Ingredients You’ll Need
The beauty of this Citrus and Herb Marinated Onions Recipe lies in its simplicity. Each ingredient plays a vital role in balancing bright acidity, subtle sweetness, and herbaceous freshness, which come together to soften and flavor the onions perfectly.
- 1 medium red onion, thinly sliced: The star ingredient, its natural sharpness mellows beautifully with the marinade
- Juice and zest of 1 lemon: Provides bright, tangy notes that awaken the dish
- 2 tsp red wine vinegar: Adds complexity and a gentle acidic punch
- 1 tsp extra virgin olive oil: Brings richness and helps carry the flavors
- 1 tsp maple syrup: Balances the acidity with a hint of natural sweetness
- Kosher salt: Enhances all the flavors and helps draw moisture from the onions
- 3 tbsp minced parsley or cilantro leaves: Fresh herbs add vibrant color and a herbaceous lift
How to Make Citrus and Herb Marinated Onions Recipe
Step 1: Combine the ingredients
Start by placing your thinly sliced red onions into a medium-sized mixing bowl. Immediately add the juice and zest of one lemon, red wine vinegar, maple syrup, olive oil, a generous pinch of kosher salt, and the minced parsley or cilantro. This combination is what makes the onions both tangy and sweet, with a fresh herbal note.
Step 2: Massage the onions
Use clean hands to gently massage the marinade into the onions. This not only helps to soften their bite but also allows the flavors to infuse deeply. You’ll notice the onions start to turn more translucent—that’s a good sign they’re soaking up all that delicious marinade.
Step 3: Let it sit
Cover the bowl and let the onions rest at room temperature for 10 to 15 minutes. If you’re making this ahead, simply cover and pop it into the fridge until you’re ready to serve. The longer it marinates, the more tender and flavorful the onions become.
How to Serve Citrus and Herb Marinated Onions Recipe
Garnishes
To add an extra pop of freshness, sprinkle a few extra minced herbs like parsley or cilantro over the top just before serving. You can also add a light drizzle of olive oil or a pinch of cracked black pepper for an elegant finishing touch that complements the citrusy bite.
Side Dishes
This marinated onion is a fantastic companion to grilled chicken, fish tacos, or even a hearty steak. Its brightness cuts through rich, fatty dishes, adding balance and a burst of flavor. It also pairs wonderfully alongside Mediterranean spreads or as a tangy topping on roasted vegetables.
Creative Ways to Present
Try serving these onions atop warm avocado toast for a delightful contrast, or mix them into a grain bowl for a refreshing lift. They can also be tossed into a vibrant salad or layered into sandwiches and wraps to add a bright, crunchy snap that transforms everyday meals.
Make Ahead and Storage
Storing Leftovers
Place any leftover marinated onions in an airtight container and store them in the refrigerator. Their flavor actually deepens overnight, making them even more delicious by the next day. Consume within 3 to 4 days for the best freshness and texture.
Freezing
Because the onions are marinated and softened, freezing is not recommended as it can alter their texture, making them mushy upon thawing. It’s best to enjoy this recipe fresh or well-chilled from the fridge.
Reheating
These marinated onions are designed to be served cold or at room temperature. If you prefer a bit of warmth, gently stir them into a warm dish just before serving, but avoid heating them on their own to preserve the crisp-tender texture and vibrant flavors.
FAQs
Can I use white or yellow onions instead of red?
Absolutely! White or yellow onions will work, but keep in mind their flavor is sharper and less sweet than red onions. You might want to adjust the maple syrup slightly to balance the flavors.
Is there a substitute for maple syrup?
If you don’t have maple syrup, honey or agave nectar are excellent alternatives that will provide a similar touch of sweetness.
Can I use dried herbs instead of fresh parsley or cilantro?
While fresh herbs are best for the bright flavor and vibrant appearance, you can use dried herbs in a pinch. Use about one-third the amount of dried parsley or cilantro, but know the result won’t be quite as fresh-tasting.
How long can I marinate the onions?
The onions taste great after just 15 minutes, but marinating for several hours or overnight in the fridge intensifies the flavor and softens them further. Just be sure to cover them well.
Is this recipe vegan and gluten-free?
Yes! This Citrus and Herb Marinated Onions Recipe is naturally vegan and gluten-free, making it a fantastic addition for any dietary preference.
