How to Make this Simple Breakfast Casserole
- Preheat your oven to 350 degrees.

- Grease a 9"x 9" baking dish (using oil, spray or butter), then pour the mixture in. Sprinkle the remaining pepper jack cheese on top.
- Bake uncovered at 350 degrees for 30-40 minutes, or until completely set and golden brown on top.
- Once baked, remove from the oven and let cool for about 5 minutes before slicing.
- Serve with salsa, sour cream, hot sauce or sliced avocado. Enjoy!
Ingredients and Tips for this Sweet Potato Breakfast Casserole Recipe
- Eggs - any kind of large eggs will work great.
- Sweet Potatoes - shred your sweet potatoes using the small shred section of a cheese grater. It takes a little more time but ensures that your potatoes are fully cooked.
- Milk - any form of milk that you have on hand will work.
- Ham - we like using honey ham for this recipe, but you can use your favorite variety.
- Green Onions - the flavor of the green onions becomes even more robust if you allow this to sit in the fridge overnight, making it even more delicious. You’ll want to use mostly the white part of the onions, but adding in some of the green definitely won’t hurt.
- Red Bell Pepper - these add so much color and the little bit of spice is delicious. If you prefer, you can use green or orange, too.
- Dijon Mustard - this gives a nice rounded flavor, feel free to use a slightly larger squirt if you are a mustard fan.
- Cheese - we use both shredded cheddar and pepper jack, but if your family doesn’t like spice you can use all cheddar, or substitute mozzarella, smoked gouda or Swiss.
How to Make this Breakfast Casserole the Night Before
This Sweet Potato Breakfast Casserole makes the perfect overnight breakfast casserole. Allowing the flavors to meld together in the fridge has delicious results and actually seems to improve the flavor so if you have time, by all means, make this a day ahead.
Just follow the directions for mixing your eggs, sweet potatoes, milk, ham, onions, red pepper, mustard and cheeses, except hold off on sprinkling the last half of pepper jack cheese onto the top, and cover your baking dish with plastic wrap.
Store in the refrigerator for up to 24 hours, then the next morning pull out your baking dish and let it come to room temperature. Preheat your oven as directed, sprinkle with the rest of your cheese and put into the oven to bake once your dish is at room temperature.

Variations and Other Sweet Potato Breakfast Recipes To Try
- Sweet Potato Egg Bake Cups - these make a great meal prep breakfast. Just spray muffin tins with baking spray, then fill almost to the top with your egg mixture. Sprinkle a little cheese over the top, and bake at 350 degrees for about 15-18 minutes (depending on the size of your muffin tins), or until the eggs are set and the cheese is golden brown. Store leftovers in the fridge and reheat in a warm oven or microwave for about 30 seconds.
- To Make Vegetarian - instead of the ham, you could try substituting a vegetarian “ham” or “sausage” crumble, simply increase the amount of red bell pepper to use a full pepper.
- Different Cheese - if pepper jack isn’t your thing, try substituting mozzarella, smoked gouda, Swiss or even goat cheese.
Also be sure to try this Baked Denver Omelet. It's so easy to make and is a great recipe for a crowd. For something on the sweeter side, my family absolutely loves this Sweet Potato Casserole with a pecan streusel topping. It’s really almost more of a dessert, but sometimes that is just what you want.
How to Make in the Slow Cooker
- Spray your slow cooker first!
- Prep all of your ingredients, and whisk together your eggs, milk and mustard in a separate bowl.
- Add the sweet potato, ham, green onions and bell pepper to the bottom of the slow cooker and spread out evenly. Sprinkle the cheddar cheese and half of the pepper jack over the top.
- Pour the egg mixture over the top of everything and move around a bit with a spoon or spatula to combine.
- Sprinkle the rest of the cheese evenly over the top and put the lid on.
- Cook for 6-8 hours on low, or 2 ½ -3 hours on high, until the egg mixture is completely set.
