Keto Beef and Broccoli

A standard beef and broccoli from a Chinese restaurant has 15 to 25g of carbs per serving, mostly from cornstarch and brown sugar in the sauce. I skip all of that. My version uses soy sauce, sesame oil, and a splash of apple cider vinegar for the same savory depth with zero thickeners and zero added sugar. The whole thing cooks in one skillet in 10 minutes.

Why I Use Ground Beef

Traditional stir fry calls for thinly sliced flank steak or sirloin. That works, but it adds real prep time. You need to partially freeze the steak, slice it thin against the grain, then sear in small batches so it doesn’t steam. Ground beef skips all of that. Brown it, break it into pieces, and you’re building the sauce in under 5 minutes. I always have ground beef in the fridge or freezer, which makes this my default dinner when I haven’t planned anything. If you like ground beef one-pan meals, my hamburger helper uses the same pantry-ready approach.

The Sauce

Three ingredients: soy sauce, sesame oil, and apple cider vinegar. The soy provides the salty umami base. The sesame oil adds richness and that Chinese restaurant flavor. The vinegar cuts through the fat so it doesn’t feel heavy. No cornstarch, no oyster sauce, no sugar. If you want a thicker sauce, let it reduce for an extra 30 seconds before adding the broccoli.

I’ve tested this with fresh ginger and without. Most recipes online include it, and it does add warmth, but I prefer the version without because the sesame oil flavor comes through cleaner. If you want that ginger note, grate about a teaspoon into the skillet with the garlic.

This is the same flavor approach I use in my teriyaki chicken and hunan chicken. Once you’re comfortable building Asian flavors from soy sauce and sesame oil, you can adapt the ratios for almost anything. My cashew beef is the same idea with a different finish.

One Skillet, Start to Finish

Everything cooks in one 12-inch skillet. Brown the beef, add the sauce, toss in the broccoli, cover, and let it steam for 3 to 5 minutes. I start checking at 4 minutes because the broccoli keeps cooking in the hot pan after you pull the lid off. You want a little bite left. When it’s fork-tender, dinner is done. One pan to wash.

1. Brown the ground beef. Heat avocado oil in a 12-inch skillet over medium-high. Add ground beef, break into small pieces, and cook until browned with slightly crispy edges (about 4 to 5 minutes). Stir in garlic and onion powder for 30 seconds.
2. Build the sauce. Pour in soy sauce, sesame oil, and apple cider vinegar. Stir to coat the beef evenly. Let it simmer for 30 seconds so the flavors concentrate.
3. Steam the broccoli. Add broccoli florets, stir once, then cover the skillet. Let steam over medium heat for 3 to 5 minutes until the broccoli is fork-tender but still has some bite.

Key ingredients

• Ground beef. I use ground beef because it browns in 5 minutes without any slicing or prep. Any fat percentage works. You can also use beef strips, chopped leftover steak, or beef tips.
• Garlic. Two cloves minced, or substitute 1 teaspoon garlic powder. Skip garlic salt since the soy sauce already provides plenty of sodium.
• Soy sauce. The salty, umami backbone of the sauce. For gluten-free, use tamari. For soy-free, use liquid aminos or coconut aminos (coconut aminos is slightly sweeter, so use the same amount).
• Sesame oil. This is what gives the dish its Chinese restaurant flavor. Regular sesame oil has a milder taste. Toasted sesame oil is more concentrated, so if using toasted, start with 2 tablespoons and adjust.
• Apple cider vinegar. A small amount of acid balances the richness of the sesame oil and beef fat. White vinegar or rice vinegar work as substitutes.
• Broccoli florets. I use the pre-cut fresh florets from a bag to skip the prep. Frozen broccoli works too, but add 1 to 2 extra minutes of steaming time since it releases more water.
