Lentil Seitan Roast with Mushroom Sage Gravy and Roasted Harvest Vegetables…..must be Thanksgiving

Lentil Seitan Roast with Mushroom Sage Gravy

Lentil Seitan Roast with Mushroom Sage Gravy

This weekend is Canadian Thanksgiving. Growing up in Australia, we did not celebrate Thanksgiving, but living here, I just love this holiday.

The scenery at this time of the year is just beautiful. Where I live. in Northern Ontario, it is a vibrant mix of dark green, vivid red, burnt orange and bright yellow leaves all mixed in together and situated amongst rocky outcrops and pristine lakes.

While I joke that I hate the Fall because I know Winter is just around the corner (and I am definitely a Summer girl, give me a beach and sunshine and I am happy), the truth is, Thanksgiving weekend is truly magical here.

Last year I tried making a Tofu Turkey, which turned out OK, but not exceptional. This year I am making a Lentil Seitan Roast which is totally delicious. It is stuffed full of mushrooms, leeks, garlic and cranberries and then smothered in Mushroom Sage Gravy…….totaly mouthwatering.

I will also be making  Scalloped Twin Potato’s (white and sweet potato’s in a creamy garlic sauce) and Brocoli with CauliCheez Sauce. Both these recipes will follow in the next day or so.

If you are in Canada, I know this is posting too close to Thanksgiving for you to try, but it is also perfect for the Christmas dinner table. For my American followers, this might be perfect timing for your celebration next month. For everyone else, again, it is perfect for a Christmas dinner, or just because you feel like a wonderful tasty roast.

Lentil Seitan Roast

Serves 8


  • 2 tblspns olive oil
  • 6 oz mushrooms finely diced
  • 2 Leeks sliced finely
  • 4 cloves garlic minced or grated
  • 2 tblspns fresh thyme chopped
  • salt and ground pepper to taste
  • 1/4 cup fresh breadcrumbs
  • 1/4 cup vegetable broth
  • 1 tblspn lemon juice
  • 1/4 cup dried cranberries

In large pan, saute mushrooms and leeks in olive oil over medium heat until soft, 5 – 10 mins. Add garlic and thyme and continue to cook for additional 2 mins. Add salt and pepper to taste.

Add breadcrumbs and mix well. Cook until breadcrumbs begin to toast and mixture is quite dry (make sure to stir often to prevent burning).

Remove from heat, add in broth, lemon juice and cranberries.  Stir to mix well and complete coat breadcrumb mixture. Set aside.


  • 3 – 6 cloves garlic, minced or grated
  • 3/4 cup cooked green lentils
  • 1 1/2 cups vegetable broth
  • 1 tblspn poultry seasoning
  • 3 tblspns soy sauce
  • 2 tblspns olive oil
  • 2 cups vital wheat gluten
  • 1/2 cup nutritional yeast
  • 1 tspn fennel seeds crushed
  • 1 1/2 tspns sweet paprika
  • 2 tspns dried thyme
  • 2 tspns dried sage
  • freshly ground black pepper to taste

Pre-heat oven to 350 F

Place garlic, lentils, vegetable broth, poultry seasoning, olive oil and soy sauce in food processor. Process until fairly smooth.

In large bowl, mix together all remaining ingredients. Mix well.

Add lentil mixture to dry mixture. Combine well and work into a stiff dough. Knead for a few minutes to make sure everything is incorporated.

Form the “dough” into a flat rectangle that is approx 12 by 10 inches. Place the filling in the centre of the rectangle and form it into a log shape using your hands to squeeze it tightly.  The log should reach to within 2 inches on each side of the “dough”.  Bring the front and back of the “dough” up and over the filling to meet at the top.  Make sure the seam is totally joined by squashing together. Close the ends by squashing the dough togeher.

Place three large sheets foil on workspace. Gently transfer roast to the centre of the foil and wrap up completely, making sure the roast is completely secure.

Place on baking sheet and bake for 1 – 1/2 hours. Every 15 mins, turn the roast on the baking sheet so that every side is in contact with the baking sheet at some time (this will allow the entire roast to brown nicely). After 1 hour, check to see if the roast feels solid by gently squeezing with a pair of tongs. If still soft, allow to cook longer.

Once cooked remove from oven and allow to cool in foil before unwrapping and slicing. This will give the best result. I make this the day before it is required and leave it in the foil overnight in the fridge (after cooling) then place back in the oven, still in the foil for 20 mins to reheat prior to serving.

Mushroom Sage Gravy

Serves 8

  • 4 cups vegetable broth
  • 3 tblspns corn starch
  • 1 medium onion, finely diced
  • 2 tblspns olive oil
  • 16 oz mushrooms, finely diced
  • 4 – 6 cloves garlic minced or grated
  • 2 tspns dried thyme
  • 1 tspn dried sage
  • salt and ground black pepper to taste
  • 3 tblspns nutritional yeast

In large bowl or jug mix together vegetable broth and cornstarch until dissolved. Set aside.

In large pot over medium heat, saute onions in oil for 5 mins until soft. Add mushrooms, garlic, thyme, sage, salt and pepper and continue to cook for additional 5 mins.

Add vegetable broth/cornstarch mixture and nutritional yeast. Continue to cook over medium heat for 20 mins, stirring often.

Gravy can be served as it is, or if you prefer a smoother gravy, allow to cool slightly then transfer to a blender and blend gently until smooth. You may need to add a little water or broth if too thick.

Roasted Harvest Vegetables

This is not really a recipe. Just take whatever vegetables you like, cut into serving size pieces, toss in a little olive oil and sprinkle with black pepper and sea salt to taste.

Place in a baking pan and roast in oven at 375 F for approx 20 – 40 mins depending on vegetables used.
