What are the Best Potatoes for Mashed Potatoes?

I prefer using Russet potatoes in my blue cheese rosemary mashed potatoes. Russets are quite starchy, so they make for super creamy mashed potatoes.

If you would like to use another kind of potatoes, Yukon gold potatoes also work well for making this rosemary mashed potato recipe. You can also use a mix of russet and Yukon gold.

What Can I Substitute for Rosemary?

If you need other fresh herbs to substitute for the rosemary in these blue cheese rosemary mashed potatoes, thyme is the best option.

Can I Use Dried Rosemary?

Addition of fresh rosemary adds so much flavor and depth to this recipe for rosemary mashed potatoes. You can use dried rosemary, but it definitely wouldn’t be my first choice.

The rosemary flavor won’t be as fresh and herbal tasting. For dried rosemary use 1/4 – 1/2 teaspoon rather than the amount listed for fresh so the rosemary flavor isn’t overpowering.

Start with the smaller amount, and adjust for your personal preference.

How to Make Blue Cheese Rosemary Mashed Potatoes

It’s incredibly easy to make homemade mashed potatoes.

First, bring salted water to boil over high heat. Then, reduce heat to medium. Carefully place potatoes in the salted water and simmer the quartered and peeled potatoes over medium heat until fork tender.

Stir in a mixture of half and half, milk, chopped rosemary, and melted butter, as well as some of the gorgonzola. Taste and adjust seasonings as needed.

Spoon the blue cheese rosemary mashed potatoes into an oven-safe dish, then top with remaining gorgonzola and more melted butter.

Bake the blue cheese rosemary mashed potatoes until heated through and the cheese is soft. Garnish with rosemary sprigs.

How Long to Boil Potatoes for Mashed Potatoes

The peeled and quartered Russet potatoes will need to boil for roughly 20 to 30 minutes, or until fork tender.

Tips for Making the Best Rosemary Mashed Potatoes

Make sure to warm the half and half before stirring it into the blue cheese rosemary mashed potatoes. You don’t want the mashed potatoes to seize up and become clumpy by adding cold half and half.

Note that if you don’t have half and half on hand, you can also use whole milk. Just note that whole milk will make for less creamy mashed potatoes.

How to Get the Fluffiest Mashed Potatoes

One more quick tip on the mashing technique – invest in a Potato Ricer.

When you use a Potato Ricer, your potatoes will be fluffier and won’t develop a glue-y texture that over-mashed mashed potatoes can often develop.

You’ll be so happy with the results. Plus, it is kind of a cool kitchen gadget to use.

How to Keep Mashed Potatoes Warm

If you have space in your oven, you can keep these blue cheese rosemary mashed potatoes warm in the oven. Cover the mashed potatoes with foil to prevent them from drying out. Heat oven to 200 degrees F to keep them warm.

Alternately, you can keep mashed potatoes warm in a CrockPot or slow cooker that’s been set to the “warm” setting. Keep an eye on the mixture and stir in extra warmed milk or half and half if the potatoes ever look dry.

How to Reheat Mashed Potatoes

The best way to reheat mashed potatoes is in the oven.

You’ll want to use a baking dish covered with aluminum foil. You’ll likely need to add more butter and/or milk to loosen up the potatoes a bit.

Can You Freeze Mashed Potatoes?

Yes, very easily! Here’s how to freeze this rosemary mashed potato recipe:

1. Let them cool completely.
2. Then store the blue cheese rosemary mashed potatoes in a freezer bag.
3. When you’re ready to eat the frozen mashed potatoes, let them thaw in the fridge overnight.
4. Then, reheat them from frozen in a covered baking dish until they’re warmed through.
