A luxuriously creamy mushroom and spinach lasagna that transforms humble vegetables into an elegant meat-free main dish. Each layer combines earthy mushrooms, tender spinach, and three complementary cheeses, all enveloped in a silky homemade white sauce that makes every bite memorable.
After years of making traditional meat lasagna, I discovered this vegetarian version during a cooking class in Italy. The instructor taught me that the key to perfect texture lies in properly cooking the mushrooms until they release their moisture. Now my family actually prefers this version to the classic meat recipe.
Essential Ingredients
- Mushrooms: Choose firm, fresh cremini for best flavor
- Spinach: Fresh provides better texture than frozen
- Lasagna Noodles: Traditional or no-boil both work well
- Ricotta: Full-fat gives creamiest results
- White Sauce: Starts with good quality butter
- Three Cheeses: Each adds distinct flavor and texture
Detailed Instructions
- Step 1:
- Begin by preparing all ingredients before assembly - mise en place makes the process smoother.
- Step 2:
- Cook mushrooms in batches to prevent steaming - they should get golden brown.
- Step 3:
- Make white sauce gradually, whisking constantly for smoothness.
- Step 4:
- Let sauce cool slightly before assembly to prevent cheese from melting too quickly.
- Step 5:
- Layer ingredients evenly, spreading each component to the edges.
- Step 6:
- Press down gently on noodles to remove air pockets.
- Step 7:
- Cover edges of foil with cooking spray to prevent sticking to cheese.
- Step 8:
- Watch final browning carefully - golden spots should appear but not burn.
- Step 9:
- Allow proper resting time for clean slices.
- Step 10:
- Serve at just-warm temperature for best flavor.
