1. Add the Roast
Place the pork loin roast or beef chuck roast in the center of the slow cooker insert.
2. Add the Vegetables
Arrange the baby potatoes and baby carrots around the roast. Keeping the vegetables around the meat allows them to cook in the flavorful juices as the roast becomes tender.
3. Add the Creamy Sauce
Pour the condensed cream of mushroom soup directly over the roast. Sprinkle the dry onion soup mix evenly over the top.
The mushroom soup creates a creamy sauce while the onion soup mix adds savory onion flavor and seasoning without requiring a long list of spices.
4. Slow Cook
Cover the slow cooker and cook on LOW for 7–8 hours or HIGH for about 4 hours, until the meat is fully cooked and tender and the vegetables are soft.
Cooking times can vary depending on the size and shape of the roast and your slow cooker, so check for doneness before serving.
5. Serve
Carefully transfer the roast to a serving platter. Spoon some of the creamy mushroom gravy over the meat and serve with the tender potatoes and carrots.
Helpful Tips
Choose your roast carefully: Beef chuck roast is naturally well suited to long, slow cooking because its connective tissue breaks down over time, creating very tender meat. Pork loin is considerably leaner, so it can become dry if cooked longer than necessary.
Keep the potatoes large: Baby potatoes can be left whole if they are small, or halved if they are larger. This helps them hold their shape during the long cooking time.
Don’t add extra salt too quickly: Onion soup mix and condensed mushroom soup are already seasoned, so taste the gravy before adding additional salt.
For pork: If using pork loin, check the internal temperature rather than relying only on the cooking time. USDA guidance recommends cooking whole cuts of pork to at least 145°F (63°C), followed by a short rest.
For beef chuck: If using chuck roast, cooking until it is fork-tender is more important than simply reaching a minimum temperature. Chuck generally benefits from the longer cooking time needed to soften its connective tissue.
What to Serve With This Roast
This meal already includes potatoes and carrots, making it a complete dinner on its own. For an extra comforting meal, serve it with:
- Warm dinner rolls
- Crusty French bread
- Steamed green beans
- A simple green salad
- Buttered egg noodles
The creamy mushroom gravy is especially delicious spooned over the potatoes.
Leftovers
Store leftover meat and vegetables in an airtight container in the refrigerator and use within a few days. Reheat gently with some of the leftover gravy to help keep the meat moist.
Leftover beef can also be shredded and served in sandwiches, while leftover pork can be sliced and added to wraps, rice bowls, or reheated with the vegetables for an easy second meal.
