Eggs – for heathier egg options, try egg whites or egg substitutes. You can also fry or scramble the eggs to suit anyone’s preference!
Bacon – sticking with the healthy angle, you can always use turkey bacon or veggie bacon options from your favorite grocer in place of the real deal!
Lettuce – if you really want to get the L into this dish beyond that luscious gravy, then shred up some lettuce and spread it on top after the dish is cooked for that real BLT experience!
Cheese – even though we stuck with mostly cheddar for this example, feel free to use any kind of cheese that you love. Colby Jack, Mozarella and Swiss cheeses work great as well!

Notes

** Pro Tip**

This is a great assemble ahead and bake later recipe. It also makes a great food gift! Assemble and give instructions on heating for 10 minutes at 325° to melt and combine!

🍴 PRO TIP!

Crack the eggs with the edge of the spoon while over the skillet to keep the broken shell area on top, allowing the egg to drop out cleanly into the pan. You can also spoon a little butter over the top to get things more brown around the edges and a little more done in the oven–or just flip them in the skillet!

🗹 RECIPE FAQ’S

How do I know when my roux is ready?

Once the roux becomes a paste, and when you can no longer smell the flour, and only smell the butter, you’ll be ready to add in your whole milk, pepper and salt to whisk until thick to make that magical gravy.

How do I get my gravy thick?

Cook your gravy less than a minute in the skillet to get it nice and thick. You can do a spoon test to check the thickness. Get some gravy on the back of the spoon, run your finger through it and make sure it doesn’t run from side-to-side on the spoon. This is a good opportunity for a taste test as well!

Can I make this ahead of time?

You sure can! Assemble all your ingredients according to the recipe, take it where it’s going, then heat for 10 minutes at 325° to melt and combine!
