This marinade guarantees your tri-tip will be flavorful and tender (unless you screw it up). I serve my tri-tip sliced and with a little marinade. This recipe will also work for sandwiches.
I prefer the trip-tip strips, although this same recipe works with tri-tip roasts.
Ingredients for the Marinade
2/3 cup olive oil
1/3 cup balsamic vinegar
2 tablespoons soy sauce
2 tablespoons Worcestershire
1. Pierce the tri-tip with a fork numerous times (or score with a knife).
2. Either place the tri-tip in a shallow glass dish or in a large Ziploc bag. Cover with marinade. Allow to marinate for at least an hour, and for up to 24 hours. (I usually do 4-8 hours).
3. Place tri-tip on center rack of heated BBQ Grill. Cook over medium-high heat until the center of you meat reaches 115 degrees (If you're using 1 inch thick strips, this will take 3-5 minutes per side). This will produce red/rare center meat and medium rare (pink) meat on the ends. (Quality instant-read meat thermometers are a must unless you are an experienced cooker and can test meat done-ness by feeling the cuts. NEVER cut the meat open to check done-ness, it will dry out the meat).
4. Slice and serve! Great with baked potatoes and a variety of green veggies including asparagus, broccoli, and Brussel sprouts.
