Cook shrimp: Add 1 tablespoon oil to a large pot. Sauté shrimp over medium high heat until they are fully cooked (should take about 4-5 minutes). Remove shrimp from the pot and set aside.
Cook vegetables: Add 1 tbsp oil to the same pot. Add in carrots and onions and cook for 4-5 minutes or until the vegetables start to get tender. Add in garlic and ginger and cook for an additional minute.
Simmer broth: Stir in curry paste, broth and fish sauce. Bring to a boil then reduce to a simmer and cook for 10 minutes.
Stir in coconut milk and mushrooms. Cook for 3-4 minutes or until mushrooms are tender. Add the cooked shrimp back to the pot along with the lime juice and cilantro. Stir to combine and serve immediately.
