I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Did you use breakfast sausages?  Mine are larger and are no way cooked enough at 400 degrees at 25 minutes.  I have a meat thermometer to check the temp.

Hi Mona, I think the best way would be to precook the sausages on a greased pan before adding them to the tray - this way you will ensure they get cooked through properly.

Have you ever “made ahead”? Time and temp to reheat? Any suggestions are appreciated!

Hi Valerie, I did! I haven't tried freezing this but I did keep it in the fridge for about 5 days. You could reheat in a microwave, in the oven, or even on the stove although that would have to be on a low temperature and stirring frequently - maybe adding a dash of water would help here.

So what do you do with the chicken stock?

Thanks for spotting that - it's added in step 3 😊

Love this recipe. Just wondering if you have tried it in an instant pot? If so how did you modified the recipe to work for it.

Thank you so much! I was wondering the same and I don't see a reason why not. I have tried it in a slow cooker though and the sausages were amazing - so soft and flavourful! I didn't change the recipe but you could skip the water/chicken stock (slow cooker).

This is definitely one of my top ten recipes. I had it without the mustard... because I started eating it so fast... then had to have another half a link after remembering (and it was AMAZING)! Thanks so much for sharing..!

Thank you so much, you are very kind!!

I always thought heat kills the benefits of enzymes and probiotics.  I love sauerkraut so would save the sauerkraut to add just before serving.

I love the flavour sauerkraut gives the casserole so I'd still use it. You could always add more sauerkraut before serving 😊

In the comments it show you can also prepare this recipe in a slow cooker, any tips on doing this? Thanks!

Hi Margie, I did try this in a slow cooker 😊 I followed the recipe until step 3 and then put everything in a slow cooker, plus topped with browned sausages. Then I cooked it for 2-3 hours on high.

I have made this several times and we live it.  I do use butter infused olive oil and do not use the chicken broth, just the liquid from the can of SK and about 2 tbsp of cidar vinegar.  Add some brown mustard and it is one of our fall favorites.  Thanks!

Thank you for your kind words, I'm glad it's your favororite!

Bloody gorgeous. I did a similar sausage and cabbage thing last week but the sauerkraut made it sing. OH hates skt but really enjoyed this. Thank you!

Modified the recipe a little to cook in slow cooker. Turned out amazing. Thank you so much.

Yes, definitely great for a slow cooker (no chicken stock needed)! 😊

Just made this and it's really good.  Will definitely add this to my menu.  I halved the recipe and cut my sausage into one inch pieces and mixed it in before baking in a 8x11 dish.  To me this had a milder taste than just putting kraut in a pot with the sausage stovetop style.  Very filling!

Thank you for your kind words, Lesa!

Looks fantastic if some lowcarb biscuits are served with it!

Absolutely, this will go great with low-carb biscuits! Here's a good recipe: Keto Cheddar Dill Biscuits
