Cook’s Notes for Corned Beef Cottage Pie

I used Yukon Gold yellow-fleshed potatoes for my mashed potatoes. You could also use Russets, if you like.

If you’d like, you can make the mashed potatoes ahead and cover and refrigerate. If you can, take them out of the fridge a bit early, so they can come up to room temperature before baking.

Top Tip! Be sure not to skip the step of reducing the liquid in the skillet before adding the corned beef. This process concentrates the flavours of the Worcestershire and Ketchup and make for a fuller flavoured finished dish.

After you have added the corned beef, simmer the mixture until there is just a bit of liquid in the pan, but don’t cook it until ALL the liquid has evaporated. This will keep your corned beef layer moist as it cooks in the oven.

The cheddar cheese and breadcrumb topping is optional. You can skip if you like and you will still have a very nice dish. Since I’ve never been one to “skip the cheese”, I usually add it :)

My favourite way to eat this is with a generous dollop of ketchup on the side, if you’d like to try that.

At my house, this dish served 2. Me and a very, very hungry husband. I’ll call it 3 servings, as it is more like 3 average servings. If you are serving more, just double the recipe and cook up in a larger dish.

How to Cook a Corned Beef Brisket

Starting with an uncooked corned beef brisket, you can cook it either on the stove-top or in a slow cooker. Simply remove the brisket from it’s wrapping. Place in a large pot or slow cooker and cover with about 1 inch of water. If your corned beef came with a separate spice pack, add spices to the water.

On the stove-top, bring to a boil, then reduce heat and simmer, covered, for about 50 minutes per pound of corned beef. For the slow cooker, cook for 4 1/2 hours on HI or 8-9 hours on LOW.

Mashed Potatoes:

  • 1 lb potatoes peeled and quartered, about 4 medium-sized potatoes)
  • 1/3 cup milk
  • 2 Tbsp butter
  • Salt to taste

Corned Beef Filling:

  • 2 Tbsp butter
  • 1 cup onion diced
  • 1 tsp Worcestershire Sauce
  • 1 1/2 Tbsp ketchup
  • 1 1/2 cup chicken broth can use beef broth
  • 2 Tbsp fresh parsley finely chopped (or 1 Tbsp dried)
  • 1/4 tsp dried thyme

  • Salt and freshly ground pepper

Topping (optional):

  • 1/2 cup cheddar cheese shredded
  • 3 Tbsp dried bread crumbs or 1/4 cup fresh bread crumbs


  1. Make the Mashed Potatoes: Add peeled, cut potatoes (evenly sized) to a large pot of cold water. Add salt to the water. Bring to a boil over high heat and cook until potatoes are tender, 10-20 minutes, depending on the size of the potatoes.
  2. Meanwhile, heat milk and butter in a small saucepan over low heat until warm, then keep warm until needed.
  3. Drain then return potatoes to dry pot. Place over medium heat on the stove top. Add milk/butter mixture to the pot. Mash potatoes until smooth. *Add a bit more milk, if needed. Taste and add salt and freshly ground pepper, to taste. Cover and set aside (or cover and refrigerate if making ahead).
  4. Preheat the oven to 400F.
  5. Make the Filling: Heat 2 Tbsp butter in a large skillet over medium heat. Add the onions and cook until softened and starting to turn golden a bit. Add the Worcestershire, ketchup, chicken broth, parsley and thyme to the skillet. Simmer over medium heat until liquid reduces by half. Add the corned beef and reduce heat slightly. Simmer 3-4 minutes or until there is only a bit of liquid left in the mixture (don't let all of it cook off). Taste the mixture and add additional salt and freshly ground pepper, as needed.
  6. Spoon filling into a small baking dish (8-inch round-ish). Spoon mashed potatoes over-top in an even layer. Top with shredded cheese, then sprinkle with bread crumbs.
  7. Bake in preheated oven for about 30 minutes, or until filling is heated through and bubbling and top is lovely and golden.
