Step‑by‑Step Instructions for savory chicken and cabbage soup
Step 1: Prep the Ingredients
Begin by gathering all your ingredients for the savory chicken and cabbage soup. Chop the cabbage into bite-sized pieces, dice the carrots and celery, and mince the garlic. For added convenience, use pre-cooked rotisserie chicken, shredding it into small pieces. This step ensures everything is ready to go as you begin cooking.
Step 2: Sauté the Aromatics
Set a large pot over medium heat and add a tablespoon of oil. Once heated, toss in the chopped onion and garlic, sautéing for about 3-4 minutes until the onions are translucent and fragrant. This base will deepen the flavors in your savory chicken and cabbage soup, providing a wonderful aroma that fills your kitchen.
Step 3: Add the Vegetables
Next, add the chopped cabbage, diced carrots, and celery to the pot. Stir everything together and cook for another 5 minutes, allowing the vegetables to soften slightly and begin to meld with the aromatics. You want the carrots to maintain some crunch, as they will continue cooking later in the savory soup.
Step 4: Incorporate the Broth
Pour in 6 cups of chicken broth and bring the mixture to a gentle boil over high heat. Once bubbling, reduce the heat to low and add your shredded chicken, bay leaf, thyme, and black pepper. Let this simmer for about 15-20 minutes, allowing the flavors to blend beautifully while the cabbage softens, resulting in a comforting soup.
Step 5: Adjust Seasonings and Serve
After simmering, taste the soup and adjust seasonings as needed. If you like a bit of heat, add some crushed red pepper, then remove from heat. Ladle the savory chicken and cabbage soup into bowls, garnishing with freshly chopped herbs like parsley or dill for a pop of color and refreshment. Enjoy the warmth of this comforting dish!
