Cheesy tomato and tuna pie



I’m a big fan of gluten free Bisquick, and impossible pies.  They are easy to make and really delicious.  This one knocks it out of the ballpark.

It’s really easy to put together.  Having farm fresh tomatoes doesn’t hurt either, but the supermarket variety will do.  You can find the original Betty Crocker recipe here.


1 9 oz can tuna in water, drained
1 small onion, diced
1 package dairy free shredded cheese
1 tablespoon dairy free spread
1/2 cup gluten free Bisquick
1 cup dairy free milk
2 eggs
salt and pepper to taste
1 teaspoon Mrs. Dash original
1 tablespoon mayonnaise
1 large, ripe tomato, thinly sliced


Spray a 9 or 10-inch pie plate with cooking spray.  Preheat oven to 400 degrees.
In a covered microwave-safe bowl, cook onion and dairy free spread on high for 30 seconds to one minute, until onion is soft.

Drain tuna and put into a small bowl. Add Mrs. Dash seasoning, salt, pepper and 1 tablespoon mayonnaise. Stir in cooked onion and melted spread. Turn mixture into the greased pie plate. Sprinkle with half of the cheese.

In a small bowl, whisk together Bisquick, milk and eggs, until combined. Pour over tuna mixture. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. A few moist crumbs are ok.

While pie is baking, slice the tomato into thin slices.

Remove pie from oven.

Sprinkle remaining cheese over the top of the pie. Lay slices of tomato evenly over the top of the cheese.

Turn on oven broiler. Place pie under broiler until cheese is melted.

Let cool five minutes before serving.


  • Microwaving the onions will save you from using a frying pan just for that purpose.
  • I used Mrs. Dash and mayonnaise to spice up the tuna a bit, and give it moisture.  You can put plain tuna in the pie if you wish.
  • I used the same bowl for mixing the tuna, and then the Bisquick mixture, thus saving another dirty dish.
  • Take your dairy free cheese out of the refrigerator at least 15 minutes before you plan to use it.   This will help it melt easier.
  • I used Daiya shreds-I’m not a big fan but it tasted ok in this pie.  I couldn’t get my usual Daiya cheddar block.
  • I used coconut milk (not coconut cream)
  • I put the cheese under the tomatoes because they look so pretty, and I like the tomato to shine.  You can put the cheese over the tomatoes if you wish.
  • I put the pie under the broiler for about 3 minutes, until the cheese melted, keeping a close eye on it.  Dairy free cheese does not melt well.  Putting it under higher heat makes this much easier but watch that it doesn’t burn!
  • The recipe calls for a 5 oz can of tuna, but I don’t think that is enough.  You can use more or less to your taste.

My husband raved about this pie.  We could have easily polished it off, it’s that good.
