⏱️ Prep Time: 20 minutes
🔥 Cook Time: 7–8 hours on LOW or 4–5 hours on HIGH
🍽️ Servings: 4
🍲 Slow Cooker: 6-quart
🛒 Ingredients
- 2 lb (900 g) boneless beef chuck, cut into 1-inch chunks
- 4 medium yellow potatoes, sliced into ¼-inch rounds
- 8 oz (225 g) fresh mushrooms, thickly sliced
- 1 small yellow onion, sliced into half moons
- 4 garlic cloves, finely minced or grated
- 4 tablespoons (57 g) unsalted butter, divided into 4 portions
- 1 teaspoon salt, or to taste
- ½ teaspoon black pepper, or to taste
- 4 large sheets heavy-duty aluminum foil
👩🍳 Instructions
1. Season the Beef
Pat the fully thawed beef chunks dry with paper towels. Season with salt and black pepper, tossing gently to coat. Keep the beef raw; browning is not necessary.
2. Prepare the Foil Packets
Cut four large sheets of heavy-duty aluminum foil. Arrange them on your work surface and divide the potato slices evenly among the four sheets.
3. Add the Vegetables
Layer the sliced mushrooms and onions over the potatoes, distributing them evenly between the packets.
4. Add the Beef
Place an equal portion of seasoned raw beef chunks on top of the vegetables in each packet.
5. Add Garlic Butter
Divide the minced garlic evenly among the packets. Place one tablespoon of butter on top of each beef portion.
6. Seal the Packets
Bring the foil edges together and fold securely, sealing both ends while leaving a little room inside for steam circulation. Make sure the cooking juices remain contained.
7. Arrange in the Slow Cooker
Place all four packets snugly inside a 6-quart slow cooker, with the folded seams facing upward. Make sure the lid closes completely.
8. Slow Cook
Cover and cook:
- LOW: 7–8 hours
- HIGH: 4–5 hours
Cook until the beef is fork-tender and the potatoes are completely soft. Cooking times may vary depending on your slow cooker and the size of the beef pieces. Check that the beef reaches a safe internal temperature.
9. Open and Serve
Carefully transfer each packet to a dinner plate. Open the foil away from your face to avoid the hot steam. Keep the potatoes underneath, mushrooms and onions in the middle, and tender beef on top.
Spoon the delicious garlic-butter juices over everything and serve warm!
