Slow Cooker Shepherd’s Pie is an easy way to enjoy a classic casserole. Fork-tender roast beef simmered with veggies & topped with cheesy mashed potatoes.

Shepherd’s Pie is Matt’s favorite dinner. I don’t make it nearly enough for him, but when I do, I make this Slow Cooker Shepherd’s Pie and the whole family is thrilled when I do.

This is one of those slow cooker recipes that is not necessarily fix and forget, but it is classic comfort food and one of those delicious recipes that’s just worth it.

Why you’ll love this Slow Cooker Shepherd’s Pie Recipe:

  • It’s made with roast beef. Fork-tender, simmered in the slow cooker in a 100% from-scratch sauce with veggies. Anytime roast beef replaces regular ground beef in a recipe, it’s instantly a hit.
  • It’s topped with cheesy mashed potatoes. I think my family now thinks that cheese needs to be added to mashed potatoes every.single.time.
  • It’s thick and stew-like. Add just a few tablespoons of flour towards the end of baking and the sauce thickens right up to the consistency of stew.

Ingredients for Crockpot Shepherd’s Pie

  • Chuck Roast. Chuck roast is marbled and full of flavor. When you let it simmer all day in the crockpot, it falls apart and is fork tender. It makes such as delicious gravy.
  • Mushrooms. I won’t lie. I often leave mushrooms out of this recipe because several in our family are not fans. But if you dice the mushrooms, it’s also hard to tell they are there.
  • House seasoning. This is a mixture of garlic powder, onion powder, black pepper and salt created by Samantha from Five Heart Home. The recipe notes in the recipe card below show exactly how to mix it. It’s great to keep on hand to add to soups and stews.

How to Make Shepherd’s Pie in a Slow Cooker

  • Place the beef cubes in a large slow cooker. Top with the garlic, carrots, mushrooms and corn.

  1. Cover the slow cooker and cook on low for 7 to 9 hours, or on high for 3 ½ to 4 ½ hours, until the beef is tender.
  2. To make the mashed potatoes, place the potatoes in a large saucepan and cover them with 2 inches of water. Bring the potatoes to a boil over high heat and stir in the salt. Reduce the heat and simmer until the potatoes are tender when stabbed with a fork (start checking them at 15 minutes).
  3. Drain the potatoes and return them to the pot. Add the milk, butter, salt and pepper to taste. Gently mash the potatoes with a handheld potato masher.

  2. In a small bowl, mix the flour and 6 tablespoons (90 ml) water until smooth, then slowly stir the mixture into the slow cooker.
  3. Add the peas. Adjust the seasonings to taste with salt and pepper.

Shortcut

Homemade mashed potatoes are unbeatable. In fact, this is a great way to use up leftover mashed potatoes.

But if you are short on time, make instant potatoes with our best instant potato recipe. This makes this slow cooker dish into a fast, easy recipe!

Make it a meal.

​With meat, veggies and potatoes, this classic recipe is a meal in one pot. If you’d like to add side dishes, try one of these:

And how about some peanut butter mousse for dessert?

Freezer Meal Prep

A friend from church told me she prepares this as a freezer meal, and since she mentioned it, I do it too! Here’s what to do:

  • Slow cook the meat and veggies together as the recipe states until the beef is pork tender. Add the peas, flour and water to thicken, then mix.
  • Allow the beef mixture to cool, then place it in an airtight container or ziplock storage bag. Freeze for up to 2 months.
  • When you’re ready to serve the shepherd’s pie, allow the beef mixture to thaw, place it in a baking dish and top with mashed potatoes. Bake for 30-40 minutes at 350ºF or until the beef and potatoes are heated through.

Notes

  • Recipe Source: Real Food Slow Cooker Suppers
  • This House Seasoning Recipe is as follows: ¼ cup fine sea salt, 
    ¼ cup garlic powder, 2 tablespoons onion powder, 1 tablespoon black pepper. Mix these together in a small bowl and store the House Seasoning in an airtight container.
  • Switch up the meat if you’d like. Try ground turkey, ground lamb, or even lean ground beef. Make sure ground meat is lean so that there isn’t too much fat.
  • Freezer meal prep. Slow cook the meat and veggies together as the recipe states until the beef is pork tender. Add the peas, flour and water to thicken, then mix. Allow the beef mixture to cool, then place it in an airtight container or ziplock storage bag. Freeze for up to 2 months.

Hello! I’ve made this before, but I see you updated the post. You mentioned that the recipe card has the instructions for the House Seasoning. It did when I made it before, but now it doesn’t. Help, please! I’m getting this prepped now. Thank you.

I made this, but adding the mashed potatoes for the last 30 minutes kind of made it all mush together. Can you just broil the potatoes and add them on top when everything is cooked?

Or, did I do something wrong?

Just made this recipe. I do not think I am a big fan of it. I followed directions exactly. It is way to tomato-ey. It was also very hard to scoop out to put on a plate. As soon as you take the first scoop out the rest of it just goes everywhere and makes a big mess. I was really excited to try this recipe so I am a bit disappointed.

I’m making this tomorrow for my family! Should the beef chuck be frozen or thawed?

My mother-in-law is originally from Scotland. I am an educator. She always made the best gravy with BISTO. Try it for sauces and gravy.

Making this right now and it looks great! Do you happen to know strictly the amount of ingredients needed for the house seasoning in this recipe? Don’t want to waste extra ingredients I don’t need, thanks 🙂
