Instructions
- Step 1: Preheat oven to 400°F (200°C). Place spaghetti squash halves, cut-side up, on a baking sheet. Drizzle with 1 tbsp olive oil and season with salt and pepper. Roast 30 minutes until tender and golden. Scrape flesh with a fork to create 'noodles'.
- Step 2: In a large skillet, heat 1 tbsp olive oil over medium heat. Add shrimp and 1 tsp garlic. Cook 3-4 minutes until pink and opaque. Remove shrimp and set aside.
- Step 3: In the same skillet, add pesto, remaining 1 tsp garlic, lemon zest, and 1 tbsp lemon juice. Stir to combine. Add spaghetti squash noodles and toss to coat. Return shrimp to the skillet. Sprinkle with basil and parmesan. Toss gently and serve.
