Delicate cod gets the full flavor treatment with this enlivening pepper sauce. Bring a burst of vibrant, Mediterranean-inspired flavor to your table with a healthy, protein-packed skillet that perfectly balances sweet and tangy notes. This Sweet & Sour Pepper Cod features flaky, tender Alaskan cod fillets seasoned with salt and freshly ground pepper, nestled in a rich, chunkier pan sauce. The flavor base begins by sautéing a large sliced onion, minced garlic, and aromatic coriander seeds in extra virgin olive oil, alongside an optional touch of warm curry powder. Slices of sweet red and yellow bell peppers are tossed into the pan with canned chopped tomatoes and simmered with bay leaves. The signature sweet-and-sour depth is captured through a blend of crisp cider vinegar and zero-glycemic erythritol, creating a beautifully texturized, complex sauce that coats the delicate white fish.
Traditional takeout sweet-and-sour dishes are unfortunately filled with metabolic hurdles. They typically feature protein coated in heavy cornstarch batters, deep-fried in inflammatory refined oils, and smothered in a thick glaze packed with high-fructose corn syrup, white sugar, or commercial pineapple juice. When served over standard white rice, this fast-digesting combination causes an immediate blood glucose surge and a demanding insulin spike. This recipe relies on an intelligent, clean cooking method. By letting the natural volume of high-fiber peppers and tomatoes build the body of the dish, sweetening with zero-calorie erythritol, and omitting flour or starch thickeners, you can enjoy a comforting, tangy meal while keeping your blood sugar entirely stable.

Synergistic Effect
The absolute metabolic control engineered into this skillet dish relies on the combination of ultra-lean marine protein, healthy lipids, and an abundance of structural vegetable fiber. Cod is an exceptional source of pure amino acids, which inherently delay the rate at which your stomach empties. When paired with the plentiful insoluble fibers from the simmered bell peppers and onions, as well as the monounsaturated fats in the olive oil, digestion slows down to a steady, controlled crawl. This comprehensive delay ensures that the natural carbohydrates present in the tomatoes and sweet peppers are broken down gradually, ensuring a beautifully flat post-meal glucose line.

Ingredients
Instructions

Preheat the oven to 300 degrees F / 149 C. Line a pan with foil and oil the foil. Sprinkle the fish with salt and pepper and lay on the foil.

Heat the oil in a large skillet over medium heat and add the onion and coriander seeds. Cook, stirring often, until the onion is tender, about 5 minutes. Add the bell peppers and a generous pinch of salt. Cook, stirring often, until the peppers and onions are soft, another 8 to 10 minutes. Stir in the garlic and curry powder.
