Ingredient Notes & Substitutions
The full list of ingredients to make this easy breakfast bake is above. Below are notes about some of the ingredients along with ideas for substitutes.
Whole Wheat Flour. The whole wheat flour in this recipe adds a little bit of texture to the breakfast pie. It can be substituted with an equal amount of white flour or Bisquick.
Milk. I like to use whole milk which can be substituted with dairy-free milk such as almond, coconut, or oat milk.
Vegetables. This is a very versatile recipe. You can use any kind of vegetables that have on hand. It's an easy way to use up leftover cooked veggies; great for cleaning out the fridge!
For this recipe, I used fresh broccoli, small bell pepper, and mushrooms.
Cheese. Any type of cheese works in this recipe. We like cheddar cheese, swiss cheese, feta cheese or goat cheese.
This is an easy recipe to start preparing ahead of time. You can chop, cook the vegetables and shred the cheese ahead of time. Store the prepared ingredients in separate containers in the refrigerator for up to three days.
To assemble the breakfast pie just before serving, place the vegetables into a prepared pie plate or skillet and top them with shredded cheese. Mix up the eggs and flour as instructed in the recipe and bake.
Storing and Using Leftovers
As with many casseroles, this one tastes better after a day, so be sure to make extra. Leftovers can be stored in the refrigerator or freezer.
Refrigerate leftovers in an airtight container for up to four days.
Freeze Impossible breakfast pie once it has cooled to room temperature in a freezer-safe container for up to three months. Defrost the leftovers in the refrigerator overnight.
Reheat your veggie egg breakfast casserole in the oven at 350 or in the microwave.
TIP! Cut the leftover casserole into single servings before freezing and remove the single servings from the freezer as you need them.
Egg casseroles are so versatile and there are so many to change them up. Here are a few suggestions:
Mexican Impossible Pie. Use diced bell pepper, poblano pepper, tomato, and zucchini for the vegetables. Add ¼ to ½ teaspoon chili powder to the batter. Serve it with a side of your favorite salsa.
Breakfast Impossible Pie with Meat. Add ¼ pound of cooked breakfast sausage crumbles, cooked ground beef or a few pieces of crumbled bacon to the casserole.
Dairy-Free Impossible Breakfast Pie. Use non-dairy milk, and leave the cheese out or add a tablespoon or two of nutritional yeast to the batter for a cheesy flavor.

If you don't have a 9 or 10-inch cast-iron skillet, you can use a heavy oven-proof skillet or a 9-inch pie plate to bake this recipe. You will still need a skillet to saute the vegetables.
Yes, you can use an equal amount of frozen vegetables, but cook them first and drain all of the moisture out of them.
