Heat coconut oil in a large pot over medium/high heat. When the oil is melted and hot, add the sweet potatoes, carrots, and ¼ teaspoon of salt to the oil and toss. Let the vegetables cook for 7-10 minutes, stirring occasionally.
Next, add garlic, onion, and red pepper to the pot, toss, and cook for another 2-3 minutes.
Add the coconut milk and curry paste to the pot and whisk the ingredients together until the curry paste is combined with the coconut milk. Then, add the broth, sriracha, green onion, cilantro, and lime juice to the pot and stir to combine. Bring the ingredients to a boil.
Turn the heat to low, add the frozen peas, and let the soup simmer for 10-15 minutes.
While the soup is simmering, prepare the rice noodles separately. Bring a large pot of salted water to a boil and then remove the pot from the heat. Add the rice noodles to the hot water and stir. Let the noodles sit in the hot water for 3-4 minutes. Make sure the noodles have a bite and are a bit undercooked as they will continue to cook in the soup. Strain the noodles and rinse with cold water. Set aside.
When the soup is hot and the peas are cooked, remove from heat and serve with rice noodles, cilantro, green onion, and jalapeño.
