Simple Ingredients for Breakfast Eggs Benedict Casserole

What’s great about this casserole? You probably already have most of the ingredients in your fridge or pantry. Here are the stars of the show:

• English Muffins: These soak up the egg mixture perfectly while adding a slight chewiness. Regular or whole-wheat work equally well.
• Smoked Sausage: I love using beef smoked sausage for its deep, smoky flavor. Turkey or chicken sausage makes a great lighter option.
• Hollandaise Sauce Mix: The shortcut hero here—no need to fuss with egg yolks and butter. Just whisk and heat!
• Green Onions: Add fresh, mild onion flavor that pairs beautifully with the rich eggy base.

Substitutions: No English muffins? Sturdy bread like sourdough or baguette works too, just cut into 1/2-inch cubes.
