🥡 STORAGE: Store leftovers in an airtight container in the refrigerator for up to 4 days.

Keep rice or noodles stored separately if possible.

♨️ REHEATING: Reheat in the microwave in 30-second intervals until heated through.

Warm gently in a skillet over medium heat until hot.

Heat in a saucepan on the stovetop over medium-low heat, stirring occasionally.

❄️ FREEZING: Freeze without rice or noodles for up to 2 months.

Thaw overnight in the refrigerator, then reheat.

💡 TIPS FOR BEST RESULTS: Slice the beef thinly against the grain for tenderness.

Do not add the broccoli too early to prevent overcooking.

Taste before serving and adjust salt if needed.

🍳 ALTERNATE COOKING METHODS: Cook on high for 3-4 hours instead of low.

Simmer on the stovetop for 45-60 minutes until beef is tender, then add broccoli for the final 5-7 minutes.

Prepare in an Instant Pot on high pressure for 20 minutes, then perform a 10-minute natural release, then add broccoli on sauté mode for 3-5 minutes.

♻️ LEFTOVERS: Use in lettuce wraps for a quick lunch.

Spoon into tortillas for Asian-style tacos.

Serve over cauliflower rice for a low-carb option.

📝 NOTES: Cooking times may vary depending on your slow cooker.

For extra heat, add red pepper flakes or sliced chili peppers.

This recipe works well for meal prep.

For a thicker sauce, use a full tablespoon of cornstarch in the slurry.

For a thinner sauce, reduce the cornstarch slightly.
