How to Make Crockpot Beef Sirloin Tip Roast
Step 1: Season the Beef
Pat the sirloin tip roast dry with paper towels.
This helps the seasoning stick and gives you a better sear.
Combine the salt, pepper, garlic powder, onion powder, thyme, and rosemary.
Rub the seasoning mixture all over the roast.
Don't be shy with it!
This is a large piece of meat, so you want plenty of seasoning on the exterior.
Step 2: Sear the Roast
Heat the olive oil in a large skillet over medium-high heat.
Once hot, carefully place the roast in the pan.
Sear it for about 2–3 minutes per side, turning until the outside is nicely browned.
You aren't trying to cook the roast through.
You're simply developing that beautiful browned exterior and adding another layer of flavor.
And yes, you can technically skip this step if you're in a hurry.
But if you have an extra few minutes, I highly recommend the sear.
It makes a noticeable difference in the finished dish.
Step 3: Prepare the Crockpot
Place the sliced onion, carrots, and potatoes in the bottom of the slow cooker.
Add the minced garlic.
Place the browned roast on top of the vegetables.
Step 4: Make the Cooking Liquid
In a bowl, whisk together the beef broth, Worcestershire sauce, and tomato paste.
Pour the mixture around the roast.
You don't need to completely submerge the beef.
The slow cooker will create plenty of moisture as everything cooks.
Step 5: Cook Low and Slow
Cover the slow cooker.
Cook on LOW for approximately 6–8 hours, depending on the size and shape of your roast and your desired texture.
You can also cook it on HIGH for approximately 3½–4½ hours, although the lower setting is generally preferable when you're aiming for tender meat.
Start checking the roast toward the earlier end of the cooking window rather than automatically leaving it for the maximum time.
Step 6: Check the Beef
Use an instant-read thermometer to check the internal temperature.
For food safety, beef roasts should reach at least 145°F (63°C) followed by a rest.
For the softer, more well-done texture many people expect from slow-cooked roast beef, you may choose to cook it longer.
Keep in mind that sirloin tip is leaner than chuck, so cooking it indefinitely isn't necessarily better.
Step 7: Rest the Roast
Remove the roast from the slow cooker and place it on a cutting board.
Tent it loosely with foil.
Let it rest for about 10–15 minutes before slicing.
This gives the juices time to redistribute.
Step 8: Make the Gravy
Don't throw away those juices!
They're the best part.
Pour several cups of the cooking liquid into a saucepan or carefully separate the liquid from the vegetables.
In a small bowl, whisk the cornstarch with cold water until smooth.
Bring the cooking liquid to a gentle simmer and slowly whisk in the cornstarch slurry.
Cook for a few minutes, stirring constantly, until the gravy thickens.
Taste and adjust the seasoning if necessary.
How to Keep Sirloin Tip Roast Tender
This is the question I get most often with leaner beef roasts.
Don't Skip the Liquid
A flavorful cooking liquid helps create a moist environment inside the slow cooker.
Don't Overcook It Just Because It's a Slow Cooker
A common misconception is that slow-cooker beef can cook forever and only become more tender.
That's not always true.
Sirloin tip is relatively lean. Once it has reached the texture and doneness you want, continuing to cook it for many additional hours can eventually make the meat dry or stringy.
Slice Against the Grain
This little trick makes a huge difference.
Look closely at the direction of the muscle fibers.
Then slice across those fibers rather than parallel to them.
Shorter muscle fibers make the beef feel much more tender when you chew it.
What to Serve With Sirloin Tip Roast
You've already got potatoes and carrots cooking with the beef, but there's always room for a few extras!
Homemade Dinner Rolls
Soft rolls are perfect for soaking up that gravy.
Green Beans
A simple side of steamed or roasted green beans adds fresh color and texture.
Creamed Corn
For a classic comfort-food dinner, creamy corn makes a wonderful pairing.
Mashed Potatoes
Yes, even though this recipe already contains potatoes!
Serve the roast and gravy over a mound of mashed potatoes for the ultimate comfort-food plate.
Simple Green Salad
A crisp salad with a tangy vinaigrette can help balance the richness of the roast.
Easy Ingredient Substitutions
Can I Use Baby Carrots?
Absolutely.
They're convenient and require almost no preparation.
Can I Use Russet Potatoes?
Yes.
Cut them into large chunks so they don't completely fall apart during the long cooking time.
Can I Use Red Potatoes?
Definitely.
Red potatoes hold their shape nicely in slow-cooked dishes.
Can I Use Fresh Herbs?
Of course!
Fresh rosemary and thyme can provide even more flavor.
Use a smaller amount than you would dried herbs and add extra fresh herbs at the end if desired.
Can I Skip the Tomato Paste?
Yes.
It adds depth and helps round out the gravy, but the roast will still work without it.
Can You Add Mushrooms?
Absolutely!
Add sliced mushrooms during the final few hours of cooking if you prefer them firm, or add them earlier if you want them very soft.
Mushrooms pair especially well with the beef gravy.
Can You Add Red Wine?
Yes.
For a richer flavor, replace some of the beef broth with dry red wine.
A modest amount is enough—you don't want the wine to overpower the beef.
Slow Cooker vs. Oven
The slow cooker is convenient because it lets you walk away while dinner cooks.
The oven, however, gives you more control over browning and can produce a slightly different texture.
For busy days, the crockpot wins on convenience.
For a special Sunday dinner when you don't mind spending more time in the kitchen, an oven-roasted version can be wonderful too.
Make-Ahead Instructions
You can prepare the vegetables and seasoning mixture ahead of time.
You can also sear the beef earlier in the day and refrigerate it until you're ready to assemble the slow cooker.
For best food safety, keep raw or partially prepared meat properly refrigerated rather than leaving it at room temperature while you prepare other ingredients.
How to Store Leftovers
Allow leftovers to cool appropriately, then transfer the beef, vegetables, and gravy to airtight containers.
Refrigerate promptly.
For best quality, enjoy refrigerated leftovers within about 3–4 days.
When reheating, warm the beef gently with some gravy or broth to help prevent it from drying out.
Can You Freeze Beef Sirloin Tip Roast?
Yes.
Cooked beef and gravy can generally be frozen for longer-term storage.
Place cooled beef and gravy into freezer-safe containers or bags, remove excess air, and label with the date.
For best quality, use within approximately 2–3 months.
Thaw overnight in the refrigerator before reheating.
The potatoes may change texture slightly after freezing and thawing, but the beef and gravy should still make excellent leftovers.
Delicious Ways to Use Leftover Roast
Don't feel like eating the exact same dinner twice?
I don't blame you!
Turn those leftovers into something completely different.
Roast Beef Sandwiches
Pile thinly sliced beef onto toasted bread with horseradish sauce and melted cheese.
Beef Hash
Chop the leftover beef and potatoes and fry everything in a skillet until browned and crispy.
Top with a fried egg for an incredible breakfast.
Beef and Gravy Over Toast
Warm the leftover beef and gravy and spoon it over thick slices of toasted bread.
Simple, cozy, and very satisfying.
Beef Tacos
Shred the leftover beef and warm it with taco seasoning.
Add tortillas, cheese, lettuce, tomatoes, and salsa.
Suddenly, last night's roast has become tonight's taco dinner!
Frequently Asked Questions
Is sirloin tip roast good for the crockpot?
Yes, but because sirloin tip is relatively lean, it benefits from a flavorful cooking liquid and careful attention to cooking time.
Why is my sirloin tip roast tough?
It may need more cooking time if connective tissue hasn't softened yet, but overcooking can also make this relatively lean cut dry.
Check both the internal temperature and the actual texture rather than relying on time alone.
Should I sear the roast before putting it in the crockpot?
You don't absolutely have to, but searing creates additional browned flavor and is worth the few extra minutes.
Can I cook the roast on HIGH?
Yes.
However, LOW is generally the better choice when you want a gentle, slow cooking process.
Should the roast be completely covered with broth?
No.
You don't need to submerge the roast.
The slow cooker traps steam and moisture as it cooks.
How do I make the gravy thicker?
Use a cornstarch slurry made with cornstarch and cold water.
Add it gradually to hot cooking liquid while whisking.
Can I make this without potatoes?
Absolutely.
Leave them out and serve the roast with mashed potatoes, rice, noodles, or another favorite side.
