How To Make Potato Gratin Stacks

1. Preheat the oven to 395 degrees F (200 C). 
2. If making your own bacon bits, fry your bacon, pat dry of grease, and finely crumble.
3. Wash the potatoes and scrub them well. We recommend leaving the peels on for added texture, but you can peel the potatoes if you really want to.
4. Carefully slice the potatoes as thin as possible using a mandolin or chef’s knife.
5. Peel and press or grate the garlic cloves.
6. In a large mixing bowl, combine the heavy whipping cream, eggs, garlic, thyme, nutmeg, and salt. Withhold some thyme for topping.
7. Add potatoes, bacon, and 1 cup of parmesan to the bowl. Mix well.
8. Spray muffin tin with nonstick cooking spray or brush with olive oil.
9. Spoon equal portions of the potato mixture into each tin (recipe fills one standard 12-slot muffin tin).
10. Top each portion with some of the remaining parmesan and thyme.
11. Bake for 20 minutes, let cool in the tin for 5 minutes, and serve warm!

Notes And Bottom Line

From Sunday football to weekly meal prep, there are tons of ways you can utilize this low-effort potato snack. You can store them sealed in the fridge for up to a week, and reheat them however is most convenient to you — although we recommend the air fryer to crisp up the outsides.

A garlic press isn’t necessary, but if you don’t use one, be sure that the cloves are still finely minced or grated. Using coarse garlic chunks will lead to a less evenly distributed flavor in the final product.
