This is a wonderfully tasting recipe that is not too difficult. A large iron skillet is helpful.
Thank you for your kind words Jonda. So glad you enjoyed the frittata.
Delicious!!!!
Love this Frittata. A simple, quick, and delicious meal!
I did modify it a bit by adding fontina cheese, onion and bell pepper. Very satisfying!
Thank you.
Altered few ingredients to fit my taste, but overall wonderful recipe. Thank you!
Delicious thank you!!!
Swapped out the butter for vegan, milk for almond milk and dairy free cheese and it was absolutely delicious. Thank you for the recipe.
I made this recipe in a glass pie pan and it came out perfect with little clean up. The only issue I have is the amount of time in the oven, I used a counter top oven and had to add 8 minutes to the cooking time. I also have substituted ham for the bacon and took out the mushrooms and added spinach.
Made this exactly as recipe said. OMG so good. Will def make again. Thank you!
can you transfer mixture from frying pan to baking pan then pour the remainder indegrid. if you don’t have a cast iron pan?
Hi Julie,
You certainly can.
Wow, it looks like pizza and I love it so much. Wonderful recipe to eat.
This recipe was so yummy! Mmmm
Glad you enjoyed it Kathy! Thanks for stopping by 🙂
This frittata is SO good! I like to make it on a Sunday and have it for breakfast over the next four days. It’s a great portable option that I can heat up at work. It’s delicious with half an avocado.
Did you just use button mushrooms or does it matter? Thanks.
Hi Erin,
I prefer to use button mushrooms, but you can use whichever type you like.
