Heat vegetable oil in a large skillet over medium-high heat for about 2 minutes until hot.
Add the shrimp in a single layer and cook for 2–3 minutes on each side until pink and fully cooked.
Season the shrimp with salt and black pepper, then transfer to a plate and set aside.
In the same skillet, melt the butter and add minced garlic. Sauté for about 1 minute until fragrant.
Pour in the white grape juice or seafood broth and stir well for another minute.
Add heavy cream, Italian seasoning, and shredded cheese. Stir continuously and bring the sauce to a gentle simmer.
Reduce heat to medium and continue stirring until the creamy garlic shrimp sauce thickens to your preferred consistency.
Return the shrimp to the skillet and toss until fully coated in the creamy sauce.
Garnish with fresh parsley and serve immediately with pasta, rice, or mashed potatoes.
