Costco Chicken Noodle Soup Recipe: Big-Batch Comfort in One Pot

There’s something deeply comforting about a big pot of chicken noodle soup simmering on the stove. This recipe takes inspiration from Costco’s beloved version but delivers a homemade depth of flavor that can’t be matched.

The secret lies in a slow-simmered broth, tender shredded chicken, and hearty egg noodles that soak up every bit of flavor. I’ve streamlined the process to keep it simple while ensuring restaurant-quality results every time.

What you’ll get is a rich, aromatic soup with perfectly cooked vegetables and noodles that are never mushy. The broth is velvety, the chicken is juicy, and the overall effect is pure comfort in a bowl.

Perfect for feeding a crowd or storing for lazy days ahead. Here’s how to make it.

The chicken is key here. Costco sells pre-packaged boneless thighs that work perfectly—just trim any excess fat. I like a mix of thighs and breasts for texture (thighs for richness, breasts for shredding). For the veggies, fresh carrots and celery give the best flavor, but frozen works in a pinch. Grab the egg noodles from the dry pasta aisle—Reames or No Yolk are solid choices.

No chicken broth? Better Than Bouillon paste mixed with water is a great backup. Swap dried parsley for fresh at one-third the amount. Thyme can be fresh too—just double the quantity. Out of egg noodles? Fettuccine or wide rice noodles hold up well. The bay leaves are important though—don’t skip them. If you’re short on time, rotisserie chicken works (about 4 cups shredded).

This soup tastes even better the next day. Store in the fridge for up to 4-5 days or freeze for 3 months. I like to portion it into quart-sized containers so it’s ready for lazy nights. The noodles will absorb more broth over time—add a splash of water when reheating.

Step-by-Step Instructions for Costco-Style Chicken Noodle Soup

This one-pot method delivers hearty, comforting soup with minimal effort and maximum flavor.

Step 1: Sauté the Aromatic Base

Heat the 2 tbsp Olive Oil in a large pot over medium heat. Add the diced Yellow Onion, chopped Carrots, and chopped Celery Stalks with their leaves. Cook for 5-6 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.

This is where the flavor foundation builds. I always let the veggies cook until they start to smell sweet—that’s your cue they’re ready. Add the minced Garlic Cloves and cook for another 30 seconds until fragrant. Don’t let the garlic brown or it’ll turn bitter.

Step 2: Brown the Chicken and Build the Broth

Increase heat to medium-high and add the 2 lb Chicken Thighs and 1 lb Chicken Breasts (cut into bite-sized pieces if using). Brown the chicken for 5-6 minutes, stirring occasionally, until it loses its raw color and starts to develop golden edges.

Pour in the 8 cups Chicken Broth, then add the 2 whole Bay Leaves, 1 tsp Dried Thyme, 1 tsp Salt, and 0.5 tsp Black Pepper. Stir well and bring to a boil. Once boiling, reduce heat to low and let it simmer for 20 minutes to infuse the flavors.

Step 3: Shred the Chicken and Add Noodles

Remove the chicken pieces with a slotted spoon and transfer them to a cutting board. Once cool enough to handle, shred the chicken into bite-sized pieces using two forks. Return all the shredded chicken to the pot—this ensures every spoonful has plenty of protein.

Add the 8 oz Egg Noodles to the simmering broth. Cook for 8-10 minutes until the noodles are tender but still slightly firm. Stir occasionally to prevent sticking. The noodles will absorb some of the broth, making it richer and more substantial.

Step 4: Finish and Serve

Remove the Bay Leaves from the pot. Stir in the 1 tbsp Dried Parsley and taste for seasoning. Adjust with more Salt or Black Pepper if needed—I usually find it needs just a bit more salt at this stage.

Ladle the soup into bowls while it’s hot. The broth should be steaming and fragrant, with visible flecks of herbs and vegetables. This is comfort in a bowl—thick with noodles, packed with tender chicken, and loaded with classic flavor. Serve with crusty bread for the full experience.

Dietary Considerations for This costco chicken noodle soup

Gluten-Free Option

Swap the 8 oz Egg Noodles for gluten-free pasta like Jovial or Barilla brown rice noodles. Add them to the simmering broth and cook for the time listed on the package, usually 7-9 minutes. 💪

Dairy-Free Adaptation

This recipe is naturally dairy-free, but double-check your Chicken Broth label for hidden dairy derivatives. I recommend Imagine Foods or Pacific Foods brands for guaranteed dairy-free options. The flavor remains just as rich and comforting.

Lower-Carb Version

Replace the noodles with zucchini noodles or spaghetti squash. Add them during the last 5 minutes of cooking to prevent mushiness. You’ll get the same hearty feel with fewer carbs and an extra serving of veggies.

Vegetarian Twist

Use chickpeas or tofu instead of chicken for a plant-based version. Sauté 2 cups diced tofu or 2 cans drained chickpeas with the vegetables. Swap chicken broth for vegetable broth to keep it fully vegetarian.

Low-Sodium Adjustments

Use low-sodium Chicken Broth and reduce the added Salt to ½ tsp. Boost flavor with extra herbs like fresh rosemary or sage. Taste as you go and adjust seasoning at the end. 🌿

Allergy Notes

This soup is naturally free from nuts, soy, and fish. For celiac safety, ensure your broth and noodles are certified gluten-free. Always check labels if allergies are severe, as manufacturing processes can vary by brand.
