Taste my tuna casserole – tell me if I put in too much hot fudge
Woody Allen

Definitely no hot fudge in my Easiest Tuna Broccoli Casserole! But lots of veggies and a quick meal for busy days.

Cooking on a boat is definitely different from cooking on land. On our boat, the galley is small (like most boats) so one-pot recipes are favourites.

And recipes using the Instant Pot are even better like this non-hot fudge tuna casserole. It tastes just like a stove top version but takes less than 30 minutes and doesn’t use too much of my valuable kitchen real estate.

Making Broccoli Tuna Casserole on a boat

This recipe works with both dairy and non-dairy milk and cheese. I rarely have dairy milk on the boat as neither of us drink it, handsome hubby drinks his coffee black and my fridge isn’t that big.

Same with cheese. There is usually some for HH’s sandwiches and even for special meals like pizza and lasagna but I find the Daiya and Violife shredded cheddar style brands work just as well in casseroles like this.

So use what you like and what you have.

I use either Daiya or Violife shredded cheddar style for the non-dairy cheese and whatever non-dairy milk I have on hand (make sure it’s unflavoured).
