Side Dishes
Transforming canned green beans and potatoes into a restaurant-worthy side dish only takes one pan and 30 minutes of your time. The secret lies in roasting them with garlic, herbs, and a splash of broth until they're golden and tender—no fancy ingredients required.
I first developed this recipe during a particularly busy week when I needed a foolproof side that would complement any main dish.
This one-pan method eliminates cleanup while delivering maximum flavor. The potatoes develop a crispy exterior with creamy interiors, while the green beans caramelize just enough to bring out their natural sweetness.
A simple blend of garlic, thyme, and rosemary infuses everything with aromatic depth that turns this humble side into something special.
What you'll end up with is a dish that looks and tastes like it belongs on a holiday table—crispy edges on the potatoes, vibrant green beans, and a sauce at the bottom of the pan that's packed with flavor.
It's the kind of side that disappears faster than you can say "seconds please." The best part? It reheats beautifully for leftovers.
Perfect for weeknight dinners, holiday gatherings, or meal prep—this recipe scales effortlessly from family dinners to crowd-pleasing buffets. Let's get started with this simple yet impressive one-pan wonder that will have everyone asking for your recipe.
Ingredients for canned green beans and potatoes
Just eleven ingredients for a side that tastes like it belongs on a holiday table.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Green Beans 🌽 | 14 oz | Drained, no salt added |
| Baby Potatoes 🥔 | 1 ½ lb | Halved, unpeeled |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or 1 tsp dried thyme |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, stems removed |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For roasting |
| Chicken Broth 💧 | ½ cup | Low-sodium preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Lemon Zest 🍋 | 1 tsp | Optional, for brightness |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, optional |
Baby potatoes are your secret weapon here—they roast faster and get that perfect crispy edge. Grab the small ones from the produce section (or the pre-washed bagged kind if you're in a hurry). The canned green beans? No salt added is key—skip the pre-seasoned ones. For the herbs, fresh thyme and rosemary make all the difference, but dried works in a pinch. I always double-check the chicken broth label for low-sodium—Swanson or Pacific Foods are my go-tos. The Parmesan is optional but adds that restaurant touch when sprinkled on top.
No fresh rosemary? Dried at half the amount works fine. Short on thyme? Oregano or marjoram are decent swaps, though they'll change the flavor slightly. No lemon zest? Fresh lemon juice brightens things up just as well. The olive oil should be fruity and peppery—California Olive Ranch or Bertolli are great budget options. The garlic can be pre-minced from a jar if you're really pressed, but fresh is always better. For a vegetarian version, swap the chicken broth for vegetable broth—no one will notice the difference.
This dish reheats like a dream—5 minutes at 350°F brings it right back to life. Store leftovers in the fridge for 4 days or freeze for 3 months. I like to portion mine into individual containers so I can grab and go. The potatoes and beans keep their texture beautifully when reheated, and the herbs stay fragrant. Double the recipe if you're feeding a crowd—it's that easy.

Step-by-step instructions for one-pan garlic-herb roast
Here's how to turn simple ingredients into a flavorful, hands-off meal that's ready in under 45 minutes.
Prep the Potatoes and Drain the Green Beans
Start by halving the 1.5 lb baby potatoes lengthwise, leaving the skins on for texture. Give them a quick rinse under cold water to remove any dirt, then pat them completely dry with paper towels—this ensures they'll crisp up nicely in the oven. While the potatoes are prepping, drain the 14 oz canned green beans thoroughly, making sure to remove all the liquid. I like to give them a quick rinse too to wash away any canned flavor.
Spread the drained green beans on a clean kitchen towel and pat them dry as well. This step is crucial because any moisture left on the vegetables will steam them instead of letting them develop that beautiful roasted flavor. Once everything is dry, toss the potatoes and green beans together in a large bowl with 1 tbsp fresh thyme leaves, 1 tbsp chopped fresh rosemary, 1 tsp salt, and 0.5 tsp black pepper. Give them a good mix so the herbs and seasonings coat every surface evenly.
Roast the Potatoes and Green Beans
Preheat your oven to 425°F while you're prepping. Once it's hot, place a large, oven-safe skillet or baking dish on the stovetop over medium heat. Add the 0.25 cup extra-virgin olive oil and let it warm for about 1 minute—just until it's shimmering but not smoking. This is the perfect temperature to start building flavor.
Carefully transfer the seasoned potatoes and green beans to the warm skillet. Spread them out in a single layer, making sure they're not overcrowded. Let them cook undisturbed for 5 minutes so they start to develop a golden crust. After that time, use a spatula to gently flip each piece, then return them to the oven. Roast for 20-25 minutes, stirring halfway through, until the potatoes are tender when pierced with a fork and the green beans are blistered in spots.
Add Garlic and Broth for Extra Flavor
While the vegetables are roasting, mince the 4 cloves garlic cloves and sprinkle them over the top of the potatoes and green beans. Give everything a quick stir to distribute the garlic evenly. Then, pour the 0.5 cup chicken broth over the mixture, letting it seep down into the pan. The broth will help create a light, flavorful sauce that clings to the vegetables.
Return the skillet to the oven and continue roasting for another 5-7 minutes, until the garlic is fragrant and the vegetables are tender all the way through. You'll know they're done when the potatoes are fork-tender and the green beans are bright green with slightly crisp edges. The broth will have mostly evaporated, leaving behind a savory, herby coating.
Finish with Lemon and Parmesan
Remove the skillet from the oven and let it cool for 2-3 minutes. This gives the vegetables a chance to absorb any remaining juices. Sprinkle the 1 tsp lemon zest over the top for a bright, fresh finish, and stir gently to combine. If you're using the 0.25 cup freshly grated parmesan cheese, add it now and toss everything together one last time. The parmesan will melt slightly from the residual heat, creating a creamy, cheesy finish.
Taste and adjust the seasoning if needed—you might want to add a pinch more salt or a crack of black pepper to taste. Serve the roasted potatoes and green beans immediately while they're hot, straight from the skillet. The flavors will be at their peak, and the texture will be perfect—crispy edges on the potatoes, tender centers, and bright, herby green beans. This dish pairs beautifully with crusty bread or a simple green salad.
Pro Tips For Making Canned Green Beans And Potatoes
- Parboil Potatoes First: Baby potatoes take forever to soften when tossed raw—save time by parboiling them for 8-10 minutes in salted water until they yield to a fork. Drain and cool before adding to the pan, or they’ll turn to mush when you’re not looking.
- Drain & Rinse Beans: Canned beans are packed with brine or syrup—drain them and give them a quick cold-water rinse to cut the saltiness and clean up the texture. Skip this, and your dish will taste like a sad, salty soup.
- Brown Garlic Low: Garlic burns faster than you think, especially when you’re distracted by potatoes. Cook it on medium-low heat for 2-3 minutes until golden, not blackened—otherwise, you’ll end up with bitter, burnt bits instead of nutty flavor.
- Add Herbs Last: Fresh thyme and rosemary lose their bright aroma when simmered too long. Tuck them in with the beans and potatoes only in the final 2 minutes of cooking, or they’ll turn dull and release their oils into a greasy mess.
Common mistakes when making this recipe
Skipping the Drying Step
This is my biggest rookie mistake—leaving moisture on the potatoes or green beans. When I first tried this recipe, I rushed through drying them with paper towels, and the result was sad, soggy vegetables instead of crispy, caramelized perfection.
Always pat them completely dry before seasoning. Use two layers of paper towels if needed, and press firmly to remove every drop of water. 💧
Overcrowding the Pan
The key to great roasted potatoes and green beans is surface area. I once tried to fit all the potatoes into a single layer in a crowded skillet, and they steamed instead of roasting.
Spread them out in one layer with space between each piece—this ensures they crisp up properly. If your pan is too small, roast them in batches or use a larger baking sheet.
Underseasoning the Broth
Many store-bought chicken broths are packed with sodium, which can make your dish taste bland or overly salty. I've learned to always check the label and choose low-sodium options like Swanson or Pacific Foods.
If you're using a high-sodium broth, reduce it by half with water. Taste the broth before adding it to the pan—season it with a pinch of salt if needed.
Not Testing for Doneness
I can't tell you how many times I've pulled roasted potatoes out of the oven thinking they were done, only to find them still hard in the center. Always pierce a potato with a fork or knife to check for tenderness.
The green beans should be bright green with slightly blistered edges. If they're still crunchy, return them to the oven for another 5 minutes.
Ignoring the Resting Time
After roasting, I used to transfer everything straight to serving dishes without letting it rest. This causes the juices to spill out, leaving you with dry vegetables. Let the roasted potatoes and green beans rest in the pan for 2-3 minutes before serving.
This allows the flavors to meld and the juices to redistribute, resulting in a more cohesive dish.
Using Pre-Cooked Potatoes
Baby potatoes are already partially cooked, but they still need to roast to develop flavor and texture. If you're tempted to use pre-boiled or microwaved potatoes, resist the urge! They won't crisp up properly and will turn out mushy.
Always roast them from their raw state for the best results. This is one of those times where patience pays off. ⏰

Frequently asked questions
Can I use fresh green beans instead of canned?
Fresh green beans work beautifully—just trim the ends and cut longer beans into 2-inch pieces. Roast them for 5-7 minutes less than canned beans since they're more moisture-rich. For best results, blanch fresh beans in boiling water for 2 minutes first to remove excess moisture, then pat completely dry before roasting.
What if I don't have baby potatoes?
Regular potatoes work fine—just cut them into 1-inch cubes instead of halves. Larger potatoes may need 5-10 extra minutes of roasting time. For even cooking, avoid thick chunks. Red potatoes or Yukon golds hold up best, while russets can dry out faster.
How can I make this vegetarian?
Swap the chicken broth for vegetable broth and add 1 tsp smoked paprika or ½ tsp onion powder for depth. For extra protein, toss in ½ cup chickpeas with the potatoes. The dish will still be hearty and flavorful without meat.
Can I make this ahead of time?
Yes! This dish reheats wonderfully. Cook as directed, then store in an airtight container for 3-4 days in the fridge. Reheat at 350°F for 10-15 minutes until warmed through. For freezing, portion into individual containers and freeze for up to 3 months—thaw overnight in the fridge.
What's the best way to serve this?
This one-pan wonder pairs perfectly with grilled chicken, roasted meats, or even as a vegetarian main. For extra flair, serve with a dollop of sour cream, fresh dill, or crusty sourdough bread. The herby sauce at the bottom makes it great for dipping—don't skip the leftovers!
