This kind of slow cooker supper is exactly why a short ingredient list can still deliver deep, comforting flavor. Cubed sirloin tip roast turns tender as it simmers low and slow in rich gravy, creating a hearty Sunday-style beef dish that feels like it took far more effort than it actually does. It’s a practical Midwestern sort of meal—economical, filling, and ideal for busy days when you still want the house to smell like something special is cooking.
Serve these beef tips over mashed potatoes, buttered egg noodles, or fluffy white rice so none of that gravy goes to waste. A simple green bean side, roasted carrots, or a crisp salad adds balance, and warm biscuits or crusty bread are always welcome at the table for soaking up the extra sauce.
3-Ingredient Slow Cooker Sunday Gravy Beef Tips using Cubed Sirloin Tip Roast
Servings: 6
Ingredients
2 1/2 to 3 pounds cubed sirloin tip roast
2 packets brown gravy mix, about 0.87 to 1 ounce each
2 cans condensed cream of mushroom soup, 10.5 ounces each
Directions
1. Lightly coat the inside of your slow cooker with nonstick spray if desired for easier cleanup. Add the cubed sirloin tip roast to the slow cooker and spread it into an even layer.
2. In a medium bowl, whisk together the brown gravy mix and condensed cream of mushroom soup until smooth and well combined. Spoon the mixture over the beef, then stir to coat all the pieces evenly.
3. Cover and cook on low for 7 to 8 hours or on high for 4 to 5 hours, until the beef is fork-tender and the gravy is hot, thick, and silky. Give it a good stir once or twice during cooking if you’re home, but it will still turn out well if left alone.
4. Taste and serve hot over mashed potatoes, noodles, or rice, spooning plenty of gravy over each portion.
Variations & Tips
Make it oniony: Add 1 packet of onion soup mix along with the gravy mix for a deeper savory flavor. If you do this, taste before adding any extra salt, since packaged mixes can be quite seasoned.
For a thinner gravy: Stir in 1/2 to 1 cup of beef broth during the last hour of cooking if you prefer more sauce for spooning over noodles or rice. This is especially helpful if your slow cooker runs hot and reduces liquids more quickly.
Add mushrooms: Fresh sliced mushrooms can be added for more texture and an earthier flavor that works naturally with the soup base. Scatter them over the beef before cooking so they soften into the gravy.
Best cut note: Cubed sirloin tip roast works well here because the slow, moist heat gives it time to become tender. If your cubes are especially large, cut them into even bite-size pieces so they cook at the same rate.
Make-ahead tip: You can combine the beef, gravy mix, and soup in the slow cooker insert the night before, cover, and refrigerate. The next day, place the insert in the cooker and start cooking, adding a little extra time if everything is very cold.
