How to Make Blue Cheese Mashed Potatoes Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F. This warm-up ensures your finishing bake will perfectly melt the cheese topping and give the dish a lovely, slightly crusted surface.
Step 2: Cook the Potatoes
Place the peeled and cubed russet potatoes in a large pot of boiling water. Let them cook for about 15 minutes until fork tender. This softness is key to getting creamy mashed potatoes with no lumps.
Step 3: Infuse the Butter
While the potatoes boil, melt the unsalted butter in a small skillet over medium heat. Add the crushed garlic, ground black pepper, steak seasoning, kosher salt, and chopped rosemary. Once melted, reduce the heat to low and let the flavors merge gently for 5 to 10 minutes. This step is what makes your mashed potatoes truly memorable by layering in complex tastes.
Step 4: Mash and Mix
Drain the cooked potatoes and return them to the pot on low heat. Use an electric hand mixer to mash them until smooth and creamy. Then, fold in the garlic rosemary butter and half of the blue cheese crumbles with a gentle hand, allowing the cheese to melt slightly into the warm potatoes.
Step 5: Bake and Finish
Spoon your luscious mashed potatoes into an oven-safe bowl or casserole dish. Sprinkle the remaining blue cheese evenly on top. Pop the dish into the oven and bake for 5 to 7 minutes. This short bake melts the cheese topping and gives it a light golden crust, turning the dish into an irresistible treat.

Make Ahead and Storage
Storing Leftovers
Leftover Blue Cheese Mashed Potatoes can be stored in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making them just as delightful, if not more, the next day.
Freezing
To freeze, cool the mashed potatoes completely, then transfer to a freezer-safe bag or container. They can be frozen for up to 2 months. Just remember that the texture may soften a bit after thawing.
Reheating
Reheat leftovers gently on the stove over low heat or in the microwave with a splash of milk or cream to restore creaminess. Give a good stir to evenly warm through and freshen up the flavors before serving.
FAQs
Can I use a different type of cheese instead of blue cheese?
Absolutely! While blue cheese gives this recipe its signature tang, crumbled feta or goat cheese can provide a milder but still flavorful twist if you prefer.
Is it necessary to bake the mashed potatoes after mixing in the cheese?
Baking helps melt the cheese on top and develops a slight crust that adds to the texture and presentation, but you can skip this step if you’re short on time, and the mashed potatoes will still taste delicious.
Can I make this recipe dairy-free?
For a dairy-free version, substitute the butter with your favorite plant-based spread and choose a dairy-free cheese alternative. Keep in mind the flavor profile will change, but it can still be tasty.
How do I prevent the mashed potatoes from becoming gluey?
Using starchy russet potatoes and mashing them gently helps avoid gluey textures. Also, adding warm butter and cheese allows for smoother incorporation without overworking the potatoes.
Can this recipe be doubled for a larger crowd?
Yes, this Blue Cheese Mashed Potatoes Recipe scales well. Just be sure to use a large enough pot for boiling and a big enough dish for baking to ensure even cooking and melting.

There’s something truly special about a dish that feels both decadent and approachable, and this Blue Cheese Mashed Potatoes Recipe hits that sweet spot perfectly.
