Ingredients

• 3 lb tri tip or Santa Maria roast (1.36 kg)
• 1/3 cup olive oil (80 ml)
• 3/4 tsp salt + extra for seasoning
• 1/2 tsp black pepper + extra for seasoning
• 1/2 cup jarred roasted red pepper (120 ml)
• 1/3 cup minced shallots or red onion (80 ml)
• 1/4–1/2 tsp red pepper flakes
• 1/4 cup fresh basil leaves (10 g)
• 2 tsp fresh oregano or 1/2 tsp dried
• 2 tsp fresh rosemary or 1/2 tsp dried
• 2–3 cloves garlic, minced
• 1/3 cup balsamic vinegar (80 ml)
• 2 tbsp lemon juice (30 ml)

How to Make Santa Maria Tri Tip in the Oven

1. Whip Up the Marinade: In a food processor, blend olive oil, salt, pepper, roasted red pepper, shallots, red pepper flakes, basil, oregano, rosemary, garlic, balsamic vinegar, and lemon juice. Pulse about 10 times until the mixture is combined but still has texture.
2. Marinate the Meat: Pat the tri-tip roast dry and season with a little extra salt and pepper. Place it in a zip-top bag and pour in the marinade. Seal and massage the bag so the meat is evenly coated. Refrigerate for at least 8 hours or overnight.
3. Get It Oven-Ready: About an hour before cooking, take the roast out of the fridge to come to room temperature. Preheat your oven to 350°F (175°C).
4. Roast to Perfection: Lightly spray a baking dish with non-stick spray. Place the roast in the dish, insert a meat thermometer into the thickest part, and roast for 70–75 minutes or until it hits 135–140°F (57–60°C) for medium-rare to medium.
5. Let It Rest and Serve: Tent the roast loosely with foil and let it rest for 10 minutes. Then, slice thinly against the grain and serve warm.

Tips for a Juicy Tri-Tip Roast

• Don’t skip the marinade time—this is key for deep flavor.
• Room temp roast = even cooking. It’s worth the wait.
• Use a meat thermometer to avoid guessing doneness.
• Slice against the grain to keep things tender.

A Slice of My Story

When I first discovered Santa Maria Tri Tip, it was love at first bite. I was visiting friends in California, and someone casually served this gorgeous roast at a backyard dinner. One juicy, smoky forkful later, I knew I had to recreate it at home.

This oven version lets me bring that same West Coast flavor to my kitchen without needing a grill or a sunny day. And trust me, the leftovers (if you have any!) make killer sandwiches the next day.

Perfect Pairings for Your Tri-Tip Roast

• Creamy mashed potatoes or garlicky mashed cauliflower
• Roasted asparagus or green beans with lemon zest
• Rustic bread for soaking up juices
• A glass of bold red wine or iced tea with lemon

How to Store and Reheat

• Store sliced roast in an airtight container for up to 4 days.
• Reheat gently in a skillet or low oven to keep it juicy.
• You can freeze leftovers—just slice first and wrap tightly.

FAQs

Can I grill this instead of oven-roasting?

Yes! Sear the roast over high heat for 5–7 minutes per side, then finish over indirect heat until it reaches desired doneness.

Can I use a different cut of beef?

You can sub with a sirloin roast, but tri-tip gives that classic texture and flavor.

Do I have to use a food processor?

Nope! A good knife and some elbow grease can get the marinade chunky enough.

A Roast Worth Repeating

If you’ve been looking for a new way to wow your family with minimal stress, this Santa Maria Tri Tip is the answer. From the herb-packed marinade to the juicy slices of roast, every part of this dish is crafted for comfort and flavor.

So go ahead, preheat that oven, put on your favorite playlist, and get ready for a dinner that feels just a little more special than the usual weeknight routine.
