Servings: 6
🛒 Ingredients
- 1 ½ pounds frozen ground beef crumbles
- 1 cup plain powdered milk
- 4 medium russet potatoes, peeled and sliced thin
- 1 medium yellow onion, sliced thin
- 1 tin (300g) condensed cream of mushroom soup
👩🍳 Directions: Slow Cooker Beef and Potato Bake
- Get the slow cooker ready. Rub a little oil or cooking spray inside a 6-quart slow cooker so nothing sticks. Lay down half of your sliced potatoes on the bottom, like a blanket. Then sprinkle half of the sliced onions on top of the potatoes.
- Add the beef. Take your frozen ground beef crumbles and spread them out evenly over the potatoes and onions. Try to cover the whole surface so every bite gets some meat.
- Layer it again. Place the rest of your sliced potatoes on top of the beef, followed by the rest of the onions. You should now have two full layers of potatoes, onions, and beef in the middle.
- Make the creamy sauce. In a medium mixing bowl, add the powdered milk, the can of cream of mushroom soup, and 2 cups of water. Whisk everything together until it looks mostly smooth, with just a few small lumps left.
- Pour it over the top. Slowly pour the creamy mixture over the layers in the slow cooker. Make sure it spreads evenly and covers the very top layer so nothing dries out while cooking.
- Cook low and slow. Put the lid on the slow cooker. Cook it on LOW flame about 7 -8 hrs, or on HIGH heat for 4 -5 hours. By this stage, the potatoes will have turned tender right through, and the beef should be cooked completely, with no trace of pink remaining.
- Press it down (optional). If you’re home partway through cooking, gently press the top layer down with a spoon. This helps keep the potatoes soaked in the creamy liquid so they cook evenly.
- Let it rest. Once done, take the lid off and let the casserole sit for 10 to 15 minutes. This gives the sauce time to thicken up a bit before you serve it.
- Serve and enjoy. Scoop generous portions onto plates while it’s still warm, and enjoy this cozy, old-fashioned dinner!
