Ingredients Needed for Creamy Garlic Shrimp Over Mashed Potatoes

This creamy garlic shrimp recipe uses everyday ingredients that come together for a show-stopping meal. You probably have most of these already, and if not, I’ve got swaps that’ll save the day.

For the Mashed Potatoes:

• Russet or Yukon Gold potatoes, peeled and cut into chunks (2 pounds / 900g) (Yukon Golds are my fave for a buttery texture!)
• Unsalted butter (4 tablespoons / 56g), plus extra for serving (adds that restaurant-level creaminess)
• Whole milk or heavy cream (3/4 cup / 180ml) (whole milk works in a pinch, but cream makes them ultra-rich)
• Salt (1 teaspoon) (to highlight all the flavors—don’t skip it)
• Black pepper (1/2 teaspoon) (freshly ground is best)

For the Creamy Garlic Shrimp:

• Large shrimp, peeled and deveined (1 pound / 450g) (fresh or thawed frozen; I like wild-caught for best flavor)
• Olive oil (2 tablespoons / 30ml) (for sautéing; use butter if you want even more richness)
• Garlic cloves, minced (4 cloves) (use more or less depending on your garlic love—you do you!)
• Heavy cream (1 cup / 240ml) (creates that luscious sauce)
• Parmesan cheese, grated (1/2 cup / 50g) (adds depth and helps thicken the sauce)
• Chicken or seafood broth (1/2 cup / 120ml) (can substitute with vegetable broth if needed)
• Lemon juice (2 teaspoons / 10ml) (brightens everything up)
• Salt and black pepper (to taste)
• Fresh parsley, chopped (2 tablespoons) (for garnish and a pop of color)

Optional Add-Ons & Substitutions:

• Pinch of red pepper flakes (for a little kick—my family loves this)
• Use half-and-half instead of heavy cream for a lighter sauce
• Swap Parmesan with Grana Padano or Pecorino Romano if you like more tang
• Try sweet potatoes in place of regular potatoes for a slightly sweet base
• Dairy-free alternatives: use oat milk and vegan butter for the mash, coconut cream in the sauce
• Gluten-free: this recipe is naturally gluten-free—just check your broth and cheese labels!

I usually stick with fresh garlic, but jarred minced garlic works in a pinch. And if you’re feeling fancy, a splash of dry white wine in the sauce is a game-changer. You’ll see—these ingredients make creamy garlic shrimp over mashed potatoes taste like pure comfort on a plate.

Equipment Needed

You don’t need a commercial kitchen to whip up this creamy garlic shrimp recipe. Here’s what I use every time:

• Large pot (for boiling potatoes—any sturdy pot will do)
• Colander (for draining potatoes)
• Potato masher or hand mixer (masher for rustic texture, mixer for super smooth)
• Large skillet or sauté pan (for the shrimp and sauce; nonstick or stainless steel works)
• Wooden spoon or silicone spatula (for stirring the sauce—makes cleanup easy)
• Measuring cups and spoons (accuracy matters—don’t eyeball the cream!)
• Small bowl (for mixing lemon juice or prepping garlic)

If you don’t have a potato masher, use a fork or whisk—just takes a little more elbow grease. I used to make mashed potatoes with a basic hand mixer, and honestly, it works great for super fluffy results. For budget-friendly options, I love the OXO potato masher and Lodge cast iron skillet (they last forever). After cooking, I always rinse my skillet right away—shrimp residue can be stubborn if it sits. Trust me, these tools make this creamy garlic shrimp recipe come together easily.

Preparation Method

Ready to get cooking? Here’s the step-by-step guide to the ultimate creamy garlic shrimp over mashed potatoes. I’ll walk you through each part, so you can nail it—even on your first try!

Step 1: Prep the Potatoes (10 minutes)

1. Peel and cut 2 pounds (900g) of potatoes into roughly equal chunks—this helps them cook evenly.
2. Place potatoes in a large pot, cover with cold water, and add a generous pinch of salt.
3. Bring to a boil over high heat, then reduce to medium and simmer until potatoes are fork-tender (about 15-20 minutes).

Step 2: Make the Mashed Potatoes (5 minutes)

1. Drain potatoes in a colander, then return them to the pot.
2. Add 4 tablespoons (56g) unsalted butter and 3/4 cup (180ml) whole milk or heavy cream.
3. Mash with a potato masher or beat with a hand mixer until silky smooth. (If you like lumps, mash by hand—no shame!)
4. Season with 1 teaspoon salt and 1/2 teaspoon black pepper. Taste and adjust if needed. Cover to keep warm.

Step 3: Prepare the Shrimp (5 minutes)

1. Pat 1 pound (450g) peeled and deveined shrimp dry with paper towels. This helps them sear nicely.
2. Season lightly with salt and black pepper.

Step 4: Cook the Shrimp (5 minutes)

1. Heat 2 tablespoons (30ml) olive oil in a large skillet over medium-high heat.
2. Add shrimp in a single layer. Cook for 1-2 minutes per side until pink and opaque (don’t overcook—they go rubbery fast!).
3. Transfer shrimp to a plate and set aside.

Step 5: Make the Garlic Cream Sauce (7 minutes)

1. Reduce heat to medium. Add minced garlic (4 cloves) to the skillet. Sauté for 30 seconds—just until fragrant, not browned.
2. Pour in 1/2 cup (120ml) chicken or seafood broth. Scrape up any browned bits (that’s flavor!).
3. Stir in 1 cup (240ml) heavy cream and 1/2 cup (50g) grated Parmesan cheese. Cook, stirring, until the sauce thickens slightly (about 3 minutes).
4. Add 2 teaspoons (10ml) lemon juice for brightness. Taste and adjust seasoning.
5. If you want a thinner sauce, add a splash more broth or milk. Too thick? Just whisk in a little extra cream.

Step 6: Combine Shrimp & Sauce (2 minutes)

1. Return shrimp to the skillet. Toss gently to coat in the creamy garlic sauce. Heat through for 1 minute—don’t boil, or shrimp’ll toughen.
2. Sprinkle with chopped parsley for color and freshness.

Step 7: Serve (3 minutes)

1. Spoon mashed potatoes onto plates or into bowls. Top generously with creamy garlic shrimp.
2. Drizzle extra sauce over everything. Garnish with more parsley or a pinch of Parmesan.
3. Serve immediately! (The potatoes will soak up the sauce and get even better after a few minutes.)

Troubleshooting tips: If your sauce separates, whisk in a splash of cold cream off the heat. If shrimp look tough, they’re overcooked—next time, pull them off as soon as they turn pink. The mashed potatoes should be soft and fluffy, not gluey—don’t over-mix! Sensory cues: the shrimp should smell sweet, the sauce savory and garlicky, and the potatoes buttery with a hint of earthiness.

Efficiency tip: Start boiling your potatoes before prepping the shrimp. While potatoes cook, you can prepare the shrimp and sauce—makes dinner come together fast!

Cooking Tips & Techniques

Here’s where experience makes all the difference. After making creamy garlic shrimp over mashed potatoes more times than I can admit, these are my top tricks:

• Shrimp Size Matters: Large shrimp (16-20 count) work best—they stay juicy and don’t shrink to nothing. If you use smaller, cut back the cooking time even more.
• Don’t Overcook Shrimp: Shrimp cook fast. As soon as they turn pink and curl, get them out of the pan. Overcooked shrimp go chewy—learned that the hard way!
• Layer Flavors: Sauté garlic gently—if it burns, the whole sauce turns bitter. Keep heat at medium, and stir often.
• Whip, Don’t Mash (for potatoes): For super-smooth mashed potatoes, use a hand mixer. For chunky, rustic style, stick with a masher. Just don’t overwork the potatoes or they’ll get gluey.
• Deglaze the Pan: After cooking the shrimp, scraping up the browned bits with broth adds incredible depth to the sauce. Don’t skip this step—it’s where the magic happens!
• Timing is Everything: Start the potatoes first, and prep shrimp while they boil. Multitasking here saves at least 10 minutes.
• Taste As You Go: Seasoning at every stage keeps flavors balanced—adjust salt, pepper, and lemon to suit your taste.
• Consistency Check: Sauce should coat the back of a spoon, not runny nor clumpy. If it gets too thick, loosen with broth or milk.

I’ve had my fair share of bland shrimp and watery potatoes—usually because I rushed or skipped tasting. Give yourself permission to tweak as you go; that’s how you’ll get a dinner that truly shines. And hey, if the sauce breaks, whisk in a bit of cold cream—it usually fixes things!

Variations & Adaptations

This creamy garlic shrimp recipe is super flexible—here are my favorite ways to switch things up:

• Dairy-Free: Use oat milk and vegan butter for mashed potatoes, and coconut cream for the sauce. It’s not identical, but still pretty tasty!
• Low-Carb: Swap out potatoes for mashed cauliflower. Same technique, but way fewer carbs. I do this when I’m watching my carb intake—it’s surprisingly good!
• Spicy Kick: Add a pinch of red pepper flakes or a dash of cayenne to the sauce for a little heat. My husband swears by this version.
• Seasonal Swap: In summer, I toss in a handful of fresh spinach or asparagus with the shrimp. Adds color and a veggie boost.
• Different Cooking Methods: Grill the shrimp for a smoky flavor, then toss in the cream sauce. Or use an air fryer—shrimp cook in just a couple minutes!
• Allergen Substitutions: Use vegan Parmesan if you’re dairy-free, and check that your broth is allergen-safe.
• Personal Twist: Sometimes I add a splash of white wine to the sauce for extra depth. If you try this, let it reduce for a minute before adding cream.

Don’t be afraid to mix and match—this creamy garlic shrimp over mashed potatoes recipe is all about making it your own. Whether you’re cooking for dietary needs or just want something new, there’s a version that’ll work for you.

Serving & Storage Suggestions

This creamy garlic shrimp recipe looks gorgeous when served right out of the skillet over fluffy mashed potatoes. Here’s how I like to present and store it:

• Serving Temperature: Serve hot, right after combining the shrimp and sauce. The potatoes absorb the cream and get even better as they sit.
• Presentation: Spoon mashed potatoes into a shallow bowl, pile shrimp on top, and drizzle with extra sauce. Garnish with parsley and a lemon wedge.
• Complementary Sides: Pair with a crisp green salad, steamed broccoli, or buttery garlic bread. A glass of chilled white wine works wonders here!
• Storage: Store leftovers in an airtight container in the fridge for up to 2 days. The potatoes and shrimp reheat well—just don’t microwave too long, or shrimp can toughen.
• Freezer Tips: Mashed potatoes freeze well on their own (up to 1 month). Shrimp in cream sauce can be frozen, but the texture changes—so I rarely do it.
• Reheating: Gently reheat in a skillet over low heat, adding a splash of cream or milk to loosen the sauce. Stir often to avoid overcooking the shrimp.
• Flavor Note: Leftovers actually taste even better the next day as the garlic and cream meld. Just add a little fresh parsley to perk things back up.

This creamy garlic shrimp over mashed potatoes is best enjoyed fresh, but it’s forgiving if you need to prep ahead. Perfect for meal-prep lunches or a quick reheat dinner!
