Serves: 12
Difficulty: Easy

Ingredients

2 large onions
3 carrots
3 celery stalks
2 tbsp neutral oil
12 cups cold water
2 bay leaves
1 handful parsley stems
6-8 black peppercorns
1 tsp salt

Step by step

Gather your vegetables. You need onions, carrots, and celery — the holy trinity. Two large onions quartered, three carrots chopped roughly, three celery stalks with leaves. Add any vegetable scraps you've saved: herb stems, mushroom stems, leek greens, tomato ends.
Heat oil in a large pot. Use a heavy-bottomed pot that holds at least 6 quarts. Add 2 tablespoons of neutral oil and heat over medium. You want the oil shimmering, not smoking.
Sauté the aromatics. Add onions, carrots, and celery. Cook for 8-10 minutes, stirring occasionally. The onions should be translucent and everything should smell sweet. This step builds the foundation of flavor.
Add water and seasonings. Pour in 12 cups of cold water. Add 2 bay leaves, a handful of parsley stems, 6-8 black peppercorns, and 1 teaspoon of salt. Bring to a boil over high heat.
Reduce and simmer. Once boiling, reduce heat to low. The surface should barely bubble — think lazy simmering, not aggressive boiling. Partially cover the pot and let it go for 45 minutes to 1 hour.
Strain the broth. Pour everything through a fine-mesh strainer into another pot or large bowl. Press the solids gently with the back of a ladle to extract more liquid, but don't mash them. Discard all the vegetables.
Cool and store. Let the broth cool to room temperature if storing. It keeps in the refrigerator for 5 days or freezer for 3 months. Pour into ice cube trays for easy portioning.

Tips & troubleshooting

Save vegetable scraps in a bag in your freezer — onion skins, herb stems, mushroom pieces all add flavor
Don't add cruciferous vegetables like cabbage or broccoli — they make the broth bitter and sulfurous
Taste and adjust salt at the end, not during cooking — the broth concentrates as it simmers
A splash of white wine added with the water deepens the flavor without making it boozy
If your broth tastes flat, add a squeeze of lemon juice just before using — acid brightens everything

Variations

Mushroom Broth. Add 2 ounces of dried mushrooms (porcini or shiitake work well) in step 4. The earthiness makes this perfect for risottos and grain dishes.
Roasted Vegetable Broth. Roast all vegetables at 400°F for 30 minutes before adding to the pot. This adds deeper, caramelized flavors and darker color.
Asian-Style Broth. Add ginger, green onions, and a piece of kombu seaweed. Skip the bay leaves and use white peppercorns instead of black.
Herb-Forward Broth. Double the fresh herbs — add thyme stems, oregano, and a few sage leaves. Perfect when you want the broth to be more than just background flavor.

Questions

How long does homemade vegetable broth last?: Five days in the refrigerator, three months in the freezer. Always cool it completely before storing, and reheat only what you plan to use.
Can I use vegetable broth instead of chicken broth in recipes?: Yes, but vegetable broth is lighter in body and flavor. You might need to reduce other liquids slightly or add more seasonings to compensate for the missing richness.
Why is my vegetable broth cloudy?: You boiled it too hard instead of simmering gently. Aggressive boiling breaks down the vegetables and creates cloudiness. The broth still tastes fine, just looks different.
What vegetables should I avoid in vegetable broth?: Skip anything from the cabbage family, beets (they turn everything pink), and starchy vegetables like potatoes. These either add off-flavors or make the broth cloudy and thick.
Can I make vegetable broth in a slow cooker?: Yes, use the low setting for 6-8 hours. The longer, gentler cooking extracts even more flavor from the vegetables. Strain the same way when finished.
