What Is Baked Salmon With Garlic Mayo?
This dish is a roasted salmon fillet topped with a garlicky mayonnaise mixture and baked until the exterior is lightly browned and the interior flakes easily with a fork. It tastes rich and savory from the mayo and garlic, with a herbal lift from fresh dill and a hint of salt and pepper to finish. Baking is the primary cooking method—gentle, even heat that cooks the fish through without drying it. People often serve it for dinner, but it’s equally welcome on a leisurely weekend lunch or as the centerpiece for a small dinner gathering. The overall vibe is comforting yet elegant: generous garlic flavor, soft flaky fish, and a fresh herb note that keeps it bright.
Ingredients for Baked Salmon With Garlic Mayo
For the Salmon
- 2 lbs fresh salmon fillet (skin on)
For the Garlic Mayo
- 1/2 cup mayonnaise (slightly heaping)
- 8 cloves garlic (crushed)
- 5 oz fresh dill (chopped)
- 1/2 tsp salt
- 1/4 tsp black pepper
Ingredient Notes (Substitutions, Healthy Swaps)
- Mayonnaise: For a lighter option, use a light or reduced-fat mayonnaise—texture will be slightly less rich but still protective during baking. You may also try an olive-oil-based mayonnaise for a different fat profile.
- Garlic: If fresh garlic is too intense, use 1–2 teaspoons of jarred crushed garlic as a milder alternative (still use only what’s listed if you want the original profile).
- Dill: If you don’t have fresh dill, a small amount of dried dill (about 1–1.5 teaspoons) can work in a pinch, but fresh gives a brighter flavor.
- Salt & Pepper: Adjust to taste—start with the listed amounts and add more after baking if needed.
- Salmon: This recipe works with any skin-on salmon fillet—Atlantic, coho, or sockeye. If you have portioned fillets, reduce bake time slightly.
Step-by-Step Instructions
Step 1 – Prep the Oven and Salmon
Place a rack in the center of your oven and preheat to 400°F (200°C). Line a baking sheet with foil or parchment for easy cleanup and set the salmon skin-side down on the sheet. Pat the salmon dry with paper towels so the mayo adheres well.
Visual cue: The fillet should look dry to the touch and evenly laid out on the sheet.Step 2 – Make the Garlic Mayo
In a small bowl, combine the mayonnaise, crushed garlic, chopped dill, salt, and black pepper. Stir until evenly mixed and the garlic is distributed throughout the mayo.
Pro cue: Let the mixture sit for 5–10 minutes if you have time—this mellows raw garlic slightly and infuses the mayo with dill.Step 3 – Spread the Sauce
Use a spoon or offset spatula to spread the garlic-mayo mixture evenly over the top of the salmon, leaving the skin side untouched.
Visual cue: The fillet should have a uniform, about 1/8–1/4-inch coating of the garlic mayo on top.Step 4 – Bake
Place the baking sheet in the preheated oven and bake for 12–18 minutes, depending on the thickness of your fillet. The salmon is done when it flakes easily with a fork and the top is lightly golden.
Pro cue: For a slightly crispier finish on the top, switch the oven to broil for 1–2 minutes at the end—watch closely to avoid burning.Step 5 – Rest and Serve
Remove the salmon from the oven and let it rest for 3–5 minutes before slicing. Resting lets the juices redistribute so the fish stays moist when served.
Visual cue: The flesh will be opaque and flake into large, moist flakes rather than dry crumbs.
Pro Tips for Success
- Pat the salmon dry before applying the mayo so it sticks properly and the skin can crisp.
- Use evenly sized fillets so they bake in the same time; thicker sections need a few extra minutes.
- Don’t overbake: check for doneness at the lower end of the time range and test by flaking the thickest part with a fork.
- Fresh dill gives the best flavor; add it at the last minute—heat dulls herb freshness.
- If your mayo is very cold, let it sit at room temperature for a few minutes to spread easily.
- For an extra-savory top, press some of the garlic into the mayo so the garlic flavor is distributed, but avoid large raw garlic chunks if you prefer a milder bite.
- Taste the mayo mix before spreading (use a tiny dab) and adjust salt if needed.
Flavor Variations (OPTIONAL)
- Spicy version: Add a pinch of cayenne or a small amount of crushed red pepper to the mayo for heat.
- Herby twist: Swap half the dill for chopped parsley or chives for a different herbal note.
- Lighter version: Use reduced-fat mayonnaise and double the dill for brightness to compensate for the lighter mouthfeel.
- Citrus lift (OPTIONAL): Add a small amount of lemon zest to the mayo if you have it on hand—this is optional and not part of the base recipe.
- Mild mustard boost: Mix in a teaspoon of Dijon-style mustard for tang (optional).
Serving Suggestions
- Serve with roasted baby potatoes or a simple mash to soak up the creamy mayo flavors.
- Pair with a crisp green salad or butter lettuce and thinly sliced cucumber for contrast and freshness.
- Plate beside steamed green beans or blanched asparagus for a light, springtime meal.
- Offer crusty bread to mop up any garlicky juices.
- For casual dinners, flake leftovers into salads or sandwiches.
- If you have leftovers, transform them into tacos or a lively lunch—try making BBQ salmon tacos with mango slaw using the extra salmon for a bright change of pace.
Make-Ahead, Storage & Reheating
- Make-ahead: You can mix the garlic mayo up to a day ahead and store it covered in the refrigerator. Keep the salmon chilled separately and assemble just before baking.
- Refrigerator storage: Store cooked salmon in an airtight container for up to 3 days.
- Reheating: Reheat gently in a 300°F (150°C) oven for 8–10 minutes or until warmed through. Reheating in the microwave will warm it faster but can make the texture slightly softer—use short bursts and check frequently.
- Texture changes: Mayo-topped salmon will be best the day it’s baked; refrigeration can firm the mayo slightly and the top won’t be as crisp after reheating.
Storage and Freezing Instructions
- Freezing cooked salmon: You can freeze cooked salmon, but the texture will change slightly after thawing (it may become a touch drier). Wrap tightly in plastic wrap and place in a freezer bag for up to 2 months.
- Freezing uncooked: It’s better to freeze raw salmon before adding the mayo. If you do freeze raw fillet, thaw overnight in the refrigerator before applying the mayo and baking.
- Thawing: Thaw frozen cooked or raw salmon in the refrigerator overnight for best results.
- If you prefer not to freeze, repurpose leftovers within 3 days into salads, bowls, or tacos for the best texture.

FAQ About Baked Salmon With Garlic Mayo
Q: How do I know when the salmon is done?
A: The flesh should be opaque and flake easily with a fork at the thickest part. Aim for 12–18 minutes at 400°F depending on thickness.
Q: Can I use frozen salmon?
A: Thaw frozen salmon in the refrigerator overnight before applying the mayo and baking for even cooking.
Q: My garlic tastes very strong—how can I mellow it?
A: Let the crushed garlic sit in the mayo for 5–10 minutes before spreading; resting mellows raw garlic. You can also reduce the garlic slightly.
Q: How do I keep the salmon from drying out when reheating?
A: Reheat gently in a low oven (300°F) covered for short periods or add a splash of water under the foil to create steam and preserve moisture.
Q: Can I make the garlic mayo ahead of time?
A: Yes—make the mayo up to 24 hours ahead. Store tightly covered in the refrigerator and give it a quick stir before using.
Q: Is it safe to eat slightly pink salmon?
A: Yes—salmon can be safely eaten when the internal temperature reaches 145°F, but many prefer it slightly less cooked and opaque with some pink. Use a thermometer if you need precision.
Notes
- Plate on a warmed dish to keep the salmon warm longer when serving guests.
- A final sprinkle of fresh chopped dill right before serving brightens flavors and adds color.
- If salt levels seem low, always season lightly after cooking and let each diner add more if needed.
- Slice against the grain into portions for clean presentation and easy serving.
- For a crispier skin, pat the skin dry and place the fillet skin-side down on a hot baking surface before topping.
- Leftovers reheat well when flaked into a warm grain bowl or salad for a quick lunch.
