For best results, make sure the spinach is thoroughly squeezed dry to avoid a watery dip, and soften the cream cheese to room temperature so it blends smoothly without lumps. If you like a browner top, switch the oven to broil for the last 1–2 minutes, watching closely to prevent burning. You can prepare the mixture up to a day ahead, cover and refrigerate it, then add a few extra minutes to the baking time when cooking from cold. Adjust richness by swapping some mayonnaise for extra sour cream, and feel free to customize with additions like chopped jalapeños, extra garlic, or a handful of shredded mozzarella on top for an extra-cheesy finish.
