Start by prepping the lobster tails for steaming. Use kitchen shears and cut a line down the inside of each shell. (I made the mistake of not doing this my first time and the lobsters curl up making them hard to cut when they are hot)
Add one cup of water in the Instant Pot Pressure Cooker.
Add 1 tablespoon of Old Bay seasoning to the water in the Instant Pot Pressure Cooker.
Place the trivet in the bottom of the Instant Pot Pressure Cooker on top of the water mixture.
Place 4 lobster tails shell side down.
Next, place the steamer basket on top of the first 4 lobster tails and add the remaining tails on the top of that steamer basket.
Lock the cover and make sure the vent is set to seal.
Now press the manual button and use the plus or minus buttons to adjust the minutes to 4 minutes. (Note: I used 4 minutes because the lobster tails were frozen)
It's important to know that your pressure cooker will take a while to heat up with frozen ingredients in it. I wanna say mine took about 10 to 15 minutes to heat up and get going.
The timer will switch to say "on" when it is heating up. Once it's heated, it will start to count down the minutes from 4 when it is steaming.
When the lobster tails are steaming in the Instant Pot Pressure Cooker, this is when I make the butter sauce.
To make the butter sauce, simply place a tablespoon of butter in a frying pan and cooking it for about 3 minutes until it turns brown. Add the remaining butter and a teaspoon of fresh minced garlic. Once it has completely melted add the remaining ingredients (lemon juice, pepper, and either cilantro or dill weed seasonings) to the butter mixture. Mix all the ingredients together and set aside.
Once the pressure cooker beeps telling you the time is up, turn it off and do a quick release of the steam. Careful not to place your hands on top of the button because that is where the steam comes out and it will burn you.
Once the steam has completely released, then unlock the lid and remove the lobster tails using kitchen tongs.
Serve the lobster tails immediately with the butter sauce.
Note: I use these same instructions even if I am only making 2 or 4 lobster tails at a time. The time doesn't change. If you are making fresh lobsters that have already thawed, I would only add 3 minutes to the pressure cooker time settings.
