The backstory.

One afternoon, I had a sudden, unstoppable craving for a big pot of cozy vegetable soup. I started chopping veggies, only to realize I was completely out of broth — not even a cube or carton in sight!

Instead of scrapping the plan, I decided to make vegetable stock with simple ingredients I already had. It simmered away while I prepped the rest of the soup, and honestly, the fresh, rich flavor was a total game-changer. Now I always keep some on hand — because you never know when a soup craving will strike!

It's a must-make.

This homemade vegetable broth is fabulous and here's why:

  • Incredibly easy - just toss everything into a pot over medium heat and simmer away!
  • Amazing depth of flavor - roasted vegetables, garlic, herbs, and olive oil build a bold, cozy flavor without any added junk.
  • Zero waste - put leftover veggie scraps, onion skins, or even dried mushrooms to use. All will add a deeper flavor.
  • Flexible and freezer-friendly - make a big batch, then stash in the freezer for soups, grains, or sauces later on!
  • Homemade is healthier - skip the added sodium and preservatives often found in boxed stock or canned veggie broth.

When a soup craving strikes, homemade broth saves the day — and tastes a hundred times better, too!

Let’s talk texture and flavor.

This broth is anything but bland. It’s savory and herbaceous, with gentle sweetness from carrots and onion, a mellow richness from garlic and olive oil, and a warm, earthy finish from peppercorns and thyme. Every sip of this vegetable broth has a round, comforting depth you just don’t get from boxed veggie broth.

What you'll need.

Ingredients needed for making a classic vegetable stock.

You’ll be amazed how easy it is to make a high-quality basic vegetable stock from ingredients you probably already have:

  • Olive oil: used to saute and sweat the vegetables
  • Garlic: a classic, delicious flavor that complements so well.
  • Water: cold water is best to draw out all the slow-simmered goodness from your veggies.
  • Vegetables: onions, carrots, and celery, the base aromatics for the perfect stock.
  • Seasonings: black peppercorns and kosher salt, adjust as desired.
  • Herbs: fresh thyme and bay leaves.

Looking for other stock options? Whether you're after the rich depth of beef stock, the savory comfort of chicken stock, or the bold flavor of lamb stock, I have easy, no-fuss recipes for each one. They follow the same simple, approachable method as this vegetable stock—just with a few flavorful twists. Check them out to stock your freezer with delicious options for any meal!

Customize it your way.

One of the best things about this vegetable stock recipe is how customizable it is. Try adding:

  • Tomato paste for extra richness and depth.
  • Dried mushrooms for a deep umami flavor.
  • Fennel or leeks for a pop of freshness.
  • Roasted vegetables to intensify the savoriness.
  • Veggie scraps like celery tops, carrot peels, and onion skins can be used to reduce food waste and maximize flavor.
  • Add fresh veggies like corn cobs or bell peppers for a bit of sweetness.
  • Fresh parsley or other fresh herbs for flavor or garnish.

Flexible dietary swaps.

Here are some healthy alternatives for this flavorful broth:

  • High Protein Add-in: Stir in miso paste or finish your soup with protein-rich beans or lentils when using the broth.
  • Oil-Free: Skip the olive oil and dry-sweat your vegetables with a splash of water or stock.
  • Low FODMAP: Use green tops of scallions instead of onion, skip garlic, and add fennel or parsley stems.

Ingredients
  

  • 1 tablespoon olive oil
  • 24 ounces onion (large dice)
  • 16 ounces carrots (large dice, no need to peel just clean well)
  • 16 ounces celery (large dice)
  • 2 bay leaves
  • 6 quarts water
  • 10 black peppercorns
  • 3 cloves garlic
  • 3 sprigs fresh thyme
  • Optional: kosher salt to taste

Instructions
 

  • Heat olive oil in a large stock pot over medium heat. Add onions, carrots, celery, and the bay leaf. Cover, stirring often, and sweat until the vegetables soften slightly and become aromatic, about 5 minutes. (Tip: Sweating vegetables means gently cooking them without letting them brown. Keeping the lid on traps moisture, helping them soften and release their natural flavors.)
  • Add the water to the pot and bring to a boil. Reduce heat to low and simmer gently.
  • Add spices and herbs and contnue cooking for approximately 1 hour.Stir in the peppercorns, garlic, and thyme. Continue simmering, uncovered, for about 1 hour.
  • Place a fine-mesh sieve over a large bowl or another pot. Pour the broth through the sieve, discarding the solids.
  • Season to taste with kosher salt if desired. Cool quickly by setting the bowl of broth into an ice bath, then refrigerate or freeze as needed.
