egg casserole

This is the basic recipe that I use to make the egg casserole we eat regularly. I call it "egg pie"! This recipe is really flexible on all of the amounts, combinations and even the cook time and temp - perfect for an easy, healthy meal! See below for tips, variations, and flavor combinations to try.

Serves 6-8

Ingredients:

  • 1 lb cooked Whiffletree sage sausage (or any other leftover cooked meat, diced or crumbled)
  • ½ c diced onion
  • ½ c diced veggies (Hard veggies like broccoli, sweet potato, or asparagus should be cooked. Soft veggies like peppers, zucchini, spinach, and squash can be raw. Spinach and zucchini are our favorites!)
  • 2 c shredded cheese (mozzerella, parmesan, and cheddar all work great!)
  • 12 eggs
  • 1 c of dairy (Milk, cream, yogurt, cottage cheese, and sour cream all work.)

Instructions:

  1. Preheat your oven to 350
  2. Put 1lb of cooked meat in the bottom of a 9x13 Pyrex dish or 12” cast iron skillet
  3. Sprinkle ½ cup of onion and ½ cup of veggies on top of the meat
  4. Sprinkle 2 cups of shredded cheese on top of the meat and veggies
  5. Whisk 12 eggs with 1 cup of dairy
  6. Pour egg/dairy mixture over the meat, veggies, and cheese
  7. Bake for about 30 minutes. The casserole should be browned and puffed on top and not jiggly in the middle

Variations/Tips:

  • Cook the meat, veggies, and eggs on the stove top as a scramble!  Sprinkle cheese and herbs on top at the end.
  • Turn up the heat as high as 425 if you are in a hurry (350 just gives the nicest texture to the eggs in my opinion).  
  • If you are in a hurry or want to use raw cheese and preserve the enzymes, you can sprinkle cheese on top after the casserole cooks.
  • Skip the dairy blended in with the eggs if you don't have any to spare!
  • Sprinkle any fresh herbs on top such as basil, parsley, oregano, or thyme
  • Add a green salad, some wholesome bread, or roasted root veggies on the side for a complete meal.
  • Don't forget the leftovers for breakfast or lunch the next day!

Flavor Combinations:

  • sage sausage, onion, zucchini, basil, parmesan shredded on top afterward
  • ground beef, onion, tomatoes (diced canned or fresh), mozzarella, basil, and oregano
  • chorizo sausage, onions, kale, sweet potatoes, cheddar, thyme
  • shredded chicken or pork, onion, broccoli, cheddar, parsley
Enjoy!
