How to Make This Quick Creamy Garlic Butter Shrimp With Mashed Potatoes
Step 1: Cook the Potatoes
Peel and cut the potatoes into even chunks. Place them in a large pot, cover with cold salted water, and bring to a boil.
Cook for 15–20 minutes, or until fork tender. Drain well, then return them to the warm pot for one minute to remove excess moisture.
Step 2: Make the Mashed Potatoes
Mash the potatoes until smooth. Add butter, warm milk, heavy cream, salt, and pepper.
Stir gently until creamy. Avoid overmixing, because too much stirring can make mashed potatoes gluey.

Step 3: Season the Shrimp
Pat the shrimp dry with paper towels. Season with paprika, Italian seasoning, salt, and black pepper.
Dry shrimp sear better and give you a richer flavor.
Step 4: Sear the Shrimp
Heat olive oil in a large skillet over medium-high heat. Add shrimp in a single layer.
Cook for 1–2 minutes per side, just until pink and opaque. Remove from the skillet and set aside.
Step 5: Make the Creamy Garlic Butter Sauce
Reduce heat to medium. Add butter to the same skillet, then stir in the garlic.
Cook for about 30 seconds until fragrant. Add chicken broth and scrape up the flavorful browned bits from the pan.
Pour in heavy cream and whisk until smooth. Add Parmesan cheese and Italian seasoning. Simmer gently for 3–5 minutes until the sauce thickens.
Step 6: Finish the Dish
Return the shrimp to the skillet and toss in the creamy garlic butter sauce.
Add lemon juice and parsley. Spoon mashed potatoes onto plates, then top with shrimp and extra sauce.
Best Tips for Perfect Creamy Garlic Butter Shrimp
Use large shrimp because they stay juicy and are harder to overcook.
Use fresh garlic instead of garlic powder for the best flavor.
Grate Parmesan fresh so the sauce melts smoothly.
Keep the sauce at a gentle simmer. Boiling cream can make it separate.
Taste before serving. Creamy dishes often need a final pinch of salt, pepper, or lemon juice to balance the richness.

Simple Storage and Reheating Tips
Store leftovers in airtight containers for up to 3 days.
For best results, store the shrimp and mashed potatoes separately. Reheat the potatoes with a splash of milk, and warm the shrimp sauce gently over low heat.
Avoid overheating shrimp in the microwave, because they can become rubbery.
The mashed potatoes can be frozen, but the cream sauce is best fresh because dairy sauces may separate after thawing.
FAQs About Creamy Garlic Butter Shrimp With Mashed Potatoes
Can I use frozen shrimp?
Yes, frozen shrimp work well. Thaw them completely and pat them dry before cooking so they sear instead of steam.
What potatoes are best for mashed potatoes?
Yukon Gold potatoes are best because they are naturally creamy and buttery. Russet potatoes also work if you prefer fluffier mashed potatoes.
Can I make this without heavy cream?
Yes. You can use half-and-half for a lighter sauce, but the sauce will be slightly thinner.
How do I keep shrimp from getting rubbery?
Cook shrimp only until pink and opaque. Remove them from the pan before making the sauce, then return them briefly at the end.
Can I serve this with rice instead?
Yes. Rice works well with the creamy garlic butter sauce. You can also serve it over pasta, cauliflower mash, or roasted potatoes.
What can I use instead of Parmesan?
Romano cheese works well. You can also use a small amount of cream cheese for a thicker sauce.
Can I make this ahead of time?
You can make the mashed potatoes ahead, but the shrimp tastes best cooked fresh. The sauce can be reheated gently with a splash of broth or cream.
