Peruvian Style Salsa Criolla

What’s better than crunchy red onions that are marinated in lime juice and give an amazing flavor punch to lots of meals? Salsa Criolla can be added to steak, fish, chicken, and potatoes. Just yesterday, I added them to some Greek style pulled pork that I served over rice. I’ve even put them on roasted turkey sandwiches for an added crunchy zing. Get creative!

brown wooden bowl filled with thinly sliced marinated red onions I also think these marinated onions are a great excuse to eat more tacos. But do we really need an excuse?

Traditionally in Peru, this is made with ají amarillo peppers. You could substitute jalapeño peppers or red, orange, or yellow bell peppers if you want. Or, just be a freakin rebel like me and leave the peppers out. This recipe is a milder version. And it’s damn delicious. Think of it as beginner’s salsa criolla.

Since I haven’t found fresh aji peppers in my area, I can’t speak on the flavor I’m missing. But I just know that the way I make them tastes so good, they don’t stand a chance of lasting in our fridge. We gobble them up.

What is salsa criolla exactly?

Salsa Criolla is a marinated onion relish that is found in Latin American cuisine. There are many variations that can include a number of ingredients such as onions, tomatoes, bell peppers, parsley, cilantro, vinegar, and oil. But the salsa doesn’t have to contain all those ingredients. Some recipes suggest soaking the onions in water, which tones down the onion flavor, producing a sweeter onion.

It is usually served with meat, but it’s also great with potatoes. Going to a picnic with various lunch meats? Bring these! That steak you’re grilling outside? It needs these tangy, crunchy onions.

There are no rules.

In Peru, it is served cold or at room temperature as a condiment.

How do you make it?

It’s so easy!

Cut a red onion in half and thinly slice.

You really want to get the onions as thin as possible. I like to cut them so thin, that they’re transparent.

hand holding sliced red onions to show how thinly to slice them for salsa criolla See how you can sort of see through them?

Please pretend you don’t see my dry, cracked, 104 year old hands. When I realized how bad they looked, I ran to get lotion because I’m so dang vain. But the photos I took with the smooth, perfectly moisturized, 24 year old looking hands didn’t properly show the translucence of the onions. So I present my lizard hands for you to judge.

Do you see how far I’m willing to go for cooking instructions? I give and I give! I put my scaly, decrepit paws out there and I know the world is a better place for it.

My vanity has taken me off track here. Wait, let me check out my hair.

Let’s keep making this recipe and not look at our hair.

So you’ve chopped your onions and now you’re going to squeeze your fresh lime juice. You need 1/2 cup here. Don’t argue with me.

No, you can’t use store bought lime juice. The snob has spoken. I’m sorry I’m so bossy, but someone has to protect the sanctity of flavor.

Showing the process of squeezing lime juice into a measuring up using a fork Using a fork, this is how I squeeze the juice out of the limes. I should really make a video of this. You cut the lime in half, then stab it with a fork (not too violently, you’re calm, you’re cool, you’re chillax). Then squeeze the lime juice into your container and wiggle the fork around. Stab the fork in different areas of the lime and squeeze in different directions. Keep wiggling that fork back and forth. You can get quite a bit of juice out of it by doing it this way.

If you have a juicer…good for you, but don’t make us non juicer owners jealous by bragging. We’ll just be over here crying about our misfortune while using my 15th century way of fork wiggling. Did they have forks back then? Sticks? I must google this.

Add your other ingredients and put into a storage container and toss it together like you would mix salad dressing into a salad.

Ready to marinate your onion salad in the refrigerator!

After about 3 hours, take it out and mix it again. It doesn’t have to be at exactly 3 hours. Just at some point 1/2 way through your marinating process.

Then, it will look like this:

Mixing together the marinated onions for salsa criolla The juice has gotten more pink and so have the onions. You could, if you’re feeling too impatient, serve and eat them at this point. No one is going to yell, scream, or think you’re crazy. Unless you start yelling and screaming. Then we might question what’s going on with you?

I like to give them a good 6-8 hours of marinating time or even overnight, essentially pickling them. They will start to lose some of their crunchiness if left overnight, but this is my favorite way to eat them.

What if I want a sweeter tasting onion or don’t like the bite of onion flavor?

If you don’t want a strong onion flavor, you can soak the onions in cold water for 10 minutes, drain, and pat dry before marinating. I haven’t tried this but am told it will produce a sweeter flavor.
Another option for sweeter onions is to salt the onions after slicing and massage the salt into the onions and set aside for 10 minutes. This helps the onions to sweat out that strong onion bite. Then rinse them in cold water and pat them dry.

Tips & Tricks

Cut your onions thin. A very sharp knife is best for this.
Pick out juicy limes for this recipe so it’s easier to get the full 1/2 cup of juice.
Toss and turn your onions half way through the marinating time. This will all your onions a chance to be covered with the lime juice.
If you’d like to keep these pickled onions in the fridge for a few days, you can drain out the marinade (after they’ve completed marinating) and keep in the fridge for 3-5 days. The reason you would drain the marinade is to stop the pickling process. If you’d like to keep them marinating in the lime juice for the 3-5 days you can, but they will just get softer and softer.

How do I pick out the best, juiciest limes?

Firmness:
Give them a good squeeze! Gently press your thumb and index fingertips into the lime and you should feel a little give. If it gives too much and leaves an indent in the lime, it’s too soft and past its prime. If it’s really hard, it likely has a thick rind and will be drier inside and you won’t get much juice out of it.

Color:
Limes that are all green are best and will have the best flavor. If they are a little yellow they can still be used, as long as they have a little give and are full of juice. Avoid the brown spotty ones if you can.

Weight:
Limes that are heavier likely have more juice in them than limes that are lighter.
