Breakfast Bundt Cake Casserole Ingredients
Here’s everything you’ll need to create this scrumptious delight!
For the Base
• 6 cups bread cubes – prefer day-old for the best texture in your Breakfast Bundt Cake Casserole.
• 1 cup breakfast sausage or bacon – cooked and crumbled for that savory punch.
• 1 cup onion – sautéed to bring out rich, sweet flavors.
• 1 cup bell pepper – sautéed for a vibrant, earthy taste.
• 1 cup shredded cheese – mild cheddar or mozzarella works beautifully in this dish.
For the Egg Mixture
• 6 large eggs – the foundation for a fluffy, custard-like filling.
• 2 cups milk – adds creaminess and moisture to the casserole.
• 1 teaspoon salt – enhances all the delicious flavors in the dish.
• ½ teaspoon pepper – a touch of spice to balance the richness.
• 2 tablespoons maple syrup or honey – optional, but adds a hint of sweetness if desired.
Step‑by‑Step Instructions for Breakfast Bundt Cake Casserole
Step 1: Prepare the Bread
Start by cutting your day-old bread into bite-sized cubes and spreading them evenly on a baking sheet. If you prefer a slightly toasted texture, place the baking sheet in a preheated oven at 350°F (175°C) for about 10 minutes, watching closely until the bread is light golden and slightly crisped. This step enhances the flavor and texture of your Breakfast Bundt Cake Casserole.
Step 2: Cook the Sausage and Vegetables
In a large skillet over medium heat, cook the breakfast sausage or bacon until crispy, which should take about 5-7 minutes. Once cooked, remove the meat and let it drain on a paper towel. In the same skillet, sauté the onions and bell peppers for 3-5 minutes until they are soft and fragrant, creating a savory base for your casserole.
Step 3: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, salt, and pepper until everything is well combined and frothy. If you choose to add sweetness, stir in the maple syrup or honey at this stage. This egg mixture will be the creamy binding element that envelopes all the delicious ingredients in your Breakfast Bundt Cake Casserole.
Step 4: Combine the Ingredients
Gently fold the toasted bread cubes, cooked sausage or bacon, sautéed onions, bell peppers, and shredded cheese into the large mixing bowl with the egg mixture. Using a spatula, carefully stir everything together until the bread is thoroughly coated with the egg mixture, ensuring that each piece is drenched in flavor.
Step 5: Prepare the Bundt Pan
Generously grease a bundt pan with cooking spray or butter to prevent sticking. Transfer the mixture from the bowl into the bundt pan, spreading it evenly. Press it down lightly to ensure it bakes uniformly in the oven, creating a beautiful, cohesive Breakfast Bundt Cake Casserole.
Step 6: Bake
Place the bundt pan in the preheated oven set at 350°F (175°C) and bake for 45-50 minutes. The casserole is ready when it is golden brown on top and set in the center, which you can check by inserting a toothpick—if it comes out clean, you're good to go!
Step 7: Cool and Serve
Once baked, remove the Breakfast Bundt Cake Casserole from the oven and allow it to cool in the pan for about 10 minutes. This cooling time makes it easier to unmold. Carefully invert the pan onto a serving platter, slice, and serve warm. Optionally, enjoy with toppings like Greek yogurt or sour cream for extra flavor.
Storage Tips for Breakfast Bundt Cake Casserole
Fridge: Wrap leftover slices tightly in plastic wrap or store in an airtight container for up to 3 days. This will keep your Breakfast Bundt Cake Casserole fresh and tasty.
Freezer: For longer storage, you can freeze the casserole for up to 2 months. Wrap individual slices securely in foil, place them in a freezer bag, and label them for easy identification.
