Prep Time: 15 minutes

Cook Time: 20 minutes

Total Time: 35 minutes

Yield: 4 servings

Ingredients

  • 1 tablespoon olive oil
  • 1 small yellow onion, diced
  • 3 cloves garlic, minced
  • 1 teaspoon dried oregano
  • ½ teaspoon red pepper flakes (optional, for a touch of heat)
  • 1 medium zucchini, halved lengthwise and sliced into ¼-inch moons
  • 1 pint cherry tomatoes, halved
  • 1 (14.5 ounce) can diced tomatoes, undrained
  • 4 cups vegetable broth
  • 8 ounces linguine or spaghetti, broken in half
  • ½ cup fresh basil leaves, chopped, plus more for garnish
  • Salt and freshly ground black pepper to taste
  • Optional: 2 tablespoons nutritional yeast, for a cheesy flavor

Step-by-Step Instructions

  1. Sauté Aromatics: Heat the olive oil in a large, deep pot or Dutch oven over medium heat. Add the diced yellow onion and cook, stirring occasionally, until softened and translucent, about 5-7 minutes.
  2. Add Garlic and Spices: Stir in the minced garlic, dried oregano, and red pepper flakes (if using). Cook for another minute until fragrant, being careful not to burn the garlic.
  3. Combine Vegetables and Liquids: Add the sliced zucchini, halved cherry tomatoes, canned diced tomatoes (undrained), and vegetable broth to the pot. Stir gently to combine all ingredients.
  4. Introduce Pasta: Carefully add the broken linguine or spaghetti to the pot, submerging it as much as possible in the liquid.
  5. Cook the Pasta: Bring the mixture to a boil, then reduce the heat to medium-low, cover the pot, and simmer for 15-20 minutes, or until the pasta is al dente and most of the liquid has been absorbed. Stir frequently (every 2-3 minutes) to prevent the pasta from sticking to the bottom of the pot and to ensure even cooking.
  6. Finish and Season: Once the pasta is cooked to your desired tenderness and the sauce has thickened, remove the pot from the heat. Stir in the fresh chopped basil and nutritional yeast (if using). Season generously with salt and freshly ground black pepper to taste.
  7. Serve: Ladle the pasta into bowls, garnish with extra fresh basil, and serve immediately.

Pro Tips for Success

  • Choose Your Broth Wisely: The quality of your vegetable broth significantly impacts the final flavor. Opt for a good quality, low-sodium vegetable broth for the best results, allowing you to control the seasoning.
  • Stir, Stir, Stir: This is crucial for one-pot pasta! Stirring frequently, especially during the first 5-7 minutes of cooking, prevents the pasta from clumping together and sticking to the bottom of the pot. It also helps the pasta release its starches, contributing to a creamy sauce.
  • Adjust Liquid as Needed: Different pasta shapes and brands can absorb liquid at varying rates. If your pasta looks too dry before it’s fully cooked, add a splash more vegetable broth or water. If it’s too soupy, let it simmer uncovered for a few extra minutes to reduce.
  • Don’t Overcook the Zucchini: Zucchini cooks quickly. By adding it at the beginning with the other liquids, it will become tender but still retain a slight bite, avoiding a mushy texture.

Variations & Substitutions

  • Gluten-Free Option: Easily make this recipe gluten-free by using your favorite gluten-free pasta. Be aware that cooking times might vary slightly, so keep an eye on it.
  • Higher Protein Boost: For a more substantial meal, stir in a can of drained and rinsed chickpeas or cannellini beans along with the zucchini and tomatoes.
  • Add More Greens: Wilt in a few handfuls of fresh spinach or chopped kale during the last 5 minutes of cooking for an extra boost of nutrients.
  • Spicy Kick: If you love heat, increase the red pepper flakes to 1 teaspoon or add a dash of your favorite hot sauce at the end.
  • Creamy Texture: For a richer, creamier sauce, stir in 2-3 tablespoons of vegan cream cheese or a splash of full-fat coconut milk (from a can) at the very end.
  • Other Summer Veggies: Feel free to swap or add other quick-cooking summer vegetables like corn kernels, bell peppers, or green beans.

Serving Suggestions

This One-Pot Summer Vegetable Pasta is a complete meal on its own, but it pairs beautifully with a simple side salad dressed with a light vinaigrette. A slice of warm, crusty bread or garlic bread is also perfect for soaking up any leftover sauce. It’s an ideal dish for a relaxed weeknight dinner, a quick and satisfying lunch, or even a casual potluck.

Storage & Reheating

Fridge: Store any leftover pasta in an airtight container in the refrigerator for up to 3-4 days. The pasta will continue to absorb liquid, so the texture may change slightly.

Freezer: Freezing is not recommended for this dish, as pasta can become mushy and the vegetables lose their texture upon thawing.

Reheating: To reheat, gently warm the pasta in a saucepan over medium-low heat, adding a splash of vegetable broth or water to loosen the sauce and rehydrate the pasta. You can also microwave individual portions, stirring halfway through.

Frequently Asked Questions

Q: Can I use other types of pasta?
A: Yes, absolutely! While linguine or spaghetti works well, you can use other long or short pasta shapes like penne, rotini, or fettuccine. Just be aware that cooking times might vary slightly, so monitor the pasta for doneness.

Q: How can I make this dish creamier?
A: To achieve a creamier texture, you can stir in 2-3 tablespoons of vegan cream cheese, a splash of full-fat coconut milk (from a can), or a tablespoon of cashew cream at the very end of cooking, after removing it from the heat.

Q: My pasta is sticking to the bottom of the pot, what should I do?
A: This is a common issue with one-pot pasta. Ensure you are stirring frequently, especially during the first few minutes of cooking, to prevent sticking. Using a wider pot or Dutch oven can also help by providing more surface area for the pasta to cook without clumping.
