You don't have to use the brand name Bisto if you don't have it, but you will need another powdered/granular gravy that, when combined with water, will make the sauce/gravy in your Shepherds Pie. If you don't have either, look for a recipe that doesn't use a powdered gravy mix
I fell in love with this non-traditional Shepherd's Pie when I was in Dublin. I wish I could remember the name of the pub where I scribbled the chef's recipe onto a tiny napkin. I've made this a few times and it is always delicious. My newest twist is to roast 3 heads of garlic until they are soft and caramelized and then add them to the saucepan with the butter/cream/salt before blitzing everything to a "sauce" to season the potatoes. The additional of Parmesan cheese sprinkled on top of the mashed potato topping also ensure added flavor.
The tenderness of the meat, the quantity and properly seasoned gravy are key to Shepherd’s Pie. If you have the time, roasting the carrots in a low oven for 7 or 8 hours will render them sublime.
This may seem like a lot, but a really good recipe for Shepherd’s Pie will take some extra work
Ingredients
2 pounds 80/20 ground beef, organic if possible
1 cup Vidalia onion, diced
1 cup carrots, diced
1 cup celery, diced (include the freshest leaves if possible)
1 1/2 cup frozen corn kernels
3 cloves garlic; minced
1 tablespoon grey sea salt, then more to taste
2 teaspoons freshly ground black pepper, then more to taste
1/2 teaspoon freshly grated nutmeg
10 ounces beef stock
2 tablespoons butter; mixed with 2 tablespoons flour
2 pounds potatoes; cooked and mashed
Melted butter
Parmesan cheese
Method
Cook ground beef in frying pan until brown. Add onion, carrots, celery, garlic, salt, pepper and nutmeg. Lower heat and cook for 10 minutes or until vegetables are wilted. Add beef broth, bring to a boil. Stir in enough of the butter/flour roux to make a thick gravy to bind the filling. Pour into large shallow baking pan and cool. The filling should be about 1 1/2 inches deep.
Cover the meat mixture in the pan with the corn and then top with the hot mashed or roasted garlic mashed potatoes. Smooth potatoes evenly then drag a fork in lines across the surface to create valleys and mountains. Brush surface with melted butter and sprinkle with Parmesan cheese.
Bake at 325 F for 35-40 minutes or until the filling is hot and bubbling and the potatoes are golden brown and the "mountains" are slightly charred.
