Summer is synonymous with grilling, good company, and unforgettable food. While Labor Day weekend might mark the unofficial end of summer for some, for us, it was a grand celebration of fantastic food and cherished time with friends and family. We kicked off the long weekend with a spectacular get-together, where the aroma of grilled meats filled the air, and laughter echoed through the evening. The menu was designed for maximum flavor and enjoyment, creating memories around every bite.
Among the culinary highlights were some zesty Mojo Beef Kabobs and, the star of the show, this incredible Grilled Beef Tri-Tip Roast served with a luscious Caramelized Three-Onion Sauce. The combination was truly amazing – a symphony of smoky beef and sweet, tangy onions that had everyone asking for the recipe. This dish perfectly embodies what summer grilling should be: delicious, impressive, and surprisingly approachable.
Our gathering was a true potluck delight. My brother contributed his renowned Squash Casserole, a delightful creamy side dish that perfectly complemented the grilled meats. We also made sure to have plenty of grilled corn and all-beef hot dogs for the kids (and the young at heart!). It was one of those truly special parties where the food sparked endless conversations, and guests were eager to take home not just leftovers, but the actual recipes. I even found myself sending home jars of my secret Ancho Steak Seasoning with several eager guests – definitely an interesting party favor that was much appreciated! The sheer deliciousness of everything served that day reaffirmed a simple truth: with food this good, a vegetarian lifestyle simply isn’t for me!
Discovering the Magic of Tri-Tip: A Grilling Favorite
Let’s dive into the star of our recipe: the Tri-Tip. While commonly associated with California cuisine, where it’s a celebrated and widely available cut of beef, its popularity is rapidly spreading across the nation, and for good reason. If you haven’t had the pleasure of trying Tri-Tip before, I urge you to seek it out. It’s a lean, flavorful, and incredibly versatile cut that delivers exceptional results on the grill.
What is Tri-Tip?
The tri-tip roast, also known as a triangle roast, Santa Maria steak, or California cut, comes from the bottom sirloin primal cut of the cow. It’s named for its distinctive triangular shape. This cut boasts excellent marbling and a rich beefy flavor, making it a favorite for grilling and roasting. Because it’s leaner than some other cuts, proper cooking is key to ensure it remains tender and juicy. Its unique grain direction requires specific carving techniques, which we’ll cover in the instructions, to maximize tenderness.
Why Tri-Tip is a Must-Try for Grilling Enthusiasts
For my family, tri-tip in every form is a perpetual favorite and a staple at our gatherings throughout the year. Its robust flavor stands up beautifully to bold seasonings and smoky grill heat. Historically, I’ve often purchased pre-seasoned tri-tip for convenience, but the experience of crafting my own seasoning blend, like our Ancho Steak Seasoning, has been a game-changer. It allows for complete control over the flavor profile, ensuring a truly personalized and unforgettable meal. The ease with which tri-tip cooks to perfection, combined with its fantastic taste, makes it an ideal choice for both novice grillers and seasoned barbecue masters.
The Irresistible Caramelized Three-Onion Sauce
Accompanying our perfectly grilled tri-tip is the star condiment: the Caramelized Three-Onion Sauce. This sauce is nothing short of fabulous, offering a complex depth of flavor that perfectly complements the savory beef. What makes it truly special is the balsamic vinegar reduction, which adds a sophisticated tang and a beautiful glossy finish. The rich, sweet notes of caramelized onions, combined with the sharpness of balsamic, create a harmonious balance that will leave you wanting more. Trust me when I say, once you try this sauce, you’ll want to make it again and again!
Crafting the Flavor: Ingredients for the Caramelized Three-Onion Sauce
This exquisite sauce boasts a trifecta of onion varieties, each contributing its unique characteristics to create a rich and complex flavor profile. A touch of brown sugar balances the tanginess of the balsamic vinegar, resulting in an utterly addictive accompaniment.
- High-quality olive oil for sautéing
- Thinly sliced red onion for a touch of sweetness and vibrant color
- Thinly sliced yellow onion, offering a classic, robust onion flavor
- Thinly sliced green onions (green parts only) for a milder, fresh allium note
- Balsamic vinegar, reduced to a syrupy consistency, providing depth and tang
- Brown sugar, packed, to enhance sweetness and aid caramelization
- Salt and freshly ground black pepper, seasoned to taste
- A hint of Ancho Steak Seasoning (the same blend used on the tri-tip) for cohesive flavor

Ingredients
- 2 lbs beef tri-tip roast
Caramelized Three Onion Sauce
- 2 tbsp olive oil
- 1 red onion thinly sliced
- 1 yellow onion thinly sliced
- 2 bunches green onions green party only, thinly sliced
- ¾ cup balsamic vinegar
- ¼ cup brown sugar packed
- salt and pepper as desired
- ¼ cup Ancho Steak Seasoning – see below
Ancho Steak Seasoning:
- ¼ cup kosher salt or table salt
- 3 tablespoons ground ancho chili powder
- 2 tablespoons ground cumin
- 2 tablespoons dried granulated garlic
- 2 tablespoons coarse-grind black pepper
- 2 tablespoons of sugar
- 1 tablespoon ground thyme
Instructions
-
Prepare the Caramelized Three-Onion Sauce: Heat olive oil in a large non-stick skillet over medium heat until shimmering. Add the thinly sliced red, yellow, and green onions. Cook and stir consistently for 8 to 10 minutes, or until the onions have softened and just begin to take on a light brown color.
-
Reduce the heat to low, allowing the onions to slowly caramelize for about 12 minutes, stirring occasionally to prevent burning and ensure even browning. Increase the heat to medium-high, then stir in the balsamic vinegar. Cook for approximately 4 minutes, stirring occasionally, until the vinegar has reduced by half and thickened slightly. Stir in the brown sugar, then season with salt and pepper to your desired taste. Reduce the heat back to low and continue to cook for another 5 minutes, or until the remaining liquid has evaporated and the onion mixture has a thick, jam-like consistency. Remove from heat and set aside.
-
Prepare the Ancho Steak Seasoning: In a small bowl, combine all ingredients for the Ancho Steak Seasoning: kosher salt, ground ancho chili powder, ground cumin, dried granulated garlic, coarse-grind black pepper, sugar, and ground thyme. Mix thoroughly until well combined. For best results, store in an airtight container and shake well before each use to ensure spices are evenly distributed.
-
Season the Tri-Tip: Generously press the prepared Ancho Steak Seasoning evenly over the entire surface of the beef tri-tip roast. Ensure all sides are well-coated for maximum flavor.
-
Grill the Tri-Tip: Preheat your grill to medium heat. If using a charcoal grill, arrange coals for medium, ash-covered heat. If using a gas grill, adjust burners to achieve a consistent medium temperature (we found our gas grill worked perfectly). Place the seasoned tri-tip roast directly on the grill grates. Grill, covered, for 25 to 35 minutes for medium-rare to medium doneness, turning the roast occasionally to achieve an even crust and cook. The exact grilling time will vary based on your grill’s heat and the thickness of the roast. For precision, remove the roast when an instant-read thermometer inserted into the thickest part of the beef registers 140°F (60°C) for medium-rare, or 155°F (68°C) for medium.
-
Rest and Carve: Once removed from the grill, let the tri-tip roast rest on a cutting board, loosely tented with foil, for a minimum of 10 minutes. This crucial resting period allows the juices to redistribute throughout the meat, ensuring a tender and flavorful result. During this time, the internal temperature will continue to rise by about 5°F (3°C), reaching a final temperature of 145°F (63°C) for medium-rare, or 160°F (71°C) for medium. Carve the roast across the grain into thin slices. Serving against the grain is vital for optimal tenderness, especially with tri-tip. Serve immediately with generous dollops of the warm Caramelized Three-Onion Sauce.

Tips for Grilling Perfection
Achieving a perfectly grilled tri-tip is all about attention to detail. Here are some extra tips to ensure your tri-tip is tender, juicy, and packed with flavor every time:
- Bring to Room Temperature: Before grilling, let your tri-tip sit out at room temperature for about 30-60 minutes. This allows for more even cooking.
- Preheat Your Grill Properly: A hot grill is essential for a good sear. Ensure your grates are clean and well-oiled to prevent sticking.
- Monitor Internal Temperature: An instant-read thermometer is your best friend. Relying solely on cooking time can lead to over or undercooked meat due to variations in roast thickness and grill heat.
- The Importance of Resting: Do not skip the resting step! It allows the meat fibers to relax and reabsorb the juices, resulting in a much more tender and moist roast.
- Carve Against the Grain: Tri-tip has a unique grain pattern that changes direction. Identify the two main grain directions and carve perpendicular to each section for maximum tenderness. This is critical for tri-tip.
- Doneness Levels:
- Rare: 125-130°F (52-54°C)
- Medium-Rare: 130-135°F (54-57°C)
- Medium: 135-140°F (57-60°C)
- Medium-Well: 140-145°F (60-63°C)
- Well-Done: 150°F (66°C) and up (not recommended for tri-tip as it can become tough)
Serving Suggestions: What to Pair with Grilled Tri-Tip
This exquisite grilled tri-tip and caramelized onion sauce pair beautifully with a variety of side dishes, making it suitable for any occasion, from casual backyard BBQs to more formal outdoor dining. Consider serving it with:
- Roasted seasonal vegetables like asparagus, bell peppers, or zucchini.
- Creamy mashed potatoes or a flavorful potato gratin.
- A fresh, crisp green salad with a light vinaigrette to cut through the richness.
- Garlic bread or crusty artisan bread to soak up any lingering sauce.
- Grilled corn on the cob (as mentioned earlier, a perfect complement!).
- A robust red wine, such as a Cabernet Sauvignon or Zinfandel, would be an excellent beverage pairing.
