Whole30® Baked Eggs in Marinara Sauce
The number of servings depends on the number of ramekins you have available and the amount of space in your baking dish. I think 4 is reasonable without overcrowding. I do not know if this would work with more than one baking dish full of ramekins at a time or how this might impact overall cook time.
For less firm eggs, cook for only 15 minutes.
