Freezing Food

Ever since becoming a parent, I have relied on my freezer to help me make the most of my time in the kitchen. I regularly freeze fresh food to ensure it doesn’t go bad, and I freeze cooked and prepared food to use in future weeks.

This helps me to keep my food budget in check since we waste less food. It also helps me cook less since I have a freezer stash to rely on.

This guide will take us through the basics of freezing, my favorite containers, tips for freezing produce, tips for freezing prepared and cooked foods, how to thaw foods for best results, and much more.

Freezing Food Preservation

Freezing food is one of my favorite ways to preserve food because it’s so easy. In most cases, you don’t have to do much to the food to make it ready to freeze and it’s so easy to use it whenever you’re ready.

I love this as a way to freeze fresh produce that we won’t be able to eat before it goes bad; store partial batches of baked goods for future weeks; store leftovers until we’re ready to eat them; and meal-prep foods like smoothies and pancakes.

Freezing Food Containers

You don’t need much to freeze food, but a few basic containers and bags can help. These are my favorites:

  • Plastic freezer bags: Grocery store freezer bags are remarkably effective, efficient and affordable options for freezing food. I make a DIY vacuum seal by sealing the bag almost all the way, then inserting a straw and sucking out the air and quickly sealing fully. Removing as much air as possible lessens the likelihood of freezer burn.
  • Reusable storage bags: Bags from brands like Stasher and Target are great for reusing. It can be more of a challenge to remove all the air from silicone bags since they are thicker and don’t seal as quickly, but do your best to press down the bag to remove air.
  • Ice cube trays: You can freeze all sorts of food in an ice cube tray and pop them out for easy use after. Foods that work this way include smoothies, baby food purees, applesauce, broth, tomato sauce, pesto, milk, and more.
  • Souper Cubes: This product is a slightly larger version of an ice cube tray that allows you to freeze 1-2 cup portions of foods in a silicone tray. They are really handy for soups, broths, and even mirepoix.
  • Freezer-safe food containers: Freezer-safe containers from brands such as Ziploc and Rubbermaid are great for freezing larger portions of soups, stews, chilis, pasta sauces, and more.

How to Freeze Food, Step-by-Step

Here’s the general process for how to freeze foods so you know what to expect. This will vary slightly according to the food you plan to freeze, so see the more specific info below.

  1. Wash and dry the food or prepare it according to your recipe.
  2. Let cool, if needed.
  3. Add to a freezer bag or container in a single layer. Separate subsequent layers with parchment paper or wax paper, if needed, to prevent the food from sticking together. (If freezing produce, I recommend simply freezing in one flat layer. Remove as much air from the container as you can.
  4. Freeze until ready to use.

Frequently Asked Questions

Which foods are safe to freeze?

You can freeze almost any food. Some foods will not taste great (in terms of texture) once thawed such as lettuce or other fresh greens, cucumbers, eggs in shells, canned foods, and any food that is no longer fresh.

Which foods should not be frozen?

Raw vegetables such as lettuce and potatoes, mayonnaise and eggs in shells, canned foods, and any food that is not fresh should not be frozen.

How long can you keep frozen food?

The length of time you can keep frozen foods depends on the food. The USDA has a chart that may help.

Is it OK to freeze cooked food?

According to the USDA, yes. “Once food is thawed in the refrigerator, it is safe to refreeze it without cooking, although there may be a loss of quality due to the moisture lost through thawing. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods. If previously cooked foods are thawed in the refrigerator, you may refreeze the unused portion. Freeze leftovers within 3-4 days. Do not refreeze any foods left outside the refrigerator longer than 2 hours; 1 hour in temperatures above 90 °F.”

Tips for Freezing Prepared Food

You can freeze almost any prepared food, whether it’s cooked or baked, apart from salads. (Raw veggies will not thaw to the same texture.) Generally speaking, the process is as follows:

  1. Let the food cool if it was hot. (If heat is trapped in a container or bag it will release steam, which can turn to condensation. Those water drops can freeze onto the food, causing it to become icy.)
  2. Add it to a storage container or freezer bag. If using a freezer bag, try to add it in one layer and remove as much air as possible.
  3. Freeze.

How to Freeze Pouches

You can freeze almost any baby food pouch (or toddler pouch) for future use if you want to batch-prep a few at a time or to store leftovers.

Simply place into the reusable pouch and seal according to the manufacturer’s directions. Freeze. To thaw, place frozen right into a lunch box (it will thaw in 2-3 hours if at room temperature) or overnight in the fridge.


How to Thaw Frozen Food

For baked goods such as muffins or Breakfast Bars, you can thaw overnight in the fridge or at room temperature. Or thaw in 15-second increments on a heat-safe plate in the microwave. Do not overcook.

For meatballs or other frozen meat, you can simmer in sauce (such as marinara sauce) or heat in a 375-degree-F oven for 4-6 minutes, or briefly in a 375-degree-F air fryer.

You can add frozen fruit directly to smoothies, oatmeal, or baked goods. Or turn frozen apples into Cinnamon Apples.

Best Tips for Success

  • Let food cool before freezing to lower the amount of ice that may form in the container or bag.
  • Remove as much air as possible from freezer bags using your hands or a straw.
  • Freeze foods in freezer bags in one single layer—or use parchment paper or wax paper between layers—so the food doesn’t freeze together.
  • Thaw prepared foods overnight in the fridge or in 15- to 30-second increments in the microwave.
  • Freeze half batches of Breakfast Bars, Cereal Bars, Fig Bars, Granola Bars, Energy Bites, Vegetable Broth, and more for future weeks.
