Vegan Couscous Salad Ingredient Highlights


I like to use pearl couscous in this recipe, which is just a little bit larger than regular couscous, but you can use either!

Cook the couscous in broth instead of water to infuse flavor. You can buy vegetable broth at the supermarket or make your own from vegetable scraps.

You can use a slicing tomato, beefsteak tomato, vine ripe tomato, or even cherry or grape tomatoes.

Vegan Couscous Salad Tips and Tricks


How to Make Flavorful Couscous

Couscous is a tiny pasta made of wheat or barley, that’s rolled into a little ball. Similar to rice, it soaks up the flavor of whatever you cook it in.

There are two common types of couscous that you can typically easily find at your supermarket. The first, pearl couscous, is larger, just like the ones pictured here. This recipe calls for 1 cup of uncooked pearled couscous.

The other common type of couscous is Moroccan. It is very small, almost resembling grits or semolina. It can easily be used in place of Israeli couscous in this recipe, substituting 1 cup of pearl couscous for 1 cup of Moroccan couscous.

The best way to infuse extra flavor into your couscous is by actually cooking it in vegetable broth. Bring the couscous and veggie broth to a boil in a medium-sized pot.

Then, reduce the heat to low, cover, and simmer for 20 minutes until the couscous is tender.

Dress Your Couscous While Its Hot

Once your couscous is cooked, transfer it to a large bowl. Add the olive oil and lemon right away while the couscous is still hot and toss to coat.

This will ensure your couscous doesn’t stick together and also allow the couscous to really soak up the flavor of both the lemon and olive oil.

How to Prep Your Tomatoes

Rinse your tomatoes and slice it into thin strips. Cut out the stem and dice the tomatoes into small, bite-sized pieces.

While the pieces of tomato certainly do not have to be perfectly uniform, getting everything roughly equal in size is the best way to get every element in each bite.

You can use a standard slicing tomato, a vine ripe tomato, or a beefsteak tomato. You can even use about a half of a pint of cherry tomatoes. Whichever tomatoes you use, make sure you’re dicing them.

If you don’t have a tomato knife or high-quality chef’s knife, you may find a serrated knife is easier to use to pierce the skin of the tomato.

Prep Your Cucumbers for the Couscous Salad

The cucumber brings so much freshness and crunch to each bite. Use a sharp knife to chop off the ends and slice the tomato into strips about ½-inch thick.

Then, you can lay your slices flat to easily dice them into bite-sized pieces, roughly the same size as the tomatoes.

I just rinse the cucumbers and leave the skin on, but if your preference is to peel your cucumber, you certainly can do so with a vegetable peeler.

How to Easily Dice Basil

While your instinct may be to remove your basil leaves from the stems, I encourage you to leave them on! The stems are perfectly edible and super flavorful.

To dice the basil, start by washing and drying it. Place it on a dry cutting board, then stack a few leaves and stems together.

Roll the stacked leaves and stems them tightly and slice across to create thin strips. Turn the strips and cut perpendicular to make small, even pieces.

How to Dice Your Avocado

Use a sharp knife to slice your avocado in half lengthwise. Pull the two halves apart. The pit will stay whole and remain in one half of the avocado. Remove it and discard it.

Then, you can use your knife to dice the avocado flesh while it is still in its outer rind. From there you can scoop the avocado flesh out from the rind with a spoon directly into your couscous salad.

If you open and dice your avocado early while your couscous still has a while to cook, squeeze a little bit of lemon juice on top to keep it from browning.

Season and Toss Your Couscous Salad

Once your couscous has had a little time to cool, add your prepped tomato, cucumber, basil, and avocado. Then, add the salt and pepper.

Use two forks to toss everything together, fluffing the couscous as you do so. Taste to see if you need any additional salt and pepper. And voila! You’ve got a super refreshing and delicious little pasta salad!

How to Store Leftover Couscous Salad

Ideally, it’s best to eat this couscous salad fresh for the best texture on all the veggies and to avoid browning from the avocado.

The couscous alone will stay fresh covered in the refrigerator for about 5 days. You can always add the remainder of your ingredients fresh when you’re ready to eat it!

The good news is, if you do have leftovers, the lemon will help to keep the cucumber, avocado, tomato, and basil fresh for 2-3 days.

Store it in an airtight container in the refrigerator and enjoy it cold.
