There is something especially fitting about a slow cooker roast on Labor Day, when summer starts giving way to cooler evenings and folks are ready for one more comforting family meal before the season turns. This 4-ingredient version keeps things simple, letting sliced rump roast turn tender and full of deep, beefy flavor with hardly any fuss at all. It is the kind of dependable supper that feels right at home in a Midwestern kitchen, where a good roast has long been a way to feed a table full of hungry people well.
Serve this roast with mashed potatoes, buttered egg noodles, or a scoop of creamy polenta to catch every bit of that rich sauce. A side of green beans, sweet corn, or roasted carrots rounds it out nicely, and if you are feeding a holiday crowd, a basket of warm rolls and a crisp salad make it feel company-worthy without adding much extra work.
4-Ingredient Slow Cooker Labor Day Roast using Sliced Rump Roast
Servings: 6
Ingredients
3 to 3 1/2 pounds sliced rump roast
1 packet dry onion soup mix
1 can condensed cream of mushroom soup
1 cup burgundy wine
Directions
1. Lightly coat the inside of a white oval slow cooker with cooking spray or a thin swipe of oil if desired for easier cleanup.
2. Lay the sliced rump roast in the slow cooker, overlapping the pieces slightly so they cook evenly and stay nestled in the sauce.
3. In a medium bowl, stir together the dry onion soup mix, condensed cream of mushroom soup, and burgundy wine until smooth.
4. Pour the sauce mixture evenly over the beef, making sure the slices are well covered.
5. 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 easily pulls apart with a fork.
6. Gently spoon some of the sauce over the roast before serving, and serve hot with your favorite sides.
Variations & Tips
Make it heartier: Add halved baby potatoes, thick carrot chunks, or pearl onions to the slow cooker under the beef so they soak up the juices as everything cooks.
For a deeper sauce: If you want the gravy a little richer, remove the cooked beef, then simmer the sauce on the stovetop for a few minutes until it reduces slightly and thickens.
No burgundy on hand: A beef broth substitute works just fine if you prefer not to cook with wine, though the final flavor will be a little milder and less layered.
Best cut advice: Sliced rump roast works beautifully here because it cooks down faster than a whole roast and gives you more seasoned edges in every serving. Keep the slices fairly even so they become tender at the same rate.
Leftover idea: Tuck the extra roast and sauce into toasted sandwich rolls the next day, or spoon it over egg noodles for an easy second supper that feels every bit as comforting as the first.
