Ingredients You’ll Need

What’s wonderful about this Keto Low Carb Beef And Broccoli is that you only need a handful of thoughtfully chosen ingredients—each one pulling its weight in terms of texture, aroma, and mouthwatering flavor. Here’s what you’ll need to bring this dish to life:

Flat Iron Steak: Sliced thinly against the grain for that perfect melt-in-your-mouth bite and maximum tenderness in every forkful.
Broccoli: Cut into small florets so they cook quickly and soak up all the delicious sauce—you want those edges just a little crispy!
Coconut Oil: For high-heat stir-frying; it adds a subtle, lush richness and keeps everything from sticking.
Toasted Sesame Oil: Just a touch for an irresistible nutty finish that brings all the flavors together beautifully.
Fish Sauce: A little goes a long way for adding complexity and that signature savory depth you love in Asian-inspired dishes.
Coconut Aminos: The secret to keeping it low carb, with a naturally sweet and salty taste that binds the sauce.
Root Ginger: Freshly grated is a must—never powdered! It adds a bright, spicy warmth and complexity you can’t fake.
Garlic: Chopped for a bold, aromatic punch that infuses the steak and broccoli throughout.

How to Make Keto Low Carb Beef And Broccoli

Step 1: Slice and Marinate the Steak

Thinly slicing the flat iron steak against the grain is key for tenderness—that way, every bite is juicy and easy to chew. Add your beef slices to a small bag with coconut aminos, freshly grated ginger (trust me, skip the powdered stuff), and chopped garlic. Let the flavors mingle for an hour in the fridge; this quick marinade infuses the steak with rich, aromatic flavor and helps keep it extra juicy during cooking.

Step 2: Prepare the Broccoli

While the steak marinates, cut your broccoli into small, even florets. Give them a two-minute blanch in boiling water, just until they turn a vivid green and start to soften. Drain well; excess water is the enemy of a good stir fry, so make sure they’re as dry as possible before hitting the skillet.

Step 3: Brown the Beef

After your steak has soaked up all those delicious flavors, drain it—making sure to reserve the marinade. Heat coconut oil in a large wok or cast iron skillet until shimmering, then sear the beef in a hot pan. Work in batches if needed to avoid steaming. This step should only take about 1 to 3 minutes, just until the slices are browned and just cooked through. Remove them from the pan quickly to keep them from overcooking.

Step 4: Stir-Fry Broccoli and Sauce

Toss your drained broccoli florets into the same pan and stir-fry until they’re crisp-tender and just beginning to char at the edges—that’s flavor! Add the reserved marinade and cook for about two more minutes, letting the sauce thicken and coat every little green crevice.

Step 5: Finish and Serve

Return your beautifully browned steak to the pan, mixing to combine. Finish with fish sauce and just a drizzle of toasted sesame oil for a glossy, aromatic finish. Serve your Keto Low Carb Beef And Broccoli hot, ideally with all those flavors mingling and filling your kitchen with the most mouthwatering aroma.

How to Serve Keto Low Carb Beef And Broccoli

Garnishes

A sprinkle of freshly chopped scallions or a dusting of toasted sesame seeds adds color and texture, while a few red pepper flakes will bring a gentle heat for anyone craving a spicy kick. Don’t forget an extra drizzle of sesame oil just before serving for unbeatable aroma.

Side Dishes

While perfectly satisfying all on its own, Keto Low Carb Beef And Broccoli loves hanging out with cauliflower rice or a pile of quick-sauteed bok choy. The dish also pairs nicely with shirataki noodles if you want to keep things deeply low carb but still have that classic takeout vibe.

Creative Ways to Present

For a fun twist, serve your beef and broccoli straight from the skillet at the table, or scoop it into lettuce leaves for hand-held wraps. You can also pile it high in individual bowls with different toppings for a DIY stir fry night—a surefire crowd-pleaser!

Make Ahead and Storage

Storing Leftovers

Store any leftover Keto Low Carb Beef And Broccoli in an airtight container in the fridge. It will stay fresh for up to three days, making it a smart option for meal prep or next-day lunches. Just be sure the broccoli is cooled completely before sealing to keep it from getting mushy.

Freezing

This dish is surprisingly freezer-friendly! Portion the cooked and cooled beef and broccoli into freezer bags, squeezing out as much air as you can before sealing. Lay flat in the freezer for up to two months; the flavors keep beautifully, and the steak stays tender after thawing.

Reheating

For the best texture, reheat leftovers in a skillet over medium heat, adding a splash of water or extra coconut aminos if needed to loosen up the sauce. Microwave reheating will work in a pinch—just give it a stir halfway through so everything heats evenly.

FAQs

Can I use another cut of beef instead of flat iron steak?

Absolutely! Flank steak or sirloin also work great in this recipe, just be sure to slice the meat thinly against the grain for maximum tenderness and fast, even cooking.

Is Keto Low Carb Beef And Broccoli spicy?

Not inherently—but it’s easy to spice things up! Feel free to add chili flake, a dash of hot sauce, or sliced red chiles during the stir fry step if you like some heat in your meal.

Can I substitute coconut aminos with something else?

If you’re not strictly keto, low-sodium tamari or soy sauce can work, but coconut aminos keep it gluten-free and add a subtle sweetness while keeping the carb count very low.

How can I make Keto Low Carb Beef And Broccoli vegetarian?

Swap out the beef for thinly sliced portobello mushrooms or extra-firm tofu (pressed and pan-fried) and use mushroom or vegetarian ‘fish’ sauce alternatives. You’ll still get those rich flavors and hearty textures!

Is blanching the broccoli really necessary?

It’s a quick step, but worth it! Blanching locks in the vibrant green color and ensures the broccoli is tender but never mushy once it hits the hot pan.
