How Long to Cook Green Beans in Oven

How long you need to cook green beans in the oven depends on how you like them cooked. If you prefer your green beans soft and tender, 15 minutes is usually enough time. If they’re slightly crunchy with a bit of bite, 20-25 minutes will do the trick; if you want them more on the al dente side (still very crisp), 30 minutes should be good enough.

As far as preparation goes, just wash and trim off any loose ends from your fresh produce before putting them into an ovenproof dish or baking sheet with some olive oil and salt, then placing it in an oven preheated at 350 F for about half an hour until done!

Step 1: Preheat oven to 400 degrees F.

  • Preheat oven to 400 degrees F. If you want to cook them at a different temperature, use your own judgement.
  • If you don’t have an oven, you can use a microwave or stovetop or slow cooker instead!

Step 2: Place green beans on a lightly greased cookie sheet.

Once you’ve prepped your green beans, it’s time to put them in the oven. The next step is to place them on a lightly greased cookie sheet.

If you don’t have any greased cookie sheets, don’t worry! Just use one of your other pans or dishes that isn’t being used for anything else in the kitchen at that moment. You could also just use parchment paper or aluminum foil if you have those lying around too–they work just as well as greased ones will!

The only thing to keep in mind when choosing which pan/dish/piece of parchment paper to use is whether or not it has enough room for all of your green beans (or whatever food item(s) are being cooked). If there isn’t enough space for all of them, then some may burn while others remain uncooked; if there is too much space between each piece before baking begins (and even more so once everything starts cooking), then nothing gets done properly since heat cannot circulate evenly throughout each batch individually without mixing together into one big mess on top instead…

Step 3: Bake for 15 minutes, then check; you may need to cook another 5 minutes or so, depending on how large your beans are.

Now it’s time to bake the green beans. Place them in a baking dish, and bake for 15 minutes. Check on them; if they’re not done, you may need to cook an additional 5 minutes or so.

The cooking time will vary based on the size of your beans–smaller ones will cook faster than larger ones–so just keep an eye on them while they’re in the oven until they reach your desired level of tenderness.*

You can also cook these on top of the stove if you prefer: Bring some water up to a boil in a large pan over medium heat, then add in 2 tablespoons butter or olive oil (or both!), 1/2 teaspoon salt and 1/2 teaspoon pepper (or whatever seasonings sound good). Add some fresh herbs if desired: thyme goes well with green beans; tarragon pairs well with seafoods like shrimp or scallops; rosemary complements pork nicely…you get the idea! Once everything has melted together nicely into one big happy saucepan full o’ goodness, add about 1 pound trimmed fresh green beans (1 inch long) into this mixture and stir until evenly coated before reducing heat down slightly under medium-low heat for about 10 more minutes — stirring occasionally throughout so nothing burns onto bottom surface while flavors blend together nicely throughout entire dish.”

Step 4: Once the green beans are tender but not mushy, remove from the oven and serve.


Now that your green beans are done, it’s time to serve them. The best way to tell if your green beans are tender but not mushy is by tasting one! If it’s still too crunchy, put them back in the oven for another 10 minutes or so. You can also use this method with other vegetables like broccoli and carrots.

If you’re cooking for a large group of people and don’t want to do all this math every time you make dinner (or even just one person who eats more than three servings of vegetables per day), try doubling or tripling this recipe so you have enough green beans leftovers for lunch tomorrow!

The best way to cook green beans is to roast them in the oven for about 15 minutes at 400F

You can also roast them in the oven for about 15 minutes at 400F, but that might take a little longer than you’d like. The best way to cook green beans is to steam them for about 10 minutes and then finish them off with a quick saute in olive oil or butter (with garlic if you’re feeling fancy).

This will bring out their natural sweetness.

Green beans are packed with fiber and vitamin K, which helps keep blood pressure down; vitamin A and C; folate (a B vitamin), magnesium (an essential mineral), potassium (another essential mineral) plus calcium!


Now that you know how long to cook green beans in the oven, you can make this delicious side dish for your next family dinner or holiday meal. It’s easy enough for kids to help with and will taste great with any meat entree!
