Sausage Breakfast Casserole Recipe FAQs
What type of breakfast sausage should I use?
Absolutely! You can use any breakfast sausage you prefer, whether it be pork, turkey, or even a plant-based option for a healthier twist. I often recommend using a flavorful pork sausage, but if you’re looking for a leaner choice, turkey sausage works brilliantly too.
How should I store leftover Sausage Breakfast Casserole?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy, you can reheat individual portions in the microwave or warm the casserole in the oven at 350°F until heated through, which usually takes about 20-25 minutes.
Can I freeze Sausage Breakfast Casserole?
Yes, you can freeze the fully assembled, unbaked casserole for up to 2 months! Make sure to wrap it tightly in aluminum foil or plastic wrap. When you’re ready to bake it, simply thaw it overnight in the fridge, and then bake according to the recipe instructions, adding a few extra minutes to ensure it’s heated through.
What if my casserole turns out soggy?
Very! If you find your casserole soggy, it might be due to excess moisture from the vegetables. To fix this, sauté any added vegetables—like spinach or broccoli—thoroughly before incorporating them into the casserole. Additionally, letting the assembled casserole sit at room temperature for about 30 minutes before baking can help prevent cracking and ensure an even bake.
Can my pets eat this casserole?
While your furry friends might give you those pleading eyes, it’s best to keep this casserole away from them. Ingredients like onions and heavy cream could be harmful or upsetting to their tummies. If you’re looking to give your dog a treat, consider setting aside a bit of plain, cooked sausage without any seasoning for a special Puppy Snack!
Is this Sausage Breakfast Casserole suitable for a gluten-free diet?
Absolutely! You can make this dish gluten-free by using gluten-free hash browns and ensuring that your breakfast sausage and dijon mustard are also gluten-free. It’s a fantastic way to keep everyone included at the brunch table!
