Ingredients

6 English muffins, cubed
4 cups fresh spinach, roughly chopped
1 cup crumbled feta cheese
8 large eggs
2 cups milk (whole or plant-based)
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon garlic powder
1 tablespoon olive oil
Optional: 1/2 cup shredded mozzarella for extra cheesiness

Optional Additions and Substitutions

Swap feta for goat cheese or cheddar for a different flavor profile.
Add cooked and crumbled bacon, sausage, or diced ham for a protein boost.
Include sautéed mushrooms, bell peppers, or sun-dried tomatoes for extra veggies.
Use gluten-free English muffins for a gluten-free option.

Directions

Preheat the Oven: Set your oven to 350°F (175°C) and grease a 9×13-inch baking dish generously.
Cook the Spinach: Warm olive oil in a large skillet over medium heat, preparing it for the spinach to sauté evenly. Add the spinach and sauté until wilted, about 2-3 minutes. Remove from heat and let cool slightly.
Layer the Ingredients: Spread the cubed English muffins evenly in the prepared baking dish. Top with sautéed spinach and crumbled feta cheese.
Whisk the Egg Mixture: In a large bowl, whisk together eggs, milk, salt, pepper, and garlic powder until fully combined.
Assemble the Casserole: Pour the egg mixture evenly over the layers in the dish, ensuring everything is well coated. Gently press down with a spatula to submerge the bread.
Bake: Securely cover the baking dish with aluminum foil, ensuring a snug fit, and place it in the oven to bake for 25 minutes, allowing the ingredients to cook evenly while retaining their moisture. Remove the foil, sprinkle with shredded mozzarella (if using), and bake for an additional 15-20 minutes, or until the top is golden and the center is set.
Cool and Serve: Let the casserole cool for 5-10 minutes before slicing and serving.
