The oven does most of the work here. While a tray of vegetables browns, the pasta boils, and the two come together with lemon, herbs and a little pasta water. Whole-wheat pasta has a nutty flavor that stands up well to sweet roasted peppers and onions, and you can use whichever vegetables you have.
Serves: 4 | Time: about 45 minutes, mostly hands-off
Ingredients
Vegetables
- 1 medium zucchini, sliced into half-moons
- 1 red and 1 yellow bell pepper, cut into bite-size pieces
- 1 small red onion, cut into wedges
- 1 small eggplant, cubed
- 2 cups broccoli florets
- 1 cup cherry tomatoes
- 3 tablespoons extra-virgin olive oil
- 4 garlic cloves, thickly sliced
- 1 teaspoon dried oregano
- ½ teaspoon smoked paprika
- ½ teaspoon salt and ½ teaspoon black pepper
Pasta and finish
- 340 g (12 oz) whole-wheat penne, fusilli or rigatoni
- 2 tablespoons lemon juice and 1 teaspoon lemon zest
- 2 tablespoons chopped parsley
- ¼ cup grated Parmesan (optional)
- 2 tablespoons toasted pine nuts or chopped walnuts (optional)
Method
- Heat the oven to 425°F (220°C). Use one very large rimmed tray or two smaller ones.
- Toss the zucchini, peppers, onion, eggplant, broccoli and tomatoes with the oil, oregano, paprika, salt and pepper. Spread them out in a single layer.
- Roast for 15 minutes. Stir, add the garlic, and roast for another 10 to 20 minutes, until the edges are browned and the centers tender. Adding the garlic later keeps it from burning.
- Meanwhile, boil the pasta in salted water, tasting early as whole-wheat pasta can go from firm to soft quickly. Save 1 cup of the water and drain.
- Return the pasta to the pot. Scrape in the vegetables with all their tray juices, and add the lemon juice and zest.
- Add a splash of pasta water and toss hard for about a minute, adding more as needed, until lightly glossy.
- Stir in the parsley, taste for salt and lemon, and top with cheese and nuts if using.
Tips for better roasting
- Give them space. Crowded vegetables steam instead of browning. If they are touching heavily, use a second tray.
- Size by density. Cut firm vegetables, such as carrots, smaller than soft ones, such as zucchini, so they finish together.
- Keep the oil modest. The pieces need a light coat. Too much makes the finished pasta greasy.
- Add lemon last. It stays fresh and balances the sweetness of the vegetables.
Swaps and additions
- Other vegetables: Mushrooms, carrots, cauliflower and asparagus all work. Asparagus only needs the last 10 to 12 minutes.
- Frozen vegetables: Roast from frozen on a hot tray with plenty of space. They release more water and brown less.
- More protein: Add canned chickpeas or white beans to the tray for the last 15 minutes, or top with grilled chicken or shrimp.
- Mediterranean: Finish with olives and crumbled feta.
- Creamy: Stir in a few spoonfuls of ricotta off the heat, loosening it with pasta water.
- Vegan: Skip the Parmesan and use the nuts. Check the pasta label for egg.
Which pasta to use
Fusilli holds herbs and juices in its twists, penne is sturdy and familiar, and rigatoni gives a bigger bite. For a deeper look, see the pasta pairing guide and our notes on types of pasta. Regular pasta works too if you prefer it.
Storage and meal prep
Refrigerate leftovers in an airtight container and eat them within 3 to 4 days. Reheat in a pan over medium-low heat with a splash of water, then add fresh lemon or parsley. Leftovers also make a good cold pasta salad with some greens added. For meal prep, keep the vegetables and pasta in separate containers and combine them when you eat.
Frequently asked questions
Is whole-wheat pasta healthier than regular pasta?
It generally has more fiber, and it keeps more of the whole grain. The Harvard T.H. Chan School of Public Health has a useful guide to whole grains. Overall portion size and the rest of your diet still matter.
Why doesn’t this have a thicker sauce?
The vegetables are the main flavor. The oil, tray juices and pasta water just form a thin coating to carry them.
What cheese goes best with it?
Parmesan, Pecorino Romano or crumbled feta all work. Use a light hand so the vegetables still come through.
