Slow cooker dinners that start with a simple dump-and-go setup are a lifesaver on busy weeknights, and this 4-ingredient beef and pea mash is exactly the kind of hearty, low-effort supper that earns a regular spot in the rotation. It takes a very humble combination of ground beef, canned green peas, and a couple pantry staples and turns them into a cozy, spoonable dish that feels a bit like a rustic cottage pie filling without all the extra prep.
This dish is especially good served with buttery mashed potatoes, crusty bread, or even over toast if you want to lean into its comfort-food vibe. A crisp side salad or simple steamed carrots help brighten the plate, and if you're feeding a hungry family, a little shredded cheddar on top makes it feel even more substantial.
Slow Cooker 4-Ingredient Beef and Pea Mash
Servings: 4
Ingredients
1 pound ground beef
2 cans green peas, undrained, 15 ounces each
1 packet brown gravy mix, about 0.87 ounce
2 cups prepared mashed potatoes
Directions
1. Add the raw ground beef to the bottom of the slow cooker and break it up lightly with a spoon so it covers the base in an even layer.
2. Pour the canned green peas with their liquid evenly over the beef, then sprinkle the brown gravy mix across the top.
3. Cover and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours, stirring once or twice if convenient, until the beef is fully cooked and the mixture is hot and thickened.
4. Stir in the mashed potatoes until everything is well combined into a thick, hearty mash. Taste and adjust with a little salt and pepper if needed before serving.
Variations & Tips
Cheesy version: Stir in 1 cup shredded cheddar at the end for a richer, kid-friendly finish that melts right into the mash.
Make-ahead tip: If mornings are hectic, add the beef, peas, and gravy mix to the slow cooker insert the night before, refrigerate it, and place it into the cooker in the morning. Stir in hot prepared mashed potatoes at the end for the best texture.
Texture tip: For a smoother mash, use creamier mashed potatoes and stir thoroughly. If you prefer more definition between the ingredients, fold the potatoes in gently instead of fully mixing them.
Extra flavor: A little onion powder, garlic powder, or Worcestershire sauce can be added with the gravy mix if you want a deeper savory taste without making the recipe much more complicated.
