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 dish, and a great way to use up some leftover tuna in your fridge or some canned tuna you have in your pantry.

ingredients for the pink sauce
Making the pink sauce

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.

Frequently asked questions

What to serve with it?

cutlery

This tuna penne gratin would go well with a starter like bruschetta or a tomato tartare. Another option would be a salad like this Périgord salad with gizzards.

What drinks to serve with it?

two wine glasses

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.

freezer

Can you prepare it in advance?

Yes, 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.
