What Ingredients You Will Need

This savory garlic butter shrimp over creamy mash dinner is built on simple, wholesome ingredients that come together to create big flavors. Here’s what you’ll gather before you start cooking:

Shrimp: 1 pound (450g) medium or large shrimp, peeled and deveined (I like wild-caught if I can find it for better flavor and texture).
Butter: 4 tablespoons (60g) unsalted butter (use high-quality like Kerrygold for best richness).
Garlic: 4 cloves, minced (fresh garlic is key here—no shortcuts!)
Potatoes: 2 pounds (900g) Yukon Gold or Russet potatoes, peeled and cubed (Yukon Gold gives a creamier mash, Russet is fluffier).
Heavy Cream: ½ cup (120ml) for creamy mash (you can substitute half-and-half or whole milk if preferred).
Salt and Pepper: To taste (sea salt and freshly cracked black pepper work best).
Fresh Parsley: A handful, chopped for garnish (adds a fresh, herby pop).
Lemon Juice: 1 tablespoon, freshly squeezed (cuts through the richness with a bright note).
Olive Oil: 1 tablespoon (optional, helps cook shrimp evenly).

Pro tip: Look for firm, plump shrimp that smell fresh (not fishy). For the best mash texture, Yukon Gold potatoes are my go-to, but Russets are fine if you want a fluffier bite. If you want a dairy-free version, swap butter for vegan margarine and use coconut cream instead of heavy cream. It still tastes fantastic!

Equipment Needed

Large Pot: For boiling potatoes (a sturdy, heavy-bottomed pot works great).
Colander: To drain cooked potatoes easily.
Large Skillet or Sauté Pan: Non-stick or stainless steel pan to cook the shrimp and garlic butter sauce.
Potato Masher or Ricer: To mash potatoes smoothly (I prefer a ricer for ultra-creamy mash).
Measuring Cups and Spoons: For precise ingredient amounts.
Wooden Spoon or Silicone Spatula: For stirring without scratching your pans.
Knife and Cutting Board: For prepping garlic, parsley, and potatoes.

If you don’t have a potato masher, a sturdy fork can work in a pinch, though the texture might be a bit chunkier. A good non-stick skillet makes cooking shrimp easier and cleanup faster. I’ve found that a stainless steel pan gives a nice sear but requires a bit more attention so things don’t stick. For budget-friendly options, basic kitchen sets from your local store will do just fine.

Preparation Method

Prep the Potatoes: Start by peeling and cubing 2 pounds (900g) of Yukon Gold or Russet potatoes into 1-inch chunks. This ensures they cook evenly and quickly, about 15-20 minutes.
Boil the Potatoes: Place the potato chunks in a large pot and cover with cold water. Add a pinch of salt. Bring to a boil over medium-high heat and cook until potatoes are fork-tender, about 15-20 minutes. Test with a fork—it should slide in easily with no resistance.
Drain and Mash: Drain the potatoes in a colander and return them to the pot (off the heat). Add ½ cup (120ml) heavy cream and 2 tablespoons (30g) unsalted butter. Mash until smooth and creamy, adding salt and pepper to taste. If mash feels too thick, add a splash more cream or milk.
Prepare the Shrimp: While potatoes cook, pat 1 pound (450g) of shrimp dry with paper towels to ensure they sear well. Season lightly with salt and pepper.
Cook Garlic Butter Sauce: Heat 2 tablespoons (30g) unsalted butter and 1 tablespoon olive oil in a large skillet over medium heat. Add 4 cloves minced garlic and sauté for about 1 minute until fragrant—don’t let it brown or it’ll taste bitter.
Sauté Shrimp: Add seasoned shrimp to the skillet in a single layer. Cook for 2-3 minutes per side, until pink and opaque but not overcooked (shrimp cook fast, so watch carefully). Squeeze 1 tablespoon fresh lemon juice over shrimp and toss gently to coat.
Combine and Serve: Spoon creamy mashed potatoes onto plates, top with garlic butter shrimp, and sprinkle freshly chopped parsley over the dish. Serve immediately while warm.

Pro tip: If your shrimp start to curl tightly, that means they’re cooking too fast—lower the heat slightly next time to keep them tender. Also, letting garlic cook just until fragrant but not browned is key to avoiding bitterness. When mashing potatoes, don’t overwork them or they can get gluey; mash gently until just smooth.

Cooking Tips & Techniques

Getting this savory garlic butter shrimp over creamy mash dinner just right takes a few tricks I picked up over time. Here’s what I’ve learned:

Shrimp Cooking: Shrimp cook incredibly fast—usually 4-6 minutes total. Overcooking makes them rubbery, so keep a close eye and remove from heat as soon as they turn pink and curl slightly.
Garlic Flavor: Low and slow when sautéing garlic in butter is your friend. High heat burns garlic quickly, giving off a bitter taste that ruins the whole dish.
Mash Texture: Use Yukon Gold potatoes for creaminess or Russets for fluffiness. Avoid overmixing to prevent gluey mash. Adding warm cream or milk keeps mash silky.
Butter Quality: Good butter makes a difference—unsalted and high-quality (like European-style) butter adds richness without overpowering.
Multitasking: Boil potatoes while prepping shrimp and garlic to save time. This recipe comes together quickly once potatoes are cooked.

One time, I rushed and cooked shrimp on too high heat—total disaster with tough shrimp! Now I keep the heat moderate and move shrimp gently with a spatula. Also, I learned to always dry shrimp before cooking; it helps them sear instead of steam. These little details make the difference between good and great.

Variations & Adaptations

This recipe is super flexible, so feel free to adjust it to suit your taste or dietary needs:

Spicy Kick: Add red pepper flakes or a dash of cayenne to the garlic butter for a little heat.
Herb Swap: Try fresh thyme or dill instead of parsley for a different flavor profile.
Low-Carb Version: Serve garlic butter shrimp over cauliflower mash instead of potatoes for a keto-friendly option.
Dairy-Free: Use vegan butter or olive oil and substitute coconut cream or almond milk for the heavy cream in the mash.
Grilled Shrimp: For a smoky twist, grill shrimp marinated in garlic butter and lemon, then serve over the creamy mash.

I personally love adding a handful of sautéed spinach or mushrooms to the skillet with shrimp for extra veggies. It turns dinner into a more wholesome, colorful plate without complicating prep.

Serving & Storage Suggestions

Serve this savory garlic butter shrimp over creamy mash dinner hot, right off the stove, for the best flavor and texture. Garnish with fresh parsley and a lemon wedge on the side for a bright, fresh finish that complements the richness.

Pair it with a simple green salad or steamed veggies like asparagus or green beans to balance the meal. For drinks, a crisp white wine or sparkling water with lemon works beautifully.

Leftovers keep well in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat or microwave in short bursts, stirring occasionally. The mash may thicken when cold, so add a splash of cream or milk when reheating to bring back creaminess.

Fun fact: letting the shrimp sit in the garlic butter for a few minutes off the heat intensifies the flavor, so if you can, prepare it just before serving for maximum yum.
