For the Salmon
- Coho Salmon (1 ½ pounds) – The main protein providing rich flavor and buttery texture; feel free to substitute with Sockeye or King salmon if you prefer.
For the Dressing
- Extra-Virgin Olive Oil (3 tablespoons) – Adds richness and aids in cooking, enhancing flavors; avocado oil can be a great substitute.

- Fennel Bulb (1) – Offers a subtle anise flavor, best used when thinly sliced; anise can serve as an alternative.
- Shallot (1) – Provides a mild onion flavor, enhancing sweetness; green onions can be used as a milder substitute.
- Lemon (½) – Brings freshness with zest and juice, balancing flavors beautifully; while there’s no perfect substitute, vinegar can work in a pinch.
- Honey (2 teaspoons) – Adds a touch of sweetness to balance the citrus flavors; agave syrup or maple syrup can serve as alternatives.
- Chopped Fresh Herbs (½ cup) – A mix of basil, tarragon, dill, or mint elevates flavor complexity; use any fresh herbs you love.

Step‑by‑Step Instructions for Slow Roasted Salmon with Fennel and Orange
Step 1: Preheat the Oven
Begin by preheating your oven to 200°F (93°C). While the oven warms up, grab a baking sheet and line it with parchment paper to ensure easy cleanup later. This low temperature will allow the salmon to cook gently, preserving its moisture and tenderness, resulting in a delicious Slow Roasted Salmon with Fennel and Orange.
Step 2: Prepare the Salmon
Once the oven is ready, place the coho salmon, skin-side down, onto the parchment-lined baking sheet. Using a brush, apply ½ tablespoon of extra-virgin olive oil over the fish, making sure to cover the surface evenly. This step adds richness and helps the salmon develop a beautiful glaze as it roasts.
Step 3: Juice and Slice the Orange
Next, take your orange and cut it in half. Juice one half and set the juice aside to use later, while thinly slicing the other half into half-moon shapes. These juicy orange slices will add brightness and flavor to your Slow Roasted Salmon, infusing it with a refreshing citrus aroma.
Step 4: Mix the Topping
In a medium bowl, combine the remaining olive oil, sliced fennel, orange pieces, reserved orange juice, shallot, lemon zest and juice, honey, chopped fresh herbs, kosher salt, and freshly cracked black pepper. Stir until well mixed, creating a fragrant topping full of flavor and textures that will complement the salmon beautifully.
Step 5: Assemble the Dish
Spread the orange-fennel mixture evenly over the salmon fillet, ensuring the topping covers the fish generously. As you do this, let the citrus and herbs intermingle, which will enhance the flavors during roasting. The vibrant colors of the toppings will make your Slow Roasted Salmon with Fennel and Orange visually stunning.
Step 6: Roast the Salmon
Place the baking sheet in the preheated oven and roast the salmon for 30-45 minutes. Check for doneness by using an instant-read thermometer; the ideal internal temperature should reach 125°F (52°C) in the center. The salmon will be opaque and flaky, ensuring it remains juicy and tender.
Step 7: Serve and Enjoy
Once the salmon is cooked to perfection, carefully remove it from the oven. Serve the Slow Roasted Salmon with Fennel and Orange directly from the baking sheet, allowing everyone to spoon extra pan juices over their portions. This rustic presentation keeps the meal warm and encourages sharing around the table.
Expert Tips for Slow Roasted Salmon
Choose the Right Salmon: Select coho, sockeye, or king salmon depending on your flavor preference. Each has a unique taste and fat content that will enhance the dish.
