Ingredients for canned diced potatoes

Five simple ingredients transform canned potatoes into a crispy, aromatic side dish worth celebrating.

The potatoes are the star, but the olive oil makes all the difference. Use a high-quality extra-virgin—the fruity notes complement the garlic beautifully. I grab mine from Trader Joe's or Whole Foods; the California Early Harvest variety has the best flavor. Fresh garlic cloves (not the jarred minced stuff) give the most flavor—roast them first if you're feeling fancy, but mincing works just fine. The herbs? Fresh is ideal, but dried thyme at one-third the amount works in a pinch. Just make sure your rosemary isn't woody—it should snap easily when you bend the stems.

No fresh rosemary? Dried rosemary at half the amount gets you close, but it lacks that bright aroma. Short on thyme? Oregano or basil both work, though the flavor profile shifts slightly. The olive oil can be swapped for avocado oil if you prefer a neutral taste, but it won't have the same fruity depth. For extra crispiness, toss the potatoes with an additional 1 tbsp cornstarch before roasting. And if you're serving this with something rich like steak, don't skip the black pepper—it cuts through the fat beautifully.

These potatoes reheat like a dream—toss them back in the oven at 400°F for 5-7 minutes until crispy again. Store leftovers in an airtight container for up to 3 days, but honestly, they disappear faster than that. For meal prep, portion them into small glass containers so they stay crispy longer. The aroma alone will have everyone heading to the kitchen, so make extra if you're feeding a crowd.

Step-by-step instructions for one-pan garlic-herb roasted potatoes

Here's how to transform simple canned potatoes into a restaurant-worthy side dish with irresistible crispy edges.

Drain the 2 cups canned diced potatoes thoroughly but don't rinse them—the starch on their surface helps create that golden crust. Spread them on a clean kitchen towel and pat dry with another towel. You want them as dry as possible for crispy edges, but don't press too hard or you'll crush the pieces.

While the potatoes dry, prepare the herbs by finely chopping the 1 tablespoon fresh rosemary and 1 tablespoon fresh thyme leaves. Remove any woody stems from the rosemary—just the needle-like leaves will give you that aromatic punch. I like to use my fingers to pluck the leaves off the stems rather than chopping them, as it gives a more delicate texture that distributes evenly throughout the dish.

In a large oven-safe skillet with a lid (I prefer cast iron for even heat distribution), heat the 2 tablespoons extra-virgin olive oil over medium heat until shimmering but not smoking. Add the 4 minced garlic cloves and sauté for 30 seconds until they're fragrant but not browned—this prevents bitterness. Immediately remove the pan from heat and stir in the chopped rosemary and thyme leaves.

Let the herb oil mixture cool for 2 minutes while you return the pan to medium heat. This brief cooling period allows the volatile oils in the garlic to mellow slightly, preventing any harsh flavors from overpowering your dish. The herbs will release their essential oils into the oil, creating a fragrant base that will permeate every potato piece.

Add the prepared potatoes to the skillet and gently toss to coat them evenly in the herb oil. Sprinkle with the 0.5 teaspoon diamond crystal kosher salt and 0.25 teaspoon freshly ground black pepper, pressing lightly to help the seasoning adhere. Increase the heat to medium-high and cook for 5 minutes without stirring, allowing the potatoes to develop a crust on one side.

After 5 minutes, give the potatoes a gentle toss and reduce heat to medium. Cover the skillet with a lid and cook for an additional 10 minutes. The lid creates a steam environment that helps cook the potatoes through while the uncovered periods allow moisture to escape, creating those coveted crispy edges. You'll know they're ready when the potatoes are tender when pierced with a fork and the edges are deep golden brown.

Remove the lid and increase the heat to medium-high for the final 2-3 minutes. This last step is crucial for achieving that perfect crispy texture. Watch the potatoes closely—they'll go from tender to perfectly crispy in just minutes. You're looking for edges that are deep golden brown with some areas developing a slight char, while the centers remain fluffy and tender.

Taste one of the potatoes and adjust seasoning if needed. The crispy edges should have a satisfying crunch while the interior remains soft and fluffy. If you find any pieces that aren't crispy enough, return them to the pan for another 30 seconds to 1 minute until they reach your desired texture. Serve immediately while the edges are at their crispest, and enjoy the symphony of garlic, herbs, and that satisfying crunch with every bite.

Essential equipment for great canned diced potatoes

Cast Iron Skillet

I can't emphasize enough how much a 10-inch Lodge cast iron skillet changes the game for this recipe. Cast iron retains and distributes heat perfectly, ensuring even browning and crispy edges without hot spots.

The heavy material also helps maintain consistent temperature during the cooking process, which is crucial when you're working with delicate canned potatoes that can easily turn mushy. 🔥

If you don't own cast iron, a stainless steel skillet with a heavy bottom (like All-Clad) works well too. Just be prepared for slightly less even browning. For non-stick alternatives, I recommend a high-quality ceramic-coated pan—just avoid cheap non-stick coatings that can release harmful fumes at high heat.

The key is choosing a pan with a lid that fits snugly to trap steam during the cooking process.

Oven-Safe Skillet

Since we're finishing this dish on the stovetop but want that oven-baked texture, an oven-safe skillet is essential. Most cast iron and stainless steel pans can handle oven temperatures up to 500°F, which is perfect for this recipe.

If your pan isn't oven-safe, transfer the potatoes to a baking sheet for the final crisping phase at 425°F for 5-7 minutes.

For those with limited counter space, consider a multi-functional pan like the Le Creuset Stoneware Skillet—it's oven-safe, dishwasher-safe, and adds a beautiful presentation to your table. The stoneware material also helps create that perfect crispy crust while keeping the interior tender.

Just be mindful that stoneware takes longer to heat up than metal pans.

Tongs for Tossing

A good pair of long-handled tongs makes all the difference when tossing the potatoes without crushing them. I use OXO Good Grips because the silicone tips protect both the potatoes and your fingers from the hot pan.

The long handles keep your hands safe from the heat while you work. Avoid metal tongs with sharp edges—they can tear the potatoes and make them less appealing.

For the final crisping stage, I recommend using heat-resistant silicone spatulas to gently nudge any stubborn pieces toward the heat source. The flexibility of silicone helps lift the potatoes without damaging their crispy edges.

If you don't have silicone tools, a wooden spoon works in a pinch, but it won't be as effective at high heat.

Measuring Tools

Precision matters when working with canned potatoes—they absorb flavors quickly, and too much or too little seasoning can make or break the dish. A stainless steel measuring cup and spoon ensure accurate measurements, especially for the olive oil and herbs.

I like the OXO Good Grips set because the non-slip handles make measuring effortless while cooking.

For the fresh herbs, a microplane grater works wonders for creating fine, even textures without chopping. If you're using dried herbs, a small spoon with a fine edge helps distribute them evenly.

And for the garlic, a garlic press saves time while ensuring consistent mincing—just don't over-press or you'll get bitter garlic juice.

Thermometer for Perfection

While this recipe doesn't require precise temperatures, a kitchen thermometer helps you monitor the pan's heat. I use an infrared thermometer to check the pan's surface temperature—keeping it between 375-400°F ensures even cooking without burning.

For the potatoes, a simple instant-read thermometer lets you check their internal temperature—aim for 205°F for tender, fluffy centers.

If you're new to thermometers, start with an instant-read model like the Thermoworks Thermapen ONE—it's affordable, accurate, and easy to use. For those who want to go pro, a dual-probe thermometer (like the Meater) lets you monitor both the pan and potatoes simultaneously.

The key is avoiding overcooking—the potatoes should be tender but still hold their shape when pierced.
