I never realized how versatile canned tuna was until I started developing recipes for Genova Seafood. The extra punch of protein that is instantly added to a dish is a great bonus. Canned tuna is also a great blank slate to play around with flavors because you can literally add anything to it and the tuna will absorb up all the flavor and be so tasty!
In this spinach and tuna stuffed shells pasta casserole, I wanted to pack the shells with loads of filling — because that’s the best part of anything stuffed, right? I also wanted lots of protein because I find that sometimes pasta dishes don’t have nearly enough protein and it’s just all carbs and it doesn’t keep you full long enough. You certainly won’t be looking for more food after eating this spinach and tuna stuffed shells pasta casserole! You’ll have a happy and full belly.
I only had to use one can of tuna the Genova Yellowfin Tuna in Olive Oil because of how much is packed in there. This casserole is perfect for two people and the amount of filling to pasta ratio is just what you would expect. Not too stingy at all and thanks to the tuna, it really does fill you up! One can has 26 grams of protein! Not only that, tuna is full of vitamins and minerals and Genova’s tuna is packed in olive oil and salt — that’s it. Truly a healthy and flavorful addition to any meal!
Additionally, the tuna comes in Easy Open Cans and so while my hands were covered in spinach (from draining), I loved not having to open a drawer and reach in there to grab a can opener. I was very easily able to pop a can open and add it directly into my bowl to start building the filling for this pasta casserole!
If you take a look at the can, you’ll see a new blue label on it. That label is a certification standard and Genova’s product line recently all received Marine Stewardship Council (MSC) certified labels. MSC is the world’s leading certification standard for sustainable, wild-caught seafood. The providers of MSC-certified products must meet rigorous standards for sustainable fishing practices. I love a brand that acts responsibly!
