How To Make White Sauce Lasagna

Here is a sneak peek of the steps involved to make vegetable lasagna with white sauce. Be sure to scroll to the bottom of this post for the full recipe.

Make the chicken mixture. Combine the carrots and broccoli in a bowl and set aside. In another bowl, combine the ricotta, egg, parmesan, mozzarella, and seasonings. Fold in the chicken.

Make the cream sauce. Melt the butter and whisk in the flour along with olive oil in a saucepan. Thicken until it starts to bubble. Slowly whisk in the half and half, cream cheese, and seasonings. Bring to a light simmer, stirring frequently, allowing the mixture to thicken. Fold in the mozzarella and parmesan cheeses.

Assemble the lasagna. Spread a thin layer of white sauce on the bottom of your baking dish. Layer with noodles. Cover evenly with the entire chicken mixture, then top that with spinach. Layer again with noodles. Spread a thicker layer of sauce on top of those noodles. Cover with chopped veggies. Layer again with noodles. Spread one final layer of sauce and top with remaining mozzarella cheese.

Bake and let rest. Bake at 400°F uncovered for 30 minutes. Rest for 10 minutes before serving.

Substitutions and Variations

Here are just a few ways you can really make this chicken alfredo lasagna your own:

  • Make it vegetarian. You can easily omit the chicken to make this dinner vegetarian-friendly! If you go this route, I recommend replacing the missing chicken with additional veggies to help bulk up the lasagna and stay filling.
  • Use freshly shredded cheese. It’s time to bust out the cheese grater. Trust me, freshly grated parmesan and mozzarella yield much more delicious, ooey gooey results than the pre-shredded stuff! With that in mind, though, you can substitute freshly grated cheese for pre-shredded if needed.

Tips for Success

I have a few tips and tricks below to help you make the best lasagna with white sauce.

  • Let it rest before serving. When you allow a lasagna to rest before serving, you greatly reduce the risk of burning your mouth! Plus, it gives the cheese and sauce time to cool and settle. If you slice into it while it’s still piping hot, the sauce will likely get all over your plate.
  • Use full fat cheese. When it comes to cream cheese and the other cheeses, try to avoid low-fat options. You’ll find that full fat cream cheese really yields the thickest and creamiest results here.
  • Remember to thaw your veggies. I like the simplicity of using frozen veggies! However, it’s important to remember to let the spinach, carrots, and broccoli thaw and drain of excess liquids before using them in this lasagna recipe.

Storage and Reheating Instructions

This easy white sauce lasagna makes the BEST leftovers! Once it’s totally cooled to room temperature, wrap the lasagna tightly with plastic wrap or cover it with a lid that’s fit for the pan. Store it in the fridge for up to 4 days. When you’re ready to serve it, you can pop it back in the oven or simply use the microwave – the choice is yours.

What to Serve with White Sauce Lasagna

This easy dinner recipe can stand all on its own! After all, it’s got veggies, protein, and carbs, so it’s fairly well-rounded. However, you can always add a nice veggie side to this hearty dish to round out your plate even more. Some of my favorites include Air Fryer Smashed Brussels Sprouts, Crazy Roasted Cauliflower and Roasted Parmesan Broccoli.
