Instructions

Save

1. Prep the zoodles: Spiralize the zucchini and set aside on a towel to absorb moisture. Pat dry gently to prevent a watery soup.
2. Season the shrimp: Pat the shrimp dry and season with a pinch of salt, pepper, and a small pinch of red pepper flakes.
3. Sauté aromatics: In a large pot, heat the oil over medium heat.

   Add the white parts of the green onions, garlic, and ginger. Cook 1–2 minutes until fragrant, stirring often.

4. Build the broth: Pour in the broth. Add lemon zest and the optional fish sauce or coconut aminos.

   Bring to a gentle simmer.

5. Cook the shrimp: Add shrimp and cook 2–4 minutes, just until pink and opaque. Do not overcook. Use a slotted spoon to transfer the shrimp to a bowl to prevent overcooking while you finish the soup.
6. Add greens and zoodles: Stir in spinach and the zucchini noodles.

   Simmer lightly for 1–2 minutes until the spinach wilts and the zoodles are just tender (still slightly crisp).

7. Finish and season: Return the shrimp to the pot. Stir in lemon juice, butter or ghee (if using), and most of the chopped herbs. Taste and adjust salt, pepper, and heat with more red pepper flakes if needed.
8. Serve: Ladle into bowls and top with the remaining green onion tops and herbs.

   Serve right away while the zoodles are perfectly tender.

Storage Instructions

• Short-term: Store leftovers in an airtight container in the fridge for up to 2 days.
• Reheating: Warm gently on the stove over low heat until hot. Avoid boiling so the shrimp doesn’t get rubbery and the zoodles don’t go mushy.
• Make-ahead tip: Keep the cooked shrimp and broth in one container and the zoodles separately. Combine and heat just before serving for the best texture.
• Freezing: Not ideal with zoodles.

  If you want to freeze, freeze the broth and shrimp without the zucchini, then add fresh zoodles when reheating.

Why This is Good for You

• Keto-friendly: Zucchini keeps net carbs low while still giving you that noodle experience.
• High-quality protein: Shrimp provides lean protein plus iodine, selenium, and B vitamins.
• Anti-inflammatory ingredients: Garlic, ginger, lemon, and leafy greens bring antioxidants and micronutrients.
• Light on the gut: A clean broth base is soothing and easy to digest, especially after a heavy day of eating.

Common Mistakes to Avoid

• Overcooking the shrimp: Shrimp cook fast. Pull them out as soon as they turn pink and firm, then add back at the end.
• Watery soup from wet zoodles: Pat the zoodles dry and add them near the end to avoid excess water and mushy texture.
• Boiling too hard: A rolling boil toughens shrimp and breaks down zucchini. Keep it at a gentle simmer.
• Skipping the acid: Lemon juice brightens the broth and balances richness.

  Don’t skip it.

• Under-seasoning: Taste at the end and adjust salt and pepper. Broths vary in saltiness.

Variations You Can Try

• Creamy version: Stir in 1/3 cup heavy cream or coconut milk at the end for a richer soup. Add a squeeze of lemon to keep it bright.
• Thai-inspired: Use coconut milk, a spoon of red or green curry paste, and finish with lime, cilantro, and a dash of fish sauce.
• Garlic-parmesan: Add extra garlic and finish with grated Parmesan (if you include dairy in your keto plan).
• Extra veggies: Toss in thin-sliced mushrooms, bok choy, or bell peppers.

  Sauté these with the aromatics before adding broth.

• Protein swap: Use chicken breast, scallops, or firm white fish. Adjust cooking times so proteins stay tender.
• Spice it up: Add a sliced fresh chili or a bit of chili oil for heat lovers.

FAQ

Can I use frozen shrimp?

Yes. Thaw them in the fridge overnight or under cold running water, then pat dry well before cooking.

Excess moisture can dilute the broth and make it harder to sear flavor into the soup.

How do I make zoodles if I don’t have a spiralizer?

Use a julienne peeler or a standard vegetable peeler to make thin ribbons. You can also buy pre-spiralized zucchini in many grocery stores—just pat them dry before adding.

Will this soup fit into strict keto macros?

It’s very low in net carbs and high in protein, especially if you use a low-carb broth. For stricter macros, skip the onion whites or reduce green onions and keep an eye on portion sizes.

What can I use instead of zucchini?

Try spiralized yellow squash, shirataki noodles, or cabbage ribbons.

All keep carbs low while giving you that noodle-like bite.

How can I make the broth more flavorful?

Toast the garlic and ginger lightly, add lemon zest, and use fish sauce or coconut aminos for depth. Simmer the aromatics for a few extra minutes before adding the shrimp to build more flavor.

Is this recipe dairy-free?

Yes, as written it’s dairy-free unless you add butter or Parmesan. Use olive oil and skip the butter to keep it dairy-free.

Can I meal prep this?

Absolutely.

Prep the broth and shrimp ahead, store zoodles separately, and combine when reheating. This keeps the zucchini from getting soggy.

In Conclusion

Keto Shrimp and Zoodle Soup is a fast, flavorful bowl that checks all the boxes: light, comforting, and easy to make. With fresh aromatics, bright lemon, and tender shrimp, it tastes clean and satisfying without the carbs.

Keep it simple for weeknights or dress it up with one of the variations. Either way, you’ll get a warm, nourishing soup that feels good any day of the week.
