Tri tip in the oven is an easy, reliable way to get a juicy, flavorful roast with minimal effort. A quick marinade and a few pantry staples builds deep, savory flavor while the high-heat roast locks in moisture and creates a flavorful crust.
Tri tip is also known as a California cut, triangular sirloin, or culotte roast, and this simple method makes sure it stays tender and ready for slicing.
If you’re looking for other ways to cook tri tip, I also have a smoky, flavorful grilled Santa Maria tri tip, a quick and easy Instant Pot tri tip, and a slow-and-low slow cooker tri tip. No matter how you cook it, this cut delivers big flavor with minimal effort.
And if you love a good oven method, don’t miss my ribeye steak in the oven. It’s just as simple and just as impressive.
Why This Oven Tri Tip Recipe Works
Hands-off cooking: Let the oven do the heavy lifting—no flipping, no fussing, no standing guard with a meat thermometer every five minutes.
Big flavor, simple ingredients: Balsamic vinegar, soy sauce, and a few pantry staples team up to make beef that actually tastes like something.
Perfect for slicing: This method gives you juicy, tender meat that’s easy to slice thin (and harder to mess up).
Flexible marinade: Swap in your favorite flavors. This base plays just as well with smoky, spicy, or sweet tweaks if you want to mix it up.
Recipe Tips
The marinade time: A couple of hours in the marinade really helps the flavor soak in.
Use a meat thermometer: A thermometer takes all the drama out of roasting and keeps you from overcooking it. (If you want absolutely perfect doneness every time, try my sous vide tri tip, it’s basically foolproof.)
Let it rest: Giving the roast 15 minutes under foil locks in the juices and finishes the cooking without drying it out.
Slice against the grain: If you’re not sure where the grain runs, take a close look before you start cutting. Slicing the wrong way can turn tender meat into something chewy.
Pat it dry before roasting: Letting the excess marinade drip off helps the meat sear better and form a crust in the oven.
Don’t overcook it: Tri tip is at its best when it’s still a little pink in the middle. Going past medium takes you into “why is this so dry?” territory.
Adjust the marinade to your taste: Love a smokier flavor? Add a little smoked paprika or swap in a smoky barbecue sauce for part of the soy sauce.
Storing Leftovers
- Refrigerate: Let the roast cool completely, then transfer to an airtight container. Store in the fridge for up to 3 days.
- Freeze: Wrap individual portions tightly in plastic wrap, then stash them in a freezer safe container. They’ll keep for up to 3 months. Pro tip: freeze with a bit of the leftover pan juices if you have any.
- Reheat: For best results, reheat covered in the oven at 300°F with a splash of broth or water to keep it moist. Microwave works too, but use short bursts at 50% power. You’re reheating, not incinerating.
Frequently Asked Questions
For medium-rare, pull the tri tip out of the oven when it hits 135°F. For medium, aim for 145°F. Keep in mind the roast will rise about 10 degrees while it rests, so don’t wait too long to take it out.
Nope. Roast it uncovered to let the heat create a crust on the outside. Covering it would trap steam and prevent the meat from browning properly.
Tri tip has two different grain directions. Before cooking, take a good look at the meat so you can see where the lines run. After roasting, slice thinly against the grain for the most tender slices.
Yes! You can marinate it overnight if you want deeper flavor. Just don’t push it much longer than 24 hours or the acids in the marinade can start to break down the meat too much. If you want a different twist, try using my Japanese style marinade for a lighter, umami-packed flavor

How to Cook a Tri-Tip Roast in the Oven
If you make this recipe, please leave a star rating and comment.
Ingredients
- 2 pound Tri-tip beef roast
- ¼ cup olive oil
- 2 to 3 garlic cloves, minced
- ¼ cup balsamic vinegar
- ¼ cup Worcestershire sauce
- ¼ cup soy sauce
- 2 teaspoons Dijon mustard
- Salt and pepper
Instructions
- Place the tri-tip roast into a closable plastic bag and set aside.
- Whisk the marinade ingredients together in a small dish and pour into the bag with the roast. Press the excess air out of the bag, zip it closed. Massage the meat well, turning within the bag to coat completely with the marinade. Place in the refrigerator for 2 to 3 hours.
- Preheat the oven to 425°F, set a wire rack over a baking sheet.
- Remove the marinating roast from the plastic bag, letting excess marinade drip off. Place the roast on the wire rack and insert a thermometer probe into the center of the meat. Grind black pepper over the top.
- Transfer the baking sheet to the oven and roast for 30 to 35 minutes or until desired doneness. For medium-rare 135°F, for medium 145°F. Remove from the oven, cover with aluminum foil and rest for 15 minutes.
- Transfer to a cutting board and slice across the grain in thin slices. Place on a platter and serve.

Notes
- This cut of meat is also called a triangular sirloin roast or a California Cut.
- Use your favorite beef marinade or smoky rub to enhance the flavor. A spicy chipotle or my tri tip rub work well.
- Resting the roast for 15-minutes will increase the internal temperature by approximately 10-degrees.

any thought on if this would work in convection oven with multiple Tri Tips?
If you are using a convection oven, reduce the temperature to 400°F. If you have more than one tri-tip, you can cook them at the same time. Check the internal temperature on the smallest roast and remove that one from the oven first. As a general rule, it will take about the same amount of time in a convection oven if you reduce the temperature by 25°F. Extra roasts in the oven shouldn’t affect the time unless the oven is over-crowded. Your best bet is to use an internal meat thermometer which will take all the guesswork out of it.
how long to bake for medium well done after first 35 minutes of getting the crusty top done on a burgundy seasoned tri tip at 3.15 lbs???
i don’t have a thermomitor.
It should take another 5 to 10 minutes.
Best tri tip roast! Hands down. Made this last Wednesday and my 16-year-old daughter easily ate ½ pound, or more. Here it is Sunday evening and another roast is marinating as I type….
Woohoo! So happy this was a dinner-feast! Thanks for the great review, Tommy ?
Can you marinade this overnight?
Hi, Trisha…Yes, I think that would be lovely! Enjoy
This is a GREAT recipe. Best tri-tip I ever made! I didn’t have time to marinate, but I mixed the marinade and brushed it on both sides of the roast and let it sit for 1)2 hr before roasting. It was so tender and flavorful! Family loved it! I can’t wait to to make it again! THANK YOU!
Thanks for the great review, Gloria….My heart is so happy to hear it was a success for you and your family!❤️
I am a 75 yo male. Every attempt I make at cooking is an experiment. I check out the recipes, then I give it a try with a twist.
TRi-Tip roast 2.5 lb. oven roast .If you’re pressed for time, brush both sides with liquid smoke, flavor both sides with Montreal steak seasoning. Place on small grill
rack on baking pan. cover with foil. preheat oven to 250 deg. Bake two hrs. Turn half way thru and remove foil. when meat thermometer reaches 130 deg. remove from oven, turn broiler on hi and finish off roast 3 min. per side. Should be about medium. Remove from oven, let sit 15 min.
slice against the grain ‘ Serve with baked potato, corn and whatever your choice. ENJOY! Always a good idea to check your oven temp. with an oven thermometer as ovens are often off by as much as 20 degrees’
