Pat the shrimp dry with paper towels and season evenly with sea salt and black pepper.
Heat the coconut oil in a large skillet over medium-high heat until it begins to shimmer.
Add the shrimp to the skillet and sear for 1-2 minutes per side until they turn pink and opaque, then remove from the pan and set aside.
In the same skillet, add the sliced red bell pepper and sauté for 3 minutes until slightly softened.
Stir in the minced garlic, grated ginger, and red curry paste, cooking for 1 minute until the aromatics are fragrant.
Pour in the full-fat coconut milk and bring to a gentle simmer, scraping up any flavorful browned bits from the bottom of the pan.
Add the baby spinach and stir until just wilted into the sauce.
Return the cooked shrimp to the skillet, tossing to coat in the creamy sauce and heating through for 1 minute.
Squeeze fresh lime juice over the curry and garnish with chopped cilantro before serving immediately.
