Costco Beef Loin Tri Tip Roast Review

In our house we love a good barbecued tri-tip. When I spotted this try tip roast at Costco I immediately knew what was for dinner. Costco has a few different styles of tri tip steak.You can buy them pre-seasoned, or unseasoned. I smoked this unseasoned tri-tip and it was delicious.

Cooking the Tri Tip Roast

To cook the tri tip roast I decided to smoke it on the grill. I first heated the coals, and added some mesquite BBQ smoking chips.

I then seasoned the tri tip roast on both sides with McCormick Montreal Steak seasoning and placed it onto the grill off to the side of the coals and closed the lid to let smoke for 60-90 minutes.

Tri tips should be cooked until the internal temperature reaches a minimum of 145 degrees measured by a food thermometer with a three minute rest time. 

As a general rule it will normally take about 60 – 90 minutes to cook a tri tip roast. Depending on if you prefer your meat to be rare or more well done. 

I ended up smoking this one for about 90 minutes so that it was pretty well done. After 90 minutes I checked the inside coloring and temperature and it was just perfect.

After removing the tri tip from the grill I wrapped it in foil and let it rest for about 15 minutes. 

After letting it rest, it was ready to be served. When it was done cooking it looked and smelled delicious. 


We have tried many different tri tips, and the tri tip was very good. It had a rich beef flavor, a tender texture, and was not too chewy.

I only ended up cooking one of the tri tips from the package and put the other one in the freezer. 

Final Thoughts 

Tri tip is going to taste a bit different depending on how it is cooked, but overall I thought this tri tip was very good. I enjoyed the tri tip and would definitely recommend it.
