  • 6 oz manicotti shells
  • 2 tbsp extra virgin olive oil
  • 2 tbsp minced garlic
  • 2 cups heavy whipping cream
  • 1 cup grated parmesan cheese divided
  • 1 tbsp cajun seasoning divided
  • 1/2 tsp Italian seasoning
  • pinch of red pepper flakes
  • pinch of ground nutmeg
  • 1 cup ricotta cheese
  • 2 cups fresh spinach
  • 1/2 cup diced onion
  • 1 cup shedded mozzarella cheese
  • parsley for garnish


  • Preheat oven to 350 F degrees.
  • Cook the manicotti according to the instructions on the box and set aside separately to bring back to room temperature.
  • Add olive oil to a large pan over medium high heat. Once melted, add garlic and cook for 30-60 seconds making sure not to overcook and cause burning.
  • Add heavy cream, ½ cup of parmesan cheese, ½ tablespoon of cajun seasoning, Italian Seasoning, pinch of red pepper flakes, and pinch of ground nutmeg and stir to mix together. Bring cream sauce to a boil then reduce heat to low and simmer for 5-7 minutes to thicken. Once thickened, remove from heat and pour into a large baking pan and set aside.
  • Next in a separate medium sized bowl, add ricotta cheese, spinach, onion, remaining parmesan and remaining cajun seasoning and stir together to combine well.
  • Stuff room temperature manicotti with spinach mixture and add to the bottom of the sauced baking pan.
  • Cover with mozzarella cheese and bake for 20 minutes or until the cheese has completely melted and is bubbling. Remove from the oven. Allow to cool for 10-15 minutes, garnish with parsley and serve.


To store leftovers, transfer the manicotti to an airtight container or cover the original baking dish with plastic wrap. The leftovers will keep for 3-5 days refrigerated.
For easy reheating, place your desired portion on a microwave-safe dish or plate and microwave at 30 second intervals until heated through. Alternatively, you can reheat the leftovers in the original baking dish in the oven for 15-20 minutes.
