Juicy Oven Tri-Tip Roast - Tender and juicy tri-tip roast marinated overnight in a flavor packed tenderizing marinade then seared hot in a skillet and finished in the oven.

A delicious tri-tip roast recipe marinated in balsamic vinegar, red wine vinegar, onion, garlic and seasonings for a super tender and flavorful end result.

After marinating, the roast is seared in a cast iron skillet for a delicious crusty exterior and then finished in the oven to your preferred doneness. I personally like my roast cooked medium-rare which is how I cooked my roast (as seen in pics).

You can serve your roast with a wide variety of side dishes such as mashed or roasted potatoes, a fresh salad, roasted veggies, and more. I served my roast with bbq bacon baked beans, roasted rosemary garlic potatoes and Texas toast.

This tri-tip is also great sliced and served in tacos, burritos, as a sandwich, and more! I will link some of my favorite side dishes to serve with this recipe for you below.

How to make a juicy oven tri tip roast:

Add all marinade ingredients to a large bowl and whisk to combine.

Place your tri-tip in a large storage bag and pour marinade over the roast. Seal bag and gently shake bag around to fully coat the roast. Place in the fridge for at least 8 hours but ideally 24 hours. Flip bag over about halfway through to make sure the roast is evenly marinating.

Preheat oven to 400 degrees.

Heat a cast iron skillet to high heat. Once very hot, add oil and begin to sear the roast on all sides for about 2 minutes until there is a nice char.

Transfer skillet to the preheated oven and bake for 20-30 minutes depending on your preferred doneness. 130 degrees for rare, 140 degrees for medium-rare, 145 degrees for medium. You will need a meat thermometer to check the temperature.

Once done, remove from oven and let rest for 5-10 minutes. Slice and serve.

Beef Roast temperatures for preferred doneness:

• Rare: 125-130 degrees
• Medium-Rare: 135-140 degrees
• Medium: 140-145 degrees
• Medium-Well: 150-155 degrees
• Well Done: 155+ degrees
