Hello, beautiful.

Warm Quinoa and Arugula Salad with Lemon Dressing

You should know that I’ve been wanting to post about this salad for a looong time. Ever since I started this blog, in fact. It’s a copycat of my favorite salad at (probably) my favorite restaurant in Salt Lake, Caffe Niche. But every time I’ve made it, it hasn’t quite lived up to the restaurant version, and I had to get it juuust right. But I think I finally did!

It is just as good as it sounds – the nutty flavor of the quinoa, the sweetness of the roasted vegetables, and the bite of the lemon and arugula all combine to make my perfect salad.

The restaurant serves this in full or half portions. I always get the full salad, telling myself I’ll take the other half home. It hasn’t happened once! I’m a goner as soon as I take the first bite.

This is the kind of salad that you order for lunch on a sunny restaurant patio on a warm spring day. Preferably with a glass of red wine! It’s satisfying but still light, and although I love the salad warm, the leftovers (if you manage to save any!) are excellent cold.

Can I cram any more pictures in here to convince you to make this salad ASAP? Well, maybe just a few.

Man I hate caramelizing onions – it always feels like a project. So I just tossed ’em in the oven with the tomatoes, which cut down on the cooking time (and dishes!), and still gives them a great sweet flavor.

Also, I think I about quadrupled the amount of tomatoes from the restaurant version. I don’t want them hiding in there, you know? I love that my take on the salad is just bursting with juicy roasted tomatoes.

I highly recommend putting this on your summer menu!

Have a good weekend, and happy Cinco de Mayo! No Mexican recipes from me this Cinco de Mayo, unfortunately… maybe I’ll get my act together for that next week :)

  • 2 tsp olive oil, divided

  • 2 pints grape or cherry tomatoes
  • 1 cup dry red quinoa
  • arugula
For the dressing:

  2. In the meantime, add quinoa to a pot with 1 1/2 cups water. Bring to a boil and simmer until tender, about 12-15 minutes. Drain excess water.
  3. While quinoa and vegetables are cooking, prepare the dressing by blending all ingredients together.
  4. Once quinoa and vegetables are ready, stir them together with half of the dressing. Serve on a bed of arugula with extra dressing alongside. You may have leftover dressing.
  5. Enjoy!

    I’m melting all over my couch right now. This looks so healthy and tasty!! I love trying to re-create my favorite restaurant recipes at home and as far as I’m concerned, this salad looks perfect!

    This is exactly the recipe I was looking for! I knew I wanted a quinoa arugula salad with roasted tomatoes and caramelized onions, and now I have the perfect dressing too! One question – what is prepared mustard? Is that the same thing as mustard powder?

    Thank you for the recipe – I’m excited to try it!

      Hi Miranda! No, prepared mustard is just the regular condiment in the jar, as opposed to mustard powder. Hope you enjoy the salad!

        I ended up subbing mustard powder and a splash of white wine vinegar since I didn’t have any prepared mustard on hand. And it was DELICIOUS! I have quinoa on the stove and veggies in the oven again right now in fact. Thank you so much for the recipe, Erica – it’s my new favorite salad!
