Step-by-Step Instructions
1. Prepare the Oven
Preheat the oven to 400°F (200°C).
Lightly grease a medium baking dish or roasting pan.
Pat the salmon fillets completely dry with paper towels, especially the skin.
2. Season the Salmon
Brush the salmon lightly with olive oil.
Season evenly with salt, black pepper, garlic powder, and smoked paprika.
Allow the salmon to sit for about 10 minutes while preparing the sauce.
3. Make the Lemon Garlic Butter Sauce
In a small bowl, whisk together melted butter, minced garlic, lemon juice, broth, honey, Dijon mustard, lemon zest, thyme, Italian seasoning, and red pepper flakes if using.
Mix until well combined.
4. Assemble the Baking Dish
Pour approximately half of the lemon garlic butter sauce into the bottom of the baking dish.
Arrange the salmon fillets in a single layer with the skin facing upward if you want the skin exposed and browned.
Scatter the cherry tomatoes around the salmon.
Place lemon wedges or slices between the fillets and add several fresh thyme sprigs.
5. Add the Remaining Sauce
Spoon some of the remaining garlic butter sauce around the salmon.
Avoid completely covering the skin so it has a better chance of becoming golden during baking.
Reserve a small amount of sauce for serving if desired.
6. Bake the Salmon
Transfer the baking dish to the oven.
Bake for approximately 12–16 minutes, depending on the thickness of the fillets.
The salmon should become opaque and flake easily when gently pressed with a fork.
For food safety, the thickest portion can be cooked to 145°F (63°C).
7. Roast the Tomatoes
During baking, the cherry tomatoes will soften and blister, releasing their sweet juices into the lemon butter sauce.
If the tomatoes are particularly large, they may need a few additional minutes.
8. Brown the Salmon
For the deeper golden finish shown in the dish, switch the oven to broil.
Broil for approximately 1–2 minutes, watching carefully.
Remove the pan as soon as the salmon develops attractive caramelized spots.
9. Finish and Serve
Allow the salmon to rest for about 2–3 minutes.
Spoon the warm lemon garlic butter sauce and roasted tomato juices around each fillet.
Finish with fresh parsley, thyme, cracked black pepper, and additional fresh lemon.
Serve immediately.
Cooking Tips
- Pat the salmon thoroughly dry before seasoning for better browning.
- Choose fillets of similar thickness so they cook evenly.
- Fresh lemon juice produces the brightest flavor.
- Keep most of the sauce underneath or around the fish if you want the skin to stay crisp.
- Avoid overcooking salmon because it can dry out quickly.
- Broil only briefly at the end because butter and honey can caramelize fast.
- Fresh thyme pairs especially well with lemon, garlic, and salmon.
Serving Suggestions
Serve this baked lemon garlic butter salmon with:
- Garlic roasted potatoes
- Creamy mashed potatoes
- Steamed jasmine rice
- Roasted asparagus
- Green beans

Storage
Store leftover salmon, tomatoes, and sauce in an airtight container in the refrigerator for up to 2 days.
Reheat gently in a 300°F (150°C) oven until just warmed through.
Avoid overheating, as salmon becomes dry quickly.

- Flake leftover salmon over a fresh salad.
- Serve it over rice with the roasted tomatoes and extra sauce.
- Toss pieces of salmon with lemon butter pasta.
- Add chilled salmon to wraps with avocado and greens.
- Serve over quinoa with roasted vegetables.
FAQs
Can I use frozen salmon?
Yes. Thaw it completely in the refrigerator and pat it thoroughly dry before cooking.
Can I use skinless salmon?
Absolutely. Skinless fillets work just as well, although the presentation and texture will be slightly different.
Can I add vegetables to the baking dish?
Yes. Asparagus, zucchini, bell peppers, or thin green beans all pair beautifully with this recipe.
Can I make the sauce creamy?
Yes. Stir about ½ cup heavy cream into the pan juices after the salmon has finished baking for a creamy lemon garlic variation.
Can I use another fish?
Yes. Cod, halibut, sea bass, or trout can be prepared with the same lemon garlic butter sauce, with cooking time adjusted according to thickness.
