Can I make this gluten-free?

Absolutely! Just substitute your favorite gluten-free pasta. Cook it according to package directions plus one minute (rather than two) as gluten-free pasta can become too soft more quickly. The rest of the recipe remains exactly the same.

How do I prevent my pasta salad from drying out the next day?

This is where our pro tip comes in handy! Before draining your pasta, reserve some of the starchy cooking water. Mix 3 tablespoons of this water with a portion of your dressing and set aside. When you're ready to serve leftover pasta salad, bring it to room temperature and toss with this reserved dressing mixture. The starch in the pasta water helps the dressing cling to the pasta, keeping everything moist and flavorful.

Can I grill the vegetables instead of roasting them?

Yes! Grilling gives an even more wonderful smoky flavor. Keep the vegetables in slightly larger pieces so they don't fall through the grates, and watch them carefully as grilling times may vary. You'll still want to marinate them in the dressing while warm.

Is there a dairy-free version of this recipe?

You can easily make this dairy-free by omitting the feta or replacing it with a dairy-free alternative. Many brands now make excellent plant-based feta substitutes. You could also add some nutritional yeast to the dressing for a cheesy flavor, or toss in some olives for that briny element that feta provides.

How to Make Marinated Vegetarian Pasta Salad

Step 1: Prepare the Dressing

Combine lemon juice, olive oil, sugar, minced garlic, salt, pepper, dried herbs, and chili flakes in a jar. Shake vigorously until emulsified, then set aside for at least 10 minutes to let the flavors marry.

Step 2: Roast the Vegetables

Preheat your oven to a scorching 250°C/480°F. Toss all vegetables (except asparagus) with olive oil, salt, pepper, and minced garlic. Spread them across two baking sheets, giving them plenty of room to roast rather than steam. Roast for 25 minutes, stirring once halfway through.

Step 3: Add the Asparagus

In the last 5 minutes of roasting, add the asparagus (drizzled with a bit of oil and seasoned) to the oven. This prevents it from overcooking and turning mushy.

Step 4: Marinate the Vegetables

Transfer the hot roasted vegetables to a large bowl and immediately pour over half the dressing. Toss gently and let them soak up all that flavor for at least 30 minutes. This step is crucial—don’t rush it!

Step 5: Cook the Pasta

Boil the pasta for 2 minutes longer than the package instructions. This extra cooking time ensures the pasta stays tender even when cold. Drain and return to the pot.

Step 6: Combine and Rest

Add the marinated vegetables (with all their flavorful juices) to the pasta, along with the remaining dressing and fresh parsley. Toss thoroughly and let it rest for about 15 minutes to cool slightly and allow the pasta to absorb some of the dressing.

Step 7: Finish and Serve

Just before serving, gently fold in the crumbled feta. Enjoy at room temperature for the best flavor.

Pro Tips for Making the Recipe

Overcook the Pasta (Intentionally): Cooking pasta 2 minutes longer than al dente ensures it won’t become unpleasantly firm when cold.
High Heat Is Your Friend: Roasting at a very high temperature gives you those beautiful caramelized edges without turning the vegetables to mush.
Don’t Crowd the Roasting Pans: Give your vegetables space to roast properly—if they’re crowded, they’ll steam instead of caramelize.
Save That Pasta Water: Before draining the pasta, save some of the starchy cooking water to revive leftover pasta salad later.
Layer Your Flavors: Using both raw and roasted garlic creates a more complex flavor profile.
Let It Rest: The pasta salad needs time to absorb the dressing and for the flavors to develop. Patience pays off here!

How to Serve

Main Dish Serving

Serve a generous portion alongside a simple green salad and perhaps some crusty bread to soak up any extra dressing.

Side Dish Pairings

This pasta salad is perfect alongside grilled foods—try it with veggie burgers, grilled halloumi, or even simple grilled vegetables for a double dose of plant-based goodness.

Picnic Perfect

Pack it up for a picnic or potluck—it travels well and doesn’t need refrigeration for a few hours.

Temperature Matters

This salad is at its absolute best served at room temperature, not cold from the refrigerator.

Make Ahead and Storage

Storing Leftovers

Store in an airtight container in the refrigerator for up to 5 days. The flavor actually improves after a day or two!

Freshen Up Leftovers

When serving leftover pasta salad, bring it to room temperature first. Toss with a little reserved dressing (made with pasta water per the pro tip) to revive its juiciness. A fresh squeeze of lemon can also brighten it back up.

Freezing

This pasta salad isn’t suitable for freezing, as the vegetables will become mushy and the texture will suffer significantly.

Reheating

No need to reheat! This is designed to be enjoyed at room temperature. If you’ve refrigerated it, simply let it sit out for 30 minutes before serving.
