  • Sauté the onions and mushrooms together until lightly browned, using a little of the vegetable broth to keep it from sticking.
  • Add the garlic, thyme, smoked paprika, cracked pepper, dijon mustard, balsamic vinegar and a little of the remaining vegetable broth and cook for a few minutes.


  • Preheat oven to 400°F
  • Stir the flax meal into the 1/3 cup of water and let sit for a few minutes.
  • Add the oat flour, almond meal, arrowroot flour and nutritional yeast to a mixing bowl and stir well.
  • Add the flax meal mixture and mashed sweet potatoes to the dry mixture in the mixing bowl and blend well, pressing it into a ball to finish.
  • Place the dough ball onto a piece of parchment paper and press into a rectangular shape with your hands.
  • Place another piece of parchment paper on top of the dough and roll into a 12 inch by 8 inch rectangle with a rolling pin.
  • Remove the top piece of parchment.


  • Place the parchment paper with the rectangular crust onto a baking tray.
  • Place the baking tray in front of you so that the 12 in measurement is the width.
  • Place the thawed spinach in the center of the dough making a 3 inch wide line leaving about a 1/2 inch of the dough at the ends uncovered.
  • Spoon the mushroom/onion mixture on top of the spinach making a mound being sure to keep the egde of the dough uncovered.
  • Using the parchment paper to lift the dough, raise the side portion of the dough up and halfway over the mushroom/onion mound and then gently peel back the parchment paper. Lift the opposite side of the dough with the parchment paper over the other side overlapping the dough at least 1/2 and inch. Lightly press the center seam just enough so that the dough sticks to itself. Gently crimp the ends together so that the filling is completely enclosed like an envelope.
  • Make a cross-hatch pattern on the top by gently making diagonal cuts into the surface of the dough being sure not to cut all the way through, repeating the diagonal pattern in the opposite direction to finish the pattern.
  • Bake for 40 minutes.
  • Optional: 10 minutes before it is done baking you can baste with the remaining vegetable broth and then let it finish baking.


  • Sauté the mushrooms in a saucepan until moisture is cooked out and they are slightly browned.
  • Add mushrooms, 1/2 of the vegetable broth, smoked paprika, onion powder and arrow root flour to a blender and blend until smooth.
  • Pour mixture back into the saucepan along with remaining vegetable broth and cook until desired thickness.
  • Stir in miso paste.

  1. Hey guys, I have a question about your food info. Is the calories and sodium and whatnot listed per serving or for the dish as a whole? I only wonder because I’ve got some liver issues and have to watch my intakes on some things and the doc says I need to chill out on the salt intake. Thanks in advance, love every recipe I’ve tried of yours so far. Especially the nacho cheese sauce 🙂 Yall rock!

    1. The nutritional info is supposed to be per serving. Unfortunately the sodium amounts aren’t always correct because in the recipe calculator that we use there are no choices for us to select for things like low sodium vegetable broth or canned goods that contain no salt. If you want to make this even lower sodium, you can leave the replace the dijon mustard for lemon juice.

  2. This is great! I used an orange sweet potato and it gave it a nice color. I didn’t have spinach but was just fine without it. I did cook the lentils with onions and spices so it made it even more delicious. The mushroom mixture was SOOO good! The gravy was fantastic… a real show stopper for sure. Thank you for this recipe! Happy holidays!
