Step-by-Step Instructions for the Tri Tip Roast Slow Cooker

  • Season the Roast:

Pat your tri-tip roast dry with paper towels to remove any excess moisture. This will help the seasoning stick better. Rub the roast generously with salt and pepper, or your favorite spice rub for an extra flavor kick.

  • Sear for Flavor:

Heat a skillet over medium-high heat, adding a tablespoon of olive oil. Once the oil is hot, sear the tri-tip roast on all sides until browned and crispy. This step is essential to lock in the flavors and create a delicious, caramelized crust thanks to the Maillard reaction. Do not skip this step!

  • Deglaze the Pan & Create the Sauce:

After searing, remove the roast and set it aside. In the same skillet, add minced garlic and cook until fragrant. Next, pour in the beef broth and stir to deglaze the pan, scraping up any browned bits. Add the onion soup mix and stir until well combined. This will be the base for your gravy.

  • Assemble & Cook:

Place the seared roast on top of the vegetables in the slow cooker. Pour the broth and gravy mixture over the roast and vegetables. Cover and set your slow cooker to low for 6-8 hours. The low setting ensures that the roast becomes fall-apart tender.

  • Rest & Slice:

Once the cooking time is up, remove the roast from the slow cooker and let it rest for 10 minutes before slicing. Resting is crucial as it allows the juices to redistribute throughout the meat, ensuring every slice is juicy and tender. Slice against the grain for the best texture.

Expert Tips for a Perfect Tri-Tip Roast Slow Cooker

  • Don’t Crowd the Pan: If your skillet isn’t large enough, sear the tri-tip in batches to ensure it gets a perfect crust.
  • Low is the Way to Go: For the most tender tri-tip, set your slow cooker to low. The slow cooking process breaks down the muscle fibers, resulting in a more tender roast.
  • Check for Doneness: Use a fork to test the tenderness—if it easily shreds, it’s done. Alternatively, use a meat thermometer to ensure the internal temperature has reached 190°F for optimal tenderness.
  • Thickening the Gravy (Optional): If you’d like a thicker gravy, mix a tablespoon of cornstarch with a tablespoon of cold water to create a slurry. Stir it into the gravy while it’s still simmering on the stove.
