Easy Shepherd's Pie with Instant Mashed Potatoes Recipe - Unfussy Kitchen (1)

Shepherd’s Pie, isn’t it just the best casserole dinner? The gravy, the mashed potato topping, the ground beef filling… So many childhood memories for me.

These days, I don’t have the time to whip one up completely from scratch – which is why I always reach for this quick prep, easy, shortcut version. It’s made with instant mashed potatoes, brown gravy mix and condensed cream of mushroom soup. Apart from browning the beef, you don’t need to do any cooking before the casserole hits the oven!

By the way, fun fact: Authentic Shepherd’s Pie is actually made with ground lamb, not beef. Which is also why it’s called a “Shepherd’s Pie”. My recipe is totally for an American version of Shepherd’s Pie with ground beef, most of us call it “Sheppards Pie” anyways, so does it really matter? 😉

Ingredients you’ll need

This is just an overview of the ingredients needed – scroll to the recipe card at the bottom for exact quantities and instructions.

Ingredient notes

  • Condensed cream of mushroom soup: If you don’t like the condensed mushroom soup, condensed cream of onion or bacon work as well.
  • Frozen mixed vegetables: I prefer a classic mix with corn, peas, diced carrots and green beans. Feel free to use any frozen vegetables you like, but I do recommend using bite-sized vegetables.
  • Instant mashed potatoes: Use your favorite variety here. Whenever I’m at a store that carries a “complete” instant mash, I’ll absolutely grab it to make life even easier. Remember to have milk and butter (or any ingredients the box calls for) on hand to whip up the mash if you’re using instant mashed potatoes that don’t say “complete” on the box.

Step by step photos

This recipe is too easy! Once you browned the beef in a large skillet, just stir in the brown gravy mix, the condensed cream soup and the beef broth. Then, fold in the frozen mixed vegetables. Done!

Spread this in a large casserole dish (mine is a little under 9×13 inches), top with mashed potatoes and cheese and bake!

It’s best to let the casserole sit on the counter for 10 minutes before serving, to let the gravy thicken a little. It’s hard, but worth it 😉

See? This is almost too easy to call dinner! Almost.

Recipe tips

  • No need to let the beef cool down before adding the remaining ingredients to the filling – it’s actually easier to stir it up while the beef is hot!
  • If you want perfectly separate layers, you’ll need to let the filling cool down completely before adding the mashed potatoes. I pretty much never bother, but for the perfectionists among us 😉
  • Feel free to adjust the amount of potatoes to your taste. We like a thick layer of potato, so if you want a thin layer, reduce the amount of mashed potatoes.

Make ahead instructions

You can make ahead the filling up to 3 days. Just place it in the casserole dish, let cool to room temperature for 30 minutes and cover with foil. Refrigerate for up to 3 days.

To bake, remove the casserole from the fridge and uncover. Let sit on the counter while the oven preheats. Top with mashed potatoes and cheese and bake as directed in the recipe, or until heated through and bubbly.

I do not recommend freezing the casserole, as the cream soup can split after being frozen. Feel free to try, I have never bothered to try because the dish is so quick to whip up.

Serving suggestions

I love Shepherd’s Pie, because it’s a complete meal! If you wanted a side for a special meal, I recommend sautéed green beans, corn on the cob or glazed carrots.

If you’re a salad person, a bean salad or a tossed green salad are nice, too!
