Roasted Vegetable Orzo

Roasted Vegetable Orzo is the kind of colorful, satisfying side dish that quietly steals the table. Tender orzo is tossed with caramelized bell peppers, zucchini, red onion, and juicy roasted tomatoes. A bright lemon-Dijon dressing keeps every bite fresh, while Parmesan adds just enough savory richness.

It is simple enough for a weeknight, yet polished enough for a holiday spread or summer gathering. The vegetables roast while the pasta cooks, so the whole recipe comes together without fuss. Serve it warm, at room temperature, or chilled the next day. The flavors only become more delicious as they mingle.

This roasted vegetable orzo is flexible, dependable, and easy to pair with chicken, fish, or grilled meats. It also makes a lovely vegetarian lunch all on its own. Colorful food somehow feels more cheerful, and this bowl brings plenty of both.

Recipe Yield: 6 servings

INGREDIENTS

1 1/2 cups dry orzo
1 medium red bell pepper, cut into 3/4-inch pieces
1 medium yellow bell pepper, cut into 3/4-inch pieces
1 medium zucchini, cut into 3/4-inch pieces
1 small red onion, cut into thick bite-sized pieces
1 1/2 cups cherry tomatoes
5 tbsp extra-virgin olive oil, divided
1 1/4 tsp kosher salt, divided
1/2 tsp black pepper, divided
1/2 tsp smoked paprika
2 tbsp fresh lemon juice
1 tsp finely grated lemon zest
1 tbsp red wine vinegar
1 tsp Dijon mustard
1 tsp honey
1 small garlic clove, finely grated
1/4 tsp crushed red pepper flakes, optional
1/3 cup finely grated Parmesan cheese
1/4 cup chopped fresh flat-leaf parsley
2 tbsp chopped fresh basil

INSTRUCTIONS

1. Preheat and prepare:
Preheat the oven to 425°F. Line two large rimmed sheet pans with parchment paper.

2. Season the vegetables:
Combine the bell peppers, zucchini, onion, and tomatoes with 3 tbsp olive oil, 1 tsp salt, 1/4 tsp black pepper, and smoked paprika. Divide between the pans in a single layer.

3. Roast until caramelized:
Roast for 22–28 minutes, stirring and rotating the pans halfway through. The vegetables should be tender with browned edges, and the tomatoes should begin to burst.

4. Cook the orzo:
Meanwhile, cook the orzo in well-salted boiling water until just al dente. Reserve 1/3 cup pasta water, then drain without rinsing.

5. Make the dressing:
Whisk the remaining 2 tbsp olive oil, lemon juice, lemon zest, vinegar, Dijon, honey, garlic, remaining salt, remaining pepper, and crushed red pepper.

6. Toss the orzo:
Add the warm orzo to a large bowl with the dressing and Parmesan. Toss well, adding 2–4 tbsp reserved pasta water until glossy and evenly coated.

7. Finish and serve:
Gently fold in the roasted vegetables, parsley, and basil. Rest for 5 minutes, then taste and adjust the seasoning before serving warm or at room temperature.

HELPFUL TIPS TO PERFECT THIS RECIPE

• Give the vegetables space: Dividing them between two pans allows their edges to caramelize. Crowded vegetables release steam and become soft rather than beautifully roasted.
• Keep the orzo slightly firm: Drain it as soon as it reaches al dente. It will continue absorbing the lemon dressing as the dish rests.
• Dress the pasta while warm: Warm orzo absorbs flavor more evenly and helps the Parmesan melt into a light, savory coating.
• Refresh leftovers before serving: Refrigerate for up to four days. Add a small splash of lemon juice and olive oil to restore the fresh, glossy texture.
