For our Christmas brunch, I make this variation on a classic eggs Florentine recipe, adding sausage and spinach to make a snappy casserole. Sometimes I mix in fresh peppers or green chiles, so play with it. —Karen Weekley, Washington, West Virginia

  • 1 pound bulk pork sausage
  • 2 tablespoons butter
  • 1 large onion, chopped
  • 1 cup sliced fresh mushrooms
  • 1 package (10 ounces) frozen chopped spinach, thawed and squeezed dry
  • 12 large eggs
  • 2 cups 2% milk
  • 1 cup shredded Swiss cheese
  • 1 cup shredded sharp cheddar cheese
  • 1/4 teaspoon paprika


  1. Preheat oven to 350°. In a large skillet, cook sausage over medium heat until no longer pink, 6-8 minutes, breaking into crumbles; drain and transfer to a greased 13x9-in. baking dish.
  2. In same skillet, heat butter over medium-high heat. Add onion and mushrooms; cook and stir until tender, 3-5 minutes. Stir in spinach. Spoon vegetable mixture over sausage.
  3. In a large bowl, whisk eggs and milk until blended; pour egg mixture over vegetables. Sprinkle with cheeses and paprika. Bake, uncovered, until the center is set and a thermometer inserted in center reads 165°, 30-35 minutes. Let stand 10 minutes before serving.

Eggs Florentine Casserole Tips

What is the difference between eggs Benedict and eggs Florentine?

As the most basic level, eggs Florentine contains spinach and eggs Benedict does not. Eggs Benedict, an American brunch classic, is an English muffin topped with ham and poached eggs and then finished with a rich hollandaise sauce. Many people assume that eggs Florentine is a vegetarian variation of eggs Benedict, but eggs Florentine actually predates eggs Benedict. The earliest versions of eggs Florentine used Mornay, a creamy cheese sauce that's related to béchamel (here's an overview of the classic French sauces). However, the standard modern eggs Florentine recipe is a muffin topped with sliced tomato, sautéed or steamed spinach, a poached egg and hollandaise sauce.

How long is leftover egg casserole good for?

Refrigerate any leftover egg casserole within 2 hours. You can keep an egg-based casserole in the refrigerator for up to 3 or 4 days, or in the freezer for up to 3 months. (Here's how long other foods last in the fridge.)

How do you know if an egg casserole is done?

Egg casseroles and quiches usually cook for 30 to 40 minutes and should reach an internal temperature of at least 160°. For an easy way to test for doneness, insert a knife close to the center of the casserole. If the knife comes out clean, the casserole is done.
