Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water (1 tbsp salt) to a boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente. Reserve 1/2 cup pasta water and drain.
  2. Step 2: While pasta cooks, heat 3 tbsp olive oil in a large skillet over medium heat. Add 2 minced garlic cloves and sauté for 30 seconds until fragrant.
  3. Step 3: Add 1 medium diced zucchini, 1 cup halved cherry tomatoes, and 1 diced red bell pepper to the skillet. Cook for 5-6 minutes until vegetables are tender but still vibrant.
  4. Step 4: Add cooked spaghetti to the skillet with vegetables. Stir in 1/2 cup basil pesto and 1/4 cup grated Parmesan cheese. Toss to combine, adding reserved pasta water a few tablespoons at a time to loosen sauce.
  5. Step 5: Season with 1/2 tsp black pepper and 1/2 tsp salt to taste. Serve immediately with extra Parmesan if desired.

How do I store leftover Spaghetti with Seasonal Vegetable Medley and Basil Pesto?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Spaghetti with Seasonal Vegetable Medley and Basil Pesto?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Spaghetti with Seasonal Vegetable Medley and Basil Pesto for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
