Chef's tips: Pat the shrimp very dry to get a golden sear; never crowd the pan. Add the garlic only after the broccoli is done, because it burns in seconds. The sauce will continue to thicken as it cools slightly. Leftovers keep in the fridge for up to 3 days in an airtight container; the finished dish does not freeze well, but the sauce alone freezes for up to 3 months. For dairy-free, use a good vegan butter. For gluten-free, swap the soy sauce for tamari or coconut aminos.
