Ingredients for canned green beans and potatoes
Pantry staples and canned shortcuts transform into restaurant-worthy weeknight magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Baby Potatoes 🥔 | 1 ½ lb | Halved for even cooking |
| Canned Green Beans 🌱 | 2 cups | Drained, trimmed if needed |
| Dried Italian Seasoning 🌿 | 1 ½ tbsp | Or 1 tbsp each dried oregano/thyme |
| Garlic Cloves 🧄 | 4 cloves | Minced or finely chopped |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For crispy edges |
| Chicken Broth 💧 | ½ cup | Low-sodium preferred |
| Lemon Zest 🍋 | 1 tsp | Brightens flavors |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Red Pepper Flakes 🔥 | ¼ tsp | Optional for heat |
| Fresh Parsley 🌿 | 0.1 cup | Chopped for garnish |
The potatoes are the star here—baby potatoes (halved) get crispy edges while staying tender inside. Costco or Trader Joe's usually have them pre-washed, but any small potatoes work. If you can't find baby potatoes, cut larger ones into 1-inch chunks. The canned green beans? Look for low-sodium varieties—they taste better without the extra salt. I always grab the French-cut beans at the store, but any kind works. The Italian seasoning is non-negotiable for that herby depth, but if you only have oregano, double it up—it'll still taste amazing.
No Italian seasoning? Mix 1 tsp dried oregano, 0.5 tsp dried thyme, and 0.5 tsp dried basil for a DIY blend. Short on garlic? Garlic powder at half the amount works in a pinch, but fresh is worth it. The olive oil matters—use something fruity and peppery, not the cheap stuff. For extra brightness, lemon juice instead of zest works too (just add 1 tbsp). The red pepper flakes? Skip them if you hate heat, but they add a nice kick for those who like it spicy. And if you're feeling fancy, swap the parsley for fresh basil—it pairs beautifully with the garlic.
This roast reheats like a dream—5 minutes at 350°F and everything's crispy again. Store leftovers in the fridge for 4 days or freeze for 2 months. I always double the recipe because it disappears fast. The potatoes and beans keep their texture beautifully when reheated, so leftovers taste just as good as day one. For extra crispiness, broil for 2 minutes before serving—just watch it like a hawk so it doesn't burn.

Step-by-step instructions for one-pan garlic-herb roast
Here's how to create a flavorful, hands-off dinner that comes together in under 45 minutes.
Prep and Season the Potatoes
Preheat your oven to 400°F while you prepare the potatoes. Rinse the 1.5 lb baby potatoes under cold water, then halve them lengthwise. You want even-sized pieces so they cook uniformly.
Spread the halved potatoes on a baking sheet and toss them with 0.25 cup extra-virgin olive oil, 1.5 tbsp dried Italian seasoning, 1 tsp salt, and 0.5 tsp black pepper. Make sure every piece is coated—this ensures crispy edges and flavorful insides. I like to use my hands for this step so I can feel that every potato gets the seasoning.
Arrange the potatoes cut-side down on a single large oven-safe skillet or cast-iron pan. This positioning helps them crisp up nicely while roasting. Leave about ½-inch space between each piece so they don't steam instead of roast.
Roast the Potatoes Until Golden
Place the skillet in the preheated oven and roast the potatoes for 20 minutes. After 15 minutes, flip each potato piece so they brown evenly on both sides. You'll know they're ready when they develop a beautiful golden-brown crust and feel tender when pierced with a fork.
Here's the thing—don't walk away during this step. I check at 15 minutes and flip them again at 18 minutes for maximum crispiness. The potatoes should be tender but still hold their shape when you test them. If they're browning too quickly, tent them loosely with aluminum foil.
While the potatoes roast, drain the 2 cups canned green beans and trim any ends if needed. Set them aside—they'll join the potatoes soon.
Add Garlic, Beans, and Broth
Remove the skillet from the oven and push the potatoes to one side, creating space for the green beans. Add the 4 minced garlic cloves and 2 cups drained green beans to the empty space in the pan. Toss everything together gently to distribute the garlic and beans evenly.
Pour the 0.5 cup chicken broth and 1 tsp lemon zest over everything, then sprinkle with 0.25 tsp red pepper flakes if you like a little heat. The broth will help steam the green beans while keeping the potatoes moist. Stir everything just once to combine—you don't want to break up the potatoes.
Return the skillet to the oven and continue roasting for another 15-20 minutes until the green beans are tender and the potatoes are fully cooked through. The beans should be bright green and slightly blistered, while the potatoes should be fork-tender with crispy edges.
Finish with Fresh Herbs
Once everything is tender and the flavors have melded, remove the skillet from the oven. Let the mixture sit for 2-3 minutes to allow the juices to redistribute—this prevents them from running out when you serve.
Sprinkle the 0.1 cup chopped fresh parsley over the top just before serving. The parsley adds a fresh contrast to the roasted flavors and makes the dish look vibrant. I like to serve this immediately while everything is hot, but it reheats beautifully if needed.
This one-pan wonder delivers crispy potatoes, tender green beans, and aromatic garlic-herb flavors—all with minimal cleanup. Perfect for those busy weeknights when you still want something delicious!
Pro Tips For Making Canned Green Beans And Potatoes
- Halve the Potatoes First: Baby potatoes take forever to cook if you skip this. Cut them in half before boiling—it cuts cooking time by nearly half and guarantees even doneness. (I learned this the hard way after staring at a pot of undercooked potatoes for 20 minutes.)
- Drain and Rinse Beans: Canned beans hide a salty brine that’ll turn your dish flat. Drain them, then rinse under cold water for 30 seconds—it removes excess sodium and keeps flavors balanced. (Skipping this makes the Italian seasoning fight for space.)
- Sear Garlic Low and Slow: High heat burns garlic before it fragrantizes. Sauté minced cloves over medium-low for 2–3 minutes until golden, not brown. (Yes, it’s slower, but burnt garlic ruins everything.)
- Finish with a Drizzle: Toss the warm potatoes and beans with olive oil after they’re done, not before. A final tablespoon at the end coats everything evenly and makes the Italian seasoning stick. (I used to add it early—mistake.)
Common mistakes when making great canned green beans and potatoes
Overcrowding the Pan
I’ve seen this happen more times than I can count—packing the skillet so tightly that the potatoes steam instead of roast. This turns crispy edges into soggy messes. Leave at least ½-inch space between each potato piece.
If your pan is small, roast the potatoes in batches on a baking sheet first, then transfer them to the skillet before adding the beans. Trust me, a little patience here makes all the difference in texture. 🔥
Skipping the Broth
Some recipes call for dry-roasting, but this dish needs that splash of chicken broth to steam the green beans while keeping the potatoes tender. Without it, the beans turn mushy, and the potatoes dry out.
If you’re worried about extra moisture, just use ¼ cup broth instead—it’ll still work, but the full amount gives the best results.
Underseasoning the Potatoes
The potatoes carry most of the flavor in this dish, so don’t skimp on the seasoning. Toss them with 1.5 tbsp Italian seasoning, 1 tsp salt, and 0.5 tsp black pepper—this ensures every bite is packed with flavor.
I’ve learned the hard way that half-measuring leads to bland results. If you’re unsure, taste a raw potato after seasoning—it should be noticeably flavorful.
Overcooking the Beans
Green beans cook faster than potatoes, so keep a close eye on them after adding the broth. They’re done when they’re tender but still bright green and slightly blistered—about 15-20 minutes total.
If you leave them in too long, they’ll turn mushy and lose their vibrant color. I set a timer for the last 10 minutes of cooking to avoid this common mistake.
Ignoring the Rest Time
Letting the roast sit for 2-3 minutes after pulling it from the oven lets the juices redistribute, so everything stays moist when you serve. Skipping this step means a dry, less flavorful dish.
I promise, those extra minutes make a world of difference. It’s also the perfect time to grab a glass of wine or set the table—no one wants to rush this part. ✨
Using Low-Quality Oil
The olive oil isn’t just for flavor—it’s what creates those golden, crispy edges. Don’t reach for the cheap stuff. A good extra-virgin olive oil (like California Olive Ranch or Bertolli) makes all the difference.
If you’re on a budget, avocado oil works too, but olive oil gives that authentic herby note that ties everything together.

Frequently asked questions
Can I use fresh green beans instead of canned in this recipe?
Fresh green beans work perfectly—just trim the ends and cut them into 1-inch pieces before roasting. They'll need 5-7 extra minutes in the oven since they're denser than canned. For best results, parboil them for 3 minutes first to soften slightly before adding to the pan.
What's the best way to store leftovers?
Store in an airtight container in the fridge for up to 4 days. To reheat, cover with foil and warm at 350°F for 10-12 minutes or until heated through. For extra crispiness, broil for 2 minutes at the end. The flavors actually improve overnight!
Can I make this dish ahead of time?
Yes! Assemble everything except the parsley up to Step 3, then refrigerate uncovered for 1-2 hours before baking. This helps develop deeper flavors. For make-ahead meals, roast completely, cool, then refrigerate for up to 3 days before reheating. The potatoes stay crispy surprisingly well.
What if I don't have Italian seasoning?
No problem! Mix 1 tsp dried oregano, 0.5 tsp dried thyme, and 0.5 tsp dried basil for a DIY blend. For a smoky flavor, add 0.25 tsp smoked paprika. The key is balancing earthy (oregano/thyme) with fresh (basil) notes. Taste as you go—this dish is very forgiving!
Can I add other vegetables to this recipe?
Try adding 1 cup diced bell peppers or ½ cup corn kernels with the beans—they roast beautifully. For heartier meals, toss in ½ cup diced carrots or ½ cup chopped zucchini with the potatoes. Just adjust cooking time by 5-10 minutes if using denser veggies.
