Costco Chicken Noodle Soup Recipe: Savory Broth With Tender Chicken and Egg Noodles

There’s a reason Costco’s chicken noodle soup has a cult following, and this version captures that same comforting magic at home. The secret lies in a rich, savory broth that develops deep flavor through slow simmering with aromatics.

What makes this stand out is the combination of tender poached chicken and perfectly cooked egg noodles that soak up the broth without turning mushy. A touch of freshly ground pepper and parsley adds brightness to each spoonful.

The result is a bowl of soup that’s hearty yet light, with chicken that falls apart at the touch of a fork and noodles that maintain their ideal texture. It’s the kind of meal that warms you from the inside out.

This recipe scales easily for feeding a crowd or meal prepping for the week. Here’s how to make it.

Ingredients for Costco Chicken Noodle Soup

Pantry staples and fresh aromatics create this comforting, savory soup everyone loves.

The chicken is the star here. Boneless, skinless thighs stay juicier than breasts after poaching—Costco’s pre-trimmed packs are perfect for this. If using breasts, don’t overcook or they’ll dry out. For the broth, low-sodium chicken broth lets you control the salt level. Swanson or Kirkland brands are reliable and widely available.

Short on time? Rotisserie chicken (shredded) works great—just add it at the end to warm through. No fresh parsley? Dried parsley at half the amount works. If you can’t find egg noodles, any wide pasta like fettuccine or pappardelle will soak up the broth just as well. Skip the pre-cut mirepoix—fresh veggies taste better.

Soup tastes even better the next day once flavors meld. Stores in the fridge for 4-5 days or freezes for 3 months. Reheat gently to avoid breaking the noodles (they’ll soften more with each reheat).

Step-by-Step Instructions for Chicken Noodle Soup

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear the Chicken Thighs

Heat a large pot over medium-high heat and add the 2 tbsp Olive Oil. Season the 1.5 lb Chicken Thighs with 1 tsp Salt and 0.5 tsp Black Pepper, then add to the pot. Sear for 3-4 minutes per side until golden brown and cooked through.

Don’t crowd the pot—work in batches if needed to ensure even browning. The searing step locks in juices and builds a flavor foundation for the broth. Remove the chicken and set aside.

Step 2: Sauté the Aromatic Vegetables

In the same pot, add the diced 1 whole Yellow Onion, sliced 3 whole Carrots, and sliced 3 whole Celery Stalks. Cook over medium heat for 5-6 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.

Add the minced 4 cloves Garlic Cloves and cook for an additional 1 minute until fragrant. This builds the soup’s aromatic base. Stir in the 1 tsp Dried Thyme and the 2 whole Bay Leaves to infuse the broth with depth.

Step 3: Simmer the Broth with Chicken

Return the seared chicken to the pot and pour in the 8 cups Chicken Broth. Bring to a boil, then reduce heat to low and simmer for 20-25 minutes until the chicken is tender and easily shreds with a fork.

This gentle simmer allows the flavors to meld and the chicken to become fall-apart tender. Remove the chicken, shred it into bite-sized pieces, and return it to the pot. Discard the bay leaves.

Step 4: Cook the Noodles and Finish

Add the 8 oz Egg Noodles to the pot and cook for 8-10 minutes, or according to package instructions, until al dente. Stir occasionally to prevent sticking.

The noodles will absorb some of the rich broth, so keep an eye on the liquid level. If it gets too thick, add a splash of water. Taste and adjust seasoning if needed. Stir in the 0.5 cup Fresh Parsley just before serving for a burst of freshness.

Troubleshooting Perfect Results

Broth Too Bland

If your broth lacks depth, it’s likely under-seasoned or under-simmered. I add an extra ½ tsp salt or a splash of soy sauce for umami. Simmer the broth with chicken and aromatics for at least 20 minutes to develop full flavor. 💡

Mushy Noodles

The most common culprit is overcooking. Egg noodles need 8-10 minutes max in the broth. I cook them separately and add just before serving to prevent them from turning to mush. If leftovers are the issue, store noodles separately and add when reheating.

Chicken Dryness

Overcooking chicken thighs is tough—I aim for 165°F internal temperature. If using breasts, reduce simmer time to 15 minutes. For extra juiciness, I shred the chicken and stir it back into the broth right before serving, so it reabsorbs some liquid.

Cloudy Broth

Avoid boiling the broth vigorously, which can break down proteins and create cloudiness. I keep it at a gentle simmer and skim off any foam that rises to the surface. If using store-bought broth, Kirkland Signature or Swanson stay clear and rich.

Vegetables Too Soft

Add carrots and celery during the last 10 minutes of simmering if you prefer them firmer. I like mine tender but still with a slight bite. For extra crispness, sauté them a minute less before adding the broth.

Seasoning Imbalance

Taste as you go—I often find the soup needs more black pepper or a pinch of dried thyme at the end. If it tastes flat, a squeeze of lemon juice can brighten all the flavors beautifully. 🌟
