📃 Ingredient description
Here are the main ingredients you’ll need for this easy salmon dinner:
- Salmon: Fresh salmon fillets are ideal; if using frozen, thaw completely in the refrigerator and pat dry before cooking.
- Olive oil: A good-quality olive oil works well; avocado oil or a small amount of butter are fine alternatives.
- Fennel bulbs: Mildly sweet with an anise-like scent, fennel adds freshness and texture. Use both the bulb and some fronds for garnish and flavor.
- Spinach: Fresh baby spinach wilts quickly and pairs beautifully with fennel and mustard; if using frozen spinach, squeeze out excess water first.
- Garlic: Fresh minced garlic brings savory depth; garlic powder can be used in a pinch.
- Whole grain mustard: Adds texture and a touch of sharpness to the sautéed greens.
💭 Variations and substitutions
These simple swaps keep the dish flexible:
- Swap spinach for baby kale or Swiss chard—cook a little longer if using heartier greens.
- Use lemon zest and a squeeze of lemon juice for a brighter finish.
- Replace wholegrain mustard with Dijon if you prefer a smoother sauce.
- For a richer finish, finish the salmon with a small pat of butter while resting.
How to pan-sear salmon
I pan-seared salmon with the skin on to get a crisp exterior, but you can remove the skin if you prefer.
- Bring salmon to room temperature for even cooking and pat dry with paper towels. Season with kosher salt and freshly ground black pepper.
- Heat a cast-iron skillet or heavy nonstick pan over medium-high heat and add olive oil. Place the salmon top side down (skin side up) and sear for about 4 minutes without moving it to develop color.
- Flip carefully with tongs and cook skin-side down for another 3 minutes, or until the internal temperature reaches about 125°F for medium-rare to medium. Adjust time for thicker fillets or a firmer doneness.
- Transfer salmon to a plate, loosely tent with foil, and let rest while you prepare the greens.
- Reduce heat to medium and add butter to the same pan. Sauté minced garlic briefly until fragrant, then add chopped fennel and reserved fronds along with wholegrain mustard. Cook for about 3 minutes to soften the fennel.
- Add the spinach and cook until just wilted, about 1–2 minutes. Season the greens with salt and pepper to taste.
- Serve the salmon on a bed of the sautéed fennel and spinach or spoon the greens alongside the fillets.
Simple sauce for salmon
A quick creamy sauce brightens the dish. Combine ¾ cup Greek yogurt with 1 tablespoon finely chopped fresh dill (or fennel fronds), ½ teaspoon honey, a little lemon zest if you like, a drizzle of extra-virgin olive oil, and a pinch of salt and black pepper. Stir to combine and spoon a dollop over the cooked salmon just before serving.
Side dishes to pair with salmon
Delicious options to serve with this salmon:
- Tri-color quinoa or a quinoa salad bowl
- Mixed vegetable salads
- Pasta with light sauces
- Creamy corn casserole or a vegetable quiche
- Butternut squash soup
- Mashed or roasted potatoes
- Grilled seasonal vegetables
How to store salmon with fennel
Store leftover salmon in an airtight container in the refrigerator for up to three days. Keep the cooked greens separate if possible, since they can release moisture and make the fish soggy. To reheat, warm the salmon gently in a skillet over medium heat until heated through. You can freeze cooked salmon for up to two months; thaw in the refrigerator before reheating.
📝 Recipe FAQs
Sear skin-side down for 3–4 minutes, then flip and cook the other side for about 3 minutes, adjusting for fillet thickness and desired doneness.
Season the salmon just before cooking. Salting too far in advance (more than about 15 minutes) can draw out moisture and dry the fish.
Salmon pairs well with citrus, dill, fennel, mustard, garlic, honey, and a variety of vegetables and grains. A light creamy or lemony sauce complements the fish beautifully.
