Now, before you plunge into making this vinaigrette, let’s chat about the ingredients. Fresh basil is a must; it brings a garden-fresh aroma that you just can’t replicate with dried herbs.
And when it comes to sweet onions, they’re your best friend here. Think Vidalia or Walla Walla—they’ll give you that lovely caramelized sweetness when grilled. I mean, who doesn’t love the smell of onions sizzling away on the grill?
Just be careful not to cut the slices too thin; you want them to hold up nicely while cooking. Plus, a little bit of sugar in the mix helps to balance out the acidity, making your vinaigrette taste downright irresistible.
How to Make Sweet Onion Vinaigrette

Making Sweet Onion Vinaigrette is a delightful culinary adventure, and it all starts with a food processor. Grab your 1/4 cup of lemon juice and 1/4 cup of white wine vinegar, and toss them into the processor. Then add in 1/4 cup of fresh basil, chopped—this is where that garden-fresh aroma begins to dance around your kitchen.
Next, pour in 3 tablespoons of extra virgin olive oil and a tablespoon of Dijon mustard. Don’t forget the 1/2 teaspoon of sugar, 1/2 teaspoon of salt, and 1/2 teaspoon of black pepper, plus those three garlic cloves, minced to perfection. Now, let’s hit that puree button and blend everything together until it’s smooth. You might want to take a moment to admire your handiwork—it’s already looking so vibrant.
Once you’ve got that beautiful vinaigrette, pour it into a bowl and let it sit at room temperature for about an hour. This waiting period is essential because it allows those flavors to mingle and create a symphony of taste.
While your vinaigrette is chilling out, it’s time to turn your attention to the star of the show—your large sweet onion, which you’ve already sliced into 1/2 inch pieces. Fire up the grill and once it’s nice and hot, toss those onion slices on there. Keep an eye on them; you want them to get that lovely char without turning into mush. Once they’re grilled to your liking, take them off and let them cool just a bit.
Now comes the fun part. Add those grilled onion slices right into your vinaigrette, giving everything a gentle stir. The sweet, smoky flavor of the grilled onions will infuse your vinaigrette with a delicious depth.
Serve it all up at room temperature over your favorite grilled veggies, and just watch your friends and family swoon. It’s a sweet and tangy delight that might just become a staple in your kitchen. And hey, if they ask for seconds, just play it cool—it’s all in a day’s work for a vinaigrette virtuoso like yourself.
Sweet Onion Vinaigrette Substitutions & Variations
After whipping up that delightful Sweet Onion Vinaigrette, you might find yourself wanting to mix things up a bit.
One easy substitution is to swap the white wine vinegar for balsamic vinegar, which adds a richer flavor. If you’re in the mood for a zestier kick, try adding a splash of apple cider vinegar instead.
For a herbaceous twist, incorporate fresh herbs like parsley or cilantro in place of basil. You can also experiment with different oils—avocado oil works beautifully!
If you prefer a milder taste, consider using shallots instead of sweet onions.
Finally, a touch of honey or maple syrup can enhance sweetness without the sugar.
Let your creativity run wild, and enjoy the process!
What to Serve with Sweet Onion Vinaigrette
While you can enjoy Sweet Onion Vinaigrette on its own, pairing it with the right dishes elevates its flavor even more.
I love drizzling this vinaigrette over grilled vegetables like zucchini, bell peppers, and asparagus. The sweetness of the onions complements the smoky char perfectly.
You can also toss it with mixed greens for a revitalizing salad that’s bursting with flavor. If you’re feeling adventurous, try it on roasted chicken or fish; the vinaigrette adds a delicious zing.
For a simple yet satisfying meal, serve it alongside quinoa or couscous, allowing the vinaigrette to soak into the grains.
Trust me, once you experience these pairings, you won’t want to go back!
Additional Tips & Notes
When you’re ready to elevate your Sweet Onion Vinaigrette experience, a few tips can make all the difference. First, let that vinaigrette sit at room temperature for at least an hour; it allows the flavors to meld beautifully.
If you want a smoother texture, try blending the grilled onion into the vinaigrette instead of leaving it chunky. I also love adding a pinch of fresh herbs like thyme or oregano for an extra layer of flavor.
Don’t forget to adjust the seasoning to your taste; a dash more salt or a squeeze of lemon can really brighten things up.
Finally, this vinaigrette keeps well in the fridge, so feel free to make a larger batch for future meals!
