Chili Lime Mahi-Mahi with Blackened Broccoli (15 Min)
This chili lime mahi-mahi with blackened broccoli is the healthy weeknight dinner that actually tastes exciting. Flaky white fish brushed with a spicy-sweet chili lime sauce, served with caramelized broccoli that soaks up all those incredible flavors.
Tender mahi-mahi fillets cooked in a vibrant sauce made with fresh lime juice, cilantro, honey, and just enough heat from red pepper flakes and chili powder. Then you toss steamed broccoli in that same sauce and char it in the hot skillet until it’s crispy and caramelized on the edges.

The genius here is using one sauce for everything – it flavors the fish while it cooks, then transforms the broccoli into something way more interesting than plain steamed vegetables. Everything comes together in one skillet in about 15 minutes, which makes this perfect for those nights when you want something healthy but can’t deal with complicated recipes.
Mahi-mahi is ideal for this because it’s firm enough to handle flipping but mild enough to let that bright, zesty sauce shine. Can’t find mahi-mahi? Halibut or snapper work just as well.
Perfect for Lent Fridays, healthy weeknight dinners, or anytime you want something light and flavorful without a lot of fuss.

To make this Chili Lime Mahi-Mahi, you’ll need:

- Basting Brush – For applying sauce to fish
- Fish Spatula – Makes flipping easier (but regular spatula works)
Chili Lime Mahi-Mahi with Blackened Broccoli (15 Min)
Ingredients
Method
- Steam broccoli: Place broccoli florets and water in microwave-safe bowl. Cover and microwave on high for 2-3 minutes until crisp-tender (check at 2 minutes). Transfer to strainer to drain. Set aside.
- Make sauce: While broccoli steams, whisk together lime juice, cilantro, ÂĽ cup olive oil, honey, red pepper flakes, chili powder, cumin, garlic powder, salt, and pepper in a medium bowl. Set aside. (Reserve remaining olive oil for cooking fish.)
- Cook fish: Heat remaining olive oil in large nonstick skillet over medium heat. Pat mahi-mahi fillets completely dry with paper towels. Add to hot skillet and brush tops generously with chili lime sauce.
- Cook 4-5 minutes without moving. Carefully flip fillets and brush exposed side with more sauce. Cook another 3-4 minutes until fish is opaque and flakes easily with a fork.
- Transfer cooked fish to a plate and set aside.
- Blacken broccoli: Toss steamed broccoli with remaining chili lime sauce. Add to the same hot skillet. Increase heat to medium-high. Cook, stirring frequently, until broccoli is charred and caramelized, 3-4 minutes.
- Return fish and any accumulated juices to skillet. Remove from heat and serve immediately.
Tips & Variations
Supper & Sage Tip: Pat the fish COMPLETELY dry before adding to the skillet. Wet fish = sticking + steaming instead of searing. Dry fish = beautiful golden crust that releases easily when it’s ready to flip.
For perfect fish:
- Room temperature fish cooks more evenly – pull from the fridge 15 minutes before cooking
- Don’t move the fish while it cooks – let it develop a crust
- Fish will release naturally from the pan when ready to flip
- Opaque and flakes easily = done
- Slight translucency in very center is okay – carryover cooking will finish it
Fish substitutions:
- Halibut (cook 1-2 minutes longer, thicker fillets)
- Snapper (same timing as mahi-mahi)
- Cod (same timing, more delicate)
- Sea bass (cook 1 minute longer)
Broccoli tips:
- Don’t skip the microwave steam – raw broccoli won’t char properly in 3-4 minutes
- Frozen broccoli works great (might need 30 seconds more microwave time)
- Get the skillet HOT for proper blackening
- Stir frequently but let it sit long enough to get char marks
Heat adjustments:
- Mild: Use ÂĽ teaspoon red pepper flakes
- Medium (as written): ½ teaspoon
- Spicy: ¾ teaspoon or add fresh jalapeño to sauce
- Extra heat: Serve with hot sauce on the side
Make it a meal:
- Serve over rice or quinoa
- With cauliflower rice for low-carb
- Alongside roasted sweet potato
- Over mixed greens for a warm salad
Frequently Asked Questions
Q: Can I use a different vegetable instead of broccoli?
A: Yes! Asparagus, green beans, or Brussels sprouts all work. Adjust steaming time accordingly.
Q: My fish stuck to the pan. What happened?
A: Fish wasn’t dry enough, pan wasn’t hot enough, or you tried to flip too early. Let it cook undisturbed until it releases naturally.
Q: Can I grill the fish instead?
A: Absolutely! Grill over medium-high heat, brushing with sauce while cooking. Char the broccoli in a grill basket.
Q: How do I know when mahi-mahi is done?
A: It should be opaque throughout and flake easily with a fork. Internal temp should reach 145°F.
