What You’ll Need

This recipe calls for simple, readily available ingredients, ensuring a smooth and stress-free cooking experience. Here’s what you’ll need to gather before we get started:

• Eggs: Large, fresh eggs form the base of this creamy casserole. Aim for a good quality brand.
• Milk: Whole milk adds richness and creaminess to the casserole. You can substitute with half-and-half or heavy cream for an even richer flavor.
• Sharp Cheddar Cheese: Provides a sharp, salty flavor that perfectly balances the spinach. Shredded cheddar is ideal, but you can grate your own.
• Spinach: Fresh spinach provides a delightful pop of color and a slightly earthy taste. Make sure to thoroughly wash and dry it before use.
• Onion: A small yellow onion adds subtle depth of flavor. Finely chopped, it blends beautifully into the casserole.
• Garlic: Fresh garlic cloves add that characteristic pungent aroma and flavor that elevates the dish.
• Salt and Pepper: These essential seasonings enhance the flavors of the other ingredients. Don’t be shy with the seasoning!
• Breadcrumbs: Adds a delightful crunch to the top of the casserole. Plain breadcrumbs work perfectly.
• Butter: Adds a richness to the casserole. Unsalted butter is preferred so you control the salt level.

Step-by-Step Instructions

Let’s create this delicious make-ahead egg casserole together! Follow these simple steps for a perfectly cooked and flavorful breakfast (or brunch, or dinner!).

1. Preheat and Prep: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter. This prevents sticking and ensures easy serving.
2. Sauté Aromatics: In a medium skillet, melt 1 tablespoon of butter over medium heat. Sauté the finely chopped onion and garlic until softened, about 3-5 minutes. Don’t brown them; just soften them to release their flavors.
3. Wilt the Spinach: Add the spinach to the skillet and cook until it wilts, about 2-3 minutes. Drain any excess liquid. Season with salt and pepper.
4. Whisk the Egg Mixture: In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined. A bit of black pepper really enhances the egg flavor.
5. Combine Ingredients: Gently fold in the sautéed onion, garlic, and spinach into the egg mixture. Then, stir in most of the shredded cheddar cheese, reserving some for topping.
6. Assemble the Casserole: Pour the egg mixture into the prepared baking dish. Sprinkle the reserved cheddar cheese evenly over the top. Then sprinkle the breadcrumbs evenly on top.
7. Bake: Bake for 45-50 minutes, or until the casserole is set and lightly golden brown on top. Use a toothpick inserted into the center to check; it should come out clean.
8. Cool and Serve: Allow the casserole to cool slightly before slicing and serving. This helps the casserole firm up and makes it easier to cut clean slices.

Pro Tip: For extra flavor, consider adding a pinch of nutmeg or paprika to the egg mixture.

Tips for Success

To ensure your spinach and cheese egg casserole turns out perfectly every time, here are some helpful tips to avoid common pitfalls:

Don’t overcook the spinach: Overcooked spinach can become watery and affect the casserole’s texture. Cook it just until wilted.

Don’t overbake the casserole: Overbaking can result in a dry casserole. Start checking for doneness around the 45-minute mark.

Use fresh ingredients: Fresh ingredients always yield the best flavor. Opt for fresh spinach, garlic, and high-quality cheese.

Grease the baking dish well: This will prevent the casserole from sticking and make it easier to serve.

Let it cool slightly before serving: This allows the casserole to set properly and makes for easier slicing.

Variations to Try

Make it spicy: Add a pinch of red pepper flakes or a dash of your favorite hot sauce to the egg mixture.

Make it vegetarian: This recipe is already vegetarian-friendly! Just ensure your cheese is vegetarian.

Storing and Reheating

This make-ahead casserole is perfect for meal prepping! To store leftovers, let the casserole cool completely. Then, cover it tightly with plastic wrap or aluminum foil and refrigerate for up to 3 days. To freeze, allow the casserole to cool completely, then wrap it tightly in plastic wrap, followed by aluminum foil or a freezer-safe bag. It can be frozen for up to 2 months. To reheat, thaw overnight in the refrigerator. Then, reheat in a preheated oven at 350°F (175°C) for 20-25 minutes, or until heated through. You can also microwave individual portions for 1-2 minutes, but the oven method maintains the best texture.
