HOW TO MAKE Pickled Red Onions
Making pickled red onions is fast and hands-off. You only need a few tools and fresh limes. The acid from lime juice and a splash of cider vinegar cures the onions and gives them their pink color. Use a glass jar to store them and mix them well so all slices soak in the juice.
If you enjoy strong contrasts of sweet and tart, try pairing pickled onions with a cozy drink such as the cozy red velvet latte after a bright meal. The acid in the onions cuts richness and helps the whole plate feel balanced.
EQUIPMENT NEEDED
- Sharp chef’s knife or mandoline for thin slices
- Glass bowl or glass jar with lid (for picking)
- Lime squeezer or citrus press
- Measuring spoons
- Stirring spoon or tongs
Ingredients You’ll Need :
1 red onion, peeled and thinly sliced, 4 limes, juiced, 1 tablespoon cider vinegar, 1 teaspoon kosher salt, 1/2 teaspoon fresh ground pepper
STEP-BY-STEP INSTRUCTIONS :
Slice the onions thinly with a sharp chef’s knife or a mandoline. In a large glass bowl or jar, add all ingredients and toss to combine, making sure the onions are coated through. Refrigerate for at least 30 minutes before serving, shaking or mixing the onions at least once while they cure. Taste before serving and add salt if needed. Make sure to use a glass container. Use a lime squeezer to get the most juice from the limes. Ensure enough lime juice covers the sliced onions. The onions will turn a deep pink color the longer they are cured. For best taste, consume within 1 week, stored in a glass container in the refrigerator.
HOW TO SERVE Pickled Red Onions
Serve these onions in small portions to add a burst of flavor. One to two tablespoons per serving is a good portion. For salads, use 1–2 tablespoons per bowl. For tacos or sandwiches, top each taco or sandwich with 1–3 tablespoons. They are low calorie and low carb, so they help you add big taste while keeping a dish light.
They are an easy way to bring fresh flavor to a high protein meal. Add them to grilled chicken, baked fish, or tofu to make a simple protein plate into a bright and balanced dish. They also work well on top of grain bowls, with beans, or in wraps.
If you want a drink to match, a tart pickled onion can go with a sweet or creamy beverage. For a fun contrast after dinner, serve a small cup with an iced treat such as the iced latte inspired by Beetlejuice. The acid in the onions pairs well with sweet drinks and helps reset the palate.
STORAGE & FREEZING : Pickled Red Onions
Store pickled red onions in a clean glass jar with a tight lid. Keep them in the refrigerator. They stay fresh for up to 1 week for best taste and texture. The longer they sit, the softer they become and the color gets deeper.
Do not freeze pickled red onions. Freezing breaks their crunch and changes their texture. If you need to keep them longer, make smaller batches and use within the week. Always use a clean spoon to remove onions to avoid contamination and extend shelf life.
SERVING SUGGESTIONS
- Pair with a grilled chicken breast for a balanced, high protein meal.
- Top a mixed green salad with 1–2 tablespoons for added flavor and fiber.
- Add to avocado toast with a squeeze of lime for a lighter option at breakfast.
- Use on tacos with lean fish, shrimp, or turkey for low calorie flair.
- Mix into a bean salad for texture and tang without extra carbs.
A healthy serving plate can be one palm-sized portion of protein, a fist of vegetables, and 1–2 tablespoons of pickled onions for flavor. This keeps calories low and lets the protein shine, making it a good choice for weight loss plans.
VARIATIONS
- Healthier version: Use extra lime juice and skip the cider vinegar if you prefer a purer citrus taste. Reduce salt to 1/2 teaspoon and use a pinch of sweetener only if you need it. This keeps the jar low sodium and low sugar for a lighter option.
- High-protein / low-carb version: Serve the onions with a high protein meal such as grilled salmon, chicken, or a tofu steak. You can also add pickled onions to a bowl of roasted Brussels sprouts and tempeh for a high protein, low carb plate. The onions add flavor while keeping carbs low.
- Air fryer or oven-baked version: For a warm, quick-pickle twist, roast sliced red onions in the air fryer or oven first. Toss onion slices with a small amount of oil and roast at 400°F (200°C) for 8–12 minutes until slightly charred. Let cool, then add lime juice, cider vinegar, salt, and pepper and let them sit in the fridge for 30 minutes. This gives a smoky, tender pickled onion that works well on roasted meats and grain bowls.
Other ideas: add thin herbs like cilantro or thyme, or add a sliced jalapeño for heat.
