The Tri-Tip goes by so many (often incorrect) names — California cut, Newport steak, sirloin tip, sirloin butt, culotte, bottom sirloin, top sirloin and more — that it’s sometimes confusing.
The term tri-tip is correct and descriptive because the steak is triangular and is the tip of the sirloin.
Serve this main dish with a salad or sauteed greens.

Ingredients

Cherry Tomato Marinara Sauce

One 28-ounce can whole cherry tomatoes (Cento brand)
2 tablespoons extra-virgin olive oil
2 anchovies packed in olive oil
1/3 cup red onion, diced
1 tablespoon capers, drained and rinsed
3 cloves garlic, minced
Pinch red pepper flakes
Kosher salt and freshly ground black pepper
1 teaspoon dried Italian seasoning

Steak

1 tablespoon olive oil
One 24 oz trip-tip steak
1 medium onion, sliced
Kosher salt and freshly ground black pepper
1/2 cup dry red wine (such as Chianti, Montepulciano)
8-10 oz spaghetti
Parmesan cheese and chopped parsley for garnish

Directions

Preheat the oven to 300 degrees F.

Combine all the ingredients for the marinara sauce together in a bowl and set aside.

Heat the olive oil in a Dutch oven or heavy-bottomed pot over medium-high heat. Season the roast lightly with salt and pepper. Put the roast fat-side down in the pot. Cook until the bottom is browned, about 3 minutes, then carefully turn the roast to brown on the other side, an additional 3 minutes. Remove the meat to a plate.

 

Add the onions and stir periodically until they soften and start to brown, about 8 minutes. Stir in the sauce ingredients and wine. Add the meat with all its juices back to the pot. Bring the liquid to a simmer. Cover, transfer the pot to the oven and cook until the meat is very tender about 2 hours. Place the meat on a cutting board and slice into thin slices.

Cook the pasta to the al dente stage. Drain and stir into the sauce in the Dutch Oven. Pour the pasta onto a platter and place the sliced steak on top. Garnish with grated Parmesan cheese and parsley.
