Bacon & Onion Breakfast Casserole

Holly

A baked egg and cheese casserole, this is easy to make and can be prepared ahead. Great for serving guests or for a special breakfast. We also love prepping it ahead and having quick breakfasts ready all week.

Equipment

1 Mixing bowl
1 Whisk
1 Blender or Food Processor
1 9 x 13 Casserole Dish

Ingredients

1 onion
4 tbsp butter
6-8 slices bread or a package of frozen hash brown potatoes
1 lb. bacon cooked and crumbled or diced
2 c. or up to 1 lb of shredded Cheddar cheese or other cheese if you prefer
8 eggs beaten well
1½ c. milk
1 tsp. salt
¼ tsp. black pepper
1¼ t. dry ground mustard

Just before baking top with:

3 c. cornflakes, crushed crushed. Gluten free alternatives are: corn chex, rice chex, tortilla chips. Leave off for lower carb option.
½ c. butter, melted

Instructions

Preheat oven to 300°F.
Caramelize onion by sautéing until browned. Use medium-high heat and stir infrequently.
Grease baking dish.
Tear bread into pieces and place into 9×13 greased pan. Or pour and spread out frozen hash browns in baking dish.
Layer bacon, onions, and then cheese over bread or potatoes.
Beat eggs with milk, salt and mustard—blender or food processor works best for this.
Pour mixture over bread, meat, and cheese (make sure bread is well-covered).
Cover and chill 8 hours or overnight. (Optional–see notes.)
Uncover and sprinkle with cornflakes and then drizzle with melted butter.
Bake at 300° for 60 minutes, or until set (bubbly).
Cut into squares and serve. We love serving with salsa, hot sauce, or chili garlic sauce at the table.

Notes

This casserole is best when made ahead and then just pop it in the oven when you’re ready to serve it. However, I’ve put this casserole together and baked it immediately many times and it still tastes fantastic.
