Why You'll Love this Zucchini Noodle Spaghetti:
Light but satisfying: Zucchini noodles provide a fresh base that still pairs perfectly with a classic tomato sauce.
Quick weeknight dinner: Ready in about 25 minutes with minimal prep and simple ingredients.
Simple, familiar flavors: Garlic, herbs, and basil create a sauce that tastes like traditional spaghetti.
Vegetable-forward: A great way to enjoy more vegetables without sacrificing comfort-food appeal.
Easy to customize: Add protein, extra veggies, or cheese to make it your own.
Key Ingredients:
- zucchini. Medium-sized zucchini work best for even, sturdy noodles. Avoid overripe zucchini, as they contain more water and can become mushy.
- crushed tomatoes. A 14.5 oz can of crushed tomatoes provides a smooth base for the marinara sauce. If you prefer a chunkier texture, use diced tomatoes instead.
- seasonings. Dried oregano and basil are classic Italian herbs give the sauce its signature flavor. You can substitute with Italian seasoning if needed. Red pepper flakes add a subtle heat.

Easy Substitutions & Variations:
- Add protein: Top with grilled chicken, sautéed shrimp, turkey meatballs, or Italian sausage.
- Sauce swap: Use marinara, arrabbiata, or a roasted tomato sauce instead of crushed tomatoes.
- Cheese options: Parmesan, pecorino romano, or dairy-free cheese alternatives all work well.
- Extra vegetables: Stir in mushrooms, spinach, bell peppers, or olives for more texture and flavor.
- Spice level: Increase or omit the red pepper flakes to adjust heat.

How to Make Zucchini Noodle Spaghetti:
- Spiralize the zucchini into noodles using a spiralizer. If you don't have a spiralizer, you can use a julienne peeler or vegetable peeler to create thin ribbons.
- In a large pan over medium heat, add olive oil, then sauté the diced onion until softened, about 4-5 minutes.
- Add the minced garlic and cook for another minute until fragrant.
- Stir in the crushed tomatoes, dried oregano, dried basil, and red pepper flakes. Season with salt and pepper to taste. Let the sauce simmer for 10-15 minutes to allow the flavors to meld.
- While the sauce is simmering, heat a separate large pan over medium heat. Add the zucchini noodles and sauté them for 2-3 minutes, just until tender but still slightly crisp. Be careful not to overcook them as they can become soggy.
- Plate the zucchini noodles and top with the marinara sauce. Sprinkle with fresh basil and grated Parmesan cheese.
Recipe Notes & Tips:
- Avoid watery noodles: Lightly sauté zucchini noodles for just 2-3 minutes and avoid overcrowding the pan.
- Salt at the end: Salting zucchini early draws out moisture; season after cooking for the best texture.
- Simmer the sauce separately: Letting the sauce thicken before adding the noodles keeps the dish from becoming watery.
- Serve immediately: Zucchini noodle spaghetti is best enjoyed fresh while the noodles are tender-crisp.
- Use fresh basil last: Stir in basil just before serving to preserve its flavor and color.
- Serving Suggestions: We love serving these zucchini noodles with Chicken Meatballs, Wedge Salad and Gluten-Free Focaccia.

How to Store:
Refrigeration: Store leftover zucchini noodles and sauce separately in airtight containers. The noodles stay fresh for 2-3 days, while the sauce lasts up to 5 days in the refrigerator.
Reheating: Warm the sauce on the stovetop over medium heat. Reheat the zucchini noodles in a dry pan for 1-2 minutes to avoid excess moisture.
Freezing: The marinara sauce freezes well for up to 3 months in a freezer-safe container. However, zucchini noodles do not freeze well due to their high water content. If meal prepping, spiralize fresh zucchini before freezing and cook when ready to serve.
Zucchini Noodle Spaghetti FAQs:
Zucchini noodle spaghetti stays firm when the noodles are cooked briefly over medium heat and not salted until the end. Overcooking or salting too early releases excess moisture and can thin the sauce.
Yes, zucchini noodles are best cooked separately and topped with sauce just before serving. This prevents the noodles from releasing water into the sauce and keeps zucchini noodle spaghetti from becoming soggy.
A thicker tomato sauce works best for zucchini noodle spaghetti because it coats the noodles without pooling liquid. Simmering the sauce until reduced helps maintain the right texture.
