Some of the best recipes are the ones scribbled on old index cards, and these low carb 3-ingredient ham hathaway crisps feel exactly like that kind of kitchen treasure. With just ham, provolone, and a little Dijon mustard, you get a salty, crispy, cheesy bite that works as a quick snack, easy lunch, or last-minute party plate. It is the kind of practical recipe busy home cooks love because it comes together fast, uses simple ingredients, and somehow disappears almost as soon as it hits the table.
Serve these crisps warm on their own, or pair them with a simple green salad, a cup of tomato soup, crunchy pickle spears, or a veggie tray for an easy low carb spread. They also fit nicely onto a brunch board with eggs and fruit, or as a savory appetizer with sparkling water, iced tea, or a crisp white wine.
Low Carb 3-Ingredient Ham Hathaway Crisps
Servings: 4
Ingredients
8 slices deli ham
8 slices provolone cheese
2 teaspoons Dijon mustard
Directions
1. Preheat your oven to 400°F and line a large baking sheet with parchment paper. Set the ham slices, provolone, and Dijon out so assembly goes quickly.
2. Lay the ham slices on the prepared baking sheet, leaving a little space between each one. Spread about 1/4 teaspoon of Dijon mustard over each slice.
3. Top each ham slice with a piece of provolone, folding or trimming slightly if needed so the cheese mostly fits the ham.
4. Bake for 10 to 14 minutes, until the cheese is melted and deeply golden around the edges and the ham has browned and crisped.
5. Let the crisps cool on the pan for 2 to 3 minutes so they firm up, then transfer to a plate and serve warm.
Variations & Tips
Mustard Swap: If Dijon is not your favorite, try spicy brown mustard for a slightly sharper flavor. Just keep the layer light so the crisps stay crisp instead of soggy.
Cheese Option: Provolone gives a nice melt and browns beautifully, but Swiss works well too if you want a more classic ham-and-cheese flavor. Watch the oven closely since different cheeses brown at different speeds.
Make Them Smaller: For party snacks, cut the ham and cheese into halves or quarters before baking. The smaller pieces crisp faster and are easy to serve on a platter for gatherings.
Best Texture Tip: These are at their best warm from the oven after a short rest. If you want them extra crisp, leave them on the parchment an extra minute or two before moving them to the plate.
Meal Prep Note: You can assemble the ham, mustard, and cheese on the baking sheet a few hours ahead and refrigerate until ready to bake. That makes this recipe especially handy for busy workdays or quick appetizers before company arrives.
