Ingredients You’ll Need
The beauty of this recipe is how straightforward and essential the ingredients are. Each component plays a crucial role in building the rich flavor, creamy texture, and inviting appearance that make Rosemary Blue Cheese Mashed Potatoes so irresistible.
- 2 pounds russet potatoes peeled and cut into chunks: Russets are perfect for mashing thanks to their fluffy interior and mild flavor.
- 4 tablespoons unsalted butter: Adds silkiness and a rich, rounded taste to the mash.
- 1/2 cup whole milk warmed: Ensures the potatoes stay creamy and smooth without cooling down.
- 1/3 cup crumbled blue cheese: The star ingredient that brings a piquant, tangy punch to every spoonful.
- 2 teaspoons fresh rosemary finely chopped: Provides a fragrant, piney herb note that complements the blue cheese beautifully.
- 1/2 teaspoon salt: Enhances all the natural flavors without overpowering.
- 1/4 teaspoon black pepper: Adds just the right hint of warmth to balance the tanginess.
How to Make Rosemary Blue Cheese Mashed Potatoes
Step 1: Prepare and Cook the Potatoes
Start by peeling and cutting your russet potatoes into equal-sized chunks. Placing them in cold water with a pinch of salt and then bringing to a boil ensures even cooking and prevents the outside from becoming mushy before the inside is done. Let them cook for about 15 to 20 minutes until they’re fork-tender — soft enough to mash but still holding their shape.
Step 2: Drain and Mash
Drain the water thoroughly and return the hot potatoes to the pot. This step helps evaporate excess moisture, resulting in a thicker mash. Add the butter while the potatoes are warm so it melts perfectly, then start mashing until you get a creamy, smooth consistency. This part is where the magic texture begins to develop.
Step 3: Add Milk and Adjust Consistency
Warm the whole milk slightly and add it gradually to the potatoes, stirring gently as you go. This technique lets you control the creaminess level, whether you prefer a denser mash or something a bit more velvety and fluid. The warmth also keeps the potatoes from cooling down prematurely.
Step 4: Fold in Blue Cheese and Rosemary
Now for the exciting part — gently fold in the crumbled blue cheese and freshly chopped rosemary. The cheese will melt slightly from the warmth, releasing a beautiful tangy aroma that blends seamlessly with the earthy hint of rosemary. Mixing carefully ensures you keep some delightful texture from the cheese crumbles without overpowering the mash.
Step 5: Season and Serve
Finally, season with salt and black pepper to taste. This simple seasoning helps balance all the complex flavors and makes the dish truly shine. Serve these Rosemary Blue Cheese Mashed Potatoes piping hot alongside your favorite main dishes or enjoy them as a stellar comfort food treat on their own.
How to Serve Rosemary Blue Cheese Mashed Potatoes

Garnishes
To elevate your presentation, sprinkle a little extra fresh rosemary or some finely crumbled blue cheese on top right before serving. A drizzle of melted butter or a few chives can also add a touch of elegance and freshness that draws people in before they even take their first bite.
Side Dishes
These mashed potatoes are wonderfully versatile and complement a variety of dishes. Pair them with roasted chicken, juicy steak, or herb-crusted pork for a hearty meal. They also work beautifully alongside vegetable mains like grilled asparagus or sautéed mushrooms for a vegetarian feast that feels indulgent.
Creative Ways to Present
Try piping the Rosemary Blue Cheese Mashed Potatoes onto a platter using a large star tip for a stunning look, then broil quickly for a golden crust. Alternatively, serve portions in small ramekins topped with crispy rosemary leaves for an individual serving that’s both charming and delicious.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making reheated portions just as delightful as fresh.
Freezing
While mashed potatoes can be frozen, the presence of blue cheese means freezing might slightly change the texture. Still, if you want to freeze, place the cooled potatoes in a freezer-safe container and use within 1 month for the best flavor.
Reheating
Reheat gently on the stovetop over low heat or in the microwave, stirring occasionally. Add a splash of warmed milk or a little butter to restore creaminess and prevent drying out. Avoid high heat which can cause the cheese to separate.
FAQs
Can I use a different type of cheese instead of blue cheese?
Absolutely! While blue cheese gives this recipe its signature tang, you can experiment with other flavorful cheeses like goat cheese or gorgonzola for different nuances.
Is fresh rosemary necessary, or can I use dried rosemary?
Fresh rosemary offers a brighter, more vibrant flavor. Dried rosemary is stronger and more concentrated, so if you use it, reduce the quantity to about half a teaspoon to avoid overpowering the potatoes.
How can I make these mashed potatoes creamier?
For extra creaminess, substitute whole milk with half-and-half or cream. You can also add an extra tablespoon of butter to boost the richness.
Can this recipe be made vegan?
The blue cheese and butter are key for the flavor and texture, but for a vegan version, use dairy-free butter and a plant-based milk, and substitute blue cheese with a vegan cheese alternative that melts well.
Do these mashed potatoes work well for large gatherings?
Definitely! You can easily double or triple the ingredients and keep the mash warm in a slow cooker or oven-safe dish while you prepare the rest of your meal.
Final Thoughts
Rosemary Blue Cheese Mashed Potatoes are a wonderful way to transform a simple classic into an unforgettable side dish. The way the sharpness of blue cheese melds with the aromatic rosemary and silky potatoes is pure magic on a plate.
