Why You’ll Love This Creamy Garlic Shrimp Over Mashed Potatoes

This recipe is the perfect mix of savory, creamy, and comforting. The shrimp are succulent and flavorful, while the mashed potatoes provide the ultimate soft and buttery base. It’s a complete meal in one bowl, with restaurant-quality taste made in your own kitchen. Plus, it only takes about 30 minutes from start to finish!

What Kind of Shrimp Should I Use?

I recommend using large or jumbo shrimp that are peeled and deveined for the best texture and ease of cooking. Fresh or frozen both work fine—just make sure to thaw frozen shrimp completely before cooking. Leaving the tails on can make for a prettier presentation, but for easier eating, feel free to remove them.

Options for Substitutions

• Dairy-Free Option: Use coconut cream or a dairy-free heavy cream alternative for the sauce, and replace butter in the mashed potatoes with olive oil or a vegan spread.
• Protein Swap: Not into shrimp? Try scallops, grilled chicken, or even pan-seared tofu for a vegetarian version.
• Herbs: Fresh parsley works beautifully, but basil or thyme can also bring a fresh pop of flavor.
• Potatoes: If you’re out of russets, Yukon Golds make for creamy, rich mashed potatoes too.

Ingredients for This Creamy Garlic Shrimp Over Mashed Potatoes

• Large Shrimp (peeled and deveined): The star of the dish, providing a juicy, meaty texture that pairs perfectly with the creamy sauce.
• Butter: Adds rich flavor and is used to sauté the shrimp and build the base of the sauce.
• Heavy Cream: Creates the velvety, luscious texture of the garlic sauce.
• Garlic (minced): The key aromatic that infuses the dish with deep, savory flavor.
• Parmesan Cheese (freshly grated): Helps thicken the sauce while adding a nutty, salty bite.
• Chicken Broth: Lightens the cream sauce and deepens the savory profile.
• Crushed Red Pepper Flakes: Introduces a mild heat that enhances the flavor without overpowering.
• Parsley (chopped): Fresh herbs brighten the sauce and add a pop of color.
• Salt and Black Pepper: Essential seasonings to balance and enhance all the flavors.
• Russet Potatoes (peeled and chopped): The foundation of the mash—fluffy, starchy, and perfect for absorbing the creamy sauce.
• Milk or Cream (for potatoes): Adds smoothness and richness to the mashed potatoes.
• Butter (for potatoes): Blends with the cream to make the potatoes ultra-creamy and flavorful.

Step 1: Prepare the Potatoes

Peel and chop the russet potatoes into equal-sized chunks. Place them in a large pot of salted water and bring to a boil. Cook until fork-tender, about 15 minutes. Drain and return to the pot. Add butter, cream or milk, salt, and pepper. Mash until smooth and fluffy, then cover to keep warm.

---

Step 2: Season and Sauté the Shrimp

Pat the shrimp dry with paper towels, then season lightly with salt and pepper. Melt butter in a large skillet over medium heat. Add the shrimp in a single layer and cook for 1–2 minutes per side until pink and opaque. Remove shrimp from the pan and set aside.

---

Step 3: Make the Creamy Garlic Sauce

In the same skillet, add a bit more butter if needed. Sauté the minced garlic for about 30 seconds until fragrant. Pour in the chicken broth and let it simmer for 2–3 minutes. Stir in heavy cream, grated parmesan, and red pepper flakes. Let the sauce simmer and thicken for 5–6 minutes, stirring occasionally.

---

Step 4: Combine Shrimp with the Sauce

Return the cooked shrimp to the skillet, tossing to coat evenly in the sauce. Let everything simmer together for another 2–3 minutes to meld the flavors. Add chopped parsley and taste for seasoning, adjusting with salt or pepper as needed.

---

Step 5: Serve Over Mashed Potatoes

Scoop generous portions of mashed potatoes into bowls or plates. Spoon the creamy garlic shrimp and sauce on top. Garnish with extra parsley and a sprinkle of parmesan if desired.

How Long to Prepare the Creamy Garlic Shrimp Over Mashed Potatoes

Prep Time: The preparation for this dish is quick and manageable. Peeling and chopping the potatoes will take about 10 minutes. If you’re using frozen shrimp, factor in another 10–15 minutes for thawing under cold water. Measuring out ingredients and mincing garlic can be done simultaneously as the potatoes boil.

Cook Time: Boiling the potatoes takes about 15 minutes. Meanwhile, cooking the shrimp and preparing the sauce adds another 15–20 minutes. All in all, you’re looking at around 30–35 minutes from start to plate, making this ideal for weeknight cooking without sacrificing flavor.

Tips for Perfect Creamy Garlic Shrimp Over Mashed Potatoes

• Use room temperature butter and cream for smooth incorporation.
• Don’t overcook the shrimp—they only need a minute or two per side.
• Add the parmesan off the heat if the sauce is too hot, to prevent clumping.
• Taste and adjust seasoning at each stage for the best flavor balance.
• Warm the plates before serving to keep the dish hot longer.

Watch Out for These Mistakes While Cooking

• Overboiling the potatoes: This can make them waterlogged and gluey instead of fluffy.
• Overcooking the shrimp: They turn rubbery fast—remove them as soon as they’re opaque.
• Using pre-shredded parmesan: It often contains anti-caking agents that affect the creaminess of the sauce.
• Letting the cream boil: Keep the heat at a gentle simmer to prevent curdling.
• Undersalting the potatoes: Mashed potatoes need enough salt to balance the rich sauce.

The slight char and earthiness of asparagus balance the richness of the meal.

Storage Instructions

Refrigeration: Store leftovers in an airtight container for up to 3 days. Keep the mashed potatoes and shrimp separately if possible, to prevent sogginess.

Reheating: Gently reheat in a skillet over low heat, adding a splash of cream or milk to loosen the sauce. Microwave is okay for a quick fix, but do it in short bursts to avoid overcooking the shrimp.

Freezing: Not ideal, as the creamy sauce can split upon thawing. However, mashed potatoes can be frozen separately for up to a month.

Frequently Asked Questions

What type of cream works best for the sauce?

Heavy cream or double cream works best because it creates a thick, luxurious texture and doesn’t curdle easily.

Can I use milk instead of cream?

You can, but the sauce will be thinner and less rich. Add a bit of flour to help it thicken if needed.

How do I prevent the mashed potatoes from getting gluey?

Avoid overmixing, and use a potato masher or ricer instead of a food processor.

Can I make this dish ahead of time?

You can make the mashed potatoes a day ahead and reheat gently. Cook the shrimp and sauce fresh for best results.

What wine pairs well with this dish?

A crisp white like Sauvignon Blanc or Chardonnay balances the creaminess and enhances the garlic and herb notes.
