This 3-ingredient slow cooker pork roast is the kind of no-fuss, big-flavor meal that makes dads grin from ear to ear. It starts with a raw bone-in pork roast, just like the Sunday dinners my own father waited for all week, and leans on two humble pantry secrets—dry onion soup mix and a can of cream of mushroom soup—to do the heavy lifting. Everything goes straight into the slow cooker, no browning or fussing, and by suppertime the meat is tender, the house smells like home, and you have a rich gravy right in the pot. It is a modern shortcut wrapped up in old-fashioned comfort, perfect for Father’s Day or any evening you want to make a man at your table feel especially cared for.
Serve thick slices of the pork roast with plenty of the slow-cooker gravy spooned over the top. This roast is right at home alongside buttery mashed potatoes or egg noodles, a simple pan of roasted carrots, or classic Midwestern sides like green beans and dinner rolls to mop up every bit of sauce. A crisp green salad or tangy coleslaw adds some freshness to balance the richness. For a true Papa’s Day spread, finish with something simple and nostalgic for dessert, like apple crisp or a slice of pie and a cup of coffee.

3-Ingredient Slow Cooker Papa’s Day Pork Roast
Prep Time: 5 minutes | Cook Time: 8-10 hours on LOW or 4-5 hours on HIGH | Total Time:Approximately 8-10 hours
Yield: 6 servings
Ingredients
-
1 (3½ to 4 pound) bone-in pork shoulder or pork butt roast, raw
-
1 (10.5-ounce) can condensed cream of mushroom soup
-
1 (1-ounce) packet dry onion soup mix
Instructions
1. Place the Pork in the Slow Cooker:
Place the raw bone-in pork roast into the bottom of a 5- to 7-quart slow cooker, fat side up if there is a cap of fat. The roast should sit flat in the center of the crock, with the bone nestled down and plenty of space around it for the juices and sauce.
2. Make the Sauce:
In a small bowl, stir together the condensed cream of mushroom soup and the dry onion soup mix until mostly blended. It will be thick and a bit lumpy from the dried onions—that is just fine.
3. Coat the Pork:
Spoon the soup mixture evenly over the top of the pork roast, spreading it so the meat is well coated. Some will fall down around the sides of the roast—that will help make the gravy as it cooks.
4. Cook:
Cover the slow cooker with the lid. Cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the pork is very tender and easily pulls away from the bone with a fork. Avoid lifting the lid during cooking so the roast stays moist and the temperature remains steady.
5. Remove and Slice:
Once the pork is tender, carefully lift the roast out onto a cutting board, using two large spatulas or sturdy forks to keep it from falling apart. Remove and discard the bone and any large pieces of excess fat. Slice or gently pull the pork into large chunks.
6. Serve:
Return the meat to the slow cooker and stir it into the hot gravy, or arrange the slices on a platter and ladle the gravy from the slow cooker over the top. Taste the gravy and adjust seasoning if needed. The soup mix is salty, so you may not need extra salt; add a little black pepper if desired. Serve hot with plenty of gravy and your favorite sides.
Recipe Notes & Pro Tips
Choose the Right Cut: Pork shoulder (also called pork butt) is the ideal cut for this recipe. It has enough marbling and connective tissue to become tender during long, slow cooking. Do not substitute pork loin, which is leaner and will become dry.
Fat Side Up: Placing the roast fat side up allows the fat to render slowly and baste the meat as it cooks, keeping it moist and flavorful.
Do Not Add Extra Liquid: The pork releases its own juices as it cooks, which thin the condensed soup into a perfect gravy. Adding water or broth will result in a thin, watery sauce.
No Need to Brown the Pork: Traditional pot roast recipes call for browning the meat first to develop flavor. This recipe skips that step entirely. The long, slow cooking time and the concentrated flavors of the soup mixes create plenty of depth without the extra work.
Thicker Gravy: If you prefer a thicker gravy, remove the cooked pork, set the slow cooker to HIGH, and whisk in 1 tablespoon of cornstarch mixed with 2 tablespoons of cold water. Cook for 5 to 10 minutes until thickened, then return the meat to the pot.
Food Safety Tips: Always start with a fully thawed pork roast; cooking from frozen in the slow cooker can keep the meat in the temperature “danger zone” too long. Use a meat thermometer to ensure the pork reaches at least 145°F in the center, though for tenderness this roast is best cooked until it reaches 190-200°F and shreds easily. Refrigerate leftovers within 2 hours in shallow containers.
Variations
Garlic Pork Roast: Rub the pork roast with 1 teaspoon of garlic powder before adding the soup mixture. The garlic mellows during cooking and adds savory depth.
Cream of Chicken Version: Swap the cream of mushroom soup for cream of chicken or cream of celery soup. Each will give the gravy a slightly different but still comforting flavor.
Onion and Carrot Pork Roast: Scatter 1 sliced onion or 1 cup of baby carrots around the roast before adding the soup mixture. The vegetables become tender and sweet during cooking, adding flavor to the gravy.
Herbed Pork Roast: Add 2 bay leaves, 1 teaspoon of dried thyme, or 1 teaspoon of dried rosemary to the slow cooker. Remove bay leaves before serving.
Pepper Pork Roast: Add 1 teaspoon of black pepper or ½ teaspoon of red pepper flakes to the soup mixture for a little heat.
Creamy Mushroom Pork Roast: Add 8 ounces of sliced mushrooms to the slow cooker along with the pork. The mushrooms add earthiness and soak up the gravy.
Serving Suggestions
This pork roast is all about the gravy, so serve it over something that can soak it up:
-
Mashed potatoes (the classic choice)
-
Buttered egg noodles
-
White rice or brown rice
-
Creamy polenta
-
Crusty bread or biscuits
For a complete meal, add:
-
Roasted carrots or green beans
-
Steamed broccoli or asparagus
-
A simple green salad with a tangy vinaigrette
-
Coleslaw for freshness and crunch
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 5 days. The gravy will thicken as it cools, and the flavors will continue to meld.
To reheat, place individual portions in the microwave in 60-second bursts, or warm the entire dish in a covered skillet over medium-low heat, adding a splash of water or broth if the gravy has thickened too much.
This dish freezes well for up to 3 months. Cool completely, then transfer to freezer-safe containers. Thaw overnight in the refrigerator before reheating.
Why This Recipe Works
The combination of cream of mushroom soup and dry onion soup mix is the secret to this dish’s rich, savory gravy. The cream of mushroom soup provides body, creaminess, and umami depth. The dry onion soup mix adds concentrated onion flavor, salt, and other seasonings that would otherwise require a dozen different spices.
No additional liquid is needed because the pork releases moisture as it cooks. The long, slow cooking time allows the collagen in the pork shoulder to break down, turning tough, chewy meat into fork-tender perfection. The meat’s natural juices combine with the condensed soup to create a thick, flavorful gravy.
This recipe is proof that you do not need a long list of ingredients or complicated techniques to make a deeply satisfying meal. With three simple ingredients and a slow cooker, you can create a pork roast that is tender, savory, and delicious. Perfect for Father’s Day, Sunday supper, or any time you need a warm, no-fuss dinner that tastes like home.
