How to Make Blue Cheese Mashed Potatoes with Garlic, Rosemary, and Steak Seasoning Recipe
Step 1: Prep and Boil the Potatoes
Start by peeling and cubing your russet potatoes to ensure they cook evenly. Place them into a large pot of boiling water and let them soften for about 15 minutes, or until you can easily pierce them with a fork. This base step sets the stage for irresistibly creamy mashed potatoes.
Step 2: Infuse Butter with Garlic, Rosemary, and Seasonings
While your potatoes are cooking, melt the butter in a small skillet over medium heat. Add the crushed garlic, ground black pepper, steak seasoning, kosher salt, and chopped rosemary to the butter. Once melted, reduce the heat to low and gently let the flavors meld for 5–10 minutes. This step lifts each ingredient’s essence, infusing the butter with deep, aromatic richness you’ll taste in every bite.
Step 3: Mash Potatoes and Combine
Drain the potatoes well and return them to the warm pot over low heat to evaporate any lingering moisture. Use an electric hand mixer to mash the potatoes until smooth and fluffy. Then, fold in half of the blue cheese crumbles along with the herb garlic butter. This combination creates creamy, decadently flavored mashed potatoes with just the right tang.
Step 4: Bake to Perfection
Transfer the mashed potatoes into an oven-safe bowl or casserole dish, and sprinkle the remaining blue cheese evenly over the top. Bake at 350°F for 5 to 7 minutes until the blue cheese on top is slightly melted and bubbly, adding a golden, inviting finish to your Blue Cheese Mashed Potatoes with Garlic, Rosemary, and Steak Seasoning Recipe.
How to Serve Blue Cheese Mashed Potatoes with Garlic, Rosemary, and Steak Seasoning Recipe
Garnishes
To elevate your presentation, sprinkle a few extra fresh rosemary leaves on top after baking or a light dusting of freshly cracked black pepper. For a pop of color, finely chopped chives or green onions offer a fresh contrast to the creamy potatoes and rich blue cheese.
Side Dishes
This recipe pairs wonderfully with hearty mains like grilled steak, roasted chicken, or pork chops. The robust flavors in the mashed potatoes complement savory proteins perfectly, balancing richness and adding a luxurious textural contrast to your meal.
Creative Ways to Present
For a fun twist, serve these Blue Cheese Mashed Potatoes with Garlic, Rosemary, and Steak Seasoning Recipe in individual ramekins topped with a sprig of rosemary. Or spread the mashed potatoes on a serving platter and create little peaks with a spoon to let the blue cheese melt highlight those rustic edges during baking.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator. These mashed potatoes will stay fresh for up to 3 days, making for an easy ready-to-serve side on your next meal.
Freezing
You can freeze leftover mashed potatoes by placing them in a freezer-safe container. They’ll keep well for about 2 months. When ready to enjoy, thaw overnight in the fridge before reheating to maintain the best texture.
Reheating
The best way to reheat is gently in the oven at 350°F, covered with foil to prevent drying out. Alternatively, use a microwave in short bursts, stirring in between to keep the blue cheese melting smoothly back into the potatoes.
FAQs
Can I use different types of potatoes?
Russet potatoes are ideal for this Blue Cheese Mashed Potatoes with Garlic, Rosemary, and Steak Seasoning Recipe because of their fluffy texture once cooked. Yukon Gold can work too but expect a creamier, denser mash.
What if I don’t have fresh rosemary?
Dried rosemary can be substituted but use about half the amount since it’s more concentrated. Fresh rosemary gives a brighter, more vibrant herbal note that really shines in this dish.
Can I make this recipe vegan or dairy-free?
To make it vegan, you can swap butter for plant-based margarine and use a dairy-free blue cheese alternative or omit the blue cheese altogether, though it will change the signature flavor.
Is the steak seasoning necessary?
While optional, steak seasoning adds a nice savory depth with its blend of spices. If unavailable, you can use a mix of garlic powder, paprika, and a bit of onion powder as a substitute.
How strong will the blue cheese flavor be?
The blue cheese flavor is pleasantly bold but balanced by the creamy mashed potatoes and butter. If you prefer a milder taste, start with less cheese and add more to suit your palate.
