Ingredient Notes

All of the ingredients gathered for making a vegan roasted vegetable orzo recipe. Each ingredient is labelled with text and the list can be found on the corresponding blog page.

A complete list of ingredients with amounts and full instructions is located in the printable recipe card below. This section covers ingredient and substitution considerations.

  • Orzo: Orzo is a small rice-shaped pasta. Be sure to read the label if you’re vegan as some brands contain eggs.
  • Red Bell Pepper: The recipe calls for red bell pepper but orange or yellow bell pepper would also work.
  • Zucchini: You’ll need one small fresh zucchini.
  • Red Onion: One small or half a large red onion. Red onion is best here but you could use a white onion if that’s all you have.
  • Tomato: Use cherry tomatoes or grape tomatoes.
  • Garlic: Use 2 cloves of garlic of if needed, you can substitute 1 tsp garlic granules.
  • Dried Herbs: You’ll need dried thyme and oregano. You can substitute 2 tbsp each of minced fresh herbs if you like.
  • Lemon: You’ll need 1 fresh lemon to make the lemon zest and lemon juice.
  • Olive Oil: A good quality extra virgin olive oil works best here. I wouldn’t recommend another oil.
  • Parsley: Optional but adds some freshness when mixed in at the end. Basil would also be nice!

Step-by-Step Photos

Step 1: Roast the Vegetables

Preheat the oven to 425 degrees F. Chop up all your veggies, cutting roughly the same bite-sized pieces for everything, and add them to a large sheet pan in a single layer.

Add 1/2 a tablespoon (1.5 tsp) of the olive oil, the thyme and oregano, and a pinch of salt and pepper. Roast the veggies for about 30 minutes, stirring them halfway through.

QUICK TIP: Use a large baking sheet, or two if needed, so the veggies can lay in an even layer with room to breathe.

When they’re piled on top of each other they tend to steam rather than roast so be sure to give them some room so they get perfectly roasted and caramelized!

Step 2: Cook the Orzo

Once the veggies are in the oven, start bringing a large pot of salted water to a boil. Once it’s boiling, cook your orzo according to the package instructions. Once it’s done, drain and add to a large mixing bowl or serving bowl.

I prefer orzo cooked al dente, which was 6 minutes of cooking time for the brand I used. It can vary from 5-10 minutes though, so check the package for instructions.

Step 3: Mix the Vinaigrette

In a small bowl, whisk together the remaining olive oil, garlic, lemon juice, lemon zest and a pinch of salt and pepper.

Quick Tip: Use a citrus planer or garlic press to get the garlic nice and smooth, almost like a paste!

Step 4: Combine and Enjoy!

Once the veggies are done, add them to the bowl with the orzo along with the vinaigrette and chopped parsley and mix everything up.

That’s it! Serve the orzo right away for a hot pasta or chill in the fridge until serving for a cold dish.

For serving, try sprinkling with more parsley and fresh cracked black pepper, lemon and/or fresh basil leaves, if you like!

Variations & Additions

  • Mix in a few handfuls of spinach or baby kale at the end.
  • Add a can of white beans or chickpeas at the end for more protein and texture.
  • Add 1/2 cup sun-dried tomatoes and/or black olives or kalamata olives at the end.
  • Roast 1 cup of corn kernels with the veggies or add them at the end.
  • If you have a grill, try using a grill basket to make grilled vegetables for this dish! Perfect for summer.

FAQs

Do I have to use orzo?

No. You can make this recipe with any short pasta shape like penne, farfalle, rotini or fusilli. You could also use a long pasta shape like spaghetti or linguini, I just prefer smaller shapes for this recipe.

Is this recipe gluten-free?

No. Regular orzo is made from wheat so the recipe is not gluten-free. If you can find gluten-free orzo, use that, or substitute any short shape of gluten-free pasta like brown rice pasta or chickpea pasta.

What vegetables can I use in this recipe?

This recipe works well with tomatoes, zucchini, any colour of bell pepper, mushrooms, shallot, onion, asparagus, green beans, carrot or broccoli.

Use roughly 4-5 cups of chopped vegetables in total.

If you use hardier veggies like sweet potato, carrot, Brussels sprouts, etc. I would roast them on a separate pan and get them in the oven about 10 minutes before things like bell pepper, zucchini and tomato since they take a bit longer to cook through.

Can you freeze orzo with roasted vegetables?

Technically, yes, you could freeze this recipe but it’s not really an ideal freezer recipe. The veggies wouldn’t have the best texture after thawing.
