Veggie Scrap Broth Ingredients

Vegetable Broth from Veggie Scraps Tips and Tricks
Why Make Veggie Broth from Vegetable Scraps?
Not only is homemade vegetable broth super delicious and healthier than store-bought (you can control the quality of the vegetables and the amount of sodium when making your own!), but it’s also a really great way to make the most of your produce, helping to avoid excess food waste.
So, why should we care about food waste anyway?
For starters, the food industry accounts for 25% of greenhouse gas emissions and is responsible for the destruction of ecosystems by way of air, water, soil, and noise pollution. Plus, the food industry consumes a quarter of our global freshwater use annually.
And for all of that energy, disruption, and pollution, only just over half of it is even consumed.
Additionally, food that goes to waste is sitting in landfills, creating tons of toxic methane, and food packaging is ending up as microplastics in our oceans.
With all of the strain the food industry puts on our environment, for 40% of it to go to waste is catastrophic.
Additionally, the waste itself becomes a problem. Though a lot of food waste is organic which may lead you to believe it will break down naturally into compost, it requires oxygen to complete this process.
This means that when food is sent to the landfill and does not have access to the oxygen it needs, it is no longer able to break down organically.
Instead, it eventually breaks down into mostly water and methane (a harmful greenhouse gas), further contributing to greenhouse gas emissions.
Green tip: Did you know that of the billions of pounds of food wasted annually, it is estimated that 50% of it happens in our homes? Make the most of your produce by using scraps to make your own vegetable broth!
How to Save Veggie Scraps to Make Vegetable Broth
Keep a freezer-safe gallon storage bag in your freezer where you can collect all your veggie scraps that you produce while cooking. Write the date on the bag the first time you add scraps to it, so you can track its age.
Green tip: Reduce your plastic waste by using these Reusable Storage Bags!
As you peel potatoes and carrots, core apples and onions, snap the tips off your asparagus, and trim the leaves off the stems of your herbs, gather all those scraps and add them to the bag.
Continue to add to this bag until it’s full or until 6 months have passed from your penned date. After 6 months, it’s time to make your vegetable broth!
What Vegetables Can Be Used for Scrap Broth?
There is such a variety of delicious vegetables that can be added to make a flavorful broth. Whether it be their skins, peels, cores, ends, or just pieces of the vegetable that go unused in recipes, a variety of different vegetables makes for the tastiest broth.
Here are some vegetables that can definitely be added to your broth successfully:
- Onion and shallots
- Garlic
- Asparagus
- Mushrooms
- Celery
- Carrots
- Potatoes (including sweet potato)
- Herbs
- Tomatoes
- Bell peppers
- Squash
- Peas
- Green beans
- Zucchini
- Corn (including just the cobs)
- Shallots
- Leeks
- Leafy greens like kale spinach, arugula, spring mix, and/or watercress
- Cabbage
- Citrus peels (in moderation, and with something sweet like sweet potato skins or apple cores and peels to balance out)
- Apple cores and peels
What Veggies Should Not Be Used for Scrap Broth?
On the other hand, there are a few vegetables in particular that will bring a strong bitter taste to your broth, and should be avoided including:
- Broccoli
- Cauliflower
- Brussels sprouts
- Beets
- Turnips
- Radishes
How to Make Vegetable Scrap Broth
Add Enough Water to Cover Your Scraps
Since the amount of vegetable scraps that you save over a 6-month period may vary, I did not include an exact measurement for the amount of water you add to make this broth.
Instead, you will rely on a simple sight test to get the perfect amount of water.
Start by adding your veggie scraps to a large pot with the salt and garlic cloves. Then, start to pour water overtop, until all of the veggie scraps are completely submerged and some of the uppermost scraps start to float.
How Long to Boil Homemade Vegetable Broth from Scraps?
Bring your veggie scraps, water, salt, and garlic to a boil. Please note that it may take a little bit longer than normal since your vegetable are frozen.
Once boiling, bring it down to a simmer and cover. You can simmer the broth for up to an hour for deep flavor, but make sure to give it at least 30 minutes.
I find that 30 minutes covered is plenty of time to extract flavor from your vegetable scraps.
Double Strain Your Broth
Once you’ve boiled flavor into your broth, you’ll want to get all of the scraps out, so you’re left with just the liquid. Since it’s really hot, I find that the safest and most effective way to do so is in two steps. You’ll need a sieve.
Use the sieve to fish out scraps from the hot broth first. This will help you get most of the larger pieces out.
Then, give your broth some time to cool. The next part can sometimes be a little messier, and you definitely don’t want super-hot liquid splashing all over you and your kitchen.
Once you’re comfortable with the temperature of your broth, pour it through a sieve to sift out any smaller scraps that may be left behind.
These discarded scraps can easily be composted.
How to Use Veggie Broth
If you’ve made some of my recipes before, you may have noticed that vegetable broth is a staple in my cooking. It adds such depth of flavor to a wide range of different dishes.
I use it as a base to most of my soups, and often use it in place of water to make more flavorful grains like rice, quinoa, and farro.
Here are some of my favorite dishes that rely on vegetable broth for a boost of flavor:
- Creamy Cajun Salmon and Grits
- Aromatic Yellow Saffron Rice
- Mediterranean Quinoa Bowl
- Creamy Vegan Wild Rice Soup
- Pumpkin & Mushroom Risotto
- Everything Bagel Stuffing
- Savory Breakfast Quinoa Bowl
- Hearty Mushroom Gravy
Green tip: Making your own veggie broth not only makes the most out of your produce, but it also helps you avoid extra packaging waste that you will otherwise have to dispose of if you buy vegetable broth at the store.
How to Store Vegetable Scrap Broth
Once you’ve made your delicious vegetable broth from scraps, store it in a large glass container with a lid. I like to write the date on the lid so I can keep track of when I made it.
It will stay fresh in your airtight container in the refrigerator for up to 4 days. It can also be frozen for up to 3 months.
For an easy storage hack, you can add the broth to ice cube trays and set them in the freezer to form little broth cubes. Then, these can be transferred to a freezer bag, left in the freezer, and easily added to a pot to be melted down back into broth.

Vegetable Stock Vs Vegetable Broth
By definition, stock is made from bones. So, while you can’t technically make stock from just vegetables, you can definitely make broth from vegetable scraps.
Boil your vegetable scraps with salt, water, and fresh garlic and then reduce the heat, cover, and simmer for at least 30 minutes. Strain and you’re left with a delicious broth!
If Your Vegetable Broth Comes Out Bitter
If your vegetable broth is bitter, you have likely added some veggies or scraps from the “don’t” list. This includes broccoli, cauliflower, brussels sprouts, beets, turnips, and radishes.
Additionally, while I do encourage you to add citrus peels and piths to the broth, they should only be added if you are also adding something sweet like sweet potato peels and/or apple peels and cores to balance out the broth.
Vegetable Peelings in Vegetable Broth
Adding vegetable scraps to any stock will add tons of flavor—and not just peelings! Peels, stalks, cores, leaves, and leftovers all work for broths and stocks.

I was wondering if we can make this broth in an instant pot and how long would we cook it for?
Absolutely you can! Just 30 minutes should do the trick, and then strain it from there. Just make sure you don’t overfill the water past the max line, but otherwise- easy peasy! Enjoy!
