Tonnato is a creamy and tangy sauce made with anchovies, capers, and canned tuna that tastes waaaaay better than it sounds. It’s a Whole30- and keto-friendly sauce that tastes delicious drizzled on veggies and roasted meat!

Okay: what do you think of tonnato? For those of you smiling—high five! And if your nose is wrinkled in anchovy-hating disgust or bafflement, hear me out. I was once in your shoes, but this umami-packed paleo sauce is truly a cinch to make from pantry staples and tastes good on EVERYTHING.

If you’ve never tried tonnato sauce, you’re in for a treat! This traditional Italian sauce is made with anchovies, capers, and canned tuna—it sounds wacky, but it tastes so dang good! Plus, this version is rich, savory, Whole30- and keto-friendly, and totally versatile!

This classic Italian sauce is typically paired with chilled poached veal (vitello tonnato) and served as a picnic dish. Sadly, I almost never have poached veal lying around the house, so after I blitz a fresh batch of tonnato, I pour it on crudités (raw vegetables), hard-boiled eggs, sliced heirloom tomatoes, cooked chicken, or steamed vegetables. Or all of the above.

You can keep the tonnato sauce in a sealed container in the fridge for up to a week. I don’t normally freeze it because the texture gets wonky when you thaw it. Just put it on all the things already!
