Instant Pot Spinach Mushroom Pesto Pasta

  • Prep Time: 10 minutes
  • Cook Time: 4
  • Total Time: 14 minutes
  • Yield: 3-4 servings 1x


An easy, tasty and fast meatless meal of your favorite type of pasta enveloped in a basil pesto sauce with plenty of sauteed mushrooms and spinach. Add bites of chicken if you prefer. 


  • 1 Tbsp canola oil
  • 8 oz (1/2 lb) white button mushrooms, chopped
  • 1/2 tsp kosher salt
  • 1/2 tsp black pepper
  • 8 oz uncooked orecchiette pasta (or other pasta of your choice)
  • 1 3/4 cups water
  • 5 oz fresh spinach
  • 1/2 cup pesto
  • 1/3 cup grated mozzarella cheese or parmesan cheese (optional)


  1. Turn your Instant Pot to the saute function. While it heats up, chop up your mushrooms. When the display reads HOT add in your oil. Then add in your mushrooms, salt and pepper and saute for about 5 minutes. Add in your pasta and water.
  2. Cover and secure the lid into place. Make sure valve is set to sealing. Set the manual/pressure cook button to 5 minutes (if cooking with another type of pasta read my note below). When the time is up move the valve to venting. Remove the lid.
  3. Stir in the spinach. And then stir in the pesto and cheese. If there is too much liquid you can use a cornstarch slurry to thicken the sauce by mixing 1 Tbsp of cornstarch with 1 Tbsp of water and then stirring the mixture into the pot.
  4. Scoop the pasta into serving dishes and enjoy! Store leftovers in an airtight container in the refrigerator for up to a week.


This recipe can easily be doubled for a larger group of people. Double all the ingredients and keep the time the same.

To determine how long to cook your choice of pasta look at the back of the box. If the recipe reads boil for 12 minutes you will divide that number by 2 and subtract 1. So for 12 minutes on the stove it would be 5 minutes in the Instant Pot. Thin spaghetti will take less time and more hearty noodles like these orecchiette will take longer.

If you’d like to add chicken to this recipe, you can. You can add in either cooked or uncooked chunks of chicken breast in with everything else at the beginning. It will cook at the same rate as the pasta as long as it is cut up into bite size pieces.

I used my 6 quart Instant Pot Duo 60 7 in 1*.
