A flavorful and quick Keto Beef and Bell Pepper Stir-Fry featuring tender flank steak and crisp vegetables, perfect for a low-carb dinner.

Ingredients

Meat

  • 1 lb flank steak, sliced thinly against the grain

Vegetables

  • 1 bell pepper, sliced
  • 1 medium onion, sliced
  • 3 cloves garlic, minced

Oils and Sauces

  • 2 tablespoons coconut oil (or olive oil)
  • 1 tablespoon soy sauce (or tamari for gluten-free)
  • 1 tablespoon oyster sauce (optional)

Seasonings and Garnish

  • Salt and pepper to taste
  • Sesame seeds (for garnish)
  • Green onions, sliced (for garnish)

Instructions

  1. Heat the oil: Heat coconut oil in a large skillet or wok over medium-high heat until shimmering.
  2. Cook the beef: Add the sliced flank steak and cook for about 3-4 minutes, stirring occasionally until browned on all sides. Remove the beef and set aside.
  3. Stir-fry vegetables: In the same skillet, add the sliced bell pepper, onion, and minced garlic. Stir-fry for 3-4 minutes until vegetables are tender-crisp.
  4. Combine ingredients: Return the cooked beef to the skillet with the vegetables. Stir in soy sauce, oyster sauce, salt, and pepper.
  5. Finish cooking: Cook everything together for an additional 2-3 minutes until the beef is heated through and flavors meld.
  6. Garnish and serve: Remove from heat, garnish with sesame seeds and sliced green onions, then serve hot.

Notes

  • Use tamari instead of soy sauce to make the dish gluten-free.
  • Oyster sauce is optional but adds umami flavor; substitute with a gluten-free alternative if needed.
  • Slice the flank steak thinly against the grain for maximum tenderness.
  • If you prefer, substitute coconut oil with a neutral oil like avocado or olive oil.
  • Adjust the level of garlic according to your taste preference.
