I discovered oyster mushrooms a long time ago and they have been a regular ingredient in my kitchen. Meaty, satisfying and flavorful, they are especially amazing when sauteed over medium-high heat with butter. I use them as a side dish for steaks, put them on homemade hamburgers or mix them in pasta and rice dishes. They can wonderfully compliment a variety of dishes and enhance their flavors.
Today I decided to make a meatless lasagna, using oyster mushrooms as a substitute for meat, and adding ricotta. I expected my ricotta and oyster mushroom lasagna to turn out very good, but it pleasantly surprised me. Flavorful, tender, and filling, it tasted terrific. Meaty oyster mushrooms turned out a to be a good substitute for beef that I normally use, they almost had a similar texture. Addition of caramelized onions – sweet, savory and flavorful – made the lasagna even more flavorful. I also enjoyed the smoothness of creamy homemade ricotta cheese in this lasagna. If you want try it, it’s fairly easy to make, and can be made in advance.
Preparation time for ricotta and oyster mushroom lasagna, unlike meat lasagna, is fairly short. Prepare your lasagna noodles and set aside. In a bow, mix ricotta cheese with salt, eggs, dill and parsley. Both dill and parsley can be optional, depending your taste preferences.
Saute onions first over medium heat until golden brown for about 8-10 minutes and transfer into a bowl.
Then saute your mushrooms in the same skillet. You want to start sauteing them over high heat first, for about 5-6 minutes to let the water evaporate as quickly as possible – mushrooms release a fair bit of water. Otherwise they will cook in water without getting a nice, deep golden brown crust.
Next, turn the heat down to medium, add back onions and continue cooking for another 2-3 minutes.
Now that all the prep work is done, we are ready to assemble the lasagna. Spread about 1 tablespoon ricotta mix on the bottom of a 8 x 8 inch baking pan. If you don’t have one of a similar size , use a bigger one. If it’s much bigger, you may want to scale the recipe proportionately.
Layer noodles, followed by ricotta filling, followed by mozzarella cheese, and finishing with Parmesan cheese.
Repeat another layer.
Cover with foil and bake for 25 minutes at 375F. Remove foil and bake for another 20 minutes. Let the lasagna cool for 10-15 minutes and serve.
