With just a few minutes of hands-on time and five simple ingredients, this method is a favorite for cooking onions.

As an onion and sous vide fan, I asked the obvious question: can you sous vide onions? The answer is yes. Marinating sliced onions in beer before finishing them in a sous vide bath yields tender, melt-in-your-mouth results that concentrate sweetness and beer flavor without overpowering the dish.

Ingredients for sous vide onions in beer
This recipe uses six straightforward ingredients: olive oil, garlic, yellow onions, salt, pepper, and beer (or broth). Slice the onions thin—about 1/2-inch slices—so they cook evenly and soften during the quick stovetop step and the sous vide bath.

How to make sous vide onions in beer
Step 1. Start with a short stovetop sauté. Heat 1 tablespoon olive oil in a pan over medium heat. Add sliced onions, 2 minced garlic cloves, salt and pepper, and stir for about 5 minutes until the onions begin to soften.

Step 2. Pour in 1 cup beer (lager works well) or substitute chicken/vegetable broth if you prefer. Reduce the heat to medium-low and cook for another 5 minutes, stirring occasionally, until the onions become translucent and the beer reduces slightly.

Step 3. Transfer the onion mixture into a vacuum-seal bag and arrange the contents in an even 1-inch layer so they cook uniformly. Seal the bag, taking care to avoid losing liquid during sealing. Sous vide at 185°F (85°C) for 2 hours.

Step 4. When the sous vide cycle is complete, pour the contents into a pan over medium heat to reduce any remaining liquid and concentrate flavor. Serve the onions hot as a topping or chilled as a make-ahead condiment.

What to pair with your sous vide onions in beer

FAQs
What size onions should I use?
Sliced yellow onions work best for this recipe. If using pearl onions, halve them or leave very small ones whole. I don’t recommend attempting whole large onions with this specific method.
Does the entire bag need to be submerged in water?
Yes — for even cooking, make sure the bag is fully submerged. When sealing a bag containing liquid, let it hang off the counter edge so gravity pulls liquid down away from the seal area. If your vacuum sealer struggles, consult its guidance for sealing liquids.
What if I don’t want to use beer?
Chicken or vegetable broth are excellent substitutes if you prefer no alcohol or a milder flavor. Broth yields a similar depth without the beer notes.

Recipe Notes & Tasty Tips
- Pre-sliced sous vide onions are fantastic on tacos, pulled pork, and sausage sandwiches.
- If sealing bags with liquid proves difficult, let the bag hang during vacuuming so liquid settles away from the seal line.
- After sous vide, a few minutes in a pan helps evaporate excess liquid and intensify flavor.
- Swap beer for vegetable or chicken broth whenever desired.
The Perfect Sous Vide Setup
Use a reliable sous vide device and a suitable container for consistent temperature control. Proper sealing and arranging the bag in a thin, even layer help ensure all onions reach the same texture.
