Low Carb Broccoli Tuna Casserole Bake

 

Low Carb Broccoli Tuna Casserole Bake

This Low Carb Broccoli Tuna Casserole Bake is a special request for my dad. He loves tuna casseroles and is really trying to eat healthier these days along with our whole family. I made a similar recipe for Thanksgiving that was just a broccoli casserole. This adds in some great protein from the tuna (or salmon) to get good Omega-3 fatty acids into your diet.

I love broccoli. I love it in casseroles, in stir-fries, and as a simple side dish. Broccoli is so healthy for your too, full of vitamins and minerals.

I’m also a new fan of cauliflower. We eat it if not every night now, every other night. It is so flexible and can become anything you want it to be. Did you know you can even make a pizza crust from a cauliflower? I know… It is pretty amazing.

This is a pretty easy throw together meal too. Mix everything in a bowl and just spread it over your broccoli and cauliflower. Top with cheese, because cheese makes everything better. I shred my cheese in my  Food Processor. It saves me money and I don’t get the filler ingredients added.

  1. Angela, this looks SO good! I am also a recent convert to cauliflower (it was the cauliflower pizza crust that has been making the rounds in blogland that convinced me). So excited to try this recipe because it has broccoli too!

    • Yum! I love cauliflower pizza… so so yummy. My daughter is all about broccoli right now (she’s 3 so anything to get her to eat her vegetables is a double plus). I loved how easy this was to make too. Thanks for leaving me a message!

  2. Oh that looks good! Do you think I could just sub more mayo in place of the cream cheese? We don’t eat any dairy. I can easily leave the cheese of the top, but I’ll have to sub the cream cheese with something. Anyway, I will definitely try something because this looks great. 🙂

  3. Looks like a easy healthy recipe for a one dish meal. Thanks for sharing on Real Food Friday Blog Hop. Always love your recipe Angela. Have a wonderful healthy day!

  4. This sounds like a yummy way to have a tuna casserole. We’re big fans of casseroles, too because they’re easy to make and can feed a lot of people.

    Thanks for linking up at the Pinterest Foodie Party!

  5. It looks so yummy and makes me very hungry right now. It is very healthy as well. Thank you for sharing.

  6. YUMMY! I’m sending this to Dad. He has diabetes and is always looking for low carb or carb free dishes. Thank you for linking up with the Wake Up Wednesday Linky! Stop back next week to see if you’re featured.

    • My dad loves tuna.. haha. So this was a winner for him : ) I love that eating low carb doesn’t have to be boring grilled chicken salads. Thanks for your comment!

  7. I have also made this substituting canned chicken. The flavor is just as tasty. Thank you for this quick weeknight dinner.

  8. This was a GINORMOUS hit tonight! All three kids and my husband asked for seconds. I used fresh broccoli and cauliflower and this meal could not have been easier or quicker to put together! Thank you for a delicous, easy, and fantastic recipe!!

  9. Heeey 🙂 I love this recipie 🙂 do you think i could replace the cream cheese with sour cream?

  10. Do you the nutritional for this dis? Well mainly want to know how menu carbs are in this dish… Looks yummy!!

  11. Do you have any ideas on the nutritional values of the ingredients ?
    I log all of my meals, and try to keep below 60 Carbs per meal. Also,
    what are we talking here on serving size ? It sounds yummy …….
    Can’t wait to try it! Thanks for posting the recipe. Sorry I didn’t catch
    the other requests for the nutritional values, but I did not see an answer
    to the questions. Maybe it was sent privately ? If so, could you please
    clue me in on what they are ?

    Thanks Stella

  12. Posting here because this is now a go to recipe for me, I actually have my latest in the oven right now. Thanks so much for posting this!!! Such a great regular low carb meal. I have put my own personal touches on this:

    1) I use an onion and herb seasoning instead of celery seed, haven’t got around to picking up that particular seasoning
    2) I use about double the garlic, sometimes I use fresh instead of powder (I love garlic)
    3) I use heavy whipping cream instead of mayo (never been a big mayo fan)
    4) I love my vegetables, so I usually roughly chop 3-4 different types of vegetables that go well with the other ingredients and throw them into the food processor, pulverizing them with whipping cream before mixing with the tuna/salmon and cream cheese. Tonight I used leftover pieces of eggplant, celery, red onion and green capsicum. Previously I’ve also used mushroom and zucchini, whatever veg I have around usually. I’ve never had a bad result doing this. Though it can be a bit of a balancing act getting all the ingredients not to spill over the top of the casserole dish, I just poke the broccoli and cauliflower until enough of the mixture seeps through to make room for all of it.

    Thanks again for sharing!

  13. I tried this tonight and was BLOWN away!!!! I didn’t have quite enough cream cheese, maybe 6 ounces, and I also used mixed broccoli, cauliflower, carrots and zucchini! But, all the rest was exactly as written!
    I ABSOLUTELY LOVE IT! I wanted to eat the whole thing myself, but had to share with my husband….who also wanted to eat the whole thing! hahahaha Thank you so much! DELISH!!!!!

  14. This casserole is so delicious! I make it all the time– it’s great with even chicken or another type of fish. It’s a great way to eat more greens as well. If you’re low carb, do yourself a favour and try this recipe!

  15. I’d really like to make this and am wondering how leftovers would freeze….? I live solo and while I’m sure I could cut the recipe in half, it’s also great to have things waiting in the freezer for nights I don’t want to cook.

    Thanks!

  16. Would you please email me how many net carbs per serving for this tuna broccoli casserole. It sounds so good. I can’t wait to make it. Thank you.

    • Hi Lorie!

      I haven’t done the calculations on this specifically (or I would be happy to send it to you!). If you are able to come up with it when you try I’d love to see what you arrive at!

      Hope you enjoy it!

  17. All that cheese—-hard to imagine this is low carb; please add nutritional analysis. Sounds yummy;but I REALLY have to know carb count and serving size.
    Thank you

    • Hey Robin!

      I haven’t done a full analysis of the dish (though if you end up trying it I’d love to see your numbers!).

      2 Cups of Shredded Cheddar Cheese is less than 3 Grams so that’s the whole dish. Obviously there is some fat content in the cheese but the carb value is quite low. You could also cut down on the amount of cheese if you wanted to further lower the fat content (it’s just for topping so it’s up to you on how heavy you go).

      I hope you give it a try and it works out for you! 🙂
