There is something reliable about spinach dip that will lure people from all corners of the room to grab a chip and tuck into its cheesy, savory goodness. Ask yourself: Do you know anyone who doesn’t like spinach dip? I don’t.Here we have dropped the traditional mayo and are using a combination of Greek yogurt and reduced-fat cream cheese as the base. We’ve also used some mozzarella and Parmesan for that trademark cheesiness. The pinch of nutmeg might sound odd, but trust me. Nutmeg is used in classic steakhouse creamed spinach for its ability to provide a subtle warmth to the inherently savory dish. It is that little something that brings it all home.
Heat 1 tablespoon of the oil in a sauté pan over medium-low heat. Add the onion and cook, stirring occasionally, for 4 to 5 minutes until lightly browned. Add the garlic and ¼ teaspoon of the salt and cook an additional 3 to 4 minutes, or until the onions are light golden but not browned. Remove from the heat, place on a plate, and let cool to room temperature.
Pat the spinach as dry as you can and place it in the bowl of a food processor. Add the yogurt, cream cheese, ¼ cup of the mozzarella, the remaining 1 teaspoon of salt, the pepper, and the nutmeg. Process until smooth.
Add the onion mixture to the food processor and pulse just 2 or 3 times to combine. Coat a broiler-safe baking dish (8-inch square or 10 by 7 inches) with the remaining 1 tablespoon of olive oil.
Transfer the spinach dip into the dish and top with the remaining ¼ cup of mozzarella and the Parmesan. Bake for 15 to 20 minutes, or until the dip is heated through and bubbling.
Turn the broiler to high and broil for 3 to 4 minutes until the top is well browned. Serve with pita wedges and/or crudités.
Notes
If made ahead, refrigerate the dip for up to 24 hours and bake, covered, for 20 to 30 minutes at 350°F until warm and bubbling.
