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…

Do you think that you could cook this ham in a pressure cooker instead?
Mellissa Sevigny says
Sure, but it wouldn’t have the nice crust on the outside – still delicious though!
Kirstie says
Hi Melissa,
I just wanted to tell you that I have made this recipe about 8 times since you posted it, and love it EVERY TIME. This is the only way that I make ham now, and I even shared it with my mom, who usually does the sugary glaze recipe. She loves it too. Great job!
Yvonne Escobar says
Do you cook it uncovered the entire time?
Mellissa Sevigny says
yes!

Thanks Jenna! I hope you enjoy the recipes – I know what you mean about looking for something new after a few months! It can be hard to stay the course when you are bored with all your old stand-by’s! Try the cauliflower puree – it’s one of my favorites!!!

Anna says
Hmmm…I’m not sure I’m sold. I can’t help but think of sweet with the salty ham, and don’t even really like that. Well, I guess I’ll try it….since they’re giving away ham these days ;).
Mellissa Sevigny (sevimel) says
Free ham, can’t beat it! :) I love the sweet salty thing but I found the mustard/rosemary combo to be really delicious too – let me know if you try it and it wins you over or not!
