Crispy-On-The-Top Tuna and Green Pea Casserole (Rocco Dispirito)

Total Time

This recipe is based on one of Rocco Dispirito’s from his book, Now Eat This! Diet. He says in its intro, “Who grew up eating tuna casserole? Raise your hands. That’s just about everybody. Okay, this is not your mother’s tuna casserole…nor does it use Tuna Helper. But it does taste just as wonderful – without losing any of its comfort-food flavor. I’ve wowed it up a bit with Dijon mustard, and I used whole wheat panko bread crumbs for that traditional crunchy topping. If you can’t find these particular bread crumbs, you can always toast leftover whole wheat bread and break it into crumbs with a rolling pin.” I made this the other night with French’s French Fried Onions because I was out of panko bread crumbs. We loved this dish and it has become a new staple dish for us.

*Made for Australia/NZ Swap #55* I should have realized from the ingredients that this would be very mild. I prepared this according to directions with the exception of subbing artisan Taco cheese blend for cheddar. Not too flavorful the first night, but made a large quantity for 2. Tonight. I took 1/2 of the leftovers and added 3 Tbsp. melted butter with 2 tsp. crushed garlic and 1/2 T. seasoned salt, and covered with shredded extra sharp cheddar, and warmed in a 350* oven for 20 minutes. MUCH more flavor ! Will add same to the last for another night. Thanks for posting, Mersaydees.

This was a simple, lower calorie casserole to put together. I only used 10 ounces of tuna and increased the pasta to the full 12 ounce box. So my casserole was not as creamy but still very tasty. Made for Please Review My Recipe 2012

I loved this take on tuna casserole! You couldn't tell it was made with lighter ingredients at all. I liked the tang from the dijon mustard, but my husband didn't care for that as much. I wouldn't change a thing about this except maybe just leave the breadcrumbs off next time. Thanks for posting! Made for Photo Tag.
