Spinach & Mushroom Lasagna (Vegetarian, Gluten, Grain Free & Low Carb) From Above

Lasagna is such a comforting, warming and super delicious dish. It’s always my go to when I want to make something in a big batch, that tastes amazing and just gets better the longer it gets to sit in the fridge. And the best thing is that you can vary it endlessly using different ingredients, vegetables, proteins and cheeses. Since I don’t eat gluten and Im not a huge fan of pasta I always make my lasagnas using zucchini instead of lasagna sheets. It makes the lasagna lighter and won’t put you in a food coma after eating a piece, but still doesn’t compromise the gooey and delicious taste. Kind of combining the best of two worlds! Even my pasta loving boyfriend love love love my zucchini based lasagnas! This lasagna is a vegetarian one made with mixed mushrooms, spinach, Creme Fraiche, some wine (optional), feta cheese and yellow cheese. It is so incredibly creamy, tasty and delicious but also has a light and fresh feeling to it. This lasagna is perfect to make serve for lunch or dinner or to make for meal prep purpose, preferably in a double batch. This lasagna is both vegetarian, gluten, grain free and low carb.

A few tips:

  • Preferably slice the zucchini using a mandolin to make sure the slices are equally thick.
  • You want thin slices but not too thin, you still want to be able to taste and feel them when eating the lasagna. Therefore I used thickness 3 out of 4 on my mandolin.
  • I used mixed mushrooms for this lasagna (button mushrooms, forest mushrooms and portobello) but you can use any mushrooms that you like or can find in the store.
  • I used fresh spinach when making this lasagna, but you can also use frozen spinach. Make sure to thaw the spinach in advance and then squeeze out the excess water before adding it to the pan.
  • I added a bit of white wine to the mushroom spinach mixture because I like the taste it adds. But you can omit it if you want.
  • You can layer this lasagna in three or four layers, depending on how big your pan is.
  • Bake the lasagna for approximately 25-35 minutes. If the cheese isn’t golden brown when you’ve baked it for 25-35 minutes turn on the broiler and bake for another 1-3 minutes. But be sure to check on the lasagna so it doesn’t burn.
  • This lasagna is good to store in the fridge for up tp 5 days.
  • You can also freeze the lasagna in portion sizes and then let it thaw over night or defrost it in the microwave. I prefer to reheat my lasagna in the oven on low heat.
