Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Catfish fillets
- Provide the mild, flaky white fish that forms the base of the dish.
- Tomatoes
- Add moisture and acidity that keep the topping juicy under the broiler.
- Cheddar cheese
- Melts and browns over the topping, adding richness and savoury flavour.
- Onion
- Adds sharp aromatic flavour and sweetness that mellows as it cooks.
- Olive oil
- Carries the flavours of the marinade and helps the fish brown and stay moist.
The step that matters
Broiling the fillets with the topping. Fish cooks quickly under high heat and can dry out or overcook, so watch closely during the second broil. Placing the fillets about 4 inches from the heat gives even cooking and browning of the cheese without burning the thin fish.

Fit is the average pairing score against catfish, lemon, olive, sauce, tomato, onion, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
