Slow Cooker Shepherd’s Pie

Today I have the honor of showcasing a recipe from Samantha at Five Heart Home’s new cookbook titled Real Food Slow Cooker Suppers. If you find yourself using your slow cooker often, this is a cookbook you need to add to your bookshelf. This gorgeous book has 80 family-friendly dinner recipes that call for all real, fresh, unprocessed ingredients.

I’ve made three recipes from this cookbook so far. Pizza pulled pork sandwiches, a Hawaiian chicken sandwich and this Slow Cooker Shepherd’s Pie. They’ve all been a hit.

But this shepherd’s pie?

My husband couldn’t say enough good things about it.

“I know there’s a little competition because this isn’t YOUR recipe, but it’s really, really good,”  he voices to me as he cleans up the last of the beefy slow cooker casserole.

No really, honey. It’s okay to like someone else’s recipe. 🙂


How to Make Slow Cooker Shepherd’s Pie

  1. 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 (as in my shepherd’s pie) in a recipe, it instantly is a hit.
  2. It’s topped with cheesy mashed potatoes. I think my kids now think that cheese needs to be added to mashed potatoes every.single.time.
  3. 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.



Real food.

Nothing processed.





Samantha’s new cookbook is filled with recipes such as this. You can buy this book on Amazon and Barnes & Noble…or wherever books are sold!

Servings 8
Prep Time 30 minutes
Cook Time 9 hours
Total Time 9 hours 30 minutes


  • 1 1/2 pounds boneless beef chuck roast, trimmed and cut into 1-inch cubes 680 g
  • 3 cloves garlic minced
  • 4 medium carrots peeled and cut into 1/4" slices
  • 8 ounces white mushrooms, cleaned and roughly chopped 227 g
  • 1 1/2 cups frozen corn, thawed 217 g
  • 3/4 cup low-sodium beef broth 180 ml
  • 6 tablespoons tomato paste 100 g
  • 2 teaspoons Worcestershire sauce 10 ml
  • 1 teaspoon dried oregano 1 g
  • 1 1/2 tablespoons House Seasoning* 18 g
  • 3 tablespoons all-purpose flour 24 g
  • 1 1/2 cups frozen peas, thawed 240 g
  • Salt and freshly ground black pepper to taste

For the Mashed Potatoes:

  • 2 1/2 pounds russet potatoes peeled and cut into 2-inch pieces
  • 1 teaspoon salt 6 g
  • 1 cup milk, warmed 240 ml
  • 6 tablespoons butter, melted 85 g
  • 1 1/2 cups shredded cheddar cheese 6 ounces
  • Salt and freshly ground black pepper to taste


  • Place the beef cubes in a large slow cooker. Top with the garlic, carrots, mushrooms and corn.
  • In a medium bowl, whisk together the beef broth, tomato paste, Worcestershire sauce, oregano and House Seasoning. Pour the broth mixture over the contents of the slow cooker and stir to combine.
  • 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.
  • 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).
  • 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.
  • Use a large spoon to skim any fat from the surface of the beef and veggie mixture in the slow cooker.
  • In a small bowl, mix the flour and 6 tablespoons (90 ml) water until smooth, then slowly stir the mixture into the slow cooker.
  • Add the peas.
  • Adjust the seasonings to taste with salt and pepper.
  • Mix the cheddar into the mashed potatoes and spread in an even layer over the top of the beef and vegetables.
  • Cover the slow cooker and cook on high for 15-30 minutes, until the gravy has thickened and the mashed potatoes are heated through.



*Many of the recipes in this cookbook call for Samantha's House Seasoning. 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.

A shepherd’s pie is made with lamb. This is a cottage pie.

I have made this twice and it is spectacular. One quick hack though. I put the whole thing under the broiler to brown the potatoes and it really improved their texture. Will be making it again this year as part of St Patrick’s day meals.

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.

Is the pot roast cubes frozen or refrigerated?

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 🙂

Is this recipe good with a bottle, or partial bottle, of Guiness? If so, does it goof up the liquid ratio?

So delicious! I bought a chuck roast trimmed what fat I could and browned it. Then followed the cooking directions. When time was up I pulled the roast out and shredded it with 2 forks into bite size pieces while removing fat from roast. Added the the flour slurry and peas and returned the meat. So delicious can’t say enough about it. Will definitely make it again. Thank you.

My husband and brother had the same reaction as your husband. I simplified by using Idaho instant potatoes ( I didn’t have enough potatoes to make my own) and added the cheese. Very good!

Can I thicken the mixture with corn starch instead of all purpose flour? I have to cook gluten free and I’m not sure if a gluten free flour will yield the same results.

I made this today and I am commenting because I think it is the best thing I’ve ever made in my crockpot. It wasn’t gummy or tasteless … it was perfect. Great recipe.

If you use beef, it then becomes a ranchers pie, lol

Sounds delicious, I can’t edit to give it a try. ????
