Keto Bacon Spinach Mushroom Quiche

Our Keto Bacon Spinach Mushroom Quiche is one of Joanie’s favorite breakfast recipes. Of course, it is low carb with only 4g of net carbs per serving and the recipe is over 60% fat based. More importantly, the bacon flavor permeates every bite. The vegetables are actually cooked in bacon fat. The spinach is even wilted in bacon fat! What could be better than bacon?

We love a breakfast quiche and Joanie has a lot of crustless quiche recipes. We previously posted our Crustless Quiche with Spinach and Ricotta. That recipe is one Joanie actually makes entirely in one skillet. The vegetables are not pre-cooked. It also features cheddar as the base cheese. Her Keto Bacon Spinach Mushroom Quiche is slightly different, but equally tasty. The type of quiche Joanie creates for breakfast is often dependent upon what we have in the fridge or pantry.


This recipe is all about the bacon! Seven full slices – cooked to the perfect crispness on the stovetop, and then baked into the quiche mixture. The mushrooms, onions, and spinach are even cooked in bacon fat! With all that bacon and the added parmesan, there is no need to add salt. Joanie does add pepper, and some of you may want to add some salt to your taste. I also like the idea of a little drizzle of truffle oil as a garnish. We have previously posted our Sausage Mushroom and Pepper Breakfast Bake and talked about how well truffle oil tastes on egg dishes.

We often use ricotta and cheddar in a baked quiche or frittata. However, the pantry/fridge dictated cream cheese and parmesan for this recipe. Joanie is so used to creating low-carb recipes that use whatever is available – the taste is always unique and delicious. This one is no exception! We also love fresh baby spinach in any quiche, omelette, or frittata.

Preparation Tips

Make sure that you cut your cooked bacon slices into small 1/2 inch pieces. The key tip is to keep the bacon fat! Yes, good old fashioned bacon fat to cook the onion and mushrooms. It will even wilt the spinach. The bacon flavor will be in every bite! You do not really have to cook the mushrooms and onions very long since they will soften when baked with the egg mixture. Just keep that bacon fat!

Joanie often finds that she will have extra batter when making her quiche recipes. She usually uses a tart sized baking dish, often 9 to 10 inches, instead of a traditional pie dish. Since the recipe will fill a standard pie baking dish, the quiche in a tart dish will not be as high. Left over batter is the result. Rather than cut down the size of the batter Joanie usually uses a few ramekins, so we have individual muffin-size mini quiches. She likes using heart shaped ramekins – that is what you see shown in the pictures above. If you prefer a taller quiche slice, same recipe, just use a traditional pie baking dish.
