    Person serving a piece of white sauce lasagna from a baking dish.

    I've always loved a good traditional lasagna made with marinara sauce, cottage cheese, and mozzarella, but I've found a new lasagna dish I've fallen in love with. I've made this white lasagna recipe four times this month, not only for my family to enjoy but I've also taken it to parties and potlucks and just like this chicken and rice casserole and this beef enchilada casserole, there are never any leftovers. It's a huge crowd pleaser!

    I attended a holiday party a couple of years ago and they served the most delicious white lasagna. The chef told me that white sauce lasagna is truly an authentic Italian recipe and originated in northern Italy. White lasagna is made with ricotta cheese, sliced mushrooms, chopped spinach, and Italian sausage mixed with a creamy Alfredo sauce layered on top of lasagna noodles. It was absolutely the best white lasagna I've ever had. I knew I had to go home and recreate my own version and after 6 attempts, I nailed it.

    Try pairing this with my Cheese Garlic Cauliflower Breadsticks or these Homemade Herb Ciabatta Rolls. I also love pairing it with my Romaine Salad with Vinaigrette Dressing, as well as my Summer Corn Salad! If you're a wine drinker, white sauce lasagna pairs extremely well with a nice fresh and crisp Chardonnay or Sauvignon Blanc. I love pairing this with Domaine Salmon Sancerre Sauvignon Blanc or this Rothchild Saga R Selection Prestige White Bordeaux.

    • White Sauce Lasagna Recipe

    Why This Recipe Works

    • Texture & Layering Matters More Than You May Think – a lot of lasagna recipes focus on the ingredients, but few discuss how finely chopping the sausage and mushrooms significantly improves texture and overall taste. Larger chunks can create an odd texture that's just not very palatable. That's why I chop the meat and mushrooms up super small...it allows for a creamier dish and everything blends together well both flavor and texture wise.
    • It yields lots of leftovers, stores really well in the refrigerator, and can easily be turned into a freezer meal!

    🛒 Ingredients You'll Need

    Multiple ingredients sitting on a counter to make a white sauce lasagna recipe.
    • Lasagna Noodles - Precooking the lasagna works best for this recipe. You can use oven-ready noodles to save time, but traditional noodles offer a more classic texture.
    • Ricotta Cheese - use the full fat version. It's way more creamy and brings a lot of richness.
    • Alfredo Sauce - after testing this recipe with many different Alfredo sauces, I found that the Buitoni Alfredo sauce tastes best and it saves some time. But, feel free to use a different store bought brand or make a homemade version. You can also make a Béchamel sauce recipe.
    • Mozzarella cheese - use whole milk mozzarella instead of part-skim. It will make the white lasagna more creamy. If you have time, grate a block of cheese for a more fresh flavor.
    • Parmesan Cheese - for best flavor results, grate a block of cheese. I use it the layering process, but I also like to sprinkle some on top for a golden, flavorful crust.
    • Spinach - use frozen spinach that has been thawed. Make sure you squeeze out all the water before layering.
    • Italian Sausage - this is a key ingredient to giving the lasagna a true Italian flavor. Either mild or spicy sausage can be used depending on what you like best.
    • Mushrooms - use fresh white or cremini sliced mushrooms.
    • Garlic - skip the jarred version and use fresh garlic cloves.
    • Onion - use a non-sweet onion, such as yellow or white.
    • Dried Herbs - I use Italian seasoning for the base herbs and then add in dried oregano and dried basil to give the lasagna for Italian based flavors.
    • Parsley - fresh chopped parsley is used as a garnish
    • Salt and Pepper - use as much as needed to add any additional flavor.

    📋 Variations

    • Meat Substitutions: Ground chicken, turkey, and beef can be used in this recipe, but they won’t provide the same bold Italian flavor as sausage. You can also use vegetarian meat!
    • Cheese Alternatives: Try substituting fontina, asiago, or gouda cheese in place of the mozzarella and ricotta.
    • Add Fresh Vegetables: Chopped eggplant and zucchini are great additional to this lasagna. If using them, add them at the same time you add in the mushrooms, onions, and garlic.
    • Make a Healthier Version: Try using part-skim ricotta and mozzarella to cut down on some of the fat. Swapping sausage for leaner ground turkey or chicken will also reduce the fat.

    🔪 Step-by-Step Recipe Instructions

    Person chopping and browning ground sausage.

    Step 1: Start by preheating the oven to 350°F. In a large skillet, ground the Italian sausage. When it's cooked all the way through, drain the grease and transfer the ground sausage to a cutting board. With a sharp knife, finely chop the cooked sausage and then set aside.

    🙋🏼‍♀️ Recipe FAQs

    Can I make white lasagna ahead of time?

    Yes! Assemble it up to 1 day in advance, cover with aluminum foil, and refrigerate. Bake on 350°F when ready to serve.

    Why is my white lasagna watery?

    It could be from not draining enough liquid from the spinach. Try using paper towels to press on the thawed spinach to ensure all the water is absorbed.

    Can I freeze white lasagna?

    Yes! Assemble per the instructions below and freeze it unbaked for up to 3 months, then bake straight from frozen, adding extra baking time as needed until done.

    Expert Tips

    1. It's super important to finely chop the ground Italian sausage and mushrooms. If they are too thick and chunky, it changes the taste and texture of the lasagna.
    2. When spreading the ricotta cheese and the Alfredo sauce, use a basting brush. This method will make your life a whole lot easier because ricotta is hard to spread.
    3. Store any leftovers in the container with a lid in the refrigerator for 3-4 days. Avoid covering the leftovers in the baking dish with aluminum because it will dry out faster.
    4. White lasagna tends to dry out faster than your traditional red sauce lasagna because it lacks the acidity from tomatoes and those really help retain moisture. To reheat white lasagna, place the pieces of lasagna in an oven safe dish and cover with aluminum foil. Heat on 325°F until warm all the way through.

    Notes

     
    • It's super important to finely chop the ground Italian sausage and mushrooms. It changes the taste and consistency of the dish if the sausage and mushrooms are too chunky.

    • Store any leftovers in the container with a lid in the refrigerator for 3-4 days. Avoid covering the leftovers in the baking dish with aluminum because it will dry out faster.
    • To reheat, place the pieces of lasagna in an oven safe dish and heat on 325°F until warm all the way through. Or, reheat in the microwave for 30-45 seconds until warm.
