Why You’ll Love This Cheesy Ham and Pea Casserole
This casserole isn’t just delicious — it’s practical, adaptable, and deeply satisfying.

Ingredients:
Everything You Need for Creamy, Cheesy Success
- 12 oz pasta (penne, rotini, or shells work best)
- 2 cups cooked ham, diced
- 1 ½ cups frozen peas (no need to thaw)
- 3 cups shredded cheddar cheese (sharp or medium)
- 3 tbsp unsalted butter
- 3 tbsp all-purpose flour
- 2 ½ cups whole milk
- 1 small onion, finely diced
- 2 cloves garlic, minced
- ½ tsp salt
- ½ tsp black pepper
- ½ tsp paprika
- ¼ tsp nutmeg (optional, but recommended)
- ½ cup grated Parmesan cheese (optional topping)
- Chopped parsley, for garnish
Instructions:
Step-by-Step Cheesy Perfection
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish and set aside.
- Cook pasta in well-salted boiling water until just al dente. Drain and set aside.
- In a large skillet over medium heat, melt the butter. Add diced onion and cook until soft and translucent, about 4–5 minutes.
- Add minced garlic and cook for 30 seconds until fragrant.
- Sprinkle flour over the onion mixture and stir continuously for 1 minute to form a roux.
- Slowly whisk in the milk, stirring constantly to avoid lumps. Cook until the sauce thickens, about 3–4 minutes.
- Season the sauce with salt, black pepper, paprika, and nutmeg.
- Remove from heat and stir in 2 cups of shredded cheddar cheese until fully melted and smooth.
- In a large mixing bowl, combine cooked pasta, diced ham, frozen peas, and cheese sauce. Mix until evenly coated.
- Transfer the mixture into the prepared casserole dish and spread evenly.
- Sprinkle remaining cheddar cheese and optional Parmesan over the top.
- Bake uncovered for 25–30 minutes, or until bubbly and golden on top.
- Let rest for 5 minutes before serving. Garnish with chopped parsley if desired.
The Secret to Ultra-Creamy Casseroles
The key to a perfectly creamy casserole lies in the roux-based sauce. Cooking the flour with butter before adding milk eliminates any raw flour taste and creates a silky base that won’t separate during baking. Using whole milk and freshly shredded cheese ensures maximum creaminess and meltability.
Avoid pre-shredded cheese when possible, as it often contains anti-caking agents that prevent smooth melting.
Variations to Try
One of the best things about Cheesy Ham and Pea Casserole is how customizable it is.
- Extra Crunch: Add buttered breadcrumbs or crushed crackers on top before baking.
- Different Cheese: Swap cheddar for Gruyère, Swiss, or mozzarella for a different flavor profile.
- Vegetable Boost: Add sautéed mushrooms, spinach, or broccoli florets.
- Low-Carb Option: Replace pasta with steamed cauliflower or zucchini slices.
- Spicy Twist: Stir in a pinch of cayenne or a splash of hot sauce.
Serving Suggestions
This casserole is hearty enough to stand alone, but it pairs beautifully with simple sides.
Serve it with a crisp green salad, roasted vegetables, or warm crusty bread to soak up every bit of that creamy sauce. For gatherings, it works wonderfully alongside other comfort classics like roasted chicken or glazed carrots.
Make-Ahead and Storage Tips
This recipe is perfect for meal prep.
- Make Ahead: Assemble the casserole, cover tightly, and refrigerate up to 24 hours before baking.
- Freezing: Freeze unbaked or baked casserole for up to 3 months. Thaw overnight before reheating.
- Leftovers: Store in an airtight container in the refrigerator for up to 4 days.
Reheat gently in the oven or microwave, adding a splash of milk if needed to restore creaminess.
