Turn your instant pot on "sauté" mode. Once it is hot, add to your pot the butter, olive oil, garlic, and white onion. Stir occasionally until your butter has melted, and your onion has softened. This should take about 3 minutes.

Add to your pot your frozen shrimp. Stir well allowing the shrimp to cook, as well as taking the flavors of the other ingredients in the pot.

Once your shrimp has cooked, remove the shrimp from the bowl. Set aside.

Add to the pot your chicken stock, water, juice from the lemon, and noodles. Mix well to prevent the noodles from sticking together.

Place the Instant Pot lid on and close the seal. Set your Instant Pot to high pressure for 6 minutes.

Once your Instant Pot is done, manually release by using a towel or hot pad to open the seal. You do this by bringing the valve toward you.

Once the steam has completely released, open your Instant Pot. Add in your shrimp to the pot and noodles. Mix well.

You can top with more lemon juice, fresh parsley, salt or pepper to taste, and/or parmesan cheese
