Batch cooking: preservation times according to the type of dish
When you cook several dishes in advance, not all of them keep the same in the refrigerator; the times vary depending on the main ingredient and the presence of sauces.
Cooking in large batches saves considerable time, but there's a significant drawback: not all dishes keep equally well. A bowl of rice, roast chicken, fish, yogurt sauce, or pre-cooked vegetables won't all last the same amount of time in the refrigerator. The right approach isn't to store everything for five days without a second thought, but rather to check each dish based on its specific characteristics. Cooked grains, such as rice, pasta, quinoa, or couscous, are very practical for preparing bases in advance, but they need to cool quickly. Spread them out in a shallow container to cool faster and then store them in the refrigerator in an airtight container.
Dishes containing meat, fish, or eggs should be placed at the beginning of the meal plan. Cooked fish is best eaten at first meals. Chicken, meatballs, or other meat dishes can be stored for a few days, but they shouldn't be forgotten at the back of the refrigerator. Hard-boiled eggs are convenient, but it's best not to eat them every day of the week. They should be cooled, refrigerated, and eaten within the first few days. Cooked vegetables are very useful for preparing quick meals, but vegetables with a high water content can release liquid and lose their texture. Legumes, such as chickpeas, lentils, and beans, are a good base and keep well in simple dishes, but their flavor becomes more delicate when combined with fresh sauces.
Sauces can completely change how a dish keeps. A cooked tomato sauce doesn't have the same texture as a yogurt, mayonnaise, egg, or cream cheese sauce. To avoid unpleasant surprises, prepare sauces in separate small containers. Add them only when you're about to eat. This also improves the texture: grains stay firmer, vegetables release less water, and proteins retain their shape better. A hot dish shouldn't be left at room temperature for hours; divide large quantities into smaller, shallow containers so they cool down faster. When several containers look alike, it's easy to forget what was prepared and when. A simple label with the dish's name and the date allows you to use the most perishable ingredients first.
