Ingredients
- Thick cut bacon: brings smoky salty flavor Use a block-style bacon for bigger bites and less shrinkage
- Frozen chopped spinach: offers convenience and texture Squeeze it really dry for best results
- All purpose flour: creates structure Use a fresh bag for lighter baking
- Baking powder: helps the squares puff slightly Select an aluminum free variety for a clean taste
- Kosher salt: balances bold flavors Go for fine grain for even mixing
- Dried oregano and dried thyme: add layers of herb flavor Mediterranean blends work perfectly
- Black pepper: brings subtle heat Fresh cracked will be more aromatic
- Milk: keeps the mix moist Whole milk is ideal for richness
- Lemon juice: brightens and activates the baking powder Fresh squeezed makes a difference
- Large eggs: bind everything Use room temperature eggs for best incorporation
- Seriously Sharp Cheddar Cheese: delivers tangy depth Look for hand-shredded cheese from a block for meltability
- Pepper Jack Cheese: infuses an extra kick Pre-shredded works in a pinch but hand-shredded blends better
- Yellow onion: diced fine for gentle sweetness Choose a firm heavy onion for best flavor
- Minced garlic: wakes up all the flavors Fresh minced will outperform jarred every time
Step-by-Step Instructions
- Prep the Bacon:
- Begin by cooking the bacon in a large skillet until very crisp Set aside on a towel lined plate and let cool so the fat solidifies This makes it easier to crumble and mix throughout the batter for rich bites in every piece
- Prepare the Spinach:
- Cook the spinach straight from frozen following the package instructions When ready squeeze out every last bit of liquid using paper towels or a dishcloth Dry spinach is key or the squares will turn soggy
- Mix the Dry Ingredients:
- In a large mixing bowl combine flour baking powder salt oregano pepper and thyme Stir well so the leavening and seasoning are completely blended to prevent flavor pockets
- Combine Wet Ingredients and Bacon:
- Add milk lemon juice eggs two cups of cheddar cheese Pepper Jack cheese diced onions and minced garlic to the spinach and bacon mixture This is where the base comes together Use a sturdy spoon to work everything until no streaks of flour remain
- Assemble and Top:
- Spray your baking pan liberally with nonstick spray to avoid sticking Pour in the thick spinach mixture and press it gently into corners Even out the top with a spatula for uniform texture Sprinkle the last half cup of cheddar cheese all over so you get a bubbly golden crust
- Bake and Cool:
- Slide the pan into a preheated oven at three seventy five degrees and bake forty five to fifty minutes until deep golden and completely set The edges should pull slightly from the sides Cool at least fifteen minutes for clean cutting
- Slice and Serve:
- Use a sharp knife to portion the warm or room temperature bake into squares Serve piled on a platter or right from the pan for a rustic look
