What do you do with your onion peels, carrot ends, and celery tops? Before you toss them straight into the compost bin, what if you could get one more incredible, flavorful use out of them?
Welcome to one of the wisest and most satisfying frugal kitchen hacks: making homemade vegetable broth from scraps.
This simple process turns what most people consider “trash” into a rich, golden, and deeply flavorful liquid. It’s practically free, tastes worlds better than the powdery cubes or a watery, salty carton, and it’s the truest definition of zero-waste, “root-to-stem” cooking.
Why You’ll Never Go Back to Store-Bought
- Completely Frugal: You are literally making something delicious from nothing. It’s free flavor!
- 100% Zero-Waste: This is the perfect step before composting. You’re extracting every last bit of flavor and nutrition from your scraps.
- Healthier & All-Natural: You control everything. No added salt, no MSG, no preservatives, no unpronounceable ingredients.
- Way More Flavorful: The taste is deeper, more complex, and more “real” than anything you can buy in a box.
The “How-To”: What to Save vs. What to Avoid
The secret to a delicious broth (and not a bitter, funky one) is knowing what to save.
Your best friend here is a large freezer bag or container. Label it “Broth Scraps” and keep it in your freezer. As you cook throughout the week, just add your clean scraps to the bag.
✅ The “YES” List (Save These!)
- The Aromatic Foundation: Onion peels (yellow and red add amazing color!), carrot peels and ends, celery ends and leaves. These are your flavor base.
- Aromatic Stems: Parsley stems, coriander (kuzbara) stems, dill stems.
- Savory Bits: Garlic skins and ends, leek greens (the tough dark green parts), mushroom stems (adds amazing umami!).
- Extras: Bell pepper ends (any color), corn cobs (after cutting off the kernels), herb sprigs (thyme, rosemary).
❌ The “NO” List (Compost These Directly!)
This part is crucial! Adding these scraps can make your broth bitter, cloudy, or just plain weird.
- Vegetables from the Cabbage Family: Broccoli, cauliflower, cabbage, kale, Brussels sprouts. They will make your broth taste and smell… unpleasant.
- Starchy Vegetables: Potato peels (they’ll make the broth cloudy and gummy).
- Bitter or Strong Flavors: Turnip, artichoke leaves, or too many hot pepper seeds.
- Anything Rotten or Dirty: Only use clean scraps. A little dirt can make the whole batch gritty.
Simple, Frugal Scrap Broth: The Method
Once your freezer bag is full (it usually takes me a week or two), you’re ready to make magic.
Ingredients:
- 1 large freezer bag (about 4-6 cups) of frozen vegetable scraps
- Water (enough to cover the scraps)
- Optional Add-ins: 1-2 bay leaves, a teaspoon of whole peppercorns, a few dried herbs.
Instructions:
- No Thawing Needed: Dump your entire frozen bag of scraps directly into a large soup pot (a halla).
- Cover with Water: Pour in just enough cold water to cover the scraps by about an inch or two (about 2-3 liters). Don’t add too much water, or your broth will be weak.
- Add Aromatics: Add your optional bay leaves and peppercorns. Do not add salt! You will season the broth later, depending on the recipe you use it for.
- Simmer, Don’t Boil: Bring the pot to a boil, then immediately reduce the heat to a low simmer. Let it simmer gently, partially covered, for about 1 hour. WiseHomist Tip: Unlike meat broth, you don’t want to simmer vegetable broth for hours. After an hour, the scraps have given all their flavor, and they can start to turn bitter.
- Strain: Pour the broth through a fine-mesh sieve or colander into a large bowl. You can gently press on the scraps to get all the liquid out.
- Cool & Store: Let the broth cool to room temperature before storing.
How to Use & Store Your Golden Broth
- In the Fridge: Store in airtight jars for up to 1 week.
- In the Freezer: This is the best method. Pour into freezer-safe containers, Mason jars (leave space at the top for expansion!), or even silicone ice cube trays.
- Frozen broth cubes are perfect for when you just need a splash to deglaze a pan or add flavor to rice. It lasts for at least 6 months.
