  • 1 pound Brussels sprouts trimmed and halved
  • 4 slices bacon
  • 2 tsp balsamic vinegar
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 1 pinch crushed red pepper flakes optional
  • 1/4 cup fresh grated parmesan


  • Cook bacon over medium heat until crisp, then set aside to cool. Reserve fat (about 1.5T).
  • Add Brussels sprouts, reserved bacon fat, and balsamic vinegar to a large bowl and toss to coat. Season with salt, pepper, garlic powder, and red pepper.
  • Transfer seasoned sprouts to air fryer, and cook at 400F for 6 minutes. In the meantime, coarsely chop bacon.
  • Add chopped bacon to Brussels sprouts and gently toss to combine. Air fry for an additional 4-5 minutes, or until desired tenderness.
  • Transfer keto Brussels sprouts to serving dish, and top with parmesan. Serve immediately, with an additional drizzle of balsamic vinegar if desired.


  • Storage: Store refrigerated in a sealed container for up to 4 days.
  • Reheating: For optimal results, reheat in the air fryer to maintain crispness. A microwave works too, but you'll lose the crisp edges.
  • To make this keto Brussels sprouts recipe in the oven, preheat oven to 425F and prepare a baking sheet by lining with parchment paper. Prep sprouts as directed, then bake for 25-30 minutes. Add the bacon about 15 minutes into the bake time.
