This Cajun Blackened Green Beans recipe features fresh green beans pan-seared in avocado oil and blackening seasoning for a smoky, spicy flavor. Finished with sautéed onions, garlic, and butter, these green beans make a flavorful side dish with an optional touch of lemon and parsley for freshness.

Ingredients

Main Ingredients

  • 1 pound fresh green beans (trimmed and cut into 2 inch pieces)
  • 1 tablespoon avocado oil
  • ⅓ cup finely chopped yellow onion
  • 2 cloves garlic (minced)
  • 2 teaspoons blackening seasoning
  • 1 tablespoon unsalted butter
  • Lemon (optional, for serving)
  • Fresh parsley (optional, for garnish)

Instructions

  1. PREP: Wash and trim the green beans, cutting them into 2 inch pieces. Dry thoroughly to ensure proper searing. Heat a cast iron or heavy skillet over medium-high heat for a few minutes to get it hot.
  2. BLISTER: Add the avocado oil to the skillet and swirl to coat the surface evenly. Add the green beans in a single layer if possible and do not stir for at least 3 minutes. Let the undersides blacken, then flip the green beans over. Continue cooking for about 10 minutes in total, until all green beans are blackened and tender yet still crisp.
  3. SAUTÉ: Reduce the heat to medium and add the finely chopped yellow onions to the pan. Sauté for 2 to 3 minutes until the onions soften, stirring occasionally. Add minced garlic and stir for about 1 minute until the garlic becomes fragrant.
  4. FINISH: Add the unsalted butter and blackening seasoning to the pan. Toss everything together to coat the green beans well. Taste and add salt if needed to balance the flavors.
  5. SERVE: Serve the blackened green beans warm with an optional squeeze of fresh lemon juice and garnish with chopped fresh parsley for a bright finish.

Notes

  • Ensure green beans are dry before cooking to get a proper blackened sear.
  • If you don’t have blackening seasoning, a mixture of paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, and pepper can be used.
  • Cast iron skillet is ideal for best heat retention and even blackening.
  • For a vegan option, substitute butter with a plant-based alternative or additional oil.
  • Lemon juice brightens the dish but is optional based on preference.
  • Parsley adds freshness and a pop of color, but can be omitted if unavailable.
