What is another name for Tri-Tip?

Tri-tip is a beef loin roast and can also be labeled as Triangle Steak, Bottom Sirloin Steak, or Santa Maria Steak are all similar cuts of steak. Tri-Tip is most often found labeled as such on the West Coast. Any well-marbled cut of meat will do.  The size roast I cooked is 3 pounds. It’s also known as Tri-Tip Steak, often cut into smaller “steaks” or Beef loin tri-tip roast. It’s a fairly lean cut of meat, so if you follow my cooking instructions it will result in tender meat.

Should I cut my roast in half before cooking?

I cut mine in half, it fits in the pan nicely when cut in half. It ensures it’ll cook quicker and more evenly as the two sides of the roast are often different thicknesses and you can remove one portion if it ‘s done cooking before the other. And it makes it easier to slice as you can see the grain and cut against it for tender slices of meat.

Cutting it into more manageable pieces allows it to fit into a skillet better as well.

Since the direction of this beef loin goes in different directions this method makes it easier to slice when it’s done cooking as well. Cut against the grain for tender slices of tri-tip.

Searing the meat in a hot skillet ensures the meat will hold its juices as it cooks, and that helps the meat stay tender as well.

How long to cook tri-tip in oven at 350?

It will depend on the size of your roast, my roast was 3 lbs. It reached 135° (medium rare) in 25 minutes.

How long should I let the roast rest before slicing?

Allow the roast to rest for 10-15 minutes, this will allow the heat to finish cooking the meat and let the juices absorb into the meat. If you do have any meat juices on the cutting board after you’ve sliced the meat, reserve them for a great tasting gravy.

You can cook the tri-tip on the grill, just preheat the grill to 350-400° Place the tri-tip on the grates of the grill on in the skillet. Brown it on all sides. Then close the lid and check on it every 5-10 minutes with a meat thermometer until it’s done. The temperature of a gas grill or charcoal grill will often vary during cooking time, you know your grill best. Use a meat thermometer to check for doneness.

How do I cook this on the grill?

Basically the same, preheat the grill and get it nice and hot. The grill drops the temperature as soon as you open it. Then just put the tri-tip on the grill grates, maintain a 350° temp on the grill, and turn the roast to brown on all sides nicely. Cutting the tri tip in half allows for faster cooking and ensures it’ll all be cooked to the temperature you want. I prefer a medium rare, really pink inside, as it reaches 130°-135° degrees, remove it from the grill and allow it to rest for at least 10 minutes. Slice and serve.

Can tri-tip be cooked in a cast iron skillet, yes just place the skillet on the grill and turn to cook meat evenly.

A delicious roasted beef that is tender and juicy and perfectly seared on the outside and perfectly cooked inside.
Prep Time10 minutes
Cook Time25 minutes
Total Time35 minutes
Course: Main Dish
Cuisine: American
Servings: 8 servings


  • 3 lb Beef Tri-Tip Roast
  • 1/2 teaspoon coarse salt
  • 1/4 teaspoon coarse black pepper
  • 1 tablespoon oil


  • Preheat oven to 350°
  • Heat a cast-iron (or oven-safe skillet) until it's very hot.
  • Slice the meat in half at the center if you prefer. It's easier to handle and will ensure each portion will cook evenly. Tri-Tip is an unusual shape (triangular) so 2 even oval portions are easier to manage while searing and cooking time will be a little quicker and both pieces will cook evenly.
  • Sear the outside of the beef in a tablespoon of oil in the hot skillet.
  • Turn the beef while it sears, so that all sides are well browned on all sides.
  • Place the skillet into the oven for about 25 minutes.
  • Test the meat with an oven thermometer and remove the pan from the oven when the meat reaches 135° for medium rare.
  • I prefer my beef medium-rare.
