Ingredients for baked ham and cheese casserole
These twelve ingredients create the ultimate crispy-topped, melty-layered comfort masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Deli-Sliced Ham 🥓 | 1 ½ lb | High-quality, diced into 1/2-inch pieces |
| Swiss Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for rich sauce |
| Mayonnaise 🍳 | ½ cup | For creamy texture |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| All-Purpose Flour 🌾 | ½ cup | For sauce thickening |
| Butter 🧈 | ½ cup | Unsalted, softened |
| Biscuit Mix 🍞 | 16 oz | Like Pillsbury Grands |
| Garlic Powder 🧄 | 1 tbsp | For savory depth |
| Onion Powder 🧅 | 1 tbsp | For flavor balance |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Green Onion 🧅 | 2 tbsp | Chopped, for garnish |
The ham and cheese are the stars here—Black Forest or honey-glazed ham adds extra richness, but any good deli ham works. Kroger or Whole Foods carry excellent pre-sliced options, but if you're buying a whole ham, look for one with good marbling. Swiss cheese is non-negotiable for that perfect melt—block cheese always shreds better than pre-shredded. For the biscuit topping, Pillsbury Grands mix is my go-to because it guarantees that golden, crispy finish without fuss. The secret to the sauce? Full-fat dairy—skip the low-fat versions, trust me on this.
No heavy cream? Half-and-half plus a splash of milk works in a pinch, but the texture won't be quite as luxurious. Pre-shredded cheese has anti-caking agents that prevent proper melting—always shred your own from a block. Out of biscuit mix? Biscuits from a tube cut into diamonds work too, though they won't be quite as crispy. The garlic and onion powders are non-negotiable for that savory depth, but if you're feeling fancy, add 1/2 tsp of mustard powder for a subtle tang. For a vegetarian twist, swap the ham for smoked gouda cubes—it holds up beautifully.
This casserole reheats like a dream—5 minutes at 350°F with foil over the top to keep it moist. Store leftovers in the fridge for up to 5 days, but honestly, it disappears faster than that. The biscuit topping gets crispier the next day, so I always make extra. For holiday gatherings, double the recipe—it's a crowd-pleaser that scales perfectly. Freeze portions in individual servings for up to 3 months—just bake straight from frozen, adding 10 minutes to the cook time.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to scrub pots. Layer the ham and cheese, mix the creamy sauce (mayo, sour cream, heavy cream—yes, it’s that good), and let the oven do the work. No chopping, no fuss, just golden perfection.
- Creamy Crisp Contrast: The Swiss melts into gooey pockets while the top gets that just-right crisp—like a fancy grilled cheese but better. Honestly, the combo of salty ham and tangy cream sauce makes it impossible to stop at one serving.
- Weeknight & Potluck Star: Between us, this is my go-to for game day, Sunday dinners, or when my mom-in-law drops by unannounced. It reheats like a dream (microwave or oven, no judgment) and always gets raves—even from the picky eaters.
- Budget-Friendly Leftovers: I make a double batch because the flavor only gets richer overnight. The ham stretches thin, the cheese stretches further, and the creamy sauce turns into a dreamy dip for sandwiches the next day. Minimal cost, maximum meals.
Step-by-step instructions for baked ham and cheese casserole
Here's how to create that perfect balance of crispy golden topping and melty, savory layers.
Prepare the Creamy Ham Mixture
In a large bowl, combine the 1.5 lb deli-sliced ham with the 1 cup heavy cream, 0.5 cup mayonnaise, and 0.5 cup sour cream. I like to use my hands for this part—it helps break up the ham into even pieces while incorporating the creaminess. Add the 1.5 cups shredded Swiss cheese, 1 tbsp garlic powder, 1 tbsp onion powder, 1.5 tsp salt, and 0.5 tsp black pepper. Mix everything thoroughly until the cheese starts to melt slightly and the ham is fully coated in the creamy sauce.
This mixture is the heart of your casserole, so take your time. You want the cheese to be fully incorporated but not melted completely—just enough to create that smooth, velvety texture that'll make every bite irresistible. If you notice the cheese is clumping, use a rubber spatula to gently fold it in until you achieve a uniform consistency.
Create the Crispy Biscuit Topping
In a separate bowl, cut the 0.5 cup softened butter into small cubes and mix with the 16 oz biscuit mix. The butter should be soft enough to blend in easily but not melted—think slightly cooler than room temperature. Add the 0.5 cup all-purpose flour and mix until you have a crumbly, dough-like consistency. If the mixture feels too dry, add 1-2 tablespoons of milk (not listed in ingredients, but you'll have leftover cream) to help bind it together.
Here's where the magic happens: spread the biscuit mixture evenly over the ham mixture in your baking dish. Use your fingers or the back of a spoon to press it down gently but firmly. You want this topping to be about ¼-inch thick—thin enough to crisp up beautifully but thick enough to hold its shape. Don't worry if it looks uneven; the baking process will smooth it out.
Assemble and Bake to Golden Perfection
Preheat your oven to 375°F while you prepare the casserole. Grease a 9x13-inch baking dish (standard size works perfectly) and transfer the ham mixture into it, spreading it out evenly. This is your base layer—smooth it with a spatula so it's level. Then carefully spread the biscuit topping over the ham mixture, pressing down lightly to ensure good contact between the layers.
Bake for 30-35 minutes until the top is deep golden brown and the edges are bubbling. The biscuit topping should be crispy enough to hold its shape when you lift it slightly with a spatula. If you're unsure, check at the 25-minute mark—ovens vary, and you want that perfect balance of crispy and creamy. The internal temperature should reach 160°F when measured in the ham center.
Rest and Garnish for Maximum Comfort
Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This resting period allows the layers to set slightly and makes it easier to slice—trust me, it's worth the wait. While it rests, chop the 2 tbsp green onion and sprinkle them evenly over the top for a fresh pop of color and flavor.
Slice into 6 generous portions (about 1 cup each) and serve immediately. The contrast between the crispy biscuit topping and the creamy, cheesy ham filling is what makes this casserole so irresistible. Each bite delivers that perfect combination of textures and flavors—salty ham, rich cheese, and that buttery, crispy top that just melts in your mouth.
Pro Tips For Making Baked Ham And Cheese Casserole
- Preheat and Grease Like It’s 1987: Bake the ham and cheese casserole in a cold dish—yes, cold. Toss it in the oven with the preheated broiler for the last 3-5 minutes, and you’ll get that golden, bubbly top without a sad, soggy mess. I learned this the hard way when my first attempt looked like a science experiment gone wrong.
- Drain the Ham—Seriously: Skip the pre-sliced ham’s juice? Big mistake. Pat those slices thoroughly with paper towels before layering—wet ham means a watery casserole. If you’re lazy (I know, I know), at least let it sit in a colander for 10 minutes to shed some moisture first.
- Mix the Cream Sauce Early: Combine the heavy cream, mayo, and sour cream before assembling the casserole. This lets the flavors meld and thickens the sauce slightly, so it doesn’t turn into a gluey disaster when baked. Stir it in cold, then dump it over the ham and cheese—no last-minute scrambling.
- Press the Cheese Down Hard: Don’t just sprinkle Swiss cheese on top like confetti. Press it firmly into the layers so it melts into a cohesive blanket, not a few sad clumps. Use a spatula or even your hand—this is the thing that matters most for that restaurant-style finish. (Yes, even if you’re impatient like me.)
Storing and reheating this baked ham and cheese casserole
Refrigerator Storage
Store leftovers in an airtight container for up to 5 days at 40°F or below. The biscuit topping actually gets crispier after the first night, so I always make extra. Let it cool completely before covering—condensation is the enemy of crispy tops. 🥫
Freezer Prep Tips
For long-term storage, freeze individual portions in quart-sized freezer bags with 1 inch headspace for expansion. I recommend wrapping each portion tightly in plastic wrap before bagging to prevent freezer burn. Label with dates—this casserole stays delicious for 3 months when frozen properly.
Oven Reheating
For the best texture, bake straight from frozen at 375°F for 45-50 minutes (add 10 minutes to original cook time). Cover loosely with aluminum foil for the first 20 minutes to prevent over-browning. Remove foil and bake until the biscuit topping is golden brown again.
Microwave Method
For quick reheating, cover with a damp paper towel and microwave at 50% power for 3-4 minutes, stirring halfway. Add 1-2 tablespoons of water or cream if the casserole looks dry. The biscuit topping won't be as crispy but still delicious—perfect for busy weeknights.
Serving Leftovers
Serve reheated portions with a side salad or steamed vegetables to balance the richness. I like adding toasted walnuts or crumbled bacon on top for extra crunch. The flavors actually improve after the first day—this is one casserole that tastes better tomorrow! 🍽️

Frequently asked questions
Can I make this casserole ahead of time?
This dish actually tastes better the next day. Assemble it completely (including the biscuit topping) and refrigerate uncovered for 1-2 hours before baking to help the flavors meld. For a make-ahead holiday meal, prepare everything except the topping, refrigerate overnight, then add the biscuit layer and bake straight from the fridge—just add 5-10 extra minutes to the baking time. The biscuits will still get crispy!
What if I don't have biscuit mix?
No problem! Use 16 oz refrigerated biscuits cut into diamonds or make a quick topping with 1 cup crushed crackers (like Ritz) mixed with 0.5 cup melted butter. For a gluten-free option, try crushed gluten-free pretzels with melted butter—it adds a nice salty crunch. The texture won't be identical, but it'll still be delicious.
Can I use a different type of cheese?
Swiss cheese is ideal for its meltiness, but you can substitute with sharp cheddar (for tang), Gruyère (for nutty depth), or smoked gouda (for smoky flavor). Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. For a vegetarian version, use smoked gouda or pepper jack instead of ham. The key is using block cheese that shreds smoothly.
Why did my biscuit topping get soggy?
Soggy topping usually means the ham mixture was too wet or the biscuit layer wasn't thick enough. For next time, press the biscuit topping firmly and bake at 375°F until it's deep golden brown. If it's still soggy, try adding 1/4 cup crushed cornflakes to the biscuit mix for extra crispiness. Also, make sure your oven isn't too hot—too much heat can cause the bottom to cook faster than the top.
How do I make this gluten-free?
Replace the biscuit topping with crushed gluten-free crackers (like Schär) mixed with 0.5 cup melted butter and 1 tbsp melted butter for binding. For the sauce, use gluten-free mayonnaise and sour cream. Check all spice blends for hidden gluten—stick to single-ingredient spices. The texture will be slightly different but still delicious. For extra crispiness, sprinkle gluten-free breadcrumbs on top before baking.
