What Ingredients are in Corned Beef Soup?
This hearty Corned Beef Soup combines savory deli meat with classic aromatics and vegetables, all wrapped up in a flaky puff pastry crust.

Every ingredient plays its part – from the mustard that adds a subtle tang to the chicken stock that forms the soul of this comforting soup.

- 6 slices bacon, cut into 1/4-inch pieces
- 1 1/4 cups finely chopped onions
- 1 cup sliced carrots
- 6 russet potatoes, peeled and cut into 3/8-inch cubes
- 5 cups chicken stock

When shopping for this recipe, the quality of your corned beef matters. A thick-cut deli slice works perfectly, giving you those satisfying meaty bites without having to cook a whole brisket. The puff pastry should be completely thawed before working with it, so plan ahead and move it from freezer to refrigerator the night before. And don’t skip that egg wash—it’s what gives the pastry that irresistible golden-brown shine that makes everyone at the table reach for their phones to snap a picture before diving in.

How to Make this Corned Beef Soup
Start by crisping up 6 slices of bacon (cut into 1/4-inch pieces) in a soup pot over medium heat. This creates that irresistible flavor base that makes this soup so special.
Once the bacon is crisp, toss in 1 1/4 cups of finely chopped onions and let them cook with the bacon for about 2 minutes, just until they begin to soften. The bacon fat works magic here, coating everything with savory goodness.
Next, add 1 cup of sliced carrots and 6 peeled, cubed russet potatoes to the pot, giving everything a good toss to coat with those bacon-y flavors.
Cover the pot, reduce the heat to low, and let this mixture cook for just 3 minutes. Then pour in 5 cups of chicken stock and 2 tablespoons of Dijon mustard, stirring until well combined.
Now comes the star of the show – 1/2 pound of corned beef cut into strips. Season with 1 teaspoon each of salt and pepper (adjusting to taste), cover, and let everything simmer gently for about 20 minutes until the vegetables become tender.
For perfect, evenly chopped vegetables that cook uniformly, consider using a high end food processor to prep your ingredients.
Meanwhile, prepare your puff pastry tops by cutting 4 rounds from each sheet of thawed pastry, making them about an inch wider than your serving dishes. Don’t forget to cut a small steam vent in the center of each round!
When the soup is ready, ladle it into eight 1-cup ramekins, leaving about 1/2 inch of space at the top.
Brush the pastry rounds with an egg wash (1 egg whisked with 1 teaspoon of cold water), and place them egg-side down over the ramekins. Press the edges firmly against the outside of each dish – careful not to press down from the top or you’ll tear the dough!
Brush the tops with more egg wash for that gorgeous golden finish, then refrigerate for at least an hour before baking at 400°F for 18-20 minutes.
The moment those pastry tops puff up and turn golden brown, you’ll understand why this soup is called “under cover” – it’s like unwrapping a delicious present at the dinner table.
Corned Beef Soup Substitutions and Variations
Making this hearty corned beef soup your own couldn’t be easier, with plenty of flexibility to adapt it to your pantry and preferences.
Swap chicken stock for beef broth for a deeper flavor, or use vegetable stock for a lighter note. Not a mustard fan? Try horseradish instead for that signature zing.
Don’t have corned beef? Leftover ham, pastrami, or even rotisserie chicken works beautifully.
The puff pastry can be replaced with pie crust or even a simple biscuit topping if you’re in a pinch. Sweet potatoes offer a lovely alternative to russets, lending a hint of sweetness.

What to Serve with Corned Beef Soup
While this corned beef soup creates a complete meal with its puff pastry top, you’ll want some perfect accompaniments to round out your dinner experience.
I love serving a crisp green salad with a light vinaigrette to balance the rich, savory flavors of the soup. Think peppery arugula or butter lettuce with thin slices of radish and a sprinkle of fresh herbs.
A side of quick-pickled vegetables adds brightness and acidity. Can’t go wrong with pickled onions or cucumbers here.
For beverages, a robust dark beer or dry cider complements the corned beef beautifully. Nothing fancy, just thoughtful pairings.
