Au Bon Pain Chicken Noodle Soup Recipe: Herb-Infused Broth with Tender Shreds

This Au Bon Pain chicken noodle soup recipe delivers the same comforting, herb-infused flavors you crave from their iconic bowls—creamy broth, tender shredded chicken, and perfectly cooked noodles.

The secret lies in a rich, roux-thickened base infused with fresh herbs like parsley and thyme, balanced by bright lemon and aromatic bay leaves. I've replicated their signature techniques, including the signature egg drop swirls that give it that restaurant-quality finish.

The recipe begins with a flavorful chicken base, where bones and meat simmer for hours to extract maximum depth. A simple roux made with butter and flour thickens the broth just enough to create that signature velvety texture without heaviness.

Fresh herbs and a touch of lemon brighten the broth, while egg drop swirls add a delicate, silky element that elevates every spoonful.

By the time you're done, you'll have a steaming bowl of soup with tender shredded chicken, perfectly cooked egg noodles, and a broth so flavorful it tastes like it's been simmering all day.

The balance of savory, herby, and slightly tangy flavors makes this soup both comforting and sophisticated—ideal for chilly evenings or when you need a taste of nostalgia.

Serve with optional garnishes like crispy croutons or fresh green onions for extra texture and color. This recipe makes enough for a crowd, so plan to save leftovers for another cozy meal. Let's recreate that Au Bon Pain magic in your own kitchen.

Ingredients for au bon pain chicken noodle soup

Six bowls of cozy comfort—just these 17 ingredients and a little patience.

The chicken is non-negotiable for that Au Bon Pain depth. Bone-in pieces (wings or thighs) add richness, but chicken breasts work too—just don't skip them. I grab mine from Costco when possible, but any grocery store's fresh chicken will do. The carrots and celery should be bright and crisp—Trader Joe's has great pre-chopped veggie mixes if you're short on time. For the herbs, fresh is ideal, but dried thyme at one-third the amount works in a pinch. The bay leaves? Grab a small box from the spice aisle—they keep forever and make all the difference in that aromatic broth.

No fresh parsley? Dried parsley at half the amount gets you close, though it won't be as vibrant. Out of butter? Olive oil works too, but butter's flavor is key here. The egg noodles can be any width, but medium is traditional. For the egg drop swirls, room-temperature eggs are crucial—they blend smoother. Want extra richness? Add a splash of heavy cream at the end. The lemon juice is optional but brightens the whole dish—fresh is best, but bottled works if you're in a hurry. And if you're making a big batch, double the herbs—they mellow as it simmers.

This soup tastes even better the next day, so make extra. Store in the fridge for 4-5 days or freeze portions for 3 months. The egg drop swirls are best made fresh, but you can reheat the broth and noodles separately, then add the swirls at the end. For serving, I like to toast whole-grain bread for croutons—just toss cubes with olive oil and bake until crispy. The leftovers reheat beautifully—just add a splash of water or broth to loosen things up.

Step-by-step instructions for herb-infused chicken noodle soup

Transform simple ingredients into restaurant-quality soup with rich, herb-infused broth and tender chicken.

In a large Dutch oven, combine the 8 cups water, 1 lb chicken wings, 2.5 lb chicken breasts, 1 whole yellow onion, 4 medium carrots, 4 whole celery stalks, 6 cloves garlic, 2 whole bay leaves, 1.5 tsp salt, and 0.5 tsp black pepper. Bring to a rolling boil over high heat, then immediately reduce to a gentle simmer. Skim off any foam that rises to the surface during the first 5 minutes—this ensures a clear, clean broth.

Let the broth simmer uncovered for 45-60 minutes until the chicken is completely tender and the vegetables are easily pierced with a fork. The aroma should be deeply savory with herbal notes from the thyme and bay leaves. Remove the chicken breasts and wings with tongs, reserving the broth and vegetables for later. Strain the broth through a fine-mesh sieve into a clean pot, pressing gently on the solids to extract maximum flavor. Discard the solids.

In the same Dutch oven (no need to wash it—the fond adds flavor), melt the 0.5 cup unsalted butter over medium heat until it foams. Gradually whisk in the 0.5 cup all-purpose flour, stirring constantly for 2-3 minutes until the mixture turns a pale golden color and smells nutty. This roux is the secret to that velvety texture—don't rush it or it'll burn.

Slowly pour in 2 cups of the reserved chicken broth while whisking vigorously to prevent lumps. Cook the mixture for 5-7 minutes until it thickens slightly but remains smooth. Remove from heat and stir in the 2 tbsp lemon juice—this brightens the flavors and balances the richness. Keep the roux warm over very low heat while you prepare the noodles and poached eggs.

Bring a separate pot of 4 cups water to a rolling boil and add the 2 cups egg noodles. Cook according to package directions until al dente (usually 8-10 minutes), then drain and set aside. While the noodles cook, place the 4 large eggs in a bowl and gently whisk them until just combined. Fill a second bowl with cold water and set both aside.

Here's where the magic happens: carefully drop the whisked eggs into the cold water bowl one at a time. After 30 seconds, use a slotted spoon to transfer each egg to the hot broth. They'll poach perfectly—just enough to set the whites while keeping the yolks runny. This technique ensures each spoonful delivers that classic Au Bon Pain experience of creamy egg meeting rich broth.

Return the strained broth to the Dutch oven with the warm roux and bring to a gentle simmer over medium-low heat. Add the cooked egg noodles and the shredded chicken (torn into bite-sized pieces). Stir gently to combine, then adjust the seasoning with additional salt or pepper if needed. The soup should be flavorful but not overpowering—each ingredient should shine.

Ladle the hot soup into bowls, placing 1 poached egg in each. Garnish with the 0.25 cup chopped fresh parsley and 1 tbsp chopped fresh thyme just before serving. The contrast of warm soup, silky egg, and fresh herbs creates that perfect first bite. Serve immediately while the eggs are still perfectly poached—this soup tastes best fresh from the pot!

Storing and reheating this au bon pain chicken noodle soup

Refrigerator Storage

Store your soup in an airtight container (I love Pyrex glass containers for their durability) for up to 4-5 days in the fridge. Let it cool completely before storing to prevent condensation, which can make the broth watery.

The flavors actually deepen overnight as the herbs meld together—trust me, it’s even better the second day! 💪

Freezer Prep Tips

For longer storage, portion the soup into freezer-safe containers or ziplock bags, leaving 1-inch headspace for expansion. Freeze for up to 3 months—just thaw overnight in the fridge before reheating.

Pro tip: Freeze the egg drop swirls separately and add them fresh when reheating to keep that silky texture. 🧊

Reheating Methods

Stovetop reheating is my go-to—simmer the soup over medium-low heat for 10-12 minutes, stirring occasionally. Add 2-3 tablespoons of water or broth if it thickens too much.

For microwave reheating, cover with a damp paper towel and heat in 1-minute intervals on 50% power, stirring between each interval until steaming hot. 🔥

Reviving Texture

If the noodles look dry after reheating, splash in ¼ cup of hot broth or water and let them soak for 2-3 minutes before serving. For extra richness, stir in 1 tablespoon of butter or a splash of heavy cream at the end.

Garnish with fresh parsley and a crack of black pepper to brighten the flavors. ✨

Egg Swirl Refresh

If you froze the soup without the egg swirls, make fresh ones by whisking 1 egg white (or the whites from 2 whole eggs) with 1 tablespoon of hot broth.

Slowly drizzle the mixture into simmering soup while stirring gently—this creates those signature ribbons. Add them just before serving to keep them silky. 🍳

Garnish Like a Pro

Top your reheated soup with toasted croutons (toss cubes of bread with olive oil and bake at 350°F for 8-10 minutes) or chopped green onions for freshness. A sprinkle of fresh thyme or a drizzle of hot sauce adds a restaurant-worthy finish. Serve with crusty bread for dipping! 🥖
