Ingredients

  • 1 tbsp olive oil
  • 1 lb Andouille sausage, cut into ½ inch slices
  • 1 medium yellow onion, chopped
  • 4 cloves garlic, finely minced
  • 1 lb yellow baby potatoes, halved
  • 3 corn cobs, cut into 2-3 inch long segments
  • 1 ½ cups low-sodium chicken or vegetable stock
  • 2 tbsp salt-free Cajun seasoning
  • 1 tsp kosher salt
  • 1 tbsp Louisiana-style hot sauce
  • 1 lb frozen cooked shrimp, tails in tact

For the butter sauce:

  • 4 tbsp butter, melted
  • 1 tbsp lemon juice
  • 1 tsp salt-free Cajun seasoning

For garnish:

  • chopped fresh parsley
  • lemon wedges
  • additional melted butter

Instructions

  • Turn on your Instant Pot to saute mode and add oil. Once heated and shimmering, addthe sausage and brown on all sides, about 2-3 minutes.
  • Add onion and garlic. Saute until the onion is slightly softened and translucent, about 1-2 minutes.
  • Add in potatoes, corn, chicken broth, Cajun seasoning, salt, and hot sauce. Close the lid, select manual mode, and cook on high pressure for 5 minutes. Quick-release the pressure once the time is up.
  • Add the frozen shrimp on top of the other ingredients in the Instant Pot. Replace the lid,select manual mode, and cook on high pressure for 0 minutes. With 0 minutes, the timer will go off once the Instant Pot comes to pressure.
  • Prepare the butter sauce. In a medium-sized bowl, whisk together the melted butter, lemon juice, and Cajun seasoning. Top everything with the butter mixture and garnish with chopped parsley.
  • Serve immediately with lemon wedges and additional melted butter.

Notes

If you prefer to use a Cajun seasoning that already contains salt, omit the kosher salt in the recipe.
If you are using uncooked shrimp:
  • Completely thaw the shrimp.
  • Follow the recipe as is, but set the time to 1 minute instead of 0 minutes.
Dump everything on the table and eat it with your hands just like they do down south!
Store any leftovers in the fridge for 3-4 days. Reheat it in the oven for 10-15 minutes at 275° F in a foil-covered casserole dish with a bit of water over top.
Freeze the leftovers for up to 3 months. If you’re using frozen shrimp, you won’t be able to re-freeze it, but you can freeze the rest of the mixture.
