Tender grilled octopus drizzled with aromatic lemongrass-calamansi butter, served with a diabetic-friendly shirataki coconut sticky rice that delivers exotic flavors without the blood sugar spike.

Description

This Grilled Octopus with Lemongrass-Calamansi Butter transforms the intimidating cephalopod into an approachable, elegant dish that's both sophisticated and blood sugar-friendly. The recipe takes inspiration from Filipino coastal cooking traditions while incorporating Southeast Asian aromatics for a fusion that feels both novel and familiar.

The octopus is first tenderized through a gentle simmer with aromatics, then charred on a hot grill to develop smoky notes and caramelized edges. This two-stage cooking process ensures the perfect texture—tender with just the right amount of chew. The real magic happens when the hot octopus is drizzled with a compound butter infused with fragrant lemongrass, bright calamansi citrus, and a hint of chili heat. As the butter melts over the warm octopus, it creates an instant sauce that's rich, aromatic, and perfectly balanced.

Instead of traditional sticky rice, this dish features an innovative shirataki rice substitute infused with coconut milk, pandan, and a touch of coconut cream. Shirataki, made from the konjac yam, provides the chewy texture of sticky rice with a fraction of the carbohydrates. The coconut milk and subtle seasonings transform this virtually carb-free ingredient into a satisfying base that mimics the indulgent mouthfeel of traditional sticky rice.

The result is a restaurant-worthy dish that feels indulgent while supporting stable blood sugar levels—proving that diabetic-friendly cuisine can be both exotic and exciting.

Why This Recipe Works

  • Proper Tenderizing: The initial simmer with aromatics ensures the octopus is tender, not rubbery, while the grilling adds smoky depth.
  • Compound Butter Magic: The lemongrass-calamansi butter melts into an instant sauce, providing richness and complex flavor without flour-based thickeners.
  • Shirataki Transformation: The neutral-flavored shirataki rice becomes a flavor sponge for the coconut milk and aromatics, mimicking sticky rice texture without the carbs.
  • Balanced Macronutrients: The combination of lean protein from octopus, healthy fats from coconut and butter, and fiber from shirataki creates a satisfying meal that supports stable blood sugar.

Ingredients

Octopus

  • 2 lbs (900g) cleaned octopus (fresh or frozen and thawed)
  • 1 lemon, quartered
  • 3 bay leaves
  • 3 cloves garlic, smashed
  • 1 tsp black peppercorns
  • 1 tsp sea salt, plus more for seasoning
  • 2 tbsp olive oil

Lemongrass-Calamansi Butter

  • 6 tbsp unsalted butter, softened
  • 2 tbsp finely minced lemongrass (white part only)
  • 2 tsp calamansi juice (or 1 tsp lime juice + 1 tsp orange juice)
  • 1 tsp calamansi zest (or ½ tsp lime zest + ½ tsp orange zest)
  • 1 small red chili, seeds removed and finely minced
  • 1 clove garlic, finely minced
  • ¼ tsp sea salt
  • ¼ tsp freshly ground black pepper

Shirataki Coconut Sticky Rice

  • 4 packages (8 oz/226g each) shirataki rice
  • 1 tbsp coconut oil
  • 2 cloves garlic, minced
  • 1 stalk lemongrass, bruised and cut into 2-inch pieces
  • 1 pandan leaf, tied in a knot (optional)
  • ¾ cup full-fat coconut milk
  • 2 tbsp coconut cream
  • ¼ tsp sea salt
  • 2 tbsp chopped fresh cilantro for garnish

Directions

Prepare the Octopus

  1. Rinse the octopus thoroughly under cold water. If using a whole octopus, remove the beak and ink sac if not already cleaned.
  2. In a large pot, combine 3 quarts of water with lemon quarters, bay leaves, smashed garlic, peppercorns, and salt. Bring to a boil.
  3. Reduce heat to a gentle simmer and carefully add the octopus. Simmer uncovered for 30-45 minutes until tender but still with some resistance when pierced with a fork. The cooking time will vary depending on the size of the octopus.
  4. Remove the octopus from the cooking liquid and let it cool until it's comfortable to handle.
  5. Cut the octopus into serving pieces—tentacles separated and body cut into chunks.

Make the Lemongrass-Calamansi Butter

  1. In a small bowl, combine softened butter, minced lemongrass, calamansi juice and zest (or substitutes), minced chili, minced garlic, salt, and pepper.
  2. Mix thoroughly until all ingredients are well incorporated.
  3. Transfer the compound butter onto a piece of parchment paper or plastic wrap. Roll into a log shape, twist the ends to seal, and refrigerate until firm, about 30 minutes.

Prepare the Shirataki Coconut Sticky Rice

  1. Drain the shirataki rice in a colander and rinse thoroughly under cold water for 1-2 minutes to remove the packaging liquid.
  2. Bring a pot of water to a boil. Add the shirataki rice and boil for 2-3 minutes, then drain again.
  3. Place the shirataki rice in a dry skillet over medium heat and cook, stirring frequently, for 5-7 minutes until all moisture has evaporated and the rice makes a squeaking sound when stirred.
  4. Transfer the dried shirataki rice to a bowl and set aside.
  5. In the same skillet, heat coconut oil over medium heat. Add minced garlic and cook until fragrant, about 30 seconds.
  6. Add the dried shirataki rice, lemongrass pieces, and pandan leaf (if using). Stir-fry for 2 minutes.
  7. Pour in the coconut milk and coconut cream. Add salt and stir to combine.
  8. Reduce heat to low, cover, and simmer for 10-12 minutes until the liquid is mostly absorbed and the rice has a sticky consistency.
  9. Remove from heat, discard the lemongrass pieces and pandan leaf. Cover to keep warm while grilling the octopus.

Grill the Octopus

  1. Preheat a grill or grill pan to high heat.
  2. Pat the octopus pieces dry and toss with olive oil, salt, and pepper.
  3. Grill the octopus for 2-3 minutes per side until charred and crispy on the edges.

Serve

  1. Divide the shirataki coconut sticky rice among four plates.
  2. Arrange the grilled octopus pieces on top of the rice.
  3. Slice the chilled lemongrass-calamansi butter into rounds and place 1-2 rounds on top of the hot octopus so it begins to melt.
  4. Garnish with chopped cilantro and additional calamansi or lime wedges if desired.

Make-Ahead & Storage

  • Prep Ahead: The lemongrass-calamansi butter can be made up to 1 week ahead and stored in the refrigerator, or frozen for up to 1 month. The octopus can be simmered until tender up to 2 days ahead, then refrigerated until ready to grill.
  • Storage: Leftover grilled octopus can be refrigerated in an airtight container for up to 2 days. The shirataki coconut rice can be refrigerated separately for up to 3 days.
  • Reheating: Gently reheat the octopus in a skillet with a small amount of olive oil, or briefly on the grill. The shirataki rice can be reheated in a microwave or skillet with a splash of coconut milk to refresh it.
  • Not Recommended for Freezing: While the compound butter freezes well, neither the cooked octopus nor the shirataki rice maintain their texture well when frozen and thawed.

Blood Sugar Considerations

This Grilled Octopus with Shirataki Coconut Sticky Rice contains only 9g of carbohydrates per serving, with 4g of fiber resulting in just 5g net carbs. This is a dramatic reduction from traditional versions with sticky rice, which typically contain 65-80g of carbohydrates per serving.

The shirataki rice is made from glucomannan, a type of fiber that comes from the root of the konjac plant. This fiber passes through the digestive system largely intact, meaning it has minimal impact on blood sugar levels. The coconut milk and cream add richness and flavor without adding significant carbohydrates.

The protein content (30g) helps promote satiety and stable blood sugar, making this a filling meal that won't leave you hungry soon after eating. The healthy fats from the compound butter and coconut milk help slow digestion and prevent rapid glucose absorption, while also providing richness and flavor satisfaction.

Chef's Notes

  • Octopus Selection: Fresh octopus is ideal, but high-quality frozen octopus works well and is often pre-tenderized. If using frozen, thaw completely in the refrigerator before cooking.
  • Tenderizing Alternatives: If you're short on time, pressure cooking the octopus for 15-20 minutes with the same aromatics will yield similar tenderness.
  • Shirataki Tips: The key to good shirataki rice is thorough rinsing and dry-cooking to remove the characteristic odor before adding flavors. Don't skip these steps.
  • Butter Variations: The compound butter can be customized with different herbs like Thai basil or cilantro for variation.
  • Serving Suggestion: For those not monitoring carbohydrates, this dish pairs beautifully with traditional sticky rice or jasmine rice.
  • Vegetable Addition: For added nutrition and color, serve with a side of quick-pickled cucumber and radish salad dressed with a splash of calamansi juice.
  • No Grill Option: If you don't have access to a grill, you can achieve similar results by broiling the octopus for 3-4 minutes per side, or searing in a very hot cast-iron skillet.
