Bisquick Impossible Tuna Pie

If you’ve never made an Impossible Pie, this is kitchen magic at its best. Bisquick, eggs, and milk go into the blender, then pour over a layer of tuna, cheese, and pimientos in the pan. As it bakes, the baking mix settles to the bottom and forms a crust while the egg-milk mixture sets into a savory custard on top.

This is genuine 1970s test kitchen genius. No rolling, no chilling, no fussing with a separate crust. One blender, one pie plate, one pan in the oven.

Sharp American cheese is the unsung hero. It melts smoother than aged cheddar, holds its color, and brings the salty-savory depth that balances the mild tuna. The pinch of nutmeg in the custard sounds odd until you taste it, then it makes sense, the same trick used in classic quiche Lorraine.

Pimientos add color and a slight sweet-pepper note that brightens the whole pie. Sliced tomatoes on the side cut through the richness for a complete plate.

Pro Tips

• Drain the tuna thoroughly, excess moisture waters down the custard and makes the bottom crust soggy
• Blend the milk, eggs, biscuit mix, salt, and nutmeg in a real blender if you can, hand-beating leaves lumps that sink unevenly
• Test for doneness with a knife between the center and edge, not in the middle, the very center stays slightly jiggly until cooled
• Let the pie cool the full five minutes before slicing so the custard sets cleanly

Variations

• Swap canned tuna for canned salmon or flaked cooked chicken for a different protein
• Stir in a handful of chopped cooked broccoli or sauteed spinach for extra vegetables
• Use shredded sharp cheddar or Swiss instead of American for a sharper, more complex flavor
