Canned Whole New Potatoes Recipe: Herb-Butter Roast With Crispy Edges

Transforming canned whole new potatoes into a crispy, herb-butter roasted side dish is simpler than you might think—this method delivers restaurant-quality results with minimal effort.

The secret lies in high-heat roasting that caramelizes the edges while keeping the insides tender, all while infusing them with aromatic herbs and rich butter. I developed this technique after discovering how canned potatoes could rival fresh when prepared with the right seasoning and cooking approach.

This recipe requires just five key ingredients—canned whole new potatoes, butter, fresh herbs, garlic, and salt—yet delivers complex, savory flavors that elevate any main dish. The process takes about 45 minutes, including preparation, and transforms ordinary canned potatoes into a side that’s crispy on the outside and velvety inside.

Perfect for weeknight dinners or holiday meals, this method works equally well as a standalone side or paired with proteins like roasted chicken or steak.

What sets this herb-butter roast apart is the crispy texture achieved through proper roasting techniques and seasoning balance. The potatoes develop a golden-brown crust that holds up beautifully, while the herb-infused butter creates a flavorful coating in every bite.

This approach ensures even distribution of seasoning without overpowering the natural potato taste, making it universally appealing.

The beauty of this recipe lies in its versatility—it adapts effortlessly to different dietary needs while maintaining its professional-quality results. Whether you’re serving a family meal or preparing for a gathering, these herb-butter roasted potatoes will be the star of your table.

Let’s get started with this foolproof method that transforms canned potatoes into a gourmet side dish.

Ingredients for canned whole new potatoes

Five simple ingredients transform canned potatoes into a restaurant-worthy herb-butter roast with crisp edges.

The quality of your herbs and butter makes all the difference here. Fresh thyme and rosemary from the grocery store’s produce section (not the dried aisle) will give you the most vibrant flavor. For butter, Plugrá or Land O’Lakes unsalted work perfectly—they have just the right fat content for crisping. If you’re using dried herbs, double the amount but know they won’t have the same depth. The potatoes themselves should be 15 oz cans—the smaller 10 oz cans won’t yield enough for this recipe. Look for brands like Goya or Del Monte in the canned vegetable aisle, not the ‘baking’ section.

No fresh herbs? Dried thyme and rosemary at double the amount will work, though the flavor won’t be as bright. Running short on thyme? Fresh oregano or marjoram can substitute in a pinch. For the garlic, jarred minced garlic is acceptable but fresh minced will give better flavor. The butter can be European-style butter if you prefer—just use the same quantity. If you’re concerned about the potatoes being too wet after draining, pat them dry with paper towels before roasting for extra crispiness. The salt measurement is a guideline—taste as you go since different potato brands vary in saltiness.

These roasted potatoes keep their crispy edges for about 3 days when stored in an airtight container at room temperature, though they’re best served fresh. For longer storage, reheat at 350°F for 10-15 minutes until warmed through. The herb butter mixture can be prepped 2 hours ahead and stored in the fridge—just toss the potatoes with it right before roasting. For meal prep, portion the roasted potatoes into glass containers with a sprinkle of fresh herbs on top to maintain color and flavor. They reheat beautifully and make an excellent make-ahead side dish for holiday meals.

Step-by-step instructions for herb-butter roasted canned whole new potatoes

This method delivers restaurant-quality crispy edges while keeping the interiors tender and flavorful.

In a small mixing bowl, combine the 0.5 cup unsalted butter with the 0.25 cup chopped fresh thyme leaves and 0.25 cup finely chopped fresh rosemary. Use a fork to break down the butter into small, even cubes while incorporating the herbs. This ensures the aromatic oils from the rosemary and thyme will infuse throughout the butter during roasting.

Add the 4 minced garlic cloves and mix thoroughly. Season the mixture with 1.5 teaspoons diamond crystal kosher salt and 0.5 teaspoon freshly ground black pepper. The garlic should be evenly distributed to prevent any single potato from becoming overly pungent. This herb-butter blend is the secret to achieving that perfect balance of crispy exterior and rich, herby flavor.

Drain the 4 cans canned whole new potatoes thoroughly, using a colander to remove excess liquid. Shake the colander gently to separate any clumped potatoes. Transfer them to a large mixing bowl and toss gently to distribute the heat evenly.

Add the prepared herb-butter mixture to the potatoes and toss again, this time more vigorously, ensuring each potato is fully coated. The butter should melt slightly from the warmth of the potatoes, creating a sticky paste that clings to every surface. If some potatoes remain dry, add a few extra spoonfuls of the herb-butter mixture to guarantee even coverage. This step is critical for achieving those coveted crispy edges.

Preheat your oven to 425°F and line a large baking sheet with parchment paper or aluminum foil for easy cleanup. Arrange the coated potatoes in a single layer, spacing them about ½ inch apart to allow for even air circulation. This spacing prevents steaming and promotes crispiness.

Roast the potatoes for 30-35 minutes, stirring once halfway through the cooking time. You’ll know they’re ready when the edges are deep golden brown and the potatoes feel firm to the touch. The internal temperature should reach 205°F when measured with an instant-read thermometer. Resist the urge to check too often—opening the oven door causes temperature fluctuations that can lead to uneven cooking.

Once the potatoes reach the perfect golden-brown state, transfer them to a serving platter. Let them rest for 5 minutes before serving. This resting period allows the residual heat to finish cooking the interiors while maintaining the crispy texture you’ve worked so hard to achieve.

Serve immediately while the edges are still crisp. The potatoes should be firm yet tender inside, with a rich, herby flavor from the butter and a satisfying crunch on every bite. If you find the edges losing crispiness as they cool, simply return them to the oven at 400°F for 2-3 minutes to restore that perfect texture.

Best sauces and condiments for these flavors

Classic Garlic-Herb Oil

Infuse your roasted potatoes with a bold, aromatic touch using a simple garlic-herb oil instead of butter.

Heat ½ cup olive oil with 4 minced garlic cloves, ¼ cup chopped fresh parsley, 1 tbsp lemon zest, and 1 tsp red pepper flakes in a small saucepan over low heat for 5 minutes.

Let it cool, then toss the drained potatoes in this mixture before roasting. The olive oil adds a fruity depth while the lemon zest brightens the dish. 💛

Creamy Dill Sour Cream

For a tangy, creamy twist, mix ½ cup sour cream with 2 tbsp chopped fresh dill, 1 tbsp minced chives, 1 tsp lemon juice, and ½ tsp onion powder.

Toss the roasted potatoes in this mixture during the last 5 minutes of roasting to create a velvety coating. This works especially well with roasted potatoes served alongside grilled fish or chicken. The sour cream adds richness without overpowering the potatoes’ natural flavor.

Spicy Chipotle Aioli

Elevate your dish with a smoky, spicy kick by preparing a chipotle aioli. Blend ½ cup mayonnaise with 1 tbsp adobo sauce (from canned chipotles), 1 tsp honey, ½ tsp smoked paprika, and 1 minced garlic clove until smooth.

Drizzle this over the roasted potatoes just before serving. The aioli adds a bold, smoky contrast that pairs beautifully with the crispy edges. For extra heat, add a pinch of cayenne pepper.

Honey-Mustard Glaze

Create a sweet and tangy glaze by combining 3 tbsp Dijon mustard, 2 tbsp honey, 1 tbsp apple cider vinegar, and 1 tsp fresh thyme leaves.

Warm the mixture in a small saucepan over low heat for 3 minutes, then brush it over the potatoes during the last 10 minutes of roasting. This glaze caramelizes beautifully, adding a glossy finish and a perfect balance of sweet and tangy flavors.

It works wonderfully with roasted potatoes served alongside pork or duck.

Parmesan-Pepper Crust

For a cheesy, crispy topping, toss the roasted potatoes with a mix of ¼ cup grated Parmesan cheese, 1 tbsp freshly cracked black pepper, and 1 tsp garlic powder during the last 5 minutes of roasting.

The Parmesan melts slightly, creating a golden, savory crust that adds a salty depth. This variation is perfect for serving alongside steak or hearty pasta dishes. The pepper enhances the crispiness, making every bite more satisfying. 🌟
