Its a testament to resourcefulness and a desire to nourish loved ones, even when time is short.

The combination of savory sausage, fluffy eggs, melted cheese, and crusty bread creates a symphony of textures and flavors that's simply irresistible. It's the perfect balance of comfort food and morning fuel, guaranteed to kickstart your day on a high note. Plus, it's endlessly customizable!

Ingredients:
- 1 pound breakfast sausage, cooked and crumbled
- 1 green bell pepper, diced
- 1/2 red onion, diced
- 1 (10 ounce) package frozen chopped spinach, thawed and squeezed dry
- 12 large eggs
- 1 1/2 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder
- 1/4 teaspoon onion powder
- 6 slices bread, cubed (about 4 cups)
- 2 cups shredded cheddar cheese
- Optional: Hot sauce, to taste
Preparing the Sausage and Vegetables:
- First, let's get the sausage cooked. In a large skillet over medium heat, brown the breakfast sausage, breaking it up with a spoon as it cooks. Make sure it's cooked through no pink should remain. Once it's done, drain off any excess grease. I usually use a paper towel to soak up the extra grease.
- Now, add the diced green bell pepper and red onion to the skillet with the cooked sausage. Cook until the vegetables are softened, about 5-7 minutes. Stir occasionally to prevent burning. We want them to be tender and slightly translucent.
- Next, it's spinach time! Make sure your frozen spinach is completely thawed. The most important part is to squeeze out as much excess water as possible. I usually do this by placing the thawed spinach in a clean kitchen towel or cheesecloth and squeezing until almost no water comes out. This step is crucial to prevent the casserole from becoming soggy. Add the squeezed spinach to the skillet with the sausage and vegetables. Stir to combine everything well.
- Remove the skillet from the heat and set it aside to cool slightly. This will prevent the hot mixture from cooking the eggs prematurely in the next step.
Preparing the Egg Mixture:
- In a large bowl, crack all 12 eggs. Whisk them together until they are light and frothy. This usually takes about a minute or two.
- Add the milk, salt, pepper, garlic powder, and onion powder to the eggs. Whisk again until everything is well combined. Don't be afraid to really whisk it you want a homogenous mixture.
- If you like a little kick, now's the time to add a few dashes of your favorite hot sauce to the egg mixture. I personally love a little bit of heat in my breakfast casserole!
Assembling the Casserole:
- Grease a 9x13 inch baking dish. I usually use cooking spray, but you can also use butter or oil. Make sure to coat the entire dish, including the corners, to prevent sticking.
- Spread the cubed bread evenly in the bottom of the prepared baking dish. Try to distribute the bread cubes in a single layer.
- Pour the sausage and vegetable mixture evenly over the bread cubes. Make sure it's spread out so that every piece of bread gets some of the delicious sausage and veggies.
- Pour the egg mixture over the sausage, vegetables, and bread. Gently press down on the bread cubes with a spoon or spatula to ensure they are submerged in the egg mixture. This will help them soak up the egg and prevent them from drying out during baking.
- Sprinkle the shredded cheddar cheese evenly over the top of the casserole. Don't be shy with the cheese it adds a wonderful flavor and texture.
Refrigerating (Make-Ahead Option):
- If you're making this casserole ahead of time, cover the baking dish tightly with plastic wrap and refrigerate it for at least 2 hours, or preferably overnight. This allows the bread to fully absorb the egg mixture, resulting in a richer and more flavorful casserole.
- If you're baking it immediately, you can skip this step and preheat your oven.
Baking the Casserole:
- Preheat your oven to 350°F (175°C).
- If the casserole has been refrigerated, remove it from the refrigerator about 30 minutes before baking to allow it to come to room temperature slightly. This will help it bake more evenly.
- Uncover the baking dish and bake in the preheated oven for 45-55 minutes, or until the casserole is golden brown and the eggs are set. A knife inserted into the center should come out clean.
- If the top of the casserole starts to brown too quickly, you can loosely cover it with aluminum foil during the last 15-20 minutes of baking.
- Once the casserole is done, remove it from the oven and let it cool for about 10-15 minutes before slicing and serving. This allows the casserole to set up a bit, making it easier to cut and serve.
Serving Suggestions:
This make-ahead breakfast casserole is delicious on its own, but you can also serve it with a variety of toppings and sides. Here are a few ideas:
- Salsa: A dollop of salsa adds a fresh and zesty flavor.
- Sour Cream: A spoonful of sour cream adds a creamy and tangy element.
- Avocado: Sliced avocado adds a healthy and creamy texture.
- Hot Sauce: For those who like a little extra heat, a drizzle of hot sauce is perfect.
- Fresh Fruit: Serve with a side of fresh fruit, such as berries or melon, for a balanced breakfast.
- Toast or English Muffins: Add some extra carbs with toast or English muffins.
Tips and Variations:
- Cheese Variations: Feel free to experiment with different types of cheese. Monterey Jack, pepper jack, or Gruyere would all be delicious.
- Meat Variations: If you're not a fan of breakfast sausage, you can use bacon, ham, or even chorizo.
- Vegetable Variations: Add other vegetables, such as mushrooms, onions, or tomatoes.
- Bread Variations: Use different types of bread, such as croissants or sourdough.
- Dairy-Free Option: Use almond milk or soy milk instead of regular milk. You can also use a dairy-free cheese alternative.
- Gluten-Free Option: Use gluten-free bread.
- Spice it up: Add a pinch of red pepper flakes to the egg mixture for a little extra heat.
- Make it vegetarian: Omit the sausage and add more vegetables, such as mushrooms, zucchini, and bell peppers.
- Don't overbake: Overbaking can result in a dry casserole. Keep an eye on it and remove it from the oven as soon as the eggs are set.
- Cooling is key: Letting the casserole cool slightly before cutting helps it hold its shape and prevents it from falling apart.
Storage Instructions:
Leftover breakfast casserole can be stored in the refrigerator for up to 3-4 days. To reheat, simply microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through.
