Cheesy Smashed Potato Bake is my kind of potato side dish: crispy edges, soft centers, and a garlic butter base that tastes like you actually tried.
The topping is what makes it stand out for me. It’s creamy from the sour cream and heavy cream, then you get that cheddar + Parmesan melt that turns the whole thing into a scoopable casserole.
I like this for holiday dinners, potlucks, or any night when I’m serving something simple like roast chicken and I want the side dish to do a little more work.
Why You’ll Love This Recipe
Crispy edges: Smashing the potatoes gives you all those rough bits that get browned and crunchy in the oven.
Garlic butter flavor: The butter and olive oil combo keeps the potatoes rich without feeling greasy, and the garlic actually comes through.
Real comfort food: The sour cream and heavy cream make the topping creamy and a little tangy, which is nice with all that cheese.
Easy to customize: Add bacon, swap in other cheeses, or keep it vegetarian and still end up with something solid.
Great for a big pan: A 9×13 dish feeds a group and it holds well on the table while you get everything else served.
Ingredients You’ll Need
Potatoes
- Baby Yukon Gold potatoes: These are my favorite here because they stay buttery and soft inside, but still crisp up nicely around the edges.
- Kosher salt: Salt the boiling water so the potatoes are seasoned all the way through, not just on top.
- Black pepper: I like a generous amount since it cuts through the richness of the cheese and cream.
Garlic butter and seasoning
- Unsalted butter: Melting it makes it easy to brush over every potato. Unsalted gives you more control since the cheese adds salt too.
- Olive oil: Helps the butter brown a little better in the oven and keeps the potatoes from drying out.
- Garlic: Fresh minced garlic is best here. Jarred works in a pinch, but it’s a little milder.
- Smoked paprika: Adds a subtle smoky note and helps with that nice roasted color on the potatoes.
- Salt: I like to taste and adjust after the butter mixture goes on, especially if you’re using bacon.
Cheesy topping
- Sharp cheddar cheese: Sharp is worth it here because the potatoes and cream can dull milder cheese. It keeps the flavor bold.
- Parmesan cheese: Adds that salty, nutty bite and helps the top brown. Pre-grated is fine, but freshly grated melts smoother.
- Sour cream: This is what gives the topping a tangy, “loaded potato” feel. Greek yogurt works too if that’s what you keep around.
- Heavy cream: Makes the topping pourable and helps the cheese melt into the cracks. Half and half works if you want it a little lighter.
- Bacon (optional): Totally optional, but it’s great if you want the full loaded potato thing. I like it crumbled pretty small so it spreads out.
- Green onions: Adds a fresh, sharp bite at the end. Chives work too.
- Fresh parsley (optional): Just a little sprinkle makes the pan look nicer and adds a clean, herby finish.
Recipe Instructions
- Heat the oven: Heat the oven to 425°F and grease a 9×13-inch baking dish.
- Boil the potatoes: Add the potatoes to a large pot and cover with cold water, then add 2 teaspoons salt. Bring to a boil and simmer until fork-tender, about 15 to 20 minutes.
- Drain and dry: Drain the potatoes well, then let them sit for about 5 minutes so the steam can dry them out a bit.
- Smash the potatoes: Spread the potatoes in the baking dish and smash each one to about 1/2-inch thick using a potato masher or the bottom of a glass.
- Mix the garlic butter: Stir together the melted butter, olive oil, minced garlic, and smoked paprika.
- Season the potatoes: Brush or spoon the garlic butter mixture over the smashed potatoes. Season with pepper and add a little extra salt if needed.
- Bake: Bake until the edges are crisp, about 20 to 25 minutes.
- Add the topping: Whisk the sour cream and heavy cream together, then spoon it over the potatoes. Top with cheddar, Parmesan, and bacon if using.
- Bake again: Bake until the cheese is melted and bubbling, about 10 to 15 minutes.
- Rest and finish: Let the dish rest for about 5 minutes, then top with green onions and parsley if you want.
Some of my tips!
This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.
Recipe Tips & Tricks
Let the potatoes steam-dry. Those few minutes after draining really matter. Drier potatoes crisp up better and don’t get watery under the topping.
Pick potatoes that are close in size. It keeps the boiling time simple, and you won’t end up with a few that are falling apart while others are still firm.
Don’t smash them too thin. About 1/2-inch is the sweet spot. If they’re too thin, the centers dry out before the edges get crisp.
Use convection if you’ve got it. Convection at the same temperature helps the rough edges brown faster and more evenly.
Grate your own cheese if you can. Bagged shredded cheese works, but freshly shredded melts smoother and bubbles better on top.
Make some touches!
There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.
Serving Suggestions
- Roast chicken: I love this next to a simple roast chicken or baked chicken thighs. It’s an easy dinner that still feels like a full spread.
- Steak or burgers: Serve it like a casserole-style alternative to fries. A little extra green onion on top is nice if you’re doing burgers.
- Green veggies: Something like roasted broccoli, green beans, or asparagus keeps the plate from feeling too heavy. I usually do a quick lemon squeeze on the vegetables.
- Salad: A chopped romaine salad with a sharp vinaigrette works really well here. Keep it simple and crunchy.
Save it for later
This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.
Storage and Make Ahead
Store leftovers covered in the fridge for up to 4 days. This holds up well, and the flavors are still great the next day.
Reheat individual portions in the microwave, or warm the whole dish in the oven until heated through. If you use the oven, cover with foil at first so the top doesn’t over-brown.
You can make this recipe ahead by boiling the potatoes earlier in the day, then draining and refrigerating them until you’re ready to smash and bake. I bring them closer to room temp first so they heat through more evenly.
If you want them to last longer, you can freeze individual portions or freeze the baked dish. Thaw in the fridge overnight before reheating.
A few quick answers
This section covers a few extra details that may help before you head to the recipe card.
Recipe FAQs
Can I use russet potatoes instead of baby Yukon Gold?
You can, but the texture is a little different. Russets are more fluffy and can fall apart when smashed, while Yukon Gold stays creamier and holds together better.
If you do use russets, I’d cut them into large chunks after boiling and be a little gentle when smashing.
Do I have to use heavy cream?
No. Half and half works, and even whole milk can work if that’s what you have, but the topping will be a little thinner and less rich.
Can I swap the sour cream?
Yes, plain Greek yogurt is an easy swap. I like full-fat Greek yogurt here because it stays creamy and doesn’t taste too sharp.
What cheeses work besides cheddar and Parmesan?
Mozzarella, Monterey Jack, or pepper jack are all good. I usually keep at least some sharp cheddar in the mix so the flavor doesn’t get too mild.
How do I keep the potatoes crispy under the topping?
The biggest thing is letting the potatoes steam-dry after boiling, then baking them until the edges are crisp before adding the sour cream and cheese. If you rush that first bake, the topping can soften everything.
