How to Make Ina Garten’s Easiest EVER Overnight Breakfast Casserole in 7 Simple Steps!

Are you often craving a stress-free morning meal? If so, you’re not alone! Many individuals struggle to find that perfect breakfast balance between deliciousness and ease. Fortunately, you can turn your weekday mornings from chaotic to effortless. Today, I’m going to show you how to Make Ina Garten’s Easiest EVER Overnight Breakfast Casserole! This recipe will not only satisfy your taste buds but also free up time for those who cherish those morning moments.

Ingredients List

To whip up this delightful breakfast casserole, gather the following ingredients:

• 8 large eggs: Fresh is best!
• 2 cups milk: Whole milk adds creaminess, but you can substitute with almond or oat milk for a lighter option.
• 1 loaf of crusty bread: Sourdough or French bread works beautifully.
• 1 cup grated cheese: Cheddar is traditional, but feel free to experiment with Gruyere or feta for a different flavor profile.
• 1 cup diced cooked ham or sautéed vegetables: Choose between protein and plant-based options.
• Salt and pepper to taste: Elevate the flavor with some fresh herbs if you like!

Timing

Preparation for this casserole takes approximately 20 minutes, followed by overnight soaking in the refrigerator for at least 6 hours, and finally, baking for about 50 minutes. In total, that’s less than 90 minutes of active work, making this recipe around 20% faster than many traditional breakfast casseroles!

Step-by-Step Instructions

Step 1: Prepare Ingredients

Start by gathering your ingredients on the kitchen counter. This makes the process smooth and ensures you don’t forget anything! Whisk the eggs and milk together in a large bowl until fully combined.

Step 2: Cube the Bread

Cut your crusty bread into 1-inch cubes. This can be done the night before if you want to save some time!

Step 3: Combine Everything

Add the bread cubes to the egg mixture, and gently fold them in to ensure they’re well-coated. This is where the magic begins as the bread soaks up those glorious flavors! Mix in your cheese and preferred fillings (ham or veggies).

Step 4: Season It Up

Sprinkle salt and pepper into the mixture to taste. You can also add a dash of your favorite herbs like thyme or rosemary to elevate the dish’s flavor profile.

Step 5: Refrigerate Overnight

Transfer your mixture into a greased baking dish. Cover it tightly with foil and place it in the refrigerator overnight. This allows all the ingredients to meld beautifully.

Step 6: Preheat and Bake

When morning arrives, preheat your oven to 350°F (175°C). Bake the casserole, still covered with foil, for about 30 minutes, then remove the foil and continue baking for another 20 minutes until golden brown.

Step 7: Serve and Enjoy!

Once done, let it cool for a few minutes before slicing. Serve warm, and enjoy with a side of fresh fruit or a dollop of Greek yogurt.

Healthier Alternatives for the Recipe

Storing Tips for the Recipe

If you have leftovers (which is rare!), store them in an airtight container in the refrigerator for up to 3 days. You can also freeze portions for up to 2 months—just reheat in the oven without thawing, covered with foil, to retain moisture.
