Keto: Dairy free #6

Following a healthy dairy-free diet doesn’t have to mean depriving yourself — and this week’s meal plan is proof of that.

On the menu, we have some spice-heavy keto dishes like our Sindhi-style lamb curry. Additionally, there are some quick and easy weeknight favorites such as our tasty tuna zoodle salad and chicken stir-fry.

While following this plan, if you’re not a big fan of certain ingredients, feel free to swap them. If, for example, you don’t enjoy eating lamb, you could always substitute it for chicken or beef.

The same goes for vegetables. If there’s something you don’t fancy, change it for another low-carb veggie. Check out our visual vegetable guide for more inspiration.

Get ready to enjoy some of our favorite keto meals while staying below 20 grams of net carbs per day.

    question for anyone who's tried this already: my sweetheart doesn't like cauliflower - has anyone tried substituting any other vegetable? How did it go? Thanks so much!!!

    Zucchini,yellow squash, chayote.
    Other milder tasting vegetable from the cabbage family like chinese cabbage or bok choy, turnip or kohlrabi.

    I made this last night. The Dijon mustard overpowered the dish. It's not edible. :o(

    there are about three pounds of ingredients in this recipe. a mere tablespoon of dijon overpowered it and rendered it inedible for you? perhaps you added an incorrect amount. i thought the casserole was delicious--even my young nephews enjoyed it.

    I am not big on sauces and I do not like dijon so I used regular mustard, and only about 1/4-ish tsp of it.
    Gave a good tang to the mixture - like a burger would taste (to me).

    This is fantastic with grated zucchini (instead of cauli) and regular mustard :-D

    Love this recipe... just have 1 question, why whole tomatoes only to chop it up anyways? Why not just put chopped tomatoes on the ingredients list instead?

    My 7 year old devoured this! We chopped the cauli and he ate it no issues at all.
