How to Make Vegetarian Pasta Salad

Making the Vinaigrette

Gather your ingredients. The aroma of garlic and oregano will fill your kitchen as you whisk the vinaigrette. Make the vinaigrette first. Whisk together the olive oil, red wine vinegar, Dijon, oregano, minced garlic, salt, and pepper. Set the dressing aside.

Cooking the Pasta

Cook the bowtie pasta according to the package directions (boil 7-10 minutes or until tender), then drain in a colander. Cook the pasta al dente – it should be firm to the bite. Rinse briefly to cool the pasta, then let it drain well. The pasta should be well-drained and not dripping wet before adding it to the vegetables.

Prepping the Vegetables

While the pasta is cooking and draining, prepare the vegetables. Thinly slice the red onion and marinate it in the red wine vinegar for 15-20 minutes. This is our flavor secret! Chop the tomatoes, squash, zucchini, broccoli, and parsley. Slice the roasted red peppers (drained).

Combining and Serving

Place the pasta and chopped vegetables in the largest bowl you have. Give the vinaigrette a brief whisk, then pour it over the salad. Stir the pasta and vegetables until everything is coated in dressing. Give it a taste and add salt or pepper, if needed. Serve immediately, or refrigerate until ready to eat.

Choosing the Best Pasta for Pasta Salad

Bowtie, rotini, and penne are some of the best choices for a vegetarian pasta salad. The shape of the pasta is important for holding the dressing and other ingredients.

Bowtie pasta is a classic choice because of its unique shape. Rotini is great because its spirals hold the dressing well. Penne’s ridges and cylindrical shape also make it ideal.

Cooking the pasta perfectly is key. Cook it al dente to avoid mushiness. Rinsing the pasta cools it and removes excess starch, preventing stickiness. Adding a little oil or cooking in salted water also helps.
