Ingredients

• 8 large eggs
• 1 cup whole milk (240 ml)
• 1½ cups shredded cheddar cheese (150 g)
• 1 cup diced ham (150 g)
• ½ cup diced bell pepper (75 g)
• ¼ cup diced onion (40 g)
• 1 tablespoon butter (for greasing)
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ½ teaspoon garlic powder

Step-by-Step Instructions

1. Preheat the oven

Start by preheating your oven to 350°F (175°C). This temperature ensures the eggs cook evenly without becoming rubbery or dry.

While the oven heats up, gather all your ingredients and prep your baking dish. Use the tablespoon of butter to generously grease a 9×13 inch baking dish.

2. Prepare the vegetables

Dice your bell pepper and onion into small, uniform pieces. Keeping them roughly the same size ensures even cooking throughout the casserole.

You can use any color bell pepper you prefer – red and yellow add sweetness while green offers a more savory note. Set the diced vegetables aside once they’re ready.

3. Whisk the eggs

Crack all 8 eggs into a large mixing bowl. Add the milk, salt, black pepper, and garlic powder to the bowl.

Whisk everything together vigorously until the mixture is completely smooth and slightly frothy. This incorporates air into the eggs, which helps create that fluffy texture we’re looking for.

4. Add the fillings

Scatter the diced ham evenly across the bottom of your prepared baking dish. Add the diced bell pepper and onion on top of the ham.

Sprinkle about 1 cup of the shredded cheddar cheese over the meat and vegetables. Reserve the remaining ½ cup of cheese for topping.

5. Pour the egg mixture

Slowly pour the whisked egg mixture over the fillings in the baking dish. Use a fork or spatula to gently distribute everything evenly.

The liquid should come up around the fillings but not overflow. Give the dish a gentle shake to help settle everything into place.

6. Add the cheese topping

Sprinkle the remaining ½ cup of cheddar cheese evenly over the top of the casserole. This creates that beautiful golden, slightly crispy cheese layer we all love.

Make sure the cheese reaches the edges for maximum coverage and flavor in every bite.

7. Bake until golden

Place the casserole in your preheated oven and bake for 35-40 minutes. The casserole is done when the top is golden brown and the center is set.

To test doneness, insert a knife into the center – it should come out clean. The edges will be slightly puffed and pulling away from the sides of the dish.

8. Rest before serving

Remove the casserole from the oven and let it rest for 5 minutes before cutting. This resting period allows the eggs to set completely and makes slicing much easier.

The casserole will deflate slightly as it cools, which is completely normal. Cut into squares and serve warm.

Tips for Variations or Side Dishes

Vegetarian version: Skip the ham and add sautéed mushrooms, spinach, or sun-dried tomatoes instead. You’ll get plenty of flavor without the meat.

Mexican twist: Use pepper jack cheese, add diced jalapeños, and top with salsa and sour cream after baking. A sprinkle of fresh cilantro takes it over the top.

Mediterranean style: Swap cheddar for feta cheese and add chopped olives, sun-dried tomatoes, and fresh basil. Drizzle with olive oil before serving.

Low-carb option: This recipe is already low in carbohydrates, making it perfect for keto dieters. Simply ensure your add-ins don’t contain hidden sugars.

For side dishes, consider fresh fruit salad, crispy hash browns, or buttered toast. A simple green salad with vinaigrette also complements the richness of the casserole beautifully.

Serving Suggestions

Serve this egg casserole straight from the baking dish while it’s still warm and inviting. Cut it into generous squares and use a spatula to transfer portions to plates.

Garnish each serving with fresh chopped chives or parsley for a pop of color and freshness. A dollop of sour cream or a drizzle of hot sauce adds extra flavor for those who want it.

This casserole pairs wonderfully with a glass of fresh orange juice or a hot cup of coffee. For a more substantial meal, serve it alongside bacon strips or breakfast sausages.

If you’re hosting brunch, set up a topping bar with salsa, avocado slices, and various hot sauces. Your guests will love customizing their portions to their taste preferences.

FAQ

1. Can I make this egg casserole ahead of time?

Absolutely! You can assemble the entire casserole the night before and refrigerate it covered. Simply add 5-10 extra minutes to the baking time since it will be cold when it goes into the oven.

2. How should I store leftovers?

Store leftover egg casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes or in a 325°F oven for 10-15 minutes until warmed through.

3. Can I freeze egg casserole?

Yes, this casserole freezes well for up to 3 months. Wrap it tightly in plastic wrap and aluminum foil before freezing. Thaw overnight in the refrigerator before reheating in the oven.

4. What can I use instead of ham?

Cooked bacon, crumbled sausage, or diced turkey are excellent substitutes for ham. For a vegetarian option, try using more vegetables or adding cubed tofu for extra protein.

5. Why did my casserole turn out watery?

A watery casserole usually means it wasn’t baked long enough or the vegetables released too much moisture. Make sure to pat your vegetables dry before adding them, and always test the center with a knife before removing from the oven.
