Cajun Blistered Green Beans
You may have tried steamed or sautéed green beans. You might have even roasted them like in Roasted Green Beans and Carrots or Roasted Green Beans and Brussels Sprouts, but have you tried blackened green beans?
This is my new favorite green beans recipe! Green beans are blistered in a hot cast iron skillet, then tossed with butter and blackening seasoning. Blackening is a technique usually applied to proteins, like Blackened Chicken or Blackened Salmon, but you can use it on vegetables too for a delicious side dish!

Ingredients & Substitutions
See the recipe card below for the complete list of ingredients and measurements.
- Fresh green beans - It is best to use fresh green beans for this recipe. Canned or frozen green beans won’t blister like fresh ones will.
- Avocado oil - I use avocado anytime I am cooking with a very high heat, like most of my blackened recipes, since avocado oil has a high smoke point. You can substitute for olive oil.
- Yellow onion - You can substitute for sweet onion, white onion, shallot, or red onion.
- Garlic - Use fresh garlic! It is so much more flavorful than the jarred kind.
- Blackening seasoning - A Cajun spice blend with cayenne pepper, black pepper, onion and garlic powder, and other spices and dried herbs. You can purchase blackening seasoning in the spice aisle of the grocery store, but I highly recommend you make your own homemade blackening seasoning! Homemade has less salt, but way more flavor. You can substitute for Cajun seasoning if needed.
How to Make Blistered Green Beans
Step One: Prep
Wash and completely dry green beans. Chop into bite size pieces.
Step Two: Blister
Add oil to a HOT skillet, then add green beans. Leave undisturbed until blackened on one side.
Step Three: Sauté
Turn heat down lower. Add in onions to sauté, then add in garlic.
Step Four: Finish
Add in butter and blackening seasoning. Toss to coat. Serve topped with parsley and a squeeze of lemon.
Expert Tips for Blackened Green Beans
- Adjust the spice. This recipe is only mildly spicy, but if you don’t like spice, use less or omit the cayenne pepper in your blackening seasoning.
- Big skillet. For best results, use a large skillet so the green beans have more surface area available to get blackened.
- HOT pan. Make sure your skillet is fully heated before adding the green beans so they can become blackened and blistered.
- NO moisture. Dry green beans thoroughly with paper towels before adding to the hot pan, or moisture will cause the oil to splatter.

Frequently Asked Questions
No, it is not necessary to blanch or boil green beans before sautéing them. The high heat needed to blister the green beans will also make them perfectly cooked, but still keep a firm texture.
No, blackened food does not mean burnt. Blackening refers to the cooking technique of coating foods in a blackening spice mix, then searing at a high heat to achieve a flavorful blackened crust.
Green beans pair well with the flavors of onions, garlic, basil, parsley, thyme, tomatoes, soy sauce, sesame oil, and bacon. I like using cajun seasoning or blackening seasoning on them for extra flavor.
