Preheat your oven to 375°F (190°C). Slice the baguette into 1/2 inch slices and brush both sides with olive oil. Arrange the slices on a baking sheet.

Toast the Baguette

Bake the baguette slices in the preheated oven for about 10-12 minutes or until they are golden brown and crisp. Remove from the oven and set aside.

Cook the Spinach

In a large skillet, sauté the minced garlic in a little olive oil over medium heat for about 1 minute until fragrant. Add the chopped spinach and cook until wilted, about 3-4 minutes. Remove from heat.

Mix the Dip

In a mixing bowl, combine the cooked spinach, cream cheese, sour cream, mayonnaise, mozzarella cheese, Parmesan cheese, salt, and black pepper. Mix until well combined.

Bake the Dip

Transfer the spinach mixture to a baking dish and spread evenly. Bake in the oven at 375°F (190°C) for 20-25 minutes or until bubbly and golden on top.

Serve

Remove from the oven and serve warm with the toasted baguette slices.
