Pro Tips

• For easier eating, you can peel the shrimp before baking, leaving the tails on for a classic look. However, cooking with the shells on imparts a deeper, more robust flavor into the sauce.
• Rinse kelp noodles thoroughly under cold water to remove their natural briney scent. For a softer, more pasta-like texture, soak them in warm water with a splash of lemon juice for 10-15 minutes before using.
• Add a pinch of red pepper flakes to the butter sauce for a touch of heat, or a splash of dry white wine (like Pinot Grigio) for a more complex, traditional scampi flavor.
• Don’t let any of that garlic butter sauce go to waste! Serve with keto-friendly garlic bread or a side of steamed asparagus for dipping.

FAQ

Q: What are kelp noodles and what do they taste like
A: Kelp noodles are a low-carb, gluten-free pasta alternative made from seaweed. They have a neutral taste and a crisp texture. Rinsing them thoroughly, as the recipe suggests, removes any briney scent and allows them to perfectly absorb the rich garlic butter sauce.

Q: Can I use a different low-carb noodle instead of kelp noodles
A: Yes, if you don’t have kelp noodles, you can easily substitute them with other keto-friendly options like zucchini noodles (zoodles), spaghetti squash, or even serve the scampi over a bed of cauliflower rice.

Q: Should I cook the shrimp with the shells on or off
A: For the best flavor, we recommend cooking the shrimp with the shells on. The shells impart a deeper, more robust seafood flavor into the garlic butter sauce. For easier eating, you can peel them before baking, leaving just the tails on for a classic look.

Q: How can I add more flavor to this keto scampi
A: To enhance the flavor, you can add a pinch of red pepper flakes to the butter sauce for a bit of heat. For a more traditional scampi taste, add a splash of dry white wine, such as Pinot Grigio, to the sauce before pouring it over the shrimp.
