How to Make 3-Cheese Pumpkin Pasta Casserole with Spinach

Step 1: Cook the Pasta

Start by boiling your pasta in salted water until it’s al dente. This means it should be tender but still have a slight bite, so it doesn’t get mushy once baked in the casserole.

Step 2: Sauté Aromatics and Spinach

While the pasta cooks, heat olive oil or butter in a large skillet and sauté chopped onions and minced garlic until fragrant and translucent. Add fresh spinach and cook just until wilted, preserving its vibrant color and nutrients.

Step 3: Prepare the Pumpkin Cheese Sauce

In the same skillet, stir in pumpkin puree and let it warm through. Add cream cheese, mozzarella, and freshly grated Parmesan, stirring continuously until the cheeses melt into a creamy sauce. Slowly pour in milk or cream to achieve a smooth consistency, seasoning with salt, pepper, nutmeg, and sage for a cozy fall flavor blend.

Step 4: Combine Pasta and Sauce

Drain the pasta and mix it well with the pumpkin cheese sauce and sautéed spinach mixture. Make sure every bite gets an even coating of that luscious sauce.

Step 5: Bake the Casserole

Transfer the mixture to a greased baking dish, sprinkle a little extra mozzarella and Parmesan on top for a golden crust, and bake at 350°F (175°C) for about 20-25 minutes until bubbly and lightly browned.

Pro Tips for Making 3-Cheese Pumpkin Pasta Casserole with Spinach

• Don’t overcook pasta: Al dente pasta absorbs sauce better and prevents a soggy casserole.
• Use fresh pumpkin puree: Homemade or canned, fresh puree ensures natural sweetness without added sugars.
• Grate your own cheese: Pre-grated cheese can contain additives that affect melt and texture.
• Season gradually: Add spices little by little and taste to balance pumpkin’s natural sweetness.
• Let it rest before serving: Allow the casserole to cool for 5-10 minutes to set and make slicing easier.

How to Serve 3-Cheese Pumpkin Pasta Casserole with Spinach

Garnishes

Side Dishes

Serve this casserole with a crisp, tangy green salad dressed in lemon vinaigrette to cut through the creamy richness. Warm crusty bread or garlic breadsticks also make perfect companions for dipping into any leftover sauce.

Make Ahead and Storage

Storing Leftovers

Keep leftovers in an airtight container in the refrigerator for up to 3-4 days. The flavors will deepen overnight, making the next meal just as tasty as the first.

Freezing

This casserole freezes beautifully. Portion it out into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge before reheating for best results.

Reheating
