Servings: 6


  • Pressure Cooker / Instant Pot


  • 1 lb spaghetti noodles
  • 1 lb mushrooms
  • 4 cups low-sodium vegetable broth
  • ½ cup freshly grated parmesan cheese
  • ½ cup heavy whipping cream
  • ¼ cup fresh parsley chopped
  • 4 tbsp (divided) butter
  • 2 tbsp olive oil
  • 2 tbsp lemon juice about half
  • ½ tsp lemon zest
  • ½ tsp salt
  • ½ tsp black pepper


  • Clean, remove the stem and slice the mushrooms.
  • Set to sauté high. Add oil, 2 tbsp butter and wait for 1 minute or until the butter has completely melted.
  • Add mushrooms and cook for 5-6 minutes or until brown/caramelized. Add salt & pepper. Press the cancel button. Remove the mushrooms and place them in a bowl/plate. Set aside until ready to use.
  • Break the noodles in half. Place half of the spaghetti noodles on the bottom. Then layer the second half of the noodles the opposite direction (perpendicular). [I used pot size spaghetti noodles]
  • Pour the broth in the cooker. Use a wooden spoon/tongs to gently move the noodles around (this will prevent them from sticking together). Make sure that the noodles are submerged in the liquid.
  • Place the lid on. Pressure cook on high for 5 minutes with a 5 minutes natural release (exercise caution when releasing pressure from the cooker). Follow the manufacture instructions for releasing the pressure. Remove the lid. Use tongs and mix the noodles well (this will help to loosen the noodles).
  • Add cheese, heavy whipping cream, lemon juice, lemon zest, 2 tbsp butter and mix until everything is well combined. Add cooked mushrooms, parsley and mix.
  • Transfer a balanced portion of the pasta to a plate. Sprinkle with more Parmesan cheese. Season with salt & pepper (to taste). Garnish with parsley.

Serve immediately and enjoy!
