Ingredients You’ll Need
This is one of those recipes where every single ingredient is essential—each one plays an important role in building the final burst of flavor, texture, and color that makes Simple Sumac Onions so irresistible. The list is short and sweet, just the way we like it, but don’t be fooled; the combination is magic!
- 1 large red onion (thinly sliced): Red onions add a striking color and a crisp, punchy bite but mellow beautifully with the marinade.
- 1 tablespoon ground sumac: The secret star of this dish! Sumac brings bright, citrusy tang and its gorgeous ruby-red hue.
- 1 tablespoon fresh lemon juice: Lemon amps up the tartness and helps soften the onions, making them utterly snackable.
- 1 tablespoon olive oil: The olive oil rounds things out, adding silkiness and balance to the acidity.
- ½ teaspoon salt: Don’t skip this—salt draws out moisture and tempers the bite of raw onion, while making all the flavors pop.
- 2 tablespoons chopped fresh parsley (optional): A sprinkle of parsley brings a burst of fresh, herbal aroma and a pop of green.
How to Make Simple Sumac Onions
Step 1: Slice the Red Onion
Start with a large, sharp knife and thinly slice your red onion. The thinner, the better—thin slices soak up flavor more quickly and make for a delicate crunch. If raw onion is a bit strong for your taste, you can soak the slices in icy water for 10 minutes, then drain and pat dry. This little trick tames the sharpness and keeps the crunch.
Step 2: Combine the Ingredients
Add the thinly sliced onions to a medium mixing bowl. Sprinkle over the ground sumac, then drizzle in the lemon juice, olive oil, and salt. Give everything a thorough toss with your hands or tongs, making sure every strand of onion gets an even coating. This step is where the transformation begins—the sumac and lemon start to soften and infuse the onions right away.
Step 3: Let the Flavors Mingle
Set the bowl aside and let your Simple Sumac Onions rest for 10 to 15 minutes at room temperature. During this time, the onions will slightly wilt as they absorb all the tangy, salty, and citrusy flavors. If you’re in a hurry, even 5 minutes will give you a delicious result, but that little bit of patience pays off deliciously.
Step 4: Add Parsley and Serve
Right before serving, toss in the chopped fresh parsley if you’re using it. The herby freshness is especially nice if you’re serving the onions as a salad or topping for grilled meats. Give everything one last toss and taste for seasoning—add a pinch more salt or lemon juice if you love bold flavors. Grab your forks (or wraps, or kebabs!) and enjoy!
How to Serve Simple Sumac Onions

Garnishes
While Simple Sumac Onions are perfectly delicious on their own, a sprinkle of toasted sesame seeds or an extra dusting of sumac can make the presentation pop and add another layer of texture. Don’t be afraid to finish with a drizzle of pomegranate molasses for an irresistible sweet-sour twist.
Side Dishes
Pair your Simple Sumac Onions with everything from smoky kebabs and juicy lamb chops to shawarma wraps and crisp falafel. They also shine alongside grain salads, rice pilafs, or a platter of creamy hummus and warm pita, adding instant brightness and crunch.
Creative Ways to Present
For a show-stopping appetizer, pile these onions onto crostini smeared with labneh or yogurt. Try folding them into an herby egg salad, tucking them inside tacos, or layering them on mezze platters. Their vivid color and bold flavor always steal the show!
Make Ahead and Storage
Storing Leftovers
Leftover Simple Sumac Onions will keep beautifully in the fridge for up to 4 days, tightly covered. In fact, some say they get even more delicious as the flavors deepen and mellow. Just give them a quick toss before serving again!
Freezing
Freezing isn’t ideal for Simple Sumac Onions because their wonderful crisp-tender texture can turn a little soggy once thawed. It’s best to make a fresh batch—after all, they take just minutes to whip up!
Reheating
No reheating needed! Simple Sumac Onions are meant to be served fresh and cool, straight from the fridge or at room temperature. If they’ve been chilled, let them sit out for a few minutes to take the chill off before serving.
FAQs
Can I use yellow or white onions instead of red?
Red onions are preferred for their sweet flavor and stunning color, but you can substitute with yellow or white onions in a pinch. Just keep in mind the flavor will be sharper, so a brief soak in cold water is even more helpful.
Where can I find sumac?
Sumac is widely available at Middle Eastern grocery stores, specialty spice shops, or online. Look for a deep magenta, lemony powder—once you try it in these Simple Sumac Onions, you’ll want it on everything!
Is this recipe spicy?
Nope! Simple Sumac Onions are all about tanginess, not heat. If you want to add a spicy kick, feel free to toss in a pinch of red pepper flakes or thinly sliced chili.
Can I make Simple Sumac Onions ahead of time?
Absolutely! They’re great made a few hours in advance or even the day before, giving the flavors time to meld. The onions will soften a bit and the sumac flavor becomes more pronounced, which many people absolutely love.
Are Simple Sumac Onions vegan and gluten-free?
Yes! They’re 100% vegan and naturally gluten-free, making them the ultimate versatile side dish or topping for almost any gathering.
