Ingredients
Beef and Broccoli
- 1 lb flat iron steak, thinly sliced against the grain
- 1/2 lb broccoli, cut into small florets
- 1/4 cup coconut oil
- 1 tsp toasted sesame oil
- 1 tsp fish sauce
Beef and Broccoli Marinade
- 1/4 cup coconut aminos
- 1 tsp fresh ginger, peeled and grated
- 2 cloves garlic, chopped
Instructions
- Thinly slice the flat iron steak against the grain. Thin slices help the beef cook quickly and stay tender.
- Place the sliced beef in a small food-safe bag or container. Add the coconut aminos, grated fresh ginger, and chopped garlic. Seal and refrigerate for 1 hour.
- When ready to cook, drain the beef and reserve the marinade. The reserved liquid will become the stir-fry sauce.
- Bring a pot of water to a boil. Add the broccoli and blanch for 2 minutes. Drain thoroughly so excess water does not interfere with stir-frying.
- Heat the coconut oil in a large wok or cast-iron skillet over medium-high heat.
- Add the marinated beef and stir-fry for about 1–3 minutes, or until browned and cooked to your preferred doneness. Transfer the beef to a plate.
- Add the broccoli to the hot skillet and stir-fry for about 3 minutes, until crisp-tender.
- Pour the reserved marinade into the skillet and cook for about 2 minutes. For food safety, make sure the marinade reaches a thorough simmer while cooking.
- Return the beef to the skillet and toss with the broccoli until everything is hot and evenly coated.
- Add the fish sauce and toasted sesame oil. Toss briefly, then serve the keto beef and broccoli hot.
Tips & Tricks
- Slice against the grain: Look for the direction of the muscle fibers and slice across them. This helps produce more tender bites.
- Use fresh ginger: Freshly grated ginger gives the marinade a brighter flavor than powdered ginger.
- Do not overcrowd the pan: Cook in batches if necessary. Too much beef at once can cause it to steam instead of brown.
- Drain the broccoli well: Excess water can lower the temperature of the skillet and prevent good browning.
- Keep the broccoli crisp-tender: A short blanch followed by stir-frying gives it a tender center with a pleasant bite.
- Watch the sauce: Coconut aminos can vary in sweetness and saltiness between brands, so taste the finished sauce before adding additional seasoning.
- Oil swap: Avocado oil or another suitable high-heat cooking oil can be used in place of coconut oil if preferred.
- Protein swap: Thinly sliced sirloin or another tender beef cut can work in place of flat iron steak.

Notes
For an especially quick dinner, slice the beef and prepare the broccoli while the beef marinates. Serve the finished stir-fry on its own for a very low-carb meal, or pair it with cauliflower rice for a more substantial keto dinner.
If you prefer a stronger ginger flavor, add a little extra freshly grated ginger to the marinade. For a milder flavor, reduce the fish sauce slightly.
Always check the labels of packaged ingredients such as coconut aminos and fish sauce to confirm that they meet your dietary requirements.
