Tri-Tip Roast Recipe with Gluten Free Gravy

I made this tri-tip roast recipe with gluten-free gravy right before I left last week to take care of my father. Now that it’s fall, it’s time for some comfort food, and with Dad terminally ill, I surely needed the comfort. Plus, the tri-tip roast was on sale and I couldn’t pass up the bargain. I like roast because it lasts for more than one meal in our house since it’s just the two of us. And this left my hubby plenty of food in the freezer to tied him over while I was gone. He found it comforting, too, since I was leaving. Not to mention, this tri-tip roast recipe is very flavorful! Enjoy.

I know the gluten free newcomers may have questions on how to thicken gluten free gravy. This is just one way. I like to use potato starch in my beef gravies, and tapioca starch in my Asian dishes. Cornstarch works well with meat, too, but I like to remain as corn-free as possible. If using cornstarch I suggest using Bob’s Red Mill brand, as it is gluten free and GMO-free.

Yield: 7 servings

Tri-Tip Roast Recipe with Gluten-Free Gravy


  • 3.5 pounds Tri-Tip Roast, browned
  • 1 Tablespoon oil (I used extra virgin olive oil.)
  • 1 cup yellow onion, chopped
  • 2 Tablespoons garlic, minced finely
  • 1-1/2 cups gluten-free low sodium chicken broth
  • 1 teaspoon dried rosemary
  • 1 teaspoon oregano
  • 1/2 teaspoon ground thyme
  • pepper, to taste
  • 2 Tablespoons potato starch
  • 4 Tablespoons filtered water


  1. Brown roast in oil on high heat until brown on all sides.
  2. Add roast to crock pot.
  3. In same frying pan as you browned the roast, add onion, and extra oil if needed; saute until tender; add garlic and saute for 30-60 seconds.
  4. Add onion, garlic, seasonings and broth to crock pot and stir.
  5. Cook on low for 8-9 hours. The last hour is when the roast will become very tender.
  6. Remove roast from crockpot and set aside on a cutting board.
  7. Strain the broth into a sauce pan and bring to a boil.
  8. In a small bowl add potato starch and water, whisk until blended. Add this mixture to the boiling broth and stir constantly until thickened. Add salt and pepper to taste.
  9. Slice roast and serve topped with gluten-free gravy. Mashed potatoes are always a great compliment to roast and may be served topped with gravy, as well.
