Baking salmon is one of the easiest ways to prepare a healthy, flavorful meal. Cooking it at 350°F is a popular method because it gently cooks the fish, keeping it moist and tender. However, knowing the right baking time is essential to avoid overcooked or undercooked salmon.
How Long to Bake Salmon at 350°F
The baking time for salmon depends on the thickness of the fillet or steak. As a general rule:
- For a 1-inch thick fillet: Bake for 20-25 minutes.
- For a 1.5-inch thick fillet: Bake for 25-30 minutes.
- For salmon steaks: Bake for 30 minutes, depending on thickness.
Salmon is done when it flakes easily with a fork and the internal temperature reaches 145°F (63°C). Using a meat thermometer is the most accurate way to check doneness.
Steps to Bake Salmon at 350°F
- Preheat the Oven: Set your oven to 350°F (175°C).
- Prepare the Salmon: Pat the salmon dry and season with salt, pepper, lemon, herbs, or your favorite marinade.
- Use a Baking Dish: Lightly grease a baking dish or line it with parchment paper.
- Bake: Place the salmon skin-side down (if it has skin) and bake for the recommended time based on thickness.
- Check Doneness: Test with a fork or thermometer. Remove from oven immediately when done to prevent overcooking.
Tips for Perfect Baked Salmon
- Don’t Overcrowd the Pan: Make sure there’s space around the fillets for even cooking.
- Add Moisture: Brush salmon with olive oil or melted butter to prevent it from drying out.
- Cover with Foil: Tent a piece of foil over the fish for the first half of baking to retain moisture.
- Flavor Boost: Add lemon slices, garlic, or fresh herbs on top before baking for extra flavor.
Benefits of Baking Salmon at 350°F
- Gentle Cooking: Slower baking at 350°F prevents the fish from drying out.
- Even Cooking: The heat penetrates slowly, ensuring the salmon cooks evenly.
- Retains Nutrients: Lower temperatures help preserve omega-3 fatty acids and vitamins.
Alternative Cooking Times
If you prefer your salmon slightly firmer or softer:
- For very tender salmon: Bake at 325°F for 25-30 minutes.
- For slightly crisp edges: Bake at 375°F for 15-20 minutes.
Adjust the time based on your oven and the thickness of the fillet.
FAQs About Baking Salmon at 350°F
1. Can I bake frozen salmon at 350°F?
Yes, but it will take longer—typically 30-35 minutes for a 1-inch thick fillet. It’s best to thaw salmon first for even cooking.
2. Should I cover the salmon with foil?
Covering is optional. Foil helps keep the fish moist, especially for thicker fillets. Remove it during the last 5-10 minutes for a slightly crisp top.
3. How do I know when salmon is done?
The salmon should flake easily with a fork, and the internal temperature should reach 145°F (63°C). Avoid overcooking, which makes it dry.
4. Can I bake salmon with skin on?
Yes. Baking with skin on protects the flesh and makes it easier to remove after cooking.
5. What sides go well with baked salmon?
Salmon pairs well with roasted vegetables, rice, quinoa, or a fresh salad. Lemon wedges and dill add extra flavor.
6. Can I bake salmon in foil packets at 350°F?
Absolutely. Baking in foil packets (en papillote) keeps the salmon moist and allows you to add vegetables, herbs, or sauces for a complete meal.
Baking salmon at 350°F is simple, healthy, and versatile. By following the right timing based on thickness, checking the internal temperature, and using a few tips for moisture and flavor, you can achieve perfectly cooked salmon every time. Whether you’re cooking a quick weeknight dinner or preparing a special meal, this method is both reliable and delicious.
