Directions

Step 1: Butter a 9x13-inch baking dish. Cut and fit 8 slices of bread to cover the entire bottom of the dish.

Step 2: Cover the bread with slices of Canadian bacon and sharp Cheddar cheese.

Step 3: Cut and fit the remaining 8 slices of bread to completely cover the bacon and cheese.

Step 4: In a bowl, whisk the eggs with salt and black pepper.

Step 5: Whisk in the dry mustard, minced onion, diced green and red bell peppers, Worcestershire sauce, and hot sauce into the egg mixture.

Step 9: Preheat the oven to 350F (175C).

Step 10: Once the oven is ready, pour the melted butter evenly over the casserole and sprinkle corn flakes over the top.

Step 11: Bake in the preheated oven until the casserole is set and lightly browned, about 1 hour.

Step 12: Let the casserole stand for 10 minutes before serving to allow it to set properly.

Cook's Note

There are many ways to personalize this dish. I like using red and green bell peppers because they add a festive touch, but you can easily add spinach instead. Additionally, I prefer using grated cheese and spreading it over the Canadian bacon instead of using cheese slices.

I stumbled upon this recipe while searching for ways to use up leftover corn flakes, and I must say, I absolutely love it! Since I'm not a morning person and I often host overnight guests, this dish is perfect for me. As an Italian, I sometimes substitute prosciutto, mozzarella, and basil for the Canadian bacon and cheddar. If you're a fan of tomatoes, consider adding sun-dried tomatoes instead of or alongside some of the peppers, as fresh tomatoes can make it too watery. This recipe works beautifully and I want to thank Toby for sharing it.

I really enjoyed this recipe! I added my own twist to it by sautéing the onions first and opting for the Holiday edition of Rice Krispies instead of red and green peppers and corn flakes. Wishing everyone a Merry Christmas!

This dish is a staple for our family on Christmas mornings, but I love it so much that I enjoy making it all year round! I usually skip the peppers, opt for shredded cheese, and sometimes swap out the back bacon for regular honey ham. Following the recipe exactly yields fantastic results! It does puff up in the oven, but don't worry, it settles down once it's done baking. The corn flakes and butter topping is essential - it adds such a delicious touch! I agree with another reviewer that reducing the butter on top will make it dry, so stick to the original recipe. Overall, this dish is a winner!

Here is the rewritten review: I found this recipe to be very adaptable. I particularly enjoyed the balance of the egg and milk custard mixture to the bread. I opted for cubed ham and grated cheddar instead of sliced, and I decreased the amount of Worcestershire sauce to half a teaspoon. Next time, I would skip adding extra salt as the ham provided enough saltiness for my taste. I appreciated the flavor that the onions and peppers brought, and the crispy cornflake topping was a nice touch. I also reduced the amount of butter used.

This has been one of my favorite recipes for years now. I prepare it every couple of weeks and find it perfect for breakfast, lunch, dinner, or a snack. Doubling the recipe and freezing it is a game-changer - just pop it in the microwave and it's ready to eat in minutes. I've also added extra onions, pepper, and all the other flavorful ingredients listed in the recipe to enhance its taste.

I was quite disappointed with this dish, to be honest. I had heard so much about the Christmas wife saver recipe and was really looking forward to trying it out. However, the texture was too mushy for my taste, and the flavor didn't really impress me. Despite following the recipe exactly, it just didn't live up to the hype for me. I doubt I'll be making it again in the future.

This is absolutely fantastic! It has now become our go-to brunch tradition after unwrapping all the gifts. Thank you for sharing the recipe!

I absolutely adore this casserole recipe and have been preparing it for many years. I make sure to always remove the crusts from the bread. Occasionally, I switch up the type of bread I use - sourdough, multigrain, or whatever I have on hand. I've substituted ham slices for pea meal bacon before, and I've also experimented with various types of cheese. It all depends on what ingredients are in my fridge the day before.
