How to Make the Best Keto Beef Stir-Fry in 25 Minutes

The Keto Beef Stir-Fry is a quick and flavorful dish that brings together the best of Asian-inspired cooking with keto-friendly ingredients.

Stir-frying as a cooking technique dates back thousands of years to China, where it was developed as a fast and efficient way to cook food using minimal oil over high heat. The practice spread across Asia, and today, stir-frying is loved globally for its ability to preserve the flavors and textures of fresh ingredients.

This keto version focuses on lean, tender strips of beef and low-carb vegetables like broccoli, bell peppers, and zucchini, all coated in a savory stir-fry sauce made with keto-friendly ingredients such as soy sauce, sesame oil, and garlic. Unlike traditional stir-fries, which may use higher-carb ingredients like cornstarch for thickening or sugary sauces, this recipe keeps it keto by using alternatives that won’t spike blood sugar levels.

Stir-fry dishes have always been popular for weeknight dinners due to their quick preparation, and this keto version stays true to that tradition. It’s a satisfying mix of protein and vegetables, perfect for those who want to enjoy a flavorful, hearty meal while sticking to a low-carb, high-fat keto diet.

A fun fact is that the word “stir-fry” was actually coined in the mid-20th century to introduce the Chinese cooking technique to Western audiences. Today, it’s a staple in kitchens worldwide, loved for its versatility and speed. This Keto Beef Stir-Fry embraces that spirit, offering a nutritious, tasty meal that can be whipped up in just 25 minutes!

Cook Mode Cooking Mode Disabled

Beef and Vegetables:

• 1 lb beef sirloin or flank steak, thinly sliced
• 1 tbsp coconut oil or olive oil
• 1 bell pepper (red or green)
• 1 cup broccoli florets
• 1 medium zucchini, sliced
• 1 cup sliced mushrooms
• 3 cloves garlic, minced
• 1 tbsp fresh ginger, minced

Stir-Fry Sauce:

• ¼ cup soy sauce or coconut aminos
• 2 tbsp rice vinegar
• 1 tbsp sesame oil
• 1 tsp chili paste (optional, for heat)
• 1 tsp powdered erythritol or monk fruit sweetener (optional)
• 1 tbsp water

Instructions

Prepare the Sauce:

1. In a small bowl, whisk together soy sauce (or coconut aminos), rice vinegar, sesame oil, chili paste (if using), powdered erythritol, and water. Set aside.

Cook the Beef:

1. Heat 1 tbsp of coconut oil or olive oil in a large skillet or wok over medium-high heat. Add the sliced beef and cook for 2-3 minutes, until browned. Remove from the skillet and set aside.

Cook the Vegetables:

1. In the same skillet, add more oil if needed. Add the minced garlic and ginger and sauté for about 30 seconds until fragrant.
2. Add the sliced bell pepper, broccoli florets, zucchini, and mushrooms. Cook for 4-5 minutes, stirring frequently, until the vegetables are tender but still crisp.

Combine and Serve:

1. Return the cooked beef to the skillet and pour in the stir-fry sauce. Stir well to coat the beef and vegetables, and cook for an additional 2-3 minutes, until everything is heated through and the sauce slightly thickens.
2. Serve hot, optionally garnished with sesame seeds and sliced green onions.

Note

Vegetable Options: You can add or substitute other low-carb vegetables like bok choy, snow peas, or cauliflower to add more variety.

Marinate the Beef: For extra flavor, marinate the beef in half of the stir-fry sauce for 15 minutes before cooking. Just remember to discard the marinade before cooking.

Serve With: Serve this keto beef stir-fry on its own or over cauliflower rice for a more filling meal.
