Ingredients Overview for Onion Salad

The ingredients for this Onion Salad come together in a harmonious blend of flavors that complement each other beautifully. The key players are the onions, which provide that signature crunch, and the sweet and tangy dressing made from sugar, vinegar, and mayonnaise. Each ingredient plays a crucial role, allowing the salad to shine.
- 4 large white or yellow onions: Sliced into rounds and separated, these onions serve as the salad base, providing a crunchy texture and sharp flavor.
- 1/2 cup granulated white sugar: This adds sweetness that balances the sharpness of the onions.
- 1/4 cup cold water: Used to dissolve the sugar and create a syrupy base for the salad.
- 1/4 cup white vinegar: Adds acidity and tanginess to the dish, enhancing the overall flavor profile.
- 1/2 cup real mayonnaise: This creamy component brings everything together, giving the salad a luscious texture.

How to Cook Onion Salad

Preparing the Onion Salad is a simple and rewarding process. With just a few steps, you can create a dish that’s not only delicious but also visually appealing. Let’s dive into the cooking method!
- Begin by slicing the raw onions into 1/8-inch rounds. Make sure to separate the layers by hand to ensure an even texture throughout the salad. As you slice, you’ll notice the sweet aroma of the onions filling the air. This is the first indication that you’re on the right track. Place the sliced onions into a large mixing bowl and set it aside for now.
- In a separate small bowl, combine the sugar, water, and vinegar. Stir the mixture until the sugar is fully dissolved, which should take just a couple of minutes. This sweet-and-sour dressing is the magic that will transform the onions into something special.
- Pour this sweet mixture over the sliced onions in the mixing bowl. Use a spoon to gently stir, ensuring that each slice is well-coated with the dressing. This step is crucial, as you want every single layer of the onions to soak in the flavors.
- Cover the bowl with plastic wrap and refrigerate for about three hours. During this time, stir the salad every hour to ensure that all parts of the onions are exposed to the sugar water. This marinating process helps to reduce the bite of the onions, making them sweeter and more palatable.
- After marinating, carefully drain the liquid from the onions. This step is essential to avoid a watery salad. Take a moment to dry the onions off with a paper towel to remove any excess moisture that could dilute the flavors.
- In a clean bowl, mix the mayonnaise and poppy seeds together. This creamy dressing will add richness to the salad. Stir until fully combined. The poppy seeds will add a delightful crunch and a touch of visual flair.
- Now, gently fold the creamy mixture into the marinated onions. Use tongs here if you need help; they can help you evenly coat the onions without breaking them apart. This is where the magic happens, as everything comes together into a luscious salad.
- After mixing, return the salad to the refrigerator for at least another hour. This additional chilling time allows the flavors to meld even further, giving you a more harmonious dish.
- When you’re finally ready to serve, season the salad with salt and pepper to taste. This final touch is important to elevate the flavors, bringing out the best in the Onion Salad.
- Serve cold, preferably with tongs to keep everything intact. Enjoy the crunchy, creamy, and flavorful experience of this delightful dish!
Things Worth Knowing
- Choose Quality Onions: Opt for fresh, firm onions for the best flavor and texture. Avoid onions with soft spots or blemishes.
- Marinating Time is Key: Don’t rush the marinating process! The longer the onions sit in the dressing, the more the flavors develop.
- Adjust Sweetness: Feel free to adjust the amount of sugar based on your taste preference. Some might like it sweeter than others.
- Experiment with Vinegar: Try different types of vinegar like apple cider or rice vinegar for unique flavor profiles.
- Serving Temperature: This salad is best served chilled, as it enhances the refreshing qualities of the dish.
