Ingredients for Oven-Baked Mashed Potatoes
Here’s what you’ll need to make the creamiest oven-baked mashed potatoes:
- 6-8 medium potatoes – I like using Yukon Golds for their buttery texture, but russets work great too. Peel and cube them into even chunks.
- 1/2 cup water – This creates steam to cook the potatoes perfectly.
- 2 Tbsp. fat – Use whatever you’ve got—butter, margarine, mayo, or even a drizzle of olive oil for a lighter twist.
- Salt and pepper – To taste, of course. Don’t skimp here—seasoning makes all the difference!
That’s it—just four simple ingredients to get started. You probably have most of these in your kitchen already!
How to Make Oven-Baked Mashed Potatoes
Alright, let’s get to the fun part—making these dreamy, hands-off mashed potatoes! I love this method because it’s practically foolproof, but I’ve got a few tricks to share so yours turn out perfect every time.
First, preheat your oven to 350°F (no sneaky shortcuts here—this ensures even cooking). Grab a 9×13-inch baking dish and toss in those cubed potatoes. Pour in the water—just enough to create steam but not drown them (½ cup is the sweet spot). Cover the dish tightly with foil—I mean, crimp those edges like you’re sealing a treasure chest. This traps the steam so the potatoes cook up tender without drying out.
Slide the dish into the oven and let it work its magic for 1 to 1½ hours. Check at the 1-hour mark by poking a fork into a potato chunk—if it slides in effortlessly, they’re done. No rushing this step! Underbaked potatoes won’t mash smoothly, and nobody wants a lumpy surprise.
Now, here’s where the magic happens: don’t drain the water! That starchy liquid is your secret weapon for creaminess. Add your fat of choice (butter? mayo? a glug of olive oil?) and a generous pinch of salt and pepper. Mash it all together right in the pan—I use a potato masher for rustic texture, but an immersion blender gives you ultra-smooth results (just don’t over-blend or they’ll turn gluey). Taste and adjust seasoning—this is your moment to shine!
Tip: If the mash seems too thick, stir in a splash of warm milk or broth. Too thin? Let it sit uncovered in the oven for 5 minutes to thicken up. And hey—if you’re feeling fancy, now’s the time to fold in those add-ins (garlic, cheese, crispy bacon—you do you).

Tips for Perfect Oven-Baked Mashed Potatoes
After years of perfecting this recipe (and a few hilarious kitchen mishaps), here are my can’t-live-without tips:
- Pick your potatoes wisely – Yukon Golds give that buttery richness we all crave, while russets mash up extra fluffy. Just don’t use waxy red potatoes—they’ll never get creamy enough.
- Watch your water – That ½ cup measurement isn’t just a suggestion! Too much and you’ll end up with soup; too little and the potatoes won’t steam properly.
- Fat = flavor – Start with the 2 Tbsp, then add more to taste. The potatoes will tell you when they’re happy—you’ll see them go from dull to glorious as you mix.
- Mash hot – Don’t let them cool first. Hot potatoes absorb fats better and mash smoother with way less effort from you.
Trust me—follow these simple tricks and you’ll never go back to the old boiling method again!
Customizing Your Oven-Baked Mashed Potatoes
Now for the best part—making these oven-baked mashed potatoes your own! I love how versatile this recipe is—it’s like a blank canvas waiting for your personal touch. Here’s how I jazz mine up depending on my mood (or what’s lurking in my fridge):
- Garlic & herb – Stir in roasted garlic (or a spoonful of minced raw garlic for punch) with fresh chives or thyme.
- Cheesy bliss – Fold in shredded cheddar, Parmesan, or cream cheese for extra richness. The heat from the potatoes melts it into gooey perfection.
- Loaded – Top with crispy bacon bits, fried onions, and a dollop of sour cream—Sunday dinner just leveled up!
- Garden fresh – Leftover roasted veggies? Toss in some caramelized onions, sautéed mushrooms, or even chopped steamed broccoli.
Honestly? I’ve even stirred in a spoonful of pesto when I was feeling fancy. No rules—just deliciousness!
Serving Suggestions for Oven-Baked Mashed Potatoes
These oven-baked mashed potatoes are the ultimate team player at any meal! We love them piled next to juicy roast chicken on busy weeknights or smothered in gravy with Sunday pot roast. For holidays, they’re a must with glazed ham or turkey—just watch how fast they disappear from the serving bowl. And hey, don’t overlook them as a cozy base for saucy stews or grilled sausages. Honestly, they make everything better!
Storing and Reheating Oven-Baked Mashed Potatoes
Here’s the good news—these oven-baked mashed potatoes actually improve after sitting overnight (more flavor melding, yes please!). Store leftovers airtight in the fridge for 3-4 days. To reheat, splash in a little milk or broth and warm gently on the stove, stirring often. Microwaving works too—just cover and zap at 50% power to prevent drying out. Want to freeze? Skip dairy-heavy add-ins, portion into bags, and thaw overnight before reheating. Pro tip: Stirring in fresh butter when reheating brings back that just-made creaminess!
