How to Make Vegetarian Mushroom and Spinach Lasagna
Preheat the oven to 180 °C (350 °F). This is crucial to ensure your lasagna bakes evenly for a deliciously cheesy crust.
Chop your vegetables. Finely chop the onion, mince the garlic, slice the mushrooms, and roughly chop the spinach. This will help everything cook evenly.
Saut the onion in a skillet with olive oil over medium heat for about 3-4 minutes until translucent. This creates the base flavor for your filling!
Add the minced garlic and cook for 1 minute until it becomes fragrant. Then stir in the sliced mushrooms, cooking until browned, which should take about 5-7 minutes.
Mix in the chopped spinach, cooking until just wilted or heated through. Season this mixture with basil, oregano, salt, and pepper for extra flavor.
Combine the cream of mushroom soup with milk in a bowl, mixing until smooth. If you desire, add a pinch of nutmeg for added warmth and depth of flavor.
Spread a layer of the soup mixture in a 9 13-inch baking dish, followed by a layer of no-cook noodles. Top this with the mushroom-spinach mix and dollops of ricotta. Repeat layers until your ingredients are used up, finishing with the soup mixture and cheeses on top.
Cover with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes until the top is golden and bubbling.
Cool the lasagna for about 10 minutes before slicing. This helps the layers set nicely for a beautiful presentation. Garnish with chopped parsley for a pop of color.
Optional: Serve with a side salad or garlic bread to complete your meal.
