As much as I love canning (and I really do!), sometimes it’s nice to have an easier, quicker way to preserve food. That’s why I’ve grown to love freezing as a food preservation method. It’s fast, doesn’t require special equipment, and is a great way to capture the flavor of fresh produce—especially when you have a small harvest or limited time.

This recipe, adapted from Angi Schneider’s book The Ultimate Guide to Preserving Vegetables (Amazon), is a perfect example of that. If you’ve followed my blog for a while, you know I’m a big fan of Angi’s book, Pressure Canning for Beginners and Beyond (see my other blog posts using her canning recipes!).

But today, we’re talking about freezing—and not just individual veggies. I’ve started freezing more side dishes lately, and I have to say, it’s quickly becoming a favorite. It’s a great option when I buy produce and don’t have time to can or dehydrate right away. And in this case, I had just enough ripe tomatoes from my small urban garden to make this side dish (plus a few for eating fresh!).

Freezing Green Beans and Tomatoes is a Step Up from Basic Frozen Green Beans!

This green bean and tomato dish is different from the frozen green beans you grab at the grocery store. It’s simmered briefly in tomato sauce with onions and chopped tomatoes—giving it much more flavor and making it a ready-to-go side dish straight from the freezer.

Ingredients

This recipe requires just 4 simple ingredients – green beans, onions, tomatoes, and tomato sauce.

Here’s a quick overview of what you’ll need:

  • Tomato Sauce – You can use home-canned or store-bought tomato sauce.
  • Green Beans – Snap beans, trimmed and cut into bite-sized pieces. If needed, string the beans.
  • Chopped Onions – Adds great flavor to the mix.
  • Chopped Tomatoes – Fresh, ripe tomatoes work best here.

Prepping the Ingredients

Green beans with the ends trimmed off
Cut off the ends of the green beans and discard any that are damaged.

Start by trimming the ends off your green beans.

If your beans need stringing, go ahead and do that too. I’ll embed a helpful video in the post for anyone unfamiliar with how to string beans.

Cut the beans into 1- 2-inch pieces and prep your other ingredients.

You can cut your green beans into any size pieces you like. I like mine to be at least 1″ long, and up to 2″ long.

Cooking the Green Beans and Tomatoes Mixture

I love this simple combination of the ingredient you need for freezing green beans and tomatoes. So simple, but so good!

You can heat the tomato sauce first and then add the vegetables, or do what I did and add everything to the pot at once.

Bring it all to a boil, then lower the heat and let it simmer for 3 minutes. That’s the same amount of time you’d blanch green beans if freezing them solo—so no need to blanch separately.

Cooling and Packaging

Let the green bean and tomato mixture cool before dividing it into freezer-safe containers or zip-top bags. Portion sizes are flexible—choose what works best for your household.

To make bag-filling easier, I fold the top of the bag over a wide-mouth quart mason jar.

This front view gives you a little better look at how full they were. Note that since some of the bag is above the rim of the jar, there is still a decent amount of room in the bags, so you could put more in than I did if desired.

While I had let the green beans cool before putting them into the bags, there was enough warmth in them that I let them cool a bit more before moving on to the next step.

Once filled, I press out the air, seal the bags, and lay them flat.

You can see there was still a tiny bit of condensation, but I went ahead and laid them flat and squeezed out as much air as possible before putting them into the freezer.

Flash freezing the bags (not stacked) on a baking sheet helps prevent sticking. Once frozen, I stack them in the freezer with other ready-made side dishes.
