I love being able to grab a bag of vegetables from the freezer and turn it into a quick side dish or an easy lunch.

Broccoli, cauliflower, and carrots taste delicious sautéed with a little butter, garlic, salt, and pepper. They can also be added to soups, casseroles, stir-fries, and sheet-pan meals.

Making your own frozen vegetable mix is a great way to preserve garden produce, use vegetables purchased in bulk, or save food before it goes to waste.

The process is simple, but each vegetable must be blanched for the correct amount of time before freezing.

Why Vegetables Should Be Blanched Before Freezing

Blanching means placing vegetables in boiling water for a specific amount of time and then cooling them immediately in ice water.

According to the National Center for Home Food Preservation, blanching slows or stops the enzymes that can cause frozen vegetables to lose their color, flavor, and texture.

Blanching time matters. Under blanching can be worse than not blanching at all, while over blanching can affect the vegetables’ flavor, color, texture, and nutrients.

Broccoli, cauliflower, and sliced carrots do not all require the same amount of time, so we will blanch them separately.

What You Will Need

Gather everything before you begin:

• Fresh broccoli
• Fresh cauliflower
• Fresh carrots
• A large pot with a lid
• A blanching basket or slotted spoon
• A large bowl of ice water
• Clean kitchen towels
• Freezer bags or freezer-safe containers
• Permanent marker or freezer labels

Choose vegetables that are fresh, firm, and free from spoilage.

Step One: Wash and Prepare the Vegetables

Wash all the vegetables thoroughly.

Cut the broccoli into florets no larger than approximately 1½ inches across. Remove any tough or woody portions of the stems.

Cut the cauliflower into florets approximately one inch across.

Peel the carrots, if desired, and cut them into slices, small sticks, or uniform pieces.

Keeping the pieces close to the same size helps them blanch and cook more evenly.

Step Two: Prepare the Boiling Water and Ice Bath

Fill a large pot with approximately one gallon of water for each pound of prepared vegetables.

Bring the water to a vigorous boil.

While the water is heating, fill a large bowl with cold water and plenty of ice. The vegetables will go directly into the ice water after blanching to stop the cooking process.

Step Three: Blanch Each Vegetable for the Correct Time

The vegetables should be blanched in separate batches because their recommended blanching times are different.

Broccoli

Place the broccoli in the boiling water, cover the pot, and wait for the water to return to a boil.

Once the water returns to a boil, blanch the broccoli for three minutes.

Cauliflower

Place the cauliflower in the boiling water, cover the pot, and wait for the water to return to a boil.

Once the water returns to a boil, blanch the cauliflower for three minutes.

Carrots

Place sliced, diced, or lengthwise carrot pieces in the boiling water, cover the pot, and wait for the water to return to a boil.

Once the water returns to a boil, blanch the carrots for two minutes.

Small whole carrots require five minutes, but sliced or diced carrots only require two minutes.

Do not begin timing until the water returns to a boil after adding the vegetables.

Step Four: Cool the Vegetables Immediately

As soon as each blanching time is complete, transfer the vegetables directly into the ice water.

Allow them to cool for approximately the same amount of time they were blanched.

Cooling the vegetables quickly stops the cooking process and helps protect their color and texture.

Once the vegetables are completely cool, drain them thoroughly.

Step Five: Dry the Vegetables

Spread the vegetables on clean kitchen towels and allow them to drain and dry well.

Removing excess water helps reduce ice crystals and keeps the vegetables from freezing into one large block.

Handle the blanched vegetables carefully so they do not become crushed or broken.

Step Six: Combine and Package Your Vegetable Mix

Once the vegetables are cool and dry, combine the broccoli, cauliflower, and carrots in whatever proportions your family prefers.

Package the mixture in meal-size portions.

I like making smaller bags because I can pull out exactly what I need without thawing more vegetables than we will use.

Press excess air from freezer bags before sealing them. If you use freezer-safe containers, leave as little empty space as practical.

For vegetables that are easier to pour out a little at a time, spread them on a baking sheet and freeze until firm before transferring them to freezer bags.

Step Seven: Label and Freeze

Label every package with:

• Broccoli, cauliflower, and carrot mix
• The date it was frozen
• The approximate amount in the package

Place the packages in the coldest part of your freezer so they freeze as quickly as possible.

Once frozen, stack or organize the bags so you can easily see what you have.

How to Use Your Frozen Vegetable Mix

You can cook these vegetables directly from frozen. There is usually no need to thaw them first.

Use your frozen vegetable mix in:

• Soups and stews
• Stir-fries
• Casseroles
• Sheet-pan meals
• Pasta dishes
• Roasted vegetable dishes
• Quick side dishes
• Vegetables sautéed with butter and garlic

Because the vegetables were blanched before freezing, remember that they are already partially cooked. Watch them carefully so they do not become too soft.

Save Money by Preserving What You Already Have

Freezing vegetables is especially helpful when you find a good seasonal price, have an abundant garden harvest, or notice fresh vegetables that need to be used soon.

However, buying extra food only saves money when your family will eat it and you preserve it before it spoils.

Package your vegetables in realistic portions, label everything clearly, and remember to use what is already in your freezer.

That is strategic shopping: buying with a plan, preventing waste, and turning today’s food into future meals.
