These slow cooker 4-ingredient beef and Brussels sprouts foil packets are what my dad calls his “little silver presents.” He’s been wrapping meat-and-veg bundles in foil since the late ’70s, long before sheet-pan dinners were trendy. The beauty here is in the simplicity: seasoned ground beef and halved Brussels sprouts get tucked into individual foil packets, stacked into a slow cooker, and left to gently steam and roast in their own juices. With only four ingredients and almost no prep, this is an easy, hands-off meal that still feels a bit theatrical when everyone opens their own hot packet at the table.
Serve each foil packet directly on a plate, letting everyone peel back the foil and release the fragrant steam. These pair well with crusty bread or dinner rolls to soak up the juices, or a simple buttered rice or mashed potatoes for something heartier. A crisp green salad with a tangy vinaigrette balances the richness of the beef. If you’d like a sauce, offer a small bowl of soy sauce, steak sauce, or a garlicky yogurt on the side for dipping bites of beef and Brussels sprouts.
Slow Cooker Beef & Brussels Sprouts Foil PacketsServings: 4
Ingredients
1 1/2 pounds lean ground beef
1 pound Brussels sprouts, trimmed and halved
2 tablespoons Worcestershire sauce
1 1/2 teaspoons kosher salt, plus more to taste
Directions
Prepare the foil: Tear off 4 large sheets of heavy-duty aluminum foil, each about 12 to 14 inches long. If using regular foil, double-layer each packet for extra strength. Lightly crimp up the edges to form shallow trays so juices don’t run off while you fill them.
Season the ground beef: In a large bowl, add the ground beef, Worcestershire sauce, and kosher salt. Use clean hands or a fork to gently mix just until the seasoning is evenly distributed, being careful not to overwork the meat so it stays tender.
Portion the beef: Divide the seasoned ground beef into 4 equal portions. Place one portion in the center of each foil sheet and gently press into a thick patty or short log, about 3/4 to 1 inch thick. Leave a border of foil around the meat so you have room to fold and seal.
Add the Brussels sprouts: Divide the halved Brussels sprouts evenly over and around the beef in each packet, piling them on top and to the sides. It’s fine if the packets look full; the sprouts will soften and shrink slightly as they cook.
Seal the packets: Bring the long sides of each foil sheet up over the filling and meet them in the middle. Fold the edges together tightly, then roll and crimp down to seal. Fold and crimp the short ends as well, creating fully sealed rectangular packets that will hold in steam and juices. Make sure there are no large gaps.
Load the slow cooker: Arrange the foil packets seam-side up in the slow cooker crock, stacking them in layers if needed. It’s fine if they overlap; just avoid pressing them down so tightly that you risk tearing the foil.
Cook: Cover the slow cooker with the lid and cook on LOW for 5 to 6 hours, or on HIGH for 3 to 3 1/2 hours, until the beef is cooked through and the Brussels sprouts are tender when pierced with a fork. If you have an instant-read thermometer, the center of the beef should reach at least 160°F (71°C).
Rest the packets: Turn off the slow cooker and let the packets sit, covered, for 5 to 10 minutes. This brief rest allows the juices to settle back into the beef and makes handling the hot packets a bit safer.
Serve: Using tongs, carefully lift the foil packets out of the slow cooker and place one on each plate. Warn everyone that the steam will be hot, then let diners open their “little silver presents” at the table. Taste and sprinkle with a bit more salt if desired before eating.
Variations & Tips
You can customize these foil packets quite a bit while still keeping the spirit of the recipe. For a smoky profile, replace half of the Worcestershire sauce with barbecue sauce and add a pinch of smoked paprika (this technically adds ingredients, but you can offer them as optional). For a more Mediterranean feel, swap the Worcestershire sauce for a splash of balsamic vinegar and a light sprinkle of dried oregano over the Brussels sprouts before sealing. If you prefer smaller bites, use mini meatball-shaped portions of the ground beef instead of patties; just keep them snug together so they don’t dry out. To reduce fat, choose 90% lean ground beef and drain any excess juices that collect in the foil after cooking. For a slightly richer, almost braised texture, you can spoon a tablespoon of water into each packet before sealing to create extra steam. Food safety tips: Always keep raw ground beef refrigerated until you’re ready to assemble the packets, and wash your hands, bowls, and utensils thoroughly after handling it. Make sure the packets are tightly sealed so raw juices don’t leak into the slow cooker; discard any foil that tears and rewrap with a fresh piece. Cook the packets until the internal temperature of the thickest part of the beef reaches at least 160°F (71°C) to ensure it’s fully cooked. Do not leave cooked packets sitting at room temperature for more than 2 hours; refrigerate leftovers promptly in airtight containers and reheat until steaming hot before eating.
