  • Covering or Not Cover: This is an option. I recommend not covering it so the topping can have that nice crisp edge. If you prefer to cook it covered be sure to uncover 10 to 15 minutes remaining, cook uncovered for that crisp crust on top.
  • Keep your potatoes frozen: No, there is no need to thaw the potatoes. They will cook frozen.
  • How to know when breakfast is done: once the outside edges become golden brown and the egg mixture in the middle is firm ( check by rocking the pan). Use a toothpick or knife to check if it is completely cooked through. You can also use a thermometer to check to see if the breakfast casserole has reached 165 degrees Fahrenheit.
  • Drain grease: if you are using any other meat in the breakfast casserole, be sure to drain the meat prior to adding it in the dish.
  • Gluten free: make this gluten free by keeping with this breakfast recipe. Check your labels on other ingredients to make sure.

  • Can you freeze a casserole? Yes, this is perfect for freezing. Make and bake your breakfast casserole. Once it has completely cooled down, place in an airtight container or ziplock bag. Lay flat in your freezer for up to 1 month. When ready to warm up, place on baking sheet frozen and bake until warmed through about 20 to 25 minutes.

  1. You say grease the pan, are you talking Crisco or can I use pam? It will be refrigerated over night so I’m not sure how the pam will hold up.

  2. Can I substitute like potatoes obrien( chopped potatoes with peppers ) instead of hash Browns? and also my family is small. Would I BA able to cut this recipe in half u think? And just cut down the baking time by half ? Thanks 🙂

    1. I personally like shredded potatoes and I am not sure how chopped potatoes would turn out. I just made this and halfed the recipe and kept the cooking time the same. It turned out great!

  3. You said leave the foil on..when asked way up in the beginning. Now you said “without the foil”. So which is it?

    1. Did I say with the foil? It is supposed to be baked with the foil on. Just made this yesterday and it turned out amazing!

      1. I have looked back through the responses and I never saw a response that said ‘without the foil’, always noted ‘WITH the foil’.
        Thanks for the recipe. I intend to try this with the hash browns and ham instead of my usual bread cubes and sausage.

  4. I was going to do this last night for my Bunco group tonight. I didn’t get a chance to. Will it be ok if I cook it right when I get home tonight and serve ??

      1. OK, now I’m confused, cook with or without the foil? Earlier in this thread you say to cook with the foil on. Thanks!

  5. I have also used frozen Potatoes O’Brien w the onions and green pepper in them . Makes for a very flavorful casserole. I thaw out before using them.

  6. I halved this recipe recently and it turned out great. I used whole milk instead of half and half. I am making it again but this time I want to add veggies (gr and red pepper, onion). Any advice? Thanks!

    1. I added saute’ed mushrooms, red bell pepper, red onions and spinach. I used chicken sausage, homemade frozen hashbrowns and three different cheeses I had in the fridge. I layered it like a lasagna, topping each layer with the different veggies and cheese. The final topping was cheese. I made sure to season each layer with salt, pepper and some crushed red peppers as I cooked them. Just now putting it in the oven. I’ll let you know how it turns out if you like.

  7. Hi there! Can this be baked the night before and reheated in the morning? I need this for an early brunch that is 2 hours away!! Thanks!

  8. 5 stars
    I am a vegetarian. Instead of meat, I used portabello mushrooms (rough chop). For the seasoned salt, I used Morton’s Nature’s Seasons. The casserole was delicious! My family loves it. Thank you!
