I found actual real live bangers at the grocery store (exciting!)
So I used those instead of any other beef sausage you can find. For this recipe you will need:
8 large baking potatoes, peeled and quartered
2 teaspoons butter, divided
1/2 cup milk, or as needed
salt and pepper to taste
1 1/2 pounds beef sausage
1/2 cup diced onion
1 (.75 ounce) packet dry brown gravy mix
1 cup water, or as needed
Preheat oven to 350.
Bring a large saucepan to a boil and put your peeled potatoes in there- I chop mine first so they soften quicker- and boil until soft, about 20 minutes.
While you're boiling potatoes, heat a medium skillet with butter and place bangers in skillet. Saute until heated through.
Once the potatoes are soft, drain them and place them back into the pot. Mash them with desired amount of butter and milk. Set aside.
Make gravy by package instructions. - If I were you, I wouldn't leave this alone for too long. I walked away from my gravy and next thing I know brown bubbles are boiling over the top. Oops.-
Pour half of your gravy into an 8 x 11 baking dish.
Spread mashed potatoes over top of banger/gravy mixture. Top with salt and pepper to taste.
Stick this bad boy in the oven until the potatoes are golden brown, about 25 minutes. Serve with sauteed onions or mushrooms if you desire.
