Keto Tuna Broccoli Casserole
Keto tuna broccoli casserole delivers all the flavor of rich tuna casserole with only 5 net carbs per serving. Tender broccoli and delicious tuna are mixed with a rich, creamy cheese sauce, topped with a crunchy pork rind topping, and baked to golden perfection.
I love making low-carb and keto recipes for myself and my family. I don’t live a keto lifestyle, but the ingredients typically found in these dishes are some of my favorites.
Recipes like my sugar-free keto candied pecans are always a nice, sweet treat, and protein-packed recipes like my chicken broccoli alfredo casserole can be easily tweaked to make them keto-friendly, as well.
The latest addition to my lineup is this keto tuna broccoli casserole. It’s loaded with all the flavor and texture of classic tuna casserole, but I make it without noodles and add a pork rind topping for crunch.

What to Serve with Keto Tuna Broccoli Casserole
Serve this casserole with a light side salad and vinaigrette. You can also pair with more vegetables.
Tips
- Steam your broccoli until it just starts to become tender. It will continue to cook as the casserole bakes.
- White albacore tuna is flakier and has a milder flavor than chunk light, making it a good choice for this dish.
- To easily crush the pork rinds, place them in a resealable baggie and give them a few gentle whacks with a rolling pin.
- Be sure not to let your garlic brown. Browned garlic doesn’t get sweet like onions. It gets bitter.

FAQ
Cream sauces made without flavor usually use cheese to make them thicker, along with simmering them to cook off excess moisture.
To keep broccoli from getting too soft and soggy in your casserole is to undercook it a bit. It will continue to cook as your casserole bakes.
Solid white albacore is best for a casserole. It’s firmer and flakier than chunk light, giving the casserole a better texture.
