Ingredients You’ll Need
- 12 ounces spaghetti, broken in half
- 1 cup cherry tomatoes, halved
- 1 cucumber, diced
- 1 red bell pepper, chopped
- 1 green bell pepper, chopped
- 1/2 red onion, finely sliced
- 1 (2.25-ounce) can sliced black olives, drained
- 1/2 cup grated Parmesan cheese
- 1 cup Italian dressing (store-bought or homemade)
- 1 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt (adjust to taste)
Step-by-Step Instructions
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil. Add the spaghetti (broken in half) and cook according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process and cool the pasta completely.
Step 2: Prepare the Vegetables
While the pasta is cooking, chop all the vegetables. Slice the tomatoes, dice the cucumber, chop the bell peppers, and thinly slice the red onion.
Step 3: Combine Ingredients
In a large mixing bowl, add the cooled spaghetti, chopped vegetables, black olives, and Parmesan cheese.
Step 4: Add the Dressing
Pour the Italian dressing over the mixture. Sprinkle in garlic powder, black pepper, and salt. Toss everything together until evenly coated.
Step 5: Chill
Cover the bowl and refrigerate for at least 2 hours before serving. This allows the flavors to fully develop and blend together.
Step 6: Serve
Give the salad a quick toss before serving. Adjust seasoning if needed and enjoy chilled.
Tips for Best Results
For the best texture, avoid overcooking the spaghetti. It should be slightly firm (al dente) so it holds up well after chilling.
Rinsing the pasta with cold water is important—it stops cooking and prevents sticking.
Letting the salad rest in the fridge enhances the flavor, so don’t skip the chilling step.
If the pasta absorbs too much dressing after chilling, simply add a little more before serving.
Delicious Variations
Add grilled chicken, shrimp, or tuna for a protein boost and turn this side dish into a complete meal.
For a vegetarian twist, include chickpeas or cubed mozzarella for added texture and flavor.
If you like a bit of heat, toss in some crushed red pepper flakes or diced jalapeños.
Substitutions You Can Try
You can use whole wheat or gluten-free spaghetti depending on your dietary preference.
Greek dressing can replace Italian dressing for a slightly different flavor profile.
Swap Parmesan with feta cheese for a tangier taste.
Serving Suggestions
This California spaghetti salad pairs perfectly with grilled meats, burgers, or sandwiches. It’s also an excellent addition to potlucks and picnics.
Serve it alongside fresh fruit or a light soup for a balanced meal.
Storage Instructions
Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
Before serving again, stir well and refresh with a bit of extra dressing if needed.
