First things first, grab your stale bread and tear or cut it into roughly 1-inch pieces. I usually just use my hands; it’s quicker and less precise, which is totally fine for this dish. Spread the bread evenly into a greased 9x13 inch baking dish. This is where the foundation for your delicious Easy Breakfast Casserole begins, honestly, it sets the stage for all that eggy goodness. I always make sure to grease the dish really well, because nobody wants stuck-on casserole!

Next, in a large skillet over medium heat, crumble and cook your breakfast sausage until it's nicely browned. Drain off any excess grease – this is important, you don't want a greasy casserole! Then, add your chopped onion and bell pepper to the skillet and cook until softened, about 5-7 minutes. I sometimes add a pinch of red pepper flakes here for a little kick, because, why not? The smells starting to fill my kitchen at this point are just heavenly.

In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper. Whisk until it’s all combined and a little frothy, but don't overdo it, or your eggs can get tough. This step is where all the flavors come together for your Easy Breakfast Casserole. I always give it a good sniff; you can already tell it's going to be good. Make sure there are no streaks of egg white left, that’s key!

Sprinkle the cooked sausage and veggie mixture over the bread in the baking dish. Then, evenly sprinkle about half of your freshly grated cheddar cheese over the sausage and veggies. Finally, carefully pour the egg mixture over everything, making sure to get it as evenly distributed as possible. I usually press down gently with a spatula to ensure the bread soaks up all that lovely liquid. This is crucial for a moist and flavorful Easy Breakfast Casserole.

Now, you have a choice! You can either cover the dish with plastic wrap and refrigerate it for at least 4 hours, or even overnight, which is what I usually do for a stress-free morning. Or, if you're like me and sometimes make spontaneous decisions, you can bake it right away! If chilling, let it sit out for about 20-30 minutes before baking. I always forget this step, oops, but it still turns out great.

Preheat your oven to 375°F (190°C). Uncover the casserole, sprinkle the remaining cheddar cheese over the top, and bake for 45-55 minutes, or until it's golden brown and puffed up, and a knife inserted into the center comes out clean. Oh, the smell of it baking is just incredible! Let it rest for 5-10 minutes before slicing and serving. This resting time is important, it helps the casserole set and makes for cleaner slices. This Easy Breakfast Casserole is worth the wait!
