I don’t make baked ham very often. I’m not really sure why. I like ham, it’s just not something that pops into my head when I’m planning my weekly shopping list. Months or even years will go by without me feeling the urge – but when I do, I normally prefer a sweet glaze on it.
In fact my favorite baked ham recipe is from Nigella Bites cookbook and it’s the coca-cola ham. You simmer it in cola and onions for a few hours, then remove it and slather it with molasses, brown sugar, cloves and mustard powder and bake for an hour until crispy and sticky. SO. GOOD. When I do make that baked ham, I always serve it with her sweet corn custard from the same book, which is also amazing.

Anyway, they were practically giving hams away at the grocery store the other day and I couldn’t pass one up. Obviously my usual preferred methods for baked ham weren’t going to work for a keto version, so I had to come up with something different. Being that the winters are mild here in SC, my rosemary bush is thriving so I picked a bunch of that and chopped it up. I love mustard with ham, so in it went along with some mayo. Then some minced garlic, and freshly ground pepper and my paste was made.
I slathered it on the smoky caramel colored skin and popped it into the oven at 300 degrees for 5 hours (for a 19lb ham). This Rosemary & Mustard Crusted Baked Ham was really, really good! Not necessarily a groundbreaking combination – but there’s something to be said for simplicity. I just may have a new favorite way to eat ham, and I have a feeling it will be making it onto our table a lot more often from now on…

The recipe cites ‘smoked ham’ but doesn’t say what size? Probably impacts the amount of ingredients for the mustard glaze, right?
Steve Kwan says
Made this for Christmas Eve. This was amazing. Thank-you for the recipe will be doing this again.
Followed the recipe implicitly. I feel I have no right to rate or comment on a recipe unless I follow the author’s instructions.

My DD was hosting Easter dinner and I helped picked out this recipe! I normally is not a fan of ham because I find it too salty, but this dish turned out excellent! I am saving this one as ham is one of my DH favorite dishes!

Kasey says
I have been searching for weeks for a not-sweet ham recipe. My husband wanted ham for Christmas but doesn’t like his meat sweet. Thank you for saving my Christmas Dinner!
Rebecca says
Hi, do you think I could use a spiral cut ham for this recipe? I would probably need to cover it or put in an oven bag to keep it from drying out, right?
Laura says
This looks delicious! It’s there a suitable replacement for the mayo?
Vanessa says
I’d try Greek yoghurt (full fat, of course). Will tenderise the meat, too, if you leave it to marinated for a short time.
Frankie says
Not so much a mayo person, or rather it doesn’t like me. How would I get around that? I do love mustard, though. Have been paleo for 6 months with no weight change, so apparently I am where I ought to be weight-wise.

Kaylee says
What type of mustard do you use for this? It sounds delicious!
Mellissa Sevigny says
Either a whole grain mustard or a dijon mustard will work great – probably not so much the yellow hot dog mustard to get the best flavor! A horseradish mustard would also be yummy or even a honey mustard if the carbs aren’t too high! Enjoy!
