High Fructose Corn Syrup Free Paleo Blackened Mahi-Mahi
Bold, smoky, and deeply satisfying, this blackened mahi-mahi is the kind of weeknight dinner that feels like it came from a restaurant kitchen. The secret is a homemade spice blend — smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne, and black pepper — pressed firmly into each fillet before it hits a screaming-hot cast-iron skillet. That high-heat sear is what builds the gorgeous, dark crust that makes blackened fish so irresistible. Because every single ingredient here is a whole food or pure spice, there's zero chance of sneaking in any processed sweeteners or corn-derived additives that often hide in store-bought seasoning packets and marinades. Avocado oil handles the high heat beautifully, and a squeeze of fresh lime at the end cuts right through the spice with a bright, clean finish. It's naturally grain-free and fits a paleo lifestyle without any substitutions or workarounds — just real ingredients doing exactly what they're supposed to do.
