Green beans are one of my favorite veggies! And these crispy roasted greens beans are a new favorite around here! They’re so simple and easy, it’s hard for me to actually call this a recipe. My favorite part is that there’s no blanching or precooking required – just toss them with the rest of your ingredients and you’re good to go! They’re cheesy, garlicky and so flavorful that even the pickiest eaters will love them! These are the best crispy roasted green beans!

Growing up, we’d always boil/blanch our green beans first, but I love that these garlic parmesan green beans are made in the oven! Not only are the beans perfectly cooked, but the parmesan becomes so crispy and delicious – ohhh it’s just the best! They’re so addicting, I can pop them in my mouth like candy!

Ingredients used to make garlic parmesan roasted green beans

Ingredients For Your Roasted Green Beans

  • Green beans: Look for beans that are firm and green with no brown spots for the best results. You’ll need 1 – 1½ pounds for this recipe!
  • Garlic: You’ll need about 6 large garlic cloves.
  • Parmesan cheese: We’ll usually buy a block of parmesan and shred it ourselves. (It’s so much more flavorful than pre-shredded cheese!) Store bought shredded or grated parmesan can be used instead though.
  • Oil: I always recommend using avocado oil for roasting veggies. (It has a higher smoking point meaning it can crisp up your veggies at a higher temperature without burning them.) Olive oil can be used instead!
  • Spices: Salt and black pepper are all that’s needed!
  • Lemon: Optional – A little squeeze over the top of your beans after roasting really elevates their flavor!

How To Make Garlic Parmesan Green Beans

1. Prep your oven. Turn your oven on to 400 degrees and line a large baking pan with parchment paper. (You might need 2 pans depending on how many green beans you have and the size of your oven.)

2. Prep your green beans. Trim both ends off your green beans and place them in a large bowl. (We’ll usually snap the ends off with our hands but using a knife to cut them works too.)

3. Toss. Add your green beans, oil, garlic, parmesan, salt and pepper to a bowl and toss until fully coated.

4. Roast. Then pour your green beans onto your prepared baking pan and spread them out in a single layer. (It’s ok if a few beans are overlapping.) Place them in the oven and roast for 15-20 minutes.

5. Serve! Squeeze a little lemon over the top (if desired) and serve immediately!

FAQ’s

Do I have to trim my green beans? Yes. The ends can get a little tough after roasting so I always suggest trimming them beforehand.

Can I use frozen green beans? Yes! Simply toss your frozen green beans with the rest of your ingredients and prepare them according to the directions. There’s no thawing required!

I don’t have parmesan! Is there a different cheese I can use? Absolutely! Pecorino Romano or Asiago would be great substitutes!

Ingredients

  • 1 – 1½ lbs. green beans
  • 2 Tbsp avocado oil (or olive oil)
  • 6 garlic cloves
  • ¼ cup grated parmesan
  • ½ tsp salt*
  • ½ tsp black pepper
  • Lemon, to squeeze over the top (optional)

Instructions

  • Turn your oven on to 400 degrees and line a large baking pan with parchment paper. (You might need 2 pans depending on how many green beans you have and the size of your oven.)
  • Trim both ends off your green beans and place them in a large bowl. (We'll usually snap the ends off with our hands but using a knife to cut them works too.)

  • Squeeze a little lemon over the top (if desired) and serve immediately!

Notes

Every oven is different so I would suggest checking your beans around 10-12 minutes to see how much longer they’ll need to roast.
If you’re using 2 pans or overcrowded your pan, the beans may take longer than the suggested amount of time to cook.
*A few of my family members preferred less salt in this dish (because the parmesan itself is pretty salty). If you prefer less salt I would suggest starting with a ¼ teaspoon and adding salt to taste (if needed) after the beans are roasted.
