Low Carb 3-Ingredient Ham Pembroke Bombs are a quick, cheesy casserole made with layers of low-carb tortillas, savory deli ham, and melted sharp cheddar cheese.
The tortillas become tender around the center and lightly crisp along the edges, while the cheddar creates a bubbly, golden topping.
With only three main ingredients and about 10 minutes of preparation, this easy ham and cheese tortilla bake works well for busy weeknight dinners, casual gatherings, game-day snacks, and potlucks.
Once baked and rested, the casserole can be cut into neat squares that are easy to serve directly from the pan.
The final carbohydrate content will depend on the tortillas you choose, so check the package label if you are following a specific low-carb eating plan.

Ingredient Notes
Choose tortillas that are specifically labeled low-carb or carb-conscious. Different brands contain different amounts of carbohydrates, so compare their nutrition labels before purchasing.
Thinly sliced deli ham is easiest to layer and helps the finished casserole hold together. If the slices are large, cut or fold them so they fit neatly inside the baking pan.
Freshly shredded cheddar usually melts more smoothly than packaged pre-shredded cheese. Sharp cheddar gives the dish a stronger flavor, but mild or medium cheddar can also be used.
How to Make Ham Pembroke Bombs
1. Prepare the Oven and Pan
Preheat the oven to 375°F (190°C).
Lightly grease an 8-inch square baking dish or a similar disposable foil pan. Greasing the bottom and corners helps prevent the melted cheese from sticking and makes the squares easier to remove.
2. Cut the Tortillas
Lay the low-carb tortillas on a clean work surface. Cut them into halves, quarters, or smaller pieces as needed to fit your baking dish.
The tortilla pieces do not need to look perfect. Arrange them so they cover most of the bottom without creating an excessively thick base.
3. Assemble the Layers
Place a single layer of tortilla pieces across the bottom of the prepared pan. Top them with an even layer of sliced ham, followed by a generous layer of shredded cheddar.
Repeat the tortilla, ham, and cheese layers until all the ingredients have been used. Finish with an even layer of cheddar cheese on top.
Avoid pressing the layers too firmly. A loose arrangement allows the cheese to melt between the pieces and helps heat circulate through the casserole.
4. Bake Until Golden
Place the uncovered pan in the preheated oven and bake for 20–25 minutes.
The casserole is ready when the cheese has completely melted, the edges are bubbling, and the top has developed lightly browned spots. If you prefer a deeper golden surface, place it briefly under the broiler while watching it carefully to prevent burning.
Because deli ham is generally sold fully cooked, the goal is to heat the casserole thoroughly and melt the cheese. If using another type of ham, confirm that it is fully cooked before assembling the dish.
5. Rest and Serve
Remove the pan from the oven and allow the casserole to rest for 5–10 minutes. This short resting period is important because it allows the melted cheese and tortilla layers to settle.
Cut the casserole into eight squares and serve warm.
Tips for the Best Results
Prevent a Soggy Casserole
Avoid using watery additions such as fresh tomatoes directly between the layers. Extra moisture can soften the tortillas too much and make the squares difficult to lift from the pan.
Create Crispier Edges
Use a metal or disposable foil pan and spread the top layer of cheese all the way into the corners. The cheese touching the edges of the pan will become browned and slightly crisp.
Let It Rest Before Cutting
The casserole will be very soft immediately after baking. Resting it for at least five minutes produces cleaner slices and prevents the filling from sliding apart.
Adjust the Cheese
Sharp cheddar provides a bold flavor that balances the mild tortillas and salty ham. For a gentler flavor, substitute mild cheddar. Monterey Jack, pepper jack, or a cheddar blend can also work, although they technically change the original three-ingredient combination.
Optional Variations
The basic recipe requires only three ingredients, but the following optional additions can change the flavor:
Sprinkle black pepper or garlic powder between the layers.
Spread a very thin layer of Dijon or yellow mustard over the tortillas.
Use pepper jack cheese for a slightly spicy version.
Add a small amount of chopped pickled jalapeño.
Replace part of the cheddar with mozzarella for a stretchier cheese pull.
Keep additions light so the casserole remains easy to slice and does not become too wet.
What to Serve With It
These cheesy ham tortilla squares are rich and filling, so they pair best with something fresh or lightly seasoned. Serve them with:
A crisp green salad
Roasted broccoli or cauliflower
Sliced tomatoes
Dill pickles
Sugar-free coleslaw
Cucumber salad
Steamed green beans
For a party platter, cut the casserole into smaller portions and serve them alongside deviled eggs, raw vegetables, and a low-sugar dipping sauce.
Storage and Reheating
Allow leftovers to cool, then transfer them to an airtight container. Refrigerate for up to 3–4 days.
Reheat individual pieces in the microwave until hot, or place them in a 350°F (175°C) oven for approximately 10 minutes. The oven or an air fryer will preserve the edges better than the microwave.
Freezing is possible, but some low-carb tortillas may become softer after thawing. Wrap individual cooled portions securely and freeze them for up to one month. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Are Ham Pembroke Bombs Really Low Carb?
They can be low in carbohydrates when made with genuinely low-carb tortillas. The exact amount varies significantly by brand, so always calculate it using the labels on your tortillas, ham, and cheese.
Can I Prepare the Casserole Ahead of Time?
Yes. Assemble it, cover the pan, and refrigerate it for several hours. Take it out while the oven preheats, then bake as directed. It may require a few additional minutes if it is still cold.
Can I Double the Recipe?
Yes. Double the ingredients and assemble them in a 9-by-13-inch baking dish. The baking time may need to be extended slightly. Check that the center is thoroughly hot and the cheese is bubbling before removing it from the oven.
