    Based on picture, looks like a 7"×11" dish. Or, an 8" or 9" square would work with the volume of ingredients.

    I live in Canada and we don't have "heavy" whipping cream.

    Can we replace it with (liquid unsweetened) whipping cream or something else?

    Excellent egg dish for either a brunch or dinner! I used the regular whipping cream I buy for my coffee. Also added spinach like the recipe suggested. Tastes like a quiche.

    This is one of my favorites! I eat this more as a lunch meal than breakfast, with a green salad. I also added spinach to the recipe, it taste awesome!! Its very easy to cook, normally i use a mix of all kind of cheese, nota only cheddar. I certainly recommend this recipe.

    Cristi, what they are referring to is just whipping cream (33 - 36%) which we, of course, can find in all grocery stores in Canada. Hope that helps.

    Christi , I tried one recipe a week or so ago and it called for heavy whipping cream but also offered a substitute of using sour cream . I used the sour cream and it came out terrific . I am going to try this as a substitute more often .

    Any replacement for cream and cheese for non dairy option? Or can I not put into the recipe? Can this recipe freeze before serving if making for a week.

    I originally used the 9 x 13 and we loved this recipe for months, but when I only had my 8 x 8 to use, I was shocked at how much better it was. This recipe is the best breakfast casserole ever! Definitely use the 8 x 8. If I use the larger pan, it will be to double the recipe for company.

    if you use a cast iron skillet, you don’t need another dish to bake the casserole. also, if you just cook it til set on top of the stove then broil for a minute, you’re meal won’t take 40 minutes.

    This may be a stupid question but I’m new to all this and trying to do lots of meal prep so I don’t find myself stuck. Will this last all week in the fridge or can this be frozen for later?

    Going to try making this for breakfast, thinking of using a medium deep frypan, and grilling to set the top. Will add a little chorizo, chopped into small pieces, & spinach. Also some chopped leftover Brussel sprouts.

    Maybe a dumb question, but when placing contents of Skillet in baking dish, should the butter and bacon grease be included or discarded?

    Personal preference! Some people may have more grease left over than others and some may not like the extra grease added to their dish.

    One of my favorites! I made an extra-large batch this 2nd time I made this. Had to use regular whipping cream (not heavy). I drained the grease before adding to the baking dish. I didn't grease the glass dish because the grease from the bacon and butter served to grease the pan. I also added a batch of spinach. Turned out fantastic.

    Yes, this can be frozen. Most recipes and meals will store in the freezer for 2-3 months without issue, some longer than that.

    I would try making it in advance and then refrigerating it and waiting to bake it until just before serving. Enjoy!

    Made this but omitted butter, used egg whites for half of the eggs, skipped the salt & light cheese (works better for my calories & macros). It was really delicious & we will make again.

    I really liked this one. It is so smooth and moist. I've made it 3 times now but substitute in 1/4 diced onion for the onion salt. I just added the onion in with the and bacon mushrooms when they are almost done so I don't burn the onion. It tastes great!

    So, I made this again as stated in my previous comment but this time I used 1/2 cup of heavy cream and subbed in 1/2 cup of sour cream. I loved it, the sour cream really kicked it up a notch!

    For the woman who commented she cannot get heavy whipping cream in Canada....I am very sure she meant whipping cream period.
    The word heavy is used because many people think they can exchange a heavy cream such as whipping cream with 10% or less creams and you can't. Pretty sure heavy is there just to clarify it for readers.

    Loved it! For 8 egg size recipe, I used 8X11 corningware casserole baked 25 minutes, then covered with foil and baked another 10 minutes. It was perfect, except over-done on the bottom edges. I omitted the butter because plenty of grease in the bacon, cooked 2 separate batches of the bacon, mushrooms, and spinach in my iron skillet and used most of the bacon grease in the casserole which is very filling and doesn't taste greasy, but the bacon flavor is quite "loud." Maybe that is what makes it so good!

    Microwave works great for reheating recipes like this. If yours is a high wattage microwave, you may want to try at about 70% power.
