With seven simple ingredients, they’re quick and easy to make, especially using the Instant Pot. Perfect for holidays or any meal, this recipe includes stovetop instructions, plus Whole30 and dairy-free options so everyone can enjoy them.
Mashed potatoes, or puré de papa as they are know in Spanish, were a regular side dish at our table growing up. They always paired perfectly with saucy dishes like Chile Verde con Queso, Pork in Salsa Verde, or Chile Colorado. My mom's mashed potatoes were simple yet comforting, the ideal way to soak up every bit of those flavorful sauces.
Now, as an adult, I love making mashed potatoes too, but with my own twist. Today's recipe is infused with garlic for extra flavor, and I use my Instant Pot to make this classic dish in record time with minimal effort.
The Instant Pot is especially convenient during the holidays when your stove may already be full with pots and pans of other delicious foods. And if you don’t own an Instant Pot, no worries—I’ve included stovetop directions along with plenty of tips and tricks to ensure your mashed potatoes turn out just right, whether you’re serving them for Thanksgiving or any occasion.

Ingredients & Substitutions
- Russet Potatoes: This type of potatoes make the fluffiest mashed potatoes. Russets are high in starch which result in a much lighter and fluffier mash. Yukon Gold Potatoes can be substituted and result in a creamy mash, but are much more dense so they won't come out as fluffy.
- Water: You will need plenty of water to cook the potatoes (whether in the Instant Pot or on the stovetop).
- Milk: I like using whole milk for rich and creamy results, but 2% will also work. For an even richer flavor, you can also use heavy cream and for a dairy-free alternative, use plain almond milk.
- Butter: I love the flavor of grass-fed butter, but use whichever butter you prefer. You can also use vegan butter for a dairy-free option or ghee for Whole30 or paleo.
- Garlic: You will need whole garlic cloves to get that true, amazing garlic taste.
- Salt and Pepper:
How to Make Garlic Mashed Potatoes
Instant Pot Method
1. Prepare the Potatoes: Wash and peel 2.5 pounds of russet potatoes. Cut each of the potatoes into 6 equal pieces.
2. Cook the Potatoes: Place the peeled and quartered potatoes in the Instant Pot with 6 cups of cold water, seal the valve, and pressure cook on high for 10 minutes. Once the cooking time is complete, quickly release the pressure, drain the potatoes thoroughly in a colander, and return them to the Instant Pot and set to warm.
3. Create Milk Mixture: In a small saucepan, combine milk, butter, and garlic cloves. Warm the mixture over medium-low heat for 5 minutes, stirring occasionally, until the butter melts and the garlic is fragrant. Remove from heat and set aside.
4. Season and Mash: Season the potatoes with salt and pepper, then mash them with a hand mixer or potato masher until smooth and fluffy. Remove the garlic cloves from the milk mixture and gently fold it into the mashed potatoes. Taste and adjust the seasoning as needed.
Stovetop Method
1. Prepare the Potatoes: Wash and peel 2.5 pounds of russet potatoes. Cut each of the potatoes in 6 equal pieces.
2. Cook the Potatoes: Place the potatoes in a large pot and cover with cold water. Bring to a boil, then reduce heat and simmer for 20 minutes, or until tender. Drain the potatoes completely.
3. Finish the Mashed Potatoes: Follow the same remaining steps listed above from creating the milk mixture, mashing the potatoes and seasoning.
Tips
- Mash Immediately: Mash the potatoes right away, while they're still hot, to avoid a gummy consistency.
- Evenly Sized: Cut your potatoes into evenly-sized pieces to ensure even cooking and prevent overcooking.
- Cold Water: Always use cold water to start the cooking process for consistently cooked potatoes.
- Drain Thoroughly: Drain your potatoes completely before mashing to ensure they come out fluffier.
- Classic Texture: For a classic, slightly chunky texture, use a potato masher. This traditional method allows more control over the consistency of your mashed potatoes.
- Fluffy Texture: For an extra fluffy texture, use a hand mixer. This technique, passed down from my mother-in-law, creates whipped mashed potatoes. However, be careful not to overmix, as this can lead to a sticky consistency.
