If you’ve got any of my other cooking articles here, you know I’m somewhat of a tri tip expert. I love it. Normally, I do mine on the grill, but there are times (especially when I’m busy) where I’ll cook it in the oven. And you know what? It still tastes great. Here’s how I do it.
First of all, you need to rub / marinade your meat however you like it. There’s no perfect way. I’ve done tri tips all kinds of ways-it’s the cut of meat I use when I experiment. However, you’re going to want some wet works for the cooking. This could be a mixture of olive oil and other ingredients or your preferred marinade.
If your meat is in the refrigerator, take it out for about 5-10 minutes before cooking.
Next, place your tri tip on a baking pan fat side down. Drench a little of your preferred wet works over it and slide it in the middle of your oven. Set your timer for about 45 minutes. Your cooking time might be about 1 hour, but from about the 45 minute mark, you want to pay real close attention to the meat.
Here’s the key. Every 8-10 minutes, add some more marinade over the top of your tri tip. You may end up doing this 6-7 times depending on final cooking time. Remember to take it out before it’s actually done, because it will continue to cook for up to 10 minutes afterward. And I like to wrap mine in foil for 5 minutes before cutting it.
Lastly, if your cut of meat has a fair amount of fat on the fat side, start it in the oven with that side up for about 8 minutes and then flip it for the rest of the duration. If you’ve done everything right, your tri tip from your oven will be very tasty.
