To make the Overnight Croissant Breakfast Casserole, you need: - 6 large croissants, torn into bite-sized pieces - 6 large eggs - 2 cups whole milk - 1 cup shredded cheddar cheese - 1 cup cooked and crumbled sausage (optional) - 1/2 cup diced bell peppers (red and green) - 1/2 cup chopped green onions - 1 teaspoon garlic powder - 1 teaspoon dried thyme - Salt and pepper to taste - Fresh parsley for garnish Adjust the ingredient amounts based on how many servings you want. For a smaller dish, you can cut the recipe in half. If you have more guests, double the recipe. You can also swap out ingredients. If you don't have croissants, use day-old bread instead. If you want a lighter option, use egg whites and low-fat milk. Choosing the right croissants matters. Fresh croissants give a soft texture. Look for ones with a golden brown crust. If using frozen croissants, let them thaw before using. Fresh vegetables add flavor. Choose vibrant bell peppers and crisp green onions for best results. To start, gather your ingredients. You will need croissants, eggs, milk, cheese, and veggies. Tear the croissants into bite-sized pieces. This makes it easy for everyone to enjoy. Toss them in a large bowl with the diced bell peppers and green onions. If you want meat, add the crumbled sausage. Mix well and set this aside. Next, let’s make the egg mixture. In another bowl, whisk the eggs and whole milk. Add the garlic powder, thyme, salt, and pepper. Mix until it is smooth and creamy. Now, pour the egg mixture over the croissant mix. Gently fold the croissants into the egg mix. This helps each piece soak up that tasty egg. After that, stir in half of the cheddar cheese. This adds a nice cheesy flavor. Time to transfer everything to a baking dish. Grease a 9x13 inch dish before adding the mixture. Spread it out evenly. Cover it tightly with plastic wrap. You can let it chill in the fridge overnight. If you are in a hurry, chill it for at least four hours. When ready to bake, preheat your oven to 350°F (175°C). Take the dish out of the fridge. Let it sit for about 15 minutes to reach room temperature. This helps it bake evenly. Sprinkle the remaining cheddar cheese on top. Bake uncovered for 35 to 40 minutes. Look for a golden brown top and puffy center. When done, take it out and let it cool for 5 to 10 minutes. This makes slicing easier and prevents burning. Enjoy your delicious Overnight Croissant Breakfast Casserole! For the full recipe, check the earlier section. To get the best overnight croissant breakfast casserole, you need to soak the croissants well. First, tear the croissants into bite-sized pieces. Then, mix them with your veggies and meat.

This way, it has time to soak without becoming mushy. When serving your casserole, think about what to pair it with. Fresh fruit, like berries or sliced oranges, brightens up the plate. You can also serve it with a side of crispy bacon or sausage. These add a nice crunch to the soft casserole. For drinks, fresh juice or coffee works great. A light tea can also complement the dish well. Plating your casserole nicely makes a big difference. Use a large, colorful platter to display it. Cut the casserole into squares for easy serving. Sprinkle fresh parsley on top for a pop of green. This not only adds color but also fresh flavor. You could also add a dollop of sour cream or yogurt for a creamy touch. A pretty presentation makes breakfast feel special. {{image_2}} You can change the flavor of your Overnight Croissant Breakfast Casserole easily. Adding meats like ham or bacon gives a hearty touch. If you prefer no meat, try mushrooms or spinach for a veggie option. Cheese is another great place to play. Swap cheddar for Swiss or feta for a tangy twist. If you have dietary needs, don't worry! You can make gluten-free versions. Use gluten-free croissants or bread. For dairy-free, almond or oat milk works well. You can also replace eggs with mashed bananas or flaxseed meal for a vegan option. Using seasonal veggies can bring new life to the casserole. Try adding zucchini in summer or butternut squash in fall. For festive times, think about cranberries or pumpkin spice to make the dish special. You can truly make this meal fit any season or occasion. To store leftovers, let the casserole cool to room temperature. Then, cover it tightly with plastic wrap or foil. This helps keep it fresh. You can also use an airtight container. The casserole lasts in the fridge for 3 to 4 days. Make sure to check for any signs of spoilage before eating. Yes, you can freeze the casserole. It’s best to freeze it before baking. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. To reheat frozen portions, let them thaw overnight in the fridge.

1 teaspoon dried thyme

Salt and pepper to taste

Instructions
 

Prep the Croissants: In a large mixing bowl, gently toss the torn croissant pieces with the diced bell peppers, green onions, and crumbled sausage if using. Set aside.

    Make the Egg Mixture: In a separate large bowl, whisk together the eggs, whole milk, garlic powder, dried thyme, salt, and pepper until well combined.

      Combine Ingredients: Pour the egg mixture over the croissant mixture and gently fold to ensure all croissant pieces are soaked in the egg mixture.

        Add Cheese: Stir in half of the shredded cheddar cheese, mixing evenly throughout.

          Prepare for Overnight Chill: Transfer the mixture into a greased 9x13 inch baking dish, spreading it out evenly. Cover tightly with plastic wrap or a lid.

            Refrigerate: Place in the refrigerator overnight or for at least 4 hours to allow the croissants to soak up the egg mixture.

              Bake: Preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it come to room temperature for about 15 minutes.

                Add Cheese and Bake: Sprinkle the remaining cheddar cheese on top and bake uncovered for 35-40 minutes, or until the casserole is puffed and golden brown in the center.

                  Cool and Serve: Allow to cool for 5-10 minutes before slicing. Garnish with freshly chopped parsley for a touch of color.
