Ingredients for canned green beans and potatoes
Simple pantry staples transformed into a restaurant-worthy side with crispy potatoes and tangy green beans.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Green Beans 🌿 | 14 ½ oz | Drained, no salt added preferred |
| Baby Potatoes 🥔 | 1 ½ lb | Halved, skin-on for texture |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity variety |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, stems removed |
| Dried Rosemary 🌿 | 1 tsp | Crushed between fingers |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarsely cracked |
| Lemon Zest 🍋 | 1 tsp | From 1 organic lemon |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Chicken Broth 💧 | ¼ cup | Low-sodium preferred |
| Crispy Bacon Bits 🥓 | ¼ cup | Optional, for richness |
The baby potatoes are the star here—halved with skins intact for maximum caramelization. Look for Yukon Golds or red potatoes at Whole Foods or your local market for the best texture. If you can't find baby potatoes, cut larger ones into 1-inch chunks. The canned green beans should be no-salt-added—Green Giant or Del Monte work perfectly. Fresh thyme is ideal, but dried works at one-third the amount if you're in a pinch. For the olive oil, California Olive Ranch or Bertolli are reliable choices that won't overpower the dish.
No fresh herbs? Dried rosemary and thyme will still deliver that aromatic depth—just crush the dried herbs between your fingers before adding to release their oils. Short on lemon zest? Fresh lemon juice plus a pinch of turmeric mimics the color and brightens the dish. The bacon bits are optional but worth the effort—they add a smoky richness that pairs perfectly with the garlicky tang. For a vegetarian version, swap the bacon for toasted breadcrumbs or crispy chickpeas. The chicken broth can be substituted with white wine or vegetable broth, but don't skip it—the liquid helps create that signature crispy edge on the potatoes.
This dish reheats beautifully—just 5 minutes at 375°F restores that crispy texture. Store leftovers in an airtight container for up to 4 days, though I recommend eating it fresh. For meal prep, roast an extra batch and portion into glass containers with tight lids—the potatoes stay crispy for 3 days if you reheat them properly. The lemon zest and fresh herbs can be added fresh right before serving to keep the dish vibrant. This recipe scales perfectly for larger groups—just double the ingredients and use a larger roasting pan.

Step-by-step instructions for one-pan roasted green beans and potatoes
This method delivers perfectly crispy potatoes with tender green beans in a single pan.
Prep and Season the Potatoes
Preheat your oven to 425°F while you prepare the potatoes. Rinse the 1.5 lb baby potatoes thoroughly under cold water, then halve them lengthwise, leaving the skins intact for texture. The smaller size ensures even cooking without overcrowding.
In a large bowl, combine the halved potatoes with 0.25 cup extra-virgin olive oil, 1.5 tsp diamond crystal kosher salt, 0.5 tsp freshly ground black pepper, 1 tsp dried rosemary (crushed between your fingers), and 1 tsp lemon zest. Toss vigorously until every surface is evenly coated. The lemon zest adds a bright contrast that cuts through the richness of the potatoes.
Roast Potatoes Until Crispy
Spread the seasoned potatoes in a single layer on a large, rimmed baking sheet, ensuring they don't overlap. Roast for 25 minutes, stirring once halfway through, until the edges begin to turn golden brown and the potatoes feel tender when pierced with a fork. This initial roast develops the foundational crispiness without fully cooking through.
Here's the thing—if your oven runs hot, you might need to reduce the temperature to 400°F after the first 15 minutes to prevent burning. The goal is crispy edges with a soft interior, not charred potatoes. If they brown too quickly, tent the pan with aluminum foil for the remaining time.
Add Green Beans and Aromatics
After removing the potatoes, increase the oven temperature to 450°F. Drain and rinse the 14.5 oz canned green beans thoroughly to remove any excess sodium. Toss them with the roasted potatoes, along with the 4 minced garlic cloves, 0.25 cup chopped fresh thyme leaves, and 1 tbsp lemon juice. The high heat will caramelize the garlic and thyme, adding depth of flavor.
Return the pan to the oven and roast for an additional 12-15 minutes, stirring once halfway, until the green beans are tender-crisp and the edges of the potatoes are deeply browned. The high heat at this stage ensures the green beans develop a pleasant char while the potatoes finish cooking through. Watch closely—they'll continue cooking slightly after removal.
Finish with Broth and Bacon
Remove the pan from the oven and immediately pour the 0.25 cup chicken broth over the vegetables. Toss gently to distribute the liquid, which will steam the green beans and potatoes, infusing them with additional flavor. Sprinkle the 0.25 cup crispy bacon bits over the top for a smoky richness that complements the bright lemon and herby notes.
Return the pan to the oven for 3-5 minutes to allow the broth to reduce slightly and the bacon to warm through. The vegetables should be piping hot and the bacon should be slightly melted but still crisp. This final step ensures everything is cohesive in temperature and flavor, with the bacon bits adding a satisfying textural contrast.
Rest and Serve Immediately
Transfer the roasted vegetables to a serving platter and let them rest for 2-3 minutes before serving. This brief rest allows the juices to redistribute, preventing them from pooling at the bottom of the pan. The potatoes should be fork-tender with crisp edges, while the green beans maintain a satisfying snap.
Garnish with an additional sprinkle of fresh thyme leaves and a final twist of lemon zest for a pop of color and brightness. Serve immediately while the vegetables are at their peak temperature and texture. This dish pairs beautifully with a simple green salad or crusty bread to soak up the herby, lemony flavors.
Pro Tips For Making Canned Green Beans And Potatoes
- CRANK THE HEAT FIRST: Baby potatoes need a screaming-hot pan to develop that crispy edge—don’t warm it up like you’re making soup. I used to start low and ended up with mushy spuds every time. Get that oil shimmering (medium-high heat) before adding the potatoes, then turn it down to medium after they’re browned.
- DRAIN BEANS DRY: Rinsing canned green beans strips their natural oils, which makes them taste dull. Instead, drain them well, then pat them dry with a paper towel—this helps them crisp up faster and soak up more flavor from the olive oil and garlic. (Yes, it’s a pain, but it’s worth it.)
- SMASH HALF THE POTATOES: Cutting baby potatoes in half ensures even cooking, but here’s the trick: leave some whole. The uncut ones add texture contrast, while the smashed ones release starch faster. Toss them in the pan first—they’ll soften faster and caramelize better.
- TOSS IN THYME LATE: Fresh thyme burns faster than you’d think, especially when garlic hits the pan. Wait until the potatoes are nearly done and the garlic’s golden before adding the leaves—just stir them in for 30 seconds. This keeps their bright aroma intact instead of turning them bitter.
Troubleshooting perfect results
Potatoes Too Soft
If your potatoes turn out mushy instead of crispy, you likely overcrowded the pan or didn't roast them long enough. Baby potatoes should be spread in a single layer with at least ½ inch between each piece.
I've found that roasting at 425°F for 25 minutes (before adding beans) is crucial—any less time means undercooked centers. For extra insurance, parboil the potatoes for 5 minutes in salted water before roasting to jumpstart the cooking process. 🥔
Green Beans Still Crunchy
Canned green beans need careful timing to avoid ending up rock-hard. The key is roasting them at 450°F for 12-15 minutes after the potatoes have started cooking.
If yours remain too firm, try adding 1 tbsp chicken broth to the pan during the final 5 minutes of roasting—this steams them gently while keeping the potatoes crispy.
For extra tenderness, I sometimes add ½ tsp sugar to the oil when tossing the beans, which helps caramelize their natural sweetness. 🌿
Flavor Too Mild
When the dish lacks depth, it's usually because the aromatics didn't infuse properly. Always crush your dried herbs between your fingers before adding to release their essential oils.
For extra punch, add 1 tsp smoked paprika to the potato seasoning or a pinch of red pepper flakes to the final toss. I also recommend using fresh garlic instead of jarred—it makes a noticeable difference.
If you're short on time, a splash of white wine (about 2 tbsp) in place of broth adds complexity without extra effort. 🧄
Bacon Too Dry
The crispy bacon bits can lose their appeal if added too early. Always sprinkle them over the vegetables in the final 3-5 minutes of roasting so they stay crisp.
If your bacon turns soggy, try baking it separately at 400°F for 8-10 minutes until fully crisp, then tossing it with the vegetables just before serving. For a smokier flavor without extra work, swap bacon for ½ tsp liquid smoke in the chicken broth. 🥓
Oven Temperature Issues
Home ovens vary wildly in accuracy—mine runs 25°F hotter than the set temperature! To troubleshoot, use an oven thermometer placed near your roasting pan. If your potatoes brown too quickly, reduce the temperature by 25°F and tent with foil.
For even cooking, rotate the pan halfway through roasting. I've also had success using a dark-colored baking sheet** (like my Lodge cast iron pan) which absorbs more heat for better browning. 🌡️

Frequently asked questions
Can I use fresh green beans instead of canned?
Fresh green beans work beautifully—just trim the ends and cut them into 2-inch pieces before roasting. Since they're denser than canned, reduce the roasting time by 3-5 minutes at 450°F to avoid overcooking. Fresh beans also hold up better to longer roasting, so you can add them with the potatoes from the start if preferred.
What's the best way to store leftovers?
Store in an airtight container for up to 4 days in the fridge. To reheat, spread on a baking sheet at 375°F for 5-7 minutes—this restores crispiness. For meal prep, roast an extra batch and portion into containers, adding fresh herbs and lemon zest just before serving to keep flavors vibrant.
Can I make this dish in a slow cooker?
This recipe works best with high-heat roasting for crispy texture, but you can adapt it! Parboil potatoes for 5 minutes, then combine with drained beans, broth, and seasonings in a slow cooker on Low for 3-4 hours. Finish with a quick broil under the oven's broiler for 3-5 minutes to create crispy edges.
How do I adjust for dietary restrictions?
For vegetarian: Skip bacon and use toasted breadcrumbs or crispy chickpeas for texture. For gluten-free: Ensure broth and bacon bits are certified GF. For lower sodium: Use no-salt-added canned beans and reduce added salt to 1 tsp. The recipe remains adaptable while keeping its signature crispy-tender texture.
Why do my potatoes turn out soggy?
Overcrowding or under-roasting causes soggy potatoes. Spread them in a single layer with ½-inch gaps and roast at 425°F for 25 minutes before adding beans. For extra insurance, parboil potatoes for 5 minutes first to jumpstart cooking. The high heat is key for crispy edges!
