Sumac Marinated Onions

Sumac marinated onions, also known as Turkish onion salad, are a delicious topper for salads, proteins or rice bowls. Thinly sliced red onion is tossed with olive oil, lemon juice, parsley, sumac and salt, then marinated for an hour to help the flavors come together.

These onions are a staple in Turkish cuisine, traditionally served with meat, but delicious on salmon bowls or savory breakfast plates.

This simple condiment will keep fresh in the fridge for up to 4 days. It absorbs more flavor the longer it sits, so can be made ahead of time for an easy meal prep.

Sumac is a popular middle-eastern spice that adds a slight tangy flavor to salads or marinades. Sumac adds a subtle lemon flavor, and is made from dried and ground berries of the wild sumac flower. I love using it on slow-roasted salmon or stuffed olives for a little extra kick.

These onions pair perfectly with a side of grilled salmon or a cottage cheese breakfast bowl for some added zesty flavor.
