- Add the Roast
Place the sirloin tip roast directly into the slow cooker.
There is no need to brown the meat first, which keeps this recipe truly dump-and-go.
- Add the Onion
Scatter the sliced onion around and over the roast.
The onion will soften during cooking and add extra flavor to the gravy.
- Make the Gravy
In a bowl, whisk together the cream of mushroom soup, beef broth, Worcestershire sauce, and dry onion soup mix.
Pour the mixture over the roast.
- Slow Cook
Cover the slow cooker and cook on:
- LOW for 7–8 hours, or
- HIGH for 4–5 hours
The exact cooking time will depend on the size and shape of the roast and your slow cooker.
For the most tender result, cook until the roast is easily pierced with a fork.
- Rest and Slice
Carefully remove the roast and place it on a cutting board.
Let it rest for about 10–15 minutes, then slice it against the grain.
Spoon the rich onion gravy over the slices before serving.
Helpful Tips
Don’t Add Extra Salt Too Quickly
The onion soup mix and cream soup already contain salt. Taste the finished gravy before adding additional seasoning.
Slice Against the Grain
Sirloin tip is a relatively lean cut. Cutting the finished roast against the grain helps make each slice more tender and easier to chew.
Want Thicker Gravy?
If the gravy is thinner than you prefer, transfer it to a saucepan after cooking.
Mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir it into the gravy, and simmer until thickened.
Let the Roast Rest
Resting the meat before slicing gives the juices time to redistribute and makes slicing easier.
Serving Suggestions
This vintage-style roast is especially delicious served with:
- Creamy mashed potatoes
- Buttered egg noodles
- Roasted potatoes
- Green beans
- Glazed carrots
- Corn
- Peas
- Dinner rolls
- Simple garden salad
For a classic comfort-food plate, pile mashed potatoes onto the plate, add sliced beef, and pour the warm onion gravy over everything.
Storage
Store leftover beef and gravy in an airtight container in the refrigerator for 3–4 days.
For longer storage, freeze the beef with some of the gravy for up to 2–3 months.
Thaw frozen leftovers in the refrigerator before reheating.
Reheating Instructions
Place sliced beef and gravy in a covered skillet over low heat. Add a small splash of beef broth if necessary.
Warm gently until heated through.
You can also microwave individual portions in short intervals, keeping the beef covered with gravy to help prevent it from drying out.
Frequently Asked Questions
Do I have to sear the sirloin tip first?
No. This recipe is designed as a dump-and-go slow cooker recipe, so the roast goes directly into the Crockpot without browning.
Is sirloin tip roast tender in the slow cooker?
It can become tender when cooked slowly, but it is leaner than cuts such as chuck roast. Avoid relying solely on a fixed cooking time; check the roast for tenderness as it approaches the end of cooking.
Can I use another beef roast?
Yes. Chuck roast is a good alternative, although it contains more fat and connective tissue and will produce a different texture.
Can I add potatoes and carrots?
Yes. Cut potatoes and carrots into large, evenly sized pieces and place them around the roast. This turns the recipe into an easy one-pot meal.
Can I make the gravy without cream of mushroom soup?
You can substitute another condensed cream soup, such as cream of celery. The flavor will change slightly, but the gravy will still be rich and savory.
