- Optionally, dice your green onions for garnish.
- Trim the fat off your steak and finely slice it into strips.
- In large mixing bowl combine your eggs and heavy whipping cream and fork-whisk them until frothy.
- Measure out your salt, pepper, and oil. Set aside all ingredients.
- Preheat oven to 350F.
- Heat oil in skillet on High heat for 2-5 minutes until it shimmers and pops.

Optionally, you can garnish the casserole with green onions before serving.
- Thin steaks 1/4″ to 1/2″ thick are best. Ribeye or sirloin cuts work well.

- Heavy whipping cream is typically hiding near the milk somewhere.
- Save time with pre-minced garlic and/or pre-sliced peppers and onions.
I created this recipe after seeing a viral video of philly cheesesteak lasagna and wanted to invent a low carb version.
This casserole is the first step on that mission. I started by researching these low carb philly cheesesteak casserole recipes from Grassfed Mama and Diet Doctor but they don’t hold their shape out of the pan.
So then I reviewed this keto quiche recipe from Kim at Low Carb Maven and tried to integrate some of her techniques to get my casserole to hold it’s shape.
Hope it works for you too.
