Bacon and Spinach Breakfast Casserole

Firstly, preheat your oven to a high temperature of 350 degrees Fahrenheit (or 175 degrees Celsius for those using metric measurements). Next, take some cooking spray and lightly cover a 9x13-inch baking dish to prevent any food residue from sticking to it.

Now, cook some bacon in a large frying pan over a medium-high heat level, stirring it occasionally until the entire piece is evenly browned. This should take around 10 minutes. Remove the cooked bacon from the pan and place it on a paper towel-lined plate to drain any excess grease. Chop the cooked bacon into smaller pieces and set it aside for later use.

In the same pan you used to cook the bacon, sauté sliced bell peppers and onions over a medium-high heat level until they become tender. This should take anywhere from 5 to 10 minutes, depending on your desired level of doneness.

Spread a layer of fresh spinach leaves across the bottom of the prepared baking dish, followed by your cooked bacon and sautéed bell pepper mixture.

In a separate bowl, whisk together some eggs using a fork until they become well-mixed. Add milk, garlic salt, and pepper to the eggs and continue whisking until everything is fully incorporated.

Pour the egg mixture over the bacon mixture in the baking dish, followed by a sprinkle of shredded Monterey Jack cheese and Asiago cheese.

Finally, place your baking dish in the preheated oven and bake until a knife inserted into the center comes out clean, taking anywhere from 35 to 45 minutes.
