Spinach and Mushroom Egg Casserole
Hi everyone! It’s Jennifer from Town and Country Living back to share a quick and easy breakfast casserole that can be saved and reheated for eating later. I’m always looking for ways to add more vegetables to my diet, so rather than toss in the proverbial breakfast sausage, I opted for spinach and mushrooms to add flavor to this egg casserole.
 Some breakfast foods are heavy and sit in your stomach like a lead weight all morning. I’m always looking for lighter options. This spinach and mushroom egg casserole is a variation of a Paula Deen recipe. If you watch her show, you know she tends to fix calorie-laden food. I cut out some of the fat in my version and substituted healthier choices.
 This dish has your basic breakfast ingredients so no need to add any side dishes to the meal. You’ll start preparing this recipe by frying up some hash browns and sweet onions for a few minutes, then spread them in your casserole dish followed by a layer of bread cubes.
 Using the same pan, saute your onions and spinach until the spinach leaves start to wilt.
Carefully spread your veggies over the hash browns and bread cubes. Your egg mixture comes next and will get absorbed somewhat into the bread cubes, which makes them soft and tasty after the casserole is done baking.
 Cheese is sprinkled on top. I cut back on the amount of cheese used in the original recipe, but honestly, you could cut it down even more if you want to further reduce the calories and fat.
You’ll bake it in a 350 degree oven for about 35 minutes and remove just before it starts to brown.
 This is a great dish to serve for breakfast or brunch. Easy to make, and it’s packed with flavor!
