Yes — mortadella is mostly pork and fat, which fits keto well. Just glance at the label, as a few brands add a little sugar or starchy filler. Enjoy it in normal sandwich portions.

What bread do you use for a keto sandwich?

We use our Ultimate Keto Loaf — a real, sliceable, toastable keto bread that stays low-carb. It's what lets you build a proper deli ham and cheese sandwich at around 4–6g net carbs instead of 40–50g.

How many carbs are in this keto ham and cheese sandwich?

About 4–6g net carbs when built on the Ultimate Keto Loaf with mortadella and Havarti. The same sandwich on ciabatta is closer to 40–50g net carbs — the bread is almost the entire difference.

Can I meal-prep this sandwich?

Yes. Keep the mortadella, Havarti and sprouts ready and assemble fresh. If you like it crisp, butter the outside and pan-sear or air-fry just before eating so the Ultimate Keto Loaf stays crisp rather than soggy.

Keto Mortadella & Cheese Deli Sandwich

Keto mortadella and cheese deli sandwich made with the Ultimate Keto Loaf

Look at that: layers of mortadella, creamy Havarti, and fresh alfalfa sprouts stacked on golden keto bread — a proper deli sandwich that’s completely keto. Think of it as a next-level, low-carb take on the classic ham and cheese (mortadella is the smooth Italian cousin of ham). The secret is the bread: it’s built on our Ultimate Keto Loaf, so you get the full deli-sandwich experience at around 4–6g net carbs instead of the 40–50g you’d get from ciabatta.

Why it’s keto: the Ultimate Keto Loaf (UKL) does the heavy lifting — a real, sliceable, toastable bread that stays low-carb. Everything else — mortadella, Havarti, sprouts, mayo — is already keto.

Ingredients

Makes 1 sandwich.

2 slices Ultimate Keto Loaf — our signature keto bread, from the Keto Pantry.
4–5 slices mortadella.
1 slice Havarti cheese.
A handful of alfalfa sprouts.
Mayonnaise — to spread.
Butter — optional, if you want a crisp toasted sandwich.

How to make it

1. Spread the mayo. Spread mayonnaise on the inner sides of both slices of Ultimate Keto Loaf.
2. Layer it up. Stack the mortadella, Havarti, and alfalfa sprouts between the two slices.
3. (Optional) Make it crisp. Spread butter on the outer surfaces of the top and bottom slices.
4. Pan-sear or air-fry. Cook until the bread is golden and the Havarti softens — a few minutes per side in a pan, or a quick crisp in the air fryer. Prefer it cold? Skip this step and serve as-is.
5. Slice & serve. Cut and enjoy — warm and crisp, or cold and fresh.

⚠ A couple of things to watch

Sweet-cured deli meats — some cold cuts have added sugar. Mortadella is usually fine; just glance at the label.
Swapping in regular bread — the Ultimate Keto Loaf is what keeps this keto; ordinary bread or ciabatta would undo it.
“Light” or sweet mayo — some have added sugar or starch; a plain full-fat mayo is the keto choice.

Tips & swaps

Air fryer is easiest: buttered and air-fried, the loaf crisps up beautifully with no flipping.
Add richness: a few slices of avocado or a thin tomato slice work beautifully.
Make it heartier: a fried egg on top turns this into a full keto breakfast.
Meal-prep friendly: keep the components ready and assemble fresh so the loaf stays crisp.
