How to Make Leftover Corned Beef & Cabbage Soup
To make Leftover Corned Beef & Cabbage Soup, start by heating olive oil in a large pot over medium heat.
Add chopped onion and garlic, sautéing until they turn translucent, which should take around 3-4 minutes. Next, add carrots and celery to the pot, cooking for an additional 5 minutes until they start to soften.
Pour in your choice of liquid (chicken broth, beef broth, or reserved cooking liquid) along with 2 cups of water.
Add diced potatoes, thyme, salt, and pepper. Bring the mixture to a boil, then reduce the heat to low and let it simmer for about 15 minutes or until the potatoes are tender.
Stir in chopped leftover corned beef, cooked cabbage, and continue simmering for an extra 10 minutes to blend the flavors.
Taste the soup and adjust the seasoning if necessary. Finally, ladle the soup into bowls and serve it hot.
