Why You’ll Love This Creamy Garlic Butter Shrimp Mashed Potatoes Recipe
Okay, real talk—this recipe has completely changed my weeknight dinner game. Here’s why I keep coming back to it:

- ✅ Comfort food with a Southern twist: The creamy mashed potatoes are your classic Southern staple, but adding garlic butter shrimp takes things up a notch. It’s like the best of both worlds.
- ✅ Quick to pull together: From peeling shrimp to plating takes about 30 minutes. I’ve literally made this while my toddler was napping (and stealing my utensils).
- ✅ Crowd-pleaser: I’ve served this at family dinners and potlucks, and every time someone asks for the recipe. It’s fancy enough for guests but easy enough for weeknight.

This dish makes me feel like I’m treating myself without the guilt. It’s the kind of Southern comfort food that warms you up inside and makes you want to linger at the table a little longer.
What Ingredients You’ll Need for Creamy Garlic Butter Shrimp Mashed Potatoes
Here’s what’s cool about this ingredient list: it’s straightforward, but each item plays a key role in making this dish sing. I always break it down so you know exactly why everything’s there.
- Large shrimp (1 pound / 450g), peeled and deveined — Fresh or thawed frozen works. I prefer medium-sized for the perfect bite. Don’t skip deveining, unless you like surprises.
- Russet or Yukon Gold potatoes (2 pounds / 900g), peeled and cubed — Yukon Gold gives a creamier texture, but Russets mash beautifully too. Pro tip: cut evenly for even cooking.
- Unsalted butter (6 tablespoons / 85g) — This is where the richness comes from. I always use unsalted so I can control seasoning better.
- Fresh garlic (4 cloves, minced) — Garlic makes everything better, right? Fresh over powdered every time.
- Heavy cream (¾ cup / 180ml) — For that silky mash. I’ve tried milk, but cream gives it the perfect richness.
- Whole milk (¼ cup / 60ml) — Mixed with cream for a lighter texture. You can swap with all cream if you want it extra indulgent.
- Salt and black pepper — To taste. I season the potatoes and shrimp separately for balanced flavor.
- Fresh parsley (2 tablespoons, chopped) — Adds color and a fresh pop. I keep a bunch on hand for finishing touches.
- Lemon juice (1 tablespoon) — Just a splash brightens the shrimp and cuts the richness beautifully.
Quick note: I always keep frozen shrimp in my freezer for nights when I need dinner fast. Thaw them in cold water for about 15 minutes, and they’re ready to go. Also, if you’re out of heavy cream, half-and-half works in a pinch.
Equipment Needed
You don’t need a fancy setup to pull this off—trust me, I’ve made it with the bare minimum.
- Large pot — For boiling potatoes. Mine’s got a dent from years ago, but it still does the job.
- Large skillet or frying pan — To cook the shrimp and garlic butter sauce. Non-stick helps, but cast iron works beautifully too.
- Potato masher or electric hand mixer — I use a hand masher because I like a little texture, but a mixer makes it ultra smooth.
- Colander — For draining potatoes quickly. If you don’t have one, a slotted spoon works too.
- Mixing bowls — For prepping shrimp and mixing ingredients.
- Measuring cups and spoons — Baking is chemistry, but for this, eyeballing works okay if you’re comfortable.
- Wooden spoon or silicone spatula — For stirring the shrimp sauce. I’m obsessed with my silicone spatulas—they’re my kitchen MVPs.
If you want to get fancy, a garlic press makes mincing garlic effortless, but mincing by hand works just fine. Also, a lemon squeezer is handy if you’re using fresh lemons.
How to Make Creamy Garlic Butter Shrimp Mashed Potatoes: Step-by-Step
- Boil the Potatoes (20 minutes)
Place peeled and cubed potatoes in a large pot and cover with cold water. Add a pinch of salt. Bring to a boil over high heat, then reduce to medium and simmer until potatoes are fork-tender—about 15-20 minutes. Drain well in a colander. - Mash the Potatoes (5 minutes)
Return the drained potatoes to the pot or a large bowl. Add 4 tablespoons (57g) of butter, heavy cream, whole milk, and a good pinch of salt and pepper. Mash with a potato masher or hand mixer until smooth and creamy. Taste and adjust seasoning. Keep warm. - Cook the Garlic Butter Shrimp (8-10 minutes)
While potatoes are boiling, heat a large skillet over medium heat. Add 2 tablespoons (28g) butter. Once melted and bubbling, add minced garlic and sauté until fragrant—about 30 seconds (don’t let it burn!). Add shrimp in a single layer. Season with salt and pepper. Cook shrimp for 2-3 minutes per side or until pink and opaque. - Add Lemon and Parsley (1 minute)
Squeeze fresh lemon juice over the shrimp and sprinkle chopped parsley. Stir to combine and turn off heat. - Plate and Serve
Spoon a generous mound of mashed potatoes onto plates and top with garlic butter shrimp. Drizzle any remaining garlic butter sauce from the skillet over the top for extra flavor. Garnish with more parsley if you’re feeling fancy.
Pro tip: If you want extra garlicky mashed potatoes, sauté a clove of garlic in butter before mashing it in. I do this when I want to really wow guests.
My Best Tips & Techniques for Perfect Creamy Garlic Butter Shrimp Mashed Potatoes
Alright, here’s where I share the stuff I wish someone told me the first time I made this:
- Don’t overcook the shrimp. They go from perfectly tender to rubbery in seconds. Keep an eye on the color change—they should be pink and just opaque.
- Use cold water to start boiling potatoes. This helps them cook evenly and prevents the outside from getting mushy before the inside is done.
- Butter temperature matters. Let your butter melt gently and don’t let the garlic brown too much or it turns bitter.
- Season in layers. Salt and pepper the shrimp, potatoes, and sauce separately. It makes the whole dish taste balanced instead of flat.
- Let potatoes dry after draining. Give them a minute in the hot pot with the lid off. This gets rid of extra moisture and keeps your mash fluffy.
- Fresh garlic beats jarred every time. I’ve tried garlic powder, but fresh just has that punch that makes this dish sing.
- Don’t skip the lemon juice. It brightens the buttery shrimp and stops the dish from feeling too heavy.
Also, I always prep shrimp and potatoes at the same time to save time. Multi-tasking in the kitchen is my jam.
Ways to Mix It Up
Once you nail the classic, these twists keep things interesting:
- Spicy Kick: Add a pinch of red pepper flakes to the garlic butter sauce. It adds a subtle heat that pairs wonderfully with the creamy potatoes.
- Cheesy Mash: Stir in ½ cup shredded sharp cheddar or parmesan into the mashed potatoes for an ultra-rich flavor.
- Herb Swap: Use fresh thyme or dill instead of parsley for a different herbaceous note.
- Cajun Style: Season shrimp with Cajun seasoning instead of plain salt and pepper. Adds that Southern flair that’s hard to beat.
- Veggie Boost: Stir in steamed broccoli florets or sautéed spinach into the mashed potatoes to sneak in some greens.
- Garlic Roasted Potatoes: Swap mashed potatoes for roasted garlic potatoes if you want texture contrast and a crispy edge.
- Make it Dairy-Free: Use olive oil instead of butter and coconut milk in place of cream. The flavor shifts but still delicious.
I’ve tried all these variations, and honestly, they’re all winners. The best part? You can customize this recipe to your mood or what’s in your fridge.
Serving Ideas & Storage
This creamy garlic butter shrimp mashed potatoes recipe is fantastic served warm, straight from the stove. I like slicing lemon wedges on the side for an extra zesty squeeze.
Pair it with a simple green salad or roasted veggies for a complete Southern-style dinner. It’s also amazing alongside sautéed green beans or collard greens for that homestyle vibe.
Got leftovers? No worries.
- Room temperature: Store in an airtight container for up to 2 days.
- Refrigerator: Keeps well for 3-4 days. Reheat gently in the microwave or on the stovetop with a splash of milk or cream to keep it creamy.
- Freezer: You can freeze mashed potatoes (without shrimp) for up to 3 months. Thaw overnight in the fridge and reheat. Shrimp doesn’t freeze as well cooked, so best to cook fresh when serving again.
Pro tip: When reheating, sprinkle a little water or broth on the mashed potatoes and cover loosely to avoid drying out. And if the shrimp get a little rubbery after reheating? Chop them up and toss into a salad or omelet for round two.

FAQs
Q: Can I use frozen shrimp for this recipe?
A: Absolutely! Just make sure to thaw them properly by soaking in cold water for about 15 minutes and patting dry before cooking. I keep frozen shrimp on hand for quick meals like this all the time.
Q: How do I know when the mashed potatoes are done?
A: When a fork easily pierces the potatoes and they’re tender all the way through, they’re ready. Overcooking can make them waterlogged, so keep an eye and start checking at 15 minutes.
Q: Can I make this recipe dairy-free?
A: Yes! Swap butter for olive oil or a dairy-free butter alternative and use coconut milk or almond milk in place of cream. The texture will be slightly different but still tasty.
Q: What can I substitute if I don’t have heavy cream?
A: Whole milk mixed with a tablespoon of melted butter works in a pinch. It won’t be quite as rich, but your mashed potatoes will still be creamy and delicious.
Q: Can I make this ahead of time?
A: You can prep the mashed potatoes a day ahead and reheat gently. I recommend cooking shrimp fresh to keep them tender. If you want to do it all ahead, cook shrimp last and warm everything before serving.
