How to Prepare, Pre-Cook and Store Vegetables in the Fridge

You can prepare vegetables the night before cooking them by washing and cutting or chopping them, then storing them in the fridge in an airtight container. You may also want to pre-cook vegetables for your recipes to save you time in the kitchen.

Most pre-cooked vegetables will keep in the fridge for several days if stored correctly. If stored incorrectly, they may spoil faster or become soggy.

There are several ways to pre-cook vegetables. Choose from the methods below.

Pre-cooking vegetables with the blanch and shock method is one way to speed up the cooking process for recipes you'll be making with them. Blanching is the process of immersing food in boiling water for a short time, and shocking required submerging the vegetables in ice water immediately after. This helps preserve the vegetables' color and texture but does not significantly affect their nutrient content.

Cook vegetables in boiling water for two to four minutes, or until crisp-tender, then transfer to ice water until they are no longer warm to the touch. Be careful not to over-blanch your veggies, or they'll lose some vitamins.

You can refrigerate pre-cooked veggies for three to four days.

Roasting vegetables adds a more unique flavor than the blanching and shocking process. This method imparts a nutty flavor and intensifies the natural sweetness in vegetables, such as yams and green beans.

Just season your veggies with healthy cooking oil and any spices you like, place them on a lined baking sheet with parchment paper and roast them in your oven at 475 degrees Fahrenheit until tender and brown around the edges.

Cooking times will vary depending on the size and type of your vegetables. Once they're out of the oven, allow them to cool, store them in a plastic container and refrigerate overnight.

Of all vegetable dishes, mashed potatoes are hard to make ahead and store. Once chilled, fully cooked mashed potatoes can turn gooey or dry out.

To avoid this, try microwaving whole potatoes for 16 minutes on high and flipping them halfway through the cooking process. Then, cook your potatoes in a 350-degree Fahrenheit preheated oven for 30 minutes. Let the potatoes cool, cut them in half and scrape the flesh. Then, you can refrigerate the potato flesh overnight and when you're ready to serve, simply warm them in the microwave and mix in any flavorings, such as Greek yogurt, butter or salt.

You can safely and easily prepare vegetables and store them in the fridge overnight before using them in your favorite recipes.

Prepping ahead means washing, peeling (if needed), and cutting, chopping, slicing or dicing your veggies according to the recipes you'll be using them in. After that, it's as simple as storing the vegetables in an airtight container and placing them in the fridge overnight.

Cooked vegetables stored properly in an airtight container will stay good in the fridge for at least three to four days, per the USDA. Some chefs and food experts say cooked veggies last as long as seven days with proper storage.

The amount of water in certain types of veggies may cause them to degrade in texture. Vegetables with a high water content, such as zucchini, tomato, celery, asparagus, mushrooms, cabbage and bell peppers may only last up to five days cooked. Veggies with lower water content, including spinach, peas, celery, cauliflower and potatoes may last longer.
