Ingredients

Scale

Pasta

  • 8 oz spaghetti

Protein and Vegetables

  • 12 oz Italian sausage, sliced
  • 2 cups fresh spinach
  • 4 cloves garlic, minced

Sauces and Fats

  • 2 tbsp butter
  • 1 tbsp olive oil

Cheese and Seasonings

  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated parmesan cheese
  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Cook the spaghetti: Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain the pasta and set aside.
  2. Brown the Italian sausage: Heat olive oil in a large pan over medium heat. Add the sliced Italian sausage and cook, stirring occasionally, until browned and fully cooked through, about 6-8 minutes.
  3. Sauté the garlic: Add the minced garlic to the pan with the sausage and cook for 1 minute, stirring frequently until the garlic becomes fragrant but not browned.
  4. Wilt the spinach: Stir in the fresh spinach and cook until wilted, about 2-3 minutes.
  5. Add the butter: Add the butter to the pan and stir continuously until melted and fully incorporated with the sausage and spinach mixture.
  6. Toss the spaghetti: Add the cooked spaghetti to the pan and toss thoroughly to coat the pasta evenly with the garlic butter, sausage, and spinach mixture.
  7. Melt the mozzarella cheese: Sprinkle the shredded mozzarella cheese over the pasta in the pan and allow it to melt slightly before serving.
  8. Finish with parmesan and seasoning: Remove from heat, then sprinkle grated parmesan cheese, salt, and black pepper to taste. Serve immediately while warm and cheesy.

Notes

  • Adjust the amount of garlic and cheese to suit your taste preferences.
  • For a spicier version, use hot Italian sausage instead of mild.
  • You can substitute spinach with kale or arugula for a different leafy green twist.
  • Leftovers can be refrigerated for up to 3 days and reheated gently on the stovetop or microwave.
