Ingredients
  • 1 medium spaghetti squash about 3 pounds
  • 8 ounces sliced mushrooms1 clove garlic minced
  • 1 1/2 cups low-fat spaghetti sauce packaged or homemade
  • 1 cup spinach optional
  • salt and freshly ground black pepper to taste
FILLING
  • 2 cloves garlic peeled
  • 1 14-ounce package extra-firm tofu not silken
  • 1 cup fresh basil packed
  • 2 tablespoons nutritional yeast
  • 1 teaspoon salt if you use
  • 1/8 teaspoon cayenne pepper optional
CHEESE SAUCE
  • 1 cup plain sugar-free non-dairy milk
  • 1/4 cup nutritional yeast 
  • 1/4 cup raw cashews about 1 ounce (optional, but very good)
  • 2 tablespoons potato starch or cornstarch
  • 1 tablespoon lemon juice
  • 1/2–3/4 teaspoon salt if you use
  • 1/2 teaspoon dry mustard
Preparation
Instructions
  1. Cook the spaghetti squash. You can bake it, microwave it, or do as I did and pressure cook it. To pressure cook, cut the squash in half and scoop out the seeds. Place a steamer basket in your pressure cooker, add 1 cup of water, and place the squash halves in the basket. Seal pressure cooker and cook at high pressure for 8 minutes. Release pressure, uncover, and allow the squash to cool until you can handle it comfortably.
  2. Using a fork, scrape out the strands of “spaghetti.” It may take a little effort and going “against the grain.” Put the squash strands into a colander set over a large bowl and set aside. (You can cook the spaghetti squash ahead of time as long as you drain it well before using.)
  3. Heat a medium-sized sauce pan. Add the mushrooms and 1 clove chopped garlic, along with 1 tablespoon of water. Stir and cover tightly. Cook, stirring every 60 seconds, until the mushrooms soften and exude their juices, about 3 minutes. Uncover and cook until most of the liquid evaporates. Season lightly with salt and pepper, if you like, and set aside.
Filling
  1. Make the filling: Start your food processor and drop in the 2 cloves of peeled garlic. Process until finely chopped. Add the remaining filling ingredients and process until smooth, stopping to scrape down the sides of the bowl if necessary. Set aside.
Cheese Sauce
  1. Make the cheese sauce: Place all sauce ingredients into a blender and blend until completely smooth.
Assemble the Lasagna
  1. Preheat oven to 375F. Lightly oil a 2 1/2 to 3 quart oblong casserole dish. (Mine is 9.5 X 6.5 X 3 inches deep.) If you don't want to use oil, try lining the dish with parchment paper.
  2. Spoon about 1/4 cup of the spaghetti sauce into the bottom of the dish, just enough to coat the bottom. Spread half of the spaghetti squash over the sauce, and sprinkle with salt and pepper if you like. Drop the filling over the squash by large spoonfuls and then spread it out evenly. Arrange the mushrooms over the filling, followed by the spinach, if you’re using it. Pour half of the cheese sauce over the spinach and mushrooms. Add the remaining squash, smoothing it into an even layer. Pour the remaining spaghetti sauce over the top.
  3. Bake for 15 minutes. Then carefully, starting in the center of the pan, pour the remaining cheese sauce over the top, being careful not to splash the sauce onto the hot pan. Return to the oven and cook until the lasagna is bubbling all around the edges, about 30-40 more minutes. Remove from oven and allow to stand for at least 15 minutes–the sauce will thicken and the lasagna will be less watery the longer it stands. Serve warm.
