Roasted Veg Vinaigrette

Vinaigrettes are equally as important to me as their salad counterparts. With a proper choice of ingredients, one can really make a salad burst with flavor with a perfectly paired vinaigrette.

I’ve posted before on vinaigrettes made with reduced beet juice ( think salad of crunchy vegetables, lentils and goat cheese) and a vinaigrette made with a fresh pear (think baby greens with apples, bacon, and blue cheese).

I’ve posted on a vinaigrette made with strawberry vinegar, one made with pineapple juice, vinaigrettes with parsley or curry powder… the list is really endless because the possibilities are endless.

Recently I was inspired by a vinaigrette recipe made with roasted onion and shallot. And I got to thinking what I could add to that… because I can’t leave a recipe alone. This is one I created.

Beyond roasting the vegetables, which is left to your oven, the rest is easy!

Make a triple batch! You’ll love how versatile this is. Serve with grilled leeks or asparagus.

Roasted Vegetable Vinaigrette

1 purple onion, peeled, quartered
1 red bell pepper, trimmed, de-seeded, cut into 8ths
6 shallots, peeled, halved
6 cloves garlic, peeled
Olive oil, divided
Red wine vinegar
Tabasco sauce (optional)

Preheat the oven to a roast setting, or 400 degrees F.

Place the onion, red bell pepper, shallots and garlic cloves on a jelly roll pan or rimmed roasting sheet. Generously drizzle olive oil over the vegetables, about 1/4 cup. Season with salt and pepper.

Roast until vegetables show some caramelization and are tender. Remove the pan from the oven and let cool.

Place all of the vegetables and olive oil into a blender jar.

Blend until smooth, adding another 1/4 cup or so of olive oil.

Then add the red wine vinegar. I’m not offering amounts in this recipe, only because I like my vinaigrettes strongly vinegar-flavored. Most people I’ve cooked for do not.

If you want some zing, add some Tabasco sauce, taste away, and season more if necessary. Taste for salt.

Make sure the vinaigrette is smooth. If you use cruets for your vinaigrettes, you are familiar with the problem with one little piece of garlic clogging the spout!

The salad I created to showcase this vinaigrette was simple. Butter lettuce, crab, avocado, green onions, and black sesame seeds.

It was a perfect pairing of tastes and textures.

I was lucky enough to have frozen crab legs left over from the holidays, so I used that crab. But grilled shrimp or scallops would also be divine.

Note: This recipe actually makes a fabulous dipping sauce if you omit the vinegar.

    I have never used roasted veggies in a vinaigrette before. I so need to try your recipe!

    • chef mimi January 28, 2019 at 12:40 PM - Reply

      I hope you like it! It truly was good without the vinegar as well. I played a little!

    The dressing sounds amazing! I love to try new ideas for salads!

      Thank you! Nothing much better than roasted vegetable flavors.

    This is brilliant! Never thought about roasting veggies and turning them into a vinaigrette! Bet it’s so flavorful and I’m going to try it over roasted salmon. YUM!

    • chef mimi January 28, 2019 at 12:40 PM - Reply

      You’ll love it! Or just let them become a sauce and forget the vinegar. Really yummy!

  8. jenniferguerrero1 January 28, 2019 at 11:35 AM - Reply

    That looks divine. I’m a sucker for a gorgeous protein salad. And that dressing was produce-filled, too. I’ve got to go and find your reduced beet dressing. I’ve been in a beet mood lately.

    • chef mimi January 28, 2019 at 12:39 PM - Reply

      I’ll just buy canned beets, and save the juice. The reduction can have so many uses!

  9. Liz @ spades, spatulas, and spoons January 28, 2019 at 12:23 PM - Reply

    What a great idea! I can see lots of uses for this, even as a sauce for fish or chicken. I have a similar problem with vinegar, I like my dressings quite tart and it isn’t always to everyones liking.

    • chef mimi January 28, 2019 at 12:38 PM - Reply

      When I catered and cooked for a family, I was barely allowed to use vinegar!

  10. Laura January 28, 2019 at 2:04 PM - Reply

    What a lovely dressing, Mimi! I personally love vinaigrettes and often use a 1:1 ratio rather than the 1:3 (vinegar:oil) a lot of folks like. But I think the Roasted veggies as a dressing is awesome, and I’ve never even considered it! Thanks so much for this recipe, Mimi!

    • chef mimi January 28, 2019 at 5:30 PM - Reply

      That’s the ratio I use as well. Sometimes even more vinegar… I hope you get to try this!

    That is one delicious looking salad. I don’t think I’ve ever had a vinaigrette quite like this. I’m already thinking of what I want to put it on beyond salad. I think it could also be a dip, a sauce, spread into a sandwich. Love!

    • chef mimi January 30, 2019 at 6:47 AM - Reply

      Exactly! Before I turned it into a vinaigrette I was dipping all kinds of things in it! It would be great with fried Haloumi!

    Mimi, your crab salad looks amazing and yummy. I love vinaigrettes, but I’ve not made a roasted onion one. It sounds wonderful and I’m with you the more vinegar the better (to a point). I believe your vinaigrette will play well on a salmon sashimi salad we like.

    • chef mimi January 30, 2019 at 6:45 AM - Reply

      Oooh, that does sound good! You’re so lucky to get good fish where you live.

    I can never leave a recipe alone, either. Fun to play in the kitchen, isn’t it? And gosh, looking what you’ve come up with — this is genius! Really excellent — thanks.

    i love the idea of blending veggies into vinaigrette! the roastedness would add such a nice sweetness, and it looks like the vinaigrette has such a great body because of all the veg.

    • chef mimi January 31, 2019 at 6:59 AM - Reply

      It definitely has a lot of body to it; it’s not runny. And the flavor is wonderful!

      Thanks! It’s very tasty and quite versatile. I’m already excited to make it again.

    • chef mimi February 1, 2019 at 6:46 AM - Reply

      Thank you Susan! It was a fun thing to try. Alternately I could have just roasted vegetables and onions and put them on the salad!!!

    LOVE this! And we like our vinaigrettes vinegary, too. Will be making this soon.

    • chef mimi January 31, 2019 at 10:14 AM - Reply

      Thanks! Try it without the vinegar first. I really also like it as a sauce/dip!

    • chef mimi February 1, 2019 at 6:45 AM - Reply

      When I make salads for lunch, I will just pour on the vinegar(s). No real need for oil when I’m not actually preparing a vinaigrette!

    Firstly I know this recipe is about your roasted veg vinaigrette Mimi, but that salad looks amazing! I can imagine the flavours of the vinaigrette complimenting it perfectly. Nice. Very nice!

      Thanks so much Neil! The crab turned out pretty good considering I can only get real crab frozen. It was still a treat for me!

      I even eat salads during winter months, which some people find strange. Occasionally if I’m chilled I do have a hot meal.

      Exactly! And it they’re not on the salad, they might as well be in the vinaigrette!

    A very unusual (and fantastic!) vinaigrette recipe! Nowadays I’m crazy for Ceasar sauce and have almost forgotten the old good vinaigrette and its variations… but it’ll come back with spring, I’m sure because the sunnier the days, the more vinaigrette I make! Thank you for bringing some sunshine with this wonderful idea!

      I understand that. It really makes sense. Me, I have salads year round. Unless I’m chilled and really need something warming!

    Simply luscious. I make a similar vinaigrette with shallots only. The addition of more veg makes this appropriate to more than just salads. Asparagus as you say sounds good, but I bet fish would love to swim in this vinaigrette as well. GREG

      You’re too kind! I just love playing in the kitchen. I think we had so many lean year when I had to be creative with my cooking so as to not waste one carrot, that it turned me into what I do today in the kitchen. I still don’t like to waste food, but it also promotes creativity to “use what you already have.”

    A good vinaigrette makes the salad. In some ways, I think, it’s more important than what is in the salad. See you!
