Step‑by‑Step Instructions for Garlic-Rosemary Citrus Slow Roasted Salmon
Step 1: Preheat the Oven
Begin by preheating your oven to 300ºF (150ºC). This low and slow roasting method is crucial for creating perfectly tender and flaky Garlic-Rosemary Citrus Slow Roasted Salmon. Ensure your oven is fully heated to allow for even cooking, setting the stage for an aromatic experience in your kitchen.
Step 2: Prepare the Salmon
While the oven heats, take your 1.5 lb. center-cut salmon fillet and pat it dry with paper towels. Generously season both sides with sea salt and cracked black pepper. This simple seasoning enhances the fish’s natural flavors, ensuring each bite of the Garlic-Rosemary Citrus Slow Roasted Salmon is flavorful and satisfying.
Step 3: Arrange Citrus Slices
In a shallow baking dish, artfully arrange thin slices of the naval orange and lemon. These citrus layers not only create a beautiful base for the salmon but also infuse it with sweetness and acidity as it roasts. Ensure the slices are evenly spaced so that each piece has access to the heat and enhances the dish’s vibrant flavors.
Step 4: Add Garlic and Rosemary
Next, take 5 whole garlic cloves and smash them lightly using the flat side of a knife. Scatter the smashed garlic cloves around the citrus slices in the baking dish. Then, gently tuck in 3 sprigs of fresh rosemary amidst the citrus. The garlic and rosemary will impart a fragrant aroma to your Garlic-Rosemary Citrus Slow Roasted Salmon as it cooks.
Step 5: Assemble the Dish
Place the seasoned salmon fillet delicately over the citrus and garlic mixture in the baking dish. This positioning allows the fish to absorb the citrusy, garlicky goodness as it roasts. Drizzle 3/4 cup of extra-virgin olive oil over the salmon and the citrus, enhancing the flavors and ensuring the fish remains moist during the slow roasting process.
Step 6: Roast the Salmon
Slide the baking dish into the preheated oven and roast the Garlic-Rosemary Citrus Slow Roasted Salmon for 30 to 35 minutes. Keep an eye on it; the salmon is done when it becomes opaque and flakes easily with a fork, typically at medium-rare to medium doneness. This gentle cooking method enhances the dish’s overall tenderness and flavor.
Step 7: Serve the Salmon
Once the salmon is done, carefully remove the baking dish from the oven. Before serving, remove the citrus slices and garlic cloves if desired, as their primary role was to infuse flavor. Drizzle some of the infused olive oil from the dish over the salmon to amplify the deliciousness, and prepare to delight your family or guests with this stunning Garlic-Rosemary Citrus Slow Roasted Salmon.

Garlic-Rosemary Citrus Slow Roasted Salmon Recipe FAQs
How do I choose the best salmon?
Absolutely! When selecting salmon, look for bright, firm flesh and a clean, ocean-like smell. The skin should be shiny, and there shouldn’t be any dark spots or bruising. If purchasing from the fish counter, ask for center-cut fillets for an even cooking experience. If fresh isn’t available, I often opt for flash-frozen salmon that has been thawed properly; it can taste just as good!
How should I store leftovers of Garlic-Rosemary Citrus Slow Roasted Salmon?
Very straightforward! Store any leftover salmon in an airtight container in the refrigerator for up to 3 days. Ensure it cools completely before sealing. This will help maintain its flavor and moisture. For longer storage, wrap it tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. It can last up to 2 months in the freezer, though I recommend labeling it with the date!
Can I freeze Garlic-Rosemary Citrus Slow Roasted Salmon?
Absolutely! For freezing, prepare the salmon as usual, then once it has cooled completely, wrap it tightly in plastic wrap or aluminum foil. Ensure all air is pushed out, then place it in a freezer-safe bag. This helps avoid freezer burn, allowing the salmon to remain fresh for up to 2 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and gently reheat to preserve its delicate texture.
What if my salmon is overcooked?
No worries! If your salmon ends up overcooked and dry, you can try adding a splash of olive oil or tossing it with a squeeze of fresh lemon juice. This can help revive the flavor and moisture. For the next attempt, keep a close eye on the cooking time, checking the salmon’s doneness around the 30-minute mark. It’s best to aim for an internal temperature of about 125ºF for medium-rare.
Are there any dietary considerations I should be aware of?
Yes! This Garlic-Rosemary Citrus Slow Roasted Salmon recipe is gluten-free and packed with healthy fats and protein, making it suitable for many diets. However, if you’re cooking for someone with allergies, check for any sensitivities to garlic, seafood, or olive oil. If serving for pets, remember that salmon should only be given in moderation and ensure there are no bones remaining in the fish!
