We adore these Vegan Green Beans with Pine Nuts and Lemon Pepper Green Beans, as well as more time-intensive Green Bean Bundles with Bacon.

This easy side dish came about when I drizzled homemade salad dressing onto green beans to finish up the dressing a few years back. Turns out, it gave the green beans an added savory quality.

Oven Roasted Green Beans are simple and easy to make. They also require little-to-no hands-on time before you pop them in the oven and bake until crisp tender. They are also a family favorite, which is saying something because everyone in this family has Opinions about our food.

To be honest, these simple steps pack such a wonderful punch. And then you go and finish the beans with a sprinkle of flaky sea salt and they are just SO tasty.

• Kitchen shears or a sharp knife
• Cutting board
• Colander
• Large baking sheet with a rim or a roasting pan
• Large mixing bowl
• Smaller mixing bowl
• Whisk
• Tongs

Here’s what you need to grab at the grocery store:

• Fresh green beans — this fresh produce is key to this recipe. We have not tried it with frozen green beans, and I do not recommend using them.
• Extra virgin olive oil — or another neutral tasting oil, like avocado oil. I prefer olive oil to vegetable oil, but it certainly will work here.
• Balsamic vinegar — this vinegar adds much-needed acidity to the dish. You could replace it with bright lemon juice or another vinegar, though I love balsamic when paired with green beans. 
• Grainy mustard — this is going to help the dressing ingredients emulsify, as well as add unique texture to the final dish.
• Sriracha sauce — or another hot sauce to add a pop of heat.
• Kosher salt — medium grain kosher salt is my go-to for recipes like this. Please note that we have this, as well as finishing salt. They are different! 
• Black pepper — we like to crack our own with a pepper mill, but the pre-ground kind also works.
• Flaky sea salt — we sprinkle this on the green beans once they’re out of the oven, and it adds a wonderful pop of saltiness with each bite! A little goes a long way, so don’t overdo it. 

How to make this Oven Roasted Green Beans recipe:

Preheat the oven to 425°F. Place a rimmed sheet pan on the countertop, and set aside. You can line the pan with parchment paper or aluminum foil, if desired.

Wash and trim green beans. Once trimmed, place in a large bowl or on the rimmed sheet pan.

Whisk together the olive oil, balsamic vinegar, mustard, Sriracha, kosher salt, black pepper in a smaller bowl. Mix until the ingredients have incorporated. You could also do this in a mason jar and shake it up until the dressing has imulsified.

Pour the wet ingredients on top of the green beans.

Toss the green beans with the sauce using tongs until each bean is coated. (You may also do this on the sheet pan, if you don’t want to dirty bowls.)

If you’ve mixed them in a bowl, pour the green beans onto the rimmed sheet pan in a single layer.

Roast green beans for 15-20 minutes in the preheated oven, or until the green beans are fork tender and slightly crispy, then remove from the oven.

Finish with a healthy sprinkle of flaky sea salt, then serve immediately.

How to store:

​Let the green beans cool, and store in an airtight container in the refrigerator for 3-4 days.

Reheat in the microwave until warmed through. You may also reheat in the air fryer or toast them in a toaster oven to get that crunchiness back.

Erin’s Easy Entertaining Tips and Tricks

Listen. Green beans aren’t the fanciest vegetables, but so many people love them that I highly recommend serving them when you host a dinner party… or are hosting holiday festivities.

Here’s what I would do with these green beans if serving them to a crowd:

• Double or triple the recipe. ​If your guests enjoy green beans, make more of ’em. You might need more than one rimmed baking sheet.
• Prep the green beans early. Green beans are hearty, so you can wash, trim and store them in the fridge for hours or even days beforehand. 
• Choose a fun serving platter to serve them on! And have extra flaky sea salt on the table in case your guests want to add a pinch more to theirs.

Quick tips and tricks to the best green beans

• Double or triple the recipe for a crowd.
• Switch up the flavors. Leave out the hot sauce and add a pinch of red pepper flakes instead. Serve with fresh herbs, like fresh basil or thyme. Add minced garlic to the dressing for garlic flavor! Add a sprinkle of grated parmesan cheese after roasting.
• Store leftovers in an airtight container. Reheat in the microwave in 30-second bursts until warmed through. You can also crisp them in an air fryer, if desired.
