    I'm amazed at how delicious this very simple recipe came out. I'll use this practically instant sauce on other things as well.

    Can you use frozen broccoli?

    Hi Julie!

    Yes, you can! Frozen vegetables tend to release water, but this will evaporate while frying. Good luck!

    I don't use as much thyme as they say cause it will over power the whole meal if you aren't careful. I usually cut it in half and then it isn't as over powering and it still taste great

    I wasn't expecting the flavor to be this good! Delicious and easy to make! I will be making again! :)

    Does this have a breakdown of how many carbs fats and protein?

    Hi Michael!

    If you hover your mouse over the symbol for "Strict/Moderate/Liberal Low Carb" on the pictures for all our recipes then you will get the nutritional facts.

    The amount of displayed carbs is net carbs (Total amount of carbs - fiber).

    So you fry the broccoli and cauliflower from raw?

    Can I substitute the leeks for something else?

    Trying to get more information, I accidentally "reported" a couple of comments. Sorry about that. I was simply trying to found out how long the vegetables should be fried.

    Hi, would the brocolli and cauliflower not be hard if your only frying it?
    Thanks

    Is ground sausage ok to use with this recipe?
  14. P & B
    This was absolutely delicious!!! We will make this again and again! Added mushrooms, spinach and no salt or pepper (because the sausages were well seasoned). YUM! Thank you!

    I used red pesto with soured cream instead of mustard, and added left over veg like greens, peppers and garlic. I also crushed a poppadom on top (as they are low in carbs) before I added the cheese to give it a little bit of a crunch, it was delicious and really filling.
  16. Samantha
    My sour cream always cuddles when I make this. Even when baking in the oven at 400 instead of 450. Is the temperature still too high? I'm still not quite used to cooking with so much dairy. Still tasty though!

    This is great but why 16 grams of carbs nothing in it has many

    How long do you fry the sausage and the veg for? Doesn't specify. Thanks!

    Probably from the broccoli and cauliflower. I haven't plugged it into my tracking app yet, but I bet the NET carbs are much lower.

    This is definitely one of my favorite recipes. Everybody likes it. I took it over to my neighbor's last week for a potluck meal and they loved it. I don't always add sausage and then I can eat it as a side with a bit of meat.

    Recipe is great, just made it and it looks good. What is the total calorie, trying to add it in my fitness pal

    Did you ever figure it out? I add food to my fitbit dashboard.

    I definitely agree with the above that the thyme is too much. I'd actually go without it to be honest.

    side note: Recipes aren't detailed enough on this site for people new to cooking.

    I'm not sure what the reason was but I think that thanks to my "baking dish" and setting it to the top rack for 15 minutes, everything on top formed into a brown burnt crust. The amount of burnt thyme is all I can focus on on every bite.

    Just had this for dinner here in new zealand, and it was very yummy! Great, simple recipe - a lovely comfort food on a wintery night!

    I just started Keto not to long ago and getting used to knowing what I'm supposed to eat and cook. This dish is ABSOLUTELY delicious. I never knew I liked Cauliflower or Leeks before.

    Amazing recipe! It’s a keeper! Sour cream makes it really tasty!!!
  29. Beth
    I’ve made this yummy recipe several times now and it truly is super easy. I now just eyeball the ingredients because it’s very forgiving. I’ve cooked it in many different type dishes, used varying amounts of the ingredients that I’ve had on hand and it still turn out tasty! Give this one a try, you won’t be disappointed!

    Beth,
    Have you had any issues with the sour cream curdling?

    It is the onion. A medium onion about 2 - 2 1/2" in diameter has about 10g of carbs in it.

    To people saying they didn't like these veggies before, that's because our mothers steamed those veggies. Roast or fry just about anything and it tastes 408234708537029 times better. This was great, I loved it. I needed more carbs and added some spinach and a few cherry tomatoes in the last few minutes of the veggies frying. I used andouille sausage and added butter to that same pan to fry the veggies, it gave them more flavor. It's not really gratin, there isn't enough cheese for that. The sour cream dijon mix wasn't pourable, idk what's up with that part of the recipe. I just spooned it in dollops, and it cooked to a terrible curdled sour cream texture. But the taste was decent so this is staying in rotation. When I go into deep ketosis I'll probably rewrite this recipe with like four times the amount of cheese, cream, and ground mustard. Also! USE! GRUYERE! It's basic gratin cheese, way better than chedder or jack or any other pre-shredded cheese.

    I’ve never eaten sausage. So, what kind of sausage or brand is it good to get for the recipe? I want to try this recipe
  35. Beth
    Crystal, no issues with curdling but it may be because I’m adding the sauce to the frying pan with the veggies and sausage and mixing well on low to get it all mixed together smoothly before I put it in a dish to bake.
