Our Best Bites Grill Guide Meta_edited-2Okay, now let’s talk about today’s recipe because it’s a good one!

Tri Tip Roast

When people think about a beef roast, it’s often a giant pot roast or prime rib that takes hours too cook and feeds an army with all the fixings.  While that’s nice sometimes, the majority of the time I just want a quick and easy roast to feed my little family on a weeknight.  Enter, the Tri Tip Roast.  If you like tri-tip steak, you’ll love this roast because it’s the same cut of meat (just not cut into individual steaks.)  Reasons to love Tri-Tip:
– it’s generally a pretty affordable cut
– it’s naturally a reasonable size, at 1.5-2lbs
– it works beautifully with any marinade or spice rub
– it cooks in just over 30 minutes
– it’s a lean cut, with lower fat that other roasts, yet still really tender and flavorful

Garlic Rosemary TriTip Roast

Have I convinced you yet?  This is one of my go-to meals on Sundays, with one of my favorite marinades during the summer when my rosemary is going crazy!  I combine a little olive oil (I’m using our Rosemary Extra Virgin Olive Oil, which is awesome, here), a little Dijon mustard, Worcestershire sauce, lots of garlic, and some fresh rosemary.

Smother that tri tip with the marinade and let it rest in the fridge for a while.

Pop it in the oven and before long, your house will smell amazing and people will come running for dinner before you even tell them it’s time for dinner.

Since tri-tip is a leaner cut, you’ll want to make sure to not cook it past medium, and medium-rare is optimal.  Definitely use a thermometer so you can get it perfect every time.  A Thermapen is my absolute favorite, and well worth the price tag. 


 When it comes to meat, you really don’t want to play the guessing game.  Just use a quality thermometer and cook it exactly to temperature every time!

This roast is so flavorful and delicious, with all my favorite flavors.  You can also use any pan juices to drizzle over the top, just see my notes in the recipe about that.

  1. It looks yummy! Can you do this in the Instant Pot? If so, what would you have to alter? I just got an Instant Pot and I’m excited to start using it.

    1. Hi Michelle! Just click on our front page and you’ll see the icon that says “get 7 free recipes!” You’ll sign up for our newsletter right there!

  2. This looks yummy!! I’m having trouble finding this cut of meat. Where do you buy yours? Does it go by any other name? Can’t wait to try it!

    1. Costco has them 2 in a package for about $25. The roast looks like a triangle thus the name tri-tip.

    2. People here say it’s popular on the west coast (that’s where I live now) but I remember having tri tip when I lived in the Chicago “burbs”! It’s everywhere out here but you may have to go to a “specialty butcher shop” to find it where u live!

    3. It popular in California but I had it for the first time in the “burbs” of Chicago! U may have to go to a specially butcher shop where u live to find it! Good luck

    4. If you’re on the east coast they are difficult to find. Omaha steaks sells them and a stand alone butcher will cUT one for you. It’s funny though in CA they sell this in sandwiches on the road side

  3. We’re having this tomorrow and I’m super excited. And my husband loves when he gets a meat and potatoes meal!

  4. I had never heard of tri tip until I moved to California from the east coast. Seems it’s still hard to get when you live east of the Rockies! I have only recently learned that the cut goes by another name. If you don’t see “tri tip” or “Santa Maria cut”, find a good butcher shop and ask for “Butcher’s Cut”.

  5. Hi, does this have to sit for that long? Would just a couple hours be okay? Also if I only have dried rosemary on hand will that work?

  6. We made this last night and it turned out perfectly. I marinated for about 8 hours and took it out at 30 minutes to rest and even though I didn’t have a thermometer to test it, it was perfectly medium rare! We loved it and wonder if searing it before the oven might make it even better??

  7. Looks delicious! I’m trying this out tonight. I just recently started experimenting with this cut of meat and I love it! It’s a more forgiving piece of meat if you kind of messed up (which
    I have). I find it to be tender (when not burnt😜)and flavorful. I usually marinate my over night. I have lived in CA all my life and wish I would have tried cooking with this cut of meat sooner.

  8. This is a great recipe. The only thing I did different was smoke it on the grill. I used pecan wood. I seared it on both sides then put it on the cooler side if the grill. That lightly smoked flavor was perfect with this marinade.

  9. Made this tonight for the family. YUM!!! Baked to 131 degrees and tented for 15 minutes. Perfect. Will definitely make this again!

  10. Hello Sarah
    I just read, well reread, your article on Garlc -Rosemary Tri Tip Roast.
    While checking out the finished roast, I couldn’t help but notice it appears the roast may have been sliced improperly.
    Tri tip should always be sliced against the grain, and since tip grains run in 3 separate directions it and be tricky to slice.

    1. I’m going to try your marinade recipe and Sous Vide the roast at 131.5 degrees for 5 to 6 hours then finish it with a quick sear on my Weber bbq pit.
