There is nothing more comforting on a cold winter day than a warm bowl of chicken “noodle” soup — especially when it nourishes your body instead of spiking your blood sugar. This Low Carb Gluten Free Keto Chicken Zoodle Soup is the ultimate guilt-free comfort food: cozy, flavorful, full of fresh ingredients, and ready in under 30 minutes.

Keto Chicken Zoodle Soup (Low Carb & Gluten Free)

Instead of traditional noodles, this recipe uses spiralized zucchini “zoodles,” making it a delicious keto chicken soup that fits perfectly into a ketogenic lifestyle or low-carb way of eating.

Now that my kids are older, I don’t have to sneak vegetables into every meal anymore — but I still love serving dishes that make all of us feel warm, nourished, and cared for. 

When the temperatures drop, when someone in the house needs a little extra comfort, or when I just want an easy weeknight dinner with zero fuss and zero gluten, this soup is one of my favorite ways to gather everyone around the table.

It tastes like home, freezes beautifully, makes incredible leftovers, and keeps me on track with my goals — especially during the fall and winter months.

Zoodle Soup Recipe

If you’ve never tried zoodle soup before, get excited — it’s shockingly satisfying and perfect for keto recipes. Zoodles give you the nostalgic feel of chicken “noodle” soup without the carbs, wheat, or heaviness of traditional pasta. 

This recipe is naturally:

✔ Low Carb

✔ Keto Friendly

✔ Gluten Free

✔ Grain Free

✔ High in Protein

✔ Dairy Free (optional)

With just a handful of simple, fresh ingredients like chicken, broth, carrots, onion, garlic, fresh herbs, and zucchini, you’ll have a big bowl of soup of wholesome goodness that soothes both body and soul.

This soup is also fantastic for meal prep, easy to freeze in airtight containers or freezer bags, and makes a perfect freezer meal for future sick days or busy nights.

When I made my lemon poached chicken and broth I knew I wanted to make a chicken soup for the blog, but I don’t eat pasta so I thought the zucchini noodles would be tasty and I was right. They hold their texture and for me it’s just as good as pasta only better knowing it’s low carb!

What Are Zoodles? (Zucchini Noodles 101)

Zoodles are simply spiralized zucchini, sliced into long, pasta-like strands. They’re:

Mild in flavor, making them an ideal noodle replacement

Naturally low in carbs

Gluten- and grain-free

Lower in calories than pasta

Fast-cooking

To make zoodles, you can use:

• A spiralizer (best texture)
• A julienne peeler
• A mandoline
• Pre-spiralized zoodles from the store (a great shortcut)

They hold up beautifully in soup when added at the very end — giving that classic “noodle” texture in just minutes.

Why Choose Zoodles Over a Traditional Noodle?

Traditional chicken noodle soup is made with wheat noodles which are high in carbs, gluten and can spike blood sugar quickly. 

Zoodles, on the other hand, let you enjoy all the cozy nostalgia of chicken noodle soup while keeping net carbs low.

This keto chicken noodle recipe has only about 4 g net carbs per serving, making it a perfect option for anyone following a keto diet, low carb lifestyle, or gluten free comfort-food approach.

Will zucchini noodles get soggy?

Not if you add them at the end and simmer just 3–5 minutes.

Can I freeze this keto chicken noodle soup with zoodles?

It’s best to freeze without the zucchini noodles and add them fresh when reheating.

Can I use leftover chicken or rotisserie chicken?

Yes — it’s one of the best shortcuts!

Can I make this dairy free?

Absolutely. Just skip the Parmesan garnish.

Keto Noodle Alternatives (If You Don’t Love Zucchini)

Not a zucchini fan, or want to switch it up? Try any of these low carb noodle options:

• Palmini noodles (hearts of palm)
• Cabbage “noodles” (thin-shredded — shockingly good!)

Instant Pot Variation

Slow Cooker Variation

2. Cook on Low 5–6 hours or High 2–3 hours.
3. Add zoodles during the last 10–15 minutes of cook time.

Substitutions

Parmesan cheese for a cozy, salty finish (optional)

Spinach instead of kale

Chicken thighs or rotisserie chicken instead of chicken breast

Bone broth instead of broth for added nutrients

Bay leaf, thyme, or parsley for more classic flavor

Meal Prep, Leftovers & Freezer Tips

Freezer bags work great for stacking flat in small freezer spaces.

Refrigerate: Store in airtight containers up to 4 days.

Freeze: Freeze broth + chicken + veggies without zoodles for best texture (up to 3 months).

Reheat: Add fresh zoodles after reheating so they don’t get soggy.

Optional Lemon Twist

If you love a bright, fresh pop of flavor, add 2 tablespoons fresh lemon juice at the end. My husband prefers less lemon, so I include it as an optional variation — but it does add a lovely, refreshing note to the broth.
