There are days when you need dinner to be simple. No complicated techniques, no long lists of ingredients, no standing over a hot stove. This 3-Ingredient Slow Cooker Pork Loin Supper is exactly what those days call for. With just pork, cream of mushroom soup, and dry onion soup mix, you can create a rich, creamy, deeply savory meal that tastes like you spent hours in the kitchen.
The beauty of this recipe is in its simplicity. Cubed pork loin cooks low and slow in a mixture of condensed cream of mushroom soup and dry onion soup mix. No additional liquid is needed—the pork releases its own juices as it cooks, creating a thick, flavorful gravy that coats every bite. The result is tender, juicy pork in a savory mushroom-onion sauce that begs to be spooned over mashed potatoes, rice, or egg noodles.
This is the kind of recipe that saves busy weeknights, impresses unexpected guests, and makes you look like a kitchen hero with almost no effort. It is perfect for beginners, for nights when you forgot to plan dinner, or any time you need a warm, comforting meal without a lot of fuss.

3-Ingredient Slow Cooker Pork Loin Supper
Prep Time: 10 minutes | Cook Time: 6-8 hours on LOW or 3-4 hours on HIGH | Total Time: Approximately 6-8 hours
Yield: 4 servings
Ingredients
-
2 pounds raw pork loin, cut into 1-inch cubes
-
2 (10.5-ounce) cans condensed cream of mushroom soup
-
1 (1-ounce) packet dry onion soup mix
Instructions
1. Prepare the Slow Cooker:
Place the raw cubed pork loin in an even layer on the bottom of a 4- to 6-quart slow cooker, making sure the meat is spread out so it cooks evenly.
2. Make the Sauce:
In a medium bowl, stir together the condensed cream of mushroom soup and the dry onion soup mix until well combined. The mixture will be thick, but that is what will turn into a rich gravy as it cooks.
3. Coat the Pork:
Pour the soup mixture evenly over the pork cubes, using a spatula to spread it so all the meat is coated. Do not add extra water; the pork will release enough juices as it cooks.
4. Cook:
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 pierced with a fork.
5. Serve:
Serve the pork and gravy hot over mashed potatoes, rice, or egg noodles.
Recipe Notes & Pro Tips
Pork Loin vs. Pork Shoulder: Pork loin is a lean cut that can become dry if overcooked. This recipe works best when cooked on LOW for 6-8 hours, which keeps the meat moist and tender. If using pork shoulder (pork butt), increase the cooking time to 8-10 hours on LOW. Pork shoulder has more fat and connective tissue, making it even more tender.
Cut the Pork into Uniform Cubes: Cutting the pork into 1-inch cubes ensures even cooking. Cubes that are too large may not become tender; cubes that are too small may become dry.
Do Not Add Extra Liquid: This recipe does not require any additional water or broth. The pork releases juices as it cooks, which thins the condensed soup into a perfect gravy. Adding extra liquid will result in a thin, watery sauce.
Thicken the Gravy: If the gravy is thinner than you would like after cooking, remove the pork and whisk in a slurry made from 1 tablespoon of cornstarch mixed with 2 tablespoons of cold water. Turn the slow cooker to HIGH and cook, uncovered, for 15-20 minutes until thickened, then return the pork to the slow cooker.
Add Vegetables (Optional): For a more complete meal, add 2 cups of baby carrots, 1 cup of sliced mushrooms, or 1 cup of frozen peas during the last hour of cooking. The vegetables will absorb the gravy and add flavor.
Cream of Mushroom Substitutions: Cream of chicken soup or cream of celery soup can be substituted for the cream of mushroom. Each will create a slightly different flavor profile but will work just as well.
Variations
Garlic Pork Loin Supper: Add 1 tablespoon of garlic powder or 6 cloves of fresh minced garlic to the soup mixture. The garlic mellows during cooking and adds savory depth.
Herbed Pork Loin Supper: Add 1 teaspoon of dried thyme, 1 teaspoon of dried rosemary, or 2 bay leaves to the slow cooker. Remove bay leaves before serving.
Mushroom Pork Loin Supper: Add 8 ounces of sliced cremini or button mushrooms along with the pork. The mushrooms add earthiness and soak up the gravy.
Creamy Pork Loin Supper: Stir in ½ cup of sour cream or heavy cream during the last 30 minutes of cooking. The cream adds richness and a slightly tangy finish.
Onion Pork Loin Supper: Add 1 large yellow onion, thinly sliced, along with the pork. The onion becomes soft and sweet, adding texture and flavor.
Spicy Pork Loin Supper: Add ½ teaspoon of red pepper flakes or 1 teaspoon of Cajun seasoning to the soup mixture. For extra heat, add 2 chopped chipotle peppers in adobo sauce.
Serving Suggestions
This creamy pork and gravy is all about the sauce, 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:
-
Steamed green beans or broccoli
-
Roasted asparagus or Brussels sprouts
-
A simple green salad with a tangy vinaigrette
-
Sautéed spinach with garlic
A sprinkle of fresh parsley adds color and freshness.
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, warm gently in a covered saucepan over medium-low heat, stirring occasionally. Add a splash of milk or broth if the gravy has thickened too much. You can also reheat individual portions in the microwave in 60-second bursts.
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. Together, they create a sauce that is far more complex than the sum of its parts.
No additional liquid is needed because the pork releases moisture as it cooks. The long, slow cooking time allows the meat to become tender while the sauce thickens naturally. The pork loin, though lean, stays moist because it is cooked in the creamy gravy rather than in direct heat.
This recipe is proof that you do not need a long list of ingredients or complicated techniques to make a delicious, satisfying meal. With three simple ingredients and a slow cooker, you can create a pork supper that is rich, creamy, and deeply comforting. It is weeknight cooking at its best: simple, reliable, and delicious. Perfect for busy nights, lazy Sundays, or any time you need a warm, hearty meal without a lot of fuss.
