Best Zucchini Noodle Spaghetti Recipe

If you ask me, zucchini noodles are one of the best kitchen discoveries ever.

This fresh take on traditional spaghetti swaps regular pasta for spiralized zucchini, creating a lighter dish that still delivers all the comfort of the classic version. The tender zucchini noodles pair perfectly with your favorite marinara sauce and Italian seasonings.

It’s topped with just the right amount of Parmesan cheese and fresh basil, making each forkful taste like something you’d get at your neighborhood Italian restaurant. Plus, it’s a great way to sneak extra vegetables onto your plate.

It’s a feel-good dish that comes together in minutes, perfect for those busy weeknight dinners when you want something quick but satisfying.

What Kind of Zucchini Should I Use?

For making zucchini noodles (often called “zoodles”), medium-sized zucchini around 6-8 inches long work best. These are easier to spiralize and tend to have fewer seeds than larger ones, which can get watery and mushy. Look for firm, dark green zucchini without any soft spots or blemishes. While both regular green and yellow summer squash can work for this recipe, traditional green zucchini holds its shape better when cooked. Just remember to avoid the giant zucchini from your garden – those tend to be too seedy and watery for making good noodles.

Options for Substitutions

This healthy twist on classic spaghetti offers plenty of room for substitutions:

• Minced beef: You can easily swap the beef for ground turkey, chicken, or even plant-based alternatives like Beyond Meat. For a vegetarian version, try using crumbled mushrooms or lentils – just cook them until they’re nice and dry.
• Zucchini noodles: Not a fan of zucchini? Try using other veggie noodles like butternut squash, sweet potato, or carrot spirals. Just remember that harder vegetables might need a bit more cooking time than zucchini.
• Canned tomatoes: Fresh tomatoes work too – use about 4 medium tomatoes, chopped, in place of the canned whole ones. For tomato sauce, you can blend fresh tomatoes until smooth. In a pinch, passata makes a good substitute.
• Dried herbs: Feel free to use fresh herbs instead – triple the amount called for dried ones. Italian seasoning can replace the individual herbs if that’s what you have on hand.
• Tomato paste: If you’re out of tomato paste, you can cook down extra tomato sauce until it thickens, or use sun-dried tomato puree for a different but tasty twist.

Watch Out for These Mistakes While Cooking

The biggest challenge when making zucchini noodles is dealing with excess moisture – to avoid a watery sauce, make sure to salt your spiralized zucchini and let them sit in a colander for 15-20 minutes, then pat them dry with paper towels before cooking. When cooking the zucchini noodles, resist the urge to overcook them – 2-3 minutes in the pan is plenty, as they’ll continue cooking from residual heat and you want to maintain some crunch to prevent mushiness. For the meat sauce, don’t rush the simmering process – giving it at least 20-30 minutes allows the flavors to develop properly and the sauce to thicken naturally. A helpful tip is to cook your sauce separately from the zucchini noodles and only combine them right before serving to prevent the noodles from releasing more water into your perfectly seasoned sauce.

What to Serve With Zucchini Noodle Spaghetti?

Since zucchini noodles are a lighter take on traditional pasta, you’ve got lots of room to play with sides! A warm piece of crusty garlic bread or cheesy breadsticks are perfect for soaking up the tasty meat sauce. For a complete low-carb meal, try adding a fresh Caesar salad or some roasted Brussels sprouts on the side. If you’re feeding a bigger crowd, Italian-style meatballs make a great addition to this dish, and you can never go wrong with a sprinkle of extra Parmesan cheese on top!

Storage Instructions

Keep Fresh: The meat sauce and zucchini noodles are best stored separately to keep the zoodles from getting mushy. Place the cooled meat sauce in an airtight container in the fridge for up to 4 days. For the raw zucchini noodles, wrap them in paper towels and store in a container – they’ll stay good for 2-3 days.

Freeze: The meat sauce freezes really well! Let it cool completely, then pop it into freezer-safe containers or bags – it’ll keep for up to 3 months. I don’t recommend freezing the zucchini noodles though, as they tend to get pretty watery when thawed.

Prep Ahead: You can make the meat sauce ahead of time and spiralize your zucchini a day before. When you’re ready to eat, just warm up the sauce and toss it with your fresh zoodles. This makes weeknight dinners super quick and easy!

Ingredients

For the sauce:

• 1 can tomato paste
• 1 lb ground beef
• 1/4 tsp red chili flakes (for a subtle kick)
• 1/2 tsp dried oregano
• 1 tsp black pepper
• 1 can whole peeled tomatoes (crushed by hand for texture)
• 1/2 tsp onion powder
• 1/2 tsp garlic powder
• 1 tsp dried basil (for classic Italian flavor)
• 1 tbsp salt
• 1 can tomato sauce (I use Muir Glen organic tomato sauce)
• 1/4 tsp ground thyme

For the noodles:

• 3 zucchini (sliced into long, thin strips using a spiralizer or mandoline)

Step 1: Brown the Ground Beef

Start by heating a large skillet over medium-high heat.

Add the ground beef and a dash of black pepper to the hot skillet.

Cook and stir the beef until it is browned and crumbly, which should take about 5 to 7 minutes.

Once the beef is cooked, drain and discard any excess grease to reduce fat content.

Step 2: Prepare and Heat the Sauce

With the browned beef still in the skillet, stir in the tomato sauce and diced tomatoes.

Add salt, basil, oregano, garlic powder, onion powder, thyme, and red pepper flakes.

Continue to cook and stir this mixture until the sauce is thoroughly warmed, about 2 minutes.

To thicken the sauce, incorporate a dollop of tomato paste, stirring well until it is fully integrated.

Step 3: Incorporate Zucchini Noodles

Gently mix the zucchini “noodles” into the sauce, ensuring they are fully submerged.

This helps the flavors meld together.

Lower the heat to medium-low and let the mixture simmer, allowing the zucchini to become tender over the next 10 minutes.

Stir occasionally to ensure even cooking.

Once the zucchini noodles are cooked to your preference, the dish is ready to serve.
