Ingredients You’ll Need

Zucchini “Noodles”

• 3 large zucchini, about 2 to 2 ½ pounds total, sliced lengthwise into thin planks
  • I like medium-firm zucchini with smooth skin and minimal seeds.
  • Use a mandoline or a sharp chef’s knife for even slices.
• 1 teaspoon kosher salt, to draw out moisture

Meat Sauce Layer

• 1 tablespoon olive oil
• 1 pound lean ground turkey or lean ground beef
  • Ground turkey keeps it lighter, ground beef tastes a bit richer.
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 1 jar (24 ounces) marinara sauce
  • Choose a no sugar added brand like Rao’s or a store brand with simple ingredients.
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• ½ teaspoon crushed red pepper flakes, optional
• ½ teaspoon kosher salt, more to taste
• ¼ teaspoon black pepper

Ricotta Layer

• 1 ½ cups part skim ricotta cheese
• 1 large egg
• ½ cup grated Parmesan cheese
• 1 cup shredded part skim mozzarella cheese
• 2 tablespoons chopped fresh parsley or basil
• ¼ teaspoon kosher salt
• ¼ teaspoon black pepper

Topping

• 1 ½ cups shredded part skim mozzarella cheese
• ¼ cup grated Parmesan cheese
• 1 teaspoon Italian seasoning

Pantry Shortcuts & Substitutions

• Use pre shredded mozzarella and pre grated Parmesan to save time.
• Swap cottage cheese for ricotta if you prefer more protein and a tangier flavor.
• Use plant based crumbles instead of meat for a vegetarian version.
• Use homemade marinara if you already have some in the freezer.

Equipment List

• 9×13 inch baking dish
• Large skillet
• Cutting board and sharp knife or mandoline
• Mixing bowls
• Measuring cups and spoons
• Spatula and wooden spoon
• Paper towels or clean kitchen towels
• Aluminum foil

Tips & Tricks

• Slice zucchini into even, thin planks about ⅛ to ¼ inch thick so they cook through and layer easily.
• Salt zucchini slices and let them sit 10 to 15 minutes, then pat them very dry to avoid watery lasagna.
• Brown the meat deeply until you see golden bits on the bottom of the pan to build flavor.
• Use a thick marinara sauce or simmer it a few extra minutes so the lasagna sets nicely.
• Keep the ricotta mixture on the thicker side and avoid extra liquid so layers stay sturdy.
• Layer lightly and avoid overloading with sauce to prevent a soupy texture.
• Let the lasagna rest at least 15 minutes before slicing so it holds its shape.
• Use a sharp knife and a wide spatula to lift neat squares from the pan.
• Bake on a rimmed sheet pan to catch any bubbling sauce.
• Store leftovers in single serve containers for easy grab and heat lunches.

How to Make Healthy Zucchini Lasagna Recipe

Prep the Zucchini

1. Wash the zucchini and trim the ends.
2. Slice each zucchini lengthwise into thin planks about ⅛ to ¼ inch thick.
3. Lay the slices on a large sheet pan or cutting board.
4. Sprinkle both sides lightly with kosher salt and let them sit 10 to 15 minutes.
5. Blot both sides very well with paper towels or a clean towel until they feel dry.

Make the Meat Sauce

1. Heat olive oil in a large skillet over medium heat.
2. Add the diced onion and cook 3 to 4 minutes until it softens and turns translucent.
3. Stir in the garlic and cook 30 seconds until fragrant.
4. Add the ground turkey or beef and break it up with a wooden spoon.
5. Cook 6 to 8 minutes until the meat browns and no pink remains.
6. Season with salt, pepper, oregano, basil, and crushed red pepper flakes.
7. Pour in the marinara sauce and stir to combine.
8. Lower the heat and simmer the sauce 8 to 10 minutes so it thickens slightly.
9. Taste and adjust seasoning with more salt or pepper if needed.
10. Turn off the heat and set the sauce aside.

Mix the Ricotta Filling

1. In a medium bowl, add ricotta, egg, Parmesan, mozzarella, parsley or basil, salt, and pepper.
2. Stir until the mixture looks smooth and creamy.
3. Taste a tiny bit and adjust salt or pepper if needed.
4. Keep the bowl in the fridge while you set up the baking dish.

Preheat and Prep the Pan

1. Heat the oven to 375°F.
2. Lightly grease a 9×13 inch baking dish with olive oil or nonstick spray.
3. Place the dish on a rimmed baking sheet to catch any bubbling sauce.

Layer the Healthy Zucchini Lasagna Recipe

1. Spoon a thin layer of meat sauce into the bottom of the baking dish and spread it evenly.
2. Arrange a layer of zucchini slices over the sauce, slightly overlapping them to cover the bottom.
3. Dollop one third of the ricotta mixture over the zucchini and spread it gently.
4. Add another thin layer of meat sauce over the ricotta.
5. Repeat with another layer of zucchini, another third of the ricotta, and more sauce.
6. Finish with a final layer of zucchini, the last third of ricotta, and the remaining meat sauce.
7. Sprinkle the top with mozzarella, Parmesan, and Italian seasoning.

Bake the Lasagna

1. Cover the baking dish loosely with foil, tenting it slightly so it does not touch the cheese.
2. Bake 25 minutes covered.
3. Remove the foil and bake another 15 to 20 minutes until the cheese bubbles and turns golden in spots.
4. If you want extra browning, broil the top 1 to 2 minutes while you watch closely.
5. Remove the dish from the oven and let it rest 15 to 20 minutes before slicing.

Slice and Serve

1. Use a sharp knife to cut the lasagna into squares.
2. Slide a wide spatula under each piece and lift it out gently.
3. Sprinkle with extra fresh herbs if you have them.
4. Serve hot and enjoy that cheesy, veggie packed goodness.

What to Serve with Healthy Zucchini Lasagna Recipe

This Healthy Zucchini Lasagna Recipe pairs nicely with a big green salad with crisp lettuce, cucumbers, and a simple vinaigrette. Add a side of garlic bread or whole grain toast if you want something to soak up extra sauce. Steamed broccoli, roasted green beans, or a simple tomato cucumber salad also balance the richness. Serve it with sparkling water, flavored seltzer, or iced herbal tea for a fresh, family friendly meal.
