  • Olive oil (4 tbsp): For richness and to sauté the veggies.
  • Chopped onion (1 cup / 140g): The base of flavor for any good sauce.
  • Zucchini (2 medium) & Yellow squash (2 medium): Mild, tender, and full of moisture—these soak up all the sauce’s flavor.
  • Garlic (3 cloves): For that unmistakable Italian aroma.
  • Dried oregano (½ tsp) & red pepper flakes (¼ tsp): Herbs and a little heat to liven things up.
  • Tomato paste (2 tbsp): For depth and a touch of sweetness.

  • Roasted red peppers (12oz jar, about 1 cup): Sweet, smoky, and so colorful.
  • Mushroom powder (2-3 tsp, optional): A flavor booster for umami; skip if you like, but it takes the sauce up a notch!
  • Spinach leaves (5 cups / 226g): Add these at the end for a pop of green and gentle earthiness.
  • Fresh basil (handful): Classic Italian flavor—don’t skip!
  • Salt & pepper: Essential for taste.
  • Parmesan cheese or nutritional yeast: For that final hit of savoriness (use nutritional yeast for a vegan version).

Step-by-Step: How to Make Easy Veggie Spaghetti

1. Make the Vegetable Pasta Sauce

Sauté the onions:
Heat the olive oil in a large, wide skillet over medium heat. Add the onion and cook, stirring now and then, until soft and translucent—about 3–5 minutes. This slow start lets the onions release their sweetness.

Add zucchini, yellow squash, garlic, herbs, and seasoning:
Toss in the chopped zucchini, yellow squash, minced garlic, dried oregano, red pepper flakes, and a pinch of salt. Sauté, stirring occasionally, for 5–8 minutes. The veggies should be tender but still vibrant and a little crisp—they’ll finish cooking in the sauce.

Tomato paste magic:
Stir in the tomato paste and cook another minute to caramelize it slightly. This builds a deeper, richer sauce.

Bring on the tomatoes and roasted peppers:
Add the roasted red peppers, whole peeled tomatoes (with juice), and mushroom powder if using. Use a spoon to break up the whole tomatoes a bit for a rustic, chunky texture.

Simmer:
Bring the sauce to a low simmer. Cook, uncovered, for about 10 minutes, stirring occasionally, until the liquid thickens and reduces by half. The sauce should cling beautifully to the pasta when it’s done.

2. Cook the Pasta

While the sauce is simmering, boil a large pot of salted water. Cook the spaghetti (or your pasta of choice) until just al dente, following package directions. Reserve a little cooking water, then drain the pasta.

3. Wilt the Greens and Finish the Sauce

Take the sauce off the heat. Add the spinach and fresh basil, stirring until the spinach just wilts and the basil perfumes the whole dish. Taste and season with extra salt and pepper as needed.

4. Bring It All Together

Add the hot, drained pasta to the sauce in the skillet. Toss well so every strand is coated and the pasta absorbs some of that fresh vegetable flavor. Let it rest a minute, toss again, and you’re ready to serve.

Pro Tip: If the sauce seems thick, loosen it with a splash of reserved pasta water for a silky, glossy finish.

Tips, Swaps & Variations

  • Swap in veggies: Eggplant, bell peppers, mushrooms, cherry tomatoes, or kale all work well.
  • Make it vegan: Use nutritional yeast instead of Parmesan.
  • Boost protein: Add cooked white beans, lentils, or grilled tofu.
  • Make it spicy: Increase red pepper flakes or add fresh chili.
  • Gluten-free: Use GF pasta.

Serving Suggestions

  • Toppings: Finish each plate with extra basil, black pepper, and lots of freshly grated Parmesan or nutritional yeast.
  • With bread: Serve with warm, crusty bread or garlic toast to mop up extra sauce.
  • On the side: Try a simple green salad with balsamic vinaigrette for balance.
