Ingredients You’ll Need

This Cheesy Rosemary Mashed Potatoes Recipe blends classic ingredients with just the right herbs and cheeses to bring out the best flavors while keeping things straightforward. When shopping, look for good-quality fresh rosemary and freshly shredded cheeses for that extra punch.

• Potatoes: I use Yukon Gold or Russets for the perfect fluffy texture after boiling.
• Salt: Added to the boiling water to season potatoes from the inside out.
• Heavy cream: Warmed up for easier absorption into the mash, giving it a velvety feel.
• Unsalted butter: Melting this beforehand helps it blend smoothly.
• White cheddar cheese: Adds sharpness and depth; freshly grated is best.
• Mozzarella cheese: For that melty, gooey texture everyone loves.
• Fresh rosemary: Finely chopped to release all the herbaceous aroma.
• Ground black pepper: A subtle kick that complements the cheese and herbs.
• Panko breadcrumbs: Create that satisfying crunchy layer on top.
• Parmesan cheese: For the ultimate nutty, salty topping.

Variations

I love getting creative with this Cheesy Rosemary Mashed Potatoes Recipe, so don’t hesitate to make it your own! It’s my go-to comfort side, but changing it up with different cheeses or seasonings brings new excitement every time.

• Garlic butter version: When I first tried adding roasted garlic into the mash, it became an instant hit for my garlic-loving family.
• Herb twist: Swap rosemary for thyme or a combo of fresh herbs for a different herbal note that’s equally delicious.
• Dairy-free adaptation: Use plant-based cream and vegan cheese alternatives for a creamy texture without dairy.
• Spicy upgrade: A dash of smoked paprika or cayenne pepper adds subtle heat that wakes up the dish beautifully.

How to Make Cheesy Rosemary Mashed Potatoes Recipe

Step 1: Boil and Prep the Potatoes

Start by peeling and quartering your potatoes to ensure they cook evenly. Pop them in a large pot and cover with cold water — this helps cook them through without a mushy exterior. Add 2 tablespoons of salt once the water boils, then simmer for about 15 minutes or until a fork slides in easily. Draining well is key here, but I like to return the potatoes to the hot dry pot for a minute or two; it helps evaporate excess moisture and keeps your mash from being watery.

Step 2: Preheat and Prep Your Baking Dish

Turn your oven on to 375°F (190°C). Meanwhile, butter your favorite 9×13 inch casserole dish thoroughly. This little step saves you from sticky situations later and adds a lovely buttery flavor to the edges.

Step 3: Mash Potatoes to Creamy Perfection

For the smoothest mash, I always recommend using a potato ricer or food mill—but if you don’t have one, a sturdy masher works fine as long as you mash really well. Once mashed, stir in your warmed-heavy cream, melted butter, shredded white cheddar and mozzarella cheeses, fresh rosemary, and black pepper. The cheese will melt into a luscious mix that’s mouthwateringly good. Taste for seasoning, but since you added salt while boiling and have salty cheeses, you probably won’t need more.

Step 4: Assemble and Bake with the Crunchy Topping

Spoon your cheesy mash into the buttered casserole dish and even it out. Mix together the panko breadcrumbs and grated Parmesan cheese in a small bowl then sprinkle evenly on top. This topping is my favorite part—it bakes to a gorgeous golden crisp. Pop your dish in the oven for 30 minutes until bubbly and browned on top.

Step 5: Make Ahead & Freezing Tips

If you want to make this in advance, feel free to prepare the mashed potatoes and place them in the casserole dish, but don’t add the breadcrumb topping yet. Wrap it well and refrigerate. When you’re ready to bake, let it come to room temperature before adding the topping and baking as usual. For freezing, wrap tightly and thaw overnight in the fridge. Bring to room temp before baking with the topping. This trick prevents uneven cooking and soggy crust!

How to Serve Cheesy Rosemary Mashed Potatoes Recipe

Garnishes

When I serve this, I often sprinkle a little extra fresh chopped rosemary or cracked black pepper on top just before plating. It adds freshness and a pop of color, making the dish look as good as it tastes.

Side Dishes

This dish pairs beautifully with roast chicken, glazed ham, or a juicy steak. My family especially loves it alongside green beans almondine or roasted Brussels sprouts to balance out the richness.

Creative Ways to Present

For holiday dinners, I like to bake this casserole in individual ramekins—makes it feel extra special and personalized for each guest. Another fun idea: sprinkle a tiny bit of crispy bacon or crushed toasted walnuts on top for texture variety.

Make Ahead and Storage

Storing Leftovers

Leftover cheesy rosemary mashed potatoes keep well in an airtight container in the fridge for about 3-4 days. When I reheat them, the texture holds up nicely, especially if you add a splash of cream or milk to loosen it back up.

Freezing

I’ve frozen this casserole before with great results. Just wrap it tightly with plastic wrap and foil. When thawed properly in the fridge overnight, it tastes just as good as fresh after baking. Just remember to add the crispy topping fresh before baking for that crunch!

Reheating

Reheat leftovers in the oven at 350°F (175°C), covered with foil to keep moisture in, about 20 minutes or until warm through. Or for smaller servings, I gently microwave with a splash of cream, stirring halfway, to keep the mash creamy.
