This slow cooker 3-ingredient onion soup pork packets recipe is my go-to when I’m slammed at work and still want a real dinner on the table. My sister actually taught me this trick when I called her one night, standing in my kitchen with zero time and even less energy. The whole idea is beautifully simple: you toss just three ingredients into individual foil pouches, seal them up, and let the slow cooker do the rest. The pork turns out insanely tender, soaked in that classic onion soup flavor, and cleanup is basically tossing the foil. It’s the kind of low-effort, high-reward meal that feels like a little magic on a busy weeknight.
These onion soup pork packets are super versatile, so I usually serve them with something that can cook or reheat easily while the slow cooker does its thing. They’re great over buttery mashed potatoes, egg noodles, or simple white rice to soak up all the savory juices from the packets. Add a quick side salad, steamed green beans, or roasted frozen veggies for color and crunch. If you’re really leaning into the no-fuss vibe, serve the pork shredded on toasted buns with a side of pickles and chips for an easy sandwich night.
Slow Cooker 3-Ingredient Onion Soup Pork PacketsServings: 4
Ingredients
2 to 2 1/2 pounds boneless pork (pork loin, pork shoulder, or thick pork chops), cut into 4 equal portions
1 (1-ounce) packet dry onion soup mix
1 (10.5-ounce) can condensed cream of mushroom soup (or cream of chicken soup)
Directions
Prepare the slow cooker and foil: Set out a 6-quart slow cooker. Tear off 4 large sheets of heavy-duty aluminum foil, each about 12 to 14 inches long. You want enough foil to fully wrap and seal each pork portion into its own packet.
Portion the pork: Cut the boneless pork into 4 roughly equal pieces so each person gets their own packet. Pat the pork dry with paper towels to help it brown slightly and hold onto the seasoning better.
Mix the sauce: In a medium bowl, stir together the dry onion soup mix and the can of condensed cream of mushroom soup until well combined. It will be thick, almost like a paste—that’s exactly what you want. No extra water or broth is needed; the pork will release plenty of juices as it cooks.
Assemble the foil packets: Place one piece of pork in the center of each sheet of foil. Spoon 2 to 3 generous tablespoons of the onion soup mixture over the top of each piece, spreading it to mostly cover the meat. Use all of the mixture, dividing it as evenly as you can among the four packets.
Seal the packets: Bring the long sides of the foil up and over the pork so the edges meet in the center. Fold the edges together tightly a couple of times to seal, then roll up the short ends to close the packet completely. You want the packets sealed well so the steam and juices stay inside and tenderize the meat.
Arrange in the slow cooker: Place the sealed foil packets seam-side up in a single layer in the slow cooker. If needed, you can slightly overlap or stand a packet on its side, but try to keep them as flat as possible so they cook evenly. The tops of the foil packets should be visible when you look down into the slow cooker, similar to little wrapped bundles.
Cook low and slow: Cover the slow cooker with the lid. Cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the pork is very tender and easily pulls apart with a fork. Thicker cuts or pork shoulder may lean toward the longer end of the time range.
Rest briefly: Once the pork is done, turn off the slow cooker and let the packets sit, covered, for about 5 to 10 minutes. This helps the juices settle a bit so they don’t spill out as soon as you open the foil.
Serve from the packets: Carefully lift the hot foil packets out of the slow cooker using tongs. Open each packet slowly, pulling the foil back from your face to avoid the burst of steam. Serve the pork straight from the foil over your choice of potatoes, rice, or noodles, spooning the onion soup gravy from the packet over the top. If you like, you can sprinkle a pinch of dried parsley or dried thyme on top for a little color, just like you’d see in a cozy slow cooker photo.
Variations & Tips
You can easily tweak this three-ingredient base to fit what you have on hand while keeping the no-fuss spirit. Swap the cream of mushroom soup for cream of chicken or cream of celery for a slightly different flavor. If you prefer chicken, use boneless, skinless chicken thighs or thick chicken breasts instead of pork, and check for doneness a bit earlier (around 4 to 6 hours on LOW or 2 1/2 to 3 1/2 hours on HIGH, depending on thickness). For a little extra depth without adding true new ingredients, you can lightly season the pork with salt and black pepper before adding the soup mixture, or sprinkle a pinch of dried herbs like parsley or thyme over the top of the sealed packets right before starting the slow cooker. For meal prep, assemble the foil packets the night before, place them on a tray in the fridge, and in the morning simply transfer the wrapped packets into the slow cooker and press start. Food safety tips: Always keep raw pork refrigerated until you’re ready to assemble the packets, and don’t leave the filled packets sitting out at room temperature for more than 30 minutes. Make sure the slow cooker is set to LOW or HIGH (never “keep warm” for cooking from raw). Pork should reach an internal temperature of at least 145°F, though for shoulder or tougher cuts you’ll usually go higher for tenderness. Discard any leftover foil and do not reuse it; transfer cooled leftovers to clean, airtight containers and refrigerate within 2 hours. Leftover pork can be reheated thoroughly and used for sandwiches, grain bowls, or quick lunches.
