Low-Carb Lasagna (with Zucchini Noodles)

This cozy, lighter take on classic lasagna swaps wide pasta sheets for tender zucchini ribbons and builds layers of savory turkey, creamy ricotta, and melty mozzarella. It’s comforting, freezer-friendly, and easy to assemble—perfect for busy weeknights when you want something hearty without the heavy carbs. The flavors are familiar: garlicky tomato sauce, seasoned turkey, and a cheesy, slightly tangy ricotta layer. Using 3 large zucchinis gives you plenty of “noodles” to layer into a satisfying casserole that still feels like a proper lasagna.

Why you’ll love this version

• Lower in carbs thanks to zucchini noodles while preserving classic lasagna texture.
• Lean protein from 99% fat-free turkey keeps it light but filling.
• Quick to assemble — most of the work is browning and layering.
• Customizable — swap in different vegetables, cheeses, or a favorite jarred pizza sauce.

Ingredients

• 3 large zucchinis
• 1 tablespoon salt
• 2 tablespoons olive oil
• 1 pound ground 99% fat-free turkey
• 1 cup onion (roughly 1 small), diced
• 1 1/2 tablespoons garlic, minced
• 1 teaspoon salt
• Black pepper to taste
• 1 15-ounce container light or fat-free ricotta cheese
• 1 large egg
• 1 14-ounce jar pizza sauce
• 2 cups turkey pepperoni slices (roughly 48)
• 8 ounces light mozzarella cheese, grated
• 1/2 large green pepper, chopped
• 1/4 cup black olives, slivered
• 2 tablespoons Parmesan cheese, finely grated

Equipment

• Baking dish (approx. 9×13 inches or similar)
• Large skillet
• Mixing bowl
• Sharp knife and cutting board or a mandoline for slicing zucchini
• Paper towels or a clean kitchen towel

Prep and technique tips

• Slice the zucchini into thin, long ribbons—aim for 1/8–1/4 inch thick—so they bend easily and layer like pasta.
• Salt the zucchini and let it sweat for 10 minutes; then press out excess moisture. This keeps the lasagna from getting watery.
• Use a light hand when layering the sauce and ricotta so the casserole bakes evenly without becoming soupy.
• If you prefer extra browning, switch to broil for the final 1–2 minutes while watching carefully.

Step-by-step Instructions

Follow these rewritten steps for clear, reliable results. The order follows the original recipe logic but is phrased for clarity and ease.

1. Prepare the zucchini noodles. Trim the ends off the 3 large zucchinis. Using a sharp knife or mandoline, slice each zucchini lengthwise into thin ribbons about 1/8–1/4 inch thick. Lay the ribbons flat in a single layer on a few layers of paper towels or a clean kitchen towel. Sprinkle 1 tablespoon salt evenly over the zucchini ribbons and let them sit for 10 minutes so they release moisture. After resting, press or blot the ribbons firmly with additional paper towels to remove as much liquid as possible.
2. Cook the turkey and aromatics. Heat 2 tablespoons olive oil in a large skillet over medium heat. Add 1 cup diced onion (about 1 small) and sauté until softened and slightly translucent, about 3–4 minutes. Stir in 1 1/2 tablespoons minced garlic and cook for 30–45 seconds until fragrant. Add 1 pound ground 99% fat-free turkey to the skillet. Break the turkey up with a spatula and cook until it is no longer pink, about 6–8 minutes. Season with 1 teaspoon salt and black pepper to taste. Once cooked through, remove the skillet from heat.
3. Mix the ricotta layer. In a mixing bowl, combine the entire 15-ounce container of light or fat-free ricotta cheese with 1 large egg. Stir until smooth and evenly blended. Set this mixture aside.
4. Assemble the lasagna layers. Preheat your oven to 375°F (190°C). Spread a thin layer of the 14-ounce jar pizza sauce across the bottom of your baking dish to prevent sticking—about 1/3 to 1/2 cup will do. Arrange a single layer of zucchini ribbons over the sauce so the bottom is mostly covered. Spoon and spread about half of the cooked turkey mixture evenly over the zucchini layer. Drop spoonfuls of half the ricotta mixture across the turkey and gently spread, taking care not to tear the zucchini. Drizzle or spoon about one-third of the remaining pizza sauce over the ricotta.
5. Add pepperoni, vegetables, and cheese. Scatter roughly half of the 2 cups turkey pepperoni slices (about 24 slices) over the sauce. Evenly distribute half of the chopped 1/2 large green pepper and half of the 1/4 cup slivered black olives across the layer. Sprinkle a portion of the 8 ounces light mozzarella cheese (about one-third) over everything.
6. Repeat the layering. Add a second layer of zucchini ribbons to cover the first layers. Spoon the remaining cooked turkey over the zucchini, then spread the remaining ricotta mixture over the turkey. Drizzle another third of the pizza sauce across the top of the ricotta. Add the remaining turkey pepperoni slices, the rest of the chopped green pepper, and the remaining black olives. Top this layer with the remainder of the light mozzarella cheese.
7. Finish with sauce and Parmesan. Spread the final bit of pizza sauce over the top in an even layer. Sprinkle the 2 tablespoons finely grated Parmesan cheese evenly across the surface.
8. Bake until bubbly and set. Place the assembled dish in the preheated 375°F (190°C) oven and bake for 25–30 minutes, or until the cheese is melted, the sauce is bubbling around the edges, and the center is set. If the top is lightly browned but you want a crispier finish, switch the oven to broil for 1–2 minutes—watch it closely to prevent burning.
9. Rest, slice, and serve. Remove the lasagna from the oven and let it rest for 10–15 minutes. This helps the layers settle and makes slicing much cleaner. Use a sharp knife to cut into squares and serve warm. Leftovers keep well in the refrigerator for 3–4 days and reheat nicely in the oven or microwave.

Serving suggestions

• Serve with a crisp green salad dressed in lemon and olive oil to cut through the richness.
• Roasted or steamed green vegetables—like broccoli or asparagus—make a bright, simple side.
• For a lighter meal, pair a single serving with a side of pickled vegetables or marinated artichokes.

Make-ahead and storage

• To assemble ahead: build the lasagna in the baking dish, cover tightly with foil, and refrigerate for up to 24 hours. Add 5–10 extra minutes to the baking time if going straight from the fridge.
• To freeze: assemble but do not bake. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before baking; add 10–15 minutes to the baking time if still slightly cold.
• Leftovers can be stored in an airtight container for 3–4 days. Reheat covered in a 350°F (175°C) oven until warmed through, or microwave individual portions.

Ingredient swaps and variations

• Vegetarian: replace turkey with sautéed lentils or a plant-based ground substitute and add extra mushrooms for umami.
• Spicy: stir a pinch of red pepper flakes into the turkey while cooking or choose a spicy pizza sauce.
• Extra veggies: add thinly sliced mushrooms or spinach to the turkey mixture for more volume and nutrients.
• Cheese-free: omit mozzarella and Parmesan and increase ricotta slightly; consider adding nutritional yeast for a savory punch.

Notes

• Be mindful when salting the zucchini—some of that salt is absorbed into the squash and adds to the overall seasoning, so adjust the 1 teaspoon salt used when cooking the turkey if you prefer less sodium.
• Using lean turkey keeps the casserole from releasing excess fat as it bakes, which preserves texture and prevents a greasy finish.
