What Is the Ketogenic Diet?
The ketogenic diet is a nutritional approach that flips the script on your body’s fuel system.
By keeping total carbohydrates extremely low (typically under 30 grams net carbs per day), upping healthy fats, and moderating protein, your body transitions from burning glucose to burning fat-derived ketones for energy. The result?
Steadier blood sugar, improved fat-burning, stable energy, and often a surprising reduction in cravings.
- High Fat (70–80% of calories): Keeps you satiated and supports ketone production.
- Moderate Protein (15–25%): Preserves muscle without converting excess protein into glucose.
- Low Carbs (5–10%): Forces the metabolic shift into ketosis.
Traditional Beef and Broccoli can derail ketosis thanks to sugar-heavy sauces and starchy thickeners. Our keto version slashes those hidden carbs, so you indulge in every savory bite without the guilt.
Why Beef and Broccoli Belongs on Your Keto Menu
- Broccoli’s Low Net Carbs & High Fiber
- One cup of cooked florets has roughly 6 g total carbs and 3 g fiber, yielding only 3 g net carbs—perfect for keeping your daily count low.
- Packed with vitamins C, K, and folate, plus antioxidants that support overall health.
- Beef’s Protein Punch & Nutrient Density
- Lean cuts like flap steak or flat-iron deliver about 25–30 g of protein per 4-oz serving, helping maintain muscle mass.
- Rich in iron, B-vitamins, and zinc—key nutrients often found on restricted diets.
- Flavor & Satisfaction
- The umami-rich beef, garlic, and ginger meld into a deeply savory sauce that satisfies cravings.
- A one-pan stir-fry means minimal cleanup and maximum dinner satisfaction.
Ingredient Table
| Ingredient | Amount | Notes / Keto Swap |
|---|---|---|
| Flank steak or flat-iron steak | 1 lb (450 g), thinly sliced | Slice against the grain for tenderness |
| Broccoli florets | 4 cups (approx. 300 g) | Blanch 1–2 minutes before stir-fry |
| Coconut aminos | ⅓ cup (80 ml) | Lower-sugar substitute for soy sauce |
| Garlic | 4 cloves, minced | Fresh for the best flavor |
| Fresh ginger | 1 Tbsp, grated | Adds a bright, spicy note |
| Avocado or sesame oil | 2 Tbsp | High-smoke-point oil for stir-frying |
| Xanthan gum | ½ tsp | Low-carb thickener in place of cornstarch |
| Water or beef broth | ¼ cup (60 ml) | To dissolve xanthan gum into a slurry |
| Toasted sesame oil | 1 tsp | Finishing drizzle for aroma |
| Sesame seeds (optional) | 1 Tbsp | For garnish |
| Red pepper flakes (optional) | Pinch | If you like a touch of heat |
Preparation & Cooking
1. Prep the Beef
- Freeze briefly (15–20 minutes) to make ultra-thin slicing easier.
- Slice thinly against the grain (aim for ⅛–¼ inch thickness) for the most tender bite.
- Marinate: Toss sliced beef with 2 Tbsp coconut aminos, half the garlic, and half the ginger. Let rest 10 minutes while you prep broccoli.
2. Prep the Broccoli
- Cut into small, even florets.
- Blanch: Bring a pot of salted water to a boil. Add broccoli for 1–2 minutes until bright green and just tender.
- Shock in an ice bath to halt cooking, then drain thoroughly. This step ensures crisp-tender florets that stand up to high-heat stir-frying without turning soggy.
3. Make the Sauce Slurry
- In a small bowl, whisk together:
- Remaining 1⁄3 cup coconut aminos
- ½ tsp xanthan gum
- ¼ cup water or broth
- Remaining garlic and ginger
- Stir until xanthan gum is fully dispersed and no lumps remain.
4. Stir-Fry Technique
- Heat your wok or skillet over high heat until hot (a drop of water should sizzle away instantly).
- Add 1 Tbsp oil, swirl to coat.
- Cook beef in batches: Lay slices flat, let sear undisturbed for 30 seconds, then toss and cook 1 minute more until just browned. Transfer to a plate.
- Add remaining oil. Give the pan a moment to reheat, then add broccoli. Toss 30 seconds.
- Pour sauce slurry over broccoli, stir until it begins to thicken—about 20 seconds.
- Return beef (and any accumulated juices) to the pan, toss everything together for another 30 seconds until the beef is coated in a glossy sauce.
- Finish with sesame oil and sprinkle with sesame seeds and red pepper flakes if desired.
Serving Suggestions & Variations
- Over Cauliflower Rice: For a complete keto bowl, pile steaming cauliflower rice beneath your stir-fry.
- Spicy Kick: Add 1 tsp of Sriracha or chili garlic sauce to the marinade.
- Protein Swap: Use thinly sliced chicken breast or pork tenderloin if you’re avoiding red meat. Adjust cooking times to keep meat juicy.
- Veggie Variations: Swap half the broccoli for sliced zucchini, shredded cabbage, or snap peas—just adjust blanching times.

Chef’s Tips for Flawless Keto Beef and Broccoli
Sharp Knife, Clean Cuts
-
- A razor-sharp blade is your best friend. Thin, even slices cook faster and stay tender.
Don’t Crowd the Pan
-
- Work in batches so the beef and broccoli sear rather than steam. High heat is key to developing that signature wok hei “breath of the wok.”
Xanthan Gum Mastery
-
- Add xanthan gum gradually to cold liquid and whisk vigorously. Never dump it directly into hot sauce, or you’ll get clumps.
Timing Is Everything
-
- Prep every ingredient in advance (mise en place). Once you start stir-frying, things move at lightning speed.
Customize Your Crunch
-
- If you prefer an extra-crisp bite, skip blanching and flash-fry broccoli right in the wok—but watch closely to prevent burning.
Frequently Asked Questions
Can I use soy sauce instead of coconut aminos?
You can, but traditional soy sauce has about 1 g net carb per teaspoon. Coconut aminos contain less sugar overall and add a hint of sweetness without unwanted carbs.
What cut of beef is best?
Flank steak, flat-iron, or skirt steak are ideal—lean, flavorful, and sliceable. If you choose a fattier cut like ribeye, trim excess fat or expect a richer finish.
How do I store and reheat leftovers?
Keep in an airtight container in the fridge for up to 4 days. Reheat gently in a skillet over medium heat; add a splash of water or broth to refresh the sauce.
Is xanthan gum safe on keto?
Yes—xanthan gum is a zero-net-carb thickener derived from fermenting corn or soy and is generally well tolerated in small amounts.
Can I freeze this dish?
I don’t recommend it. The broccoli tends to become watery upon thawing and reheating. If you must, freeze the beef and sauce only, and add fresh or freshly blanched broccoli when reheating.
Conclusion
There you have it: Keto Low Carb Beef and Broccoli—a weeknight hero that checks all the boxes for flavor, speed, and macro-friendliness.
By swapping in coconut aminos, ditching starchy thickeners, and using chef-approved techniques, you’ll enjoy a stir-fry that rivals your favorite take-out joint, without the carb crash.
