Marinade and Seasoning
- Marinate the tri-tip overnight in a mixture of Worcestershire sauce, salt, pepper, garlic powder, and apple cider vinegar.
- Alternatively, you can simply season the tri-tip with a dry rub of salt, pepper, and other spices like paprika, garlic powder, and Cajun seasoning.
- Let the seasoned tri-tip sit at room temperature for 30 minutes before cooking.
Cooking Methods
- Grill the tri-tip at 350-400°F, flipping frequently, until it reaches an internal temperature of 130-140°F for medium doneness.
- Smoke the tri-tip at 225°F until it reaches 115-120°F internal, then sear it to finish.

Understanding Tri Tip
Anatomy of the Tri Tip Cut
Knowing where the tri tip sits on the cow can be a game-changer. This triangular cut comes from the bottom sirloin. It’s richly marbled with fat, giving it an incredible flavor and tenderness when cooked properly. You’ll often hear it described as having a beefy, robust profile.
Comparing Tri Tip to Other Cuts
Tri tip stands out against brisket, sirloin, and ribeye. While brisket requires long, slow cooking for tenderness, tri tip cooks quicker yet remains juicy. Ribeye has more fat, and sirloin tends to be leaner. Tri tip is a balanced, flavorful option that’s versatile for various cooking methods.
Preparation Before Cooking
Selecting the Right Tri Tip at Costco
Quality starts with the right piece of meat. Look for well-marbled and evenly colored tri tip. Costco offers various package sizes; aim for one that’s around 2-3 pounds for optimal cooking.
Trimming and Cleaning the Tri Tip
Remove excess fat and the silver skin to ensure even cooking. Use a sharp knife to make clean cuts, minimizing waste. Proper trimming sets the stage for perfecting how to cook Costco tri tip.
Marinating and Seasoning
Choose a marinade depending on your flavor preference—acidic (like vinegar), enzymatic (like pineapple juice), or oil-based (olive oil). Essential spices include garlic powder, black pepper, and paprika. Marinate for at least 2 hours, but overnight yields the best results.
Cooking Methods
Grilling Tri Tip
Utilize both direct and indirect heat. For searing, place the tri tip directly over the flames, then move it aside for indirect cooking. Whether you use a gas or charcoal grill, ensure the meat reaches the desired internal temperature.
Oven-Roasting Tri Tip
Preheat the oven to 425°F. A cast iron skillet works wonders. Sear the tri tip on the stove first, then transfer to the oven. Keep a meat thermometer handy for accuracy.
Sous Vide Tri Tip
Sous vide ensures a uniformly cooked tri tip. Set the temperature to 131°F for medium-rare. After cooking, finish with a sear on the grill or skillet to lock in flavors and achieve a crusty exterior.
Smoking Tri Tip
Wood chips like oak or hickory are ideal. Preheat the smoker to 225°F. Smoke until the desired internal temperature is reached. The result? A delectable smoky flavor that permeates the meat.
Cooking to the Right Temperature
Importance of Internal Temperature
Using a meat thermometer is essential. The perfect tri tip is medium-rare at 130-135°F. Resting post-cook ensures juices redistribute for maximum flavor and tenderness.
Resting the Meat
Always rest your tri tip. Wrap it loosely in foil for about 10-15 minutes. This allows the juices to settle, ensuring every slice is moist and flavorful.
Slicing and Serving
Proper Slicing Technique
Identify the grain, then slice against it. This method ensures tenderness. Keep your slices roughly 1/4 inch thick for the best texture and flavor.
Serving Suggestions
Serve tri tip with classic sides like mashed potatoes and roasted vegetables. For a fresher twist, consider adding a garden salad or grains. Enhance the dish with complementary sauces like BBQ sauce or chimichurri.
Tips and Tricks for the Best Tri Tip
Enhancing Flavor and Tenderness
Dry brining can elevate your tri tip. Rub the meat with salt and let it rest in the fridge for a few hours. Decide between a rub or marinade based on your flavor preference.
Common Mistakes to Avoid
Avoid overcooking by keeping trusty meat thermometers nearby. Improve slicing techniques to maximize tenderness. Never skip resting—this step is crucial for juicy meat.
Variations and Recipes
Tri Tip Sandwiches
Select bread with a sturdy crust like ciabatta or baguette. Add toppings such as caramelized onions, arugula, and a dollop of BBQ sauce.
Tri Tip Tacos
Use either corn or flour tortillas. Top with fresh salsa, avocado, and cilantro for a burst of flavor. The versatility of tri tip shines in taco form.
Tri Tip Salads
Choose a base like leafy greens or grains. Add-ins such as cherry tomatoes, cucumbers, and feta cheese elevate your salad game. Dress with a light vinaigrette.
Storing and Reheating Leftovers
Proper Storage Techniques
Refrigerate or freeze leftovers promptly. Use airtight containers to maintain freshness. Proper storage keeps your tri tip ready for future meals.
Reheating Without Drying Out
Reheat in the oven at a low temperature. If using a microwave, cover and add a bit of liquid to retain moisture. Reheating with sous vide is also effective for bringing leftovers back to life.
