Ingredients

Units Scale
  • 12 oz (340 g) spaghetti
  • 2 tbsp olive oil
  • 2 tbsp butter
  • 3 garlic cloves, minced
  • 1 onion, finely chopped
  • 8 oz (225 g) mushrooms, sliced
  • 1 red bell pepper, sliced
  • 1 yellow bell pepper, sliced
  • 1/2 tsp red pepper flakes (optional)
  • 1 cup heavy cream
  • 1/2 cup vegetable or chicken broth
  • 1/2 cup grated Parmesan cheese
  • 1 tsp dried Italian herbs (or a mix of basil, oregano, thyme)
  • Salt and black pepper, to taste
  • 2 tbsp fresh parsley, chopped (for garnish)

Instructions

  1. Cook spaghetti according to package instructions until al dente. Drain and set aside, reserving 1/2 cup pasta water.

  5. Pour in cream and broth, then stir in Italian herbs. Simmer for 3–4 minutes until slightly thickened.
  6. Stir in Parmesan cheese until melted and creamy.
  7. Add cooked spaghetti and toss to coat, adding reserved pasta water as needed for a silky sauce.
  8. Garnish with fresh parsley and serve warm.
