My absolute favorite part of this dish is the garlic cream sauce I still remember the first time my kids tasted it because they requested more bread just to mop up every last drop It is so good you will want to drizzle it on veggies and chicken next time too

Storage Tips

Leftovers store beautifully in an airtight container in the fridge for up to two days Reheat mashed potatoes and shrimp gently on the stove with a splash more milk or cream to keep everything luscious Freezing is not recommended as the cream sauce may separate

Ingredient Substitutions

Use half and half in place of heavy cream for a lighter result For mashed potatoes you can sub Yukon Gold for russets or swap in cauliflower for a lower carb base Feel free to use pre-cooked shrimp if time is short just warm gently in the sauce so they do not get tough

Serving Suggestions

Pair with a crisp green salad and lemon vinaigrette for freshness Steamed green beans or broccolini make a lovely vegetable side If you want to stretch the meal further serve with crusty bread to soak up the extra sauce

Frequently Asked Questions

→ How do I prevent overcooking the shrimp?

Watch for the shrimp turning pink and curling. Remove them from the pan as soon as they're opaque and just cooked through for juicy, tender results.

→ What type of potatoes work best for this dish?

Russet or Yukon Gold potatoes yield the creamiest, fluffiest mashed potatoes thanks to their starch content and smooth texture.

→ Can I lighten the cream sauce?

Absolutely! Use half-and-half or whole milk instead of heavy cream for a lighter sauce, while still keeping it flavorful and creamy.

→ What’s the secret to smooth mashed potatoes?

Thoroughly drain and mash the potatoes while hot. For extra smooth results, use a potato ricer and incorporate warm milk and plenty of butter.

→ Are there ways to add vegetables?

Yes! Stir steamed broccoli or spinach into the mashed potatoes or serve them alongside for a more complete and balanced meal.

16 Fresh thyme sprigs

Instructions

Step 01

Place the peeled and cubed potatoes in a large pot. Cover with cold salted water and bring to a boil over high heat. Reduce to a gentle simmer and cook for approximately 15 minutes, until the potatoes are fork-tender. Drain thoroughly.

Step 02

Return the drained potatoes to the hot pot. Add the butter and warmed milk. Mash until completely smooth and creamy, ensuring a lump-free consistency. Season generously with salt, adjusting to taste. Cover to keep warm and fluffy.

Step 03

In a bowl, toss the peeled shrimp with olive oil, paprika, garlic powder, salt, and pepper until evenly coated. Heat a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 2–3 minutes per side, just until pink and curled. Transfer to a plate and keep warm.

Step 04

In the same skillet, melt butter over medium-low heat. Add the minced garlic and sauté for about 1 minute until fragrant but not browned. Pour in the heavy cream and bring to a gentle simmer.

Step 05

Stir in grated Parmesan and Dijon mustard if using, then season with salt and black pepper. Simmer for 3–5 minutes, stirring frequently, until the sauce thickens and coats the back of a spoon.

Step 06

Spoon a generous helping of mashed potatoes onto each plate. Top with cooked shrimp and drizzle with plenty of creamy garlic sauce. Garnish with fresh thyme sprigs immediately before serving.

Notes

  1. Pat shrimp thoroughly dry before seasoning to achieve a proper sear and maintain juiciness.
  2. Use a potato ricer for the creamiest mashed potatoes.
  3. For a lighter version, substitute half of the cream with milk or half-and-half.
  4. Add steamed broccoli or fresh spinach for a more complete meal.
