This Overnight Ham Bake requires basic pantry staples that create extraordinary results:

Main Components:

  • 12 large eggs (room temperature works best)
  • 2 cups diced ham (honey-glazed adds sweetness)
  • 3 cups shredded sharp cheddar cheese (divided)
  • 8 slices thick-cut white bread, cubed
  • 2 cups whole milk (2% works as substitution)
  • 1 cup heavy cream (half-and-half acceptable)

Flavor Builders:

  • 1 medium yellow onion, finely diced
  • 2 tablespoons Dijon mustard
  • 1 teaspoon garlic powder
  • 1/2 teaspoon paprika
  • Salt and black pepper to taste
  • 2 tablespoons fresh chives, chopped

Preparation Time: 20 minutes (evening before)
Overnight Chilling: 8-12 hours
Baking Time: 45-50 minutes
Total Active Time: 65-70 minutes

Step-by-Step Instructions

Prepare the Base Layer

Begin by greasing a 9×13-inch baking dish thoroughly with butter. Next, arrange cubed bread evenly across the bottom. The bread should form a solid foundation without gaps. Subsequently, sprinkle half the diced ham over the bread, followed by 2 cups of shredded cheese.

Create the Egg Mixture

Meanwhile, crack eggs into a large mixing bowl, whisking until completely smooth. Then, add milk, cream, Dijon mustard, and seasonings. Whisk vigorously for 30 seconds until well combined. The mixture should appear pale yellow and slightly frothy.

Add Aromatics

Heat a small skillet over medium heat, then sauté diced onions until translucent, about 4 minutes. Allow them to cool slightly before folding into the egg mixture. This step adds depth without overwhelming the dish.

Assemble the Casserole

Pour the egg mixture slowly over the bread and ham layers. Press down gently with a spatula to help bread absorb liquid. Sprinkle remaining ham and cheese on top. Cover tightly with aluminum foil, then refrigerate overnight.

Morning Baking Process

Remove casserole from refrigerator 30 minutes before baking. Preheat oven to 350°F (175°C). Bake covered for 30 minutes, then remove foil and continue cooking 15-20 minutes until center sets and top turns golden brown.

Beverage Pairings:

Common Mistakes to Avoid

These Quick Breakfast Ideas pitfalls can ruin your morning:

Inadequate Chilling Time:
Rushing the overnight process prevents proper flavor melding. The bread needs 8+ hours to absorb liquid completely. Consequently, shorter chilling results in soggy bottoms and uneven cooking.

Overcrowding Ingredients:
Adding too much filling prevents even egg distribution. Stick to recommended proportions for best results. Additionally, overstuffing causes longer cooking times and uneven doneness.

Temperature Troubles:
Cold casseroles straight from refrigerator to oven crack dishes and cook unevenly. Always allow 30 minutes of room temperature adjustment. Furthermore, overbaking creates rubbery textures and dried edges.

Inadequate Seasoning:
Underseasoned egg mixtures taste bland despite quality ingredients. Salt the mixture adequately, as bread and cheese absorb much seasoning. Taste-test before chilling when possible.

Storing Tips for the Recipe

Maximize freshness and safety with proper storage:

Refrigerator Storage:
Cooked casserole keeps 3-4 days when covered tightly. Cool completely before refrigerating to prevent condensation. Store individual portions in airtight containers for grab-and-go convenience.

Freezer Options:
Freeze baked casserole up to 2 months wrapped in plastic and foil. Alternatively, freeze unbaked assembled casserole for make-ahead convenience. Thaw overnight before baking, adding 10 extra minutes cooking time.

Reheating Methods:
Microwave individual portions 60-90 seconds until heated through. Oven reheating at 325°F for 15-20 minutes maintains better texture. Cover with foil to prevent drying during reheating process.

FAQs

Can I prepare this casserole two days ahead?
Absolutely! Assembled casseroles keep well for 48 hours refrigerated. The extended chilling time actually improves flavor development, making it perfect for holiday planning.

What’s the best bread type for this recipe?
Thick-cut white bread or challah work excellently because they absorb liquid without falling apart. Avoid thin sandwich bread, which becomes mushy during overnight chilling.

How do I know when the casserole is fully cooked?
Insert a knife in the center, it should come out clean. Additionally, the internal temperature should reach 160°F (71°C) for food safety. The top should be golden brown and slightly puffed.

Can I make individual portions instead?
Yes! Divide mixture among greased muffin tins or ramekins. Reduce baking time to 20-25 minutes. Individual portions are perfect for portion control and freezing convenience.

What if my casserole looks too liquidy before baking?
This is normal after overnight chilling. The bread continues absorbing liquid during baking. However, if extremely watery, drain excess liquid before baking to prevent soggy results.
