Save I threw this together on a gray November afternoon when the fridge was still packed with turkey and I couldn't bear another plain sandwich. The idea came from a joke about that famous TV Thanksgiving episode, but once I tasted the gravy-soaked middle layer, I stopped laughing and started taking notes. It's become my go-to for turning leftovers into something people actually get excited about. The first time I brought it to a potluck, someone asked if I'd opened a secret comfort food restaurant. I hadn't, but I did write down the recipe on a napkin three times that night.
I made this for my sister's family the weekend after Christmas, and her kids devoured it without asking what was inside. My brother-in-law, who usually avoids casseroles, went back for thirds and texted me the next morning asking for the recipe. That's when I knew it had crossed over from leftover solution to legitimate dinner win. It's one of those dishes that makes you feel like a kitchen genius even though it's almost embarrassingly simple to pull off.
Ingredients
- Penne or rigatoni: The ridges and tubes catch the sauce and gravy, making every forkful satisfying; cook it just shy of tender since it bakes later.
- Turkey or chicken gravy: This is the soul of the dish, the secret moisture layer that makes it unforgettable; homemade is wonderful, but a good jar works too.
- Cooked turkey breast: Shred or chop it into bite-sized pieces so it distributes evenly; rotisserie chicken is a perfect stand-in if you don't have turkey.
- Mozzarella, cheddar, and Parmesan: The trio creates layers of creamy, sharp, and nutty flavor; freshly shredded melts better than pre-shredded.
- Onion and garlic: Sautéed until soft, they build a savory base that keeps the casserole from tasting flat.
- Whole milk and flour: Together they form a simple, silky sauce that binds the pasta and turkey without feeling heavy.
- Frozen peas: Optional but lovely for little pops of sweetness and color; no need to thaw them first.
- Dried thyme, black pepper, salt: Just enough to lift the flavors without competing with the gravy's personality.
Instructions
- Prep the oven and dish:
- Set your oven to 190°C (375°F) and grease a 9x13-inch baking dish so nothing sticks. This step sounds obvious, but I've learned the hard way that a well-greased dish makes cleanup so much easier.
- Cook the pasta:
- Boil the penne or rigatoni in salted water until just al dente, then drain and set aside. It will continue cooking in the oven, so underdone is better than mushy.
- Sauté the aromatics:
- Heat olive oil in a skillet over medium heat and cook the chopped onion until soft and translucent, about 5 minutes. Stir in garlic, thyme, salt, and pepper, cooking for another minute until fragrant.
- Make the sauce:
- Sprinkle flour over the onions and stir for a minute to cook off the raw taste. Gradually whisk in the milk, stirring constantly until the sauce thickens, about 2 to 3 minutes, then stir in the butter until it melts into the sauce.
- Combine the base:
- In a large bowl, mix the cooked pasta, onion sauce, turkey, peas if using, and half of each cheese. Toss gently so everything gets coated evenly.
- Layer the casserole:
- Spread half the pasta mixture into the greased baking dish, pressing it down gently. Pour or spoon the gravy evenly over this layer, letting it soak in for that signature moist maker magic.
- Top and finish:
- Add the remaining pasta mixture on top, spreading it evenly, then sprinkle with the rest of the mozzarella, cheddar, and Parmesan. The cheese will turn golden and bubbly as it bakes.
- Bake until golden:
- Slide the dish into the oven and bake uncovered for 30 to 35 minutes, until the top is golden and the edges are bubbling. Let it rest for 10 minutes before serving so the layers set and you don't burn your mouth.
Save The first time I served this at a casual dinner party, someone said it tasted like a hug in a baking dish. That might sound cheesy, but it's exactly the vibe this casserole gives off: warm, generous, and impossible to resist. It's the kind of food that turns a regular Tuesday into something a little more special, and it does it without you breaking a sweat.
How to Store and Reheat
Let the casserole cool completely, then cover it tightly with foil or transfer portions to airtight containers. It keeps in the fridge for up to four days and tastes even better the next day when the flavors have had time to settle. Reheat individual servings in the microwave or warm the whole dish in a 180°C (350°F) oven for about 20 minutes, covered with foil so the top doesn't dry out. I sometimes add a splash of milk or extra gravy before reheating to bring back that just-baked moisture.
Variations and Swaps
Swap the turkey for rotisserie chicken, leftover ham, or even a mix of both if you're cleaning out the fridge. Toss in sautéed mushrooms, chopped spinach, or diced bell peppers for extra vegetables and color. For a gluten-free version, use gluten-free pasta and swap the flour for a gluten-free blend or cornstarch. You can also experiment with different cheeses like Gruyère or fontina for a richer, more sophisticated flavor, though the classic trio is hard to beat.
Serving Suggestions
This casserole is hearty enough to stand on its own, but it pairs beautifully with a crisp green salad dressed in lemon vinaigrette to cut through the richness. Serve it with crusty bread or garlic bread for soaking up any extra gravy on the plate. A light side of roasted Brussels sprouts or green beans adds a nice contrast in texture and freshness.
- Make it ahead and refrigerate unbaked for up to 24 hours, then bake straight from the fridge, adding 10 extra minutes to the cook time.
- Freeze assembled but unbaked casserole tightly wrapped for up to three months, thaw overnight in the fridge before baking.
- Sprinkle fresh parsley or chives on top before serving for a pop of color and a hint of brightness.
Save This is the kind of recipe that makes you look forward to leftovers, and that's saying something. Whether you're feeding a crowd or meal prepping for the week, it delivers comfort, flavor, and that little spark of joy that comes from a dish done right.
