Ingredients

1 lb flat iron steak, thinly sliced against the grain
1/2 lb broccoli, cut into small florets
1/4 cup coconut oil
1 teaspoon toasted sesame oil
1 teaspoon fish sauce

Beef and Broccoli Marinade

1/4 cup coconut aminos
1 teaspoon fresh ginger, peeled and grated
2 garlic cloves, chopped

Instructions

Slice the flat iron steak very thinly against the grain.
Place the sliced beef in a resealable bag or covered bowl. Add the coconut aminos, grated fresh ginger, and chopped garlic. Mix until the beef is evenly coated.
Refrigerate and allow the beef to marinate for 1 hour.
When ready to cook, remove the beef from the marinade and reserve the marinade to use as the stir-fry sauce.
Bring a pot of water to a boil. Add the broccoli and blanch for 2 minutes. Drain thoroughly.
Heat the coconut oil in a large wok or cast-iron skillet over medium-high heat.
Add the drained beef and stir-fry for 1–3 minutes, or until nicely browned. Work in batches if necessary to avoid overcrowding the pan. Remove the beef and set aside.
Add the broccoli to the hot pan and stir-fry for about 3 minutes, until crisp-tender.
Pour the reserved marinade into the skillet and cook with the broccoli for about 2 minutes, making sure the sauce comes to a full simmer.
Return the cooked beef to the skillet and toss everything together until hot and evenly coated.
Stir in the fish sauce and toasted sesame oil. Serve your Keto Beef and Broccoli immediately while the beef is tender and the broccoli is still crisp.

Tips & Tricks

Slice the steak against the grain as thinly as possible. This shortens the muscle fibers and helps produce more tender bites of beef.

For easier slicing, place the steak in the freezer for about 20–30 minutes before cutting. It should become firm but not frozen solid.

Fresh ginger is preferable to powdered ginger because it gives this healthy beef and broccoli recipe a brighter, fresher flavor.

Drain the blanched broccoli thoroughly before adding it to the skillet. Excess water can dilute the sauce and prevent the vegetables from stir-frying properly.

A very hot pan helps brown the beef rather than steam it. If your skillet is small, cook the meat in two batches.

Choose halal-certified beef and fish sauce when required. Check the labels of packaged condiments to ensure they meet your dietary requirements.

Notes

Flat iron steak works particularly well because it cooks quickly and stays tender when thinly sliced. Flank steak or sirloin can also be used.

If you prefer a milder flavor, reduce the fish sauce slightly. For extra sesame flavor, sprinkle toasted sesame seeds over the finished dish.

Serve this low carb Chinese-inspired recipe with cauliflower rice, sautéed cabbage, zucchini noodles, or additional steamed vegetables.

For extra heat, add a small amount of crushed red pepper flakes or sliced fresh chili.

FAQ

Traditional versions can contain sugar, cornstarch, and sauces with added carbohydrates. This Keto Beef and Broccoli uses coconut aminos and skips sugary thickeners, making it more suitable for a low carb eating plan.

What is the best beef for keto beef and broccoli?

Flat iron steak is an excellent choice because it is flavorful and tender when sliced thinly against the grain. Flank steak and sirloin are good alternatives.

Can I make keto beef stir fry without coconut aminos?

Yes. You can substitute a low-sugar soy sauce or tamari if it fits your dietary preferences. Keep in mind that the flavor and carbohydrate content may change.

Why should I slice beef against the grain?

Cutting against the grain shortens the meat fibers, making each bite easier to chew and more tender.

Can I serve this with cauliflower rice?

Can I add more vegetables?

Yes. Low carb vegetables such as mushrooms, zucchini, bell peppers, bok choy, or cabbage can be added. Keep the total carbohydrate content of your chosen vegetables in mind if you follow strict keto macros.

Storage

Allow leftovers to cool before transferring them to an airtight container. Refrigerate for up to 3–4 days.

For freezing, place cooled portions in freezer-safe containers and freeze for up to 2 months. The beef freezes well, although the broccoli may become softer after thawing.
