- Sour cream: Introduces a slight tang and deepens the overall flavor profile with a luscious creaminess.

How to Make Steakhouse-Style Garlic Mashed Potatoes Recipe
Step 1: Cook the Potatoes and Garlic
Begin by placing peeled and chunked russet potatoes along with whole, peeled garlic cloves into a large pot. Cover them with cold water and add a generous pinch of salt. Starting with cold water ensures even cooking. Bring the pot to a boil over medium-high heat, then reduce to a simmer. Let everything cook gently for 15 to 20 minutes until the potatoes are fork-tender and the garlic has softened into buttery sweetness.
Step 2: Drain and Mash
Once cooked, drain the pot thoroughly so no water dilutes the flavor. Return the potatoes and garlic to the pot and warm over low heat. This is the moment to gently mash everything together, letting the tender garlic mix fully with the fluffy potatoes. Warming the mixture a bit helps any added butter melt quickly and integrates the flavors beautifully.
Step 3: Add Butter, Milk, and Sour Cream
Gradually stir in cubed unsalted butter, allowing it to melt fully into the hot potatoes. Follow with the whole milk, which should be warmed slightly for best blending, and fold in the sour cream last. This combination creates that classic luscious creaminess that characterizes the best steakhouse mashed potatoes.
Step 4: Season to Taste
Finish your mash by seasoning it with salt and freshly ground black pepper, adjusting carefully to strike the perfect balance. Taste as you go — the right seasoning will bring out the best in every ingredient and elevate the whole dish into something truly memorable.

Garnishes
A sprinkle of chopped fresh chives or parsley adds a lovely pop of color and a fresh herbal note that cuts through the richness. You can also drizzle a little melted butter on top just before serving to enhance that inviting shine and buttery goodness.
Side Dishes
These garlic mashed potatoes shine alongside steak, roast chicken, grilled pork chops, or pan-seared salmon. They also serve as a perfect bed for rich gravies, caramelized onions, or sautéed mushrooms. Versatile and comforting, they fit seamlessly into both casual family dinners and special occasions.
Creative Ways to Present
For a fun twist, pipe the mashed potatoes onto plates or into a baking dish using a large star tip, then broil briefly for golden, crisp edges. Alternatively, scoop into small ramekins and top with cheese before baking for individual gratins that add a layer of indulgence.
Make Ahead and Storage
Storing Leftovers
If you have leftover mashed potatoes, store them in an airtight container in the refrigerator for up to 3 days. Before sealing, allow the mash to cool completely to prevent condensation and sogginess. When properly stored, the flavor and texture stay deliciously intact.
Freezing
While fresh is always best, you can freeze leftover garlic mashed potatoes for up to 2 months. Place them in freezer-safe containers or heavy-duty freezer bags, making sure to remove as much air as possible to prevent freezer burn. Thaw overnight in the refrigerator before reheating for best results.
Reheating
Reheat the mashed potatoes gently on the stovetop over low heat or in the microwave, adding a splash of milk or cream to revive their creamy texture. Stir frequently to promote even heating and avoid any drying out. You can also cover them with foil and warm in the oven.
FAQs
Can I use other types of potatoes for this recipe?
Russet potatoes are ideal for their high starch content, which yields fluffy mashed potatoes. Yukon Golds can work too, offering a creamier texture but with a slightly different flavor. Avoid waxy potatoes as they can produce a gluey result.
Is it necessary to use whole milk and sour cream?
Whole milk provides richness and smoothness, while sour cream adds a subtle tang that balances the flavors wonderfully. You can substitute heavy cream for a richer mash or use half-and-half, but the distinctive tang from sour cream enhances the steakhouse-style profile.
How can I make the garlic flavor more intense?
For a bolder garlic flavor, roasting the garlic cloves before adding them to the potatoes is a fantastic option. Roasted garlic is mellow, sweet, and concentrated, giving your mashed potatoes an irresistible depth.
Can this recipe be made vegan?
To make a vegan version, substitute the butter with a plant-based alternative and use oat milk or almond milk instead of whole milk. For the sour cream, try a vegan sour cream or simply use extra plant-based milk and a squeeze of lemon juice for a mild tang.
What is the best way to achieve perfectly smooth mashed potatoes?
Start by cooking potatoes until very tender, then mash them gently while warm. Using a potato masher rather than a food processor helps avoid a gummy texture. Gradually adding warm dairy ingredients ensures everything blends smoothly without clumping.
