Grab some bacon and cook it until it’s just the way you like it — extra crispy or a little flimsy. Your choice.

Rough chop the bacon and throw it in with eggs.

    Here’s what baffles me.
    Prep time – 10 minutes.
    Chop 3 cups of spinach, chop 2 cups of mushrooms, cook and chop 6 slices of bacon, grate 1 cup of cheese, etc. Not just this recipe – almost all of them.

    If whisking and mixing and spraying and pouring is the 10 minutes, what exactly do you call the labor intensive stuff, you know, when you’re not a master chopper, grater like Rachel Ray?

    It would just help novice cooks if you guys could give it a name. And also a time for it (for amateurs).

    1. Maggie, prep time in a recipe considers that the chopping, measuring, etc. have been done and the ingredients are at the level described in the recipe ingredient list. Prep time just figures the time it takes to follow the steps in the recipe instructions. While it may take you 30 minutes to prep the ingredients, someone else may take 45 minutes or 20 minutes to prep.

  2. I don’t like mushrooms but I like that your recipe uses fresh spinach. If I replace the mushrooms with a red bell pepper will it still turn out?

  3. This is the first egg casserole I found that doesn’t call for milk. I just want to verify that milk is not required.
