Marinated Tri-Tip in a Cast-Iron Skillet

Leave a Comment

Jump to Recipe Print Recipe

Few dishes capture the essence of bold, smoky flavors and juicy tenderness quite like a perfectly marinated tri-tip steak. Originally popularized in California’s Santa Maria Valley, this cut has become a favorite among steak enthusiasts. The best part is that your cast-iron skillet is all you need to achieve that beautifully seared crust and mouthwatering tenderness.

This recipe takes tri-tip to the next level by marinating it in a rich blend of garlic, herbs, and spices, ensuring every bite is packed with flavor. The cast-iron skillet allows for even cooking, giving the steak a deep caramelization while locking in its juices. Whether you’re preparing a weeknight dinner or a special occasion meal, this method delivers steakhouse-quality results right from your stovetop. Pair it with roasted vegetables, a fresh salad or creamy mashed potatoes for a satisfying meal.

Instructions

Marinate the Tri-Tip Roast

Place the whole tri-tip roast on a food safe cutting board. Trim down the fat cap to about ¼-inch thick. Use a fork to poke holes in both sides of the roast.

Trim the rubbery fat from the tri-tip.

Trim some of the fat from the tri-tip.

Use a fork to poke holes in boths sides of the tri-tip.

Poke holes in both sides of the tri-tip.

Mix all marinade ingredients in a medium bowl. Place the tri-tip in a vacuum sealed food bag or in non-reactive container. Add the marinade and seal the bag or cover with plastic wrap.

Mix the marinade ingredients.

Mix the marinade in a medium bowl.

Seal the roast in a vacuum bag.

Place the roast in a vacuum bag or non-reactive container and add the marinade.

Refrigerate for 8 hours. Turn it over after 4 hours.

Remove the tri-tip from the refrigerator 45 minutes before cooking and let it come up to room temperature. Preheat a large cast iron skillet over medium-high heat to about 400°F.

Cook the Tri-Tip Roast

Remove the tri-tip from the marinade, discard the marinade and pat the roast dry. Place a temperature probe into the thickest part of the roast. If you don't have a wired temparuture probe, use an instant-read thermometer to test the temperature while cooking.

Once your skillet is hot, add a few tablespoons of olive oil to the skillet. Place the tri-tip in the cast iron pan fat cap (also called the fat side) down and 3-4 minutes, or until browned.

Flip the steak and sear the other side for 1-2 minutes, ensuring a well-developed crust., and then sear that roast for about 3-4 minutes on each side. You want to get a nice brown crust on it. You want to get a nice brown crust on it. Flip the roast over and sear the other side for another 3-4 minutes.

Next, reduce the heat to medium-low. Continue the cooking the tri-tip to your desired doneness. I like my tri-tip medium-rare, so I cooked it for about 10-12 minutes total.

Remove the roast from the skillet when the internal temperature is 5°F below your desired temperature. The internal temperature will continue to climb while it is resting.

For the best results, transfer the roast to a cutting board, tent loosely with aluminum foil, and let the steak rest for at least 5-10 minutes. This helps the juices redistribute for a tender steak. Slice the perfectly cooked tri-tip against the grain into thin slices, about ¼-inch thick, to enhance its tenderness. The grain in a tri-tip can run in different directions so adjust the angle of cutting as the grain changes.

Add oil to the cast-iron skillet.

Add oil to a hot skillet.

Slice the tri-tip across the grain.

After resting for 5-8 minutes, cut across the grain and serve.

Variations

If you prefer a dry brine instead, mix 1 tablespoon of kosher salt with 1 tablespoon of freshly ground black pepper. Pat the mixture onto both side of the tri-tip. Place in a non-reactive pan and refrigerate overnight.

Equipment

A light weight carbon steel skillet works just as well as a heavy cast iron skillet.

Storage

Store leftover tri-tip roast in an airtight container in the refrigerator for up to 3 days.

Top Tip

To get a good sear, make sure your skillet nice and hot before adding the tri-tip. Also, makes sure to pat the roast dry before searing. A wet roast does not sear well.

Final Thoughts

This simple recipe is one of my favorite ways to prepare this flavorful cut of meat indoors. The combination of a good marinade, a hot skillet and a precise cooking process results in a perfectly cooked cut of beef with an irresistible beefy flavor. Next time you’re at the grocery store, grab a tri-tip roast and give this method a try—you won’t be disappointed!
