When you are making this recipe, you’ll want to use the full recipe at the bottom of the page.

1. TOAST: Evenly toast English muffin pieces and spread half in the bottom of a greased 9×13 baking dish.
2. SPRINKLE: Add half of the ham, cheese, and top with the remaining English muffin pieces.
3. WHISK: Combine eggs, half and half, and seasonings and pour over the ham mixture: use gentle presses to soak the bread.
4. LAYER: Add the rest of the ham and cheeses over the breakfast casserole, cover tightly with plastic wrap, and refrigerate for 2 hours or overnight.
5. BAKE: Take the English muffin egg bake out of the fridge and drizzle with melted butter. Place in preheated oven until golden brown.
6. SERVE: Remove from oven and let it sit for 10-15 minutes* before serving. Sprinkle with desired garnish and “B-line” to the table!

*Note: While the egg casserole sits, it continues to cook due to residual heat. If needed, loosen the English muffin bake from the edges and cut portions to decrease the heat. Consider plating slices if they are already easy to remove.

Make Ahead English Muffin Casserole Recipe Notes & Tips

• Be sure to read through the entire recipe before starting.
• The English muffins are toasted in the oven for the prep, and the breakfast casserole is baked the next day.
• Baking pre-cubed pieces allow more surface to be toasted; you can use a toaster oven or the air-fryer setting.
• Drizzling butter over the egg casserole before baking helps complete the breakfast sandwich flavors.
• If you prefer to use bacon or another breakfast meat, it should be pre-cooked, then incorporated into the overnight English muffin casserole. 
• For a smoother, creamier melt and consistency, shred a block of cheese instead of a pre-shred,
• You’ll want the semi-soft (young) Gruyere, not aged (hardened), for superior melting.
• It is easier to shred cold cheese, especially on a box grater or food processor, and avoid a “crumbled” or oily texture.

Serving Suggestions

• This breakfast casserole is delicious served with a Hollandaise sauce, asparagus, and fresh fruit.
• Go Southern and enjoy this egg bake with pickled beats, a side of cottage cheese, and pineapple
