How to Make Holiday Brunch Casserole
Follow these simple steps to prepare this delicious Holiday Brunch Casserole:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and spray a 9×13-inch baking dish with nonstick cooking spray, so your casserole doesn’t stick like that last piece of tape on a gift.
Step 2: Cook the Meat
In a skillet over medium heat, cook the bacon or sausage until crispy. Once done, drain excess fat on paper towels and chop it into bite-sized pieces as you daydream about your ideal breakfast situation.
Step 3: Sauté the Veggies
In the same skillet, add a sprinkle of love (and a little olive oil if needed) and sauté the diced onion until translucent. Toss in the fresh spinach and cook until it's wilted, holding on to all those savory flavors (about 2 minutes). Just wait until you see how those greens contribute to the dish's beauty.
Step 4: Whisk the Eggs
In a large bowl, whisk together the eggs and milk until thoroughly combined. Feel free to belt out your favorite tune as you add a sprinkle of salt and pepper to make this mixture sing.
Step 5: Combine the Ingredients
Now the fun begins! Stir in the cooked meat, sautéed vegetables, and half of the shredded cheese into the egg mixture. Pour this colorful blend into the prepared baking dish and marvel at how it looks like a culinary masterpiece in progress.
Step 6: Bake and Serve
Sprinkle the remaining cheese on top and place your casserole in the oven to bake for 30-35 minutes. The magic happens as it rises and turns golden brown. Trust me; your kitchen will smell like a cozy diner. Once it's set in the center, take it out, let it cool for a moment, and get ready to serve this marvel of a dish.
Finally, gather your loved ones and slice this delightful casserole. Serve it warm, and perhaps pair it with some fruity mimosas or a hot cup of coffee to elevate the experience. Get ready for compliments from your family and friends!
