Are green beans one of your favorite vegetables? If so, we’re guessing you might be familiar with low carb green bean casserole like this one. It’s delicious with green beans that have a little snap still left in them, a homemade creamy mushroom gravy sauce and topped off with some crispy fried onions. While delicious, we do tend to make it more during the holiday season. It’s a great option if you’re craving it.

We’d also like to make sure we mentioned this green bean salad with feta and lemon. Blanched green beans with salty feta and fresh lemon. It’s just as easy as these roasted green beans with garlic and lemon! So there’s a few different ways we make green beans on repeat, and we wanted to make sure you knew about those too.

Lastly, we’d like to mention this baked asparagus with lemon, dill and goat cheese if you’re in an asparagus mood! Incredibly simple and tasty to suit whatever you’re craving, or whatever is in the fridge. We love the combo of lemon and fresh herbs like dill. Add in some creamy goat cheese and this is ready in no time in one skillet.

What Should I Serve With These Roasted Green Beans with Garlic and Lemon?

These roasted green beans are the perfect side dish for a variety of proteins. We love to pair these roasted green beans with garlic and lemon with our Keto Bacon Wrapped Brown Sugar Chicken, since the chicken is so sweet and rich, these green beans make the ideal light side.

This Low Carb Citrus Glazed Salmon is also a wonderful option, and the strong flavors of lemon and garlic will marry perfectly with the sweet orange citrus notes, and earthy shallots. Another great option would be these Crispy Baked Chicken Wings for a lighter side that pairs perfectly with these delicious wings.

We’d also like to suggest eating these green beans with anything BBQ related, like these Baked Ribs, Keto Maple BBQ Glazed Shrimp or this Keto BBQ Bacon Cheeseburger to balance out the rich, sweet flavors found in these meals. All three of these proteins are made with this Spicy Bourbon Homemade Sugar Free BBQ Sauce, which is a rich, sweet, spicy and flavorful homemade keto friendly BBQ sauce recipe!

How Do I Prepare These Green Beans?

To trim: Trimming green beans for this recipe is so easy. You can simply remove the tough ends or brown bits with a sharp knife, or sometimes even your fingers. Twist off the fibrous ends with your fingertips.

Roasting: Roasting these green beans is probably the easiest way to cook them, since there is so much inactive time for you to work on cleaning up the kitchen or preparing the rest of your meal. Who doesn’t like more time to do something else? These green beans are roasted at quite a high heat, and. the 400°F helps this dish come together quick. We do recommend tossing the beans halfway through cooking time (about 10 minutes) and giving it a quick toss to ensure even cooking.

adding melted butter to minced garlic

Prepping the garlic: We minced our garlic up pretty small for this application. This was an attempt to coat the roasted green beans with as much garlic as possible. Use a garlic press, a microplane, or a sharp knife to get it really small. Garlic is one of the main flavors for this simple side dish, so use as much as you prefer. We are quite enthusiastic about garlic, and used about 5 large cloves. Be warned that adding garlic adds carbs if you are concerned with that.

Butter or Oil: You could use any combination of these two fats. Sometimes a mix of both for flavor. Our recommendation would be to melt your butter beforehand so you can combine it with lemon juice, garlic and your salt prior to mixing it with your green beans. This simply ensures more even coating of the green beans.

Lemons: utilize as much lemon as you want for this! We used the juice in two ways. Some of the juice goes into your butter mixture before cooking, and the rest of the lemon juice we add later to garnish and to taste after charring the lemon juice. Adding different flavor layers is not only delicious, beautiful and fun, but it also allows you to adjust the flavor a bit so you can customize.

How and Why Should I Char the Lemons?

Charring lemons or grilling them is such a simple way to elevate this dish and make it look beautiful! Charring the lemons gives it an added sweetness and extra flavor, as well as helps release some of the juices, which maximizes the amount of lemon juice you can extract from the fruit. To char the lemons, you can simply heat up a cast iron griddle or grill pan over medium heat until it is quite hot.

Cut your lemons in half widthwise, and then brush the halves with some olive oil or avocado oil. We like to brush the lemon halves with oil to ensure they don’t stick to your griddle pan or grill. Make sure your cast iron griddle is well oiled as well. Add your lemon halves with the fruit side down to the pan and allow it to sit for about 3-5 minutes, until there are some nice grill marks. You can re-position the lemon halves and repeat the process if you want more grill marks.

  • Garlic- Use garlic powder for an even quicker assembly. You don’t have to worry as much about the cooking time either, since garlic powder will not burn like fresh garlic.
  • Butter– If you are dairy free, you could easily just swap butter for olive oil or avocado oil.

How to Make Roasted Green Beans with Garlic and Lemon:

We’d recommend roasting these green beans at a pretty high heat to make them cook quickly! We preheated our oven to 400°F, and only needed about 20 minutes until these green beans were roasted to perfection. Start by cleaning and prepping your green beans, then mincing up your garlic really fine. Get your lemon juice ready and melt your butter.

Add your cleaned green beans to your cast iron skillet. In a bowl, combine your minced garlic, salt, and the fresh lemon juice. Add to your lemon garlic butter to your beans, and combine well. Place in the oven for about 20 minutes, until your beans are cooked to your liking. Give the beans a stir about halfway thru to ensure even cooking.

When the beans are in the oven, heat your griddle over medium heat until it’s quite hot. Cut your lemons in half, and brush with some oil before adding them to your hot griddle.

Cook for 2-3 minutes until you achieve some nice grill marks, then set aside until it’s time to garnish your green beans when you’re finished!
