I first created this recipe when I was looking for a tasty breakfast that could use up some of my Christmas leftovers.

That year, we celebrated a traditional Filipino Christmas dinner with Jamon de Bola, a wet-cured ham, and Queso de Bola, an Edam cheese. 

So what to do with leftover ham and cheese? How about yummy keto frittata muffins!

I wanted to have an easy breakfast for all my house guests. These little bites were the perfect solution.

I was able to make a big batch all at once and then store them in the refrigerator. They were a big hit with the whole family.

I used Jamon de Bola and Queso de Bola because that’s what I had on hand. But this recipe is delicious with any style of ham and cheese! 

Step by Step Directions

These tasty egg muffins are one of my favorite breakfasts because they come together easily!

We’ll start with the egg frittata mixture:

  • In a pan, fry the ham in olive oil for 2 to 3 minutes each side. 
  • Remove from heat. Once the ham has cooled slightly, dice into small cubes.

  • In a mixing bowl, beat the eggs until fluffy. 
  • Add the cubed ham, chopped peppers, and cheese. Season with salt and pepper, then mix.

Next, simply pour the mixture and bake:

  • Pour the egg mixture into silicone molds or a greased muffin tray, leaving a bit of space at the top. 
  • Sprinkle grated mozzarella on top. You can also add more ham and peppers on top if desired.
  • Bake for 5 to 8 minutes at 350°F or until muffins are cooked through. To tell if they’re done, insert a toothpick at the center of the muffin. If no egg clings, your muffins are ready. If the tops are browning too quickly, you can also cover with tin foil.
  • Once cooked through, remove from the oven and allow to cool for 1 to 2 minutes before removing from silicone molds or muffin tray.

Storing Leftovers

I really like to make food ahead, especially around the holidays. It just makes everything so much easier. 

These low-carb frittata muffins are great to whip up ahead of time. Simply store them in the refrigerator, then reheat in the microwave or oven toaster for 1 to 2 minutes to serve.

They’re so nice to have if you’re trying to feed a lot of house guests. Or, whip up a batch on Sunday for an easy breakfast for you and your family all week!

You can also freeze them for longer storage. Again, just reheat in the microwave or toaster oven when you’re ready to serve.

Muffin Size

I love the way these muffins look as minis. They’re so cute! 

The small size makes them perfect appetizers as well. I usually make 30 to 36 mini muffins when I use this recipe.

Of course, you don’t have to make these mini size. You could do standard size muffins or even one big ham and cheese frittata.

Just make sure to adjust the baking time so the egg fully cooks. You may also want to cover the top with tinfoil so it doesn’t burn while the inside is still cooking.
