Ingredients
- 2 cups leftover cooked corned beef, shredded (about 8 oz)
- 1 cup leftover cooked cabbage (chopped if necessary)
- 1 large onion, finely chopped
- 4 cloves garlic, minced
- 1 lb ground beef or lamb (optional for vegetarians)
- 2 tbsp tomato paste
- 2 cups beef broth
- 1 tsp Worcestershire sauce
- Salt and pepper to taste
- 3 medium potatoes, peeled and cubed
- 1/4 cup milk (or plant-based alternative)
- 2 tbsp butter
- 1/2 cup chopped fresh parsley (optional for topping)
Instructions
- 1
Preheat your oven to 375°F. Get it warm while you prepare the ingredients.

In a large skillet, sauté the onion and garlic in olive oil until translucent, about 5 minutes. Add the ground beef or lamb and cook until browned.

Stir in tomato paste, leftover corned beef, cabbage, beef broth, Worcestershire sauce, salt, and pepper. Simmer for about 10-15 minutes until the mixture thickens slightly. Taste and adjust seasoning if needed.

Meanwhile, boil potatoes in a large pot of salted water until tender, approximately 15-20 minutes. Drain and return them to the pot. Add milk and butter and mash until smooth.

Spoon the beef and cabbage mixture into a 9x13-inch baking dish. Spread the colcannon on top in an even layer, creating peaks for that classic shepherd's pie look.

Bake for about 20-25 minutes or until the top is golden brown and bubbly. Sprinkle with fresh parsley before serving.
So you’ve got leftover corned beef and cabbage sitting in your fridge, staring back at you like a challenge. What’s better than turning those leftovers into a comforting shepherd's pie with a creamy colcannon topping? Let’s do this.
Why This Recipe is Awesome
- It's all about versatility—you can make it with leftover corned beef or add fresh ground meat for a hearty meal.
- Crispy and creamy—the crusty, golden-brown top contrasts beautifully with the soft, saucy center.
- Perfect leftovers—leftovers taste even better the next day when reheated. You won’t be scraping them off your plate.
Common Mistakes to Avoid
- Thinking you can skip preheating the oven—you’ll end up with a cold and soggy top layer.
- Overmixing potatoes for colcannon—that's what makes it gluey instead of fluffy. Go easy on that masher.
- Not seasoning enough—don’t be shy with salt and pepper in both the filling and topping. It’s key to making everything pop.

Alternatives & Substitutions
- No ground meat? No worries, you can use more cooked corned beef or a mix of beans for a vegetarian version.
- Out of tomato paste? Use 1/4 cup ketchup mixed with 2 tsp molasses. It gives a similar flavor profile.
- Want it cheesier? Mix some shredded cheddar into the colcannon before topping your pie.
FAQ (Frequently Asked Questions)
Can I use sweet potatoes instead of regular ones for the colcannon? Absolutely! Sweet potatoes will give you an extra touch of sweetness and make a great alternative. Just adjust cooking time as needed.
Do I need to add butter to colcannon? Butter makes it creamy, but if you’re avoiding dairy or want something lighter, use olive oil instead.
How do I store leftovers? Let the pie cool completely before storing in an airtight container in the fridge for up to 4 days. Reheat in a covered dish with a little water added underneath to keep it moist.
