🧾 Ingredients

For the Creamy Filling:

  • 2 tbsp olive oil
  • 1 large onion, finely chopped
  • 3 cloves garlic, minced
  • 10 oz mushrooms, sliced (cremini or button work great)
  • 10 oz fresh spinach leaves
  • Salt and black pepper, to taste
  • 2 cups ricotta cheese
  • ½ cup grated Parmesan cheese
  • 1 egg (optional, for a firmer filling)
  • Pinch of nutmeg (optional but recommended)

For the White Sauce:

  • 4 tbsp butter
  • 4 tbsp all-purpose flour
  • 3 cups milk (preferably whole milk)
  • ½ tsp salt
  • ¼ tsp ground black pepper
  • ½ cup grated mozzarella or Gruyère cheese (optional for extra richness)

For Assembly:

  • 9–12 lasagna noodles, cooked according to package directions or use no-boil noodles
  • 1½–2 cups shredded mozzarella cheese (for topping)
  • Fresh basil or parsley, for garnish

👩‍🍳 Instructions

Step 1: Prepare the Spinach & Mushroom Mixture

  1. Heat olive oil in a large skillet over medium heat.
  2. Add chopped onion and sauté for 3–4 minutes until translucent.
  3. Stir in the garlic and cook for another 30 seconds.
  4. Add the sliced mushrooms and sauté until browned and most of their moisture has evaporated—about 8–10 minutes.
  5. Add fresh spinach in batches, letting it wilt before adding more. Cook until all spinach is wilted.
  6. Season with salt, pepper, and a pinch of nutmeg.
  7. Set aside to cool slightly.

Step 2: Make the Ricotta Layer

In a mixing bowl, combine ricotta, Parmesan, and the optional egg. Mix until smooth. Once the spinach-mushroom mixture is cool enough, stir it into the ricotta mixture.

Step 3: Make the White Sauce (Béchamel)

  1. In a saucepan, melt butter over medium heat.
  2. Whisk in flour and cook for 1–2 minutes to form a roux (a paste-like consistency).
  3. Gradually whisk in the milk until smooth.
  4. Bring to a gentle boil, then reduce to a simmer and cook for 5–7 minutes until the sauce thickens.
  5. Stir in salt, pepper, and optional shredded cheese. Remove from heat.

Step 4: Assemble the Lasagna

  1. Preheat oven to 375°F (190°C).
  2. Spread a thin layer of white sauce on the bottom of a greased 9×13-inch baking dish.
  3. Add a layer of noodles.
  4. Spread ⅓ of the spinach-ricotta mixture.
  5. Pour over ⅓ of the white sauce.
  6. Repeat layers two more times: noodles, filling, sauce.
  7. Finish with noodles, remaining white sauce, and a generous topping of shredded mozzarella.

Step 5: Bake

  1. Cover with foil (tent it so it doesn’t stick to the cheese).
  2. Bake for 25 minutes covered, then remove foil and bake for an additional 15–20 minutes until bubbly and golden.
  3. Let rest 10–15 minutes before slicing.

💡 Tips for the Best Creamy Lasagna

  • Drain the spinach: If your spinach releases a lot of moisture, press it with a spoon or pat it dry before mixing with ricotta.
  • Add herbs: A little fresh thyme or Italian seasoning goes beautifully with mushrooms and spinach.
  • Use fresh pasta sheets if you want an extra luxe texture—they don’t need boiling.

🥗 What to Serve With It

This lasagna is rich and comforting on its own, but it pairs beautifully with:

  • A crisp green salad with vinaigrette
  • Roasted vegetables (think carrots or zucchini)
  • Garlic bread or herb focaccia
  • A glass of chilled white wine like Pinot Grigio or Chardonnay

🧊 Storage & Freezing

  • Fridge: Store leftovers in an airtight container for up to 4 days. Reheat in the oven or microwave.
  • Freezer: Freeze unbaked or baked lasagna. Wrap tightly and store up to 3 months. Thaw overnight in the fridge and bake as directed.
