Cheese and Onion Bread Casserole

Mastermind Weekend 1/16

Hey there!

I'm Tina

I’m the owner of Carrots ‘N’ Cake as well as a Certified Nutrition Coach and Functional Diagnostic Nutrition Practitioner (FDN-P). I use macros and functional nutrition to help women find balance within their diets while achieving their body composition goals.


An in-depth, 4-week reverse dieting course for women who feel like their metabolism has slowed down, think they might have hormonal imbalance and can’t lose weight no matter what they do.

I’m a huge fan of cooking big ol’ casseroles during the work week. They’re easy to make and taste great as leftovers, especially packed in lunches or for busy nights when you only have time to reheat dinner.

This Cheese and Onion Bread Casserole is a vegetarian dish that combines French bread, onions, and cheddar cheese into one-dish to make a delicious, hearty meal. I used cheddar and a tiny bit of Gruyere, but you could easily substitute different cheeses in this dish.

Makes: 8 servings

Cook: 15 minutes 
Bake: 45 minutes 
Prep: 10 minutes 


4 eggs
3 cups low-fat (1%) milk
1/4 teaspoon ground nutmeg
1 loaf French bread (about 16 inches long), cubed (about 8 cups)
2 tablespoons olive oil
3 large onions (about 1-1/2 pound) sliced
1/2 teaspoon sugar
1/2 teaspoon salt
1/4 teaspoon black pepper
2 cups shredded Cheddar cheese


1. Whisk together eggs, milk and nutmeg in large bowl. Add bread cubes. Let mixture stand 30 minutes, stirring occasionally.
2. Heat oil in large nonstick skillet. Add onion, sugar, salt and pepper; cook over medium-low heat until onion is very tender, 15 minutes.
3. Heat oven to 350°. Coat 13 x 9 x 2-inch baking dish with nonstick cooking spray.
4. Spoon half of bread mixture into baking dish. Top with half of onion mixture. Repeat with the remaining bread and onion. Sprinkle with cheese.
5. Bake at 350° for 45 minutes or until puffed and golden. Let cool slightly before serving.



  1. Yumm!! I will definitely try this out when I”m at college because it looks SUPER college friendly both in terms of cost and preparation!

  2. I think this will definitely be on the menu at my place next week. I’m a big fan of freezing the leftovers in individual portioned sizes, and this will work great for that as well as being tasty! 🙂

  3. This looks like one of those meals that tastes even better as leftovers. Thank you for the suggestion:)

  4. Quick, Easy, Cheap (at least where i live) and delicious! i’m a total cheese and bread fan so this would taste like heaven!! i’m gonna try it out tonigh :))))
