Pasta Salad Ingredients

All the ingredients gathered for making a vegan southwest pasta salad with bell pepper, red onion, jalapeno and cashew sauce. Each ingredient is labelled with text.

A complete list of ingredients with amounts and full instructions is located in the printable recipe card below. This section covers ingredient and substitution considerations.

  • Pasta: This recipe calls for about 375 g of rotini pasta. However, you can substitute it for your favourite kind, including gluten-free or whole wheat varieties. Small pasta shapes like bows, mini shells, macaroni, fusilli and penne work best.
  • Black Beans: Canned black beans work or you can use chickpeas, kidney beans or pinto beans. I like black beans best for this recipe though.
  • Corn kernels: Use fresh, thawed and drained frozen, or canned corn, depending on what’s available to you. Fresh is best during the late summer months when corn is in season!
  • Olive oil: You’ll need 2 tsp to roast the corn. Avocado oil and canola oil are good substitutes. It’s best not to omit the oil since it prevents the corn from drying out!
  • Smoked Paprika: If you don’t have smoked paprika you can add regular paprika but the smoked paprika does add a nice hint of smoky flavour to the salad.
  • Chipotle Powder: If you don’t have the chipotle powder you can use 1 chipotle pepper in adobo sauce or 2-3 tsp of the adobo sauce from the can.
  • Other Spices: You’ll need cumin, salt and pepper. Feel free to adjust these as necessary to your preference. If you’d like a little more heat you can add a pinch of cayenne pepper or red pepper flakes.
  • Roasted cashews: You can use roasted or raw cashews for the dressing but roasted cashews add a nice layer of flavour. We’ll cover some options for making this recipe nut-free below.
  • Garlic: A fresh clove of garlic is best but you can use 1 tsp of garlic powder as a substitute if that’s what you have.
  • Tomato: You can use grape tomato, cherry tomato or Roma tomato.
  • Bell Peppers: The recipe calls for red bell pepper but you can use any colour of bell pepper such as green or yellow bell pepper.
  • Jalapeno: Be sure to de-seed the jalapeno and wash well (and wash hands well after handling!). Poblano pepper would work as a substitute.
  • Cilantro: Skip it if you’re not a fan!
  • Limes: You’ll need 2-3 fresh limes to make the lime juice and lime zest.

How To Make Southwest Pasta Salad

Before You Start: Place the cashews in a bowl and cover with 1 cup of boiling water. Soak them for at least 15 minutes or until the water is cool. You can leave them up to 8 hours so this can be done in advance.

Step 1: Cook Your Pasta

In a large pot of salted boiling water, cook your pasta according to package instructions. Once cooked, drain and rinse well under cold water. This will stop the cooking and help prevent the pasta from sticking together once cooled.

Step 2: Roast the Corn & Jalapeno

While the pasta is cooking, mix together the corn kernels, diced jalapeno, and olive oil in a medium-sized bowl (or just mix on the baking tray). Place this mixture evenly on a baking sheet and roast in the oven on broil for 2 minutes.

Give it a stir and then place it back in the oven for an additional 2 minutes or until the corn is golden brown. Remove it from the oven and let cool.

Step 3: Make The Chipotle Dressing

Once the cashews have soaked, add the cashews and water to a blender along with the spices, garlic, lime juice, and zest. Blend until completely smooth.

If needed, you may need a little water to adjust the consistency. It should be thick and creamy but able to be poured from the blender.

Quick Tip: When preparing the lime zest, make sure you’re using the green peel only and not the bitter white pith underneath. A citrus zester works best for this!

Step 4: Combine the Pasta, Veggies & Dressing

Once the pasta is cooked and the corn has cooled, place it all in a large bowl with the onion, peppers, cherry tomatoes, and black beans. Pour in your dressing and mix thoroughly.

You can serve it immediately, but like many pasta salads, it’s best to let it sit in the fridge for at least an hour. That way, all the flavours really come together!

Season with additional salt and pepper, if needed, and serve your pasta salad topped with cilantro and fresh lime wedges on the side.

Quick Tip: If you’re not serving the salad right away, consider adding half of the dressing now and reserving the other half for just before serving. The pasta soaks up the sauce as it sits so the salad will dry out a bit over time.

Notes & Tips

  1. Timing: Start a pot of boiling water for the pasta and get the cashews soaking right away. While you wait, chop up the fresh ingredients so you’re ready to go.
  2. Serving Size: This recipe can easily be cut in half or doubled as needed.
  3. No-Cook: You can skip the roasted corn and just fresh, canned or thawed frozen to make this even easier with cooking involved.
  4. Spiciness: For more heat, add up to 1/2 tsp cayenne or red chili flakes. You can also add more chipotle powder or 1-2 chipotle pepper in adobo sauce.

FAQs

Storing & Making Ahead

  • If you’re not serving the salad right away, consider adding half of the dressing and reserving half for just before serving. The pasta continues to soak up the sauce so the salad will dry out a bit after storing.
  • Fridge: Keep it in the fridge for up to 4-5 days. Use a sealed container.
  • Freezing: This recipe is not suitable for freezing.
  • Making Ahead: You can make the whole salad ahead of time or do a partial prep to speed things up by chopping up the veggies and make the dressing a day ahead of time. If the dressing is very thick after storing, you can thin it out with a little water.
