Baked Salmon Cajun Lime

My neighbor stopped by one evening with a bag of fresh salmon from the farmers market, and we decided to throw together something quick before sunset. I remembered having Cajun seasoning in my cabinet and a couple of limes on the counter, so we mixed them together on a whim. Twenty minutes later, we were sitting on the porch with plates full of the most vibrant, flavorful salmon either of us had made in ages. It became the recipe I return to whenever I want something that feels special but doesn't require much fussing.

I made this for my sister during one of those chaotic weeknight dinners when everyone's hungry and nobody wants to order takeout again. She took one bite and immediately asked for the recipe, which told me everything I needed to know about how well this actually works. The fact that it's also gluten-free and dairy-free meant everyone at the table could enjoy it without a second thought.

Ingredients

• Salmon fillets (4 pieces, about 170g each): Look for ones with skin still attached if you can, since it helps them stay moist and gives you a little texture contrast. Pat them completely dry before seasoning so the spices stick properly.
• Olive oil (2 tbsp): This is your binder and ensures the spice mixture adheres evenly; a good quality oil makes a noticeable difference in how golden everything gets.
• Cajun seasoning (2 tbsp): Store-bought works perfectly fine here, but check your label for heat level since brands vary. If you want to dial down the spice, use less and taste as you go.
• Salt and black pepper (1/2 tsp and 1/4 tsp): These balance the Cajun seasoning and shouldn't be skipped even though there's already salt in the blend.
• Limes (2 whole): One gets juiced over everything before baking, and the other gets sliced for a fresh finish that looks beautiful and adds tartness right before eating.
• Fresh cilantro or parsley (2 tbsp, chopped): This is optional but worth it, as it brightens the whole dish and adds a little herbaceous note that rounds out the heat.

Instructions

Get your oven ready and prep your pan:

Heat your oven to 200°C (400°F) while you line a baking tray with parchment paper. This takes just a minute but keeps your salmon from sticking and makes cleanup almost nonexistent.

Dry and arrange the salmon:

Pat each fillet dry with paper towels until they're really dry to the touch. Lay them skin-side down on your prepared tray, giving them a little space so they cook evenly.

Mix and coat the seasoning mixture:

Whisk together olive oil, Cajun seasoning, salt, and pepper in a small bowl until it looks like a paste. Brush or rub this generously over the top and sides of each fillet, making sure every surface gets flavored.

Squeeze fresh lime juice:

Take your first lime and juice it evenly over the seasoned salmon. The acid starts working right away and helps balance the spice.

Bake until just cooked through:

Slide everything into the oven for 12 to 15 minutes; you're looking for salmon that flakes easily when you test it with a fork and has just turned opaque in the center. Don't overbake or it gets dry.

Finish with fresh garnish:

Pull it out, scatter your cilantro or parsley over top, and arrange thin lime slices on each fillet. This final touch adds color and a hint of brightness right at the table.

There's something about salmon that makes people feel like you've done something fancy, even when it's genuinely this straightforward. My mom tasted this once and started making it herself every Thursday, which is the highest compliment anyone's ever paid to my cooking.

Why This Works as a Quick Weeknight Dinner

The beauty of this recipe is that it respects your time while delivering something that tastes considered. There's no browning step, no complicated sauce, just seasoning and heat doing all the work while you set the table or pour a drink. It's one of those rare dishes that actually tastes better when you're not overthinking it.

Playing with Heat Levels

Cajun seasoning has personality, and that personality varies wildly between brands. Some are basically paprika and garlic with a whisper of heat, while others will make your eyes water. Before you commit to the full 2 tablespoons, open your jar and taste a tiny pinch; if it catches you off guard, start with a tablespoon and build from there. You can always add more heat, but you can't take it back.

Serving Suggestions and Pairings

The lime and cilantro make this salmon lean toward brighter sides, so think steamed jasmine rice, roasted asparagus, or a crisp green salad with lime vinaigrette. If you're feeling it, a cold Sauvignon Blanc or light wheat beer beside your plate turns a regular dinner into something that feels like a little occasion. The warm spice pairs beautifully with cool, slightly acidic drinks.

• Leftover salmon keeps well for two days and makes an excellent addition to salads the next day.
• You can prep everything up to the baking step in the morning and bake right before dinner.
• Double the recipe easily by just adding more fillets to the pan with enough space between them.
