This keto Cubano Casserole has everything but the bread! I’ve used keto pulled pork instead of roasted pork in this version, but you can easily swap in your favorite roasted pork. Swiss cheese, sweet and salty chunks of ham, tangy pickles, and a robust mustard sauce combine to create a flavor explosion!

What You Need To Make Keto Cuban Casserole

You don’t need any fancy equipment or ingredients to make this leftover pulled pork casserole. Here’s what you’ll need:

  • 8 x 8 (or similar) oven-safe casserole dish
  • Leftover pulled pork – or thinly sliced and chopped roasted pork
  • Heavy whipping cream
  • Dijon mustard
  • Swiss cheese
  • Dill pickles
  • Ham
  • Sauce – the sauce is optional and the ingredients are below

Pickles in Casseroles? Isn’t that Weird?

Don’t be freaked out by the pickles! Cooked pickles, even the tangiest and strongest flavored ones, get a lovely mild and almost sweet flavor when cooked. They retain some of their crunch, adding texture to this dish. And, they add so much flavor. It just wouldn’t be a Cubano Casserole without pickles!

How To Make This Recipe

Recipes with leftover pulled pork have never been tastier! And, this casserole couldn’t be any easier. Here’s how to make it:

  1. Mix the leftover pulled pork with the cream and mustard in a large skillet. Heat it through until just staring to boil. Turn off the heat.
  2. Fold in half the Swiss cheese, half the ham, and about half the pickles.
  3. Check for seasoning and add a touch of salt and pepper if necessary.
  4. Put the pulled pork mixture into the bottom of an 8 x 8 (or similar sized) oven-safe casserole.
  5. Top the casserole with the remaining cheese, the ham, and the rest of the pickles.
  6. Bake at 400-F for about 15 minutes or until it is hot and bubbly.
  7. Top with the sauce and serve.

To Make the Sauce for the Leftover Pulled Pork Casserole

You’ll need:

  • Mayonnaise
  • Heavy whipping cream
  • Dijon mustard
  • Yellow mustard
  1. Combine the mayonnaise, heavy whipping cream, and mustards in a bowl. Mix well.
  2. Fill a sandwich size plastic zipper-top bag with the sauce mixture and zip it closed. Cut the tip off one of the bottom corners of the bag. Squeeze the bag lightly, using the bag to pipe out some of the sauce in a zig-zag pattern over the top of the casserole.
  3. Or, just add a dollop of the sauce to each serving.

Chef Jenn’s Tips

  • Leftover roast pork is an easy substitute for the pulled pork, just chop it up into small chunks.
  • Use a good-quality and not-too-salty ham. Sliced deli ham can be used in a pinch, or use leftover ham from a spiral ham or ham steak.
  • Don’t like Swiss cheese? Try this recipe with a mild cheese like gouda or jack.
  • Go for a strong dill pickle or make your own keto pickles for this recipe.
  • Don’t use dill pickle relish in this recipe – you need bigger chunks of pickle to get the full flavor.
  • I make big batches of smoked pork and pull it, freezing portions of it for use in recipes like this keto Cuban Casserole. You can also make smaller batches of keto Pulled Pork in your Instant Pot.

What To Serve With This Leftover Shredded Pork Recipe

This is a hearty and rich main dish. You want to keep your sides light. I’d suggest a simple but refreshing Tomato & Cucumber Salad or something like Bacon-Wrapped Asparagus.

Can I freeze This Leftover Pulled Pork Casserole REcipe?

You can, and it’ll be fine, but I prefer this dish fresh. When frozen and thawed, the ham and pickles give off more liquid and can make the dish kind of soupy. It’s fine to eat, and you can drain off some of the liquid if it bothers you.

To freeze it, thoroughly chill it in the fridge for a few hours or overnight. Then package the leftovers in an air-tight container and freeze for up to 3 months.

To eat, thaw it in the fridge or the microwave and heat it in a 300-F oven until heated through. Or, zap it in the microwave until it is hot.

Frequently Asked Questions

Are leftover pulled pork recipes keto?

Yes, they sure can be! Pulled pork, if rubbed with a sugar-free rub and with no sugary sauce on it is totally keto. So a casserole dish like this is an amazing leftover pulled pork recipe.

Is this recipe the same as a Cast Iron Cuban Casserole?

It’s got my own personal spin on it, Chef Jenn style, so no it’s not quite the same. And, I’ve included directions for using a regular casserole pan because not everyone has cast iron.

What kind of pickles should I use?

Pick a big dill pickle and cut it into 1/4-inch cubes.
