What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these you probably have on hand, and they come together beautifully to create that perfect cheesy, savory breakfast casserole.

• 6 large eggs, room temperature (for a fluffy custard base)
• 2 cups whole milk (or 1½ cups milk plus ½ cup cream for extra richness)
• 3 cups cubed day-old bread (white or sourdough works best; slightly stale is ideal)
• 2 cups shredded sharp cheddar cheese (I recommend Cabot for great melt and flavor)
• 1½ cups diced cooked ham (leftover ham or store-bought deli ham, cut into bite-sized pieces)
• 1 small yellow onion, finely chopped (adds sweetness and depth)
• 2 cloves garlic, minced (for a hint of savory aroma)
• 1 teaspoon Dijon mustard (optional, but adds a subtle tang)
• 1 teaspoon paprika (smoked paprika if you want a little smoky note)
• Salt and freshly ground black pepper to taste
• 2 tablespoons unsalted butter, melted (to coat the baking dish)
• Fresh parsley, chopped for garnish (optional, but pretty!)

Ingredient tips: Use firm, cubed bread for the best texture—too soft and it gets mushy. And if you want a dairy-free version, swap milk and cheese with plant-based alternatives like almond milk and vegan cheese. For a gluten-free option, use gluten-free bread. I’ve also found that using a good quality sharp cheddar really makes the flavor pop.

Equipment Needed

• 9×13-inch (23×33 cm) baking dish – a classic choice for casseroles; glass or ceramic both work well
• Mixing bowl – medium size for whisking eggs and milk
• Whisk or fork – for beating the eggs and milk together
• Knife and cutting board – for chopping ham, onion, and garlic
• Measuring cups and spoons – to keep ingredient amounts precise
• Skillet (optional) – if you want to sauté onions and garlic beforehand for extra flavor
• Aluminum foil – to cover casserole during baking if needed

If you don’t have a 9×13 dish, a similarly sized oven-safe casserole or baking pan will do. I’ve used both glass and metal pans, and each gives a slightly different crust texture—glass helps heat evenly while metal tends to brown edges faster. A silicone spatula is another handy tool for folding ingredients gently.

Preparation Method

1. Preheat your oven to 350°F (175°C). Butter your 9×13-inch baking dish generously with the melted butter to prevent sticking and add a touch of flavor.
2. Prepare the bread: Cube about 3 cups of day-old bread into roughly 1-inch (2.5 cm) pieces. Stale bread is perfect here because it soaks up the custard without falling apart.
3. Mix the custard: In a medium bowl, whisk together 6 large eggs and 2 cups whole milk (or 1½ cups milk plus ½ cup cream). Add 1 teaspoon Dijon mustard, 1 teaspoon paprika, salt, and pepper to taste. Whisk until combined and slightly frothy.
4. Prepare the fillings: Chop 1½ cups cooked ham into bite-sized cubes. Finely chop 1 small yellow onion and mince 2 garlic cloves. (Optional: sauté onion and garlic in a little oil or butter over medium heat for 3-4 minutes until softened and fragrant, then let cool slightly.)
5. Combine everything: In a large mixing bowl, toss the bread cubes, ham, (sautéed) onions, and garlic together. Pour the custard mixture over the bread mixture and gently fold to coat everything evenly. Let it sit for 10 minutes to allow the bread to soak up the custard. This step is key for a custardy, tender casserole texture.
6. Add cheese: Stir in 2 cups shredded sharp cheddar cheese, reserving a handful for topping later.
7. Transfer to baking dish: Pour the mixture into your buttered baking dish. Spread evenly and sprinkle the reserved cheese on top for a golden, bubbly crust.
8. Bake: Place the casserole in the preheated oven and bake for 45-50 minutes, uncovered. Check at 40 minutes—casserole should be puffed, golden brown on top, and a knife inserted in the center should come out clean.
9. Rest before serving: Once done, remove from oven and let it sit for 10 minutes. This helps the casserole set and makes slicing easier.
10. Garnish and enjoy: Sprinkle freshly chopped parsley on top if you like, slice into squares, and serve warm.

Pro tip: Avoid opening the oven door too often while baking; it can cause the casserole to deflate. Also, if you find the top browning too quickly, tent loosely with foil for the last 10-15 minutes of baking.

Cooking Tips & Techniques

Honestly, this casserole is pretty forgiving, but a few tricks will help you nail it every time. First, make sure your bread is day-old or slightly stale—fresh bread will get mushy and soggy. Letting the bread soak in the egg mixture for at least 10 minutes is crucial for that perfect custard texture.

Don’t rush the soaking step—you want the bread to absorb those flavorful eggs and cheese. When whisking eggs and milk, do it until fully blended but not too frothy; too much air can cause the casserole to puff and then collapse.

Using sharp cheddar adds just the right tang, but feel free to play with cheeses like Gruyère or Monterey Jack for a different flavor profile. If you sauté your onions and garlic first (which I highly recommend), it mellows their bite and adds a deeper flavor.

Watch your oven temp closely. Every oven bakes a little differently, so start checking at 40 minutes. And when it comes out, let it rest—trust me, it’s worth it. Slicing too soon can cause a messy, runny casserole.

Learned this the hard way: under-cooked casserole is a bummer, so if your knife isn’t clean, bake a little longer. Also, don’t skip the butter in the pan—it helps with browning and easy serving. Lastly, if you want to prep ahead, you can assemble the casserole the night before, cover it well, and bake in the morning.

Variations & Adaptations

This easy cheesy ham and cheese breakfast casserole is a great base recipe that you can tweak to suit your tastes or dietary needs. Here are a few variations I’ve tried and loved:

• Vegetarian version: Skip the ham and add sautéed mushrooms, spinach, and bell peppers for a veggie-packed casserole.
• Spicy twist: Add diced jalapeños or a dash of hot sauce into the custard for a little kick. Smoked paprika also amps up the smoky flavor.
• Low-carb option: Substitute the bread with cubed cauliflower florets or use a low-carb bread to keep it keto-friendly.
• Dairy-free adaptation: Swap milk for almond or oat milk and use vegan cheese. The texture changes a bit, but it’s still tasty.
• Seasonal flair: In the fall, add sautéed butternut squash or pumpkin puree; in spring, try fresh asparagus or peas.

Personally, I once added a handful of sun-dried tomatoes and fresh basil for an Italian twist—totally delicious and a nice change from the classic. Feel free to experiment with your favorite herbs and spices; this casserole is a blank canvas ready for your creativity.

Serving & Storage Suggestions

This casserole is best served warm, fresh from the oven or after a brief rest. It pairs beautifully with fresh fruit, a light green salad, or even crispy breakfast potatoes if you’re feeling indulgent. For beverages, a cup of strong coffee or a glass of fresh orange juice complements the savory flavors perfectly.

Leftovers? No worries. Cool the casserole completely, then cover tightly and store in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1-2 minutes or warm slices in a 350°F (175°C) oven for 10-15 minutes until heated through.

You can also freeze leftovers: wrap tightly with foil and place in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating. The flavors actually deepen a bit after resting, so I find the casserole tastes even better the next day.

Nutritional Information & Benefits
