Step 1: Prepare the Rice Noodles ; Cook rice noodles according to package instructions until al dente. Drain and rinse under cold water to prevent sticking. Set aside.
Step 2: Sauté Aromatics : In a large pot, heat vegetable oil over medium heat. Add chopped onions, minced garlic, and grated ginger. Sauté until fragrant and translucent, about 3–4 minutes.
Step 3: Add Curry Paste and Spices : Stir in red curry paste, chopped lemongrass, turmeric powder, and paprika. Cook for 2 minutes, stirring constantly to release the aromas.
Step 4: Cook the Pork : Add the thinly sliced pork to the pot and cook until slightly browned on all sides, about 3–4 minutes.
Step 5: Add Liquids and Seasoning : Pour in the chicken or pork broth and coconut milk. Stir in fish sauce, soy sauce, and sugar. Bring the soup to a gentle simmer and cook for 10–12 minutes until the pork is tender.
Step 6: Add Vegetables : Add baby spinach or bok choy to the soup during the last 2–3 minutes of cooking. Stir gently to wilt the greens.
Step 7: Assemble the Bowls : Divide cooked rice noodles into serving bowls. Ladle the pork curry soup over the noodles. Top with bean sprouts, sliced green onions, chopped cilantro, red chili, and a wedge of lime.
