Ingredients

2 (10 oz) packages frozen spinach, thawed and squeezed
1 cup all-purpose flour
1 tsp salt
1 tsp baking powder
1 tsp red pepper flakes
2 tsp dried oregano
2 eggs
1 cup 2% milk
¼ cup butter, melted
1 sweet onion, chopped
1 garlic clove, minced
1 (8 oz) package shredded mozzarella cheese

Instructions

Step 1: Preheat your oven to 375°F. Grease and flour a 9×13-inch baking dish to prevent sticking.
Step 2: In a large bowl, combine the flour, salt, baking powder, red pepper flakes, and dried oregano. Mix well.
Step 3: Add the eggs, milk, melted butter, chopped onion, minced garlic, squeezed spinach, and shredded mozzarella cheese to the dry ingredients. Stir until everything is well incorporated.
Step 4: Pour the mixture into the prepared baking dish, spreading it evenly. Bake for 30 to 35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

Tips & Variations

For a spicier kick, increase the red pepper flakes or add a pinch of cayenne pepper.
Try substituting mozzarella with feta or cheddar cheese for different flavors.
Fold in some chopped sun-dried tomatoes or olives for extra texture and taste.
Make sure to squeeze out excess water from the spinach to avoid a soggy bake.

Storage

Store leftover spinach brownies in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through. For longer storage, freeze the brownies wrapped tightly and thaw before reheating.

How to Serve

A baked dish in a white rectangular pan shows a thick layer of green spinach mixed with a creamy, pale yellow base that looks soft and moist inside, topped with golden brown, slightly crispy spots unevenly spread over the surface. There is a square piece cut out revealing the inside texture which is dense with visible green leafy bits and a smooth, cheesy consistency. A butter knife with some residue rests on the pan near the cut section. The pan sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use fresh spinach instead of frozen?

Yes, you can substitute fresh spinach. Use about 10-12 cups of fresh spinach, sauté it until wilted, then squeeze out excess moisture before adding to the batter.

Are these brownies gluten-free?

This recipe uses all-purpose flour, which contains gluten. You can substitute with a gluten-free flour blend to make it gluten-free, but texture may vary slightly.
