Hot “Unwich” Ham and Cheese Casserole:

Sandwiches are such an easy meal! They are entirely customizable, filling, and perfect for on-the-go lunches. So, I decided to make a keto unwich recipe! The unwich contains all the ingredients you love in a sandwich minus the bread!

This recipe is easy and perfect for a quick lunch or weeknight meal; you can use whatever deli meat, cheese, and toppings you would like!

Ingredients You’ll Need

  • smoked deli ham- Make sure not to get honey ham or brown sugar ham since it will add carbs. If you do not like ham, feel free to use turkey, sliced chicken, or your favorite keto deli meat.
  • Swiss cheese—I prefer to use Swiss cheese for this recipe because of its flavor; however, you can use whatever type of cheese you like.
  • Dill pickles – I love pickles on my sandwiches and use slices or chopped pickles, depending on what I have on hand.
  • Italian seasoning, Italian dressing – Adds tons of extra flavor to this unwich recipe.

Steps for making Keto Hot “Unwich” & Cheese Casserole:

Step 1: Spray a 9×9 pan with pam so that the casserole does not stick, and lay down your first layer of ham. It should be about 4 total ham slices.

How to Make a Spicy Unwich:

You could add some hot sauce to the keto ham and Swiss casserole; however, make sure that it is low-carb before adding it. You could also use spicy pickles instead of regular pickles and pepper jack cheese to kick the heat up a notch.

Variations to the Unwich:

This is such an easy casserole to make your own; here are some of my favorite variations you could try!

  • Try different meats such as roast beef, salami, or turkey!
  • Use different cheese. Not everyone likes Swiss cheese, so you could use provolone cheese, sharp cheddar cheese, or whatever you prefer!
  • Create lettuce wraps by slicing a piece of the unwich and putting it in romaine lettuce hearts! This variation adds a little bit of crunch and texture to the dish. This is similar to Jimmy John’s style of unwich.
  • You could also try adding different keto sauces such as hot sauce, dijon mustard, yellow mustard, or even mayo.

How to Store Leftover Unwich?

To store, place the leftover pieces in an airtight container in the fridge for 3-5 days. To reheat, simply put in the microwave for 30 seconds, then the oven or air fryer for just a few minutes to crisp up the ham and cheese.

Can You Meal Prep this Keto Unwich?

Yes, you absolutely can! To meal prep, follow all the recipe card instructions, but do not bake the keto ham and Swiss casserole until you are ready. This recipe can stay good in the fridge for up to 5 days.

While this is an easy meal prep recipe, I do not recommend freezing it. The dressing and moisture of the deli meat will cause it to thaw with a different texture.

    1. I did not include the nutritional info as it will depend on how each person makes it and the ingredients they use.

    2. I ran the macros based on 4 servings, and they are 3 g. carbs, 2 g. net carbs, 24 g. fat, 22 g. protein, and 315 calories. This is very filling so it is conceivable to get 6 servings from this dish. Don’t skip or skimp on the dill pickles. They make the dish pop.

  1. I was skeptical at first about this recipe: Italian dressing on ham and cheese? So glad we gave it a try… It was incredibly delicious! That’s two recipes so far…the first one was the queso soup; THAT was fabulous! You have new followers…resistance is futile!

    1. Thanks for that question Teri or I would’ve only done 1 layer of ham as the instructions do not mention another. Looks really good!

    1. I didn’t measure it. I would say I didn’t use a lot of the Italian dressing. The good thing is that you can always add more when it’s done if you don’t feel like you’ve added enough.

    1. It depends on how you cut the casserole. I did not include serving size or nutritional info because it will depend on the exact ingredients you use.

  2. I’m going to be starting Keto soon and I’m doing a lot of research and prepping right now. You’d use like just regular Italian Dressing, right? Not low-fat or low-cal or anything.

  3. Your recipes are all amazing! They have been my “go to” for low carb food and I’m so impressed! This recipe and the Queso soup are my absolute favs! Can’t wait to try more. Thank you for sharing all this yumminess with the world! 🙂

    1. Hey Polly, I just realized this recipe does not have a recipe card. Sorry! You can always do a print screen or copy and paste.

    1. I do not have a recipe card for this recipe yet. So, the number of servings would depend on the size of your servings.
