Frequently Asked Questions

Can I make this hash brown breakfast casserole ahead of time?

Absolutely! This casserole can be assembled the night before and refrigerated overnight. Simply follow the instructions until step 5, cover the baking dish with plastic wrap or foil, and refrigerate. In the morning, preheat the oven, remove the plastic wrap or foil, and bake as directed. This makes it perfect for busy mornings or when you want to have a hassle-free breakfast ready to go.

Can I use fresh hash browns instead of frozen?

Yes, you can use fresh shredded hash browns if you prefer. Just make sure they are well-drained to avoid excess moisture in the casserole. You may need to adjust the cooking time slightly since fresh hash browns might cook faster than frozen ones.

Can I add additional vegetables to the casserole?

You can add extra vegetables to the casserole to enhance the flavor and nutritional value. Popular choices include diced onions, sliced mushrooms, spinach, or even jalapeños for a spicy kick. Just make sure to adjust the cooking time accordingly to ensure the vegetables are cooked to your liking.

Can I freeze the leftovers?

You bet you can freeze the leftover casserole. Allow it to cool completely and place them in freezer-safe container. To reheat, simply thaw the portions overnight in the refrigerator and bake in the oven until heated through.

    Also, Thank you so much for providing such detailed nutritional information. I wish everyone did that.

    For the heart patient and the diabetic in my household I cook for, the addition of just how much a serving size is in your recipes would also be very helpful.

    Good morning,

    I am about to make this recipe.

    For future reference (since you wonโ€™t see this and respond in then next few minutes!):

    First, you wrote, “Reheat your leftover casserole in the fridge for about 1-1.5 minutes.โ€ Did you mean in the microwave?

    Second, today I will stick to your recipe proportions, but what will happen if I add additional eggs next time?

    Thanks

      Thank you for the helping with they type, lol, I’ll fix that and if you add a few more eggs it might just need to bake another 5-10 minutes depending on how many you add!
