Ingredients & Preparation for Sweet Overnight Berry Breakfast Casserole

Berry Selection Essentials

Fresh berries are the star of this dish. Trim and clean your berries thoroughly before use. For frozen berries, thaw and drain excess liquid to prevent a soggy casserole. A mix of strawberries, blueberries, and raspberries creates a beautiful color palette and flavor profile.

Sweet Base Ingredients

• 1 loaf day-old bread, cubed (brioche or challah works best)
• 2 cups mixed berries (fresh or frozen)
• 8 large eggs
• 2 cups milk
• 1/2 cup maple syrup or honey
• 2 teaspoons vanilla extract
• 1/2 teaspoon cinnamon
• Pinch of salt
• Optional: lemon zest for brightness

Prepare the night before for the best flavor absorption. The bread will soak up all the sweet custard overnight for a perfect morning bake!

Pantry Staples

Don’t forget your baking essentials like maple syrup or honey for natural sweetness, vanilla extract for depth, and a touch of cinnamon for warmth. A squeeze of lemon juice can brighten the berry flavors without overpowering.

Step-by-Step Cooking Instructions for Sweet Overnight Berry Breakfast Casserole

Pre-Cooking Prep

Grease a 9×13 baking dish and arrange bread cubes evenly. Scatter berries throughout the bread layer, ensuring even distribution. In a large bowl, whisk together eggs, milk, sweetener, vanilla, cinnamon, and salt until completely combined.

Cooking Method

Pour the egg mixture evenly over the bread and berries, pressing gently to ensure all bread is soaked. Cover with plastic wrap and refrigerate overnight or for at least 6 hours. When ready to bake, preheat oven to 350°F. Remove plastic wrap and bake uncovered for 45-55 minutes until golden brown and custard is set.

Doneness Check

The casserole is done when the center is set and no longer jiggly. A knife inserted in the center should come out clean, and the top should be golden brown. The internal temperature should reach 160°F for food safety.

Resting

Allow the casserole to rest for 10-15 minutes before serving. This resting period lets the casserole set up properly, making it easier to slice and serve while maintaining its structure. 📌 Discover more delicious recipes on Bikren Cook’s Pinterest — your next favorite meal is waiting!

Pro Tips for Perfect Sweet Overnight Berry Breakfast Casserole

Avoiding Soggy Casserole

Use day-old bread that’s slightly dried out to better absorb the custard without becoming mushy. Don’t overcrowd with berries, as too many can release excess liquid. If using frozen berries, toss them in a tablespoon of cornstarch to absorb excess moisture.

Tool Recommendations

A glass baking dish works best for even heating. A whisk for properly combining the custard ingredients ensures smooth texture. Measuring cups and spoons for accuracy will help maintain the perfect sweet-to-tart balance.

Storage & Reheating

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 60-90 seconds or place the entire casserole (covered with foil) in a 325°F oven for 15-20 minutes until warmed through.

Flavor Variations for Sweet Overnight Berry Breakfast Casserole

Tropical Twist

Add diced mango and coconut flakes for a vacation-inspired breakfast. Substitute coconut milk for regular milk for extra tropical flavor.

Low-Sugar Option

Use stevia or monk fruit sweetener instead of maple syrup. Choose berries like strawberries and raspberries which are naturally lower in sugar than others.

Fall Harvest Version

Try our Apple Pie Cupcakes for inspiration and swap berries for diced apples and add extra cinnamon and nutmeg for a cozy autumn breakfast casserole.
