What Are Zoodles? 

If you haven’t jumped on the zoodles bandwagon yet, now is the time! Given a fun name, zoodles are just zucchini that have been sliced or spiralized to resemble the shape of spaghetti noodles

Health Benefits

A great low carb option, zoodles are bursting with nutrition and health benefits! For instance, they’re a rich source of many vitamins and minerals including vitamin C, vitamin A, manganese, folate, copper, and magnesium. However, they’re also low in calories and high in fiber to keep you fuller for longer. As a result, they can help improve digestion, reduce blood sugar levels, improve heart health, and more!

Ingredients You’ll Need

You’re not going to believe how few ingredients you need for this recipe! 

  • Zucchini – We use whole zucchini to create zoodles ourselves. However, you can also find them already sliced in the frozen or refrigerated section of most grocery stores! Pasta Sauce – We opt for a pre-made marinara sauce, but feel free to use a homemade version or whatever you like best. 
  • Ground Beef – This bulks up the dish, making it extra filling. Due to the low carb content, we usually use a slightly higher fat beef, but whatever you have on hand works. You could also swap it out with ground turkey, chicken, or even sausage if you prefer. 
  • Extra Virgin Olive Oil – This adds heart-healthy fats and tons of flavor! 
  • Herbs and Spices – To add more flavor to the pre-made sauce and take this recipe from good to great we include a handful of herbs and spices including minced garlic, Italian parsley, fresh basil, rosemary, thyme, Herbs de Provence, and crushed red pepper.

How to Make Baked Spaghetti with Zoodles

Traditionally, baked spaghetti is made with pasta noodles that have to be boiled. However, for this version, instead of boiling spaghetti, we start by spiralizing zoodles. Then, we toss it all together for a low carb baked spaghetti recipe! Here’s what to do: 

How to Make Zoodles

As mentioned, you can absolutely buy pre-made zoodles to save some time. However, making them yourself is more budget-friendly and honestly a lot of fun! We both use a Paderno World Cuisine Spiralizer and think it’s a great tool to have in your kitchen. However, a julienne peeler works just as well. You’ll just end up with strips instead of spirals. 

Whichever tool you choose, you’ll want to chop both ends off your zucchini. Then, twist or slice your veggies, creating long spirals or thin strips that resemble pasta. 

Putting It All Together 

Once your zucchini has been transformed into noodles, this recipe comes together in minutes! 

  1. Preheat your oven to 400° Fahrenheit
  2. Brown your meat in a skillet, adding your favorite seasonings as it cooks. 
  3. Add the ingredients to a baking dish, stirring to combine. 
  4. Bake, and garnish with fresh Parmesan and basil. 
  5. Serve warm, and enjoy! 

Do I Need to Cover My Spaghetti Bake While Cooking? 

No, covering the pan with foil can lock in steam causing the zoodles to overcook and become mushy. It also prevents the cheese from becoming slightly crispy on top (which is our favorite part!). 

Make-Ahead Options

One of our favorite ways to save time is to prepare everything for this baked spaghetti ahead of time. Then, store it baked or unbaked and covered in the fridge for up to 2 days or in an airtight container in the freezer for up to 2 months. It makes for a super quick meal on those nights when you need to get dinner on the table fast! 

Serving Suggestions

Because it’s made with vegetables, this recipe makes for a complete meal that’s super light yet filling all on its own. However, it can also be paired with quick side dishes and desserts such as:

  1. Hi! I am a pescatarian, as is my family. Could I sub the meat for shrimp or salmon? What adjustments would you make? Cook fish raw or cooked when baking with zoodles?

  2. 5 stars
    Loved this! Quick, easy! I just used my homemade Italian seasoning blend for a shortcut, and substitute a ground turkey for the beef. Delicious!
