Recipe Ingredients

- Egg Mixture: This is made by mixing a full carton of large eggs, milk, and seasonings.
- Onion: Diced and added for a hearty and flavorful touch.
- Seasonings: Salt, black pepper, garlic powder, and onion powder.
- Cheddar Cheese: Save time by using a bag of shredded sharp cheddar cheese or purchase a block and shred it yourself, I recommend this for the best melting finish. (Find the full recipe in the recipe card below the photos).

Have you ever doubled this recipe? If so, how long was the cooking time?
I have not doubled it, it wouldn’t fit if doubled. Also, when egg type dished are doubled, it’s hard to get the center to finish before the edges burn.
Hi, what ido you think cooking time would be if I halved the recipe?
Thanks
I’m guessing about 4 hours on low. It’s hard to say without testing.
Thank you!
Have you ever attempted the recipe with less eggs? My diva (9 y/o) doesnโt like eggs but I love the protein they addโฆso would love to see this less eggy for her but not sure if itโs even possible?
I have not tested with less eggs, it may be too dry.
You cld mix in some other cheese like ricotta or cottage cheese and maybe some xtra half and half but not enough to make it too soupy
Would the cooking time change if I made 4 servings (half the recipe)?
Thanks, Joann
I have not tested a half recipe, but yes, the cooking time would be less.
Can this be prepared the night before, leave the insert in the fridge, and then and then start it early in the morning?
I was looking for the answer to the same question!
You can, though you run the risk of the slow cooker cracking when it’s put on the heat. I have never had this happened, but have heard of it.
Hi. Can you tell me the name of the slow cooker u use. I love your recipes
