Benefits of eating frozen vegetables

All the nutrition of fresh vegetables

There is a misconception that “fresh is best.” However, frozen vegetables have just as much nutrition to offer as their fresh counterparts.

Nutritional composition depends on the vegetable but in general, frozen vegetables are:

  • Low in sodium
  • Good sources of fiber
  • Rich in minerals like calcium, magnesium and potassium and vitamins like A,C,E, K and B-vitamins.

Frozen vegetables are a great addition to a plant-forward diet because they offer all the benefits of eating fresh vegetables. 

Reduce food waste 

Frozen vegetables can help mitigate food waste in your kitchen because they keep much longer than fresh vegetables. 

Check the sell-by dates on the packaging and follow instructions. Typically frozen vegetables are “good” for at least six months after purchase. Make sure to keep them sealed to help prevent freezer burn and off-flavors.

Experiment with new vegetables. 

Opting for a frozen variety of a vegetable you want to experiment with is a great way to try new plant-based foods. Perhaps the vegetable is hard to peel or you don’t know to season it with, then try the frozen version instead!

Cook for one or two people with ease. 

If you are only cooking for yourself or just one other person, you may end up having to buy more fresh produce than you actually need. 

This is not only expensive but also could lead to unintentional food waste. But using frozen vegetables and only defrosting what you need is a great way to save money and cook small batches. 

Enjoy out-of-season flavors. 

Feel like butternut squash in July or cherries in November? Then shop in the frozen section and don’t miss out on the flavors you are craving. 

Save time in the kitchen. 

Some nights you just don’t have time to wash, peel and chop. That’s where frozen vegetables can come in handy. All the prep work is done for you. Plus, frozen veggies are typically par-cooked so they will cook quicker than raw vegetables.

Save money on your grocery bill. 

The opportunity for less food waste and shopping during sales makes frozen vegetables an affordable option.

The direct savings between raw, fresh vegetables and frozen vegetables are a little hard to calculate because it depends on region, season and current pricing. But I suspect they would end up being less expensive.

Reduce the effort it takes to cook. 

If you (or someone you care for) struggles with chopping and peeling vegetables due to arthritis or another chronic condition, then frozen vegetables are a great solution. 

No fancy equipment needed.

Cooking in a college dorm with only a microwave? Not great with a chef’s knife? Then frozen veggies are perfect for you!

What goes well with frozen vegetables?

Now that we know that frozen vegetables have many health, time-saving and money-saving benefits, let’s talk about what you can do with them in the kitchen! 

Frozen vegetables can be used in most places where fresh vegetables can be used, with a couple of exceptions. Here are some ideas to get you thinking about how to cook frozen vegetables.

  • Pair with proteins like meat, seafood or tofu for a complete meal. 
  • Toss with pasta for a plant-forward meal
  • Put on top of pizza
  • Puree with frozen fruit for a smoothie
  • Pulse with beans for a flavored hummus or bean-dip
  • Add into stir-fries
  • Combine with potatoes for breakfast hashes
  • Bake into pancake, muffin or biscuits
  • Use in vegetarian entrees and casseroles like shepherd’s pie and spanikopita 
  • Stir into soups, chilis and stews 

Different types of frozen vegetables

Frozen vegetables are simply vegetables that have been partially cooked and then frozen very quickly. 

Frozen vegetables can be found as a single vegetable (like a bag of frozen peas) or as part of a blend with other frozen vegetables aka “mixed vegetables”. There are also frozen vegetables that are combined with grains and sauces. 

You can find frozen vegetables pureed, chopped, whole, riced and even spiralized. 

The selection and variety will depend on your grocery store, but you can likely find any vegetable you desire in frozen form. This includes:

  • Starchy vegetables like peas and corn
  • Root vegetables like cassava, carrots and rutabaga
  • Squash like butternut and zucchini
  • Aromatics like pepper, onions, ginger and garlic
  • Hearty greens like spinach, collard greens and mustard greens

How to shop for frozen vegetables

Now that your mouth is watering, let’s cover some tips for shopping for frozen vegetables.

Store brand versus name brand. I almost always reach for store brand frozen vegetables because they are less expensive than name-brand frozen vegetables. 

Organic versus conventional. Organic food can be a controversial topic but remember that organic produce is not healthier for you from a nutrition perspective. 

Seasoned versus unseasoned. If you are following a special diet like gluten-free, vegan or low-sodium, be sure to check the nutrition label for ingredients in the seasoning/sauce that may not align with your dietary goals.

If there are other considerations you have when shopping, be sure to talk to your dietitian.

How to cook frozen vegetables without them getting soggy

One of the biggest mistakes people make when cooking with frozen vegetables is boiling them.

Cooking with high heat and as little liquid as possible is the best way to avoid sogginess when cooking frozen vegetables. 

  • Sauteeing: quickly cooking the frozen vegetable in oil over high heat in a skillet.
  • Steaming or blanching: quickly cooking frozen vegetables with steam. Blanching involves stopping the cooking process by plunging the vegetables into ice water.
  • Roasting: tossing the vegetables with oil, placing on a sheet pan and baking in a hot oven of at least 400 degrees Fahrenheit.
  • Air-frying: air-frying is convection cooking in which food gets crispy without a lot of oil.
  • Microwaving: microwaving frozen vegetables in a small amount of water or other cooking liquid (like broth) is the simplest way to cook frozen vegetables
  • Pureeing: blending frozen vegetables into smoothies, dips and soups is a great way to use them.

Let’s address a couple other questions you may have related to how to cook frozen vegetables.

Should frozen vegetables be thawed before using?

It is generally best not to thaw frozen vegetables before cooking, unless the recipe specifies or you are pureeing the vegetable. 

When should you add frozen vegetables in the cooking process?

Many recipes will specify adding the frozen vegetables toward the end of cooking to avoid overcooking.

How to make frozen vegetables taste good

Besides the cooking method like we discussed above, how you season frozen vegetables when cooking can make a big difference.

When considering how to cook frozen vegetables, it is important to keep flavor and texture in mind. Consider salty, creamy, smoky, crunchy, fresh, sweet, sour and umami. 

Frozen vegetables do not need fancy ingredients to become flavorful. Here are some ideas for adding flavor to your frozen vegetables.

Herbs and spices

  • Fresh herbs like basil, cilantro, parsley and dill
  • Dried herbs like thyme and oregano
  • Zest from lemon, lime or orange
  • Minced or grated garlic
  • Fresh ginger 
  • Spices like paprika, turmeric, cumin, coriander, chili powder and curry powder
  • Salt and pepper

Fat and oils

  • Butter
  • Olive oil 
  • Sesame oil
  • Nut oils like walnut
  • Infused oils (homemade or from specialty markets)
  • Parmesan cheese


  • Soy sauce
  • Oyster sauce
  • Fish sauce
  • Coconut milk
  • Miso paste
  • Harissa
  • Tahini
  • Nut butters like peanut butter and almond butter
  • Pesto
  • Olive tapenade
  • Hot sauce


  • Brown sugar
  • Maple syrup
  • Honey
  • Molasses 


  • Chopped nuts
  • Toasted bread crumbs
  • Crushed-up crackers or croutons

How do you store frozen vegetables after they’ve been cooked?

Cool leftover frozen vegetables to room temperature and package in an air-tight container. Cooked frozen vegetables are likely safe to eat up to 3 days after cooking.
