Cooking is as much about the journey as it is about the destination. Let’s get started:

1. Start by boiling the potatoes in a large pot of salted water until they are tender, about 15-20 minutes. Drain and return them to the pot.
2. While the potatoes are cooking, melt 2 tablespoons of butter in a large skillet over medium heat. Add the shrimp, season with salt and pepper, and cook until pink, about 2-3 minutes per side. Remove shrimp and set aside.
3. In the same skillet, add the remaining butter and garlic. Sauté until fragrant, about 1 minute.
4. Pour in the chicken broth and heavy cream, stirring to combine. Let it simmer for about 5 minutes, allowing the sauce to thicken slightly.
5. Stir in the Parmesan cheese until melted and smooth. Return the shrimp to the skillet, tossing to coat them in the sauce. Sprinkle with fresh parsley.
6. To the potatoes, add milk, sour cream, and a pinch of salt. Mash until smooth and creamy.
7. Serve the shrimp and sauce over a generous scoop of mashed potatoes and enjoy!

Having cooked this dish countless times, I’ve learned that patience is key—let the sauce simmer to thicken just right, and you’ll be rewarded with a velvety finish.
