This 4-ingredient slow cooker roast is the kind of dinner that makes a hectic back-to-school day feel a little more manageable. Thick-sliced sirloin tip roast turns surprisingly tender after a long, gentle cook, and the simple ingredient list keeps prep fast enough to handle before everyone rushes out the door. It has that classic Midwest comfort-food appeal too: hearty beef, rich juices, and a no-fuss method that lets the slow cooker do the heavy lifting while life keeps moving.
Serve this roast with mashed potatoes, buttered egg noodles, or roasted baby potatoes to soak up the savory juices. A simple green bean side, glazed carrots, or a crisp salad balances the richness nicely, and if you want to stretch leftovers, the beef is also great piled onto toasted rolls with provolone for easy sandwiches the next day.
4-Ingredient Slow Cooker Back-to-School Roast using Thick-Sliced Sirloin Tip Roast
Servings: 6
Ingredients
2 1/2 to 3 pounds thick-sliced sirloin tip roast
1 packet dry onion soup mix (about 1 ounce)
1 can condensed cream of mushroom soup (10.5 ounces)
1 cup low-sodium beef broth
Directions
1. Pat the thick-sliced sirloin tip roast dry and place it into the slow cooker.
2. In a medium bowl, whisk together the dry onion soup mix, cream of mushroom soup, and beef broth until smooth, then pour the mixture evenly over the roast.
3. Cover and cook on low for 7 to 8 hours or on high for 4 to 5 hours, until the beef is very tender and easy to cut with a fork.
4. Transfer the roast to a cutting board, let it rest for 10 minutes, then slice or shred and spoon some of the cooking juices over the top before serving.
Variations & Tips
Make It Gravy-Rich: If you like more sauce for potatoes or noodles, stir an extra 1/2 cup beef broth into the slow cooker at the beginning. For an even thicker finish, whisk 1 tablespoon cornstarch with 1 tablespoon cold water and stir it into the hot juices for the last 15 minutes.
Add Vegetables: Baby carrots, halved onions, or small potatoes can go right into the slow cooker around the roast. They make this feel even more like a complete one-pot dinner, which is especially helpful on busy school nights.
For Easier Slicing: Letting the roast rest before cutting really helps keep the slices neat and juicy. If the meat is extra tender and starts to fall apart, just lean into it and serve it shredded with plenty of juices spooned on top.
Meal Prep Tip: You can mix the soup, broth, and onion soup mix the night before and store it in the fridge. In the morning, all you need to do is place the roast in the slow cooker, pour the mixture over it, and turn it on before the day gets busy.
