These Keto Roasted Green Beans are the side dish I make when a plate needs something bright with a little crunch. Roasting does more work than boiling ever could, and it takes about the same amount of hands-on time.

I reach for this recipe any time I’m serving a main course that could use a lighter, brighter side next to it. It comes together on one pan, and it works just as well on a weeknight as it does next to a holiday roast.
The lemon at the end is what keeps it from tasting like a plain vegetable side. Don’t skip it.
Chef Jenn’s Take on Roasted Green Beans with Almonds and Lemon
The usual mistake with roasted green beans is treating them like a steamed vegetable that just happens to go in the oven. Wet beans and a crowded pan turn what should be blistered and browned into something soft and gray instead.
I’ve tested this with both fresh and frozen green beans, and frozen ones just don’t roast. They hold too much water and steam instead, no matter how hot the oven runs. I’ve also made this with sliced and slivered almonds, and both work fine, so use whichever is already in your pantry.
The real fix is drying the beans completely before they go anywhere near the olive oil, and giving them enough room on the pan that they aren’t touching. Crowd the pan and you’ll get the same soft, steamed result no matter how long they roast.
What You’ll Love About Roasted Green Beans with Almonds and Lemon
- Roasting does more for green beans in twenty minutes than boiling does in twice that time, and the blistered edges are worth the extra step.
- One sheet pan and a small skillet for the almonds is the entire cleanup, which matters on a night when the oven is already full of something else.
- It stays good sitting out for a while, so I don’t have to time it down to the minute the way I do with more delicate sides.
Ingredients
- Green beans – Fresh only. Frozen beans release too much water and steam instead of roasting.
- Olive oil
- Almonds – Sliced or slivered, whichever you already have.
- Lemon juice – Fresh-squeezed, not bottled.
- Lemon zest – Zest the lemon before you juice it.
- Salt and pepper

Preheat the oven to 425°F. This is hot enough to blister the beans before they turn soft all the way through.
Toss the green beans with olive oil, salt, and pepper directly on a baking sheet, then spread them into a single layer. Give them real space here. Beans piled on top of each other steam instead of roasting, no matter how hot the oven is.
Roast for 12 to 15 minutes, flipping halfway through. You’re looking for tender beans with blistered, lightly browned edges, not beans that are still bright green and squeaky.
While the beans roast, toast the almonds in a dry skillet over medium heat, stirring often. They go from golden to burnt fast, so stay at the stove instead of walking away.
Once the beans come out of the oven, drizzle them with the lemon juice and sprinkle the zest over the top while they’re still hot. The heat helps the lemon soak in instead of just sitting on the surface.
Toss everything together and top with the toasted almonds. Serve warm. The texture is best right away, before the almonds have time to soften.
Make It a Meal
I put these on the table next to almost anything that needs a lighter side, especially something rich enough to need the lemon’s acidity. Serve them alongside my Salmon with Lemon Dill Cream Sauce for a meal that leans on lemon twice, or next to Garlic Steak & Mushrooms when you want something heartier.
For a Sunday dinner, I pair this with my Bacon-Wrapped Pork Tenderloin. The bright, crunchy beans balance out the richness of the pork.
Storage
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat on a baking sheet at 375°F for about 5 minutes, or in a skillet over medium heat until warmed through. Freezing isn’t a good option here. The beans lose their texture and turn mushy once thawed.
FREQUENTLY ASKED QUESTIONS
Yes, pecans or walnuts work well in place of almonds. Toast them the same way, watching closely since nuts burn quickly once they start to brown.
No, this recipe skips blanching entirely. Roasting raw beans straight from dry is what gives you the blistered, slightly charred edges, and blanching first would add moisture that works against that.
You can, but stick to vegetables with a similar roast time, like asparagus or thin-cut zucchini. Anything that releases a lot of water, like mushrooms, is better roasted on its own pan so the green beans stay dry.

Notes
Chef Jenn’s Tips
- Dry the beans completely and give them real space on the pan. Wet or crowded beans steam instead of roast, and there’s no fixing that once they’re in the oven.
- Watch the almonds closely once they hit the skillet. They go from golden to burnt in seconds.
- A pinch of red pepper flakes tossed in with the beans adds heat without changing anything else about the recipe.
