Why This Recipe is Great:

  1. This zucchini alfredo lasagna is kid-friendly because the cheese hides the vegetables! This recipe layers ooey-gooey cheese with healthy veggies.
  2. It uses zucchini ribbons instead of pasta noodles.
  3. Zucchini noodles have a lighter and more refreshing taste and texture than regular pasta sheets. This can make your lasagna feel less heavy and more enjoyable, especially during warmer months.
  4. Zucchini noodles are easy to make with a spiralizer or julienne peeler, requiring no cooking beforehand. This can save time and effort when preparing your lasagna.
  5. This recipe is naturally gluten free. It also makes a great gluten free freezer meal!

Ingredient Notes:

  • Zucchini – I prefer to use large green zucchini. You can use other forms of summer squash as long as they are not too curvy to slice them.
  • Ricotta Cheese – You can use full-fat or reduced-fat ricotta cheese.
  • Alfredo Sauce- I include the directions below to make this lasagna’s homemade white alfredo sauce. I use heavy cream and do not recommend half and half.
  • Mozzarella Cheese – Adds even more flavor! Use full-fat or low-fat shredded cheese.
  • Parmesan Cheese – I used grated parmesan, but shredded also tastes great.
  • Seasonings – Dried basil and oregano.
  • Garlic – Use minced garlic cloves.
  • Olive Oil – Use extra virgin olive oil.
  • Meat – (Optional) You can use chicken or sausage or leave it meat-free to be vegetarian.

Tips For Success:

  • Use a vegetable mandolin so your zucchini is sliced thinly.
  • If you can, use full-fat ricotta. It makes this recipe creamy.
  • Periodically check your oven temperature. This inexpensive oven thermometer can tell you if your oven bakes at an accurate temperature.

How to Make Lasagna Alfredo:

Horizontally sliced zucchini slices on a plate.

Step 1: Slice your zucchini horizontally into ribbons. You can slice them by hand on a cutting board or use a mandolin slicer (pictured above.)

How to slice zucchini into noodles:

  1. Wash your zucchini. Cut off the ends.
  2. Place on a cutting board and cut off both ends.
  3. Use a knife to slice lengthwise slices thinly. A big zucchini should yield 7-8 zucchini noodles.
  4. You can also use a mandolin slicer. Use the grip that comes with it so you don’t accidentally slice your finger!

Step 2: Place a row of zucchini in a greased 9×13 casserole dish. Top with a layer of ricotta cheese.

Sauteing garlic and oil in a large pan.

Step 3: In a big pan, add the salted butter or olive oil and sauté the garlic for 2 minutes.

Adding parmesan to cream sauce.

Step 4: Slowly add cream, stirring until mixed in. Turn the heat to low and simmer for another 7 minutes. Add parmesan cheese and stir. Remove from heat.

Step 5: Add layers of the zucchini, ricotta, mozzarella, and alfredo sauce.

Step 6: Bake at 375º F for 30-40 minutes until it bubbles and the mozzarella on top melts and is slightly golden. Baking time will vary slightly depending on how tall you build your lasagna.

Recipe FAQ:

Can you use lasagna noodles instead of zucchini noodles?

You can use lasagna noodles. I like to make this recipe with no-bake lasagna noodles. Just be sure to use extra alfredo sauce if you use them so there is enough liquid for the noodles to soften.

How do you make this zucchini lasagna alfredo ahead?

Slice the zucchini and make the alfredo sauce ahead. You can either build the lasagna and refrigerate up to 3 days or assemble it and bake it up to 3 days later.

How long will this lasagna keep fresh?

This white lasagna will keep up to 4 days in the refrigerator. To reheat it, put it into the oven and bake at 325º F for 15-20 minutes, or microwave it.

How do you layer a lasagna?

My favorite way to layer a lasagna is to put down a base layer of noodles. Add some sauce and ricotta cheese. Sprinkle parmesan over the ricotta. Repeat these steps until you fill the casserole dish. Sprinkle the mozzarella over the top and bake.

How long do you bake a frozen lasagna?

If you froze this lasagna alfredo bake it later. Bake it at 375º F for 45-50 minutes.

    Good overall flavor- but I think next time I will grill or bake the zucchini noodles briefly and possibly add some basil and thickener to the sauce.
