Homemade Jalapeno Tuna Casserole Recipe
No cans of soup in this tasty homemade tuna casserole recipe! Don’t shy away from the bits of fresh jalapeno in this unique tuna casserole recipe–it isn’t spicy because the seeds and membrane is first removed. It just adds a really great flavor.
Our two boys, the youngest of whom does NOT like anything even remotely spicy, gobbled this up and had an extra serving or two besides. I think there’s a few key things to keep in mind for a really standout tuna casserole recipe: don’t skimp on quality ingredients!
Only use a high quality tuna in this recipe, preferably a tuna packed in oil, or, better yet, go with Wild Planet Foods Albacore. It seriously makes a huge, huge difference in flavor and, no, this is not a sponsored post!
The Dijon mustard is also a necessity. That yellow stuff just won’t cut it in this recipe. The mustard gets mixed into a sauce. There’s so much flavor here! I personally prefer a saucier tuna casserole so I think that next time I will double the sauce recipe to meet my tastes. If you prefer a good ratio of sauce to noodles, I would make this recipe as is. Either way, it’s fabulous.
This is not your mama’s tuna casserole. There’s plenty of basic tuna casserole recipes out there (including on this website) but for something a little different, a little out of the ordinary, definitely try this!
