20 Jan 2011 Veggie Breakfast Casserole

Do you have a breakfast casserole in your repertoire?  Breakfast casseroles are great (but they don’t photograph well).  The bulk of the work is done the night before.  The casserole rests in the refrigerator while you sleep, and is taken out and baked in the morning. Breakfast casseroles are a wonderful thing if you are entertaining overnight house guests.  They are  convenient to make for groups of friends sharing a snow condo or the beach house.  They are a must for family gatherings such as Christmas morning and special occasion-baby shower, Valentine’s Day-brunches.  Breakfast casseroles are popular at potluck brunches.  You just gotta have one or two in your repertoire!

Here’s a good one to start with.  It’s based on a Spinach Strata recipe from epicurious.com, but I increased the spinach, added mushrooms, decreased the mustard and the eggs, and changed the method! I guess that means this recipe is adaptable.  Don’t like all that spinach? Use half and then add something else that you do like, diced and drained tomatoes, chopped artichoke hearts, sauteed diced zucchini, maybe?  Want to add in a ¼ cup chopped bell pepper or spicy peppers? Go ahead!  Don’t have the specific cheese mentioned? Use what you like and what you have on hand (just don’t use all cheddar or you will have a greasy mess).  Want to saute fresh spinach instead of using frozen spinach?  Go for it! You could also add some browned sausage but I really think a few slices of good bacon on the side would be better. Be sure to add some citrus on the side, too, so that all the iron from the spinach can be absorbed!

My one problem with this recipe is that it makes soooo much! Breakfast casseroles are filling, a 9 x 13 inch pan full serves a crowd of 12 or so (variable of course, depending on how many hale and hearty men and teenage boys you have in the crowd), which is good for many occasions, but not so good for a  quiet brunch at home.  If you are making this just for you and your immediate family, half the recipe and bake it in a 9 inch square pan for a bit less than the stated cooking time.  Leftovers reheat well in the microwave and I have enjoyed this for breakfast, lunch and dinner!

I think you’ll enjoy having this recipe in your repertoire.  If you get hooked on breakfast casseroles, I have a smoked salmon one to share, too 🙂

Veggie Breakfast Casserole

  • 2 (10-oz) packages frozen spinach, thawed
  • 1 lb. mushrooms, diced
  • 1 ½ cups finely chopped onion (1 large)
  • 2 tablespoons butter, divided use
  • 2 tablespoons olive oil, divided use
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon  nutmeg
  • 8 cups stale cubed (1 inch) French. Italian or Sourdough bread (1/2 lb)
  • 2 cups (about 6 oz) coarsely grated good melting cheese such as Gruyère, Jack, Smoked Gouda, Mozzarella, cheddar (the combo used will affect the taste of your casserole, of course.  For the best taste, mix your cheeses.  Definitely don’t use a full 2 cups of SMOKED Gouda (overpowering smoked taste) or cheddar (too greasy).
  • 1 cup (about 2 oz.) finely grated Parmigiano-Reggiano
  • 2  ¾ cups milk (I used 2%)
  • 8 large eggs
  • 1 tablespoon Dijon mustard
  1. Defrost spinach in the microwave and let cool.  Then squeeze–and I do mean s-q-u-e-e-e-e-z-e handfuls of spinach to remove as much liquid as possible.  At least half your “spinach” will be green water.
  2. Cook onion in 1 tablespoon butter and 1 tablespoon in a large heavy skillet over moderate heat, stirring, until soft, 4 to 5 minutes. Stir in spinach and ½ teaspoon salt, ¼ teaspoon pepper, and nutmeg.  Cook, stirring, for a minute or so and then remove from pan.  Add diced mushrooms and another tablespoonful of butter and olive oil to the pan.  Saute mushrooms until cooked, about 5 minutes.  Raise heat, and boil off excess moisture.  Add mushrooms to onion spinach mixture.
  3. Pour bread cubes into a very large bowl.  Stir in cooled spinach mixture and cheeses.
  4. In another bowl, whisk together milk, eggs, mustard, and remaining ½ teaspoon salt and ¼ teaspoon pepper.  Pour this mixture over the bread-veggie-cheese mixture in the large bowl.
  5. Pour mixture into a 9 x 13 inch pan.  Spread mixture evenly into corners and smooth the top. Chill the casserole, covered with plastic wrap, overnight (8 hours or so).
  6. Preheat oven to 350°F while casserole stands at room temperature for 30 minutes.
  7. Bake breakfast casserole, uncovered, in middle of oven until puffed, golden brown, and cooked through, 45 to 55 minutes. Let stand 5 minutes before serving. Enjoy!

Enjoy your breakfast casserole with some great coffee, sliced fruit and a slice or two of really good, salty bacon and thanks for stopping by my kitchen this fine, fine morning!
