How to make this tuna penne gratin in creamy pink sauce
- Cook the pasta: In a large pot, cook according to package instructions until al dente. Drain and transfer to a large casserole dish.
- Prepare the pink sauce: In a small bowl, mix all the sauce ingredients until smooth and well combined.
- Prep the filling: Chop the spinach and drain the tuna thoroughly.
- Layer the casserole: Spread the spinach and tuna evenly between the cooked pasta layers. Pour the pink sauce over the top and mix gently so it coats everything.

There is something quite satisfying about digging into a tuna casserole. This tuna and pasta gratin is adapted from the French gratin dauphinois to make a delicious tuna penne gratin covered with lovely gooey cheeses.
It is a simple and satisfying pasta dish, and a great way to use up some leftover tuna in your fridge or some canned tuna you have in your pantry.

The key is the sauce, which is a pink sauce made from combining crème fraiche (or heavy cream) with a ton of herbs and spices to infuse throughout the gratin.
Once the sauce is mixed, it is time to assemble the rest of the dish. Just combine the tuna with fresh spinach, pasta al denté and cheese and you are more or less done.




With that, you’ve got a hearty dish that makes a wonderful weeknight dinner, or a simple side dish for a party with friends and family.

What to serve with it?

What drinks to serve with it?
For drinks, try a light white wine such as a Côtes de Provence or a Languedoc-Roussillon wine along with the tuna penne gratin.
If you don’t like white wine, try a chilled rosé from the Rhone or Corsica.

How to store it?
If you do want to prepare this tuna penne gratin in advance, let it cool completely and place it in an airtight glass container.
However, it is not a dish that freezes very well because the pasta and cheese can get soggy, so I don’t recommend it.
