This garlic shrimp over mashed potatoes pairs seared, paprika rubbed shrimp with a silky Parmesan cream sauce spooned over buttery Yukon Gold mash.
The whole meal is done in about 45 minutes with one pot and one skillet, and it serves 4. The sauce is built in the same pan that seared the shrimp, so it picks up all the browned garlic and paprika flavor left behind.

Why This Garlic Shrimp Over Mashed Potatoes Recipe Works
Yukon Gold potatoes boil to a naturally creamy texture, and warm milk plus butter mashed in while the potatoes are still hot gives a smooth base that holds up under the sauce.
The shrimp get a quick rub of paprika and garlic powder, then a hot sear for 2 to 3 minutes per side. Cooking them briefly keeps them tender, and removing them from the pan before the sauce stops them from overcooking.
The sauce is cream, garlic, Parmesan, and a small spoonful of Dijon mustard, simmered gently so it thickens without breaking. The Dijon adds a little tang that cuts through the richness.
Ingredients for Garlic Shrimp Over Mashed Potatoes
- 2 lb Yukon Gold potatoes, peeled and cubed
- 1 tablespoon salt, for the potato cooking water
- 1/2 cup warm whole milk
- 1/4 cup unsalted butter
- 1/4 teaspoon salt, for the mash
- 1 lb large shrimp, peeled and deveined
- 2 tablespoons olive oil
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1/4 teaspoon salt, for the shrimp
- 1/4 teaspoon black pepper
- 2 tablespoons unsalted butter
- 4 cloves garlic, minced
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1 teaspoon Dijon mustard
- 1 teaspoon fresh thyme leaves, for garnish
Potatoes: Cut them into even 1 inch cubes so they finish cooking at the same time, and start them in cold, salted water.
Shrimp: Pat the shrimp dry before seasoning so they sear instead of steam. Thaw frozen shrimp fully in the refrigerator first.
Heavy cream: Use heavy cream, which stays smooth when simmered. Half and half may thin out or split.
Parmesan: Grate it fresh from a wedge for the smoothest melt. Because it is salty, the sauce needs no added salt.
How to Make Garlic Shrimp Over Mashed Potatoes
1. Boil the potatoes. Cover the potatoes with cold water, add 1 tablespoon of salt, and boil for about 15 minutes until a fork slides in easily.
2. Mash. Drain well, return the potatoes to the pot, and mash with 1/4 cup butter, the warm milk, and 1/4 teaspoon of salt until smooth. Cover to keep warm.
3. Season the shrimp. Toss the shrimp with the olive oil, paprika, garlic powder, 1/4 teaspoon of salt, and the pepper.
4. Sear. Heat a large skillet over medium high heat and sear the shrimp for 2 to 3 minutes per side until pink and opaque. Move them to a plate.
5. Start the sauce. Lower the heat to medium, melt 2 tablespoons of butter in the same skillet, and cook the garlic for 30 to 60 seconds until fragrant.
6. Add the cream. Pour in the cream and simmer gently for 3 to 5 minutes, stirring, until it coats the back of a spoon. Do not let it boil hard.
7. Finish and plate. Take the pan off the heat and stir in the Parmesan and Dijon until smooth. Return the shrimp for 1 minute to warm through, then spoon the potatoes onto plates, top with shrimp and sauce, and finish with thyme.
How to Serve Garlic Shrimp Over Mashed Potatoes
Serve right away while the potatoes are hot and the sauce is glossy. A crisp green side balances the richness, such as air fryer asparagus or air fryer broccoli with Parmesan, and an easy green bean casserole makes it a seasonal worthy plate. Warm fluffy homemade dinner rolls are great for mopping up extra sauce.
How to Store and Reheat Garlic Shrimp Over Mashed Potatoes
Cool leftovers within 2 hours and refrigerate the shrimp, sauce, and potatoes in airtight containers for up to 2 days. Reheat gently on the stovetop or in the microwave with a splash of cream or milk until steaming hot, 165 degrees F. The sauce thickens in the refrigerator, so loosen it as you warm it. This dish does not freeze well because the cream sauce and potatoes change texture.
Tips and Variations for Garlic Shrimp Over Mashed Potatoes
Dry the shrimp. Moisture stops browning, so blot the shrimp with paper towels first.
Do not crowd the pan. Sear the shrimp in 2 batches if they do not fit in a single layer.
Watch the garlic. Minced garlic burns fast, so stir it for less than a minute before adding the cream.
Warm the milk. Cold milk cools the potatoes and makes them gluey.
Skip the food processor. Use a masher or ricer, because blades turn potatoes gummy.
Add heat. A pinch of red pepper flakes in the sauce gives it a gentle kick.
Brighten it. A squeeze of lemon over the shrimp at the table lifts the sauce.
Cook and chill safely. Texas A&M AgriLife Extension offers general food safety basics on cleaning, cooking, and chilling.
