About This Recipe

Recreating a stir-fry at home is a great way to enjoy familiar flavors while staying in control of the ingredients. This version focuses on the classic combination of beef and broccoli, using a savory sauce that swaps out traditional thickeners and sugars for keto-friendly alternatives. The result is a meal that provides a hearty protein base and fresh vegetables in a format that is much lighter and fresher than typical restaurant versions.

The appeal of this dish lies in its simplicity and how well the ingredients work together. The savory sauce coats the beef and broccoli evenly, providing a deep flavor that makes the meal feel indulgent. It’s a practical, straightforward dinner that fits easily into a busy weeknight routine, offering a reliable way to enjoy a warm, home-cooked meal that doesn’t require hours in the kitchen.

To get the best texture, slice your beef thinly against the grain; this ensures the meat stays tender and cooks quickly over high heat. Using a very hot skillet or wok is essential for getting a good sear on the beef without overcooking it. If you prefer a thicker sauce, a small pinch of xanthan gum can be whisked in at the end, but be sure to add it sparingly to avoid a gummy consistency. For the best crunch, stir-fry the broccoli just until it turns a vibrant green, keeping it “tender-crisp” so it holds its structure alongside the meat.
