I wasn’t planning to post this recipe yet but when I made it for the second time in two weeks I decided you need the recipe for this Slow Cooker Ham, Cheese and Veggie Frittata now. With Christmas just over a week away, this easy crock pot frittata is a perfect dish to serve for Christmas breakfast or a holiday brunch.

You can prep this frittata ahead of time and start it cooking in your slow cooker. Then it’s completely hands-off so you can enjoy time with family and friends. Once the eggs are finished cooking, switch your slow cooker to the warm setting so the frittata will stay hot while guests help themselves to brunch.

This frittata is inspired by the flavors in a Denver omelet, one of my favorite things to order when I go out to breakfast. The frittata is filled with ham, cheddar, bell peppers and onions. It’s a delicious combination!

The second time I made this frittata I used a chopped Yukon gold potato in place of the ham to keep it vegetarian. There are so many options for the mix-ins for this frittata. I’ve listed a few more ideas below.

This recipe wasn’t a hit with my kids, since they like their eggs made with just cheese. Which means that whenever I make this Slow Cooker Ham, Cheese and Veggie Frittata we end up with leftovers. Not a bad problem to have at all!

I store the leftover frittata in the refrigerator and heat it up for breakfast for myself for the next few days. It’s a great meal prep option!

Tips for making this Slow Cooker Ham, Cheese and Veggie Frittata:

  • I recommend cooking this frittata on your slow cooker’s low setting. I tested it on high and the edges were a little over done. If you need it to cook quickly, you can try 1 1/2-2 hours on high, but watch it carefully.
  • I like to serve this topped with extra shredded cheese. Cheddar, pepper jack and mozzarella are all delicious.
  • You can customize this recipe by using different mix-ins. You don’t need to pre-cook the vegetables before adding them to the slow cooker. Some ideas are: sweet potato cubes (chopped small), russet or Yukon gold potato (chopped small), green onion, broccoli (chopped small), chopped spinach, chopped kale, or salsa (jarred, not fresh).
  • If you’re serving a large crowd, I think you could 1 1/2 this recipe. It might take a little longer for the eggs to cook through.
  • Try my French Toast, Veggie Quinoa Frittatas or Easy Breakfast Casserole next! You can prep the casserole the day before to save time in the morning.
