I am a huge believer in all-day breakfast. I love pancakes for dinner. I love quiche for lunch. I will happily eat bacon and eggs regardless of the time of day. I. Love. Breakfast food. Like this Spinach and Bacon Frittata. In the immortal words of Ron Swanson…
One of the things I love about breakfast food is it’s a great way to use up stuff in your fridge. Have some leftover baked potatoes? Yes. Half a pack of bacon? Absolutely. That weird cheese you got last time you went to Whole Foods before you remembered that you don’t eat weird cheese? Throw it in there. The more the merrier.
So when I found myself with a pack of gruyere, some bacon that was not long for this world, and spinach that was two days from not fulfilling the measure of its creation, I started whipping things together. And it was freaking delicious. My kids said they liked it even better than these bacon egg and cheese cups, which is high praise coming from them.
How to make the spinach and bacon frittata
You’ll need a dozen eggs, heavy cream, 10 ounces baby spinach, organic apple cider vinegar (like Bragg’s), coarse grain mustard, salt, pepper, onion powder, and green onions, plus 6 ounces of shredded gruyere and 6 ounces of mozzarella cheese.
Yes, I did that cool thing where I left out like half of the ingredients from the ingredients picture. It’s fine, we’re all fine here.
In a heavy skillet, cook the bacon over medium heat until crisp. Remove with a slotted spoon and drain on a paper towel. Set aside.
Preheat oven to 425 F. Grease a 11-12″ oven-safe skillet or pie plate and set aside.
In the pan drippings, sauté the spinach until almost wilted. Add the minced garlic and cook 30-60 seconds longer over medium-low heat until fragrant. Remove from heat and add the vinegar mixture. Stir until combined.
While the bacon is cooking, combine the apple cider vinegar and mustard in a small bowl and set aside. Crack the eggs into the jar of a blender and add the salt, pepper, onion powder, and heavy cream. Pulse until combined and set aside.
When the spinach is done cooking, transfer to the prepared pan. Sprinkle with the drained bacon, making sure the ingredients are evenly distributed.
Sprinkle evenly with both cheeses and then the chopped green onions.
Pour the egg mixture over the bacon and spinach mixture.
Bake for 25-30 minutes or until puffed and lightly golden on top and it doesn’t jiggle in the center when shaken. Remove from the oven and allow it to cool 10-15 minutes before cutting into wedges.
