Ingredients

For the Mashed Potatoes

• 2 lbs potatoes, peeled and cubed
• ½ cup warm milk
• ¼ cup butter
• Salt, to taste

For the Shrimp

• 1 lb large shrimp, peeled and deveined
• 2 tbsp olive oil
• 1 tsp paprika
• 1 tsp garlic powder
• Salt and black pepper, to taste

For the Creamy Garlic Sauce

• 2 tbsp butter
• 4 cloves garlic, minced
• 1 cup heavy cream
• ½ cup grated Parmesan cheese
• 1 tsp Dijon mustard (optional)
• Salt and pepper, to taste
• Fresh thyme leaves, for garnish

Step-by-Step Instructions

1. Bring a large pot of salted water to a boil. Add the peeled and cubed potatoes and cook for about 15 minutes, or until fork-tender and easily pierced.
2. Drain the potatoes well and return them to the pot while still hot. Add the butter and warm milk, then mash until smooth and creamy. Season with salt to taste, cover, and keep warm.
3. While the potatoes cook, pat the shrimp dry with paper towels. Place them in a bowl and toss with olive oil, paprika, garlic powder, salt, and black pepper until evenly coated.
4. Heat a large skillet over medium-high heat. Add the seasoned shrimp in a single layer and sear for 2–3 minutes per side, until pink, opaque, and lightly golden. Remove the shrimp from the skillet and set aside.
5. Reduce the heat to medium and, using the same skillet, add the butter. Once melted, add the minced garlic and sauté for about 30 seconds, stirring constantly until fragrant.
6. Pour in the heavy cream and bring it to a gentle simmer. Stir in the grated Parmesan cheese and Dijon mustard if using, whisking until the sauce is smooth and slightly thickened. Season with salt and pepper to taste.
7. Return the cooked shrimp to the skillet and gently stir to coat them in the creamy garlic sauce. Warm through for about 1 minute, then remove from heat.
8. To serve, spoon a generous portion of mashed potatoes onto each plate. Arrange the shrimp on top and drizzle with the creamy garlic sauce. Garnish with fresh thyme leaves and serve immediately.

Expert Tips for Best Results

Mash the potatoes while they are still hot. This helps create a smoother texture and allows the butter and milk to incorporate evenly.

Pat the shrimp dry before seasoning. Removing excess moisture helps them sear properly and prevents steaming in the pan.

Keep the garlic moving in the pan when making the sauce. Garlic cooks quickly, and stirring constantly prevents it from burning and turning bitter.

Simmer the sauce gently rather than boiling it. Lower heat keeps the cream smooth and prevents separation once the cheese is added.

Flavor Variations and Custom Ideas

• Use fresh parsley instead of thyme for a milder herb finish
• Add extra black pepper at the table for more warmth
• Serve with a simple green salad to balance the richness
• Pair with roasted vegetables for a more complete plate
• Spoon extra sauce over the potatoes for added comfort

Storage and Reheating

Store leftover shrimp, sauce, and mashed potatoes in separate airtight containers in the refrigerator for up to 2 days. Keeping components separate helps maintain their texture.

Reheat the potatoes gently in the microwave or on the stovetop with a splash of milk. Warm the shrimp and sauce over low heat, stirring occasionally, to avoid overcooking the shrimp.
