Slow Cooker Sirloin Tip Roast

We cooked a Crockpot sirloin tip roast with carrots, potatoes and gravy the other night and it turned out delicious! Super fork tender and moist, the Sirloin Tip Roast soaked up the flavors as it cooked and was really easy to throw together.

This recipe is a complete one pot meal with a thick onion soup mix gravy and vegetables that all cook to tender and delicious all day while you’re gone. My kids ask for this all the time now and I am happy to add it to our long list of easy Crockpot recipes now.

Isn’t it great to cook all the things together at the same time? That means when it is done you don’t have to bake, air fry, to cook anything beyond that. Just serve it up on a plate and you’re set to eat together. Of course you can do this by making a slow cooker beef stew but sometimes you want to cook a larger hunk of meat.

When it is cold outside I am all about comfort foods like this. If we happen to have leftovers they save quite well also with brown gravy over the top which is a win win.

Should you cook beef in Crockpot on low or high?

As you know low and slow is key when you’re cooking thick hunks of meat like this one. Gives it enough time to break down those connective tissues that make it chewy if it isn’t cooked long enough. In the oven it would work, but it’s better in a Crockpot. Second best would be our fast sirloin tip roast Instant Pot my friends!

Reason being is with the lid on it literally steams hour after hour until it falls apart just with a fork when done. Now cook times will vary depending on it’s size, and if you want slow cooker shredded beef or to slice it.

Ingredient Notes

For the timing below you are going to want to pick up a fresh or thawed sirloin tip roast. This looks a bit like a point cut corned beef piece and should be available readily in the meat department of your grocery store.

1 package of dry onion soup mix is an easy way to add a pop of flavor since the minced onions and seasonings are already mixed in this dry mix.

You will need liquid. Of course water is an option but that won’t enhance the flavor at all so I generally choose Red wine vinegar with beef broth for a pop of flavor.

And to add flavor I will add a dash of Worcestershire sauce and I love to add some diced garlic or use roasted air fryer garlic if I have some fresh into this

What kind of vegetables can you add?

Large chunks of carrots and potatoes are the best choices. You can really load up on the vegetables if you want to on this one. Add a sliced onion if you want, whole green beans would work too. They need to be of the firmer variety so they don’t turn to mush though.

How to Make the Gravy

Then you’ll need heavy cream and cornstarch to thicken the liquid in your pot at the end to transform it into gravy. In the time that your meat is resting you can whisk in thickener to make the drippings creamy which will make your meal even more melt-in-your-mouth tender.

Frozen Sirloin Tip Roast in Crockpot

If yours isn’t thawed, follow our slow cooker frozen roast recipe instead or for a faster result you can refer to our frozen roast in Instant Pot directions that is done in a fraction of the time you see here.

Should you brown roast before slow cooking?

Yes, you’ll want a pan to sear the outside first and get it browned. This does two things: it will add a bit of texture to the outside but mostly it will keep the moisture as much as possible inside the meat instead of leaching out into the pot. I suggest this step with all of our easy slow cooker recipes but it will work if you forget (just won’t be as moist).

Does sirloin roast get tougher the longer you cook it?

Sirloin is leaner than other cuts like chuck, meaning it has less fat. Because of this it requires less time or yes it will dry out. In order to avoid this set to the designated cook time listed below and check after hour 5 or 6. Once the middle reaches 135-140 degrees F turn pot off and allow to rest inside for 15 minutes.

Tips for Success

Unlike our smoked sirloin tip roast the outsides will remain soft with this cooking method unless you stuck it into the oven under broil for a few minutes at the end. This isn’t a necessity but an option if texture is big for you. Or if you are cooking a Ninja Foodi roast you can crisp the outside a bit at the end with the lid that is attached.

When choosing vegetables to add into the pot you want them to be firm, like potatoes and carrots will cook at the same rate and won’t break down as much as let’s say broccoli would. Don’t forget to allow the meat to rest too or the juices will release too quickly making it more dry.

If someone in your house prefers for the veggies and protein be cooked separately you will still need to add all of the liquid requirements but then you can go on to make a batch of crockpot carrots on the side instead. That works too and I get it, my husband sometimes is the same way.

How to save leftovers

Pot roasts save quite well so don’t throw any of it away. Make sure you don’t discard the sauce because you’ll want to combine the two so it stays moist. Store in a container with a lid covered in gravy. Reheat within 3 days after in the microwave for about 2 minutes and enjoy.
