This chili lime salmon is what quick weeknight dinners are made of — juicy, flaky salmon under a zesty chili-lime butter that hits salty, buttery, tangy, and warmly spiced in every bite. It takes 25 minutes start to finish and tastes like way more effort than it is.
The compound butter comes together in seconds while the oven preheats, and the whole tray is done in about 15 minutes of hands-off baking. Serve over rice, with a salad, or tucked into tacos — it's a formula you'll rotate all year.

Ingredients
For the salmon
- 4 salmon fillets (about 6 oz each), skin on or off
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Chili lime butter
- 4 tablespoons butter, melted
- Zest and juice of 2 limes
- 2 cloves garlic, minced
- 1 teaspoon chili powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon ground cumin
- 1/4 teaspoon salt
- Chopped fresh cilantro, to serve
- Lime wedges, to serve
Ingredient notes & substitutions
- Salmon fillets:
- Look for center-cut fillets of similar thickness so they cook evenly. Skin-on or off both work; skin crisps up beautifully at 400°F.
- Lime (zest + juice):
- Zest first, then juice. The zest carries perfumed oils; the juice adds bright acidity. Fresh limes only — bottled juice tastes flat.
- Chili powder:
- Warm, mild, and smoky — not the same as cayenne. Look for a blended chili powder (ancho-based is beautiful here).
- Smoked paprika + cumin:
- The two spices that make this taste distinctly Tex-Mex, not just salmon with lime. Both are worth having in the cabinet.
- Butter:
- Real butter melts into the salmon and carries all the citrus and spice flavors. Use unsalted so you control the salt.
Method
- 1
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment or foil.
- 2
Pat the salmon fillets dry and place them on the baking sheet. Rub with olive oil and season with salt and pepper.
- 3
In a small bowl, whisk the melted butter with the lime zest, lime juice, garlic, chili powder, smoked paprika, cumin, and salt.
- 4
Spoon the chili-lime butter generously over each salmon fillet.
- 5
Bake for 12 to 15 minutes, until the salmon flakes easily with a fork and reaches 145°F in the thickest part.
- 6
Top with fresh cilantro and serve with lime wedges, over rice or with a fresh salad.
Tips
- Pat the salmon dry so the butter and seasonings stick and the fillets don't steam.
- Zest the limes before juicing — you'll never get zest off a squeezed lime.
- Don't overbake — pull the salmon at 145°F for juicy, flaky fish; it keeps cooking a couple of degrees off the heat.
Variations to try
- Sub in trout, cod, or halibut — reduce bake time for thinner fillets.
- Add a drizzle of honey to the butter for a sweet-heat glaze.
- Make it into salmon tacos with slaw and avocado.
- Grill or air-fry instead of baking (400°F, 8 to 10 minutes).
Storage & make-ahead
Store leftover salmon in an airtight container in the fridge for up to 3 days. Reheat gently, covered, in a low 275°F oven just until warm — a hot reheat overcooks it. Leftover salmon is amazing flaked into a salad, tossed with pasta, or piled into tacos cold. Not a great candidate for freezing (texture suffers).
Frequently asked questions
- How do I know when salmon is done?
- It should flake easily with a fork and reach 145°F internal in the thickest part. If you don't have a thermometer, look for the flesh turning opaque all the way through and just starting to separate into flakes.
- Can I cook it on the grill?
- Yes — grill skin-side down over medium-high heat for 8 to 10 minutes, brushing with the chili-lime butter as it cooks.
- Is the skin on or off?
- Both work. Skin-on protects the flesh and crisps up beautifully; skin-off is easier to serve and lets the butter soak in more.
- What do I serve with chili lime salmon?
- Cilantro-lime rice, black beans, a fresh corn salad, or a simple green salad. It's also fantastic in tacos with slaw and avocado.
