It may be tough to recreate the juicy flavor of fresh-cooked fish, but it’s not impossible. Before you heat up the salmon dinner from last night and make your kitchen (or even worse, your office breakroom!) smell bad, read these five tips from chefs.
Salmon is a versatile and healthy protein that makes for delicious leftovers. However, reheating cooked salmon improperly can dry it out and ruin its tender texture. In this article, we’ll explore how to reheat leftover salmon the right way to keep it moist and flavorful.
Overview of Reheating Salmon
The key to reheating leftover salmon is using gentle indirect heat to warm it through without overcooking the delicate fish. Here are some tips
-
Use slower reheating methods like the oven or stovetop. Avoid the microwave.
-
Wrap the salmon in foil or parchment paper to retain moisture.
-
Reheat at 250-325°F until warmed through, 145°F internal temp.
-
Add a splash of water or oil to create steam and prevent drying out.
-
Take care not to overcook as salmon can turn flaky or rubbery.
Following these basic guidelines will ensure your leftover salmon stays succulent and delicious when reheated. Avoid common mistakes like high heat and uncovered cooking.
Why Salmon Dries Out Easily When Reheated
Salmon is a lean, delicate fish that can go from tender and juicy to dry and chewy quickly if care isn’t taken when reheating. A few reasons why salmon dries out easily:
-
Low natural fat content—Salmon has less protective fat than fish like tuna, which are higher in fat.
-
Delicate proteins – Salmon is made of fragile albumin proteins that denature easily.
-
Loose muscle structure – The loosely bundled muscle fibers separate when overcooked.
-
Tendency to overcook – It’s easy to exceed optimal temperature during reheating.
Knowing how salmon is impacted by heat helps avoid overcooking. Use gentler methods to preserve moisture and texture.
Best Ways to Reheat Leftover Salmon
Here are the top trouble-free ways to reheat salmon without drying it out:
Oven
Preheat oven to 250°F. Wrap salmon in foil and bake 7-10 minutes until warmed through. The gentle oven heat prevents overcooking while the foil pouch retains moisture.
Skillet
Heat oil in a nonstick skillet over low heat. Add wrapped salmon and cook 5 minutes per side. The fat keeps the salmon from sticking, and the low heat warms it without drying it out.
Poaching
Gently simmer salmon in poaching liquid like wine or broth until heated through, 5-7 minutes. The moist heat cooks the salmon evenly without drying it out.
Steaming
In a steamer pot, steam wrapped salmon 7-10 minutes until hot. The steam provides indirect heat that preserves moisture.
Sous Vide
Vacuum seal salmon and cook in a water bath at 115°F for 15 minutes until heated through. The precise temperature control prevents overcooking.
Things to Avoid When Reheating Salmon
Just as there are excellent ways to reheat salmon, there are also some big mistakes to avoid:
-
Microwaving – Creates hot spots that overcook the fish.
-
High heat – Dries out delicate salmon quickly.
-
Uncovered cooking – Leads to moisture loss.
-
Cooking too long – Can make salmon tough and chewy.
-
Direct grilling – Makes salmon stick to the grill and dry out.
Being mindful of these pitfalls will help you avoid ruining the taste and texture of leftover salmon when reheating.
How to Store Leftover Salmon Safely
Proper storage is key to keeping leftover salmon safe to reheat and eat later:
-
Let salmon cool completely after cooking, within 2 hours.
-
Transfer to an airtight container and refrigerate up to 3-4 days.
-
For longer storage, freeze salmon for 2-3 months. Thaw overnight in fridge before reheating.
-
Discard salmon with an off smell or gray/brown tint.
Follow these tips to store leftover salmon safely until you’re ready to reheat and enjoy it again.
Testing Salmon for Doneness
When reheating salmon, use these visual and temperature cues to test for doneness:
-
Flesh turns opaque and flakes easily with a fork.
-
Internal temperature reaches 145°F on a food thermometer.
-
Sauce or glaze is warm and bubbling.
Taking salmon’s temperature as it reheats prevents overcooking. The fish should be hot but still tender and moist.
Serving Reheated Salmon – Meal Ideas
Reheated salmon works great in all kinds of dishes:
-
Salmon salad with greens, vinaigrette and avocado.
-
Tacos with leftover grilled salmon, cabbage slaw and salsa.
-
Niçoise salad with reheated salmon, potatoes, green beans and olives.
-
Salmon fried rice or bibimbap bowl with quick-cooked veggies.
-
Smoked salmon omelette or frittata with cheese and veggies.
With a little creativity, leftover salmon can be reinvented into all sorts of tasty meals.
Common Questions About Reheating Salmon

Microwaving can overcook salmon. Use the oven or stovetop instead for the best results.
Should you add water when reheating salmon?
A splash of water or broth in the reheating dish helps add moisture and prevent drying.
Tips for the Best Reheated Salmon
Follow these tips for tasty reheated salmon every time:
-
Use gentle heat at 250°F or less.
-
Wrap in foil or parchment to retain moisture.
-
Reheat until flaky and 145°F internal temperature.
-
Add liquid to create steam and prevent drying.
-
Avoid microwaving to prevent overcooking.
-
Store properly refrigerated or frozen before reheating.
With care and the proper technique, you can enjoy leftover salmon that tastes just as amazing as the freshly cooked version!
How to Reheat Salmon Like a Chef
Never (ever!) reheat fish inside a microwave. This will dry out any fillet, even salmon, very quickly. It will also give off a bad, fishy smell. We know the efficiency of a microwave may appear tempting –– but trust us, it’s not worth it.
When reheating salmon, the fish is bound to lose some moisture. Rub a tablespoon of olive oil or the juice of half a lemon over the fish before putting it in the oven. Both methods help preserve the original flavor and freshness of the fish. Or, reheat salmon on a pan with a splash of water before turning on the burner.
