Low-Carb Beef and Broccoli Ingredients
For the Marinade
- Soy Sauce or Coconut Aminos – Provides salty umami flavor; substitute coconut aminos for a gluten-free option.
- Beef Broth – Adds depth and richness to the sauce.
- Water – Balances the sauce’s consistency for the perfect texture.
- Fish Sauce – Enhances authenticity with a savory depth; avoid omission for best flavor.
- Garlic Powder – Offers aromatic flavor that complements the beef beautifully.
- Green Onions – Adds a fresh crunch and vibrant color.
- Granulated Sugar Substitute – Sweetens the dish without adding carbohydrates.
- Ground Ginger – Imparts warmth and spice, elevating the overall taste.
For the Main Dish
- Flank Steak – Main protein source, thinly sliced for quick cooking and tender results.
- Broccoli – Added for nutrients and a pop of color; use fresh for the best texture.
- Arrowroot Powder – Acts as a thickener for the sauce; can substitute with xanthan gum in lesser amounts.
Step‑by‑Step Instructions for Low-Carb Beef And Broccoli
Step 1: Prepare the Marinade
In a large measuring cup, whisk together soy sauce (or coconut aminos), beef broth, water, fish sauce, garlic powder, sliced green onions, sugar substitute, and ground ginger until fully combined. This fragrant marinade not only infuses the meat with umami flavor but also achieves the perfect balance of salty and sweet. Set aside for a moment while you prepare the flank steak.
Step 2: Marinate the Flank Steak
Place the thinly sliced flank steak into a resealable bag and pour the marinade over it, ensuring all pieces are well-coated. Seal the bag tightly and refrigerate for at least 30 minutes up to 4 hours. The longer it marinates, the more tender and flavorful the beef will be. While it marinates, preheat your Instant Pot to prepare for cooking.
Step 3: Prepare the Instant Pot
Once the marinade time is up, spray or oil the inner pot of your Instant Pot to prevent sticking. Add the marinated flank steak along with all the marinade to the pot. This step is crucial as it allows the beef to absorb all the flavorful juices during cooking. Ensure the meat is distributed evenly across the bottom for consistent cooking.
Step 4: Cook the Beef
Seal the Instant Pot lid, making sure the vent is set to ‘sealing,’ then set the pot to cook on high pressure for 10 minutes. During this time, the beef will become tender and infused with the delicious marinade flavors. After the timer goes off, allow the pressure to naturally release for a few minutes before moving to the next step.
Step 5: Steam the Broccoli
While the beef is cooking, prepare a steamer basket or microwave-safe bowl with fresh broccoli florets. Steam the broccoli until it’s crisp-tender, about 3-5 minutes, ensuring it retains its vibrant green color and crunch. As soon as the broccoli is done, remove it and set it aside; this will lighten up the overall dish.
Step 6: Release Pressure and Remove Beef
Carefully perform a quick release on the Instant Pot by moving the vent to ‘venting.’ Once all the steam escapes, remove the lid and take out the beef with tongs; set it aside to keep warm. You’ll notice a beautifully rich sauce remaining in the pot, ready to be thickened for your luscious Low-Carb Beef And Broccoli.
Step 7: Thicken the Sauce
Cancel the cooking mode and select ‘sauté’ on the Instant Pot. In a small bowl, whisk together arrowroot powder with a few tablespoons of water to create a slurry. Pour this mixture into the boiling sauce and stir continuously until it thickens to your desired consistency, around 2-3 minutes. Once thickened, the sauce will cling beautifully to the beef and broccoli.
Step 8: Combine and Heat Through
Return the cooked beef and steamed broccoli to the pot, gently tossing them in the rich sauce until everything is well-coated and heated through. This final step ensures that each bite of your Low-Carb Beef And Broccoli is packed with flavor and perfectly juicy. Serve hot and enjoy the savory goodness you’ve created!

Low-Carb Beef and Broccoli Recipe FAQs
What type of soy sauce or coconut aminos should I use?
I recommend using low-sodium soy sauce or coconut aminos if you’re looking for a gluten-free option. Coconut aminos has a slightly sweeter and milder flavor than soy sauce, making it a great substitute without compromising on taste!

Absolutely! You can freeze it in an airtight container or a heavy-duty freezer bag for up to 3 months. Be sure to label the container with the date to easily keep track of it. For best results, avoid freezing the broccoli separately, as it may lose its texture when thawed.
What should I do if my sauce is too thin?
If your sauce turns out too thin after thickening, you can create a quick arrowroot slurry. Mix 1 tablespoon of arrowroot powder with 2 tablespoons of cold water in a small bowl. Gradually whisk this mixture into the simmering sauce, stirring continuously until it thickens to your desired consistency. This will give your dish that glossy finish!
Is Low-Carb Beef and Broccoli safe for my pet?
While ingredients like beef and broccoli are generally safe for pets in moderation, it’s best to avoid seasoning, particularly soy sauce or fish sauce, as they can be harmful to animals. Always consult your vet before sharing human food with your furry friends.

Be cautious with soy sauce and fish sauce, as people may have allergies or sensitivities to soy or seafood. For those with gluten intolerance, remember to use coconut aminos as a substitute for soy sauce to keep it gluten-free.
