Cook the thick-cut bacon in a large skillet until very crisp. Transfer to a paper towel-lined plate and let cool completely to solidify the fat. Once cooled, crumble into small pieces for even distribution.

Cook frozen chopped spinach according to package instructions. Once cooked, press out all excess moisture using paper towels or a clean kitchen cloth to prevent sogginess.

In a large mixing bowl, whisk together the all-purpose flour, baking powder, kosher salt, dried oregano, dried thyme, and black pepper until evenly combined to ensure even flavor.

In a separate bowl, combine the milk, lemon juice, and eggs, whisking to blend. Add the cooked spinach, crumbled bacon, cheddar cheese (reserve ½ cup), pepper jack cheese, diced onion, and minced garlic. Gradually fold this mixture into the dry ingredients using a sturdy spoon until no flour streaks remain.

Spray a baking pan generously with nonstick spray. Transfer the spinach mixture into the pan, pressing gently to fill corners evenly. Smooth the top with a spatula and sprinkle the reserved ½ cup cheddar cheese evenly over the surface for a golden crust.

Bake in a preheated oven at 375°F for 45 to 50 minutes, until the top is deep golden brown and the center is fully set. The edges should slightly pull away from the pan.

Allow the bake to cool for at least 15 minutes to firm up for clean slicing. Use a sharp knife to cut into squares and serve warm or at room temperature.
