Adult Tuna Casserole

Adult Tuna Casserole at oldfatguy.ca

OK, I admit it. I like the old fashioned canned soup versions of casseroles (see Tuna Bake). However, that doesn’t mean I won’t kick up my game a bit and make a casserole that has more refined flavours and textures, for example, Adult Tuna Casserole.

I made this with Swiss instead of cheddar because I think it makes a better match to the creamy texture of this casserole. You could use cheddar, gouda, gruyere, fontina or any other cheese you like.

I started by cutting my vegetables and grating my cheese.

I heated the oil and sauteed the onions until they were soft. Then I added the mushrooms and sauteed until they gave off most of their liquid, about 3 minutes.

I added the butter and stirred until it melted. Then I added the flour and stirred until it was mixed with the melted butter.

I slowly poured in the milk and stirred until the sauce started to thicken. Then I added 375 ml (1 1/2 cups) of the cheese and dill. When the cheese is melted and incorporated, take it off the heat.

I sprayed my casserole dish with baking spray. I put 1/2 the rice in the casserole. I added the one can of the tuna and 1/2 of the green beans. I put 1/2 of the mushroom/cheese sauce over that and then 1/2 of the remaining cheese.

We served it with Broccoli Salad.

The Verdict

This casserole has a nice creamy texture from using rice instead of noodles. The texture is reminiscent of risotto. The Swiss cheese adds to that creaminess and gives a deep rich flavour. The flavours aren’t strong enough to scare kids off but do lean more toward sophisticated adult tastes. Spoil yourself. Make an adult casserole.
