  • mandolin slicer


  • 1/2 Tbsp. avocado oil (or whatever oil you prefer)
  • 1 medium onion, chopped
  • 2 tsp minced garlic
  • 1 lb. lean ground turkey
  • 1 1/2 tsp. salt (plus extra for zucchini slices)
  • 1/2 tsp. pepper (plus extra for zucchini slices)
  • 1/2 tsp. dried oregano
  • 1 1/2 tsp. dried basil, divided (or 2 Tbsp. fresh basil)
  • 28 ounces crushed tomatoes (1 can)
  • 8 ounces tomato sauce
  • 2 bay leaves
  • cooking spray (or additional oil for zucchini)
  • 2 1/2 lbs. zucchini (4-5 medium sized zucchini)
  • 15 ounces part-skim ricotta
  • 1 egg
  • 1/8 tsp. nutmeg
  • 1/3 cup grated parmesan, divided
  • 2 cups shredded part-skim mozzarella
  • 1 Tbsp. chopped parsley (optional, or can sprinkle with extra fresh basil instead)


  • Heat oven to 400° F (205° C).
  • Heat oil in a large pan over medium heat. Add onion and sauté for 4-5 minutes to soften. Add garlic and cook a minute longer.
  • Add ground turkey and cook, breaking into small pieces with a wooden spoon while cooking.
  • Season turkey with salt, pepper, oregano, and half of the basil (if using fresh basil, wait and add during last 10 minutes of sauce simmer time).
  • Pour crushed tomatoes and tomato sauce into turkey, add bay leaf, and bring to a low simmer. Reduce heat and simmer for 30 minutes, stirring occasionally.
  • While sauce is simmering, cut ends off of each zucchini and use a mandolin slicer to slice zucchini into 1/8" thick slices.
  • Spray a baking sheet with cooking spray. Lay zucchini slices out in a single layer. Spray top side lightly with cooking spray and season lightly with salt and pepper. Place baking sheet in oven and roast for 15-20 minutes. When removing from oven, dab zucchini slices with a paper towel or clean kitchen towel if they appear watery.
  • While sauce simmers and zucchini bakes, mix ricotta, egg, half of parmesan, and nutmeg in a small bowl.
  • When sauce and zucchini slices are ready, remove bay leaves from sauce and ladle 1/3 of the sauce into the bottom of a 9x11" baking dish. Add layer of zucchini on top of sauce. Spread 1/2 of the ricotta mixture on top of zucchini slices. Sprinkle with 1/2 cup of mozzarella.
  • Repeat next layer with half of the remaining sauce, remaining ricotta, zucchini, and 1/2 cup of mozzarella. Top with remaining sauce, then mozzarella and parmesan.
  • Bake for 30 minutes until sauce is bubbling and cheese is melted. Let stand for about 10 minutes before serving.
