Advance Prep
For big pieces (over .75lb each): Prick skin all over with a push pin (this will allow the fat that is under the skin to render out when cooking). Preheat oven to 400F (smaller breasts can be finished on the stovetop)
For smaller breasts, start here: Place duck breasts to freezer for about 30 minutes, or until skin begins to firm.
Sear Slowly, and Render the Fat
Place breast, skin side down, in a cold frying pan over low-medium heat. Use an offset spatula to firmly press down on the pieces every couple of minutes. As the breast heats up, the fat will begin to render. We recommend using a splatter guard. Drain the fat every few minutes as it builds up (save the fat). After about 10-15 minutes, as fat rendering slows, skin should be nice and brown.
Finish the other side
Flip breasts. For larger breasts, transfer pan to oven and cook to medium rare (5-15 minutes, depending on the thickness of the breast). Medium rare will feel firm with just a bit of give. For smaller breasts, continue to cook in pan to medium rare.
To serve
Remove breasts from pan and let rest for about 5 minutes. Slice into 1/8” slices. Serve with a sweet fruit sauce, such as:
