4 Foremost Parts

When gathering substances for this recipe, I like to consider it as having 4 separate parts. From there, you’ll be able to have enjoyable with variations.

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

Right here Are the Countless Add-ins & Taste Choices

  1. Greens: Choose which greens you’d like within the dish. Typically, the preferred with company 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 often desire meat within the casserole, so I add sausage. Or attempt utilizing floor turkey, diced bacon, floor beef, or floor hen. I often buy raw sausage for this and brown it with some dried rosemary or Italian seasoning to offer it a bit additional taste, however that’s non-compulsory. If the meat you’re utilizing is pre-cooked, equivalent to diced ham or shredded hen, you’ll be able to 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 ought to be barely stale so it might probably take in moisture. Crusty sourdough is FANTASTIC right here. You too can 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 bit half-and-half or milk and stir in some shredded cheese. Just like the greens and meat, use no matter cheeses you want greatest, equivalent to sharp cheddar, pepper jack, feta, and/or smoked gouda.

Variations: Considered one of my favourite variations of this recipe is the whole lot bagel breakfast casserole. It’s a BIG HIT and constantly will get rave evaluations. Or attempt my completely different methodology/recipe for biscuit breakfast casserole with home made biscuits baked proper on prime.

Use about 3 cups (round 380g) of hash browns instead of the bread. You possibly can additionally peel and cube recent potatoes, however you’ll must rapidly cook 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 primary ingredient. To keep away from a spongey, moist dish, this breakfast casserole wants construction on the backside. You see, when eggs bake, they launch plenty 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 case you’re searching for one thing with out this starchy addition, crustless vegetable quiche is a good choice.
