How Long to Smoke Salmon at 225°F for Perfectly Cooked Fish

As someone who grew up in the Pacific Northwest, smoked salmon has always been one of my favorite foods. Every year, my family would catch wild salmon and spend a day smoking it over alderwood. The sight and smell of the fish cooking over the fire pit brings back fond memories. These days, I like to recreate that experience by smoking salmon at 225°F in my smoker. It may take a few hours, but the result is always worth it. The salmon comes out with a lovely golden color, irresistibly tender texture, and wonderfully smoky flavor.

In this article, I’ll share everything you need to know about how long to smoke salmon at 225°F. You’ll learn the ideal internal temperature, smoking times per pound, the importance of brining, and tips for maximizing flavor. With this guide, you’ll be able to make restaurant-quality smoked salmon right at home. So let’s get started!

The Optimal Smoking Temperature and Internal Temperature for Salmon

When it comes to smoking salmon, the target smoker temperature should be 225°F. This relatively low cooking temperature allows the salmon to smoke for hours, infusing it with flavor all the way through. The collagen in the salmon breaks down at this temp, leading to a lush, velvety texture.

You’ll want to smoke the salmon until it reaches an internal temperature of 145°F. This ensures any potential bacteria are killed while still retaining moisture. Salmon cooked to 145°F is safe to eat yet still tender and juicy.

Smoking the salmon low and slow at 225°F gives you the classic combination of smoky, salty, and slightly sweet flavors. The fish develops a lovely reddish-orange hue on the outer layer too.

Approximate Smoking Times Per Pound at 225°F

So how long exactly should you smoke salmon at 225°F? The smoking time can vary based on the size and thickness of the fillets. Here are some general guidelines:

  • For a 1-pound fillet, smoke for approximately 3-4 hours
  • For a 2-pound fillet, smoke for approximately 5-6 hours
  • For a 3-pound fillet, smoke for approximately 6-8 hours

You can see that, in general, smoking times are about 1.5 – 2 hours per pound when hot smoking salmon at 225°F.

However, it’s impossible to rely on time alone. The thickness and shape of the fillet impacts how quickly it cooks. Taller fillets may take longer to reach 145°F in the thickest part of the meat. The only way to guarantee perfect doneness is to use an instant-read meat thermometer.

Why It’s Critical to Use a Meat Thermometer

While the cooking times above offer a rough estimate, salmon can sometimes cook faster or slower. The thickness of the fillet, moisture content, and proximity to the smoker’s heat source all impact the cooking rate. Relying on time alone risks over or undercooking.

This is why I always recommend using an instant-read meat thermometer when smoking salmon at 225°F. Insert the probe into the thickest part of the fillet and verify it reaches 145°F internally. This guarantees the salmon has cooked through fully and evenly without any raw spots.

A good instant-read thermometer takes the guesswork out of salmon smoking times. You’ll never have to cut into the fish prematurely or worry about serving undercooked salmon. It offers peace of mind that your salmon is perfectly and safely cooked.

Brining Is Essential for Moist, Flavorful Salmon

Before smoking salmon, it’s highly recommended to brine the fillets for added moisture and flavor. Brining involves submerging the salmon in a saltwater solution before smoking. A basic brine is made by mixing 1 cup kosher salt with 1 gallon of water until fully dissolved.

Brining salmon before smoking accomplishes a few things:

  • Infuses the salmon with seasoning, enhancing the natural flavor
  • Helps the fish retain moisture instead of drying out
  • Denatures proteins for a tender, silky texture
  • Inhibits bacteria for longer shelf life

After brining for 8-12 hours, simply pat the fillets dry and apply any additional seasoning. The brined salmon is now ready for several hours of aromatic smoking.

Brining is a simple step that pays off in the final texture and taste. Even just 8 hours of brining makes the salmon noticeably more moist and flavorful after smoking.

Smoking Tips to Maximize Flavor

To get the most out of smoking salmon at 225°F, follow these tips for infusing rich, smoky flavor in every bite:

  • Use a high-quality alder, apple, or cherry wood for mild, fruitwood smoke flavor. Stay away from harsh mesquite or hickory.
  • Place a disposable aluminum foil pan under the salmon to catch drippings. This prevents smoldering drips from ruining the smoke flavor.
  • Resist opening the smoker frequently. This lets heat and smoke build consistently during the long cooking time.
  • Brush the salmon with pure maple syrup during the last 30 minutes for subtle sweetness.
  • Let the smoked salmon rest for 30 minutes before slicing. This allows juices to redistribute evenly.

With patience and these flavor-boosting tips, your home-smoked salmon will be incredible!

Frequently Asked Questions About Smoking Salmon at 225°F

How do you know when smoked salmon is done at 225°F?

Use an instant-read thermometer to check for an internal temperature of 145°F. This ensures the thickest part of the salmon is fully cooked through. Relying solely on smoking times risks under or overcooking.

Is there a difference between hot smoked and cold smoked salmon?

Yes, there are some key differences. Hot smoked salmon cooks at temperatures between 150 – 250°F until reaching safe internal temperatures. Cold smoked salmon never exceeds 90°F, essentially curing the fish. Hot smoked salmon has a flaky, opaque appearance while cold smoked is translucent.

Can you eat hot smoked salmon right away?

Yes, hot smoked salmon cooked to 145°F is safe to eat right away since the heat from smoking kills any bacteria. Letting it rest makes slicing easier. Cold smoked salmon needs to be fully cured before consuming.

What wood is best for smoking salmon?

For salmon, milder fruitwoods like alder, apple, and cherry are recommended. The subtly sweet smoke complements the flavor of the fish. Avoid harsher woods like hickory or mesquite which overpower salmon.

Should you brine salmon before smoking?

Brining salmon for 8-12 hours before smoking helps season the fish, retains moisture, and improves texture. A basic brine of 1 cup kosher salt per gallon of water works great. Rinse and pat the salmon dry after brining before smoking.

How do you keep smoked salmon moist?

Brining before smoking helps salmon retain moisture. Using a lower temperature (225°F) prevents overcooking and drying. Avoid opening the smoker frequently, and let the smoked salmon rest for 30 minutes before slicing to redistribute juices.

Tips for Serving Smoked Salmon

Smoked salmon is delicious eaten on its own, but it also pairs wonderfully with other ingredients. Here are some serving ideas to take your smoked salmon to the next level:

  • Serve on top of a fresh bagel with cream cheese, tomato, red onion, capers, and fresh dill. A classic smoked salmon bagel!
  • Dice or flake smoked salmon over a salad with mixed greens, shaved fennel, grated parmesan, and a lemony vinaigrette.
  • Fold smoked salmon into a mushroom risotto along with peas and lemon zest. The richness pairs perfectly.
  • Top bruschetta with flaked smoked salmon, whipped cream cheese, diced red onion, and chopped chives.
  • Layer smoked salmon with sliced cucumbers, goat cheese, arugula, and whole grain crackers for an appetizer.
  • Mix flaked salmon into scrambled eggs with fresh chives and a pinch of garlic powder. Amazing for breakfast!

However you choose to serve it up, smoked salmon always adds a pop of flavor. It’s my go-to way to dress up any meal.


For me, smoking salmon over a low 225°F heat is one of the best ways to coax out incredibly flavorful, silky fish. With the proper brining time, smoking temperature, and internal temperature, you can achieve restaurant-quality smoked salmon at home. Use the guidelines in this article to master the art of smoking salmon low and slow. I hope you’ll soon enjoy the nostalgic smoky goodness of salmon smoked over real wood. Delicious!
