"I don't know about you, but I am always looking for recipes that will help me use up all that leftover ham! This one is perfect (super easy), and my whole family loves it - probably because it's got ooey-gooey cheddar cheese." 🙂 - Kori

Delicious

Ham and cheese just seem to go together. That's what makes this ham casserole SO GOOD. I took this a step farther and threw in some vegetables (onions, spinach, and cauliflower) - any opportunity to sneak in vegetables is great!

Every time I make this recipe my family gobbles it up - they are the BEST and most vocal taste testers! Kitchen tested and family-approved.

🥘 Ingredients and Tools

Here's what you'll need to make leftover ham casserole recipe:

Ingredients

Cauliflower Florets - you can use fresh or frozen. For frozen you should cook in the microwave until crisp-tender only, it's easy to overcook so watch them carefully.
Olive oil
Onion
Baby Spinach
Cooked Ham - this can be leftover ham, or from a ham steak.
Sharp Cheddar Cheese
Sour Cream
Cream Cheese
Dijon Mustard
Fresh Parsley - try different herbs if you want! Chives and thyme are nice
Kosher Salt or Sea Salt
Pepper
Pork Panko or Seasoned Breadcrumbs - pork panko is the low carb option.

Tools

• 2.5 to 3-Quart Casserole Dish
• Cheese Grater
• Measuring Cups
• Measuring Spoons
• Whisk
• Mixing Spoon

Variations

Here are a few suggestions for varying or modifying this casserole:

• Try out different cheeses. Swiss or gouda would be delicious too!
• Substitute leftover diced chicken instead of ham.
• Don't feel limited to just parsley! Try a little thyme, chives, rosemary, even basil. Give it a French spin with herbs de Provence or an Italian spin with Italian seasoning.
• Feel free to substitute broccoli for cauliflower - broccoli cheese and ham - YUM.

🔪 Step by Step Instructions

Here's how to make ham casserole with cauliflower and cheese:

Preheat oven to 375 degrees F. Grease casserole dish with butter.

Cook Cauliflower

Cook cauliflower florets in salted boiling water for 5 minutes or until crisp-tender. Tip: you can also microwave steam with a few tablespoons of water - whichever method is easiest for you.

Run cold water over the cauliflower to stop the cooking. Strain cauliflower and set aside.

Cook Remaining Ingredients

In a 12" skillet over medium heat add olive oil and saute onion until soft.

Add spinach to the skillet and saute until wilted.

Add ham and cauliflower to pan and stir together.

Add 2 cups of cheddar cheese, sour cream, dijon mustard, parsley, salt, and pepper. Combine all ingredients.

Assemble Casserole

Transfer mixture over to casserole dish. Sprinkle the top with remaining cheese and then pork panko or seasoned breadcrumbs.

Bake

Bake for 20 to 25 minutes or until cheese is melted and casserole is bubbly.

Helpful Tips

• Do not overcook the cauliflower or it will become too soft and break down in your casserole. Cook to crisp-tender only.
• If you want to cut down on a pan use a 12" oven-proof skillet to cook and bake the casserole.

How do you store leftover ham?

Store any remaining ham in an airtight container or plastic bag in your refrigerator for up to 4 days.

Ham can be frozen if store in a freezer-safe airtight bag or container. I like to freeze ham slices in a plastic freezer bag. If I have a leftover ham bone I leave some of the ham on the bone and freezer for later use in soup.
