To make this Tuna Potato Casserole I dumped some margarine into a sauce pan over med/lo heat.

Once the margarine had melted I stirred in some Bob's Red Mill 1 to 1 Gluten Free Baking Flour.

Then I measured in some salt, garlic powder, black pepper and paprika and stirred them until they were well incorporated into the paste.

Next, I slowly poured in some almond milk while continuing to stir.

I allowed the sauce to continuing heating on the stove while I stirred it occasionally.

While the sauce was heating, I chopped up one yellow onion.

I also used my mandolin to evenly slice 3 potatoes or enough to make about 3 cups.

When the sauce had just started to boil and was thickened, I turned off the burner and greased a small casserole.  Mine was 1.8 litres.

I arranged a layer of sliced potato on the bottom of the casserole.

For the next layer I mixed the cut up onion with 3 cans of Flaked White Tuna which I had drained.  You could use 2 cans if you prefer.

I stirred the two ingredients together until they were well combined.

Once combined, I spread ½ of the mixture over top of the potatoes already in the casserole dish.

I followed this with another layer of sliced potatoes and the remaining tuna.

Then I topped the last tuna layer with the remaining potatoes.

The last step before it hit the oven was to pour the cream sauce over the last layer of potatoes.

After I finished spreading the cream sauce it was time to bake the casserole in a preheated 375F oven.

I baked the casserole for 1 hour or until the sauce was starting to brown and bubble.  You want the potatoes to be tender as well.

After removing it from the oven I served it immediately.

This tasty casserole is full of flaked tuna and potatoes.
