If you’re wondering how long to bake salmon at 350 in the oven, you’ve come to the right place. This temperature is a popular choice for its balance of gentle cooking and efficiency, and getting the timing right is the key to perfect fish.
Baking salmon at 350°F is a straightforward method that yields tender, flaky results. The exact time can vary, but a general rule is 12 to 15 minutes for a typical fillet. This guide will walk you through everything you need to know, from preparation to plating, ensuring your salmon turns out great every single time.
How Long To Bake Salmon At 350 In The Oven
The core answer is 12 to 15 minutes for a standard 6-ounce fillet that’s about 1 inch thick. However, several factors influence this time. The most reliable method is to use an instant-read thermometer. You should remove the salmon from the oven when its internal temperature reaches 125°F to 130°F in the thickest part. It will continue to cook from residual heat (called carryover cooking) to reach the FDA-recommended safe temperature of 145°F.
Here’s a quick reference guide based on thickness:
- 1/2 inch thick: 8 to 10 minutes
- 1 inch thick: 12 to 15 minutes
- 1 1/2 inches thick: 15 to 18 minutes
- Whole side of salmon (1.5-2 lbs): 20 to 25 minutes
Remember, these are estimates. Always check for doneness visually and with a thermometer for the best results.
Why 350 Degrees Fahrenheit is an Ideal Temperature
Baking at 350°F offers a gentle, even heat that cooks the salmon through without drying out the exterior. It’s hot enough to cook the fish efficiently but not so hot that it sears or overcooks the outside before the inside is done. This temperature is very forgiving, making it perfect for both beginners and experienced cooks.
It also allows time for flavors from marinades or seasonings to meld with the fish. Higher temperatures can sometimes cause sugary glazes to burn before the fish is cooked, while lower temperatures might not cook it evenly.
Essential Tools for Baking Salmon
You don’t need fancy equipment. A few basics will set you up for success.
- Rimmed Baking Sheet: Prevents juices from spilling into your oven.
- Parchment Paper or Aluminum Foil: Makes cleanup incredibly easy and helps prevent sticking.
- Instant-Read Thermometer: The single best tool for guaranteeing perfectly cooked salmon.
- Fish Spatula: Its thin, flexible edge slides easily under the delicate fillet without breaking it.
- Small Bowl and Brush: For mixing and applying oils, marinades, or glazes.
Choosing Your Baking Surface: Parchment vs. Foil
Both have their advantages. Parchment paper provides a naturally non-stick surface and promotes slight browning on the bottom of the fish. Aluminum foil creates a tighter seal, which can be useful if you want to trap steam for a more moist result, or if you’re making a messy glaze. You can even lightly oil the baking sheet directly if you don’t have either.
Step-by-Step Guide to Baking Salmon at 350°F
Follow these simple steps for flawless salmon.
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F. This ensures consistent cooking from the moment the fish goes in. While the oven heats, line your baking sheet with parchment paper or foil for easy cleanup.
Step 2: Prepare the Salmon Fillets
Pat the salmon fillets completely dry with paper towels. This is crucial because moisture on the surface will steam the fish instead of letting it bake nicely. Check for and remove any tiny pin bones with a pair of clean tweezers. Then, place the fillets skin-side down (if the skin is on) on the prepared baking sheet. Drizzle or brush lightly with olive oil, and season generously with salt and pepper.
Step 3: Seasoning and Flavoring Ideas
Salt and pepper are just the beginning. Here are some simple flavor profiles:
- Lemon & Dill: Top with thin lemon slices and fresh dill sprigs.
- Maple Soy Glaze: Mix 2 tbsp soy sauce, 1 tbsp maple syrup, and 1 minced garlic clove. Brush on before and halfway through baking.
- Herb Crust: Combine breadcrumbs, chopped parsley, dill, and a little melted butter. Press onto the top of the fillets.
- Simple Spice Rub: Use a mix of paprika, garlic powder, onion powder, and a touch of brown sugar.
Step 4: Baking Time and Doneness Check
Place the baking sheet in the preheated oven. Set your timer for the minimum suggested time based on thickness (e.g., 12 minutes for a 1-inch fillet). When the timer goes off, check for doneness. The salmon should look opaque and should flake easily when gently prodded with a fork. The most accurate method is to insert an instant-read thermometer into the thickest part of the fillet. Aim for 125-130°F for medium doneness.
If it’s not done, return it to the oven and check every 2 minutes. Remember, it continues too cook after you take it out, so err on the side of slightly underdone.
Step 5: Resting and Serving
Once out of the oven, let the salmon rest on the baking sheet for 3-5 minutes. This allows the juices, which have been driven to the center by the heat, to redistribute throughout the fillet. This step ensures every bite is moist. Serve it directly from the baking sheet or carefully transfer to plates with your fish spatula.
Common Mistakes to Avoid
Avoiding these pitfalls will improve your results instantly.
- Not Preheating the Oven: A cold start leads to uneven cooking.
- Skipping the Dry Step: Wet fish steams and can become rubbery.
- Overcrowding the Pan: Leave space between fillets for hot air to circulate.
- Overcooking: This is the most common error. Trust the thermometer, not just the clock.
- Skipping the Rest: Cutting in immediately lets all the flavorful juices escape onto the plate.
How to Tell When Your Salmon is Perfectly Cooked
Use a combination of these signs to be sure:
- Temperature: 125-130°F in the thickest part for medium (it will rise to 145°F).
- Texture: The flesh flakes apart easily with a fork. It should not look translucent or raw in the center.
- Color: The salmon turns from a vibrant, deep pink or orange to a lighter, opaque pink throughout.
- Feel: When pressed gently with a finger, it should feel firm but still have a little give, not hard.
Recipe Variations for Baked Salmon
Once you master the basic technique, you can try these easy variations.
Baked Salmon with a Honey Garlic Glaze
In a small saucepan, warm 3 tbsp honey, 3 minced garlic cloves, 2 tbsp soy sauce, and 1 tbsp lemon juice until simmering. Brush half the glaze on the salmon before baking, and the other half in the last 5 minutes of cooking for a sticky, flavorful finish.
One-Pan Salmon and Vegetables
Cut vegetables like asparagus, broccoli, or bell peppers into similar-sized pieces. Toss them with oil, salt, and pepper. Spread them on the same baking sheet, roast for 10 minutes at 350°F, then push them to the side and add the seasoned salmon fillets to the center. Bake for another 12-15 minutes until the salmon is done. It’s a complete meal on one pan.
Baked Salmon with a Parmesan Herb Crust
Mix 1/4 cup grated Parmesan, 2 tbsp breadcrumbs, 1 tbsp chopped parsley, 1 tsp lemon zest, and 1 tbsp olive oil. Pat this mixture onto the top of each oiled salmon fillet before baking. It creates a deliciously crispy, savory topping.
Storing and Reheating Leftover Baked Salmon
Leftover salmon is wonderful in salads, pastas, or on its own.
- Storage: Let it cool, then place in an airtight container in the refrigerator for up to 2 days.
- Reheating (Best Methods):
- Oven: Place on a foil-lined sheet, add a splash of water, cover with foil, and warm at 275°F for about 15 minutes.
- Skillet: Gently reheat in a non-stick skillet over low heat with a lid on, adding a teaspoon of water to create steam.
Avoid the microwave if you can, as it tends to dry out and overcook the fish very quickly, making it rubbery.
Frequently Asked Questions (FAQ)
How long does it take to bake salmon at 350?
For a standard 1-inch thick fillet, it takes 12 to 15 minutes at 350°F. Always check for doneness with a thermometer.
Should you bake salmon covered or uncovered?
Typically, bake it uncovered. Covering it with foil will steam the fish, resulting in a softer texture. Uncovered baking allows for slight browning and a firmer, flakier texture.
Do you flip salmon when baking?
No, you do not need to flip salmon when baking. Place it skin-side down (if it has skin) and leave it that way. This protects the delicate flesh from direct heat and allows the skin to crisp up if you’re cooking it that way.
What is the best temperature to cook salmon in the oven?
350°F is an excellent all-purpose temperature. Some recipes use higher temps (400-425°F) for a shorter time for a crisper edge, but 350°F is reliable and forgiving for moist, evenly cooked salmon.
Can I bake frozen salmon at 350?
Yes, but you’ll need to add time. Bake frozen salmon fillets (without thawing) at 350°F for 20 to 25 minutes, or until they reach the proper internal temperature. Check them a few minutes early just in case.
