Simple ingredients often make the most memorable meals, and this recipe is no exception. Each component plays an essential role, whether it’s creating layers of flavor, adding crunch, or ensuring the dish meets your keto goals perfectly.

- 1/2 lb Broccoli (cut into small florets): Adds a vibrant green color and crisp texture, bringing freshness to the dish.
- 1/4 cup Coconut Oil: A healthy fat that cooks the beef perfectly and enhances the keto profile.
- 1 tsp Toasted Sesame Oil: Provides a rich, nutty aroma that elevates every bite.
- 1 tsp Fish Sauce: Adds an umami depth without overpowering the natural flavors.
- 1/4 cup Coconut Aminos: A savory and slightly sweet soy sauce alternative that’s keto-friendly.
- 1 tsp Fresh ginger (peeled and grated): Offers a zesty kick that brightens the beef marinade.

How to Make Keto Low Carb Beef and Broccoli Recipe
Step 1: Prep Your Ingredients
Start by slicing your flat iron steak thinly against the grain to ensure tender bites, and cut the broccoli into small, manageable florets so they cook evenly. This prep work sets a solid foundation for the flavors and textures to shine.
Step 2: Marinate the Beef
In a mixing bowl, combine the sliced steak with coconut aminos, freshly grated ginger, and chopped garlic. Allowing the beef to marinate for at least an hour infuses it with a vibrant, savory punch that carries through the entire dish.
Step 3: Blanch the Broccoli
To keep your broccoli bright green and maintain a perfect crunch, blanch it in boiling water for two minutes. Drain immediately to stop the cooking process—it’s the little tricks like this that make a big difference.
Step 4: Cook the Beef
Heat coconut oil in a wok or large skillet over medium-high heat. Stir-fry the marinated beef for just 1 to 3 minutes until it’s nicely browned on the outside but still juicy inside. Once cooked, set the beef aside to keep it perfectly tender while you move on to the broccoli.
Step 5: Stir-Fry the Broccoli and Marinade
Using the same skillet, stir-fry your blanched broccoli for about 3 minutes until crisp-tender. Pour in any remaining marinade and cook for another two minutes to marry all those wonderful flavors together.
Step 6: Combine and Finish
Return the beef to the pan and add fish sauce and toasted sesame oil. Give everything a thorough mix so every bite is coated with a delightful balance of flavor and texture. Serve hot and garnish with freshly chopped parsley for a burst of green freshness.
How to Serve Keto Low Carb Beef and Broccoli Recipe

Garnishes
Fresh parsley adds a lovely pop of color and a mild herbal brightness. If you want to experiment, a sprinkle of toasted sesame seeds or sliced green onions can add a nice crunch and visual appeal.
Side Dishes
This recipe shines on its own as a hearty meal, but pairing it with Cauliflower Rice or Shirataki noodles keeps things low carb while offering a great way to soak up the tasty sauce.
Creative Ways to Present
For a fun twist, serve the beef and broccoli over crispy baked kale chips for added texture, or create colorful lettuce wraps to keep your meal fresh and finger-friendly. Presentation is all about celebrating the vibrant colors and inviting aromas.
Make Ahead and Storage
Storing Leftovers
Place any leftover beef and broccoli in an airtight container and refrigerate. It will stay fresh for up to three days, making it perfect for quick weekday lunches or dinners.
Freezing
This dish freezes well. Divide portions into freezer-safe containers or bags and freeze for up to two months. Thaw overnight in the fridge before reheating.
Reheating
Reheat your leftovers gently in a skillet over medium heat with a splash of water or oil to keep the beef moist and broccoli crisp. Avoid microwaving for best texture retention.
FAQs
Can I use a different cut of beef?
Absolutely! While flat iron steak is tender and flavorful, sirloin or flank steak also work well if sliced thinly against the grain.
Is this recipe suitable for strict keto diets?
Yes, it’s ideal for keto diets because it uses low-carb ingredients and healthy fats without any sugar-laden sauces.
Can I substitute broccoli with other vegetables?
Definitely! Green beans or asparagus make great alternatives and keep the dish low carb while adding their own unique crunch.
How long should I marinate the beef?
At least one hour is best to let the flavors really penetrate, but if you’re short on time, even 30 minutes will still add good flavor.
What if I don’t have coconut aminos?
While coconut aminos add a subtle sweetness, tamari or soy sauce can be used as substitutes if you’re not avoiding soy, keeping in mind they may alter the flavor slightly.
Final Thoughts
I can’t recommend this Keto Low Carb Beef and Broccoli Recipe enough if you want something fast, flavorful, and perfectly keto-friendly. It’s one of those dishes that feels gourmet but comes together with everyday ingredients and minimal fuss. Give it a try and watch it become your go-to weeknight favorite!
