Slow Cooker Shepherd’s Pie Recipe (Classic Comfort Food Made Easy)
Slow Cooker Shepherd’s Pie is a hearty, comforting dish that brings together rich savory flavors, tender meat, and creamy mashed potatoes—all with minimal effort.

This slow cooker version preserves everything people love about the original while making it far more convenient for busy home cooks.

The meat becomes tender, the vegetables absorb the savory gravy, and the herbs infuse the dish evenly. Finished with buttery mashed potatoes, this Slow Cooker Shepherd’s Pie is satisfying, nourishing, and ideal for family dinners, meal prep, or cold-weather comfort meals.
Ingredients
For the Slow Cooker Filling
-
1 ½ pounds ground lamb
-
1 tablespoon olive oil
-
1 medium yellow onion, finely chopped
-
2 medium carrots, diced
-
2 celery stalks, diced
-
3 cloves garlic, minced
-
2 tablespoons tomato paste
-
2 tablespoons all-purpose flour
-
1 cup beef broth (low sodium)
-
2 teaspoons Worcestershire sauce
-
1 teaspoon fresh thyme (or ½ teaspoon dried)
-
1 teaspoon fresh rosemary, finely chopped (or ½ teaspoon dried)
-
1 teaspoon kosher salt
-
½ teaspoon freshly ground black pepper
-
1 cup frozen peas
For the Mashed Potato Topping
-
2 pounds Yukon Gold potatoes, peeled and cut into chunks
-
½ cup whole milk, warmed
-
4 tablespoons unsalted butter
-
¾ teaspoon kosher salt
-
¼ teaspoon black pepper
Step-by-Step Instructions
1. Brown the Lamb
Heat olive oil in a large skillet over medium-high heat. Add the ground lamb and cook for 6–8 minutes, breaking it up as it cooks, until browned and no longer pink. Browning enhances flavor and prevents excess grease. Transfer the lamb to the slow cooker.
2. Cook the Vegetables
In the same skillet, add onion, carrots, and celery. Cook for 5–6 minutes until softened and lightly golden. Add the garlic and cook for 30 seconds until fragrant.
3. Create the Gravy
Stir in the tomato paste and cook for 1 minute. Sprinkle the flour over the vegetables and stir constantly for another minute. Gradually pour in the beef broth, stirring until smooth and slightly thickened.
4. Season and Slow Cook
Add Worcestershire sauce, thyme, rosemary, salt, and pepper. Stir well, then pour the mixture into the slow cooker with the lamb. Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the filling is thick and flavorful.
5. Make the Mashed Potatoes
About 30 minutes before serving, place potatoes in a large pot of salted water. Bring to a boil and cook for 15–18 minutes, until fork-tender. Drain well, then mash with butter, warm milk, salt, and pepper until smooth and creamy.
6. Assemble the Shepherd’s Pie
Stir frozen peas into the hot lamb filling. Spoon the mashed potatoes evenly over the top, smoothing gently with a spatula. Cover and cook on HIGH for 15–20 minutes, just until the potatoes are heated through.
7. Serve
Scoop into bowls, ensuring each serving includes both the savory lamb filling and the creamy potato topping.
