Keto Zucchini Noodle Meatballs - A Light, Comforting Low-Carb Favorite
Ingredients
Method
- Prep the zucchini noodles. Spiralize the zucchinis and spread the noodles on a clean towel. Lightly salt and let them sit for 10 minutes to draw out moisture.Pat dry to prevent sogginess later.
- Mix the meatballs. In a bowl, combine ground meat, Parmesan, almond flour, egg, garlic, parsley, Italian seasoning, onion powder, salt, and pepper. Mix gently with your hands until just combined. Don’t overmix, or the meatballs will be dense.
- Shape and rest. Roll into 1.5-inch meatballs. Place on a plate and let them rest 5–10 minutes.This helps them hold together when cooking.
- Cook the meatballs. Choose your method: Pan-sear: Heat olive oil in a large skillet over medium-high. Brown meatballs on all sides, 6–8 minutes. Lower heat to medium, cover, and cook until done, about 5 more minutes.
- Bake: Preheat to 400°F (200°C).Place meatballs on a parchment-lined sheet and bake 15–18 minutes, or until cooked through.
- Warm the sauce. In a saucepan, heat olive oil over medium. Add garlic and red pepper flakes; cook 30 seconds until fragrant. Stir in marinara, season with salt and pepper, and simmer 5–8 minutes.If you baked the meatballs, slide them into the sauce to coat.
- Sauté the zucchini noodles. In a large skillet, heat olive oil or butter over medium. Add zoodles and cook 1–2 minutes, tossing gently until just tender. Season with a pinch of salt. Do not overcook—they soften quickly.
- Plate and finish. Divide zucchini noodles into bowls, top with meatballs and sauce, and finish with fresh basil, extra Parmesan, and a touch of lemon zest if you like.

Keeping It Fresh
Store meatballs and sauce together in an airtight container for up to 4 days.
Keep the zucchini noodles separate, uncooked if possible. They release water over time, so pat them dry again before reheating.
For reheating, warm the meatballs and sauce gently on the stovetop. Toss fresh or briefly sautéed zoodles in just before serving. Freezing tip: Freeze the cooked meatballs and sauce (not the zoodles) for up to 3 months.
Thaw overnight and reheat on low heat.
Health Benefits
- Low in carbs, high in satisfaction: Zucchini keeps carbs low while giving you the pasta vibe.
- Protein-rich: The meatballs offer steady energy and support muscle repair.
- Healthy fats: Olive oil and cheese provide fats that help you feel full and support keto goals.
- Micronutrient boost: Zucchini adds vitamin C, potassium, and fiber for digestion and hydration.
- Fewer additives: Using sugar-free marinara helps you avoid hidden sugars and keep your macros clean.
What Not to Do
- Don’t skip salting and drying the zoodles. Excess moisture creates a watery bowl and bland flavor.
- Don’t overmix the meatball mixture. Overworking the meat makes tough, rubbery meatballs.
- Don’t overcook the zoodles. Two minutes is plenty. Any more and they turn mushy.
- Don’t forget to check the marinara label. Many store-bought sauces hide sugar. Choose one with simple ingredients and no added sugar.
- Don’t crowd the pan. If pan-searing, cook meatballs in batches for a good crust.
Alternatives
- Protein swaps: Use ground turkey, chicken, or a 50/50 mix of beef and Italian sausage.Adjust seasonings to taste.
- Binder options: If you don’t have almond flour, use crushed pork rinds or coconut flour (start with 1–2 tbsp; it absorbs more moisture).
- Dairy-free: Skip Parmesan and add 1 extra tablespoon of almond flour plus 1 teaspoon nutritional yeast for a savory note.
- Extra veggies: Add finely chopped spinach or grated zucchini (squeeze out moisture) into the meatball mix.
- Sauce twist: Try a creamy garlic Alfredo made with heavy cream, Parmesan, and butter for an ultra-rich version.
- Spice level: Add smoked paprika, chili flakes, or a splash of hot sauce to the meatballs for heat.
FAQ
Can I make the meatballs ahead of time?
Yes. Shape them and refrigerate up to 24 hours before cooking, or freeze raw meatballs on a sheet tray, then transfer to a bag. Cook from frozen by adding a few extra minutes.
How do I prevent watery zucchini noodles?
Salt, rest, and pat dry before cooking.
Use medium heat and cook briefly. If your sauce is thin, simmer it a few extra minutes to thicken before adding meatballs.
Is this recipe gluten-free?
Yes, as written it’s gluten-free. Just confirm your marinara and seasonings are certified gluten-free if needed.
What’s the best marinara for keto?
Look for a brand with no added sugar and simple ingredients like tomatoes, olive oil, garlic, onions, and herbs.
Aim for around 4–6 grams net carbs per half cup.
Can I air-fry the meatballs?
Absolutely. Air-fry at 390°F (200°C) for 10–12 minutes, shaking once, until browned and cooked through. Toss in warm sauce to finish.
How do I know when meatballs are done?
They should be browned on the outside and reach an internal temperature of 160°F (71°C) for beef/pork.
If you don’t have a thermometer, cut one open to ensure it’s no longer pink inside.
Can I use pre-spiralized zucchini?
Yes, but check freshness. Pre-spiralized zoodles can be wetter, so pat them dry well and cook quickly.
What if I don’t eat dairy?
Skip the Parmesan and use extra almond flour or nutritional yeast for flavor. Adjust salt to taste since Parmesan adds saltiness.
How can I add more flavor without more carbs?
Use fresh herbs, lemon zest, extra garlic, a drizzle of good olive oil, or a pinch of red pepper flakes.
These add punch without affecting carbs much.
Can I serve this to kids?
Definitely. Keep the spice mild, and you can cut the zoodles shorter for easier eating. Many kids enjoy the fun noodle shape and tender meatballs.
