As much as I love to cook, making breakfast usually feels like a chore. So I’m usually looking for ways to shortcut the process and still end up with delicious results.

Cue the slow cooker. I love making everything from breakfast casseroles, to French toast, to stuffed peppers to feed my family or to feed guests.

Most breakfast recipes, like this Denver Omelette Casserole only take a few hours to cook, so they are perfect if you get up early for a little quiet time and can toss this together.

Ingredients you’ll need:

  • frozen shredded hash browns
  • butter
  • eggs
  • milk
  • peppers
  • onions
  • cooked ham (leftover or lunchmeat is fine)
  • cheese

How to Make Denver Omelette Casserole in the Slow Cooker:

This is a super easy, layer up recipe that doesn’t require any additional cooking.

  1. Chop up the onions and peppers
  2. Dice up the ham
  3. Mix up the eggs
  4. Layer everything in the slow cooker!

Note: I like to add about half of the egg mixture, then top with the veggies and ham and then top with remaining egg so that the filling ends up more in the middle.

Best Slow Cooker for this Recipe

Any oval or rectangle slow cooker should work. I have not tried this with a round slow cooker. I used my 2.5 quart mini casserole slow cooker which was perfect.

If you use a 4-6 quart slow cooker you’ll need to reduce the cooking time as it may cook faster.

Can this be Prepped Ahead?

This makes a great meal prep recipe! I like to cook this up on the weekend and serve it up for my kiddos breakfast all week. Simply slice and store in an airtight container in fridge.

Reheat for 30-60 seconds per slice in microwave or until heated through.

It’s also possible to prep this up the night before and cook in the morning. Feel free to layer it all in the slow cooker liner and refrigerate overnight.

Be sure to remove the liner and let set out at least an hour before putting in the slow cooker to heat.

Can you Freeze Leftovers?

Yes. I suggest wrapping individual slices and storing in a freezer bag. Defrost in microwave then heat through to serve.

Equipment

2.5 quart mini casserole slow cooker

Ingredients

  • 5-6 oz frozen shredded hashbrowns
  • 4 tablespoons melted butter
  • 8 eggs
  • 1 tablespoon milk
  • 1/2 green bell pepper (diced)
  • 1/2 red bell pepper (diced)
  • 1 small yellow onion (diced)
  • 4 oz diced ham (I just used lunch meat!)
  • 4 oz shredded cheese
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper

Instructions

  • Spray slow cooker with nonstick spray
  • Spread hashbrowns evenly across bottom of slow cooker
  • Drizzle with melted butter
  • Beat together eggs and milk with salt and pepper and pour half of the mixture over the top
  • Sprinkle peppers, onions, and ham evenly over the top of the hashbrowns
  • Top with remaining egg mixture
  • Sprinkle cheese over the top of all of it
  • Cover and cook on high for 3 hours

Notes

  • If using a 4 quart or larger slow cooker, reduce cooking time as it will cook faster
  • You can make up the night before and cook in the morning. Make sure your slow cooker liner sits out to come to room temp before heating in slow cooker to prevent damage
  • Leftovers can be stored in the fridge up to 3 days or in the freezer for up to 3 months
  • I recommend wrapping slices individually before freezing

    Recipe says to use a 2.5 qt. mini-casserole crockpot. Comments indicate you used a 6 qt. oval crockpot. Which is correct??

      Hi Tim! Good eye! I’ve actually cooked this recipe in both and had good results each time. As noted, if you use a 4 quart or larger, it may cook a little faster.

    I don’t see whether to cook on high, low, or medium.

    Can you double it?

      I’m honestly not sure how well it would work if you double. It might be too thick to cook through evenly? Maybe if you used a casserole style slow cooker?

    Cleaning the crockpot after this near tasteless dish is not worth the fuss of making it. Buy a ring and place it in an iron skillet filling it with hashbrowns, eggs over easy on low heat in another small iron skillet makes a much better meal and a lot more sense!

      Hi Roger, thanks for the comment. If Denver omelets with the peppers, onions, and ham aren’t your taste than certainly some hash browns and eggs make another kind of great breakfast! Happy cooking 🙂
