Rinse shrimp under cold water and pat completely dry with paper towels.
In a small bowl, whisk together honey, minced garlic, soy sauce, olive oil, and cornstarch (if using). Set aside.
Heat a large skillet over medium-high heat. Add a drizzle of olive oil and let it heat until shimmering.
Add shrimp in a single layer. Season with salt and pepper. Cook 2–3 minutes until shrimp begin to turn pink and opaque.
Pour the honey garlic sauce over the shrimp. Toss to coat every piece evenly.
Reduce heat to medium-low. Simmer for 3–5 minutes until shrimp are fully cooked and sauce has thickened.
Remove from heat. Garnish with sliced green onions and sesame seeds. Serve immediately.
