Ingredients
- Servings: 4
- Preparation time: 10 minutes
- Cooking time: 10 minutes
- Total time: 20 minutes
- 400g (approx. 14oz) fresh or frozen peeled shrimp, thawed if frozen and patted completely dry
- 3 large courgettes (zucchini), spiralized into noodles
- 60ml (approx. 2 tbsp) unsalted butter, divided
- 4 cloves garlic, minced finely
- 150ml (approx. 1/3 cup) dry white wine or chicken broth
- 1 tsp lemon juice
- 1 tsp fresh thyme leaves, chopped
- Salt and freshly ground black pepper to taste
- Parmesan cheese for serving (optional)
Method
Preparation: Rinse the spiralized courgette noodles under cold water to remove excess starch. Drain thoroughly in a clean kitchen towel or paper towels; this prevents the noodles from becoming slimy.
Cooking the Shrimp: Heat 20g of the butter in a large skillet over medium-high heat. Add the shrimp in a single layer. Cook for 1–2 minutes per side until pink and opaque. Remove shrimp from the pan and set aside on a plate.
Sautéing the Noodles: In the same pan, add another 20g of butter. Toss in the courgette noodles and cook for 3–4 minutes, stirring frequently. They should be tender-crisp but still have a slight bite; overcooking releases too much water.
Making the Sauce: Add the minced garlic to the pan with the noodles and cook for 30 seconds until fragrant. Pour in the white wine or broth, scraping up any browned bits from the bottom of the pan. Let it simmer for 2 minutes to reduce slightly.
Finishing: Stir in the lemon juice and thyme. Return the shrimp to the pan with the sauce. Toss gently to coat everything evenly. Season with salt and pepper. Serve immediately, topped with parmesan if desired.
Troubleshooting Common Issues
Problem: Courgette noodles are too watery or mushy.
Cause: Too much starch from unwashed or un-drained zucchini, or cooking time exceeding tenderness.
Fix: Always rinse and drain the noodles thoroughly before cooking. If they seem wet, remove them from heat briefly to evaporate moisture before adding garlic.
Problem: Shrimp turns rubbery or gray.
Cause: Overcooking due to high heat or overcrowding the pan.
Fix: Cook shrimp over medium-high heat, not searing hot. Do not crowd the pan; cook in batches if necessary. Shrimp is done when it turns pink and curls into a ‘C’ shape.
Problem: Sauce separates or becomes oily.
Cause: Adding butter too late or insufficient liquid reduction.
Fix: Ensure the garlic has cooked down before adding liquid. Allow the wine or broth to reduce by half before reintroducing the shrimp and final butter additions.
Suitable Substitutions
- Courgette noodles: If spiralizers are unavailable, thin slices of courgette can be sautéed until tender instead. Cauliflower rice is another low-carb alternative, though it offers a different texture.
- Shrimp: Cooked chicken breast or calamari work well in this sauce. Adjust cooking time based on the protein’s thickness.
- Butter: Ghee or olive oil can be used, though butter provides a richer mouthfeel for this specific flavor profile.
Storage and Reheating
This dish is best enjoyed fresh due to the texture of the shrimp and noodles. If stored, keep in an airtight container in the refrigerator for up to 3 days. Reheat gently in a microwave or warm through in a skillet with a splash of cream or broth to restore moisture.
Frequently Asked Questions
Can I make this meal ahead?
While you can assemble the ingredients, the shrimp and sauce are best made fresh. Reheating cooked shrimp often alters their texture, making them less tender.
Is this dish suitable for a ketogenic diet?
Yes, courgette and shrimp are naturally low in carbohydrates. This meal typically contains fewer than 5g of net carbs per serving, fitting most standard keto guidelines.
