Ingredients
  

  • 3 tablespoons olive oil divided, or as needed
  • 5 zucchini squash cut into 'noodles' using a spiral slicer or vegetable peeler
  • ¼ cup minced garlic
  • 1 16 ounce jar marinara sauce, or to taste
  • 1 7 ounce container 2% Greek yogurt
  • 1 pinch Italian seasoning or to taste
  • salt and ground black pepper to taste
  • ½ cup shredded mozzarella cheese

Instructions
 

  • Preheat oven to 425 degrees F (220 degrees C).
  • Heat 1 tablespoon oil in a large skillet over medium-high heat. Working in batches, saute enough zucchini to fit in the skillet with 1 teaspoon garlic until zucchini is slightly browned and softened, 3 to 6 minutes. Repeat with remaining olive oil, zucchini, and garlic. Transfer cooked zucchini mixture to a 9x13-inch baking dish.
  • Whisk marinara sauce, yogurt, Italian seasoning, salt, and black pepper together in a saucepan over low heat; cook and stir until sauce is warmed through, 5 to 10 minutes. Pour sauce over zucchini mixture in the baking dish. Sprinkle mozzarella cheese and a pinch of Italian seasoning over the top.
  • Bake in the preheated oven until cheese is bubbling, 20 to 30 minutes.
