Step 1

Set the Instant Pot to Sauté and melt the butter. When the butter is beginning to foam, add the shallot and garlic and sauté until fragrant and lightly browned, 1 to 2 minutes.

Step 2

Place the mussels in the pot. Pour the broth and lemon juice over the mussels.

Step 3

Press Cancel. Secure the lid and set the steam release valve to Sealing. Press the Pressure Cook or Manual button and set the cook time to 3 minutes.

Step 4

When the Instant Pot beeps, carefully switch the steam release valve to Venting to quick-release the pressure. When fully released, open the lid. Discard any mussels that did not open during cooking.

Step 5

Carefully transfer the mussels to a serving bowl. Pour any remaining liquid from the pot over the mussels and sprinkle with the parsley. Serve and enjoy.
