Ingredients You'll Need

Great soup starts with great components, but that doesn’t mean you need to break the bank or hunt down exotic items. Below is the curated lineup that makes this keto chicken zoodle soup sing, plus my tried-and-true buying tips so you can shop like a pro.

Avocado oil (2 Tbsp): I prefer avocado for its high smoke point and neutral flavor, but organic cold-pressed is worth the splurge—no weird aftertaste to muddy your broth. If you’re in a pinch, refined coconut oil or ghee works, though ghee will add a buttery note.

Yellow onion (1 medium, diced): Look for firm bulbs with tight, papery skins. Avoid any green sprouts; they signal age and bitterness. Dice small so they melt into the background within minutes.

Celery (2 stalks, sliced): Choose the pale, inner hearts—they’re more tender and subtly sweet. Save the leafy tops for garnish; they pack a concentrated celery punch.

Carrot (1 medium, julienned): Yes, carrots on keto—in moderation. One carrot across four servings adds color and 1.6 g net carbs per bowl. Opt for slender organic carrots; they’re naturally sweeter and don’t need peeling.

Garlic (3 cloves, minced): Fresh only, please. Jarred garlic sits in citric acid that can dull flavor. Smash, salt, and mince to a paste so it disperses evenly.

Fresh thyme (2 tsp leaves): Thyme and chicken are soulmates. Strip leaves by running pinched fingers down the stem. Dried thyme is fine in a pinch—use ¾ tsp.

Turmeric (½ tsp ground): Adds anti-inflammatory curcumin and a golden glow. Pair with black pepper to boost absorption.

Chicken bone broth (6 cups): Homemade is liquid gold, but Kettle & Fire or Bonafide Provisions are my go-to boxed brands. Check labels—some “bone broths” are just stock with marketing lipstick.

Cooked chicken (3 cups shredded): Rotisserie is convenient, but I roast skin-on, bone-in breasts on Sunday, drizzle with olive oil, sprinkle sea salt, and bake at 425 °F for 22 minutes. Cool, shred, and you’re set for the week.

Zucchini (4 medium, spiralized): Pick small, firm zucchini—oversized ones hide watery cores that deflate into mush. If you don’t own a spiralizer, many grocers sell fresh zoodles in the produce section. Pro tip: pat them dry with a lint-free towel before using.

Lemon (1, zested & juiced): Brightness is everything. Zest first, then juice; the oils in the zest amplify aroma. Meyer lemons lend a sweeter perfume if you can find them.

Fresh parsley (¼ cup, chopped): Flat-leaf (Italian) holds up better in heat than curly. Chop just before serving to keep that verdant pop.

Sea salt & black pepper: I use coarse Celtic sea salt for its mineral complexity and crack peppercorns in a mortar for fresher bite.

How to Make Keto Chicken Zoodle Soup for Low Carb Lunch

Warm the pot

Place a heavy-bottomed 4-quart soup pot over medium heat for 60 seconds. This brief pre-heat prevents the aromatics from sticking and encourages even sautéing.

Sauté the trinity

Add avocado oil, swirl to coat, then scatter in diced onion and celery plus a pinch of salt. Sweat for 4 minutes until edges turn translucent. Stir occasionally; you want soft, not brown. Add julienned carrot and cook 2 minutes more.

Bloom the aromatics

Clear a small circle in the center of the pot, reduce heat to medium-low, and add minced garlic, thyme, turmeric, and ¼ tsp pepper. Stir constantly for 45 seconds until fragrant; this wakes up the spices without burning.

Deglaze & simmer

Pour in bone broth, raise heat to high, and bring to a rolling boil. Use a wooden spoon to scrape the tasty browned bits (fond) off the bottom—free flavor! Once boiling, reduce to a gentle simmer, cover partially, and cook 8 minutes to marry flavors.

Add chicken

Stir in shredded chicken and simmer 3 minutes to heat through. Taste broth; add salt gradually—bone broths vary widely in sodium.

Zoodle time

Turn heat to low. Add zucchini noodles and immediately remove pot from burner. Let stand 2 minutes; residual heat softens zoodles to al dente perfection without waterlogging.

Finish fresh

Stir in lemon zest, juice, and parsley. Ladle into shallow bowls (deep bowls trap steam and continue cooking zoodles). Serve piping hot with an extra crack of black pepper.

Expert Tips

Salt in stages

Season lightly at each layer—onions, broth, finish—so flavors build rather than correct at the end.

Zoodle sizing

Use the medium noodle blade (⅛-inch) on your spiralizer; anything thinner collapses, anything thicker feels like veggie pasta.

Double-stock hack

For deeper body, whisk 1 tsp gelatin into store-bought broth while it heats; it mimics the silkiness of long-simmered stock.

Keep them green

A quick ice-water rinse after spiralizing halts browning enzymes and keeps zoodles vibrant through Friday.

Thermos trick

Pack soup in a pre-heated thermos but store zoodles separately; combine just before eating for lunch-room al dente.

Carrot math

If you’re ultra-strict keto, swap carrot for ½ cup diced red bell pepper; drops net carbs to 4 g per serving.

Variations to Try

Creamy Tuscan: Stir in ½ cup heavy cream and ¼ cup sun-dried tomatoes with the chicken for a richer, restaurant-style twist.
Thai Coconut: Swap bone broth for 4 cups chicken stock + 2 cups coconut milk, add 1 Tbsp red curry paste, and finish with cilantro and lime.
Green Veg Boost: Fold in 2 cups baby spinach at the same time as zoodles; it wilts instantly and ups the micronutrients.
Spicy Chipotle: Add ½ minced chipotle in adobo with the garlic and finish with a diced avocado on top.
Turkey & Kale: Sub shredded turkey and ribbon-cut lacinato kale; simmer 1 minute longer to soften kale edges.
Seafood Remix: Replace chicken with peeled shrimp; add during final 2 minutes of simmer until just pink.

Storage Tips

Refrigerator: Cool soup completely, transfer to glass jars, and refrigerate up to 5 days. Keep zoodles in a separate zip-top bag lined with paper towel to prevent moisture creep. Combine when reheating.

Freezer: Freeze broth and chicken (without zoodles) in silicone Souper-Cubes or pint jars, leaving 1-inch headspace, for up to 3 months. Thaw overnight in fridge, bring to a simmer, and add fresh zoodles.

Reheat: Warm gently over medium-low, stirring often. Boiling turns zoodles to mush. If using microwave, heat soup first, then stir in zoodles and let stand 1 minute.

Make-ahead zoodles: Spiralize up to 4 days ahead, toss with ½ tsp salt, let drain in a colander 15 minutes, rinse, pat dry, and store in paper-towel lined container. They stay crisp and don’t weep into your lunchbox.
