Baked Salmon with Spinach is a simple, healthy meal that brings together tender, flaky salmon and vibrant, fresh spinach. The salmon bakes perfectly in the oven, staying juicy and full of flavor, while the spinach adds a nice, light green touch and a little bit of earthiness to the dish.
I love how easy this recipe is to put together, and it feels like a special dinner even on a busy weeknight. I usually season the salmon with some lemon, garlic, and a pinch of salt, then lay it on a bed of sautéed spinach before baking. It’s one of those meals that feels fancy but doesn’t take a lot of time or effort. Plus, it’s packed with nutrients, so I like knowing I’m eating something good for me.
My favorite way to serve this baked salmon with spinach is alongside some warm rice or boiled potatoes. Sometimes I add a squeeze of fresh lemon over the top just before eating to brighten all the flavors. It’s simple, tasty, and gets everyone asking for seconds. This dish has become a go-to when I want something healthy but still comforting and satisfying.
Key Ingredients & Substitutions
Salmon: Fresh salmon fillets shine in this dish. I like skinless ones for easy plating. If salmon isn’t available, try trout or cod for a similar texture. Frozen fillets work well too—just thaw first.
Spinach: Fresh spinach cooks quickly and tastes light. Baby spinach is great because it wilts fast and stays tender. You can substitute with kale or Swiss chard if you prefer a heartier green, but cook a bit longer.
Herbs & Lemon: Fresh chives, thyme, lemon juice, and zest add brightness and freshness. If you don’t have these, dried thyme works, and lemon juice can be swapped with a splash of vinegar or lime juice for tang.
Butter & Olive Oil: Combining butter and olive oil helps cook the spinach and adds richness. You can use all olive oil or even a little coconut oil if needed, but butter adds that lovely creamy flavor.
How Do You Make the Salmon Tender and Flavorful Without Overcooking?
Baking salmon just right is the key to its moist, flaky texture. Here’s what I do:
- Pat dry salmon before seasoning to help it brown nicely.
- Sear skinless salmon in a hot skillet with olive oil for 2-3 minutes to create a crisp edge and lock juices.
- Top salmon with the herb and lemon mix before baking to infuse flavor.
- Oven bake at 400°F (200°C) for 7-10 minutes—check at 7 mins; salmon flakes easily when done but isn’t dry.
- Rest salmon briefly after baking; it keeps cooking a little from residual heat.
Following this tips, you get salmon that’s juicy and full of flavor every time.
Equipment You’ll Need
- Oven-safe skillet – perfect for searing the salmon and finishing it in the oven without extra dishes.
- Small mixing bowl – great for combining the garlic, herbs, and lemon juice easily.
- Tongs or spatula – helps flip salmon gently without breaking it.
- Large sauté pan – ideal for cooking the spinach quickly and evenly.
- Sharp knife and cutting board – necessary for chopping herbs and preparing lemon zest.
Flavor Variations & Add-Ins
- Swap salmon for trout or cod – these fish hold up well when baked and offer a milder flavor.
- Add toasted pine nuts or slivered almonds to the spinach – for extra crunch and a nutty note.
- Mix in a handful of sun-dried tomatoes with the spinach – adds sweet and tangy bursts.
- Season salmon with smoked paprika or cayenne pepper – for a gentle smoky or spicy kick.

Step-by-Step Instructions:
1. Prepare the Oven and Salmon:
Preheat your oven to 400°F (200°C). Pat your salmon fillets dry with paper towels, then season both sides with salt and pepper to taste.
2. Make the Herb and Lemon Mixture:
In a small bowl, mix the minced garlic, fresh lemon juice, lemon zest, chopped chives, and thyme leaves. This will add fresh, zesty flavor to the salmon.
3. Sear the Salmon:
Heat half the olive oil (about ½ tablespoon) in an oven-safe skillet over medium-high heat. Place the salmon fillets in the pan and sear for 2–3 minutes, until the bottom is beautifully browned.
4. Add Herbs and Bake:
Flip each salmon fillet gently. Spoon the garlic-herb mixture on top, then transfer the skillet to the preheated oven. Bake for 7–10 minutes, until the salmon is cooked through and flakes easily with a fork.
5. Cook the Spinach:
While the salmon bakes, heat the remaining ½ tablespoon olive oil and 2 tablespoons butter in a separate large skillet on medium heat. Add the fresh spinach and cook, stirring occasionally, until wilted, about 3–4 minutes. Season with salt and pepper to taste.
6. Serve Your Dish:
On each plate, spread a bed of the sautéed spinach. Place a salmon fillet on top. Spoon any pan juices and herbs from the baking skillet over the salmon. Garnish with extra chopped chives and add lemon wedges on the side for an optional fresh squeeze.
