There are few things more comforting than the smell of chicken soup simmering on the stove. It’s the kind of recipe that instantly quiets the noise of the day — warm, savory, and grounding in the best possible way. Growing up, chicken soup wasn’t just a meal; it was an event. The kitchen filled with the soft bubbling of a pot that never seemed to stop giving. Every hour it simmered, the flavors deepened, and the whole house felt wrapped in that cozy, golden aroma.

This recipe takes that same old-fashioned comfort and adds a quiet twist — sourdough discard. It’s an ingredient that would have surprised my grandmother, but I think she would’ve appreciated the thrift of it. The discard adds a delicate body to the broth, thickening it just enough to feel rustic without turning it heavy. And that faint tang from the sourdough? It rounds out the chicken’s richness in a way that feels like it’s been there all along.
This is the kind of soup you make when you want your kitchen to smell like home — when you want to remind yourself that simplicity, when done right, can be extraordinary.
This is the kind of cozy, nourishing meal that pairs perfectly with comforting sides like my Brown Butter Honey Biscuits or a slice of Easy Honey Cornbread for soaking up every last bit of that rich broth.

Onion (quartered)
Adds depth and subtle sweetness.

Garlic
Enhances the overall flavor with warmth and depth without overpowering the broth.
Salt
Essential for building flavor at every stage—start early and adjust at the end.
Whole Black Peppercorns
Infuse the broth with gentle heat and complexity without making it overly spicy.
Bay Leaves
Add subtle herbal depth and that classic “homemade soup” flavor.

Instructions

- Step 1: Combine all spices and chicken into a large pot and bring to a gentle boil.

- Step 2: After simmering for 2 hours strain out vegetables (remove bay leaves) and blend up with a small amount of broth. Then return to broth.

- Step 3: Chop vegetables and put them into the pot, simmering for 15 minutes.

- Step 4: Pull out a cup of broth and mix with sourdough discard until smooth, then return to pot and let simmer for 10 minutes.
Step-by-Step Instructions
1. Simmer the Broth
Place your whole chicken in a large stockpot and add 12 cups of water. Toss in the onion (leave the peel on for color), carrots, celery, garlic, salt, peppercorns, bay leaves, and thyme. Bring to a gentle boil, then reduce to a low simmer.
Let it bubble quietly for 1½ to 2 hours, skimming off foam occasionally. The slower the simmer, the clearer and more flavorful your broth will be.
2. Strain and Shred
Once the chicken is tender and falling off the bone, carefully remove it from the pot and set it aside to cool. Strain the broth through a fine-mesh sieve into another pot, blending all vegetables (except bay leaves) along with a cup of broth. Then returning it to broth base. This creates an EXTRA flavorful broth base.
When the chicken is cool enough to handle, shred the meat into bite-sized pieces. Discard the skin and bones (or save them for a second round of broth).
3. Build the Soup
Return your broth to the pot and bring it back to a gentle simmer. Add the diced potatoes and chopped carrots, letting them cook for about 15–20 minutes until tender.
4. Incorporate the Sourdough Discard
In a small bowl, whisk your sourdough discard with a ladleful of hot broth until smooth. Slowly stir it back into the pot. You’ll see the broth take on a soft, creamy body — the kind that feels like it’s been cooking all day.
The discard blends seamlessly, adding subtle flavor without making the soup taste “bready.”
5. Combine and Adjust
Add your shredded chicken back into the pot and simmer for another 5 minutes. Taste and adjust the salt, adding more as needed. If you want a touch of brightness, add a small splash of apple cider vinegar right at the end.
6. Serve and Enjoy
Ladle the soup into bowls and serve with a sprinkle of fresh parsley or thyme. It’s lovely on its own, but even better with a slice of warm sourdough for dipping.
Variations
1. Root Vegetable Medley:
Swap the potatoes for parsnips or turnips for a slightly earthier flavor.
2. Lemon-Herb Twist:
Add the zest of one lemon and a handful of chopped dill right before serving for a springlike freshness.
3. Creamy Comfort:
For a richer soup, stir in ½ cup of cream or coconut milk at the end. It pairs beautifully with the tang of the sourdough discard.
4. Grain Boost:
Add a handful of cooked rice, quinoa, or barley to make it extra filling.
5. Brothy Reset:
If you prefer a lighter broth, skip the potatoes and double the carrots — perfect for sipping when you’re under the weather.

Serving Suggestions
- Serve with a thick slice of buttered sourdough or a hunk of crusty gluten-free bread.

- Refrigerate: Store leftovers in an airtight container for up to 5 days.
- Freeze: The soup freezes beautifully. Let it cool, then store in quart-size freezer bags or containers for up to 3 months.

FAQs
Does this soup taste sour because of the sourdough discard?
No. Once cooked, the sourdough discard mellows completely and adds depth rather than sourness. It lightly thickens the broth and enhances the savory flavor without overpowering it.
Can I use active sourdough starter instead of discard?
Yes. Active starter will work, but it may add a slightly more pronounced tang. Discard is preferred for a more subtle, balanced flavor.
Is this soup really gluten-free?
Yes—as long as your sourdough starter is gluten-free and all ingredients used are certified gluten-free.
Can I make this without blending the vegetables?
Absolutely. Blending adds richness and body, but you can skip it if you prefer a clear, traditional broth. The soup will still be flavorful, just lighter in texture.
Why This Recipe Works
Building flavor from the ground up
Starting with a whole chicken creates a deeply rich, homemade broth that you simply can’t get from shortcuts. As it simmers, the bones, meat, and aromatics release layers of flavor that form the backbone of this soup.
Low and slow simmering for clarity and depth
Keeping the heat gentle allows the broth to stay clear while developing a clean, balanced flavor. This technique prevents bitterness and gives you that classic, golden homemade soup.
Layered vegetables for better texture
Some vegetables are cooked into the broth for flavor, while others are added later to maintain their shape and texture. This creates a soup that’s both rich and hearty—not mushy or flat.
Blended vegetables for natural body
Blending a portion of the cooked vegetables back into the broth thickens it naturally without cream or flour, giving the soup a silky, slightly rich texture while keeping it wholesome.
