Hello, fellow food enthusiasts! Today, I want to share with you my process of dehydrating some of my favorite frozen veggies. This method is perfect for food storage and emergency prepping.

I often use dehydrated broccoli in various dishes, such as my broccoli cheese casserole, and find it to be a versatile ingredient that can easily be rehydrated.

Dehydrating frozen vegetables not only saves space in the freezer but also offers a convenient and long-lasting food storage option.

Sure, you can have fresh or frozen broccoli, but with dehydrated veggies, you can create a variety of meals, such as broccoli soup, casseroles, or just simple cooked broccoli.

Best Time to Buy Frozen Vegetables

The best time to stock up on frozen veggies is around Thanksgiving when stores like Kroger offer them at great prices. I usually buy several bags of my favorite vegetables, such as broccoli, spinach, and mirepoix mix (carrot, celery, and onion), and dehydrate them.

Dehydrating frozen vegetables saves a lot of work compared to using fresh ones, as there’s no need to cut, steam, or blanch the veggies before dehydrating. The packages come ready for you, which is simply amazing.

What Frozen Veggies to Dehydrate

One of my go-to blends I use in many recipes is a mixture of carrot, celery, and onion. While you might wonder why I don’t just use fresh produce, dehydrating already cut and mixed vegetables saves time and effort.

Plus, it frees up valuable freezer space, which I need for my other food storage, because dehydrated vegetables significantly reduce their volume, allowing you to store a large amount of food in a small space, making storage a breeze.

Just to give you an idea, a 12-ounce bag of mixed veggies, once dehydrated, reduces to a small, compact jar.

Dehydrating Process Using a Food Dehydrator

Now, let’s get started on the dehydrating process. I use an Excalibur dehydrator, which I find to be efficient and reliable so I highly recommend it. It’s perfect for dehydrating because it has various settings for different types of food, including vegetables, fruits, herbs, and meats. 

To begin, remove the front panel of the dehydrator and start filling the trays with the frozen veggies. Make sure to spread them out evenly, as this will help them dry faster. You can also break up any frozen clumps after an hour or so once they’ve softened, as the vegetables thaw slightly.

After filling the trays, set the temperature to 125 degrees Fahrenheit for vegetables and the timer for 12 hours. Plug in the dehydrator, and you’re good to go. The Excalibur machine does make some noise while running, but I find it to be tolerable.

Once done, you’ll be left with dehydrated veggies that are ready for storage or meal preparation. You can even customize your dehydrated veggies by adding seasonings like garlic, salt, pepper, or herbs such as parsley and sage. This makes them even more recipe-ready when you need them.

Afterwards, you can store them in vacuum-sealed jars, adding any additional seasonings or herbs if desired. This method is perfect for creating meal-ready jars, which can be a lifesaver during emergencies or times when you need to whip up a quick meal.

Dehydrating is an easy and rewarding way to store food, providing a sense of assurance that you’ll have healthy and delicious meals available even in challenging situations.

Whether it’s due to a power outage, job loss, or helping a friend in need, having dehydrated veggies on hand can be a valuable asset in your pantry.
