Ingredients
  

  • 2 tbsp butter
  • 3 tbsp olive oil divided
  • 5 hot italian sausage links
  • Salt & cracked black pepper to taste
  • 3 green zucchini diced into half in pieces
  • ½ a large eggplant chopped lengthwise & diced into half in pieces
  • 1 onion chopped
  • 7 – 8 garlic cloves chopped
  • 1 tbsp Italian seasoning
  • 1 tbsp garlic powder
  • ½ tsp crushed red pepper
  • 1 tbsp tomato paste
  • 28 oz can crushed tomatoes
  • 4-5 fresh basil leaves ripped up
  • 1 cup grated pecorino romano divided
  • 2 cups whole milk shredded Mozzarella
  • ¼ cup fresh parsley chopped

Instructions
 

  • In a pan, heat up in butter and 2 tbsp of olive oil. Then remove the casings from the sausage and add the sausage to the pan. Begin mashing the sausage up with a meat masher and once it’s all mashed up add in salt & cracked black pepper. Saute that on medium – medium high heat until the sausage is browned. Once the sausage is browned remove it from the pan and set it aside on a plate.
  • In that same pan, add in the zucchini, eggplant, onion, garlic, salt, cracked black pepper, Italian seasoning, garlic powder, crushed red pepper flakes, and 1 tbsp of olive oil. Saute that for about 10 minutes or until the veggies are golden and soft (if the veggies are looking to dry add in more olive oil).
  • Add in the tomato paste and brown it for 2-3 minutes. Next, stir in the crushed tomatoes and bring the pan to a boil. Add in the ripped up fresh basil, more salt & cracked black pepper, and ½ cup of grated pecorino romano. Then, add the ground sausage back into the pan. Stir everything together, lower the pan to a simmer, and let everything simmer together for about five minutes.
  • Transfer that sausage veggie mixture into a 9×13 baking dish and smooth it out. Sprinkle over a ½ cup of grated pecorino romano, shredded mozzarella, and fresh parsley. Bake it in the oven at 375° for 15 minutes.
