4 Fundamental Elements

When gathering components for this recipe, I like to think about it as having 4 separate parts. From there, you may have enjoyable with variations.

  1. Greens
  2. Meat (or further greens)
  3. Starch for absorbing moisture
  4. Egg, cheese, & milk combination

Right here Are the Infinite Add-ins & Taste Choices

  1. Greens: Choose which greens you’d like within the dish. Usually, the preferred with visitors is bell peppers, spinach, and mushrooms. However I’ve additionally made this with broccoli/peppers, kale/mushrooms, and spinach/zucchini. Attempt to stick to three–4 cups of greens complete. Cook dinner the greens down with some flavor-enhancing onion and garlic.
  2. Meat: Company normally desire meat within the casserole, so I add sausage. Or attempt utilizing floor turkey, diced bacon, floor beef, or floor hen. I normally buy raw sausage for this and brown it with some dried rosemary or Italian seasoning to offer it a little bit further taste, however that’s non-obligatory. If the meat you’re utilizing is pre-cooked, similar to diced ham or shredded hen, you may combine it with the cooked vegetable combination earlier than layering it into the dish.
  3. Starch: Like when making breakfast strata, sausage stuffing, and cream cheese French toast casserole, the bread needs to be barely stale so it could take in moisture. Crusty sourdough is FANTASTIC right here. It’s also possible to use home made artisan bread, a loaf of French bread, crusty baguette, biscuits, bagels or home made bagels, and even day-old croissants (have you ever tried home made croissants?!). To make it gluten free, use gluten-free bread or potatoes.
  4. Eggs, milk, & cheese: Whisk a dozen eggs with a little bit half-and-half or milk and stir in some shredded cheese. Just like the greens and meat, use no matter cheeses you want finest, similar to sharp cheddar, pepper jack, feta, and/or smoked gouda.

Variations: One among my favourite variations of this recipe is every little thing bagel breakfast casserole. It’s a BIG HIT and persistently will get rave opinions. Or attempt my totally different technique/recipe for biscuit breakfast casserole with home made biscuits baked proper on prime.

Can I Use Potatoes?

Sure, you may exchange the bread with diced hash brown potatoes—the sort you discover within the freezer part of the grocery retailer. Company have *cherished* this model. Use about 3 cups (round 380g) of hash browns instead of the bread. You can additionally peel and cube contemporary potatoes, however you’ll have to rapidly prepare dinner them on the skillet for 10 minutes earlier than utilizing on this dish.

Do I Must Use Bread?

Bread or potatoes, sure. In addition to eggs, bread is the principle ingredient. To keep away from a spongey, moist dish, this breakfast casserole wants construction on the backside. You see, when eggs bake, they launch a variety of liquid. Chunks of crusty bread (or hash brown potatoes) take in some liquid so the casserole is chunky and textured, not flat and moist. In the event you’re in search of one thing with out this starchy addition, crustless vegetable quiche is a superb possibility.

As that’s scorching on the range, whisk the eggs, milk, and cheese collectively:

Now it’s time to assemble, and I’ve made this course of quite a bit simpler over time. Spoon all the greens/meat combination on prime of the bread. Pour the egg combination throughout that:

Success Tip: Refrigerate In a single day

At this level, you may both bake it instantly or refrigerate the casserole in a single day and for as much as 24 hours. Throughout this time, the flavors mingle collectively and the bread has an opportunity to absorb a number of the liquid and taste. Get up and all it’s a must to do is slide it into the oven. In the event you’re in a rush, I do advocate a minimum of half-hour within the fridge earlier than baking, in case you can spare it!

Bake till the sides are golden brown. As a result of it’s so egg heavy, the casserole puffs up within the oven like a cheesecake after which sinks again down because it cools. Cool for five–10 minutes earlier than slicing and serving.
