There’s nothing like the deep, smoky flavor of a Santa Maria-style tri tip roasted over oak. I’ve spent years perfecting this method, blending classic technique with pitmaster instincts to achieve tender, flavorful results every time.
This approach respects tradition while delivering restaurant-quality meat with a beautiful crust. The oak smoke infuses the beef with an aroma that’s impossible to replicate indoors, making it the centerpiece of any outdoor gathering.

The tri tip is non-negotiable—look for well-marbled, untrimmed roasts (about 2-3 inches thick) from a reputable butcher or Costco. The fat cap protects the meat during grilling while adding flavor. Oak wood is traditional for Santa Maria-style; avoid mesquite (too harsh) or pine (toxic). If using wood chips instead of chunks, soak them first for a slower, more controlled smoke.
No oak? Hickory or pecan work as substitutes, though the flavor profile shifts slightly. For the dry rub, freshly ground spices make a noticeable difference—pre-ground loses potency quickly. If you must use table salt instead of kosher, reduce by half (it’s much saltier by volume). The vinegar adds brightness; apple cider vinegar can stand in if that’s what you have.
Apply the rub up to 12 hours ahead for deeper penetration, or just before grilling if short on time. Leftovers (if any) keep 3-4 days refrigerated or 3 months frozen. Slice against the grain for maximum tenderness—this cut has two grain directions, so rotate the board halfway through carving.

Step-by-Step Instructions for Grilled Tri Tip Roast
Master the Santa Maria technique with these precise steps for oak-grilled perfection every time.
Step 1: Create the Dry Rub and Season the Tri Tip
In a small bowl, combine 1.5 tbsp Coarse Kosher Salt, 1.5 tbsp Freshly Ground Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tbsp Dried Rosemary, 1 tbsp Dried Parsley, 1 tsp Paprika, and 1 tbsp Beef Bouillon Powder. Crush the dried herbs between your fingers to release their aromatic oils.
Pat the 3 lb Tri Tip Roast dry with paper towels, then rub it all over with 0.25 cup Olive Oil and 2 tbsp Red Wine Vinegar. The oil helps the dry rub adhere while the vinegar tenderizes the surface. Apply the spice mixture liberally, pressing it into the meat on all sides. Let it sit at room temperature for 30-45 minutes while you prepare the grill.
Step 2: Set Up the Grill for Indirect Heat
Prepare your grill for two-zone cooking. On a charcoal grill, bank the coals to one side. On a gas grill, preheat all burners to high, then turn off one side. Add 4 cups Oak Wood Chunks directly to the hot coals or in a smoker box for gas grills. You want a steady temperature of 275-300°F on the indirect heat side.
Wait until you see thin, blue smoke—not thick white smoke—before adding the meat. The oak should smolder gently, infusing the roast with that signature Santa Maria flavor. Place a drip pan under the indirect heat zone to catch renderings and prevent flare-ups. Clean and oil the grates thoroughly to prevent sticking.
Step 3: Grill the Tri Tip to Perfect Doneness
Place the tri tip roast on the indirect heat side of the grill, fat cap up. Insert a meat thermometer into the thickest part of the roast, avoiding the fat cap. Close the lid and cook undisturbed for 30-40 minutes, maintaining the grill temperature between 275-300°F.
Flip the roast once when it reaches an internal temperature of 110-115°F. Continue cooking until the internal temperature reaches 130-135°F for medium-rare, which should take about 45-60 minutes total. The meat is ready when the thermometer reads your target temperature and the surface develops a deep, mahogany crust.
Step 4: Rest and Slice Against the Grain
Transfer the tri tip to a cutting board and tent loosely with foil. Let it rest for 10-15 minutes—this allows the juices to redistribute throughout the meat. The internal temperature will rise 5-10°F during this time (carryover cooking), so remove it from the grill slightly before your target doneness.
To slice, first identify the grain direction, which runs differently in each half of the tri tip. Cut the roast in half where the grain changes direction, then slice each piece perpendicular to its grain into ¼-inch thick slices. This ensures maximum tenderness. Serve immediately while still warm.
Pro Tips For Making Grilled Tri Tip Roast
- Reverse Sear First: Start with indirect heat at 225°F until the tri tip hits 115°F internally, then sear over direct oak fire for 2-3 minutes per side. I learned this the hard way—going straight to high heat gives you a burnt exterior and raw center.
- Salt Generously: Use about 1 tablespoon of coarse kosher salt per pound of tri tip, applied at least 40 minutes before grilling. Sounds like a lot, but the salt penetrates deep and makes a real difference in flavor.
- Don’t Overflip: Resist the urge to constantly turn the meat—flip only once during the sear to get those perfect crosshatch grill marks. After ruining a few roasts by fidgeting, I finally figured out that patience wins.
- Rest Under Foil: Let the tri tip rest for 10-15 minutes under loose foil after grilling. My grandmother swore by this, and she was right: it keeps the juices from pooling on the cutting board.
Health Benefits of grilled tri tip roast
Rich Protein Source
Tri tip is a lean, flavorful cut packed with high-quality protein—about 40 grams per 6-ounce serving. This supports muscle repair and growth, making it ideal for active lifestyles. I love how it keeps me energized during long days at the grill. 💪
Iron and Zinc Boost
Beef is one of the best sources of heme iron, which your body absorbs more easily than plant-based iron. A serving provides about 20% of your daily iron needs and 40% of your zinc, both crucial for immune function and metabolism.
B Vitamin Powerhouse
This cut delivers a full spectrum of B vitamins, including B12 for nerve health and B6 for energy metabolism. A 6-ounce portion covers nearly all your daily B12 needs. I notice a difference in my energy levels when I include beef regularly.
Low in Saturated Fat
Compared to other beef cuts, tri tip is relatively lean with only 8 grams of saturated fat per serving. Trimming visible fat before cooking can reduce this further. It’s a great option for those watching their fat intake without sacrificing flavor.
Essential Amino Acids
This dish provides all nine essential amino acids your body can’t produce on its own. These building blocks are vital for everything from tissue repair to hormone production. A well-marbled roast ensures you get the full nutritional profile. 🥩
Vitamin D and Selenium
Beef contains vitamin D and selenium, antioxidants that support immune health and cell function. While amounts vary, grass-fed tri tip tends to have higher concentrations of these nutrients. I always choose local, grass-fed when available.
