Why This Recipe Works

After years of preparing tri-tip on the grill, last Father's Day, I learned that oven-tri-tip may just be even better!

There I was, trying to prepare a delicious Father's Day dinner, only to realize we were out of propane! When you live out in the middle of nowhere, you always have to have a plan B. In this case, it meant cooking the tri-tip in the oven.

Using my own Santa Maria Rub and a simple baste consisting of avocado oil, red wine vinegar, and freshly crushed garlic, yielded the tastiest, most tender oven tri-tip we'd both ever tasted.

The short cooking time (because we're using high heat) insures the tri-tip is never dried out, but always juicy and delicious.

Ingredient Notes

Tri-Tip — A 4 to 5-pound tri-tip steak is used in this recipe. Although you may leave the fat on, I find it's not necessary. Trim approximately half of the fat off, leaving the rest for added flavor and to keep the tri-tip from drying out.
Santa Maria Dry Rub — Santa Maria Steak is usually seasoned with a tasty rub, which includes salt, pepper, garlic. In this recipe, we use my Santa Maria Dry Rub recipe.
Baste — A simple baste, prepared with oil, vinegar, and garlic is used to generously baste the tri-tip, before applying the rub and right before it goes into the oven.

Cooking Instructions

Tip: Bring the tri-tip to room-temperature by removing it from the refrigerator at least one hour prior to cooking it.

Preheat oven to 425°F.

Baste the tri-tip roast with the remaining oil and vinegar. Heat a large, seasoned cast-iron skillet, then sear the meat on all sides.

Transfer the pan to the heated oven and insert the probe. Set the probe to the desired internal temperature (see frequently asked questions below for suggested temperatures).

Tip: If you don't have a probe, roast the tri-tip, fat-side up, for 10 to 15 minutes per pound.

Remove the oven tri-tip from the oven and tent it with foil. Allow the meat to rest for 10 minutes before slicing.

Recipe FAQ's and Expert Tips

How do you keep oven tri-tip moist?

• Sear the roast before placing it in the oven. This locks in the flavor and the juices.
• Do not overcook the meat. Although I'm guilty of preferring meat cooked to medium-well, cooking it to medium or medium-rare keeps the roast a lot juicier. If someone in your family prefers it cooked more, they can always be served the ends which will be well-done.
• Finally, tenting the meat and leaving it to rest for ten minutes before slicing it allows the juices to redistribute throughout the meat. Will some of the juices still seep out? Absolutely! But there will still be plenty of juices left throughout the roast.

How long do you cook oven tri-tip in the oven?

Cooking tri-tip for 10-15 minutes per pound gives you a roast that is well-done on the ends, and gradually gets rarer towards the center.

When using an oven probe, or a meat thermometer, cook the tri-tip until the internal temperature in the thickest part reads:
125°F for rare
135°F for medium-rare
145° for medium
150° for medium-well
160° for well-done

What goes good with this recipe?

My favorite way to serve tri-tip is drizzled with chimichurri. This spicy Argentinian sauce is loaded with flavor and the perfect complement to the Santa Maria Dry Rub seasoning.

My Santa Maria dry rub recipe is portioned for an average-sized 4 to 5 lb. roast. If your roast is smaller, you can save some of the rub for another purpose. Although it may seem like we're overly seasoning the roast, a lot of the seasoning will remain in the pan once it's cooked.
If you cook the roast while still cold, it will require additional cooking time.
Remember that the temperature of the roast will continue to rise after it's removed from the oven. Keep this in mind when deciding how long to cook and rest the tri-tip.
When eating tri-tip, it's a good idea to slice it across the grain. This shortens the muscle fibers and makes the steak easier to chew. However, if you did this with a large tri-tip, you'd end up with very long slices. I recommend slicing it with the grain to portion it out and slicing it against the grain as you eat it.
