Roasted White Fish & Potatoes
Ingredient allergen flags: Fish (cod)
Check actual labels and cross-contact. Allergen guidance and swaps
Crisp-edged potatoes and flaky cod cook on two oven trays.

Ingredients
- 1 1/3 lb (600 g) plain frozen cod fillets, thawed in the refrigerator
- 1 3/4 lb (800 g) potatoes, cut into 3/4-inch pieces
- 3 cups (400 g) plain frozen peas
- 2 Tbsp (27 g) olive oil
- 2 Tbsp (30 g) lemon juice
- 2 cloves (6 g total) garlic, minced
Method
- Heat oven to 425°F. Pat thawed cod dry; keep it separate from the vegetables. Toss potatoes with half the oil on one rimmed tray; roast 20 minutes.
- Put cod on a second rimmed tray, brush with the remaining oil and garlic. Season with salt and pepper to taste. Roast 10-15 minutes, until the thickest part reaches 145°F and is opaque and flakes easily. Keep roasting potatoes until tender and browned, about 30-35 minutes total.
- Cook peas according to the package, drain and divide with the cod and potatoes into four portions. Add lemon juice.
Allergy / dietary substitutions
Fish: replace cod with plain chicken breast; this adds no tracked major allergens, but cook it separately to 165°F. Check labels on frozen fillets and vegetables; coatings and sauces can add wheat, milk or soy.
Training-day additions
Add bread (adds wheat) or extra potatoes (no tracked allergens added).
Store / pack
Refrigerate promptly in shallow containers; use within 3 days. Reheat leftovers to 165°F. Pack cold with two ice sources. Cod is on the FDA/EPA 'Best Choices' list (F6, Sources). See safety on Keep good food safe.

How the nutrition estimates are made
Each recipe reports approximate calories, protein, carbohydrate and fat per equal serving of its stated base batch. P = protein; C = carbohydrate; F = fat.
One ingredient, one weighed amount
The source stores edible ingredient grams and a USDA FoodData Central SR Legacy record. Dry pasta, oats, rice and lentils use dry weights; raw and cooked meat use matching records. Water and measured seasonings are included.
The calculation
For each nutrient: multiply ingredient grams by the USDA value per 100 g, divide by 100, sum the batch and divide by servings. Round calories to the nearest 10 kcal and macronutrients to the nearest gram.
What can change the result
Brand, draining, natural variation and cooking losses affect the real meal. Canned black/white beans use cooked unsalted bean proxies. Red lentils use generic lentils. The method assumes all listed oil and edible food are consumed; it does not model nutrient retention or evaporation.
What the estimate does not claim
Sides, training-day additions, substitutions and allergy swaps are excluded. Sodium, vitamins and minerals are not reported. These are ingredient estimates, not laboratory results, an assessment of your whole diet or a daily intake target.
