Easy Creamy Spinach and Mushroom Lasagna Recipe

Prep Time 25 minutes
Cook Time 45 minutes
Servings: 6 servings
Course: Main Course

Ingredients
  

  • 9-12 lasagna noodles (oven-ready optional)
  • 8-10 oz spinach (fresh or frozen, drained)
  • 8-12 oz mushrooms, sliced
  • 15 oz ricotta cheese
  • 1 egg
  • 2-3 cups mozzarella, shredded
  • ½ cup parmesan, grated
  • 2 cups milk
  • 2-3 tbsp butter
  • 2-3 flour
  • 2-3 cloves garlic
  • Salt, pepper, pinch of nutmeg

Method
 

  1. Step 1: Prep Everything First
    Preheat your oven to 375°F.
    Cook noodles if needed
    Slice mushrooms thin
    Drain spinach (seriously—don’t skip this)
    If spinach is watery, your lasagna will be too. No way around it.
  2. Step 2: Cook The Mushroom Filling
    Heat a pan with a bit of olive oil.
    Cook mushrooms for 6–8 minutes
    Let them release moisture—don’t rush
    Add garlic → quick stir
    Toss in spinach until wilted
    You’ll notice something here:
    The smell shifts from “just vegetables” to something warm, almost meaty. That’s your cue—it’s ready.
  3. Step 3: Make The Creamy Sauce
    Melt butter, add flour, stir for a minute.
    Then slowly add milk—keep whisking.
    Simmer until thick
    Add salt, nutmeg, parmesan
    You’re looking for a sauce that lightly coats a spoon. Not too thick. Not runny.
    Honestly, this step scares people… but it shouldn’t. It’s forgiving.
  4. Step 4: Mix The Ricotta Layer
    In a bowl:
    Ricotta
    Egg
    Parmesan
    Seasoning
    Mix until smooth. Done.
  5. Step 5: Layer Everything
    Here’s the rhythm:
    Sauce
    Noodles
    Ricotta
    Mushroom mix
    Mozzarella
    Repeat.
    Top layer = noodles + sauce + lots of cheese.
    It doesn’t have to look perfect. It’ll bake into something beautiful anyway.
  6. Step 6: Bake And Let It Do Its Thing
    Cover → bake 25–30 minutes
    Uncover → bake another 10–15
    Optional: broil for a golden top
    Your kitchen will smell… amazing. There’s no better word for it.
  7. Step 7: Let It Rest
    Wait 10–15 minutes before slicing.
    I know. It’s hard.
    But if you cut too early, it falls apart.
    Wait—and it slices clean, like a dream.
