About mussels

I believe in importance of diverse diet with well-rounded sources of protein, like chicken, beef, salmon. Each type of protein provides different minerals, nutrients and vitamins. And mussels are another incredible source of protein rich in iron, zinc, vitamin b12 and low in calories and fat.

It may be frowned upon to cook frozen mussels, but it’s incredibly hard to buy fresh seafood for those of us who live in rural areas away from the ocean.

We have tried many, many different frozen mussels. And I have to say, when it’s cooked right, they can be absolutely delicious! I only recommend frozen mussels in the shell though.

For food safety, most frozen mussels are pre-cooked. So it’s even easier to prepare it for a weeknight dinner!

How to thaw frozen mussels:

  1. Ideally, you want to thaw frozen mussels overnight in a fridge.
  2. In a pinch, you can place the vacuum sealed bag of mussels in a bowl with cool water for about 30 minutes, changing the water every 10 minutes or so.

How to cook frozen mussels:

While garlic white wine sauce is a classic choice for mussels, I keep things simple for a regular weeknight. 

  1. Sauté shallots and garlic slices in olive oil.
  2. Once shallots are soft, stir in a little chicken (or seafood) stock.
  3. Then add thawed mussels and cook, covered, until mussels are opened up and heated through. 
  4. Discard any unopened mussels and serve over pasta.

TIP: Be careful not to overcook the mussels, as they shrink in size and become tough. Perfectly cooked mussels should easily detach from the shell.

How many mussels do you serve per person?

Plan on 1 lb of mussels (in the shell) per person as a main entree, or 1/2 lb per person as an appetizer.

1lb of mussels yield 3-4oz of meat.
