Ingredients You’ll Need

• 1 red bell pepper, chopped
• 1 yellow bell pepper, chopped
• 1 medium zucchini, chopped
• 1 medium red onion, chopped
• 1 pint cherry tomatoes
• 1 lb orzo pasta
• 1/2 cup extra virgin olive oil, divided
• 1 tsp dried oregano
• Salt and black pepper to taste
• 1/4 cup fresh lemon juice
• 1 clove garlic, minced
• 1 tsp Dijon mustard
• 1/4 cup fresh parsley, chopped
• 1/2 cup crumbled feta cheese Optional
• Kalamata olives (optional)

Step-by-Step Directions

1. Preheat oven to 400°F (200°C).
2. Toss chopped red and yellow bell peppers, chopped zucchini, and chopped red onion with 2 tablespoons olive oil, dried oregano, salt, and black pepper on a large baking sheet.
3. Spread vegetables in a single even layer on the baking sheet.

4. Roast vegetables 15 minutes, then add cherry tomatoes and roast an additional 10–15 minutes until tender and caramelized at the edges.

5. While vegetables roast, bring a large pot of salted water to a boil.
6. Add orzo to boiling water and cook according to package instructions until just al dente.
7. Scoop out about 1/2 cup of the starchy pasta water, then drain the orzo well.
8. Whisk remaining olive oil, fresh lemon juice, minced garlic, Dijon mustard, chopped parsley, salt, and pepper in a small bowl to make the lemon vinaigrette.
9. Combine the cooked orzo and roasted vegetables in a large bowl.
10. Pour the lemon vinaigrette over the orzo and vegetables and gently toss to coat.
11. If the mixture seems dry, add a splash of the reserved pasta water to help the dressing cling.
12. Stir in crumbled feta and Kalamata olives if using, then serve warm or at room temperature.

Orzo and Roasting Tips

Getting the orzo just right makes a big difference. Here’s how:

• Give Veggies Room to Roast: Always spread out your veggies on the pan in a single layer for tasty caramelization. Crowded veggies steam rather than roast.
• Cook Orzo Al Dente: Orzo that’s a little firm holds up better once tossed with the dressing and veggies.
• Save Pasta Water: The starchy water is magic for turning the dressing into a light sauce that sticks beautifully to the orzo and veggies.

• Taste as You Go: Don’t forget the final taste test! A little extra lemon, salt, or fresh herbs can really lift the whole dish.

Mix-Ins and Substitutions

This roasted vegetable orzo recipe is the perfect blank canvas. Here are some ways you can make it your own:

• Protein Boost: Add grilled chicken, shrimp, or chickpeas to turn it into a hearty main dish.
• Veggie Swaps: Use seasonal favorites like asparagus and peas in spring or hearty butternut squash and broccoli in the fall.
• Greens Galore: Stir in fresh spinach or arugula at the last minute for added crunch and freshness.
• Add Heat: A pinch of red pepper flakes in the vinaigrette gives the dish a nice kick.

This dish is satisfying enough to serve on its own or pairs beautifully with grilled fish like salmon or simple roasted chicken. For meat-free meals, add some crusty bread and a fresh green salad. It’s also a showstopper at potlucks and family gatherings.
