  • Heat butter in a skillet over medium heat and stir in onion. Pour in red wine to cover the bottom of the pan and sprinkle with sugar. Cook and stir until onions are tender and translucent, 10 to 15 minutes.

  • Combine heavy cream, mozzarella cheese, cayenne pepper, salt, and black pepper in a bowl. Stir into onion mixture.

  • Cut pie crusts into 3-inch circles using a cookie cutter. Place circles into the bottom of 12 muffin cups in a muffin tin.

  • Spoon onion mixture evenly on top of the tart crusts.

  • Bake in the preheated oven until a toothpick inserted into the centers comes out clean, about 20 minutes. Let cool 10 minutes before popping tartlets out of the muffin tin.

Cook's Note:

This recipe makes 12 large tartlets using a standard muffin tin, or 24 small tartlets using a mini muffin tin.

6.14.20 Admittedly, this was a Sunday lunch indulgence. I followed this recipe to the letter with the exception of substituting Gruyere (would use again) for the mozzarella (none on hand). The only negative I have is that I think there’s waaaay too much butter in this recipe. After I filled the tartlets, butter was pooling on the top of the onions. When I took them out of the muffin tin, my fingers were coated with butter, and the bottoms of the muffin cups had a layer of butter sitting in them. Next time, I definitely will start with half the amount in the recipe, and if needed, add a bit more. On the positive, they taste absolutely divine, seriously, they’re that good. Also, very, very rich. I’ve had this recipe on my radar for quite some time, and I’m glad I finally made it. Jaime, thanks for sharing your recipe. Read More
