This rotisserie chicken and mushroom chicken soup is my fall favorite!

When the leaves start changing and that crisp autumn air settles in, nothing beats a steaming bowl of homemade soup. This rotisserie chicken and mushroom chicken soup is my fall favorite because it combines the rich, savory flavors of tender rotisserie chicken with earthy mushrooms in a soul-warming broth that takes less than an hour to prepare.

Why This Rotisserie Chicken and Mushroom Soup Works

Using rotisserie chicken cuts your cooking time in half while delivering deep, seasoned flavor that would take hours to develop from scratch. The mushrooms add an earthy richness that complements the chicken beautifully, while fresh herbs brighten the entire bowl. It’s comfort food that actually fits into a busy weeknight schedule.

Ingredients

Here’s what you’ll need to create this comforting autumn soup:

• 1 whole rotisserie chicken (about 3-4 pounds)
• 2 tablespoons olive oil
• 1 large yellow onion, diced (about 2 cups)
• 3 medium carrots, sliced into rounds (about 1½ cups)
• 3 celery stalks, chopped (about 1 cup)
• 8 ounces cremini mushrooms, sliced
• 4 ounces shiitake mushrooms, stems removed and caps sliced
• 4 cloves garlic, minced
• 2 tablespoons fresh thyme leaves (or 2 teaspoons dried)
• 1 bay leaf
• 8 cups low-sodium chicken broth
• 1 cup egg noodles (wide or medium)
• 2 tablespoons fresh parsley, chopped
• 1 tablespoon fresh dill, chopped (optional)
• 2 tablespoons heavy cream (optional)
• Salt and freshly ground black pepper to taste
• 1 tablespoon lemon juice

The combination of cremini and shiitake mushrooms creates layers of umami flavor, but you can substitute with whatever mushrooms you prefer or have available.

How to Make It

Follow these straightforward steps to create this warming soup:

1. Prepare the rotisserie chicken: Remove all meat from the rotisserie chicken, discarding the skin and bones. Shred the meat into bite-sized pieces and set aside. You should have about 4 cups of shredded chicken. Save the carcass if you want to make your own stock later.
2. Heat the oil: In a large, heavy-bottomed pot or Dutch oven, heat the olive oil over medium heat. The pot should be large enough to hold all ingredients comfortably, as the soup will expand when you add the broth.
3. Sauté the vegetables: Add the diced onion, carrots, and celery to the pot. Cook for 5-6 minutes, stirring occasionally, until the vegetables begin to soften and the onion becomes translucent. This creates the flavor base for your soup.
4. Add the mushrooms: Add both types of sliced mushrooms to the pot. Cook for 4-5 minutes, stirring frequently, until the mushrooms release their moisture and begin to brown slightly. The mushrooms will shrink considerably as they cook.
5. Add aromatics: Stir in the minced garlic, thyme, and bay leaf. Cook for another minute until fragrant. Be careful not to let the garlic burn, as it will become bitter.
6. Add the broth: Pour in the chicken broth, scraping up any browned bits from the bottom of the pot with a wooden spoon. These bits add tremendous flavor to the soup. Bring the mixture to a boil, then reduce heat to maintain a gentle simmer.
7. Simmer the soup: Let the soup simmer for 15-20 minutes, allowing the vegetables to become tender and the flavors to meld together. The carrots should be easily pierced with a fork when ready.
8. Add the chicken: Stir in the shredded rotisserie chicken and let it heat through for 3-4 minutes. The chicken is already cooked, so you’re just warming it and allowing it to absorb some of the broth flavors.
9. Cook the noodles: Add the egg noodles to the soup and cook according to package directions, usually 6-8 minutes, until they’re tender but still have a slight bite. Stir occasionally to prevent sticking.
10. Final seasonings: Remove the bay leaf and stir in the fresh parsley, dill (if using), and heavy cream (if using). Add the lemon juice, which brightens all the flavors. Season with salt and pepper to taste, keeping in mind that rotisserie chicken can be quite salty.
11. Serve immediately: Ladle the hot soup into bowls and serve right away while the noodles are at their best texture. Garnish with additional fresh herbs if desired.

This method ensures each ingredient contributes its best flavor while maintaining the perfect texture throughout the soup.

How to Serve It

Common Mistakes

Avoid these frequent pitfalls when making this soup:

• Overcooking the noodles: Add noodles during the last few minutes of cooking to prevent them from becoming mushy
• Using too much salt early: Rotisserie chicken and broth both contain sodium, so taste before adding salt
• Not browning the mushrooms: Allow mushrooms to release their moisture and develop color for deeper flavor
• Skipping the vegetable base: Properly sautéing onions, carrots, and celery creates essential flavor foundation
• Adding chicken too early: Since rotisserie chicken is already cooked, add it just to warm through
• Forgetting to scrape the pot: Those browned bits on the bottom add significant flavor when deglazed
• Using only one mushroom variety: Mixing mushroom types creates more complex, interesting flavors
• Not removing the bay leaf: Always remember to fish out bay leaves before serving

Taking care with these details will ensure your soup turns out flavorful and properly textured every time.

Storage and Reheating

Proper storage keeps this soup delicious for several days:

• Refrigerator storage: Store cooled soup in airtight containers for up to 4 days in the refrigerator
• Freezing considerations: The soup base freezes well for up to 3 months, but cook noodles fresh when reheating
• Portion control: Divide into single-serving containers for easy weekday lunches
• Reheating on stovetop: Warm gently over medium-low heat, stirring occasionally to prevent sticking
• Microwave reheating: Heat individual portions in 1-minute intervals, stirring between heating cycles
• Adding liquid: You may need to add extra broth when reheating, as noodles absorb liquid over time
• Fresh herb refresh: Add fresh herbs after reheating to brighten the flavors
• Texture adjustments: If noodles become too soft, consider adding fresh ones during reheating

The soup actually develops more flavor after a day in the refrigerator, making it excellent for meal prep.
