Sous Vide Caramelized Onions for Burgers and Steaks

Caramelized onions are a delicious addition to burgers and steaks, adding a sweet, savory flavor that elevates any dish. Traditionally, caramelizing onions requires slow cooking on the stovetop, which can be time-consuming. However, using a sous vide method simplifies the process and guarantees perfectly caramelized onions every time.

Why Use Sous Vide for Caramelized Onions?

The sous vide technique involves cooking food in a sealed bag submerged in a water bath at a precise temperature. This method ensures evenly cooked onions that develop deep, rich flavors without the risk of burning. It also allows you to prepare onions ahead of time, making meal prep more convenient.

Ingredients Needed

• 2 large onions, thinly sliced
• 2 tablespoons olive oil or butter
• 1 teaspoon salt
• Optional: 1 teaspoon sugar for extra sweetness
• Fresh thyme or rosemary (optional)

Step-by-Step Instructions

1. Prepare the onions: Slice the onions thinly and place them in a vacuum-sealable bag. Add the olive oil or butter, salt, and optional sugar and herbs.

2. Seal the bag: Remove excess air using a vacuum sealer or the water displacement method if using a zip-top bag.

3. Set up the sous vide: Preheat your water bath to 85°C (185°F). Submerge the sealed bag in the water, ensuring it is fully submerged and not floating.

4. Cook the onions: Let them cook for 1.5 to 2 hours. The slow, gentle heat will develop their natural sweetness and create a rich caramelized flavor.

Finishing Touches

After cooking, open the bag and transfer the onions to a skillet if you want to add a bit of color or extra caramelization. Sauté for 2-3 minutes over medium heat until slightly browned. These onions are perfect for topping burgers, steaks, or even adding to sandwiches and salads.
