Loaded Breakfast Casserole
This is one loaded breakfast casserole! It’s made with eggs, roasted sweet potato, crispy bacon, breakfast sausage, onion, bell pepper, garlic, and the perfect amount of seasoning. Serve it up on the weekends, meal prep it for the week, or make it ahead of time for special occasions and holidays, like Christmas!
Who says a hearty breakfast casserole means store-bought hash browns and lots of cheese? Oh no, this one’s loaded with far better ingredients that are just as filling, and provide vibrant color to an otherwise brown and yellow meal. With the addition of roasted sweet potatoes, bell pepper, onions, bacon, and sausage, this casserole is the perfect all-in-one meal to start your day.
This easy breakfast casserole makes for a delicious weekend breakfast, it’s ideal for meal prep, and it’s perfect for special occasions and holidays like Christmas morning, or Easter brunch. You can easily feed the entire family (and then some), but you may not have much in the way of leftovers as it always gets devoured!
What’s In This Breakfast Casserole
A great mix of protein, carbs, and fats to keep you full!
- Sweet Potato: Roasted with some spices in the oven makes it crispy on the outside, creamy on the inside.
- Bacon: Crispy bacon makes everything taste better and works well with breakfast sausage.
- Breakfast Sausage: I’m using a slightly sweet breakfast sausage. But feel free to go for a mild, medium, or even spicy flavor.
- Spices: A combination of garlic powder, paprika, and cumin takes your roasted sweet potatoes to the next level.
- Onion: I like to use yellow onion for its subtle sweetness.
- Bell Pepper: You can use any color, but I love green for the contrast in color to the sweet potato.
- Fresh Garlic: For that savory punch of flavor.
- Eggs: Binds all the ingredients together with a delicious egg base.
- Milk: You can use either dairy or dairy-free to make the eggs nice and fluffy.
- Cheese: This is optional, but I personally love just a little sprinkle of sharp cheddar on top.

How To Make This Loaded Breakfast Casserole
While the ingredient list may seem long, it’s much easier to make than you think. You’ll be multi-tasking when it comes to prepping the ingredients and using both the oven and stove top at the same time. And once that’s all done, just mix everything together in the casserole pan and bake away.
Roast the bacon and potatoes. Preheat the oven to 400F and toss the diced sweet potatoes with olive oil, garlic powder, paprika, cumin, salt, and pepper. Then, add slices of bacon to a sheet pan. Pop both those items in the oven and cook the bacon for 18-20 minutes.
Once the bacon is done, take it out and place on paper towels to dry. Then continue roasting the sweet potato for an additional 15 minutes.
Cook the breakfast sausage, bell pepper, and onion. On medium-high heat, sauté the breakfast sausage until browned, then place in a 9×13-inch casserole pan. Drain off a bit of the sausage grease, then sauté the bell pepper and onion for 5 minutes. Add the minced garlic and sauté for another minute. Add the mixture to the casserole pan.
Stir everything together. Mix the sausage, bacon, bell pepper, onions, and sweet potato in the casserole pan and season with salt and pepper.
Add in the eggs. Whisk together the egg mixture and pour it over the meat and veggies.
Bake and serve. Cook for 25-30 minutes until the edges are golden and the center is cooked through. Then slice into squares and keep on reading for a few ways to garnish and serve!
Ways To Serve
Oh yeah, this casserole is mouthwatering on it’s own. But if you want to spruce it up a bit for guests or make it an even heartier meal – here’s a few easy ideas to keep up your sleeve.
- Garnish with greens. Top it off with sliced green onions, microgreens, or chopped herbs such as parsley.
- Pair with avocado. Slice up some avocado, add it to each plate, and sprinkle a bit of black pepper on top.
- Sprinkle cheese. If cheese is your thing, add some crumbled goat cheese or feta cheese on top.
- Add a side salad. Amp up the greens in your meal by quickly tossing leafy greens (such as spinach, arugula, or my massaged kale salad) in a lemon vinaigrette and serving on the side.
Dietary Options
If you don’t add cheese, this breakfast casserole is Whole30 and paleo approved. But if you’re looking to make this vegetarian, here’s a few ingredients to switch up.
- Use a dairy-free milk to mix with the eggs before pouring into the casserole.
- Swap the bacon and breakfast sausage for more vegetables such as roasted Brussels sprouts, broccoli rice, cauliflower rice, or sauteed Swiss chard.
Meal Prep And Store
Once you make this casserole, it means several meals are done for the week – for either breakfast, lunch or dinner! What more can someone with a busy weekday schedule ask for? Here’s a few ways to store it for future enjoyment:
- To eat throughout the week: Store in the fridge in an airtight container for up to 4-5 days. Then simply reheat in the microwave for about 1 minute.
- To freeze for later: Just place parchment paper in between the casserole pieces in your freezer-safe container (to prevent them from sticking together). The breakfast casserole will last for several months in the freezer. And when you’re ready to eat it, either thaw the night before in the fridge or let it defrost for a bit at room temperature then microwave it for 1-2 minutes, or until warmed through.

Loaded Breakfast Casserole with Sausage
Ingredients
- 1 pound sweet potato, peeled and diced into 1/2" cubes
- 1 tablespoon olive oil
- 1/4 teaspoon garlic powder
- 1/4 teaspoon paprika
- 1/4 teaspoon cumin
- salt and pepper
- 8 ounces bacon
- 1 pound breakfast sausage, mild, medium or spicy, your choice
- 1/2 large onion, diced
- 1 green bell pepper, deseeded and diced
- 2 cloves garlic, minced
- 12 large eggs
- 1/3 cup milk, dairy or dairy-free
- optional: shredded cheese and green onion for garnish
Instructions
- Preheat your oven to 400F/200C and get a 9x13 casserole pan out. On one baking sheet pan, toss the diced sweet potato with olive oil, garlic powder, paprika, cumin, salt, and pepper. Set aside.
- On another sheet pan, add slices of bacon. Then place both the sweet potato and bacon in the oven and cook for 18-20 minutes, or until the bacon is done. The bacon will be done first, so keep an eye on it and remove it from the oven when it's done, and place on paper towels to dry. Stir the sweet potato and continue cooking it for another 15 minutes.
- While the sweet potato is cooking, cook the breakfast sausage in a pan on medium high heat. Once it's browned, remove it with a slotted spoon and place it in the casserole pan.
- Drain off all but a tablespoon of grease from the pan, then saute the onion and bell pepper for 4-5 minutes. Add the minced garlic and saute another 30 seconds. Transfer the onion and bell pepper to the casserole pan.
- Remove the sweet potato from the oven and add it to the casserole pan, with the crumbled bacon, onion, and bell pepper. If you'd like to add cheese, you can add it to the casserole pan now.
- Stir all of the ingredients in the casserole pan together. Feel free to season with more salt and pepper.
- In a mixing bowl, stir the eggs with the milk.
- Pour the egg mixture on top of the meat and vegetables. Cook for 25-30 minutes, or until the center is cooked through and the edges are slightly golden. You can test the center with a toothpick.
- If you'd like, garnish with green onion, or herbs. Then serve warm with sliced avocado, toast, or a side salad.
Lisa's Tips
- One pound of sweet potatoes is usually one medium to large sized sweet potato. If it's slightly over, that's fine as well.
- I always recommend heavy duty baking sheets in the oven, so that they don't warp. They're definitely worth purchasing!
- And here's a great casserole pan, if you're looking for a new one.
Unfortunately the measurement button for metrics doesn‘t work. Every time I try to use it, I‘m being sent to the top of the page without any change to the quantities. I just wanted to let you know.
I‘m going to try and make the recipe this week. It seems really delicious!
Thanks for letting me know, Stefy! We’re actually in the process of making some website tweaks right now and hope to have that fixed shortly. :)
I made this one for myself but ended up having my whole family sneaking bits off it! It’s an absolutely delicious recipe – perfect for breakfast, lunch and dinner. Thank you Lisa! My only wish is to get the measurement fixed to showcase the metric system. It seems to be down and it would be super handy to not have to google what every US customary measurement is in the metric system :)
Hi Jen – There is actually a metrics button you can click on above the bulleted ingredients list! But, I’m glad you and the whole family loved this recipe!
Loved this casserole. Ate on it all week. Had it for breakfast and lunches. You can cut it into relatively small chunks as it’s seriously satiating.
It really is the best meal prep option! So glad you loved it.
Hello this sounds like a dumb question. But is the nutrition facts per serving?
Yes! The nutritional facts will always be per serving :)
Made this for Christmas morning 2020 and my boyfriend was asking for it again by New Years so definitely a new rotation recipe.
Thanks, Lisa!!
Wonderful! Glad you both enjoyed this casserole so much :)

Glad you ended up loving this breakfast casserole Mai! :)
Just made this delicious dish. It is amazing and so flavourful! No cheese needed. Thank you Lisa
Wonderful! Glad you loved this casserole recipe :)
If I want to half the recipe to make a smaller portion in a 9×9 pan, what would the cooking time be? Looks delicious!
I’d probably start checking if it’s done about 10 minutes earlier. Enjoy!
Absolutely fabulous. Worth the effort, SO delicious, perfect sweet-savory-healthy breakfast!

Hi Therese – so happy you enjoyed this recipe! Merry Christmas!
Hey Lisa,
Just made this breakfast casserole and it was delicious!! We loved it! I added some mushrooms and mustard greens cause I had some from my CSA box and then had to add in 4 extra eggs to the mixture but it turned out fantastic. Thanks for a great recipe. We’ve got leftovers for Christmas Eve and Day. Have a blessed Christmas.
Wonderful! The more ingredients the merrier in this recipe. Glad you loved this Sonya :)
Definitely a good breakfast casserole. However, I left the cumin out and used smoked paprika. Thank you for your awesomeness Lisa!
Glad you enjoyed this casserole Mark!
Thank you for the recipe. I really like your creative, healthy and easy recipes. I am happy to watch your clips, dishes and decorating… thank you.
And I want to ask your round plate. Could you let me know the casserloe plate?
Thanks so much Lee! You can find this casserole pan linked in the Shop page on my website :)
What a fabulous gluten free option!
Would white onion work
Yes! You can use whichever onion you’d like :)
if you wanted to substitute something for the sweet potatoes, what would you recommend? Regular cubed potatoes?
I have a few suggestions written in the blog post, but you can always do regular potatoes, other vegetables, or more of the existing ingredients.
This is the perfect addition to my breakfast! I love how it’s loaded with everything I need to start the day!
It’s delicious, filling, and the perfect way tp start Christmas morning :)

Sounds so delicious! Can’t wait to try this recipe with my family.
Thank you for the recipe. I made it tonight since I had all the ingredients and it was pretty good. I had the breakfast sausage links so I just put in oven then cut them into small pieces. I still used the grease to fry the onions and peppers.
Amazing! Glad this casserole turned out to be a success :)
Lisa that is wonderful deliciousness! Love all the ingredients and how easy it is to create a beautiful masterpiece breakfast!
