Keto Garlic Shrimp Zucchini Noodles Recipe: A 15-Minute Low-Carb Pasta Alternative

What are zucchini noodles? Zucchini spiralised or peeled into long, pasta-like strands — often called zoodles — that carry sauce, absorb flavour, and deliver the visual and textural satisfaction of a pasta bowl at approximately 4g net carbs per generous portion. This garlic shrimp version combines golden-seared prawns with a butter-garlic sauce and fresh zoodles for a restaurant-quality plate that takes 15 minutes from start to table.

Zucchini noodles are one of the keto kitchen’s most reliable pasta replacements — not because they taste like pasta (they don’t), but because they carry sauce beautifully, provide real textural substance, and look the part on a plate. The garlic butter sauce and fresh prawns do the heavy lifting on flavour. The zoodles simply deliver it to the fork.

Why Zucchini Noodles Are the Best Keto Pasta Swap

Traditional pasta contains 35–40g net carbs per 100g dry weight. Zucchini noodles contain approximately 2.5g net carbs per 100g. For a keto eater who misses pasta, that gap — 35g versus 2.5g — is the difference between a diet compromise and a genuine meal. They’re also lighter than pasta, which means the sauce (and in this case, the prawns) become the star rather than being overwhelmed by heavy carbohydrate bulk.

Ingredients You Will Need

• 450g (1 lb) large raw prawns (shrimp), peeled and deveined
• 3–4 medium zucchini, spiralised or peeled into noodles
• 3–4 cloves garlic, minced
• 2 tablespoons butter
• 1 tablespoon olive oil
• ¼ teaspoon red pepper flakes
• 1 teaspoon Italian seasoning or dried oregano
• Salt and black pepper
• Fresh parsley and grated parmesan, to serve
• Lemon wedges, to serve

How to Make Keto Garlic Shrimp Zucchini Noodles: Step-by-Step

1. Prepare the zoodles: Spiralise or peel zucchini into noodles. Lay on paper towels, salt lightly, and leave 10 minutes to draw out excess moisture. Pat dry. This prevents the zoodles from releasing water into the sauce during cooking.
2. Sear the prawns: Heat olive oil in a wide pan over high heat. Season prawns with salt and pepper. Add to hot pan in a single layer — don’t crowd. Cook 1 minute per side until pink and slightly golden at the edges. Remove immediately to a bowl — overcooked prawns turn rubbery in seconds.
3. Build the garlic sauce: Reduce heat to medium. In the same pan, add butter. When melted, add garlic, Italian seasoning, and red pepper flakes. Stir for 60 seconds until garlic is fragrant and lightly golden.
4. Add zoodles: Add the dried zucchini noodles to the pan. Toss with the garlic butter for 2 minutes — just until slightly tender. You want them yielding, not soft and mushy.
5. Combine and serve: Return the prawns to the pan and toss everything together for 30 seconds. Season to taste. Plate immediately and top with parmesan, parsley, and a squeeze of lemon.

Tips for Perfect Garlic Shrimp Zoodles

• Salt and dry the zoodles before cooking. Zucchini is 95% water — if that water enters the pan during cooking, the garlic butter sauce becomes watery and flavourless. Salt, wait 10 minutes, and pat completely dry.
• Cook zoodles for 2 minutes maximum. They continue cooking from residual heat after leaving the pan. Pull them at slightly under-done — they’ll be perfect by the time they hit the plate.
• Sear the prawns hot and fast. Prawns take 60–90 seconds per side over high heat. They go from perfect to overcooked very quickly — watch them closely and remove the moment they curl into a C shape.
• Serve immediately. Zoodles continue releasing moisture as they sit. This is not a dish to let rest — eat it straight from the pan.

Frequently Asked Questions

Are zucchini noodles keto-friendly? Yes — approximately 2.5g net carbs per 100g, making them one of the lowest-carb pasta alternatives available. A full portion of zoodles from 2–3 medium zucchini delivers under 8g net carbs total.

How do I make zucchini noodles without a spiraliser? Use a vegetable peeler to create wide, flat noodles (similar to pappardelle), or a julienne peeler for thinner strips. A sharp knife and steady hand can also produce decent results with practice.

Can I substitute chicken for prawns? Yes — thinly sliced chicken breast or thigh works well. Cook the chicken fully before removing from the pan (5–6 minutes), then proceed with the garlic butter sauce.

Key Takeaways

• Salt and dry zoodles before cooking — moisture is the enemy of this dish.
• Sear prawns hot and fast — 60 seconds per side maximum.
• Cook zoodles 2 minutes only — they overcook quickly.
• Serve immediately — zoodles continue softening as they sit.
• Approximately 4g net carbs per serving.

Fifteen minutes, one pan, and a plate that looks like effort — keto garlic shrimp zucchini noodles are the weeknight recipe that earns the “you actually cooked this?” response every time.
