The recipe

Roasting green beans brings out the flavors in the vegetable and even makes them a little bit sweet. A bit of garlic, salt and black pepper enhances the green bean goodness. A pinch of red pepper flakes adds just a little bit of a pop to the flavor.


Finally, sliced almonds add some nutty crunch and some visual interest. 


The inspiration

I’m not sure where this recipe originated, but I’ve been making it as a Thanksgiving side dish for about 20 years.


Oven space is hard to find in my kitchen on Thanksgiving day. Since these green beans don’t need to roast very long, I prepare them for roasting and put them in the oven after I take out the turkey.


Then, while the turkey rests for a few minutes and I get the low-carb cranberry sauce, pecan stuffing, and low-carb biscuits on the table, the beans are roasting and ready to go when dinner is ready.

Are green beans keto friendly?

While green beans are not as low in carbohydrates as some above ground veggies, they can still work on a ketogenic diet. 


This recipe has 4 grams net carbs for a 3 ounce serving of green beans. This can easily fit into even a very low carb diet. 


Green beans also deliver nutrients such as calcium, vitamin C, vitamin A and trace minerals. Not a bad way to invest your carb quota, for sure!


How to roast green beans

Roasting green beans is one of the easiest ways to make this vegetable. 


Roasting vegetables must be done in a fairly hot oven–usually 400º to 425º Fahrenheit. Turn the oven on before getting started to allow it time to preheat.


Before roasting, the beans must be completely dry and coated with oil. In this recipe, I add garlic and red pepper flakes to the oil to add extra flavor.


Next, spread the green beans on a baking sheet. They must only be in one layer. They thinner they are spread, the better.


Finally, roast the green beans for about 20 minutes total. You will need to stir them once or twice during this time to allow them to roast evenly.



Can you roast frozen green beans?

I have tried this recipe with both fresh and frozen green beans. While the results are far superior when made with fresh green beans, the recipe will still turn out if you use frozen beans.


If you decide to use frozen beans, be sure to defrost the beans first by putting them in a colander and running cold water over them. 


Once the beans are defrosted, dry them thoroughly before proceeding with the recipe. You may also find that you need to roast them longer.


How to store leftover green beans

While these green beans are best eaten the day they are made, leftovers can be saved for later.


If you have any green beans leftover, store them in an airtight container in the refrigerator. They should last around three days. 


These roasted green beans could also be frozen if you will not be able to use them within three days.

How to reheat leftover green beans

To reheat the green beans, I put them in an oven safe container and heat them in a low temperature oven (250-300º fahrenheit) or until warm. 


Other options to reheat on the stovetop. Simply heat a skillet over medium heat, add about a teaspoon of oil to the skillet, then the leftover beans. Stir beans frequently until warm. Serve immediately. 


Of course, you can microwave them if you prefer. If you take this route, heat them for 30 seconds at a time and stir in between and check to see if they are warm enough. 


Final words

Roasting veggies of all kinds is a simple, but tasty preparation. These green beans make a wonderful side dish perfect for a busy weeknight, or a holiday, or an elegant dinner.
