Comfort Casserole – French Onion Shepherd’s Pie

I am a fan of all-in-one-dish casseroles, but the rest of my family, well, not so much. So variations of shepherd’s pie only appear here once every few years. And this year, right now, is the time!

First, a little history. What I have always considered Shepherd’s Pie is in fact Cottage Pie. Around since the late 18th century, both are baked savory meat dishes with mashed potatoes as a topping. Shepherd’s pie is an Irish dish made with lamb or mutton. Cottage pie is an English dish that uses beef for the protein. Here in the States, beef is typically the meat of choice, and the two names are used interchangeably, with shepherd’s pie being the preferred moniker.

This variation has 3 main ingredients: ground beef, mashed potatoes, and caramelized onions. The directions include making the mashed potatoes, but the dish can be assembled using 3 cups of previously made mashed potatoes. The onions will take some time, but It is important to cook them slowly to maximize the sugars and flavor of the onions.

As for the other iterations of shepherd’s pie we have enjoyed, Mushroom Shepherd’s Pie is a vegetarian option, Turkey & Leek Shepherd’s Pie will use up some of those turkey leftovers in a few weeks, and Sweet Potato Shepherd’s Pie is an awesome twist on the more traditional casseroles!

It looks like way too many onions, but they really cook down!

Directions:

Preheat oven to 375°F. In a large skillet, sauté the onions in oil until softened.

Start cooking the onions, low & slow.

Reduce the heat to medium-low and cook for 35-40 minutes or until the onions are a deep golden brown color, stirring occasionally.

It takes some time, but it is worth it!

Meanwhile, to a large pot, add the potatoes with enough water to cover them by 1″ and bring them to a boil over high heat. Reduce the heat to low and simmer the potatoes for 15-20 minutes, until they are fork tender.

Cook the potatoes in enough water to cover them by an inch.

When the potatoes are cooked, drain them well and mash them in the pot. Add the butter and mix it in. Add enough milk to make the potatoes smooth.

Add the butter and enough milk to make the potatoes smooth.

In a large skillet, cook the beef over medium heat until it is no longer pink, breaking up any chunks.

Cook the beef, breaking up the chunks.

When the beef is cooked through, crumble the beef and drain the fat off. Return the pan to the heat and stir in the flour and 1/2 teaspoon of salt until it is well blended. Cook for 1 minute longer.

Add the flour and salt to the beef.

Combine the broth, brandy, Worcestershire sauce, and mustard.

Mix together the broth, brandy, Worcestershire sauce and mustard.

Gradually stir the sauce into the pan. Bring the beef mixture to a boil, cooking and stirring for 5 minutes, until thickened.

Stir the sauce mixture into the beef.

Transfer the beef mixture to a greased 8-inch square baking dish. Spread the caramelized onions evenly over the top of the beef.

Add the beef mixture to the prepared baking dish and spread the onions over top.

Spread the mashed potatoes over top of it all.

Cover the beef & onions with the mashed potatoes.

Sprinkle the cheese evenly over the top.

Add the cheese over top.

Bake, uncovered, for 30-35 minutes or until bubbly and the cheese is melted. If desired, turn the oven to broil and place the baking dish under it for about 3 minutes, until the top is golden brown.

Another incredible casserole!

Serve immediately.
