Whether you’re following Whole30 or simply want a quick, flavorful weeknight meal, this Spicy Beef Stir Fry is a reliable go-to. Ready in about 15 minutes with a handful of ingredients, it delivers bold taste and works beautifully over cauliflower rice for a low-carb option.
The key to a successful stir fry is preparation: wash, slice and measure everything before the pan heats up. This mise en place approach keeps the cooking process fast and smooth so nothing burns while you chop. Stir fries are cooked quickly over high heat, so having all ingredients ready is essential.
This recipe is highly adaptable—use whatever vegetables you have on hand. Try celery, bok choy, cashews, green bell peppers, or mushrooms. Just avoid overcrowding the pan; too many ingredients at once will trap steam and prevent proper browning. High heat is crucial: it creates caramelization and deep flavor on both the meat and vegetables. Cooking on lower heat causes moisture to build, leading to steaming instead of stir-frying. Professional woks use extremely high BTU burners for a reason—your stove won’t match those temperatures, so choose a cookware and technique that maximize the heat you do have.
Pick a pan that tolerates high temperatures—carbon-steel, cast-iron or stainless steel are ideal. Avoid non-stick pans for this dish, as many non-stick coatings degrade at very high heat.
For cookware recommendations, quality stainless-steel and carbon-steel pans offer durability and better heat performance for stir-frying. Cast-iron skillets such as the well-known, affordable models are also an excellent choice for achieving a good sear and even heat distribution.

Spicy Beef Stir Fry – Whole30, Paleo
Ingredients
- 1/3 cup coconut aminos
- 1 teaspoon arrowroot starch
- ½ pound beef steak of choice, such as top sirloin, flat-iron, bavette, Denver, skirt, flank, or inside round, thinly sliced
- 2 tablespoons avocado oil
- 1 medium carrot, julienned
- 1 red bell pepper, julienned
- 1 spicy red chili pepper, such as Fresno
- ½ medium red onion, thinly sliced
- 1 clove garlic, finely chopped
- 1 teaspoon sesame oil
Instructions
-
In a bowl, whisk the coconut aminos and arrowroot starch until smooth. Add the steak and toss to coat. Cover and let marinate for 15 minutes or up to 1 hour.
-
Preheat a large cast-iron or carbon-steel pan over medium-high heat for about 5 minutes, then turn the heat to high. Add the avocado oil and heat until it shimmers. Reserve the marinade and drain as much of it from the beef as possible. Carefully add the beef to the hot oil (it will splatter) and cook undisturbed until browned, about 2 minutes. Flip and brown the other side, about 1 minute. Transfer the beef to a bowl and set aside.
-
Reduce the heat to medium-high and add the carrot, bell pepper, chili pepper, and onion. Stir-fry until slightly softened, about 2 minutes. Add the garlic and cook for another 60 seconds. Pour in the reserved marinade and the sesame oil, stirring regularly for 2 minutes. Return the beef to the pan and toss to coat.
-
Serve immediately with cauliflower rice and enjoy.
