Large Portions

• 1). Wrap whole tri-tip steaks or roasts, unsliced, in aluminum foil.
  
  
• 2). Place the foil-wrapped steak in a preheated 350-degree F oven for 15 to 20 minutes. Bake larger pieces of meat at a lower temperature for a longer time and bake smaller pieces of meat at a higher temperature for a shorter time.
  
  
• 3). Flip the tri-tip over halfway through the cooking time.
  
  
• 4). Allow the steak to rest, in foil, for about five minutes before slicing.
  
  

Small Portions

• 1). Heat a large skillet to medium-high heat. Coat it with butter or oil.
  
  
• 2). When the skillet is hot, quickly add the tri-tip.
  
  
• 3). Sear steaks for about two to five minutes per side, depending on its thickness. If you're reheating cubes or strips of tri-tip, stir the meat constantly.
