Total time: 40 min
Cuisine: American
Ingredients: 2 pounds baby red potatoes; 1/2 cup unsalted butter melted; 1/2 cup grated Parmesan cheese; 3 cloves garlic minced; 1 teaspoon kosher salt; 1/2 teaspoon freshly ground black pepper; 1 teaspoon Italian seasoning; 1/2 teaspoon smoked paprika; 1/4 teaspoon red pepper flakes optional; 2 tablespoons chopped fresh parsley

If you’re the kind of person who could happily make a whole meal out of potatoes (hi, same), these Butter Swim Parmesan Roasted Potatoes are about to become your new obsession. Baby red potatoes are nestled into a shallow pool of garlicky melted butter, showered with Parmesan and spices, then roasted until their skins blister and the bottoms turn golden and crisp.

The best part is that all that buttery goodness doesn’t just disappear—it caramelizes on the pan and clings to every bite. The inside of each potato stays fluffy and tender, while the outside develops a salty, cheesy crust that tastes like the best steakhouse side dish, but you made it at home with one pan and almost no effort.

Why You’ll Love These Butter Swim Parmesan Roasted Potatoes

These potatoes deliver big-time comfort with almost zero prep. You’re basically letting the oven do the work while you handle the rest of dinner (or just pour yourself a drink and call it multitasking). No parboiling, no fancy knife work—just toss, roast, and admire the crispy edges.

They’re also wildly versatile. Serve them with Sunday roast, weeknight chicken, summer grilled steak, or a simple salad when you’re craving something cozy. Because they’re baked in butter, they feel a little extra—perfect for holidays and dinner parties—but they’re easy enough for an ordinary Tuesday.

What Potatoes Work Best for Butter Swim Parmesan Roasted Potatoes?

For this recipe, I love using small red baby potatoes. They hold their shape in the heat, their skins crisp up beautifully, and the centers stay creamy instead of falling apart. If some are a bit larger, you can cut those in half so everything roasts evenly.

You can swap in baby gold potatoes or small Yukon golds if that’s what you have on hand. Just keep the pieces about the same size so they cook at the same rate. Russets will work in a pinch, but they’re more starchy and won’t have quite the same silky texture inside.

Whatever potato you choose, make sure they’re dry before they hit the pan so that butter and Parmesan can cling to the surface instead of steaming off.

Ingredients for the Butter Swim Parmesan Roasted Potatoes

Before you grab a sheet pan, let’s talk about what each ingredient is doing here. Even though the list is short, every piece earns its place and builds flavor in the pan.

Baby red potatoes – Their thin skins and creamy centers are perfect for soaking up butter while staying tender and bite-sized.
Unsalted butter – This is the “swim” part: it creates a shallow buttery bath that crisps the bottoms of the potatoes and carries all the garlic and spices.
Parmesan cheese – Grated Parmesan melts into the butter and roasts into a salty, nutty crust on the potatoes and the pan.
Garlic – Fresh minced garlic perfumes the butter and gives that classic steakhouse roasted potato flavor.
Kosher salt – Seasons the potatoes all the way through and balances the richness of the butter and cheese.
Black pepper – Adds gentle heat and a little bite against the creamy potatoes.
Italian seasoning – A mix of herbs that brings some brightness and depth without needing multiple jars.
Smoked paprika – Adds a warm, smoky note and helps the potatoes get that gorgeous, deep golden color.
Red pepper flakes – Totally optional, but they give just enough heat to cut through the richness.
Fresh parsley – Sprinkled on at the end for a pop of freshness and color.

How To Make the Butter Swim Parmesan Roasted Potatoes

Once everything is prepped, this recipe is mostly hands-off oven time. The butter does the hard work of crisping the potatoes while you finish the rest of your meal.

Step 1: Prep the Pan and Potatoes

Preheat your oven to 425°F (220°C). Grab a large, rimmed sheet pan—metal works best for browning—and if it tends to stick, give it a light mist of cooking spray. Rinse the baby red potatoes, pat them very dry with a clean towel, and trim any rough spots. If a few potatoes are noticeably bigger than the rest, cut them in half so everything cooks at the same pace.

Step 2: Make the Garlic Butter Parmesan Bath

In a small saucepan or microwave-safe bowl, melt the butter until just liquid. Stir in the minced garlic, kosher salt, black pepper, Italian seasoning, smoked paprika, red pepper flakes if you’re using them, and about half of the grated Parmesan. This turns into the most fragrant, savory butter you’ll ever want to pour on potatoes.

Pour the butter mixture onto the sheet pan and tilt it around so the entire bottom is coated in an even layer.

Step 3: Nestle the Potatoes in the Butter

Arrange the potatoes on the pan in a single layer so each one has its own little spot in the butter. Place cut sides down if you’ve halved any—this is how you get those extra crispy, caramelized bottoms. Sprinkle the remaining Parmesan evenly over the tops of the potatoes.

Step 4: Roast Until Crispy and Golden

Slide the pan into the oven and roast for about 25–30 minutes, or until the potatoes are fork-tender and the bottoms are deeply golden. If you’d like them extra crisp, you can switch the oven to broil for the last 2–3 minutes—just keep a close eye so they don’t tip over into burnt territory.

As they roast, the butter will bubble and brown around the potatoes, creating little pools of garlic-Parmesan goodness.

Step 5: Finish and Serve

Once the potatoes are done, remove the pan from the oven and let everything sit for a couple of minutes so the butter settles. Use a spatula to gently loosen any crispy Parmesan bits from the pan and toss them back over the potatoes.

Transfer the potatoes to a serving dish (or serve straight from the pan for a more casual vibe), spoon some of the buttery pan sauce over the top, and finish with fresh parsley and a final sprinkle of Parmesan if you like.

Serving and Storing Butter Swim Parmesan Roasted Potatoes

This recipe comfortably serves 4 people as a generous side dish, or up to 6 if you’re serving it alongside several other dishes on a holiday table. The potatoes come to the table sizzling, with crispy Parmesan edges that make them feel special enough for guests but familiar enough that even picky eaters will dig in.

If you have leftovers, let them cool completely before transferring to an airtight container. They’ll keep in the fridge for up to 3–4 days. To reheat, spread them on a sheet pan and warm in a 400°F oven for about 10 minutes until hot and re-crisped, or use an air fryer for a few minutes to bring back that freshly roasted texture. The microwave will warm them, but you’ll lose some of the crispiness.

These potatoes also make amazing breakfast leftovers—slice them up and toss into a skillet with scrambled eggs or a quick hash.
