Heat vegetable oil in a large skillet over medium-high heat for about 2 minutes until hot.
Add shrimp in a single layer and sear for 2–3 minutes per side until pink and fully cooked.
Season the shrimp with salt and black pepper, then transfer to a plate.
In the same skillet, melt butter and sauté garlic for about 1 minute until fragrant.
Add white grape juice or seafood broth and stir well for another minute.
Stir in heavy cream, Italian seasoning, and shredded cheese.
Bring the sauce to a gentle simmer over medium heat, stirring continuously until thick and creamy.
Return the shrimp to the skillet and toss to coat in the creamy garlic sauce.
Garnish Creamy Garlic Shrimp with fresh parsley and serve immediately.
