This Greek Spaghetti Casserole beautifully marries the beloved flavors of Italian and Greek cuisines into one comforting dish. The combination of tender pasta, aromatic vegetables, and two types of cheese creates a Mediterranean masterpiece that's both familiar and excitingly different.

I've made this casserole countless times for family gatherings, and it never fails to spark conversations about its unique flavor profile. My sister-in-law even requested it for her birthday dinner last year.

Essential Ingredients and Selection Tips

  • Spaghetti: Use high-quality durum wheat pasta that holds shape when baked
  • Bell Peppers: Choose firm, brightly colored ones for best flavor
  • Mushrooms: Fresh button mushrooms provide earthy depth
  • Black Olives: Kalamata works best for authentic Greek flavor
  • Mozzarella & Cream Cheese: Full-fat versions create the creamiest result
  • Oregano: Mediterranean oregano offers the most authentic taste

Step-by-Step Instructions

Step 1: Pasta Preparation
Break spaghetti in half for easier serving. Cook until just al dente as it will continue cooking in the oven.
Step 2: Vegetable Base
Sauté vegetables in butter until tender but not mushy. Allow oregano to bloom in the warm butter for enhanced flavor.
Step 3: Sauce Creation
Combine tomatoes and olives, simmering to meld flavors. Whisk cream cheese and milk until smooth.
Step 4: Assembly and Baking
Combine all elements while pasta is still warm. Bake until edges are golden and cheese is perfectly melted.

My grandmother always emphasized using fresh bell peppers in this dish. She swore they provided not just flavor but also essential vitamins that kept our family healthy through winter months.

Storage and Serving

  • Keeps well in the refrigerator for up to 4 days
  • Freezes beautifully for up to 3 months
  • Best reheated in the oven at 350°F for 20 minutes
  • Pairs perfectly with a simple Greek salad

After years of perfecting this recipe, I've found it's more than just a fusion dish - it's a conversation starter that brings people together. The way the cream cheese melts into little pockets of richness while the Greek elements add their distinctive character makes this casserole truly special. Every time I serve it, I'm reminded of how food can bridge different culinary traditions so beautifully.
