For the Roasted Salmon & Fennel
- 4 salmon fillets about 5 oz each
- 1 fennel bulb trimmed and sliced into wedges
- 3 tablespoons extra virgin olive oil divided (some for the fennel, some for brushing the salmon)
- 1 teaspoon salt divided (adjust to taste)
- ½ teaspoon freshly ground black pepper divided (adjust to taste)
For the Chimichurri
- ½ cup fresh parsley firmly packed
- ¼ cup fresh cilantro firmly packed — use more if needed to get enough herb volume
- 2 tablespoons red wine vinegar or to taste
- 2 cloves garlic roughly chopped
- ¼ teaspoon chili flakes or more if you like spice
- ½ teaspoon dried oregano or 1 teaspoon fresh, if available
- ¼ teaspoon salt adjust to taste
- ¼ teaspoon freshly ground black pepper adjust to taste
- ¼ cup extra virgin olive oil for the sauce
For the Spinach
- 8 cups fresh spinach about 2 cups per serving, loosely packed
- 1 tablespoon extra virgin olive oil
- Pinch of salt and pepper
Optional
- 1 avocado sliced into four portions (about ¼ avocado per person)
Roast the Fennel
Slice your fennel bulb into wedges (about ½-inch thickness).
Arrange fennel slices on a baking sheet.
Drizzle with 1–2 tablespoons of the olive oil and sprinkle with half of the salt and pepper.
Roast for 20–25 minutes, or until fennel is lightly caramelized. (You’ll add the salmon to the oven shortly so they can finish together.)
Prepare the Chimichurri
While the fennel is roasting, make the sauce.
In a small food processor or blender, combine:
Parsley
Cilantro
Red wine vinegar
Garlic
Chili flakes
Dried oregano
Salt and pepper
Pulse until finely chopped.
Slowly drizzle in ¼ cup olive oil while pulsing, until you get a rough sauce. Adjust vinegar, salt, and pepper to taste.
Reserve half of the chimichurri for serving and use the other half to brush onto the salmon before roasting (optional).
Season & Roast the Salmon
Lightly brush each salmon fillet with the remaining 1 tablespoon of olive oil (or use some of the chimichurri instead).
Sprinkle with the remaining salt and pepper.
After the fennel has roasted for about 10 minutes, push the fennel to one side of the baking sheet and place the salmon fillets on the other side.
Return to the oven and roast for 10–12 minutes, depending on the thickness of the salmon, until the internal temperature reaches 145°F (63°C) or until it flakes easily with a fork.
Sauté the Spinach
While the salmon is finishing in the oven, warm 1 tablespoon olive oil in a skillet over medium heat.
Add the spinach, season with a small pinch of salt and pepper, and sauté just until wilted (1–2 minutes).
Assemble & Serve
Place a mound of sautéed spinach on each plate.
Add a portion of roasted fennel.
Top each plate with a roasted salmon fillet.
Drizzle reserved chimichurri over the salmon.
For extra healthy fats, add ¼ avocado per plate.
