Air Fryer Green Beans and Mushrooms - Simple, Savory, and Ready Fast

Prep Time10 minutes
Cook Time12 minutes
Total Time22 minutes
Servings: 4 servings

Ingredients

  • Fresh green beans (12–16 ounces), trimmed
  • Cremini or button mushrooms (8 ounces), cleaned and halved or quartered
  • Olive oil (1.5–2 tablespoons)
  • Garlic (2–3 cloves), minced, or 1 teaspoon garlic powder
  • Salt (kosher or sea salt)
  • Black pepper, freshly ground
  • Onion powder (optional, 1/2 teaspoon)
  • Red pepper flakes (optional, a pinch)
  • Lemon (zest and juice, optional but recommended)
  • Grated Parmesan (optional, for serving)
  • Fresh herbs such as parsley or thyme (optional)
  • Sliced almonds or chopped walnuts (optional, for crunch)

Instructions

  • Preheat your air fryer to 380°F (193°C) for 3–5 minutes. A hot basket helps vegetables brown better.
  • Prep the vegetables: Trim the ends off the green beans. Rinse the mushrooms and pat them very dry. Halve or quarter larger mushrooms so everything is similar in size for even cooking.
  • Season in a bowl: Toss green beans and mushrooms with olive oil, minced garlic (or garlic powder), salt, pepper, and onion powder if using. Add a small pinch of red pepper flakes for mild heat.
  • Don’t overcrowd: Add the vegetables to the air fryer basket in a single layer. If your air fryer is small, cook in two batches for the best sear.
  • Air fry for 8 minutes, then shake the basket or toss with tongs to move the vegetables around. This helps them brown evenly.
  • Cook 3–6 minutes more, until green beans are crisp-tender and mushrooms are browned. Total time is usually 11–14 minutes, depending on your air fryer and how well-done you like them.
  • Finish with brightness: Transfer to a bowl and add lemon zest and a squeeze of juice. Taste and adjust salt and pepper. For richness, sprinkle with Parmesan or a drizzle of good olive oil.
  • Optional crunch: Toast nuts in a dry skillet for 2–3 minutes and toss over the top right before serving.
