Onion juice is easier to cook with than it looks. Here's how to choose, use, and store it, what to substitute, and 17 recipes to get you started.

What is onion juice?

Onion juice is the liquid pressed from fresh onions, with the pulp and fiber left behind. It carries the bulb's full pungent flavor in a form you can stir into anything without adding a single visible piece of onion.

That is the whole point. When you want onion taste but not the texture, the juice does the job: smooth dressings, marinades, dips, and tender meatballs all benefit from it.

You can make it at home by grating an onion and squeezing the pulp through cheesecloth, or by buzzing chunks in a blender and straining. A medium onion yields only a few tablespoons, so a little is precious.

How to Use Onion Juice

Use it anywhere a clean onion flavor matters and bits of onion would distract. It blends without a trace into creamy and pourable mixtures, which is why it turns up in salad dressings like this Paprika Salad Dressing and in a smooth Contemplating Cape Cod Clam Dip.

In marinades it does double duty. The flavor seasons the surface while the onion's natural enzymes gently tenderize meat and poultry, as in this Deep-Fried Wild Turkey.

It is raw and sharp, so add it to taste near the end. A teaspoon or two flavors a whole batch of dressing; pour with a heavy hand and the dish turns harsh and bitter.

Pairing and What Goes Wrong

Onion juice plays well with vinegar, mustard, mayonnaise, lemon, and warm spices, so it slots naturally into vinaigrettes and seafood dips. It also cuts the sweetness in barbecue sauces, like this Pit Barbeque Sauce.

The common mistake is treating it as mild because it is liquid. It is concentrated raw onion, more assertive than you expect. Start small, and never use it where you really wanted the sweet, cooked depth of sauteed onions, which juice cannot give.

Substitutes

In a pinch, grate fresh onion and use both the pulp and juice, or strain out the solids if texture is the issue. A small amount of onion powder dissolved in water approximates the flavor without the bite.

For a milder result, the juice from grated shallot works. None of these match the fresh, sharp lift of true onion juice, but each gets you close in a dressing or marinade.

Buying and Storing

Bottled onion juice is uncommon on shelves, so most cooks make it fresh as needed. That is the better path anyway, since the flavor is brightest right after pressing.

Fresh onion juice fades and turns sulfurous fast. Keep it covered in the refrigerator and use it within a day or two; do not leave it at room temperature, where it sours quickly.

You can freeze it in an ice cube tray for longer storage, then drop a cube into a sauce or marinade as needed.
