Turkey Vegetable Lasagna with Zucchini Noodles

I love lasagna.

What I don't always love is how I feel after eating three layers of pasta, cheese, and enough food to feed a small Italian village.

This turkey vegetable lasagna is one of my favorite ways to make a lighter, veggie-packed version of traditional lasagna without sacrificing flavor.

Instead of pasta noodles, we're using thinly sliced zucchini layered with seasoned ground turkey, tomato sauce, sautéed vegetables, creamy ricotta cheese, and fresh basil.

It's naturally gluten-free, packed with protein and vegetables, and still tastes like comfort food.

Because if my “healthy lasagna” tastes like steamed zucchini pretending to be dinner, I don't want it.

Why Use Zucchini Instead of Lasagna Noodles?

Zucchini works surprisingly well as a lasagna noodle alternative.

When sliced lengthwise into thin strips, it creates layers just like traditional lasagna noodles while adding vegetables and fiber to the meal. Zucchini also has a mild flavor, which means it takes on the flavors of the tomato sauce, garlic, herbs, and ricotta.

The biggest challenge?

Water.

Zucchini contains a lot of moisture, and if you skip the preparation step, you may end up with lasagna soup.

Still edible.

Not exactly what we were going for.

A High-Protein, Veggie-Packed Dinner

Ground turkey is one of my favorite lean protein sources because it's easy to cook and absorbs flavor really well.

For this recipe, I season the turkey with garlic powder, onion powder, oregano, salt, and pepper before adding tomato sauce. Then we layer in mushrooms, bell peppers, spinach, onion, and garlic.

This is the kind of recipe I love because you're not trying to choke down a side of vegetables after dinner.

The vegetables are already in the dinner.

You can also use grass-fed ground beef instead of turkey if that's what you prefer or already have in your refrigerator.

Ingredients:

• 1 pound ground turkey or grass-fed ground beef

• 3–4 large zucchini

• 1 24-ounce jar organic tomato sauce

• 8 ounces baby bella mushrooms, sliced

• 2 bell peppers, chopped

• 1 small onion, chopped

• 4–5 cloves garlic, minced

• 4 cups baby spinach

• 15 ounces ricotta cheese

• ¼ cup fresh basil leaves, plus more for garnish

• 1 teaspoon sea salt, divided

• ½ teaspoon black pepper, divided

• 1 teaspoon onion powder, divided

• 1 teaspoon garlic powder, divided

• 1 teaspoon dried oregano

• 1 tablespoon coconut oil

Directions:

1. Preheat the oven to 375°F.

2. Slice the zucchini lengthwise into thin strips using a mandoline or vegetable slicer.

3. Lay the zucchini slices on paper towels or clean kitchen towels. Allow them to sit while you prepare the remaining ingredients, then pat the zucchini thoroughly dry before assembling the lasagna.

4. Peel and mince the garlic. Chop the onion and bell peppers.

5. Heat the coconut oil in a large skillet over medium-high heat. Add the garlic and sauté for approximately 1–2 minutes.

6. Add the onion, bell peppers, and mushrooms. Season with ½ teaspoon sea salt, ¼ teaspoon black pepper, ½ teaspoon onion powder, and ½ teaspoon garlic powder.

7. Sauté until the vegetables begin to soften and the mushrooms are tender.

8. Add the baby spinach and continue cooking until the spinach is wilted.

9. Transfer the vegetable mixture to a bowl and set aside.

10. Using the same skillet, add the ground turkey. Season with the remaining ½ teaspoon sea salt, ¼ teaspoon black pepper, ½ teaspoon onion powder, ½ teaspoon garlic powder, and 1 teaspoon dried oregano.

11. Cook the turkey until it is completely cooked through and no longer pink. Ground turkey should reach an internal temperature of 165°F.

12. Add the tomato sauce to the cooked turkey and stir until completely combined.

How to Assemble the Lasagna

Spread a thin layer of the turkey and tomato sauce mixture across the bottom of a lasagna pan.

Add a layer of zucchini slices.

Spread the sautéed mushroom, onion, bell pepper, and spinach mixture over the zucchini.

Add another layer of zucchini.

Spread approximately 10 ounces of ricotta cheese over the zucchini and top with the fresh basil leaves.

Add another layer of zucchini and pour the remaining turkey and tomato sauce mixture over the top.

Finish with the remaining 5 ounces of ricotta cheese in dollops and garnish with additional fresh basil.

Cover the lasagna and bake for approximately 45 minutes, or until hot and bubbling.

Allow the lasagna to rest for 10–15 minutes before slicing.

Yes, you have to wait.

I know.

But this gives the lasagna time to set and makes it much easier to serve.

How to Keep Zucchini Lasagna from Getting Watery

This is the most important part of the recipe.

Get as much moisture out of the zucchini as possible.

After slicing the zucchini, let the strips rest on paper towels or clean kitchen towels and pat them thoroughly dry before assembling the lasagna.

And when I say pat them dry, I don't mean gently wave a paper towel in their general direction.

Dry the zucchini.

You can also lightly grill or roast the zucchini slices before assembling the lasagna if you want to remove even more moisture.

The other important step is allowing the finished lasagna to rest before cutting it.

If you pull it out of the oven and immediately attack it with a spatula because you're starving, the layers may slide apart.

Ask me how I know.

Easy Recipe Swaps

This recipe is incredibly easy to customize.

Use ground beef instead of turkey for a richer flavor. Add eggplant or additional spinach to the vegetable mixture if you have vegetables that need to be used.

If you prefer a dairy-free version, use your favorite dairy-free ricotta alternative.

You can also add shredded mozzarella or Parmesan if you tolerate dairy and want a cheesier lasagna.

There are no lasagna police.

Make it work for your body and your preferences.

💡 Dr. Stephanie's Tip: If you're trying to increase your protein intake, don't assume a meal is high in protein simply because it contains meat.

Look at how much protein is actually in each serving.

If you make a giant pan of lasagna with one pound of turkey and divide it into eight servings, you're not getting a massive serving of protein from the turkey alone.

Depending on your protein needs, consider using 1½ to 2 pounds of ground turkey or pairing your lasagna with another protein-rich food.

This is especially important for women in perimenopause and menopause who are trying to maintain or build muscle.

Yes, I just turned lasagna into a protein conversation.

You knew this was coming.

Healthy Comfort Food Can Still Taste Good

I don't believe healthy eating means eliminating every food you enjoy.

Sometimes I want traditional lasagna.

And sometimes I want a lighter version packed with protein and vegetables that still gives me the flavors I love.

This turkey vegetable lasagna is simple, naturally gluten-free, and loaded with zucchini, mushrooms, peppers, spinach, garlic, and fresh basil.

It's comfort food with significantly more vegetables and absolutely no sad salad required.
