Tasty garlic roasted green beans are even better with a tangy garlic mustard sauce. This is a simple and delicious side dish that’s sure to become a staple!

Sometimes the hardest part of cooking can be trying to get out of a rut. I tend to plan the same meals again and again.
Too much repetition can be a bit boring. I know my family loves certain things, so I tend to make them often.
We love green beans, but it can be tiring to make them the same way. Garlic dill green beans are on frequent rotation here.
If you’re looking for an easy side dish that’s full of flavor, try these garlic roasted green beans. They’re a nice change from beans made in a pan on the stove top.
The lemony sauce elevates these beans a little, making them perfect for a holiday meal, like Thanksgiving. Or, if you’re wanting to make a more traditional Thanksgiving side, try my gluten free vegan green bean casserole.

Ingredient Notes
- Beans – You will get the best result by roasting fresh green beans, but if they are out of season, you can roast frozen green beans. You will want to thaw them out, and then pat them dry with paper towels to remove any excess liquid. You will want to raise the oven temperature to 425 degrees F, and it may take a little longer to roast them.
- Mustard – I love the flavor that mustard gives this sauce. I use regular yellow mustard. If you can’t have mustard, you can just add a little more lemon juice to this recipe! Or if you want to do apple cider instead of lemon juice, you can do that, too!
Preparation
You will need to trim fresh green beans before cooking them. To trim the stem end off the beans, just line up a few of them on the cutting surface, and trim off the stem end with a knife. You can also just break off the stem end with your fingers.

Step by Step Instructions
- Clean the beans and remove the stem end.
- Place on a pan with the olive oil, garlic, and salt and pepper.
- Bake at 400 degrees F for about 25 minutes.

Reheating
You can reheat these, although I think that they are best fresh! You can reheat roasted green beans in the microwave or in a 350 degree F oven until they are warmed through.
