This is a simple recipe for chili rubbed fish. All you do is sprinkle the seasonings and broil it! I usually use this rub on salmon, but I also use it on white fish like Mahi Mahi pictured here. Ingredients:
chili powder
paprika
onion powder
garlic powder
salt
Olive Oil spray for finish
Directions: Preheat broiler on low. Set rack in middle of oven. If you have a second rack, I use this to roast asparagus while the fish cooks under the broiler. Why asparagus? Because its fast to bake and I like a little crunch on mine. Eyeball all the seasonings. I first lightly salt the fish. Then coat is with the rest of the seasonings. I go heavy on the chili powder! Then spray tops of seasoned fish with olive oil spray. Place fish on top rack. Broil for about 4-5 min, then switch broiler to high. Broil until fish is done, maybe another 4 minutes, depending on the fish. You can start with broiler on high if you have thinner fish filets. You will get the crunchy rub without overcooking your fish. Top finished fish with store bought pico de gallo!
