Santa Maria-style tri-tip steak rubbed with garlic and spices and grilled over red oak is a Central California family BBQ tradition. This lean, high protein, carnivore-worthy cut is juicy, flavorful, and easy to master.
Trim the tri-tip roast of any large surface fat, then pat dry with paper towels for an even sear.
Mash garlic cloves into a paste and combine with kosher salt, black pepper, paprika, oregano, onion powder, and olive oil to form a thick rub.
Massage the rub evenly onto all sides of the beef, cover, and let rest at room temperature for 45–60 minutes to promote even cooking.
Preheat your grill for a two-zone fire (medium-high heat on one side, indirect on the other), ideally using red oak wood for authentic flavor.
Sear the tri-tip over direct heat for about 6–8 minutes per side until deeply browned, then transfer to indirect heat; cover and grill for 20–30 minutes more, turning as needed, until an internal thermometer reads 130–135°F for medium-rare.
Remove from heat, tent loosely with foil, and let rest 10–15 minutes before slicing thinly across the grain to ensure maximum juiciness.
