Instructions

1. 1

   Preheat your oven to ![350°F]. Place the thawed frozen spinach in a clean kitchen towel or several layers of paper towels and squeeze out as much liquid as possible — this step is critical. You want the spinach as dry as you can get it so the dip isn't watery.

2. 2

   Melt the butter in a small skillet over ^[medium heat]. Add the diced yellow onion and cook, stirring occasionally, for 4–5 minutes until softened and translucent. Add the minced garlic and cook for another 60 seconds until fragrant. Remove from heat and set aside to cool slightly.

3. 3

   In a large mixing bowl, beat the softened cream cheese with a hand mixer (or a sturdy spatula) until smooth and lump-free, about 1–2 minutes. This ensures a creamy, uniform dip.

4. 4

   Add the sour cream, mayonnaise, lemon juice, onion powder, garlic powder, kosher salt, black pepper, and red pepper flakes (if using) to the cream cheese. Mix until fully combined and smooth.

5. 5

   Fold in the sautéed yellow onion and garlic, the squeezed-dry spinach, ¾ cup of the shredded mozzarella, and all of the Parmesan cheese. Stir until everything is evenly distributed. Taste and adjust kosher salt and black pepper as needed.

6. 6

   Transfer the mixture to a 1-quart baking dish (or a hollowed-out sourdough bread boule set on a baking sheet). Spread it into an even layer and sprinkle the remaining ¼ cup of mozzarella cheese over the top.

7. 7

   Bake at ![350°F] for 20–25 minutes, until the dip is hot and bubbling around the edges and the cheese on top is melted and lightly golden. For extra color, broil for the last 1–2 minutes.

8. 8

   Remove from the oven and let rest for 5 minutes before serving. Serve warm with crackers, pita chips, sliced baguette, or fresh vegetables like celery, carrots, and bell pepper strips.
