Ingredients
- 1 lb (450 g) ground beef, lean or 85% lean
- 2 lb (900 g) russet or Yukon Gold potatoes, peeled and cut into 1-inch (2.5 cm) pieces
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 1 cup (240 ml) beef broth
- 1 tbsp (16 g) tomato paste
- 1 tsp Worcestershire sauce
- 1 tsp dried Italian seasoning
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper
- 1 cup (115 g) shredded cheddar cheese, optional, for topping
- 2 tbsp (30 ml) chopped fresh parsley, optional, for garnish
Ingredient Notes
Russet potatoes break down slightly and thicken the sauce, while Yukon Gold potatoes hold their shape a bit better. Either works well. Lean ground beef keeps the dish from becoming greasy. Tomato paste and Worcestershire add depth, so the sauce tastes savory rather than flat.
Equipment You’ll Need
- A 5 to 6 quart (5 to 5.7 L) slow cooker
- A large skillet
- A wooden spoon or spatula
- A cutting board and sharp knife
- A colander for draining fat, if needed
How to Make Slow Cooker Beef and Potato Casserole
- Peel the potatoes and cut them into 1-inch (2.5 cm) pieces. Place them in the bottom of the slow cooker so they form an even layer. Potatoes that are cut to a similar size will cook at the same rate.
- Heat a large skillet over medium-high heat. Add the ground beef and break it into crumbles with a spoon. Cook for about 5 to 7 minutes, until no pink remains and the meat is browned.
- Drain off most of the fat. Add the onion and garlic to the skillet and cook for 2 to 3 minutes, until the onion softens and turns translucent.
- Stir in the tomato paste, Italian seasoning, salt, and black pepper. Cook for about 1 minute, until the paste darkens slightly and smells fragrant.
- Spread the beef mixture over the potatoes in the slow cooker. Pour the beef broth and Worcestershire sauce over the top. Do not stir, so the potatoes stay in place on the bottom.
- Cover and cook on Low for about 6 to 8 hours, or on High for about 3 to 4 hours. Cooking times vary by slow cooker, so start checking at the earlier end of the range. The casserole is done when the potatoes are fork-tender and the beef reached 160°F (71°C) if you use a food thermometer.
- If the sauce looks thin, remove the lid and let it cook uncovered for 15 to 20 minutes on High. If you want a thicker texture, gently mash some of the potatoes against the side of the cooker.
- Sprinkle with cheddar cheese, cover for 3 to 5 minutes until melted, and garnish with parsley if using. Taste and adjust the salt before serving.
Pro Tips for the Best Results
- Brown the beef before adding it. This builds flavor and helps you drain excess fat.
- Cut the potatoes evenly so they finish cooking at the same time.
- Do not lift the lid often. Each time you open it, the cooker loses heat and extends the cooking time.
- Add cheese at the end, not at the start, so it melts smoothly instead of separating.
- Season at the end. Broth and Worcestershire can make the sauce saltier as it reduces.
Common Mistakes to Avoid
Crunchy potatoes: Potatoes in a slow cooker need time. If they are still firm, keep cooking and check again in 30 minutes. Cutting them smaller also helps.
Watery sauce: Slow cookers hold moisture. Use the 1 cup of broth as written, and simmer uncovered for a short time if the sauce seems thin.
Greasy texture: Ground beef releases fat. Drain it before adding the rest of the ingredients.
Variations and Substitutions
- Ground turkey: Works well for a lighter version. Add a splash of olive oil if the turkey is very lean.
- Smoked paprika: Add 1/2 tsp for a smoky flavor.
- Vegetable add-in: Stir in 1 cup (130 g) frozen peas or sliced carrots during the last hour.
- Cheese swap: Use Monterey Jack or a sharp cheddar blend.
Serving Suggestions
Serve the casserole in deep bowls with crusty bread for dipping. A simple green salad with a vinegar-based dressing balances the richness. Fresh parsley or chives add color and a bright finish.
Storage and Reheating
Refrigerate leftovers in an airtight container within two hours of cooking. Use within 3 to 4 days. To reheat, warm portions in the microwave or on the stove over medium heat, adding a splash of broth if the sauce has thickened. Freezing is possible, but potatoes can change texture after thawing, so the dish is best eaten fresh.
Frequently Asked Questions
Can I make this casserole ahead of time?
You can brown the beef and chop the potatoes the night before. Store them separately in the refrigerator, then assemble and cook the next day.
Can I use beef chuck instead of ground beef?
Yes, but you will need to cut the chuck into small cubes and brown it well before adding it. Cooking time will be longer, so check that the meat is tender before serving.
Why are my potatoes mushy?
They may have been cut too small or cooked too long. Use larger, evenly sized pieces and check for doneness earlier.
Can I freeze this casserole?
Freezing is possible, but potatoes can become grainy after thawing. If you freeze it, store in a sealed container for up to 2 months and reheat gently.
