Ingredients for Spinach and Sausage Egg Casserole

• Breakfast Sausage: Adds a savory, meaty flavor and richness. The fat content also helps to keep the casserole moist and infuses the eggs and vegetables with flavor. (1 lb)
• Eggs: Form the main binder and base of the casserole. As they bake, they set and hold everything together, providing protein and structure. (11 large)
• Skim Milk: Lightens the egg mixture, resulting in a more custardy and less dense texture. It also helps to distribute flavors evenly throughout the dish. (1/2 cup)
• Salt and Black Pepper: Essential seasonings to enhance all the other flavors. Salt balances richness, and pepper adds a gentle warmth. (1/2 teaspoon salt)
• Sharp Cheddar Cheese: Provides a bold, tangy flavor and creamy texture. Sharp cheddar stands out against the eggs and sausage, adding depth to the casserole. (2 cups shredded)
• Dried Oregano: Brings a warm, earthy, and slightly peppery note that complements both the sausage and cheese, layering in herbal flavor. (1 teaspoon)
• Fresh Spinach: Adds color, nutrients, and a fresh contrast to the richness of the meat and cheese. It also introduces a bit of moisture and balance. (2 cups chopped)

How to Make Spinach and Sausage Egg Casserole

1. Prep: Preheat the oven to 350℉ (175°C) and grease a 9×13 inch casserole dish.
2. Cook the Sausage: Heat a skillet over medium-high heat and cook the sausage, breaking it apart as it cooks. Drain off any excess grease and set the cooked sausage aside.
3. Combine: In a large bowl, whisk together the eggs and milk. Season with salt and pepper. Add the cooked sausage, cheddar cheese, dried oregano, and fresh spinach to the bowl. Stir well to combine all ingredients.
4. Bake: Pour the egg mixture into the prepared casserole dish. Bake for 30-40 minutes, or until the casserole is set and a knife inserted into the center comes out clean.

Is Egg Casserole a Healthy Breakfast Option?

The nutritional value of egg casseroles depends on the ingredients used. This particular recipe is designed to be a healthier option, being low in carbohydrates (approximately 2g per serving) and high in protein (around 16g per serving). A full serving contains only about 250 calories, making it a hearty and satisfying breakfast that won’t weigh you down. Choosing lean sausage, using skim milk, and loading up on spinach contribute to its overall healthfulness.

What to Serve with Spinach and Sausage Egg Casserole

This versatile casserole can be enjoyed on its own or paired with various side dishes to create a complete and flavorful meal. For a fresh and zesty contrast, I love to serve it with a scoop of homemade pico de gallo. Alternatively, it would be fantastic with some salsa verde or restaurant-style salsa.

If you enjoy a combination of sweet and savory for breakfast, I highly recommend serving this casserole alongside a batch of bakery-style blueberry muffins! The sweet muffins complement the savory casserole perfectly.

Can I Prepare Spinach and Sausage Egg Casserole in Advance?

Absolutely! This is a fantastic make-ahead recipe. Simply follow the instructions as written, assemble the casserole, and then store it in the refrigerator until you’re ready to bake it. You can prepare it up to 24 hours in advance. When you’re ready to bake, simply follow the baking instructions.

Preparing this casserole ahead of time is especially convenient for busy mornings, holiday gatherings, or when you want to enjoy a stress-free weekend brunch.

Storing, Freezing, and Reheating Your Egg Casserole

Proper storage and reheating techniques will help maintain the flavor and texture of your spinach and sausage egg casserole.

• Storing: Leftover casserole should be stored in an airtight container in the refrigerator. It will keep for 4-5 days.
• Freezing: Egg casseroles freeze exceptionally well. After baking, allow the casserole to cool completely. Then, wrap it tightly in plastic wrap, followed by a layer of aluminum foil. It can be stored in the freezer for up to 3 months.
• Reheating: For a single serving, microwaving is a quick and convenient option. To reheat a larger portion of the casserole, the oven is preferable. Place the casserole in an oven preheated to 350 degrees F (175°C) and heat it through for approximately 15 minutes.

To reheat a frozen casserole, allow it to thaw overnight in the refrigerator before reheating it in the oven as described above.
