Step 10

In a lightly oiled and preheated stainless steel pan, place ground lamb (or ground beef if you prefer). Break it up in the pan until brown. Drain any excess fat, but leave 2-3 Tbsp in the pan.- 1 pound ground lamb (or ground beef for cottage pie)

Step 11

Add the finely minced onion and saute for 2-3 minutes, until soft and translucent around the edges. Add the carrots and saute them for 2-3 minutes.- ½ large onion- 4 medium carrots

Step 12

Make a hole in the middle of the pan and add the crushed garlic and tomato paste.- 3 cloves garlic (peeled)- Tomato paste

Step 13

Mix together and saute for 2-3 minutes. Add the chopped rosemary and thyme and stir.- Rosemary sprigs- Thyme sprigs

To make the sauce, add flour to the mixture and mix until the raw flour smell is gone and a fond has formed on the bottom of the pot (about 2-3 minutes).- 1 tbsp flour

Step 15

Deglaze with dark Irish Stout and beef’s broth. Make sure to scrape up all the fond at the bottom while mixing. Add a few dashes of Worcestershire sauce. Optional: now is when you can add Madeira and frozen demi-glace if you have it.- 1 cup Dark Irish Stout- 1 cup bone broth- Worcestershire sauce- 1 tbsp Madeira (optional)- 1 puck frozen Demi Glace (optional)

Step 21

Even out the potatoes with an offset spatula. Use a fork to rough it up to make sure there are enough nooks and crannies that will brown and get crispy.

Set the pie plate on a sheet of parchment paper set in a rimmed baking sheet. Place in a 350°F oven for about 25 minutes. Remove at the 15 minute mark to top with more grated cheddar (optional) and place back in the oven for the remaining 10 minutes. You can also broil it the last 2-3 minutes for extra brown and crispy.
