Description

An easy recipe for Instant Pot linguine with parmesan, spinach and mushrooms.


Ingredients

Scale
  • 1 Tbsp olive oil
  • 1 cup diced onion
  • 8 ounces sliced mushrooms
  • 1 Tbsp minced garlic
  • 2 1/2 cups water
  • Pinch of red pepper flakes
  • 1 Tbsp Better than Bouillon chicken base
  • 1 Tbsp white wine vinegar
  • 3/4 tsp Kosher salt
  • 1/2 tsp black pepper
  • 8 ounces uncooked linguine
  • 1 Tbsp cornstarch (if needed)
  • 1/2 cup heavy cream
  • 1 cup spinach
  • 1/2 cup shredded parmesan cheese

Instructions

  1. Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Add in the onion and mushroom. Saute for 4 minutes. Add in the garlic and saute for 30 seconds. 
  2. Pour in water and scrape bottom of pot so that nothing is sticking. Turn off pot.
  3. Stir in red pepper, chicken base, vinegar, salt and pepper. Break the pasta in half and lay it in the pot in a criss cross pattern. 
  4. Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 5 minutes. When time is up let pot sit for 5-10 minutes and then move valve to venting and remove the lid.
  5. Stir in the cream and spinach. If sauce needs to thicken up then make a cornstarch slurry by stirring 1 Tbsp cornstarch with 1 Tbsp cold water and turning pot to saute setting. Stir the slurry into the pot to thicken. 
  6. Turn off Instant Pot. Stir in the parmesan cheese. 
  7. Salt and pepper to taste. Serve and enjoy!
