Ingredients For an Oven Roasted Tri Tip at 275?

To get started, you’ll need the following:

  • Tri-tip roast (1 – 2 pounds)
  • Salt and pepper
  • Any additional desired seasonings, such as garlic powder or oregano

How to choose a good Tri Tip for cooking?

The cut of the tri-tip is very important when it comes to cooking a perfectly juicy and flavorful roast. It should be firm yet tender, with an evenly marbled fat content.

Look for marbling: Marbling refers to the small streaks of fat that are distributed throughout the meat. It adds flavor and juiciness to the tri-tip. Look for a piece with visible marbling, as it indicates tenderness and flavor.

Opt for USDA Choice or Prime grade: The USDA (United States Department of Agriculture) grades beef based on its quality. Choice and Prime grades are typically the highest quality available and have good marbling. Selecting a tri-tip from one of these grades ensures a better eating experience.

Check the color: A fresh tri-tip should have a deep red color. Avoid meat that appears pale or has a grayish tint. Also, be sure to check the “sell-by” or “use-by” date on the packaging to ensure freshness.

Consider the thickness: Tri-tips come in various sizes and thicknesses. Look for a tri-tip that is evenly thick throughout, as it will cook more evenly and provide a consistent texture.

Check for firmness: Gently press the meat with your fingers. A good tri-tip should feel firm and spring back when touched. Avoid meat that feels excessively soft or mushy, as it might be past its prime.

Ask your butcher: If you have a trusted butcher, don’t hesitate to ask for their recommendation. They can guide you in selecting a good tri-tip and might even be able to provide some cooking tips.

Note: If you’re unsure about the quality of your cut, you can always ask your butcher or grocery store meat expert for advice.

Keep in mind that the exact cooking times may vary depending on your oven, so always use an instant-read thermometer to check for doneness.

Perfect Oven Tri-Tip Roast at 275°F

For a mouthwatering and tender oven tri-tip roast, follow this step-by-step recipe that packs tons of flavor and will leave your guests impressed. This recipe caters to a choice-grade, boneless tri-tip roast, weighing approximately 2 to 2.5 pounds. Before diving into the recipe, ensure your tri-tip is well-trimmed and, if possible, marinated overnight for maximum flavor.


  • 1 choice-grade boneless tri-tip roast (2 to 2.5 pounds), trimmed
  • 2 tablespoons olive oil
  • 1 tablespoon Worcestershire sauce (optional)
  • 3 cloves garlic, minced
  • 1 tablespoon fresh rosemary, chopped (alternative: thyme)
  • 1 tablespoon fresh oregano, chopped
  • 1 tablespoon kosher salt
  • 1 tablespoon freshly ground black pepper
  • 1 teaspoon smoked paprika (alternative: regular paprika)
  • 1/2 teaspoon red pepper flakes (optional)


  1. Take the tri-tip roast out of the refrigerator and let it sit at room temperature for 30 minutes to 1 hour before cooking. This step is crucial to ensure the even cooking of the roast.
  2. Preheat your oven to 275°F.
  3. In a small bowl, mix the olive oil, minced garlic, chopped rosemary, oregano, kosher salt, black pepper, smoked paprika, and red pepper flakes (if using) to create a flavorful paste.
  4. If opting to marinate, mix in the Worcestershire sauce to the seasoning paste. Place the tri-tip roast in a sealable plastic bag, add the mixture, and massage it onto the meat. Seal the bag and refrigerate overnight, or for at least 4 hours.
  5. For immediate cooking, evenly coat the tri-tip roast with the seasoning paste.
  6. Place the seasoned tri-tip roast on a roasting rack inside a shallow roasting pan, fat-side up. This ensures that juices will keep the meat moist during the cooking process.
  7. Cook the roast in the preheated oven for approximately 1 hour and 30 minutes to 2 hours, or until a probe thermometer inserted in the thickest part of the roast reads 130°F for medium-rare or 140°F for medium – depending on your desired level of doneness.
  8. Remove the roast from the oven and tent it loosely with aluminum foil. Allow the meat to rest for 15 minutes before slicing. This resting period will enable the juices to redistribute and preserve tenderness.
  9. Slice the roast against the grain. This will ensure that each cut is more tender and easier to chew.


Serve your delicious oven tri-tip roast with tasty side dishes like roasted vegetables, mashed potatoes, or a simple green salad. Enjoy the scrumptious satisfaction of a flavorful and tender tri-tip roast, cooked to perfection at 275°F.
