Ingredient List & Substitutions

This easy egg bake is made from scratch and loaded with sausage, biscuits, and tots. Many of the ingredients needed can be substituted, read below to find substitutions if available:

• Whole eggs: I like fresh pasture raised farm eggs if available, but any kind will work for this egg bake. Liquid eggs can be used if needed. Whole eggs are recommended, using just egg whites or egg yolks will change the consistency.
• Sausage: use raw pork sausage and cook up the crumbles yourself or buy pre-cooked sausage crumbles from the store.
• Biscuits: canned refrigerated biscuits are used in this recipe, this uses 5 biscuits – we do not need to use the whole can. They make small cans with just 5 biscuits if you do not want leftover biscuit dough. Whole biscuits are chopped into 8 pieces and scattered on the bottom of the dish, I like the flaky layers biscuits. Buttermilk biscuits are great also, don’t use pre-baked biscuits.
• Milk: I recommend using whole milk here, it is thick but not overly rich like heavy cream. Low-fat milk or half and half will also work. Skim milk will work in a pinch.
• Shredded Cheese: this recipe uses shredded pepper jack cheese. You could substitute shredded cheddar cheese, sharp cheddar cheese, Colby jack cheese, or Monterey jack cheese.
• Tater tots: use frozen store-bought tater tots, they do not need to be thawed before cooking. Hash browns or diced potatoes also work.

Recipe FAQs

Why cover the egg casserole while cooking?

Covering the eggs while baking traps steam and helps everything to cook faster, it’s also helps to stop the top from overcooking or over browning before the inside is cooked through. If desired, uncover during the last 5 minutes of cooking so the top get deep golden brown and the cheese gets extra gooey!

How do you know when your egg bake is done cooking?

The egg bake is done cooking once the edges of the casserole are set and the inside doesnt look runny, the casserole will have a slight jiggle. A thermometer can also be used to test the doneness.

Can I make this casserole overnight?

Yes. Make the egg casserole through step 4, then cover with aluminum foil and refrigerate overnight. Remove from the fridge and bake covered, according to the directions, adding a few additional minutes to the baking time.
