrast of creamy velouté with crispy celery crowns is what makes this Au Bon Pain classic so special. Serve immediately while the celery crowns are at their crispiest!
Pro Tips For Making Au Bon Pain Chicken Noodle Soup
- Poach Chicken Low and Slow: Skip the boil—simmer the chicken at a gentle simmer (180°F/82°C) in the broth for 18-20 minutes. I used to rush it, and the meat turned out dry and stringy. Trust me, patience here means the chicken will shred like butter.
- Mince Onion and Celery Fine: Dice the onion into 1/8-inch pieces and chop the celery into matchsticks—no big chunks. This isn’t just for looks; it makes the soup taste richer because the flavors meld faster. (Yes, it takes 30 seconds longer, but it’s worth it.)
- Salt the Water Like the Sea: The broth needs at least 1 teaspoon of salt per quart of water before adding the chicken. I learned this the hard way—watery, bland soup is no one’s idea of comfort food. Taste it halfway through cooking; adjust if needed.
- Add Noodles Last, Stir Once: Cook the egg noodles separately for 1 minute less than package instructions, then toss them into the hot soup and give it one quick stir. This keeps them from turning mushy and lets you adjust the soup’s thickness at the end. (Pro move: reserve 1/2 cup broth to thin if needed.)
Make-ahead tips for this recipe
Broth Prep Ahead
Make the velouté base up to 2 days in advance—it actually tastes better! After simmering the broth (Step 3), let it cool completely, then store in an airtight container in the fridge.
When ready to serve, simply reheat over medium-low heat, whisk in the milk, and adjust seasoning. The flavors deepen as it rests, becoming more concentrated and aromatic. 💫
Celery Crown Prep
These crispy crowns are best made fresh, but you can prep them a day ahead. After frying, let them cool completely, then store in a single layer on a wire rack (not stacked) to maintain crispness.
Reheat in a 350°F oven for 3-4 minutes just before serving. Trust me, they'll still have that satisfying crunch. ⏰
Noodle Prep Shortcut
Cook the noodles ahead and store them separately in the fridge for up to 2 days. When reheating, add them directly to the hot broth for just 1-2 minutes—this prevents that dreaded mushy texture.
I like to portion them into individual containers so I can grab and go when soup time comes. 🍜
Freezer-Friendly Components
For long-term storage, freeze the broth separately from the chicken and noodles. The broth keeps for 3 months in a freezer-safe container. When ready to serve, thaw overnight in the fridge, then reheat with the milk. Add fresh noodles and chicken when reheating to maintain perfect textures. 🧊
Chicken Prep Trick
Cut the chicken into cubes and store them in the fridge for up to 1 day before cooking. This makes assembly day much faster. When ready to use, simply sear them as directed—no need to thaw if you're cooking immediately.
The cold chicken will cook through evenly during the simmering process. 🍗
Complete Soup Assembly
When you're ready to serve, combine all components in a pot and heat through for just 5-7 minutes—this is where the magic happens! The velouté will thicken slightly, and the chicken will absorb all those wonderful flavors.
Garnish with fresh parsley and crispy celery crowns right before serving for that restaurant-quality presentation. ✨

Frequently asked questions
Why does Au Bon Pain chicken noodle soup have crispy celery crowns?
The celery crowns are a signature element that adds a delightful textural contrast to the creamy velouté. They're made by coating celery pieces in panko and frying until golden—this creates a satisfying crunch that balances the soup's richness. The technique comes from Au Bon Pain's focus on multi-textured comfort food.
Can I make this soup vegetarian?
Replace the chicken with 12 oz extra-firm tofu or 1.5 cups chickpeas for protein. Use vegetable broth instead of chicken broth, and add 1 tsp smoked paprika for depth. The velouté base and celery crowns remain exactly the same—just swap the protein component.
What's the secret to the velouté being so creamy?
The creamy texture comes from two key techniques: a proper blond roux (butter + flour) and the milk finish. The roux creates a smooth base, while the milk adds richness without making it heavy. Simmering the broth gently after adding milk thickens it naturally—don't overcook or it'll curdle. The secret is patience!
Can I use store-bought rotisserie chicken instead?
Yes! Shred 2 cups cooked rotisserie chicken and add it to the soup during the final 5 minutes of simmering. For extra flavor, use the chicken's broth (about 1 cup) to replace some of the water in your recipe. The texture will be slightly different but still delicious—just avoid overcooking the chicken to prevent dryness.
How do I fix soup that's too thick or too thin?
For thin soup, simmer uncovered for 5-10 minutes to reduce. For thick soup, whisk in 1 tbsp cornstarch mixed with 2 tbsp cold water and simmer for 2 minutes**. Never add flour directly—it can create lumps. The velouté should coat a spoon but still be silky, not gluey.
