Prepare your ingredients. If using frozen shrimp, thaw them in the refrigerator overnight or in cold water for about 20 minutes. Peel and devein if necessary.
Heat olive oil in a large pot over medium heat. Add onion and bell pepper, sauté for 3-4 minutes until translucent.
Add minced garlic, stirring for about 30 seconds until aromatic.
Pour in vegetable broth and bring to a gentle simmer, scraping the bottom of the pot.
Add sweet corn to the pot, stirring well to combine.
Season with salt, black pepper, cayenne pepper, and thyme to taste. Simmer for about 10 minutes.
Add coconut milk, stirring to mix well, and heat through for another 5 minutes.
Add shrimp and cook for an additional 3-4 minutes until shrimp are pink and opaque.
Adjust seasonings as needed. For a thinner bisque, add more vegetable broth.
Remove from heat and let cool slightly. Optionally, use an immersion blender for a smoother texture.
Serve hot, garnished with parsley. Enjoy with crusty bread or over rice.
Notes
This bisque can be made ahead of time and tastes even better the next day. Store leftovers in an airtight container for up to three days.
