Ingredients You’ll Need

- 2 medium red onions, thinly sliced: Provides the crisp, slightly sweet foundation with a punch of color.
- A few good pinches of kosher salt: Essential for “washing” the onions to mellow their sharpness and create a tender texture.
- ¼ cup neutral oil: Such as vegetable oil or extra virgin olive oil; adds richness and helps meld the flavors.
- ¼ cup fresh lime juice: The zesty citrus brightens the dressing and adds necessary acidity.
- 2 tablespoons red wine vinegar: Adds depth and enhances the tangy profile.
- ½ teaspoon aji amarillo paste (optional): Brings authentic Peruvian heat and a subtle fruity kick.

How to Make Salsa Criolla (Red Onion Dressing) Recipe
Step 1: Prep and “Wash” the Onions
Start by thinly slicing the red onions from top to root to retain their crisp texture. Then, place the slices in a bowl, sprinkle with kosher salt, and cover with cold water. Gently squeeze the onions in the water—this crucial step helps separate the membranes, softening their bite and making them taste sweeter. Drain and repeat with fresh cold water, squeezing again but without adding more salt to finish mellowing their sharpness.
Step 2: Combine Ingredients
Once the onions are well rinsed and drained, it’s time to add in the remaining ingredients: neutral oil, fresh lime juice, red wine vinegar, aji amarillo paste (if you’re using it), kosher salt, and pepper. Stir everything together gently but thoroughly to ensure all flavors marry beautifully.
Step 3: Adjust Seasoning and Garnish
Taste your dressing and tweak the salt and pepper to your preference. Finally, sprinkle freshly chopped cilantro on top for that burst of color and herbal freshness that makes the Salsa Criolla (Red Onion Dressing) Recipe truly sing.

This dressing shines as a vibrant garnish. Try topping your grilled beef, chicken, or pork with a generous spoonful right before serving to add a refreshing crunch and lively acidity that cuts through rich flavors.
Side Dishes
Salsa Criolla also pairs beautifully alongside seafood dishes or with simple sides like black beans or roasted vegetables. Its bright acidity and slight heat make it the perfect foil for hearty, comforting flavors.

This versatility means your Salsa Criolla (Red Onion Dressing) Recipe can become a staple condiment for countless dishes, allowing you to get creative in the kitchen while enhancing flavor and texture.
Make Ahead and Storage
Storing Leftovers
You can keep any leftover Salsa Criolla stored in an airtight container in the refrigerator for up to three days. The flavors will continue to meld, making it even tastier after a day or two.
Freezing
Freezing this dressing is not recommended. Since it relies heavily on fresh onions and citrus juice, freezing can alter the texture and diminish the bright, crisp qualities that make the Salsa Criolla (Red Onion Dressing) Recipe so delightful.
Reheating
Because Salsa Criolla is best served fresh and chilled, reheating is unnecessary and not advisable. Instead, simply give it a stir and enjoy straight from the fridge for maximum freshness and zing.
FAQs
What does “washing” the onions mean and why is it important?
Washing the onions involves soaking and gently squeezing them in salted water to remove some of the harsh sulfur compounds. This process softens the bite, making the onions milder and slightly sweeter, which is essential for a balanced Salsa Criolla.
Can I substitute the aji amarillo paste?
Absolutely! If you don’t have aji amarillo, you can use a mild chili paste or fresh jalapeño to add some heat, but keep it light to maintain the authentic flavor balance of the Salsa Criolla (Red Onion Dressing) Recipe.
Is this dressing spicy?
The spice level depends on your use of aji amarillo paste. If you leave it out, the Salsa Criolla will be bright, tangy, and mild. Adding aji amarillo introduces a gentle, fruity heat that complements the acidity perfectly.
How thin should the onion slices be?
Thin slices work best—about 1 to 2 millimeters thick. Thinly slicing the onions ensures they soften during the washing process and absorb the dressing flavors seamlessly without dominating the dish.
Can I prepare this dressing in advance?
Yes, you can prepare Salsa Criolla ahead of time. Refrigerate it for a few hours or overnight for the flavors to deepen. Just be sure to enjoy it within three days to savor its fresh taste.
