Roasted Vegetable Stock
This is the only vegetable stock recipe you need to know. I usually do not make blanket statements like this, but when it comes to vegetable stock, this one is the only one worth using. The technique used to pull out as much flavor from the vegetables is so genius and obvious, I often wish I thought of it myself. What makes this stock so wonderful and puts all other vegetable stock recipes to shame? The brilliant idea of roasting the vegetables before you simmer them in water.
This is Mark Bittman’s recipe for vegetable stock from, How to Cook Everything. In his cookbook, Mark Bittman writes about his technique of roasting the vegetables before simmering them in the stockpot as the one step he always does when making vegetable stock. He has the talent for paring down a recipe to include only the essential techniques to get the most amount of flavor. Yet, for making vegetable stock, he adds an extra step and it is essential. Because Mark Bittman is often so nonchalant about things, that when he says, “This is the one thing to do when making vegetable stock,” I do not question his wisdom. I follow.
Building Extra Flavor
Once you roast the vegetables then simmer them for stock, you will see how important this step is. When vegetables roast in the oven, their flavor concentrates and browning occurs. This browning adds extra body and flavor on top of the flavor you get from roasting. If Emeril Lagasse was making this recipe he would shout out, “Bam,” and with a flick of his wrist, like its a magic wand, present this vegetable stock masterpiece.
Honestly, there are two extra steps because you must deglaze the pan after roasting the vegetables then add all that extra flavor into the stock.
Another bonus with deglazing the pan is, it helps with the cleanup later on. All the baked on goodness, (I know you are looking at the photo and thinking clean-up is going to be a bitch) dissolves into the warm water as you scrape it off the bottom of the pan. Voila, half the clean up is done before you finish the stock.
Vegetables for Vegetable Stock
“Vegetable for Vegetable Stock” sounds like a political campaign slogan. Though I am not on a political crusade, I am on a homemade vegetable stock crusade. The essential vegetables for making stock are celery, carrots, onions, and leeks. Use the onion skins because they add great color to the stock. Feel free to use the whole plant, roots and all. Carrot tops and celery leaves I add later to the simmering stock with the herbs, But everything else roasts together in one roasting pan.
Other vegetables depend on what you are making and have on hand. What is important to keep in mind is, whatever vegetable you use will influence the flavor of the stock. If you use broccoli stems, the stock will taste like broccoli. If you use asparagus ends, the stock will taste like asparagus and have a khaki green glow. Sometimes bitter vegetables get more bitter when roasted or cooked. So, keep in mind what you are making with the vegetable stock and add extra vegetables to complement the meal. If you are making vegetable stock for broccoli soup, then broccoli stems are perfect in the stock. If you are making mushroom risotto, then using broccoli is not the best choice, but reconstituted mushrooms and fresh mushrooms are along with the essential vegetables.
For my vegetable stock I generally use, celery, carrots, onions, leeks, garlic cloves, parsnip, turnip, and mushrooms with fresh herbs. Sometimes I add fennel stalks, but not too many.
Potatoes are common vegetables in stock, but I have yet to use them. Instead of potatoes, I like to use parsnips and turnips. What concerns me about using potatoes is I do not want the stock to get cloudy and I believe the starches in potatoes will cause that to happen. Also, I do not want my stock to taste like potatoes.
Cutting Back on Food Waste and Make Stock
To cut back on food waste, I keep a stash of vegetable scraps in my freezer specifically to use in chicken and vegetable stock. It is great to save on food items you frequently cook with, like mushrooms stems and the dark green parts of cleaned leeks instead of throwing them away. Fennel scraps get thrown in there as well. Recently I froze a bunch of swiss chard stalks from my Savory Tart of Swiss Chard and Butternut Squash and used them in my vegetable stock. Whatever vegetable scraps I do not use I compost even though I do not have a vegetable garden. Composting your kitchen scraps help reduce the carbon emissions in the atmosphere.

For the first time, make the vegetable stock using the recommended vegetables and discover the vegetable flavor developed from the recipe. Once you get familiar with making stock, you can experiment with using different vegetables and come up with your own varieties.
Mark Bittman lists white wine as one of the ingredients in the stock. If I have a dry white wine like Sauvignon Blanc or Pinot Grigio on hand I use it. If not, I don’t. The wine does make the flavors brighter but is not so important that you need to make a special trip to the liquor store.
Discovering this vegetable stock recipe was a life changer for me. Up until then, store-bought vegetable stock tasted meh and the flavor unreliable. Any homemade version tasted just a step up from water. I like using vegetable stock in meals like risotto and vegetable stews because chicken stock sometimes is too strong a flavor. Sure, you can use chicken stock in all these foods, especially if you are not cooking for a person eating a plant-based diet, but it makes everything taste like chicken soup. As much as I love chicken soup, I do not want everything to taste like it. Having a good vegetable stock recipe is a necessity.

Roasted Vegetable Stock
You can use most vegetables for making stock, just keep in mind that the stock will taste like the vegetables you made it with. The essential vegetable stock ingredients are celery, onion, carrots, and leeks. Any additional vegetables are bonuses. I happen to love the flavor of parsnips and turnips in stocks and use them often. Parsnips have a distinct and sweet flavor, that I believe gives vegetable stock a unique flavor.
This recipe is from, How to Cook Everything By Mark Bittman.
Makes 3 quarts
- 2 washed leeks cut in half or 2 onions quartered with the peel intact.
- 3 carrots peeled and cut in half
- 3 celery stalks cut in half, add some celery leaves during the simmer
- 2 parsnips peeled and cut in half optional
- 2 white turnips peeled and quartered optional
- 2 potatoes peeled or well washed and quartered optional and use if you do not use parsnips or turnips
- 1 cup (250 ml) mushrooms or mushroom stems. Or ¼ cup (60 ml) reconstituted dried mushrooms with soaking liquid)
- 6 garlic cloves still in its papery skin or shallots
- 4 TBS extra virgin olive oil
- 3 bay leaves
- 10 sprigs parsley
- 2-3 sprigs fresh thyme
- 10 peppercorns
- ¼ cup 60 ml dry white wine
- Kosher salt to taste
- 2 quarts (2 liters) water, plus 4 cups (1 liter) of water for deglazing
Preheat the oven to 400°F (200°C). Place the vegetables on a rimmed baking sheet or large roasting pan. Do not add reconstituted mushrooms or fresh herbs at this time. Be careful not to overcrowd the pan. Use two sheet or roasting pans if necessary. Drizzle the vegetables with the extra virgin olive oil and Kosher salt. Toss the vegetables with your clean hands to evenly coat.
Roast the vegetables in the oven until they are browned and soft. Check the vegetables every twenty minutes and turn them around with a thin metal spatula. The vegetables should take around 45 minutes to finish roasting.
Remove the vegetables from the roasting pan and place all the ingredients in a large stockpot. Add the remaining vegetables, fresh herbs, bay leaves, peppercorns, wine, and 2 quarts of water. Turn on the heat to high.
Place the roasting pan over two burners and pour in the remaining water. Begin with 2 cups (500 ml) of water as it is easier to pour back into the stock pot from the roasting pan. Turn the heat to high and bring the water to a boil. Use a wooden spoon and scrape off the browned bits on the bottom and sides of the pan. Pour the liquid into the stockpot with the vegetables and add remaining water. It is awkward handling a large sheet pan or roasting pan filled with water, so be careful.
Bring the stock to a just about a boil, turn down the heat and cover the pot with a lid part way. Maintain the temperature at a low simmer. You should see a few bubbles reaching the surface at a time. Cook until the vegetables are very soft and tender. This can take from 30 -45 minutes. Taste.
Place a colander over a large bowl big enough to hold 3 quarts. Pour out the vegetables into the colander and drain the stock in the bowl. Press down on the vegetables to extract as much stock as possible without pressing in any solids into the stock. Taste and adjust for salt if needed.
Refrigerate and chill for a couple of hours then skim off any hardened fat floating on the surface if you like. Store in the refrigerator for 4-5 days or freeze for a couple of months.
