11 Healthy Breakfast Casseroles Under 300 Calories

Who said casseroles couldn't be healthy?

What could possibly beat the feeling of waking up to a home-cooked breakfast casserole? (Especially if it’s one of our top recipes.) Whenever I think of this cozy meal, I remember the morning when Grandma Doster—with worn-out rags serving as oven mitts—would bring out a cheesy, sausage-laden casserole for me and my brother to dig into. Inevitably two (or three) slices would make their way into my mouth. Though, I’d never knock Grandma—her extra cheesy breakfast pizza casserole wasn’t the best thing for my waistline.

Now that I’m cooking for myself, I ask: Is it possible to turn all of Grandma’s cozy goodness into a healthy dish?

Believe me, friends, it is.

It was love at first bite when I tried this sausage-vegetable egg bake submitted by home cook Cathy Banks from Encinitas, California. Seriously, it was like a light was shining down from heaven when my fork met this better-for-you breakfast dish. The recipe is made healthy by utilizing a few healthy ingredients.

Instead of classic pork sausage, Banks calls for lean turkey sausage. (I love the Jennie-O brand!) The recipe also calls for part-skim mozzarella. Now, you might call me a fool, but I don’t think there’s much of a difference in flavor between full-fat and low-fat cheese—especially when it’s baked and served in a dish like this. Last, the breakfast casserole is loaded with all the fresh veg that I adore. Bring on the mushrooms and chard, please! Best part? A single serving of Cathy’s casserole is about 250 calories. Even Grandma would approve of that.
