One of the things that I’ve been craving since I got pregnant? PROSCIUTTO.

Of course, that just so happens to be on the “no” list for pregnancy… UNLESS you heat it up.

So that’s been my main mission – figuring out all the ways to heat up prosciutto to get my fix and make it taste amazing.

a Cake ‘n Knife favorite:


For me, this breakfast croissant sandwich has everything I could ever want. It has the buttery croissant. There’s the gooey cheese. A hit of salt from the prosciutto. Not to mention a burst of acidic punch from cherry tomatoes!

Finally, the spread of whole grain mustard and fig jam bring a sweet and tangy mix to the sandwich. Fresh out of the oven and paired with a mug of coffee, it’s everything I want to start the say with.

Plus, as a pregnant lady who needs her fixes wherever the heck she can get them, I will gladly eat these every day until forever. Or until another food aversion decides to rear its ugly head.

this recipe’s must-haves

Since this recipe is so darn simple, you don’t have to do much and you don’t need a ton of tools. You will need your favorite rimmed half baking sheet pan to bake up the sandwiches.

In addition, you’ll need a chef’s knife or bread knife and a cutting board to assemble the sandwich. That’s it!

Roast Tomatoes

Roasted cherry tomatoes are one of my favorite sandwich toppers. All you have to do is toss them on a baking sheet and bake them for about 10 minutes.

Assemble & Bake

Now it’s time to assemble. Slice the croissants in half and spread the bottom half with mustard. Now pile on the cheese, prosciutto, and burst tomatoes. Finally spread the top half with jam!

Bake until the cheese is all gooey and eat immediately! You can also let them cool and wrap them up in aluminum foil. They will keep in the refrigerator for about 3 to 4 days so you can warm one up each morning for breakfast on the go!

got questions?

Why is there no egg in this breakfast sandwich?

First off, eggs are on the no fly list in our house right now. I just can’t. HOWEVER, you can totally upgrade the sandwich to add in an extra egg or two if you need. You can use a fried egg or even scrambled eggs in this sandwich.

Can I use another type of jam?

I love the taste of fig jam with prosciutto, but you can also substitute your favorite jam like peach, strawberry, or raspberry.
