Ingredients You’ll Need

- 2 tbsp butter or oil
- 1 onion, chopped
- 2 carrots, sliced
- 2 celery stalks, sliced
- 3 garlic cloves, minced

How to Make Corned Beef and Cabbage Soup
Step-by-Step Instructions
Step 1: Prepare the Base Heat butter or oil in a large pot or Dutch oven over medium heat. Add the chopped onion, sliced carrots, and celery stalks. Cook for 5-7 minutes, stirring occasionally, until the vegetables begin to soften and the onion becomes translucent.
Step 2: Add Aromatics Add the minced garlic to the pot and cook for another minute until fragrant. Be careful not to let the garlic burn, as this can create a bitter flavor in your soup.
Step 3: Build the Soup Base Pour in the beef or vegetable broth and bring the mixture to a boil. Add the diced potatoes, dried thyme, and dried rosemary. Reduce heat to medium-low and let the soup simmer for 15-20 minutes, or until the potatoes are fork-tender.
Step 4: Add Corned Beef and Cabbage Stir in the diced or shredded corned beef and sliced cabbage. Continue simmering for an additional 5-10 minutes, just until the cabbage is tender but still has a slight bite to it. Overcooking the cabbage will make it mushy and less appealing.
Step 5: Season and Serve Taste the soup and season with salt and pepper as needed. Remember that corned beef is already quite salty, so start with a small amount of salt and adjust accordingly. Ladle the soup into bowls and garnish with fresh chopped parsley for a pop of color and fresh flavor.
Helpful Tips
Choose the Right Corned Beef: If you’re starting with fresh corned beef, cook it until it’s tender enough to shred easily. Leftover corned beef works perfectly and actually saves time in this recipe.
Don’t Overcook the Vegetables: Keep an eye on your vegetables, especially the cabbage. It should be tender but still have some texture. Mushy vegetables can make the soup less enjoyable.
Layer Your Flavors: Building flavors by sautéing the vegetables first creates a more complex and satisfying soup base than simply throwing everything into the pot at once.
Adjust Liquid as Needed: If your soup seems too thick, add more broth. If it’s too thin, let it simmer uncovered for a few extra minutes to reduce and concentrate the flavors.
Details
This Corned Beef and Cabbage Soup serves approximately 4-6 people and takes about 45 minutes from start to finish. The prep time is minimal – about 15 minutes – while the cooking time allows all the flavors to meld together beautifully. The soup is naturally gluten-free and can easily be made dairy-free by using oil instead of butter. Each serving provides a good balance of protein from the corned beef, fiber from the vegetables, and carbohydrates from the potatoes, making it a nutritionally complete meal.
Notes

Broth Selection: While beef broth complements the corned beef flavor beautifully, vegetable broth works well too and creates a slightly lighter soup. You can even use chicken broth if that’s what you have on hand.
Cabbage Varieties: Regular green cabbage works best for this recipe, but you can experiment with savoy cabbage for a more delicate flavor or even add a small amount of red cabbage for color variety.
Make-Ahead Friendly: This soup actually tastes better the next day as the flavors have more time to develop. It’s perfect for meal prep or making ahead for busy weeknights.
Freezer Considerations: While this soup can be frozen, keep in mind that potatoes can become grainy when frozen and thawed. If you plan to freeze portions, consider leaving out the potatoes and adding them fresh when reheating.
Frequently Asked Questions
Can I use fresh corned beef instead of leftover? Absolutely! Cook the corned beef until tender (usually 2-3 hours depending on size), then dice or shred it for the soup. Save some of the cooking liquid to use in place of some of the broth for extra flavor.
How can I make this soup heartier? Add more potatoes, include some barley or small pasta, or throw in additional vegetables like turnips or parsnips. You can also increase the amount of corned beef if you have extra on hand.
What if I don’t have all the herbs? Thyme and rosemary work beautifully together, but you can substitute with other herbs you have available. Bay leaves, oregano, or even a herb blend like Italian seasoning can work in a pinch. Start with smaller amounts and taste as you go.
Can I make this in a slow cooker? Yes! Add all ingredients except the cabbage to your slow cooker and cook on low for 6-8 hours or high for 3-4 hours. Add the cabbage during the last 30 minutes of cooking to prevent it from becoming too soft.
Is this soup keto-friendly? The potatoes make this soup higher in carbohydrates. For a keto version, substitute the potatoes with cauliflower florets or additional low-carb vegetables like zucchini or bell peppers.
Storage Instructions
Refrigerator Storage: Store leftover Corned Beef and Cabbage Soup in the refrigerator for up to 4-5 days. Keep it in airtight containers and let it cool completely before refrigerating.
Freezing: This soup can be frozen for up to 3 months, though the texture of the potatoes may change slightly. Freeze in portion-sized containers for easy reheating. Thaw overnight in the refrigerator before reheating.
Reheating: Reheat gently on the stovetop over medium-low heat, stirring occasionally. You may need to add a little extra broth or water if the soup has thickened during storage. Microwave reheating works too – heat in 1-minute intervals, stirring between each, until heated through.
Food Safety: Never leave soup at room temperature for more than 2 hours. Always cool it quickly by placing the pot in an ice bath if you need to store it soon after cooking.
