For Rosemary Garlic Mashed Potatoes you need:
- Russet Potatoes: Starchy potatoes are a go-to for mashed potatoes but waxy potatoes could work here as well.
- Garlic: Use fresh garlic for the best flavor! Mince the garlic or easily grate it so it incorporates well into the mashed potatoes.
- Rosemary: Rosemary is tasty but it could be overpowering. Add it in little bits and adjust the taste as needed.
- Whole milk: Milk adds creaminess and should be slightly heated before use.
- Butter: For buttery flavor in the potatoes and to top the mashed potatoes because there’s nothing like the look of pools of butter over potatoes.
- Salt and pepper: Black or white pepper would work. In fact, if you do not use white pepper, consider adding that to your spice collection for a more piquant flavor in meals.
- Garnishes: Minced parsley or chives sprinkled over mashed potatoes make for a tasty presentation.

Substitutions and Variations
- Potatoes: Consider using Yukon gold potatoes instead as they have a buttery flavor that already makes for tasty mashed potatoes from the get-go. You could also use half Russet and half Yukon gold potatoes.
- Cream: For richer mashed potatoes, substitute the milk with heavy cream or even evaporated milk (unsweetened).
- Cheese: Add cheddar cheese or any other cheese of your choice for cheesy mashed potatoes.
- Cream cheese: Consider adding cream cheese for a creamier mash and a hint of tang from the cream cheese. If you use any cheese, reduce the amount of salt used as cheese is already salty.
- More herbs: Add other herbs like thyme, dill, or oregano to your mashed potatoes.
- Bacon: Add bacon bits for more flavor and meatiness from the bacon.
- Chicken bouillon powder: For really tasty mashed potatoes, replace half of the salt with chicken bouillon powder. Taste and add more bouillon powder as needed.
Step By Step Process
Here is how to make Rosemary Garlic Mashed Potatoes in 4 easy steps:
Step 1: Peel and dice potatoes then boil until fork tender.
Step 2: Mash the potatoes using a potato masher then beat using an electric beater until smooth. Do not overmix.
Step 3: Pour melted butter with minced garlic and rosemary over the mashed potatoes.
Step 4: Season with salt and pepper and mix everything to combine. Taste to adjust seasoning.
Hint: mashing the potatoes with a potato masher breaks down the potatoes so they are easier to beat with an electric beater.

- Cold water: Start cooking the potatoes in cold water so they cook evenly.
- Warm milk: Slightly warm the milk before adding it to the mashed potatoes. Cold milk could prevent the potatoes from mashing smoothly if you’re going for smooth mashed potatoes.
- Good quality butter: For the best flavor, use good quality butter so the flavor of the butter adds to the mashed potatoes. Use European-style butter like Kerrygold for this.
- Beat potatoes while still hot: Mash and beat the potatoes while they are still hot, straight after draining them. Do not delay mashing so you can mash them easily and avoid lumps in the mashed potatoes.
- Use good potatoes: If the potatoes are starting to get bad, that will negatively impact the texture and taste of the mash.
- Bloom the spices: Simmering the garlic and rosemary in butter for a few minutes deepens their flavor, leading to really tasty mashed potatoes.
- Don’t overwhip! Overwhipped mashed potatoes have a gluey texture which is unpleasant.
- Cutting potatoes: Cutting the potatoes into 1-inch pieces helps them cook faster.
Reheating Mashed Potatoes
Microwave method: To reheat mashed potatoes, place them in the microwave to microwave for a few minutes then stir and serve.
Oven method: Cover the mashed potatoes and place them covered in the oven at 350 degrees Fahrenheit (180 degrees Celsius) to heat up until heated through.
Mashed potatoes go well with a number of spices and herbs including garlic, white or black pepper, parsley, dill, thyme, or basil.
A simple seasoning of salt and pepper will take mashed potatoes from bland to tasty! Add the seasoning in little bits then taste and adjust as needed. For more flavor, consider adding in some onion powder or garlic powder.
To make the best mashed potatoes, keep your potatoes hot before mashing, don’t add all the liquid at once, and taste as you make it to adjust seasoning.
