Step‑by‑Step Instructions for Overnight Egg Bake
Step 1: Preheat the Oven
Begin your journey toward a delicious Overnight Egg Bake by preheating your oven to 350°F (175°C). This temperature will create the perfect environment for baking, ensuring that your egg casserole cooks evenly and develops a lovely golden layer on top. As the oven heats, gather your ingredients to streamline the preparation process.
Step 2: Prepare the Baking Dish
While your oven warms up, grease a 13 x 9-inch baking dish with butter to prevent sticking and add a hint of flavor. This step ensures that your Overnight Egg Bake will slide out easily once baked, ready for slicing and serving. Take a moment to admire the dish as you prepare, picturing the delightful layers to come.
Step 3: Chop the Vegetables and Protein
Next, slice the green onions and chop the bell peppers, broccoli, mushrooms, and any meat you’re using into bite-sized pieces. Aim for uniform pieces so they cook evenly. This colorful array of ingredients will create a vibrant and hearty base for your egg bake, bursting with flavor and nutrients.
Step 4: Sauté the Vegetables
In a skillet, melt a tablespoon of butter over medium heat. Add the green onions first, allowing them to sauté until fragrant, about 1-2 minutes. Then, toss in the remaining veggies and cook for another 2-3 minutes until slightly softened but still a bit crunchy. This step enhances their flavors and adds depth to your Overnight Egg Bake.
Step 5: Layer the Ingredients
Once the vegetables are ready, begin layering them in your greased baking dish. Start by spreading the sautéed veggies evenly across the bottom, then sprinkle your choice of cooked meat and shredded cheese on top. The layering process adds texture and ensures that each slice of your casserole is packed with flavor.
Step 6: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, whole milk, parsley, salt, and pepper until fully blended. This mixture is the heart of your Overnight Egg Bake, bringing everything together. Pour it carefully over the layered ingredients in the baking dish, ensuring even coverage for a beautifully cohesive casserole.
Step 7: Refrigerate Overnight
Cover the assembled dish tightly with plastic wrap or aluminum foil, and place it in the refrigerator. Allowing the Overnight Egg Bake to rest overnight lets the flavors meld beautifully. If you’re short on time, a minimum of 30 minutes will still yield a delicious outcome.
Step 8: Bring to Room Temperature
When you’re ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes. This helps the dish to bake evenly and ensures a perfect consistency. As it warms slightly, enjoy the anticipatory aroma of the ingredients mingling.
Step 9: Bake the Casserole
Place the baking dish in the preheated oven and bake uncovered for 55-65 minutes. You’ll know it’s done when the edges are set, and the center is just slightly jiggly, giving it that classic casserole texture. A light golden-brown top will signal it’s ready to be savored.
Step 10: Cool and Serve
After baking, let your Overnight Egg Bake sit for a few minutes to cool before slicing. This resting period allows for cleaner servings and enhances the overall presentation. Gather your friends and family to share this heartwarming dish that promises to brighten any brunch table!
