Breakfast Casserole FAQS
Can you freeze breakfast casseroles?
Do you cover breakfast casserole when baking?
I bake this breakfast casserole uncovered.
Can you reheat a breakfast casserole?
When it’s time to reheat, allow the dish to come to room temperature before putting it into a hot oven. Preheat the oven to 350 degrees Fahrenheit. Cover a leftover egg-, potato- or meat-based breakfast casserole with a piece of foil so the moisture will not escape and to ensure even heating.

This was good but I would sprinkle a little salt on the potatoes before adding the cheese. I used turkey breakfast sausage patties, cubed and heated.
Make sure It is room temperature before putting it in the oven, and have the oven hot when you put it in to bake it. Bake the casserole on a lower rack and you shouldn’t have the problem with the dough
Can you use a aluminium disposal pan? And how much does this feed?
I”m sorry, but it was not good at all. None of my guests would eat it. I had to throw it away. I did substitute hash browns for the potatoes.
Can I use a disposable tin casserole pan for the casserole?
Did anyone have the issue of the milk and egg mixture seeping to/under the crescent roll dough? Half of my dough was able to get properly cooked, but the other half just looks & feels like a squishy nasty mess : ( I tried sealing the sides in a bit but I guess I didn’t realize how much I should have tried.
My husband made this for Christmas morning and we both love it. We enjoyed it so much that he is going to make it again for New Years morning but we are going to try it with ham and garlic and onion powder. I can’t wait!!
Wonderful!! I am so happy to hear that!
Will you make a vegan version with Just egg, vegan sausage (should it be patties or links), unsweetened almond milk, plant-based cheese ?
Do you thaw the hash browns?
No – they go in frozen.
Oh 5 stars! Great recipe!
Substituted sausage for cooked bacon and added garlic & onion powder, salt and pepper.
It was good but next time I am going to try it with goetta.
Do you cook the sausage before adding it to the dish?
Sausage should be cooked before adding to the dish!
I’m baking this dish right now. I love your ideas and recipes but really would have liked the measurements included in the recipe. i.e how many ounces of hash browns, how much milk etc. We will see in a few minutes
Just found the measurements in the recipe! My mistake. Thank you
