Ingredients You’ll Need

In this recipe, sautéed veggies are tossed with pasta for a quick, healthy meal. Here’s everything you’ll need, plus a few ideas on substitutions:

  • Mushrooms – I used baby bellas here. Feel free to use your favorite variety. Pre-sliced is great for convenience.
  • Zucchini + Yellow squash – If you only have one type of squash available, use two.
  • Onion – Any color will do.
  • Garlic – If you don’t have fresh on hand, use 1 teaspoon garlic powder.
  • Tomatoes – We’ll be using canned diced tomatoes with juices for ease.
  • Spinach – Swap with baby kale, chard, or any combo.
  • Red pepper flakes – Because a little heat is always welcome!
  • Oregano – Use dried or fresh. Swap with an Italian seasoning. In addition, toss in fresh basil or parsley at the end of cooking for an added punch of flavor.
  • Mineral salt & cracked pepper
  • Olive oil – Use your favorite neutral-flavored oil. For an oil-free option, substitute with water or broth.
  • Pasta – You can use spaghetti, linguine, or your favorite pasta. Regular, whole wheat, or gluten-free pasta all work.

Nothing fancy, just super simple ingredients that taste great together!

How To Make The Best Vegetable Spaghetti

You’ll love how easy this veggie spaghetti recipe is!

  • Simply cook your pasta of choice according to package directions.
  • In a large skillet, heat oil over medium-high. Add mushrooms, zucchini, onion, garlic, and spices, and cook for about 10 minutes, or until mushrooms and zucchini are tender. The mushrooms and zucchini will sweat down for plenty of flavorful juices.
  • Stir in tomatoes and cook until heated through; add spinach at the end and taste for seasoning.
  • Serve veggies and juices over a bed of pasta with a good dusting of almond parmesan.

And that’s it: quick, healthy, and delicious!

Ingredient Swaps & Variations

Here are a few great ideas for swapping or adding additional ingredients:

  • Bell peppers (red/yellow for sweetness and color)
  • Carrots (thinly sliced for quick cooking)
  • Broccoli florets (add with zucchini for crunch)
  • Eggplant (diced small for heartiness)
  • Add protein: Toss in chickpeas, white beans, or vegan sausage slices for extra filling power.
  • For creamier texture: Blend a portion of the cooked veggies with a bit of pasta water for a silky sauce.
  • Add tomato paste: Stir in 1 Tablespoon while sautéing the veggies and garlic. It caramelizes slightly, adding umami and a deeper tomato flavor.

Serving Suggestions

We love this veggie-filled spaghetti on its own, but it can be enhanced with any of these options:

How Long Do Leftovers Keep?

Leftovers can be stored in the refrigerator for 4 – 5 days in a covered container. It’s also great for meal prep using these multi-use glass containers (affiliate link).

I dub this the ‘lazy pasta’, because some days you just want a hearty, quick meal. This easy vegetable spaghetti recipe uses simple, everyday ingredients and is ready in about 20 minutes! Includes an oil-free option.

  • Author: Julie | The Simple Veganista
  • Prep Time: 10 min
  • Cook Time: 10 min
  • Total Time: 20 minutes
  • Yield: Serves 3
  • Category: Entree, Pasta
  • Method: boil, saute
  • Cuisine: Vegan

Ingredients

Scale
  • 1 tablespoon olive oil (or 3 tablespoons water/broth)
  • 1 onion, thinly sliced
  • 23 garlic cloves, minced
  • 8 oz. mushrooms, sliced (I used baby bella)
  • 1 medium zucchini, thinly sliced and cut in half
  • 1 medium yellow squash, thinly sliced and cut in half
  • 1 can (28 oz.) diced tomatoes, with juices
  • 1 teaspoon dried oregano
  • 1/2 teaspoon red pepper flakes
  • mineral salt & cracked pepper to taste
  • 2 handfuls of spinach, or baby greens of choice
  • 8 oz. pasta of choice (I used quinoa linguini pasta)
  • almond parmesan, to serve

Instructions

Pasta: Cook your pasta of choice according to package directions. Set aside.

Vegetables: In a large flat-bottom pan, heat oil over medium-high heat. Add mushrooms, zucchini, onion, garlic, and spices, cook for about 8 – 10 minutes, or until mushrooms and zucchini are tender, stirring frequently. Add tomatoes and cook until heated through. Stir in spinach and let it wilt. Taste for seasoning.

Assemble: Serve veggies over a bed of pasta with a good dusting of almond parmesan.

Serves 3

Store: Leftovers can be kept in the refrigerator for 5- 6 days in a covered container.

Notes

If you prefer, saute the onions and garlic for 5 minutes, then add the other ingredients and saute again until tender. That is how it is usually done in recipes, but this is a ‘lazy pasta,’ and I cut that part out with great results, at least I think it was fine!

Don’t overcook veggies: Aim for tender but still vibrant—zucchini and mushrooms release great juices without turning mushy.

More topping ideas: Sprinkle with nutritional yeast for a cheesy umami kick (vegan-friendly), toasted pine nuts or breadcrumbs for crunch, or a drizzle of good olive oil. Add herbaceousness with a sprinkle of chopped parsley and red pepper flakes.

Add tomato paste: Stir in 1-2 tablespoons when sautéing the veggies and garlic. It caramelizes slightly, adding rich umami and a deeper tomato flavor.

Add protein: Toss in chickpeas, white beans, or vegan sausage slices for extra filling power.

For creamier texture: Blend a portion of the cooked veggies with a bit of pasta water for a silky sauce variation.

  1. really enjoyed this, I used some yellow and red peppers instead of yellow squash. Plus added 1 tsp of dried basil. A good refreshing taste of fresh veggies, Will definitely make this again. Thanks

  2. How can I get protein in this meal?

    1. Julie | The Simple Veganista says:

      Great question, Dawn! This would be great with some sliced vegan Italian sausage such as Field Roast or Tofurky. You could also try adding a can of drained and rinsed white beans such as cannellini, great northern, or chickpeas with the veggies while they cook. You might also try using a protein rich pasta. There are protein fortified pastas or bean/legume pastas that will help boost the protein profile pretty sufficiently. Any of the ideas should help. Enjoy!

  3. Very good food. Can it freeze?

    1. Julie | The Simple Veganista says:

      Yes, you can freeze this recipe. Enjoy!

  4. Left out a few things only because I wasn’t paying attention but it was soooo good! Super quick and easy on a work night. It’s a keeper!!
