How to Choose the Best Salmon

There are a few kinds of salmon you can buy - King (rich and buttery and the most expensive), Sockeye (redder flesh, from the Northern Pacific), Coho (reddish-orange color, cheaper than King or Sockeye), and Pink (best eaten fresh the day its caught or as canned meat).

You can also buy wild-caught or farmed salmon. To check the sustainability level of your salmon, consult the Monterrey Bay Aquarium's Seafood Watch.

No matter which type of salmon you purchase, you should check for the following:

• Moist flesh - if the fish is dry it means it has been handled improperly or it's past its prime
• Bright flesh - you want the color of the fish to be deep, pale flesh indicates aging
• No brown spots - these indicate aging
• No fishy smell - salmon should have a light sea smell but should not smell fishy - if it smells strongly it is past its prime

How to Know When Salmon Is Done Cooking

Usually, a salmon fillet will take from 6 to 8 minutes to cook fully (unless it’s cooking in a sauce). Salmon will go from red/raw to opaque/pink as it cooks.

Salmon that is perfectly cooked through will flake, but still maintain moisture. The USDA recommends salmon be cooked to a temperature of 145 degrees Fahrenheit (you can check this with an instant-read thermometer).

Side Dishes to Serve with Salmon

Salmon pairs well with so many side dishes - it’s mellow flavor works with many vegetables, legumes, and salads. Here's a whole post on side dishes for salmon. Some of my favorite sides to pair with salmon are:

• Sauteed sugar snap peas
• Grilled baby bok choy
• Brown butter radishes
• Roasted or grilled asparagus
• Fennel au gratin
• Roasted baby potatoes
• Brown or white rice

Tips for this Spinach Stuffed Salmon Recipe

A few tips for this recipes, I would definitely recommend baking the salmon on a rimmed baking sheet - because there might be some moisture loss from the spinach and you don’t want that to spill onto the heating element in the oven.

You can also make it in a casserole dish. Another thing to consider would be using a silpat when baking your salmon - if you like salmon skin this will make it easier to keep the skin intact to serve with the fillet.
