Pickled Onions Ingredients • Here’s everything you need to get started on these vibrant pickled onions! For the Pickling Mixture Red Onions – The star of this recipe; smaller onions are sweeter and ideal for pickling. White Vinegar – Provides a punch of acidity; swap for apple cider vinegar for a milder taste. Water – Acts as a diluting agent for the brine; there’s no substitute needed here. Cane Sugar – Balances the vinegar’s sharpness with sweetness; can be replaced with granulated sugar or honey. Sea Salt – Enhances flavor and helps preserve the onions; kosher salt is the best option. Optional Ingredients Garlic Cloves – Infuses extra savory goodness; feel free to skip if you prefer a simpler flavor. Mixed Peppercorns – Adds complexity and warmth; any whole spices can be substituted based on your taste. Curious how these pickled onions will transform your meals? Let’s get cooking! Step‑by‑Step Instructions for Gordon Ramsay’s Quick Pickled Onions Step 1: Prepare the Onions Start by peeling your red onions and slicing them as thinly as possible, aiming for uniform rounds using a sharp knife or mandoline for precision. This will ensure they pickle evenly and absorb the flavors beautifully. Aim for about 1/8-inch thickness for the best crunch. Step 2: Fill the Jars Divide the sliced onions among 2 or 3 clean glass jars, packing them tightly but not smashing them down. If you’re using optional ingredients like garlic cloves or mixed peppercorns, layer them in between the onion slices for added depth of flavor, ensuring an even distribution for optimal taste in your pickled onions. Step 3: Make the Brine In a medium saucepan, combine equal parts of white vinegar and water, along with cane sugar and sea salt. Heat this mixture over medium heat until it comes to a gentle simmer, stirring occasionally to ensure the sugar and salt dissolve completely. This usually takes about 5 minutes, and you should see small bubbles forming. Step 4: Cool the Brine Once the sugar and salt are fully dissolved, remove the saucepan from heat and allow the brine to cool slightly for about 5–10 minutes. This step is crucial; pouring very hot brine over the onions can soften them too much. The goal is to keep them crisp and vibrant for your delicious pickled onions. Step 5: Pour the Brine Carefully pour the slightly cooled brine over the packed onion slices in the jars, making sure they are fully submerged. You can use a spoon to push down any onions that float above the brine line. This ensures an even pickling process, allowing each slice to soak up all the tangy goodness. Step 6: Cool and Seal Let the jars of pickled onions cool to room temperature without lids for about 30 minutes. This helps prevent steam buildup that could alter their texture. Once cooled, seal the jars tightly with their lids and place them in the refrigerator. They will be ready after at least 1 hour but improve in flavor if left overnight. Step 7: Serve and Enjoy When you’re ready to brighten up your meal, grab those flavorful pickled onions! Add them to tacos, burgers, or salads for a tangy crunch that elevates every dish. These quick pickled onions can be stored in the fridge for up to a month, making them a perfect prepare-ahead option for your home meals! Make Ahead Options These Gordon Ramsay quick pickled onions are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the onions and brine up to 3 days in advance—simply follow the recipe up until you pour the brine over the onions, then refrigerate the jars. This allows the flavors to infuse beautifully. To maintain their crisp texture, ensure the brine is only slightly cooled before pouring it over the onions, and be sure they are fully submerged. When ready to serve, they’ll need at least 1 hour to soak for quick pickles, but overnight in the refrigerator is ideal for maximum flavor. Enjoy the convenience of having these tangy delights ready to elevate any meal!
