White Lasagna Recipe With Ricotta Cheese: Creamy Spinach and Mushroom Layers

This white lasagna delivers creamy perfection with layers of ricotta, spinach, and mushrooms. A velvety béchamel sauce ties everything together for a dish that feels luxurious yet approachable.

I’ve refined this method to ensure each bite is rich and satisfying. The ricotta adds a light, fluffy texture, while the spinach and mushrooms bring earthy depth. Baking until golden creates a beautiful, bubbling finish.

The ricotta quality is paramount. Whole Foods or Trader Joe’s carry excellent full-fat options with superior texture. For mushrooms, cremini or baby bella offer the deepest earthy flavor—avoid button mushrooms as they lack complexity. The béchamel demands whole milk for richness; low-fat versions will not achieve the same velvety consistency.

No ricotta? Cottage cheese blended smooth works in a pinch, though texture differs slightly. For a nutty depth, fontina at half the quantity can replace some mozzarella. Fresh nutmeg is ideal, but pre-ground at one-fourth the amount suffices. If avoiding dairy entirely, cashew cream can substitute for béchamel, though this alters the dish’s character.

Assemble just before baking for best texture. Leftovers keep 4-5 days refrigerated, though the noodles soften over time. Freeze unbaked lasagna for up to 3 months—thaw overnight before baking.

Step-by-Step Instructions for White Lasagna with Ricotta Cheese

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Spinach and Mushroom Filling

In a large skillet over medium heat, sauté the 8 oz Cremini Mushrooms and 1 whole Shallot in a bit of olive oil until the mushrooms release their moisture and it evaporates, about 5-7 minutes. The mushrooms should be golden brown and the shallot translucent.

Add the 4 cloves Garlic Cloves and cook for 30 seconds until fragrant. Stir in the 10 oz Fresh Spinach in batches, allowing it to wilt down before adding more. Season with ½ tsp Salt and ¼ tsp Black Pepper. Transfer to a bowl and let cool slightly.

Once cooled, stir in the 2 cups Whole Milk Ricotta Cheese, ½ cup Parmesan Cheese, and ¼ tsp Nutmeg. This filling should be thick and creamy, with the spinach and mushrooms evenly distributed. Set aside while you prepare the béchamel.

Step 2: Make the Creamy Béchamel Sauce

In a medium saucepan, melt the ½ cup Unsalted Butter over medium heat. Once foaming, whisk in the ½ cup All-Purpose Flour to form a smooth paste (roux). Cook for 1-2 minutes, stirring constantly, until the mixture is light golden—this removes the raw flour taste.

Gradually whisk in the 3 cups Whole Milk, a little at a time, ensuring the mixture remains smooth. Bring to a gentle simmer and cook for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. Season with the remaining 1 tsp Salt and ¼ tsp Black Pepper.

Remove from heat and stir in the remaining ½ cup Parmesan Cheese. The sauce should be velvety and rich, with no lumps. Keep it warm while you assemble the lasagna.

Step 3: Layer and Assemble the Lasagna

Preheat your oven to 375°F. Spread a thin layer of béchamel sauce on the bottom of a 9×13-inch baking dish. Add a layer of 4 sheets Lasagna Noodles, slightly overlapping if necessary. Spread half of the ricotta-spinach-mushroom mixture evenly over the noodles.

Drizzle about ⅓ of the remaining béchamel sauce over the filling, then sprinkle ⅓ of the 2 cups Mozzarella Cheese on top. Repeat the layers: noodles, remaining ricotta mixture, another ⅓ of the béchamel, and another ⅓ of the Mozzarella Cheese.

Top with the final 4 sheets Lasagna Noodles, the remaining béchamel sauce, and the last ⅓ of the Mozzarella Cheese. The top should be evenly coated with sauce and cheese, with no dry spots.

Step 4: Bake to Golden Perfection

Cover the baking dish tightly with aluminum foil and bake for 25 minutes. This allows the noodles to soften and the layers to meld together without the top burning. Then, remove the foil and bake for an additional 15-20 minutes until the cheese is bubbly and golden brown and the edges are slightly crisp.

Let the lasagna rest for 10-15 minutes before slicing. This resting period is crucial—it allows the layers to set so they hold together when served. The lasagna should be creamy and rich, with each bite offering a balance of cheesy, spinach, and mushroom flavors.

Common Mistakes When Making Perfect Results

🔥 Overcooking the Ricotta Mixture

Heating the ricotta filling too long can make it grainy or dry, ruining the creamy texture of your white lasagna. Ricotta curdles easily when exposed to high heat for extended periods.

Fix: Gently fold ricotta with other ingredients off the heat. Only warm it briefly if needed, and avoid boiling.

🥘 Skipping the No-Boil Noodle Prep

Using regular lasagna noodles without pre-boiling can leave them hard and undercooked. Even no-boil noodles need extra moisture to soften properly in a white lasagna.

Fix: If using regular noodles, boil them for 2 minutes less than package instructions. For no-boil, ensure enough sauce and cover with foil while baking.

🌡️ Not Letting It Rest Before Serving

Cutting into lasagna straight from the oven causes the layers to slide apart, making a messy dish. The filling needs time to set for clean, beautiful slices.

Fix: Let the lasagna rest for at least 15-20 minutes after baking. This allows the cheese to firm up and the flavors to meld.

✨ Skimping on Seasoning

Ricotta and other mild cheeses can taste bland without proper seasoning. White lasagna lacks the boldness of tomato sauce, so every layer needs flavor.

Fix: Season the ricotta mixture generously with salt, pepper, garlic powder, and a pinch of nutmeg. Taste as you go to ensure depth of flavor.
