Save this recipe on:

I have a weakness for simple side dishes that deliver maximum flavor with minimal effort, and these Butter Swim Parmesan Roasted Potatoes are exactly that. The moment I pulled them out of the oven for the first time, I knew I had stumbled upon a new favorite. Each baby red potato gets crispy on the outside, soft on the inside, and drenched in a buttery, garlicky, cheesy layer that turns the humble spud into a showstopper. It’s the kind of recipe that makes everyone ask for seconds—and the recipe.

What I love most is how hands-off it is. The oven does all the magic while you focus on other parts of dinner (or pour yourself a glass of wine). It’s also incredibly versatile. I’ve served these potatoes with everything from grilled steak to roasted chicken, and even brought them to potlucks where they disappear in minutes. Whether you need a quick weeknight side or something for the holidays, these potatoes check all the boxes.

What Kind of Potatoes Should I Use?

Baby red potatoes are the star here. Their thin skin crisps beautifully and their waxy interior holds shape without falling apart. I recommend keeping them whole if they’re small or halving them if a few are a bit larger. If you only have Yukon Gold or baby Dutch potatoes on hand, those will work too—just aim for similar size so they cook evenly.

Options for Substitutions

• Butter: If you’re dairy-free, a vegan butter alternative will still give you good results.
• Parmesan: Swap with Pecorino Romano or even nutritional yeast for a dairy-free option.
• Seasoning: Garlic salt can be used in place of minced garlic for speed, and Italian seasoning can substitute for any herbs you don’t have.
• Potatoes: Yukon Gold or fingerlings work great if you don’t have baby reds.
• Oil: You can reduce butter and add a splash of olive oil to lighten it up a bit.

Ingredients for This Butter Swim Parmesan Roasted Potatoes Recipe

• Baby Red Potatoes: These small potatoes have thin skins and a creamy interior, perfect for roasting. Their size allows for even cooking and crispy edges.
• Butter: The key element of the “swim”—it creates a rich, golden bath that crisps the potatoes from underneath.
• Parmesan Cheese: Adds a salty, umami crunch to the base layer, enhancing both texture and flavor.
• Garlic (minced or granulated): Infuses the butter with robust flavor that seeps into the potatoes as they roast.
• Italian Seasoning: A blend of herbs like oregano, basil, and thyme adds a savory, aromatic touch.
• Salt & Black Pepper: Essential for seasoning the potatoes and bringing out all the other flavors.
• Crushed Red Pepper Flakes (optional): For a subtle heat that balances the richness of the butter and cheese.

Step 1: Preheat and Prep Your Pan

Preheat your oven to 400°F (200°C). While it heats, grab a rimmed baking sheet and add a full stick of butter (1/2 cup). Place the sheet in the oven for a few minutes until the butter is completely melted.

---

Step 2: Season the Butter Base

Once the butter is melted and sizzling, remove the pan and immediately sprinkle the entire base with Parmesan cheese, garlic, Italian seasoning, salt, pepper, and red pepper flakes if using. This cheesy-herb layer will bake into a crisp crust.

---

Step 3: Prepare the Potatoes

Rinse and pat dry your baby red potatoes. Keep them whole if they are bite-sized, or cut in half if they are slightly larger to ensure even cooking.

---

Step 4: Arrange Potatoes on the Pan

Place the potatoes cut-side down (or whole) directly into the seasoned butter-Parmesan mixture. Press them gently so they make good contact with the pan.

---

Step 5: Roast to Perfection

Bake in the preheated oven for 35 to 45 minutes, depending on the size of the potatoes. You’ll know they’re ready when the tops are tender and the bottoms are golden brown and crisp.

---

Step 6: Serve and Enjoy

Remove the potatoes from the oven and let them rest a few minutes. Use a spatula to gently lift them off the pan—the crispy, cheesy bottoms will come off as a delicious layer. Serve hot, garnished with fresh herbs or extra Parmesan if desired.

How Long to Prepare Butter Swim Parmesan Roasted Potatoes

Making these crispy, buttery potatoes doesn’t take long at all, but timing does matter to get that signature golden crust.

Prep Time: The prep work—melting butter, seasoning the pan, and arranging the potatoes—takes about 10 to 15 minutes. It’s even faster if you’ve already washed and sorted the potatoes in advance.

Cook Time: Once in the oven, expect them to roast for 35 to 45 minutes at 400°F. Smaller potatoes will need around 35 minutes, while slightly larger ones may go up to 45. Don’t rush the process; that time is key to forming the crispy Parmesan base.

Tips for Perfect Butter Swim Parmesan Roasted Potatoes

• Make sure the butter is hot before adding seasonings and potatoes—it jumpstarts the crisping.
• Arrange potatoes in a single layer with space between them to ensure even cooking.
• Use freshly grated Parmesan for the best melt and flavor. Pre-grated varieties may not crisp as well.
• For extra crisp, broil for the last 2 minutes while watching closely.
• Let the potatoes rest 5 minutes before removing them from the pan to allow the cheesy layer to firm up.

---

Watch Out for These Mistakes While Cooking

• Using cold butter: If you don’t preheat the pan, the crust won’t develop.
• Overcrowding: Too many potatoes will steam instead of roast, leading to soggy bottoms.
• Skipping the seasoning base: This layer is what forms the crispy, cheesy crust.
• Using wet potatoes: Moisture prevents browning. Always dry your potatoes well.
• Lifting too early: Removing potatoes before they rest may tear the crust. Be patient.

Storage Instructions

In the Fridge: Let the potatoes cool completely, then store them in an airtight container in the fridge for up to 4 days. To reheat, place them cut-side down in a skillet or toaster oven to re-crisp the bottom.

In the Freezer: These are best fresh, but if you do freeze them, store in a single layer in freezer-safe containers. Reheat directly from frozen in a hot oven until warmed through and crispy.

Frequently Asked Questions

How do I make the potatoes extra crispy?

Make sure your butter is sizzling hot before adding the potatoes and don’t overcrowd the pan. A quick broil at the end helps too.

Can I use a glass or ceramic baking dish?

You can, but a metal baking sheet conducts heat better and will give you a crispier bottom.

Can I prep this ahead of time?

Yes, you can wash and cut the potatoes and pre-mix the seasonings. Melt the butter and assemble right before baking.

What kind of Parmesan works best?

Freshly grated Parmesan gives the best melt and crispy texture. Avoid the powdered kind.

Can I use sweet potatoes?

You can, but they won’t get quite as crispy and may need a bit longer in the oven due to higher moisture content.
