It can be hard to come up with new meals during the week. Work can run late, meaning that you don’t get many evenings when you can make a simply delicious meal and enjoy it.

I have a solution for you: baked salmon. I love a dinner like this. I can pop it in the oven and get a few more things done while it’s cooking. This way, the food and I are ready to sit down and enjoy our time spent together.

Recipe ingredients

It has a fish fillet and three simple ingredients that you probably already have on hand in your pantry. Here’s the list:

• Salmon – Main protein; choose similar-sized pieces for even cooking
• Brown sugar – Creates a sweet caramelized exterior and balances soy sauce
• Soy sauce – Provides savory depth and helps season the fish
• Olive oil – Keeps salmon moist and helps with caramelization

Optional Finishing Touches:

• Fresh lemon juice – Adds brightness
• Fleur de sel – Enhances flavors
• Fresh herbs – For garnish

Choosing Your Salmon

Fresh vs. Frozen:

• Fresh: Best when available
• Frozen: Convenient and works great (Costco portions recommended)
• Look for: Bright color, firm texture, no strong fishy smell

Costco salmon is perfect for this recipe

I love to shop at Costco. This is a great baked salmon recipe for Costco salmon because they sell frozen salmon in individual packages, which are perfect for dinner.

I also buy fresh salmon at the store, but I love having a few tasty meals in the freezer. If I am using the frozen fish from Costco, I will take the pieces out of the freezer and put them in the refrigerator when I leave for work in the morning. This way, they will be defrosted and ready to be cooked when I get home.

Pro Tips for Perfect Salmon

• Look for opaque flesh that flakes easily

Common Questions & Troubleshooting

Q: How do I know when salmon is done?
A: Three ways to check:

• Internal temperature of 140°F
• The flesh is opaque throughout
• Fish flakes easily with a fork

Q: Can I use frozen salmon?
A: Yes! Thaw in the refrigerator overnight or during the workday. Pat dry before cooking.

What to serve with baked salmon

Here are some great side dishes to serve along with salmon:

Cooking during the week doesn’t have to be boring. You don’t have to cook only chicken because there are other tasty alternatives. I hope you enjoy one of my favorite baked salmon recipes.

How to make perfect baked salmon every time

1. Allow your salmon to warm up to room temperature. Take it out of your refrigerator and let it rest on your kitchen counter for 15-30 minutes. This will help promote even cooking.
2. Don’t rinse your salmon – water can break down the flesh. Instead, gently pat the salmon all over with a paper towel.
3. Leave the skin on and bake the salmon with the skin side down. The skin will help protect the salmon from the heat of the pan and prevent it from drying out while cooking. When you take the salmon out of the pan, the skin will come off easily if you slide a spatula between the skin and the fillet.
4. Bake salmon at 350°F. The internal temperature of the salmon should reach 140°F. This translates to about 4-6 minutes for every 1/2-inch of thickness. If you don’t use a thermometer, you can test for doneness by inserting a knife or fork into a thick part of the salmon and twisting it a bit; the fish should be opaque (i.e., not transparent) and flake easily.
5. Don’t overcook your salmon. Ideally, remove the salmon from the oven before it’s “done” as it will continue cooking while it rests.

Storage & Reheating Instructions

• Refrigerator Storage: Store cooked salmon in airtight containers for up to 2 days in refrigerator for optimal quality and food safety.
• Freezing Not Recommended: Cooked salmon doesn’t freeze well and loses texture upon thawing.
• Reheating Methods: Gently reheat in 275°F oven for 15 minutes or microwave in 30-second intervals until warmed through.
• Cold Serving Option: Leftover salmon is served well in salads or on bagels with cream cheese.
• Best Fresh: Salmon is best enjoyed immediately after cooking for optimal texture and flavor.
