Crock pot shepherd pie makes the classic shepherd pie recipe even easier, thanks to the crock pot. Loaded with ground beef, vegetables, and classic seasonings and topped with mashed potatoes, it's an easy weeknight feast the whole family will enjoy.
In a large skillet over medium-high heat. Add ground beef and onions. Cook until beef is browned and onions are soft. Drain off excess grease well.
Add ground beef, onions, rosemary, thyme, black pepper, salt, tomato paste, garlic, peas, and carrots to the slow cooker.
In a medium bowl, add beef broth, Worcestershire sauce, and cornstarch. Whisk until well combined. Pour into the slow cooker and mix everything together.
Cover and cook on low for 5-6 hours or high for 3 hours.
Forty-five minutes before cook time is up. Add potatoes to a large pot of boiling water. Cook the potatoes until fork tender. Drain off the water and add sour cream and butter. Mash until there are no lumps.
Spread evenly over the shepherd's pie filling and top with cheddar cheese. Continue to cook until the cheese is melted—about 15 minutes.
Notes
Cook your ground beef until it's no longer pink and no further. Overcooked ground beef is rubbery, dry, and devoid of flavor.
Cube your potatoes into relatively small chunks. They'll cook faster and mash more easily than larger chunks.
Don't defrost your vegetables before adding them to the crock pot. Cooking them from frozen ensures they don't overcook over the course of the hours they'll spend in the crock pot.
